knowledge and a deep understanding of 
their local markets, customers and ground 
conditions, our teams are empowered to

of complexity.

Our people and assets are mobile 
which means that we can bring 
together people and equipment 
from all parts of Keller to be a 
single provider of solutions for 
all groundwork	challenges.

Proposal preparation
•  Design engineers and cost 

estimators with local ground 
knowledge and capacity

work is won based on design 
and build tenders.

secures	client	sign-off	 
and payment.

and transferred to the rest 
of the Group.

Chairman’s statement

Keller Group plc  Annual Report and Accounts 2023

The	efforts	of	our	people	
around the world are 
the foundation of our 
success, and for that, we 
are profoundly thankful.

Peter Hill CBE

Chairman

We have recorded 
unprecedented profits,  
marking a significant  
milestone in our journey.”

Contents Generation – Sub PageContents Generation - SectionKeller Group plc  Annual Report and Accounts 2023

Keller has had a truly excellent year, delivering 
a record performance in terms of revenue and 
underlying	profit,	return	on	capital	is	the	highest	
it’s been in 15 years, along with high levels of cash 
generation driving a strong, resilient balance 
sheet, all in a year of continued geopolitical and 
economic uncertainty. 

The	underlying	operating	profit	achieved	
this year surpassed all previous records by a 
substantial margin, and was c. 80% higher than 
the	average	for	the	last	five	years;	underlying	
operating	profit	margin	was	over	6%	for	the	first	
time in eight years, furthermore, our return on 
capital employed reached 23% and stands as the 
highest in our company’s history. These results 
have lifted Keller to a new level and provide a 
new foundation for the Group to progress in 
the future.

The	Group	benefits	from	strong	customer	
demand across a cyclical construction industry. 
Our ability to manage the cycle is enabled by our 
geographic footprint, selective market sectors 
and	the	widest	customer	product	offering	in	the	
industry. These important characteristics mean 
that, as an organisation, we are able to withstand 
challenging conditions in certain markets at any 
given time. The Group’s excellent performance 
overall	in	the	year	is	a	clear	reflection	of	this	and	
was achieved despite challenges in some of 
our businesses.	

Our biggest contributor and main growth driver, 
the North America division, saw underlying 
operating	profit	more	than	double	in	the	
year,	reflecting	a	material	and	sustainable	
improvement in operational performance in the 
core foundations business, as well as better than 
expected resilient pricing in the high-rise sector 
at Suncoast, together with the contribution from 
three large projects in the foundations business. 
Whilst the latter two drivers made a material 
contribution to performance in the year, they 
are not expected to repeat at these levels and 
these	gains	were	partially	offset	by	losses	from	
legacy contracts, legal claims and a reduced 
performance in Canada. 

We saw a disappointing performance in Europe, 
driven by a challenging market backdrop and 
some	difficult	projects	in	the	Nordic	region	
and actions have been taken to improve the 
business’s performance. The performance in 
AMEA (Asia, Middle East and Africa) was mixed, 
with excellent results from Keller Australia 
partially	offset	by	material	losses	in	the	first	half	
at Austral on legacy contracts.

Section 172 statement 
and Code compliance

The Directors have acted to promote the 
success	of	the	company	for	the	benefit	
of shareholders, whilst having regard to 
the matters listed in section 172 of the 
Companies Act	2006	during	2023.

In addition, the Board and the company 
fully applied the principles and complied 
with the provisions of the UK Corporate 
Governance Code.

For more information on how we deliver for our stakeholders see pages 8 and 9.  
Our compliance statements can be found on pages 86 and 94.

Keller continued to make good strategic 
progress during the year in implementing the 
Group’s strategy of more sharply focusing 
Keller’s geographic footprint to drive a more 
profitable,	resilient	and	higher	quality	portfolio	
of	businesses.	The	Group	continues	to	refine	
and restructure as well as withdraw from several 
geographic markets where we are unable to 
provide sustainable returns. 

Our	markets	benefit	from	underlying	demand	
for construction and, notwithstanding some 
specific	short-term	market	conditions,	we	
continue to see good levels of work in our robust 
order	book	and	are	confident	that	the	medium-
term to long-term fundamentals of our business 
remain highly attractive. 

Sustainability and ESG 
(Environmental, Social  
and Governance)
I am the Director responsible for ESG on 
the Board and I believe strongly in Keller’s 
commitment to the best achievable standards 
covering sustainability and ESG and I have a 
strong desire to make a positive change.

Climate	change	is	the	defining	issue	of	our	time	
and against this backdrop both Keller and the 
wider construction industry must make strides 
on the journey to net zero. As the world’s largest 
geotechnical specialist contractor, we have 
the responsibility and opportunity to make a 
difference	to	our	customers	and	society	and	to	
help drive a low carbon future. We are committed 
to reducing the carbon intensity of our work and 
have set out clear targets and action plans for 
our journey to net zero. We have met our short-
term carbon targets and are well on track to 
achieve our longer-term net zero commitments. 
You can learn more about our journey to net zero 
from page 59 onwards. 

Our diversity, equity and inclusion (DEI) 
commitments bring together what we are doing 
across Keller to build a more inclusive workplace. 
While gender equality and empowerment 
remains a priority, we recognise and embrace the 
broadest	definitions	of	diversity.	This	is	important	
because our employees represent the broadest 
range of backgrounds, cultures, experiences 
and insights. We believe this is fundamental to 
the successful delivery of our business strategy 
and to best serve our customers around the 
globe. You can learn more about our Inclusion 
Commitments and the progress we made in 
2023 on page 70. 

Everything we achieve as a business is through 
our people. Their safety, health and wellbeing 
is at the heart of everything we do. At Keller we 
view safety as our bedrock, something on which 
we do not compromise. We have made good 
progress in improving the scores in our leading 
indicators, targeting continuous improvement 
in our Accident Frequency Rate (AFR) and Total 
Recordable Incident Rate (TRIR). In 2023, AFR 
remained	at	0.10,	and	TRIR	improved	to	0.60.	
Despite	achieving	industry-leading	figures	in	
this area, we recognise the need to continually 
improve	and	we	will	not	be	satisfied	until	we	
eradicate harm in the workplace. 

Our business can only be resilient and 
achieve sustainable success if built on strong 
foundations of health and wellbeing. During 2023 
we have continued our focus on all aspects of 
our people’s health and wellbeing. You can learn 
more about Our Foundations of Wellbeing on 
page 75. 

I would like to thank and pay tribute to Keller’s 
people around the globe, often operating under 
difficult	conditions.	Their	commitment	to	safety,	
innovation, quality, sustainability and to the 
protection of the environment was a result of 
their	collective	efforts	and	has	allowed	Keller	to	
uphold the highest standards in the industry. On 
behalf of the Board, I thank them all.

Keller has a notable 30-year history of a maintained 
or growing dividend with a CAGR of just under 
9% since flotation in 1994, and is only one of a few 
FTSE listed companies to have consistently paid 
a dividend over such a period.”

Keller Group plc  Annual Report and Accounts 2023

Chairman’s statement continued

In recognition of the excellent performance in the 
year and Keller’s future prospects, the Board is 
recommending a rebasing of the dividend with an 
increase in the total dividend for 2023 of 20%.”

Board composition and 
development 
The Board welcomed Annette Kelleher as a 
Non-executive Director and Chair Designate 
of the Remuneration Committee, joining on 
1 December 2023. Annette brings a diversity 
of experience and a fresh perspective, and is 
already making a valuable contribution. Annette’s 
biography is set out on page 89 as well as a 
conversation with Annette on page 111. 

Eva Lindqvist has announced her intention to 
retire from the Board and will stand down at the 
end of this year’s Annual General Meeting, having 
served seven years as an independent Non-
executive	Director	and	five	years	as	the	Chair	of	
the Remuneration Committee. Eva leaves the 
Board with our thanks and very best wishes.

We review the Board’s composition regularly and 
are committed to ensuring we have the best 
balance of skills and experience within the Board. 
We have made meaningful progress in achieving 
diversity, with 50% female Board members at 
year end (2022: 50%). We recognise that there is 
more to do in the Executive leadership team and 
below. Further information on the Board and the 
Executive leadership team can be found from 
pages	86 onwards. 

Growing the dividend
Keller has a notable 30-year history of a 
maintained or growing dividend with a CAGR 
of	just	under	9%	since	flotation	in	1994,	and	is	
only one of a few FTSE listed companies to have 
consistently paid a dividend over such a period. 

The Group has a dividend policy to pay a dividend 
that is sustainable and grows over time which 
we have managed to do through both the global 
financial	crisis	and	the	COVID-19	pandemic.	

In recognition of the excellent performance 
in the year and Keller’s future prospects, the 
Board is recommending a rebasing of the 
dividend with an increase in the total dividend 
for 2023 of 20%. This follows the 5% increase 
in the interim dividend and would bring the 
total	amount	of	dividends	for	the	year	to	45.2p	
(2022: 37.7p). If approved, the proposed 2023 
final	dividend	of	31.3p	(2022:	24.5p)	will	be	
paid	on	28	June	2024	to	shareholders	on	the	
register as at the close of business on 31 May 
2024.	Following	this	rebasing,	it	is	expected	that	
there will be a resumption of more typical levels 
of dividend growth thereafter. with the overall 
objective of maintaining a progressive dividend 
over the cycle. 

Outlook 
While the uncertain macroenvironment is 
set	to	continue	in	2024,	the	Board	remains	
confident	that	Keller’s	business	model	and	risk	
management approach will ensure we remain 
highly resilient. Our strategy will support us 
in delivering future underlying growth, as we 
continue to improve on project execution for 
our customers by way of our technical expertise 
and secure new customers through our diverse 
product	offering	across	varied	market	sectors	
and into a focused geographic footprint. 

Peter Hill CBE
Chairman

Approved by the Board of Directors

Electric rigs show glimpse of a greener future

Partnering with leading 
manufacturers
As well as developing our own rigs, we’ve also 
used some of the latest third-party electrical 
equipment available, such as Liebherr’s LB 30 
and LRH 200 ‘unplugged’ deep-foundation 
machines – both of which can be connected to 
a conventional electric supply or powered by 
battery. The LB 30 was successfully used by 
Keller on a secant pile project in Norway in late 
2023, while the LRH 200 was impressive on a 
site in Sweden.

“While the industry moves towards more 
electric vehicles, we believe that a solely 
electric option won’t necessarily be the only 
solution,”	Marcel	adds.	“For	example,	we’re	now	
looking to develop hybrid machines that have 
the	flexibility	to	run	on	battery,	but	which	can	
also run on fuel cell, hydrogen or diesel fuelled 
with	hydro-treated	vegetable	oil	(HVO).	We’re	
exploring all options to reduce our footprint, 
meet our targets and help shape the market.” 

Although the industry 
is still some years 
away from a market 
where electric rigs 
are the norm, Keller is 
committed to steering 
the sector towards 
greener technology.”

Marcel Riedl
Operations	(Equipment)	Director

At Keller, we’re committed to 
reducing our carbon emissions as 
part of our wider efforts to build a  
more sustainable future. 

For decarbonising our equipment, this means 
improving	efficiency,	using	alternative	fuels	
and, when rigs come to the end of their life, 
exploring alternatively powered equipment.

Although the industry is still some years away 
from a market where electric rigs are the norm, 
Keller is committed to steering the sector 
towards greener technology. 

In 2023, KGS – Keller’s in-house equipment 
manufacturer – launched the KB0-E drilling rig 
with an electrical drive. 

“We’ve had electrically driven rigs for the past 
30 years, but these have been smaller drilling 
machines	with	a	niche	market,”	explains	Marcel	
Riedl,	Operations	(Equipment)	Director.	“The	
KB0-E is a new-generation, small-diameter 
rig that’s as powerful as its traditional diesel 
counterpart and can match it for performance.” 

The KB0-E has been trialled on a handful of 
projects in Austria, receiving positive feedback 
from our site teams. Electric rigs not only 
produce zero tailpipe emissions, but they’re 
also quiet, have lower running costs, can 
run in low-emission zones and require less 
maintenance.

Infrastructure renewal
As populations grow and infrastructure ages, 
there’s an imperative to invest in new and greater 
capacity. Geotechnical solutions are often 
complex and sophisticated and large-scale 
and cramped metropolitan environments can 
present additional technical challenges. We have 
the resources and skills to deliver to this scale 
and complexity, a reputation for delivery and the 
proven ability to team up successfully with our 
customers and partners.

Demand for complete solutions
Geotechnical solutions increasingly require 
multiple products. Our broad product portfolio 
ensures	we	can	design	an	effective	and	efficient	
solution while our project management 
capabilities mean we can integrate other 
subcontractors and deliver ‘turnkey’ contracts. 
This reduces the number of interfaces for our 
customers to manage and reduces risk.

Urbanisation
As cities expand they require more sophisticated 
solutions. Larger, taller structures need more 
technically demanding foundations to withstand 
the building loads and provide resilience against 
climate change and acts of nature such as 
rising water levels or earthquakes. We have a 
comprehensive	network	of	regional	offices	
located in major metropolitan areas. This local 
presence keeps us close to our customers and 
the opportunities.

Demand for complete solutions
There	is	a	desire	to	convert	more	brownfield	and	
marginal land. Geotechnical solutions are at the 
fore in releasing the development potential of 
otherwise sterile or derelict areas. Our world-
leading geotechnical engineering team, broad 
portfolio and near shore marine capability, mean 
we can cope with the most complex challenges 
when	working	on	brownfield	or	marginal	sites.

Variety of projects and sectors
Our projects are spread across all construction 
sectors and vary in scale, location, end use and 
geotechnical technique. Project value is typically 
between £25k and £10m, usually short duration 
and with an average value of £500,000.

Niche subsector
Geotechnical specialist contracting is an 
important but niche subsector that commands 
higher margins than general construction. 
Typically geotechnical contracting is around 
0.5% of the construction market.

Projects per year

5,500

Keller’s underlying operating 
margin (2022: 3.7%)

6.1%

Fragmented competition 
We have three types of competitor. Type 
one is the global geotechnical contractor, of 
which there are three, but not all are present 
in all markets. Type two is general contracting-
owned. Type three is local competition with low 
overheads operating in a small region.

Diverse customer base
We have a large client spread which means 
we’re not overly reliant on a few customers. We 
have many repeat customers and our largest 
customer in 2023 represented circa 3% of 
the Group’s revenue. We mostly serve as a 
subcontractor working for a general contractor; 
however, sometimes we also contract directly 
with ultimate client organisations.

Technical complexity
The construction market is becoming 
more digital and sites are increasing in 
sophistication and complexity. We have a 
strong history of innovation.

We leverage our in-house equipment 
manufacturing capacities and develop 
market-leading data acquisition systems to 
control and record our processes, and share 
information with our customers and the 
rest of the supply chain. We can integrate 
instrumentation and monitoring solutions 
and are Building Information Modelling 
(BIM) capable.

Diverse global market
Operating	globally	in	differing	countries	
and across the construction sectors, from 
residential to infrastructure, gives us the 
resilience to trade through national cyclicality. 
The geotechnical market is estimated1 to be 
around £39.5bn worldwide, which includes 
China, Japan, Korea and other regions of 
the world where we are not present. In the 
countries where we choose to operate 
our core markets are around £18.5bn. We 
choose to operate in sustainable markets 
that appreciate the value of the products and 
services Keller provides, have a consistent 
material demand for those services, and 
an acceptable level of risk. With an annual 
turnover	close	to	£3bn,	we	have	a	16%	share	
of those core markets today, and plenty of 
opportunity to secure greater market share.

Keller Group plc  Annual Report and Accounts 2023

17

Overview
Keller has delivered an outstanding performance 
in 2023, with consecutive upgrades to market 
expectations during the year, culminating in 
significant	advancements	in	key	measures	of	
financial	performance.	Revenue	and	underlying	
operating	profit	set	new	records	for	the	Group	
whilst ROCE was the highest in 15 years and all 
evidence our improved project execution.

The management actions taken in the second 
half of 2022, to improve project performance 
in	North	America	generated	a	significant	and	
sustainable improvement in performance in 
2023 and was the main driver of the Group’s very 
strong results. In addition, better than expected 
pricing resilience at Suncoast and a strong 
performance on infrastructure projects at Keller 
Australia	more	than	offset	a	very	disappointing	
project and business performance in Europe, 
particularly in the Nordic region. 

The	increased	profitability,	on	a	consistent	level	
of revenue and working capital, generated a 
strong	cashflow	performance	and	a	continued	
reduction in leverage, which is now at the lower 
end of our target range of 0.5x-1.5x. 

In recognition of the excellent performance 
in the year and the Group’s future growth 
prospects, the Board is recommending a 
rebasing of the dividend with an increase in the 
total dividend for 2023 of 20%, which would 
bring	the	total	dividends	for	the	year	to	45.2p	
(2022: 37.7p).	

Financial performance
Group	revenue	at	£2,966.0m	(2022:	£2,944.6m)	
was similar to the prior year, while underlying 
operating	profit	was	up	67%,	to	£180.9m	(2022:	
£108.6m),	some	80%	higher	than	the	average	
underlying	operating	profit	over	the	last	five	
years. Underlying operating margin increased to 
6.1%	(2022:	3.7%),	the	highest	for	eight	years.	
Cashflow	generation	also	saw	a	significant	
improvement, compared to the prior year, as a 
result of stable working capital performance, 
generating	increased	free	cashflow	of	£103.2m	
and	a	significant	reduction	in	net	debt	(IAS	
17	lender	covenant	basis)	to	£146.2m	(2022:	
£218.8m). This equated to a net debt/EBITDA 
ratio	of	0.6x	(2022:	1.2x),	at	the	lower	end	of	our	
leverage target range of 0.5x–1.5x. 

Operational performance
In	North	America,	revenue	declined	by	6%	(on	
a constant currency basis) largely as a result 
of the completion of the large LNG project at 
RECON at the start of the period, and a slow-
down in residential housing, impacting volume at 
Suncoast	where	revenues	were	down	by	c.14%.	
Our foundations business increased revenues 
by	c.6%,	notwithstanding	an	increase	in	our	
bidding	discipline.	Underlying	operating	profit	in	
North	America	more	than	doubled	to	£169.6m	
driven primarily by a material and sustainable 
improvement in operational performance in the 
foundations business, following the management 
actions taken in the second half of 2022.  
These included the introduction of standard 
operating procedures, an upgraded project 
performance review process, a new variation 
order tracking system and new management 
across some of the business units. The 
foundations business experienced higher than 
normal returns on three large projects, also 
benefitted	profitability.	These	one-off	gains	were	
partially	offset	by	losses	from	legacy	contracts,	
legal claims and a reduced performance in 
Canada.	The	division	also	benefited	from	better	
than expected resilient pricing at Suncoast, 
which is now unwinding as expected. The 
increase	in	profitability	saw	underlying	operating	
margin	increase	to	9.6%	(2022:	4.3%).	

In Europe, although revenue increased modestly 
by	4.2%	on	a	constant	currency	basis,	this	
reflected	a	very	mixed	backdrop	with	widespread	
weak demand in the residential and commercial 
sectors	offset	by	revenue	from	larger	projects	in	
the infrastructure sector. Underlying operating 
profit	reduced	significantly,	down	94.0%	
on a constant currency basis, primarily as a 
result of poor project performance and cost 
management in the Nordic region and also an 
increasingly competitive environment across 
Europe in a declining market. The adverse mix 
of contracts in the UK and the increasingly 
competitive market conditions, particularly 
in North East Europe, also contributed to the 
underlying operating margin reducing to 0.3% 
(2022:	4.5%).	The	adverse	project	performance	
in the Nordics is not expected to continue into 
2024	and	management	actions	have	been	
taken to drive improvement there and the region 
more generally.

In	AMEA,	revenues	increased	by	34.1%	on	
a constant currency basis, driven by record 
volumes in Keller Australia as a result of a strong 
infrastructure	market,	delivery	of	the	first	works	
order at the NEOM project in Saudi Arabia and 
robust trading in India. Underlying operating 
profit	increased	significantly	to	£22.6m	driven	
primarily by the increased volume and much 
improved	operational	execution	and	profitability	
in Keller Australia. The Middle East, including 
NEOM, showed a modest uplift compared with 
prior year. While Austral returned to a sustainable 
profit	in	the	second	half	of	the	year,	this	was	
insufficient	to	offset	the	significant	loss	on	
legacy	contracts	experienced	in	the	first	half	of	
the year. The overall operating margin for the 
division	increased	to	4.4%	(2022:1.7%).

Strategy
In	2023,	we	were	effective	in	executing	our	
strategy to be the preferred international 
geotechnical specialist contractor focused on 
sustainable markets and attractive projects, 
generating long-term value for our stakeholders. 
Our local businesses leverage the Group’s scale 
and expertise to deliver engineered solutions 
and operational excellence, driving market share 
leadership in our selected segments.

The	benefit	of	our	strategy	has	been	evidenced	
by our improved performance compared 
with recent years, with the Group delivering a 
significant	increase	in	both	its	operational	and	
financial	performance.	

Progress on strategic priorities 
in 2023
We have made considerable progress in recent 
years,	rationalising,	restructuring	and	refining	
the	Group’s	geographic	and	service	offering	
to create a more focused and higher quality 
portfolio of businesses. During 2023 we made 
the strategic decision to exit Cyntech Tanks, 
Egypt, South Africa and Kazakhstan, all small 
non-core, economically uncertain markets 
which do not align with our strategy. We continue 
to evaluate our portfolio and potential further 
incremental rationalisation. In Saudi Arabia 
we obtained full control over our joint-venture 
business in the country to enable us to take 
advantage of future opportunities in the region.

Chief Executive’s statement continued

In North America, we restructured three related 
business units into one; the Central, Southeast 
and Florida business units were combined to 
become South Central. This consolidation 
provided the opportunity to increase both the 
effectiveness	and	efficiency	of	expertise	and	
key	resources,	and	exemplifies	the	pursuit	of	
operational leverage and economies of scale 
which is a key aspect of our strategy. 

We	continued	to	focus	our	efforts	on	our	
operational execution across all our businesses, 
as evidenced by recent results, and we made 
further progress implementing the enterprise 
resource planning (ERP) system, Project 
Performance Management (PPM) and several 
other initiatives that will incrementally improve 
operational execution in the medium term. 

Strategic priorities for 2024
Having established a refreshed and more 
resilient base for our business, we are looking to 
grow market share within our existing geographic 
footprint, through both organic investment and 
targeted bolt-on M&A. We will be customer 
focused locally through our branch structure 
and	obtain	the	benefit	of	operational	leverage	by	
gaining high quality, leading market share in our 
chosen markets. Organic investment will include 
initiatives to increase the cross selling of existing 
services into established branches that don’t 
currently provide those services, and investing 
in our people to build on our technical expertise 
and	influence.	The	Group’s	disciplined	approach	
to M&A activity will be focused on expanding the 
service	offering	and	building	critical	mass	in	key	
markets, and will be biased towards markets with 
higher rates of growth. 

We	will	offer	our	customers	alternative	designs	
and engineered solutions that meet their 
specifications	whilst	reducing	the	total	cost	to	
the client and, wherever possible, also reducing 
the environmental impact of project. 

We will continue evaluating our portfolio of 
assets to identify opportunities for divestment 
or consolidation.

We remain committed to investing in key growth 
areas that align with our long-term strategic 
objectives to focus on sustainable markets and 
attractive projects, generating long-term value 
for our stakeholders. 

Sustainability and Environmental, 
Social and Governance (ESG)
We base our ESG and sustainability approach on 
the UN Sustainable Development Goals (SDGs). 
We particularly focus on those SDGs that are 
most closely aligned to Keller’s core business 
and where we can have the greatest impact. We 
divide these SDGs into global initiatives, which 
we target across the Group, and local initiatives 
that are more relevant to our local business units 
and markets. 

We are progressing well against the carbon 
reduction targets we set out two years ago to 
achieve net zero by 2050. We will be net zero 
across all three emission scopes by 2050; net 
zero on Scope 2 by 2030, net zero on Scope 1 by 
2040	and	net	zero	by	2050	on	Operational	Scope	
3 (covering business travel, material transport and 
waste disposal). The short, medium and long-
term actions required to achieve these goals are 
in progress and in some instances we are ahead 
of target, particularly around our Scope 2 carbon 
reduction.	The	Group	reduced	emissions	by	48%	
from	our	2019	baseline,	significantly	ahead	of	our	
target of 38%. 

Scope 1 emissions covers our direct emissions 
from fuel use. We successfully deployed our new 
KB0-E electric rig, which together with a number 
of hired electric third party rigs have enabled 
us to begin to reduce life cycle emissions in 
areas where decarbonised electricity grids 
are available.

We remain committed to investing in key 
growth areas that align with our long-term 
strategic objectives to focus on sustainable 
markets and attractive projects, generating 
long-term value for our stakeholders.”

Scope 3 emissions, covering all other indirect 
emissions, mostly arise from our supply chain. 
In 2023, we trained our engineers to calculate 
and reduce the emissions from our use of 
cement and steel and we have started to develop 
an action plan to decarbonise our cement 
design mixes.	

On climate risks and opportunities, we continue 
to model and mitigate both our transition 
and physical risks. In terms of more local 
environmental initiatives, we led a project to 
highlight how the geotechnical sector can help 
contribute to the circular economy and on water 
reduction at site in our MEA business.

The Group’s safety focus remains relentless, 
and our key safety metric, the accident 
frequency	rate	(AFR),	was	flat	year	on	year,	with	
a	small	increase	in	injuries	in	AMEA	offset	by	
an improvement in Europe. There have been 
a number of important initiatives in the year 
including a Group-wide assurance programme 
to ensure safety policies, procedures and 
culture are truly embedded in operations. The 
second Global Safety Week was successful and 
a recently refreshed management safety visit 
process has been launched with encouraging 
results. The employee traction and general 
progress on almost all the safety programmes in 
the year have been encouraging.

Our Inclusion Commitments serve as the 
blueprint for setting priorities and fostering 
alignment and progress across the entire 
Group. In 2023, these commitments became 
more deeply ingrained within the fabric of our 
company. This is crucial as we endeavour to 
cultivate a workplace that is increasingly diverse, 
equitable, and inclusive.

Regarding partnerships, we remain committed 
to collaborating with organisations dedicated 
to driving positive change and those that align 
with our focus on the UN SDGs. In pursuit of this 
objective, we have a three-year partnership with 
UNICEF UK, providing a funding contribution of 
£250,000 in 2023 towards its Core Resources 
for Children initiative. Keller’s unrestricted 
funding enables UNICEF to swiftly respond to 
emergencies worldwide. Additionally, throughout 
Europe and across the Group, our employees 
continue to show support for ‘Fundacja KELLER’, 
a charitable foundation established by Keller. 
This	foundation	specifically	aids	our	Ukrainian	
employees and their families who have been 
impacted	by	the	ongoing	conflict.

Keller Group plc  Annual Report and Accounts 2023

People
Paul Leonard has been appointed President 
North America, and will join the Group shortly. 
Paul, a highly experienced industry professional 
with a long tenure at Exxon, was most recently 
at Wood Group PLC in the role of President 
of Transformation for the Global Consulting 
business. He is a seasoned expert in energy 
and construction, with a proven track record 
in project delivery, and will build on the recent 
improved performance in the division.

Outlook
In 2023 the Group delivered a record set of 
financial	results,	establishing	a	new	foundation	
for future long-term growth and supporting a 
material rebasing of the dividend with a full-year 
increase of 20%. Whilst political and macro-
economic uncertainties will undoubtedly remain 
and impact our markets in the short term, our 
current level of trading together with our robust 
order book mean that we enter the new year 
with	confidence.	

The strong momentum of the business is 
encouraging and whilst inevitably there will 
be	fluctuations	across	the	Group,	our	diverse	
revenues and improved operational delivery 
underpin	our	expectation	that	2024	will	be	
another year of underlying progress. 

The	significant	improvement	in	business	
performance and continued disciplined 
execution of our strategy will provide both 
resilience in the short term and drive growth 
in the long term, through both organic and 
targeted M&A opportunities. Accordingly, 
we view the Group’s prospects with 
increased confidence.

Michael Speakman
Chief	Executive	Officer

Approved by the Board of Directors and 
authorised	for	issue	on	4	March	2024.

We constantly review the way in which we 
manage and structure the Group in order 
to	respond	most	effectively	to	our	evolving	
markets,	and	maximise	the	potential	benefits	
of our strategy. Recently we have made the 
decision to restructure two of our divisions, 
Europe	and	AMEA	(Asia-Pacific,	Middle	East	
and Africa). The responsibility of the Middle East 
Business Unit (including NEOM) will transfer to 
Europe to create the Europe and Middle East 
Division (EME). Peter Wyton, who has 33 years of 
industry experience and has most recently and 
successfully led the AMEA Division, will become 
the President of EME. The balance of the former 
AMEA Division will form a newly created Asia-
Pacific	(APAC)	Division	and	will	be	led	by	Deepak	
Raj. Deepak has been with Keller for 20 years and 
most recently led the turnaround of the Austral 
business in Australia. There is no impact of this 
restructuring on our North America Division.

In our ongoing commitment to excellence and 
growth, we remain steadfast in developing 
our most valuable asset, our people. Through 
structured programmes like the Project 
Manager Academy, Field Leadership Academy, 
and several other leadership initiatives, we are 
dedicated to nurturing and advancing the skills 
of our people, and have made several internal 
promotions to important roles within the Group. 
This focus on in-role development, coupled with 
the right opportunities for exposure within the 
organisation, has created many opportunities for 
internal advancement. 

At the core of our operations and achievements 
lies our diverse and talented team; our people 
are at the heart of everything we do. This 
past year, which was both challenging and 
successful, showcased the tremendous 
dedication, hard work and expertise of our 
teams.	As	we	reflect	on	the	year’s	journey,	we	
extend our gratitude to all our people around 
the world for their unwavering commitment 
and exceptional performance.

In	North	America,	revenue	was	down	by	6.4%	
(on a constant currency basis) largely driven 
by the completion of the large LNG project at 
RECON at the start of the period, and a slow-
down	in	residential	housing	affecting	Suncoast,	
where	revenues	were	down	by	c.14%.	Our	
foundations business increased revenues 
by	c.	6%,	with	an	increase	in	our	bidding	
discipline.	Underlying	operating	profit	more	
than	doubled	to	£169.6m,	driven	by	a	material	
and sustainable improvement in operational 
performance in the foundations business, 
better than expected pricing resilience at 
Suncoast and the strong contribution from 
three large projects in the foundations 
business.	However,	these	one-off	gains	were	
partially	offset	by	losses	from	legacy	contracts,	
legal claims and a reduced performance in 
Canada. This resulted in underlying operating 
margin	increasing	to	9.6%.	The	accident	
frequency rate, our key safety metric, remained 
flat	versus	the	prior	period	at 0.09.

The foundations business had an outstanding 
year. Management actions taken in the second 
half of 2022 have resulted in a sustainable 
improvement in operational performance. These 
include the introduction of standard operating 
procedures, an upgraded project performance 
review process, a new variation order tracking 
system and new management across some of 
the business units. The supply chain disruption 
that had previously impacted productivity across 
the market in the prior period abated, also 
bolstering performance in the year. In addition, 
the	business	benefitted	from	the	contribution	
from three large projects that were particularly 
well executed, and delivered materially higher 
than	normal	levels	of	contract	profitability	
which	are	considered	one-off	in	nature	and	
not	expected	to	repeat	at	these	levels	in	2024.	
Overall the foundations business is expected 
to sustain its improved underlying operational 
performance	in	2024.

Suncoast had a very strong year, despite the 
macro headwinds contributing to lower volumes 
in the residential sector. Whilst revenue was 
down	versus	the	prior	year,	profitability	increased	
due to resilient pricing in the high rise sector. This 
large,	non-recurring	benefit	is	unwinding	in	2024	
as expected. 

Moretrench Industrial, our business which 
operates in the highly regulated industrial, 
environmental and power segments, delivered 
revenue	and	profit	in	line	with	expectations	and	
the prior year. At RECON, the geoenvironmental 
and industrial services company, revenue

completion of the large LNG contract in the

Helping Hyundai  
accelerate to the future

The continued rise in demand for 
electric vehicles has led to car 
manufacturers in the US racing to 
build new production facilities.

In recent months, Keller has been a 
trusted partner on several of these critical 
construction projects, for brands including 
Ford in Tennessee, Volkswagen in South 
Carolina and, as Keller Project Executive Ryan 
Smith explains, Hyundai in Georgia. 

Hyundai is looking to get its $7.6 billion, 
3,000-acre ‘metaplant’ built and producing 
cars in just two years. It’s an ambitious target 
– a project of this size would normally take 
twice as long to construct. 

“We	first	met	with	Hyundai	in	August	2022	
when the project was an idea and the site  
was forest,” says Ryan Smith. “By January  
we were on site and hard at work.”

Fast forward a year and Keller has installed over 
15,000 rigid inclusions and approximately 8,000 
augercast piles (over 1.5 million linear feet of 
piles)	to	support	eight	key	buildings,	including	
the site’s main plant.

The highest levels of quality
Installing such a large amount of piles in such a 
short space of time hasn’t been easy, but Keller 
has maintained a relentless production pace 
while ensuring the highest quality.

“Because of the incredibly fast pace, plans 
were sometimes changing on an almost daily 
basis, so our brilliant team has had to be very 
flexible,	reactive	and	proactive	to	ensure	we	
can deliver what the client needs within a 
demanding timeframe.” he adds. “And when 
things do change, you have to make sure that 
the quality doesn’t slip – otherwise problems 
creep in and it can snowball quickly.”

This has been a hugely successful 
project and we’re proud to be 
involved in a booming sector that 
will have a positive impact on 
the economy.”

In	Europe,	revenue	increased	modestly	by	4.2%	
on a constant currency basis, while underlying 
operating	profit	reduced	significantly,	down	94%	
on	a	constant	currency	basis,	reflecting	tough	
markets and some challenging projects. 

In general, across the division, operations 
continued	to	be	affected	by	ongoing	weak	
demand in the residential and commercial 
sectors which has resulted in lower volumes in 
these sectors. However, revenue from larger 
projects in the infrastructure sector has more 
than	offset	these	shortfalls.	Underlying	operating	
margin	reduced	to	0.3%	(2022:	4.5%)	as	a	result	
of the ongoing competitive market environment 
and reduced margin performance on some 
particularly challenging contracts. The accident 
frequency	rate	reduced	from	0.26	to	0.20.	

Our North-East Europe business, which 
comprises Poland and the Baltic countries, 
was	affected	by	both	economic	and	political	
uncertainty	impacting	investor	confidence	and

As	a	consequence	revenue	was	significantly	
behind	a	strong	prior	year	comparable.	Profit	
was down on the prior year on the lower volume 
and the tightening of margins in the challenging 
market. Towards the end of the year volumes 
increased, in part driven by work relating to CPK in 
Poland, a large government funded project that 
will include the construction of a new highspeed 
rail and road network across Poland, and may also 
include a new airport. 

South-East Europe and Nordics delivered further 
revenue growth in 2023. The largest gains were 
reported in Norway, Sweden and Switzerland 
largely from rail and road infrastructure projects, 
and in Hungary, where a number of industrial 
sector projects were successfully completed. 
In the Nordic countries, work has progressed 
on the two substantial multi-year infrastructure 
contracts, though both projects encountered 
challenges which created a drag on margins. 
Performance in the Nordics region generally was 
significantly	below	expectations,	impacted	by	
contract performance and cost management 
issues, and as a result we have made changes 
to the management team and restructured the 
cost base.

The continuing focus on the infrastructure sector 
provides ongoing project opportunities until we 
see a recovery in the residential and commercial 
sectors.	In	2024	we	expect	market	conditions	
to remain challenging, however we anticipate an 
improvement in operating margin.

The Europe order book at the end of the period 
was	£317.6m,	-7.3%	lower	than	the	prior	year	
on a constant currency basis, as a result of the 
completion of work on some large multi-year 
infrastructure projects. 

Our UK business continued to make good 
progress in the year on the High Speed 2 rail 
contract with lower levels of project revenue 
against	the	prior	period	reflecting	the	phasing	of	
work. Increased volumes were achieved in the 
core	UK	foundations	business,	which	benefitted	
from the completion of a large industrial project 
in the North East of England, albeit business 
unit	margins	were	affected	by	the	mix	of	
work performed.

In Central Europe, revenue increased in the 
period, helped by work delivered on a large 
rail project in Germany that commenced in 
the fourth quarter. Margins were adversely 
affected	by	market	pressure	in	the	residential	
and commercial sector and the associated 
weighting towards infrastructure work. 

South West Europe delivered growth in both 
revenue	and	operating	profit.	The	Iberian	markets	
were	affected	by	lower	levels	of	revenue,	with	
the uncertainty of Spanish elections in the 
year	affecting	local	decision	making	on	project	
investments. France performed well and the 
strategic cross selling of products across the 
South Western Europe markets continues to be 
a key	driver	of	growth.	

As part of our continuing strategic review of our 
asset portfolio, we took the decision to exit the 
Kazakhstan market. 

Despite various actions taken in response to 
the prevailing macro-economic conditions, 
financial	performance	for	the	division,	as	a	whole,	
during	2023	was	disappointing.	Specifically,	we	
have taken action in the Nordics businesses to 
address contract performance and cost issues. 

Expanding Poland’s  
largest port

This year saw Keller successfully 
complete complex works on a 
new terminal at Poland’s largest, 
fastest-growing shipping 
container facility. 

Baltic Hub in Gdansk is the only deep-water 
port in the Baltic Sea capable of welcoming 
ocean vessels from the Far East. Once it 
becomes operational, the new terminal will 
expand the Hub’s handling capacity by 1.5m 
containers to 4.5m a year. 

Having earned a strong reputation working 
on	the	Hub’s	first	two	terminals,	Keller	
was	selected	by	the	Budimex	and	DEME	
Group consortium to design and build a new 
18m-deep, 720m-long main terminal quay wall, 
as well as a 550m-long northern wall, including 
all steel anchoring elements. 

The scope also included compacting part of 36 
hectares	of	reclaimed	land	using	vibroflotation,	
alongside jet grouting and reinforced CFA piles 
to support the huge ship-to-shore cranes. 

Challenging conditions
“This was an extremely challenging project 
that involved	our	teams	working	night	and	
day for well over a year, often in challenging 
weather conditions,” says Leszek Adamczyk, 
Project Director.  

“Although we’d worked on the other terminals, 
this	was	the	first	time	we’d	designed	and	
executed the steel structures for the quay, so 
all the responsibility was on us to deliver a high-
quality, sustainable solution.”

Much	of	the	work	had	to	be	carried	out	from	
barge-mounted cranes on the sea, and our 
team placed great emphasis on safety, quality 
and the environment – making sure no spoils 
entered the ocean and that marine life was  
well protected. 

With the work successfully completed on 
this third terminal, Keller is now hoping to be 
involved	in	the	forthcoming	fourth	and	fifth	
terminal projects.

Near-shore marine work is a 
growing market here in Poland  
and with this latest project Keller 
has shown we’re the trusted 
strategic partner of choice.”

In	AMEA	(Asia-Pacific,	Middle	East	and	Africa),	
revenues	increased	by	34.1%	on	a	constant	
currency basis, driven by record volumes in 
Keller	Australia,	delivery	of	the	first	works	order	
at NEOM and robust trading in India. Underlying 
operating	profit	increased	significantly	to	
£22.6m	driven	by	higher	volumes	as	well	as	
improved operational execution in Keller 
Australia, the NEOM project and the return to 
profit	in	the	second	half	at	Austral.	The	accident	
frequency	rate	increased	slightly	to	0.04.	

Keller Australia delivered a record performance 
with high levels of volume driven by federal and 
state government spending, particularly in the 
infrastructure sector, combined with improved 
operational execution. It is expected the federal 
and state government spending will begin to 
ease	through	2024.	

Austral, as anticipated, returned to a sustainable 
profit	in	the	second	half,	this	was	insufficient	to	
offset	the	significant	loss	on	legacy	contracts	
experienced	in	the	first	half	of	the	year.	The	new	
management team has done an excellent job  
in turning the business around and resetting  
the business for future growth.  

The leadership team has been restructured and 
strengthened. New processes were introduced, 
increasing the level of scrutiny of project reviews, 
improving the reliability of forecasts and driving 
improved	profitability.	In	2024,	a	full	year	profit	
is expected.

In ASEAN, the market recovery has been slower 
than expected, with continued market softness 
and low levels of activity, particularly in Malaysia 
and	Indonesia.	Volumes	were	broadly	in	line	with	
prior	year	with	lower	levels	of	profitability	due	
to high levels of competition and project mix. It 
is	expected	that	trading	will	improve	in	2024	as	
previously delayed projects come on stream. 

Keller India performed well, delivering 
revenue	and	profit	growth	in	the	period.	New	
contract wins in the industrial, manufacturing 
and commercial sectors supported the 
business’s continued leading position in the 
petrochemical sector.

We continually review our portfolio and have 
taken the strategic decision to exit Egypt and 
our remaining	businesses	in	Sub-Sahara	Africa.	

The AMEA order book at the end of the period 
was	at	£266.9m,	down	5.1%	(on	a	constant	
currency basis) on the prior year. The decrease 
is predominantly driven by the depletion in 
the order book at Keller Australia as major 
projects progressed.	

After	a	soft	first	half,	our	MEA	business	
performed ahead of expectations with a strong 
end to the period particularly in UAE and Saudi 
Arabia. At NEOM, following the signing of the 
overall Framework Agreement in 2022, we 
completed	the	first	Works	Order	in	relation	to	
The	Line,	in	the	first	quarter	of	2023,	worth	
c.£40m.	While	we	await	further	work	orders	
in relation to The Line we have redeployed 
resources elsewhere. At Trojena, the winter 
resort development at NEOM, we have recently 
been awarded a work package worth c.US$80m 
and we have mobilised to site with work 
expected	to	be	completed	by	the	end	of	2024.	
We continue to take a measured and disciplined 
approach to the opportunities provided by 
the project.

Breathing new life into a Sydney landmark

Detailed planning beforehand and 
constant communication on site 
showed how Keller can add value 
to even the biggest most complex 
projects.”

Gabriel Miler
Project	Manager

Performing to the highest standard
Constructing the wall wasn’t just a challenge 
because of what was in the ground; the site 
itself is just a small strip of reclaimed land with 
Blackwattle Bay on one side and a main road 
on the other. The wall also needed to perform 
to	the	highest	standard,	with	a	deflection	
tolerance of less than 30mm and a water 
ingress of less than 10 litres a second.

Once the preliminary works were completed, 
the	team	was	able	to	finish	the	main	task	of	
constructing the retaining wall, installing CFA 
piles, jet grout columns and ground anchors.

“We had a lot of constraints on this project,” 
adds Gabriel, “but the detailed planning 
beforehand and constant communication on 
site showed how Keller can add value to even 
the biggest, most complex projects.” 

Sydney Fish Market is one of 
the city’s most popular tourist 
destinations and the lifeblood of 
Australia’s seafood industry.

The landmark is undergoing a massive 
transformation that will see operations move 
to a sleek new 35,000m2 complex, creating 
a world-class waterfront destination with 
restaurants, promenade and public spaces.

Keller	was	chosen	by	long-time	client	Multiplex	
to design and construct the land-side shoring 
wall that will support the site’s basement car 
park	–	a	project	made	more	difficult	due	to	a	
spatially and environmentally challenging site.

While the original proposal called for the wall 
to be built using cased bored piles, Keller 
recommended a combination of continuous 
flight	auger	(CFA)	piles	and	jet	grouting.	

“The reason for this was multiple obstructions 
in the ground, including old concrete structures 
and	steel	beams,”	says	Gabriel	Miler,	Project	
Manager.	“CFA	and	jet	grouting	allowed	us	to	
work around them rather than spend valuable 
time trying to dig them out.”

 Details of non-underlying items are set out in note 9	to	the	consolidated	financial	statements.	Reconciliations	to	statutory	numbers	are	set	out	in	the	adjusted	performance	measures	
section on page 215. 

Underlying operating profit
The	underlying	operating	profit	of	£180.9m	
was	67%	up	on	prior	year	(2022:	£108.6m)	on	
an actual and constant currency basis. In North 
America,	underlying	operating	profit	more	than	
doubled	to	£169.6m	(2022:	£82.0m),	due	to	
a sustainable improvement in the operational 
performance in the foundations business, 
better than expected pricing resilience at 
Suncoast and the contribution from three large 
projects in the foundations business. In Europe, 
underlying	operating	profit	reduced	significantly	
to £1.8m (2022: £29.1m) as a result of reduced 
margin performance on some particularly 
challenging contracts in the Nordics region 
and the increasingly competitive environment 
across Europe in a declining market. In 
AMEA,	underlying	operating	profit	increased	
significantly	to	£22.6m	(2022:	£6.6m),	driven	by	
higher volumes as well as improved operational 
execution	and	profitability	in	Keller	Australia,	
uplift in the Middle East (including NEOM) and the 
return	to	profit	in	the	second	half	at	Austral.	

Share of post-tax results from joint 
ventures
The Group recognised an underlying post-tax 
profit	of	£0.8m	in	the	year	(2022:	£1.5m)	from	
its share of the post-tax results from joint 
ventures. The share of the post-tax amortisation 
charge	of	£0.6m	(2022:	£1.2m)	arising	from	the	
acquisition of NordPile by our joint venture KFS 
Oy in 2021 is included as a non-underlying item. 
No dividends (2022: nil) were received from joint 
ventures in the year.

Statutory operating profit
Statutory	operating	profit	comprising	underlying	
operating	profit	of	£180.9m	(2022:	£108.6m)	
and non-underlying items comprising net costs 
of	£27.8m	(2022:	£40.8m),	increased	by	126%	
to	£153.1m	(2022:	£67.8m).	The	increase	in	
statutory	operating	profit	is	a	reflection	of	the	
increase	in	underlying	operating	profit	in	2023,	
combined with a decrease in non-underlying 
operating costs. The non-underlying costs are 
set out in further detail overleaf. 

Revenue
Revenue	of	£2,966.0m	(2022:	£2,944.6m)	was	
up 1% at actual foreign exchange rates and at 
constant currency, driven by increased trading 
volumes in AMEA and to a lesser extent Europe, 
offset	by	a	reduction	in	North	America.	In	North	
America,	revenue	reduced	by	6.4%	on	a	constant	
currency basis driven by the completion of the 
large LNG project at RECON at the start of the 
period.	In	AMEA,	revenues	increased	by	34.1%	
on a constant currency basis, driven by record 
volumes	in	Keller	Australia,	delivery	of	the	first	
works order at NEOM and robust trading in Keller 
India. In Europe, revenue increased modestly by 
4.2%,	on	a	constant	currency	basis,	reflecting	
widespread weak demand in the residential and 
commercial	sectors	offset	by	revenue	from	
larger projects in the infrastructure sector. 

We	have	a	diversified	spread	of	revenues	across	
geographies, product lines, market segments 
and end customers. Customers are generally 
market	specific	and,	consistent	with	the	prior	
year, the largest customer represented less 
than	4%	of	the	Group’s	revenue.	The	top	10	
customers represent 15% of the Group’s 
revenue (2022: 17%). The Group worked on 
c.5,500 projects in the year with 51% (2022: 
54%)	of	contracts	having	a	value	between	
£25,000 and £250,000, demonstrating a 
low customer concentration and a wide 
project portfolio.

Keller Group plc  Annual Report and Accounts 2023

Chief Financial Officer’s review continued

Net finance costs
Net	underlying	finance	costs	increased	by	
82% to £27.5m (2022: £15.1m). The increase 
was driven predominantly by the increase in 
underlying interest rates, despite a decrease in 
the average net debt levels through the year. In 
August, the Group received the proceeds from 
a new $300m private placement of loan notes, 
which were used to repay existing borrowings. 
The	Group’s	borrowings	are	now	largely	at	fixed	
interest rates. The average net borrowings, 
excluding	IFRS	16	lease	liabilities,	during	the	
year were	£224.8m	(2022:	£252.1m).	

Taxation
The	Group’s	underlying	effective	tax	rate	
increased to 25% (2022: 22%), largely due 
to	the	change	in	the	profit	mix	of	where	the	
Group is subject to tax. Cash tax paid in the year 
increased	from	£5.9m	to	£72.7m.	The	significant	
increase in tax paid is driven by the increased 
profitability	in	the	US,	resulting	in	tax	paid	of	
c£46m	(2002:	£1m).	In	addition,	Keller	delayed	
the	payment	of	its	FY22	tax	bill	(c£24m)	to	2023	
as it was expecting a law change to materialise 
before the payment became due. As the law did 
not change, the tax payable for FY22 was settled 
in 2023. Further details on tax are set out in note 
12	of	the	consolidated	financial	statements.	

Non-underlying items
The items below have been excluded from the 
underlying results and further details of non-
underlying items are included in note 9 to the 
financial	statements.	The	total	non-underlying	
items	in	operating	profit	in	the	year	decreased	
to	£27.8m	(2022:	£40.8m),	due	to	the	reduction	
in amortisation of acquired intangible assets 
and the non-repeat of historic contract costs 
in the year.

Non-underlying items in operating profit
The Group is continuing the strategic project to 
implement a new cloud computing enterprise 
resource planning (ERP) system across the 
Group. As this is a complex implementation, 
project costs are expected to be incurred over 
a	total	period	of	five	years.	Non-underlying	ERP	
costs	of	£7.5m	(2022:	£6.3m)	include	only	costs	
relating directly to the implementation, including 
external consultancy costs and the cost of 
the dedicated implementation team. Non-
underlying costs does not include operational 
post-deployment costs such as licence costs for 
businesses that have transitioned. 

The goodwill impairment of £12.1m (2022: 
£12.5m) relates to the UK business where a 
downward revision to the medium-term forecast 
has resulted in the full impairment of the goodwill 
as the forward projections did not fully support 
the carrying value of the goodwill. Goodwill 
impairment in the prior year of £12.5m related to 
Austral and the Swedish business.

Exceptional restructuring costs of £2.8m (2022: 
£5.3m) in the year comprises £0.5m (2022: 
£1.9m) in the Europe Division and £2.3m (2022: 
credit	of	£0.6m)	in	AMEA.	In	Europe,	the	costs	
related to the scheduled exit of the Kazakhstan 
business and in AMEA, costs arose from the 
mothballing of the Egypt business. In 2022, 
we also incurred restructuring costs in North 
America	(£3.4m)	and	in	the	centre	(£0.6m).	In	
addition, the exit from Kazakhstan resulted in a 
£0.4m	impairment	of	trade	receivables,	in	2022	
we incurred a £0.3m impairment in respect of 
trade receivables in Ukraine.

A loss on disposal of £0.1m was realised on 
the disposal of the Cyntech Tanks business in 
Canada in October 2023. 

The £0.8m gain on disposal of assets held 
for sale relates primarily to the sale of assets 
owned by the now closed Waterway business in 
Australia. Impairment charges for these assets 
had previously been charged to non-underlying 
items in prior periods and therefore the 
corresponding	profit	on	disposal	of	the	assets	is	
also recognised as a non-underlying item.

The	classification	of	costs	as	non-underlying	is	
a management judgement and is reviewed on a 
regular basis.

Amortisation of acquired intangibles
The £5.1m (2022: £10.3m) charge for 
amortisation of acquired intangible 
assets relates to the RECON, Nordwest 
Fundamentering, GKM Consultants and 
Moretrench acquisitions. In addition, we have 
incurred	£0.6m	(2022:	£1.2m)	of	amortisation	
of joint venture intangibles which relates to 
NordPile, an acquisition by the Group’s joint 
venture interest KFS Finland Oy.

Non-underlying taxation
A non-underlying tax credit of £3.0m (2022: 
£9.0m) relates entirely to the tax impact of the 
non-underlying	loss	for	the	year.	In	2022,	£4.7m	
of the credit related to the tax impact of the non-
underlying	loss	and	the	£4.3m	remainder	arose	
from the reversal of the valuation allowance 
against deferred tax assets in Canada that was 
recognised through the non-underlying tax 
charge in prior years. 

Earnings per share
Underlying diluted earnings per share increased 
by 53% to 153.9p (2022: 100.7p) driven by higher 
operating	profit	partially	offset	by	the	increase	
in	finance	costs	and	a	higher	effective	tax	rate	in	
the year. Statutory diluted earnings per share was 
120.5p	(2022:	62.4p)	which	includes	the	impact	
of the non-underlying items.

Dividend
The	Board	has	recommended	a	final	dividend	of	
31.3p	per	share	(2022:	24.5p	per	share)	which,	
following the interim dividend for 2023 of 13.9p 
(2022: 13.2p), brings the total dividend for the 
year	to	45.2p	(2022:	37.7p),	an	increase	of	
20%. The 2023 dividend earnings cover, before 
non-underlying	items,	was	3.4x	(2022:	2.7x).	If	
approved,	the	proposed	final	dividend	of	31.3p	
(2022:	24.5p)	will	be	paid	on	28	June	2024	to	
shareholders on the register as at the close of 
business	on	31	May	2024.	

Keller Group plc has distributable reserves of 
£190.8m at 31 December 2023 (2022: £122.1m) 
that are available to support the dividend policy, 
which	comfortably	covers	the	proposed	final	
dividend for 2023 of £22.7m. Keller Group plc is 
a non-trading investment company that derives 
its	profits	from	dividends	paid	by	subsidiary	
companies. The dividend policy is therefore 
impacted by the performance of the Group, 
which is subject to the Group’s principal risks and 
uncertainties as well as the level of headroom on 
the Group’s borrowing facilities and future cash 
commitments and investment plans.

Free cash flow
The	Group’s	free	cash	flow	was	an	inflow	of	
£103.2m	(2022:	outflow	of	£33.8m)	and	the	
improvement was driven by the reversal of the 
increased working capital demands in the prior 
year.	Free	cash	flow	has	also	been	impacted	
by the timing of US tax payments. The basis of 
deriving	free	cash	flow	is	set	out	overleaf.

Working capital
Net working capital decreased by £2.7m (2022: 
increase	of	£110.5m)	reflecting	a	significant	
reduction in inventory levels at Suncoast, partially 
offset	by	a	decrease	in	trade	and	other	payables.	
The	net	movement	comprises	a	£26.8m	
decrease in inventories and a £1.5m decrease in 
trade	and	other	receivables,	offset	by	a	decrease	
in	trade	and	other	payables	of	£25.6m.	

An	increase	in	provisions	and	retirement	benefit	
liabilities improved the working capital by £12.1m 
(2022:	decrease	of	£13.4m).	This	reflects	an	
increase in provisions, as the amounts provided 
for contract and legal disputes exceeded 
the amounts settled, with fewer large legal 
or contract disputes settled in the year. This 
excludes	the	cash	outflow	on	restructuring	
provisions and other items included in non-
underlying costs which are presented within non-
underlying	items	in	the	free	cash	flow calculation.

Capital expenditure
The Group manages capital expenditure tightly 
whilst investing in the upgrade and replacement 
of equipment where appropriate. Net capital 
expenditure, excluding leased assets, of 
£73.6m	(2022:	£73.5m)	was	net	of	proceeds	
from the sale of equipment of £20.9m (2022: 
£8.2m). The asset replacement ratio, which is 
calculated by dividing gross capital expenditure, 
excluding sales proceeds on disposal of items of 
property, plant and equipment and those assets 
capitalised	under	IFRS	16,	by	the	depreciation	
charge on owned property, plant and equipment, 
was 115% (2022: 115%). 

Acquisitions and transactions  
with non-controlling interests
The Group purchased a 35% interest in 
the shares of our Saudi Arabian subsidiary, 
Keller Turki Company Limited, increasing our 
ownership interest to 100%. An initial cash 
consideration	of	£6.4m	was	paid	to	the	non-
controlling shareholders and a contingent 
consideration has been agreed which is valued 
at £9.3m	at	the	balance	sheet	date.	

The accounting for the acquisition of Nordwest 
Fundamentering	in	2022	was	finalised	in	the	
year, giving rise to prior period measurement 
adjustments which are set out in note 5 to the 
consolidated	financial	statements.	In	2022,	
outflows	for	acquisitions,	net	of	cash	and	debt	
acquired, included £3.2m for GKM Consultants 
Inc	and	£6.8m	for	Nordwest	Fundamentering.	
Deferred and contingent consideration in 
respect of prior period acquisitions of £0.2m 
(2022:	£12.4m)	was	paid	in	the	year.

Financing facilities and net debt
The Group’s total net debt of £237.3m (2022: 
£298.9m) comprises loans and borrowings of 
£297.1m (2022: £319.0m), lease liabilities of 
£91.6m	(2022:	£81.0m)	net	of	cash	and	cash	
equivalents	of	£151.4m	(2022:	£101.1m).	The	
Group’s term debt and committed facilities 
principally comprises US private placement 
notes	repayable	in	December	2024	($75m),	
in August 2030 ($120m) and in August 
2033 ($180m) and a £375m multi-currency 
syndicated revolving credit facility, which matures 
in November 2025. At the year end, the Group 
had undrawn committed and uncommitted 
borrowing	facilities	totalling	£425.2m	(2022:	
£273.7m). 

The	most	significant	covenants	in	respect	of	
the main borrowing facilities relate to the ratio 
of net debt to underlying EBITDA, underlying 
EBITDA interest cover and the Group’s net 
worth. The covenants are required to be tested 
at the half year and the year end. The Group 
operates comfortably within all of its covenant 
limits. Net debt to underlying EBITDA leverage, 
calculated	excluding	the	impact	of	IFRS	16,	was	
0.6x	(2022:	1.2x),	well	within	the	covenant	limit	
of 3.0x and within the Group’s leverage target 
of between	0.5x-1.5x.	

Calculated on a statutory basis, including the 
impact	of	IFRS	16,	net	debt	to	EBITDA	leverage	
was 0.8x at 31 December 2023 (2022: 1.5x). 
Underlying EBITDA, excluding the impact of 
IFRS	16,	to	net	finance	charges	was	12.3x	(2022:	
15.7x),	well	above	the	limit	of	4.0x.

On	an	IFRS	16	basis,	year-end	gearing,	defined	
as statutory net debt divided by net assets, was 
46%	(2022:	60%).

The average month-end net debt during 2023, 
excluding	IFRS	16	lease	liabilities,	was	£224.8m	
(2022: £252.1m). The Group had no material 
discounting or factoring in place during the year. 
Given the relatively low value and short-term 
nature of the majority of the Group’s projects, 
the level of advance payments is typically 
not	significant,	although	we	have	negotiated	
advance payments on larger projects such 
as NEOM.

At 31 December 2023, the Group had drawn 
upon	uncommitted	overdraft	facilities	of	£2.4m	
(2022:	£6.9m)	and	had	drawn	£199.7m	of	bank	
guarantee	facilities	(2022:	£190.6m).

Provision for pension
The	Group	has	defined	benefit	pension	
arrangements in the UK, Germany and Austria.

The	Group’s	UK	defined	benefit	scheme	is	
closed	to	future	benefit	accrual.	The	most	recent	
actuarial valuation of the UK scheme was as at 5 
April 2023, which recorded the market value of 
the	scheme’s	assets	at	£45.2m	and	the	scheme	
being 98% funded on an ongoing basis. Given 
the funding level, contributions will cease from 
August	2024,	with	a	total	of	£1.7m	to	be	paid	in	
2024.	Contributions	will	be	reviewed	following	
the next triennial actuarial valuation  
to	be	prepared	as	at	5	April	2026.	The	2023	
year-end IAS 19 valuation of the UK scheme 
showed	assets	of	£46.0m,	liabilities	of	£41.8m	
and	a	pre-tax	surplus	of	£4.2m	before	an	IFRIC	
14	adjustment	to	reflect	the	minimum	funding	
requirement for the scheme, which adjusts the 
closing	position	to	a	deficit	of	£1.5m.

In	Germany	and	Austria,	the	defined	benefit	
arrangements only apply to certain employees 
who joined the Group before 1997. The IAS 
19	valuation	of	the	defined	benefit	obligation	
totalled	£12.6m	at	31	December	2023	(2022:	
£13.2m). There are no segregated funds to 
cover	these	defined	benefit	obligations	and	the	
respective liabilities are included on the Group 
balance sheet. 

All other pension arrangements in the Group are 
of	a	defined	contribution	nature.

The Group has a number of end of service 
schemes in the Middle East as required by local 
laws	and	regulations. The	amount	of	benefit	
payable depends on the current salary of the 
employee and the number of years of service. 

These retirement obligations are funded on the 
Group’s balance sheet and obligations are met 
as	and	when	required	by	the	Group. The	IAS	
19	valuation	of	the	defined	benefit	obligation	
totalled	£3.6m	at	31	December	2023	(2022:	
£3.5m).

Currencies
The Group is exposed to both translational 
and, to a lesser extent, transactional foreign 
currency gains and losses through movements 
in foreign exchange rates as a result of its global 
operations. The Group’s primary currency 
exposures are US dollar, Canadian dollar, euro 
and Australian dollar.

As the Group reports in sterling and conducts 
the majority of its business in other currencies, 
movements in exchange rates can result in 
significant	currency	translation	gains	or	losses.	
This	has	an	effect	on	the	primary	statements	
and associated balance sheet metrics, such as 
net debt and working capital.

A large proportion of the Group’s revenues 
are matched with corresponding operating 
costs in the same currency. The impacts of 
transactional foreign exchange gains or losses 
are consequently mitigated and are recognised 
in the period in which they arise.

Treasury policies

Currency risk
The Group faces currency risk principally on 
its net assets, most of which are in currencies 
other than sterling. The Group aims to reduce 
the impact that retranslation of these net assets 
might have on the consolidated balance sheet, 
by matching the currency of its borrowings, 
where possible, with the currency of its assets. 
The majority of the Group’s borrowings are held 
in US dollars.

The	Group	manages	its	currency	flows	to	
minimise transaction exchange risk. Forward 
contracts	and	other	derivative	financial	
instruments	are	used	to	hedge	significant	
individual transactions. The majority of such 
currency	flows	within	the	Group	relate	to	
repatriation	of	profits,	intra-Group	loan	
repayments and any foreign currency cash 
flows	associated	with	acquisitions.	The	Group’s	
treasury risk management is performed at the 
Group’s	head	office.

The	Group	does	not	trade	in	financial	
instruments, nor does it engage in speculative 
derivative transactions.

Interest rate risk
Interest	rate	risk	is	managed	by	mixing	fixed	
and	floating	rate	borrowings	depending	upon	
the	purpose	and	term	of	the	financing.	At	
31 December	2023	the	majority	of	borrowings	
were	fixed	rate.

Credit risk
The	Group’s	principal	financial	assets	are	
trade and other receivables, bank and cash 
balances and a limited number of investments 
and derivatives held to hedge certain Group 
liabilities. These represent the Group’s 
maximum exposure to credit risk in relation 
to financial assets.

The Group recognises impairment losses on 
trade receivables where there is uncertainty over 
the amount we can recover from customers. 
The amount recognised in underlying costs 
of £21.3m (2022:£2.9m) has increased as 
a	result	of	specific	impairments	relating	to	
customers	in	financial	difficulty	or	amounts	
where cash receipts have been delayed due 
to customer disputes.

The Group has procedures to manage 
counterparty risk and the assessment of 
customer credit risk is embedded in the contract 
tendering processes. The counterparty risk on 
bank and cash balances is managed by limiting 
the aggregate amount of exposure to any one 
institution by reference to its credit rating and by 
regular review of these ratings.

Return on capital employed
Return	on	capital	employed	is	defined	at	Group	
level	as	underlying	operating	profit	divided	by	
the accounting value of equity attributable to 
equity holders of the parent plus net debt plus 
retirement	benefit	liabilities.	Return	on	capital	
employed	in	2023	was	22.8%	(2022:	14.9%).

Principal risks and uncertainties

Principal risks  
and uncertainties

Our business is subject to risks and uncertainties and as such we have a risk management 
governance	framework	to	identify,	evaluate,	analyse	and	mitigate	significant	risks,	including	
climate-related	risks	and	opportunities	(CRROs),	to	the	achievement	of	our	strategy. 	 
We have processes that seek to identify risks from both a top-down strategic perspective  
and a bottom-up local operating company perspective.

Risk management governance framework

The risk management process within Keller follows industry best practice, 
incorporating many of the applicable principles of the risk management 
standard ISO 31000:2018 and ways of working from leading risk management 
organisations. The adoption of a consistent risk management process within a 
comprehensive	framework	can	help	to	ensure	that	risk	is	managed	effectively,	
efficiently	and	coherently	across	Keller.

Effective	risk	management	protects	and	
adds value to Keller and its stakeholders 
and supports Keller’s objectives by:

•  providing a framework that enables future risk 

• 

management activity to take place in a consistent 
and controlled manner;
improving decision making, planning and 
prioritisation by comprehensive and structured 
understanding of the business activity, volatility 
and project opportunity/threat;

•  contributing	to	a	more	efficient	use/allocation	of	
capital and resources within the organisation;
•  reducing volatility in the non-essential areas of 

the business;

•  protecting and enhancing assets and company 

image;

•  developing and supporting Keller’s people and 

knowledge base; and

•  optimising	operational	efficiency.

Important developments in 2023

Key areas of focus for 2024

•  We will continue to focus on deepening the understanding and use 

of our risk management data consistently across the Group through 
the use of our new risk management platform, targeted training and 
business unit level risk workshops. 

•  We will provide dedicated, targeted training on the use of the new 

GRC	tool	in	the	first	half	of	2024	to	ensure	a	consistent	methodology	
is used when identifying, assessing, managing and reporting on risks. 
These changes will lead to continued improvement and consistency of 
risk reporting and in turn support knowledge sharing across business 
units and a timely and robust decision-making process.

•  We will perform a review of our risk appetite aligned to the key risk 

categories against which we identify, assess, manage and report on. 
Any agreed changes will be updated in the new GRC tool. 

•  We will continue to focus on strengthening our assurance activity, 
especially in the second line of defence, which will be adequately 
resourced	to	ensure	our	first	line	internal	control	environment	is	
operating	effectively.	

•  We will continue to further develop and widen the scope of the CRROs 
scenario analysis tools, in line with the recommendations of the Task 
Force on Climate-related Financial Disclosures (TCFD). 

The continued strengthening of our risk management framework remained 
a key priority for 2023, as understanding current and emerging risks is 
central	to	effective	decision	making	in	Keller,	aligned	to	our	four	strategic	
levers and in line with the Group’s risk appetite. Risks that the Group 
remains exposed to from day-to-day delivery of projects and the longer-
term pursuit of its strategic objectives continue to be assessed, managed 
and monitored as depicted in the process above.

During the year we undertook several initiatives to support this:

•  Continued to strengthen our internal control environment, measured 
against a comprehensive set of Group Finance Standards across 
a	number	of	disciplines	including	financial	reporting,	accounting,	
operational management, taxation and treasury, reinforcing a 
culture of strong governance and risk management. This has been 
independently validated through both management review and the 
internal audit programme.

•  Following	the	financial	reporting	fraud	in	the	Austral	Business	

Unit discovered in December 2022, a controls response plan was 
developed and executed that covered both the control failings in 
Austral that enabled this fraud to occur and also a wider review of 
controls across Keller. Enhancing our assurance capability in the 
second	line	of	defence	will	remain	a	key	area	of	focus	in	2024,	along	
with further improvements in project performance management.
•  Successfully deployed our new Governance, Risk and Compliance 
(GRC)	tool	in	Q4	2023,	which	will	further	enhance	our	capability	
to manage, monitor and report on our internal control and risk 
management environment. 

•  Continued to improve the quality of data on risk reporting across the 
Group, including climate-related risks and opportunities, through 
regular robust and engaging management reviews of risk throughout 
the organisation.

Our risk appetite
The Group’s risk appetite drives high standards of health, safety and 
environmental compliance, and a focus on commercial risks and 
opportunities. This approach is fully understood across the organisation, 
allowing	us	to	collectively	build	a	profitable	and	leading	market	share	whilst	
limiting the Group’s risk exposures to an acceptable level. This level of risk is 
considered appropriate for Keller to accept in achieving strategic objectives.

Risk identification and impact
The Group’s principal risks are analysed on an inherent (pre-mitigation) and 
residual (post-mitigation) basis.

Risk trends
The ongoing review of the Group’s principal risks focuses on how these 
risks may evolve as well as a consideration of emerging and climate-
related	risks,	which	we	identified	and	impact-assessed	over	the	short	term	
(ie the next	year),	medium	term	(ie	two	to	five	years)	and	long	term	(ie	six	
to 30 years). As such, horizon scanning and reviewing emerging potential 
legislation forms key elements of the risk review process.  

These elements are embedded within the Group’s day-to-day 
management of risk and its current risk reporting processes. The Audit 
and Risk Committee and the Board reviewed the Group’s principal risks 
and uncertainties at their meetings in July 2023 and December 2023. 
Keller’s	operational	and	financial	performance	in	a	tougher	macroeconomic	
environment during 2023 was very encouraging and our principal risks and 
uncertainties have not changed materially since the publication of last year’s 
annual report. However, macroeconomic challenges continue to impact our 
markets,	including	the	continued	expectation	of	increased	inflation,	higher	
interests rates and continued political instability in key regions where Keller 
operates. The following principal risks will continue to be closely monitored 
throughout	2024:

•  supply chain;
•  a rapid downturn in our markets; and 
• 

failure to procure new contracts on satisfactory terms. 

Information on these and the Group’s other principal risks is set out from 
page	40 onwards.

Developing the viability statement 
In developing the viability statement, it was determined that a three-
year period should be used, consistent with the period of the Group’s 
business	planning	processes	and	reflecting	a	reasonable	approximation	
of the maximum time taken from procuring a project to completion. 
Management reviewed the principal risks and considered which of 
these risks might threaten the Group’s viability. It was determined that 
none of the individual risks would in isolation compromise the Group’s 
viability,	and	so	a	number	of	different	severe	but	plausible	principal	risk	
combinations were considered. A downside sensitivity analysis, as well 
as a consideration of any mitigating actions available to the Group, was 
applied	to	the	Group’s	three-year	cash	flows	forecasted	as	part	of	the	
business planning process and presented to the Board for discussion, 
further to review by the Audit and Risk Committee. The Board discussed 
the process undertaken by management, and also reviewed the results 
of stress testing performed to ensure that the sensitivity analysis was 
sufficiently	rigorous.	The	Board	also	carried	out	a	robust	assessment	of	
the principal risks facing the Group, including those that would threaten 
its business model, future performance, solvency or liquidity.

Viability statement 
In accordance with provision 31 of the UK Corporate Governance Code, 
the Directors have assessed the prospects of the Group over a three-
year period. 

The Board selected the three-year period as: 

• 

• 

the Group’s business planning and budget processes are carried out 
over a three-year period which provides the relevant estimates; and 
three years is a reasonable approximation of the maximum time 
taken	from	procuring	a	project	to	completion	and	therefore	reflects	
our current revenue earning cycle. 

The Group’s term debt and committed facilities principally comprises US 
private	placement	notes	repayable	in	December	2024	($75m),	in	August	
2030 ($120m) and in August 2033 ($180m).

The Group also has a £375m syndicated revolving credit facility which 
is due to expire in November 2025. The assessment assumes that 
the Group will continue to have access to this funding throughout the 
viability period on the basis that the Group will either renew the facility 
or	have	sufficient	time	to	agree	an	alternative	source	of	finance	on	
comparable terms.

The	review	included	cash	flows	and	other	key	financial	ratios	over	the	
three-year period. These metrics were subject to sensitivity analysis 
which	involves	flexing	a	number	of	the	main	assumptions	underlying	
the forecast both individually and in collectively. Downside sensitivity 
analysis was carried out to evaluate the potential impact on the Group of 
a global downturn in the construction/geotechnical market. Revenues in 
2025	and	2026	were	assumed	to	decrease	by	10%	year	on	year	with	an	
operating margin deterioration in proportion.

A number of other downside risks were also modelled including 
worsening	working	capital	performance,	inability	to	finance	the	Group’s	
business and unforeseen settlements. The Directors’ assessment has 
been made with reference to the Group’s current position and prospects, 
the Group’s strategy, the Board’s risk appetite and the Group’s principal 
risks and how these are managed, as detailed in the Strategic report. 

On the basis of the above and other matters considered and reviewed 
by the Board during the year, the Board has reasonable expectations 
that the Group will be able to continue in operation and meet its liabilities 
as they fall due over the next three years. In doing so, it is recognised 
that such future assessments are subject to a level of uncertainty 
that increases with time and, therefore, future outcomes cannot be 
guaranteed or predicted with certainty.

Going concern 
The Group’s business activities, together with the factors likely to 
affect	its	future	development,	performance	and	position,	are	set	out	
in	the	Strategic	report.	The	financial	position	of	the	Group,	its	cash	
flows	and	liquidity	position	are	described	in	the	Chief	Financial	Officer’s	
review, with details of the Group’s treasury activities, long-term funding 
arrangements	and	exposure	to	financial	risk	included	in	note 25 to the 
consolidated	financial	statements.	

The	Group	has	sufficient	financial	resources	which,	together	with	
internally	generated	cash	flows,	will	continue	to	provide	sufficient	
sources of liquidity to fund its current operations, including its contractual 
and commercial commitments and any proposed dividends. The 
Group is therefore well placed to manage its business risks. After 
making enquiries, the Directors have formed the judgement at the 
time	of	approving	the	financial	statements,	that	there	is	a	reasonable	
expectation that the Group has adequate resources to continue in 
operational existence for the period through to 31 March 2025. For this 
reason, they continue to adopt the going concern basis of accounting in 
preparing	the	financial	statements.

in 2030 and $180m maturing in 2033. There is 
$75m	of	US	private	placement	maturing	in	2024.	

•  The	Group	maintains	significant	undrawn

•  Embedded	procedures	to	monitor	the	effective	
management of cash and debt, including weekly 
cash	reports	and	regular	cash	flow	forecasting	to	
ensure compliance with borrowing limits and 
lender covenants.

•  Culture focused on actively managing our 

working capital and monitoring external factors 
that	may	affect	funding	availability.

New $300m US private 
placement secured, along 
with strong operational 
performance throughout 
2023, demonstrate clear 
ability to manage both 
existing and future risks.

contract. 

•  A focus on understanding customer 

requirements and competitor capabilities.
•  Structured bid review processes in operation 

throughout	the	Group	with	well-defined	
selection criteria that are designed to ensure we 
take on contracts only where we understand and 
can manage the risks involved.

•  The Project Lifecycle Management (PLM) 

Standard has introduced more rigour into how 
risks are considered during the opportunity, 
contract approval and project execution phases.

•  Sales training – focus on contractual and 

commercial terms.

•  Continuous monitoring of market trends and 

their potential impact.

•  Continuous monitoring of order book wins and 

losses.

We continue to maintain a 
strong order book with 
improving margins during 
2023. We are also seeing 
increased competition on 
contracts within our 
markets with increased 
pressure on bid pricing 
from our customers that 
along	with	inflationary	
pressures could 
potentially erode contract 
margins.	Significant	
increase in the cost of 
insurance along with 
increased self-insured and 
deductible limits will 
require a renewed 
communication across 
Keller with a focus on 
minimising our exposure 
to unnecessary risk and 
contractually limiting our 
liability wherever possible.

Work to refresh and 
refocus the PLM Standard 
focusing on project 
performance 
management, hence 
renaming it PPM (Project 
Performance 
Management), is almost 
complete.

Mitigation and internal controls

Movement since 2022

Keller	operates	in	many	different	
jurisdictions and is subject to 
various rules, regulations and 
other legal requirements 
including those related to 
anti-bribery and anti-corruption. 
Failure to comply with the Code 
of Business Conduct or other 
regulations could leave the 
Group exposed to:

• 

Instances of bribery and 
corruption.

•  Fraud and deception.
•  Human rights abuses, such as 
modern slavery, child labour 
abuses	and	human	trafficking.
•  Unfair competition practices.
•  Unethical treatment within 

our supply chain.

These failures could result in 
legal investigations, leading to 
fines	and	penalties,	reputational	
damage and business losses.

Failure to comply with 
the Code of Business 
Conduct or related 
policies and procedures 
could stem from:

•  Failure to establish 
robust corporate 
culture.

•  Failure to adopt a 
compliance risk 
approach.

•  Failure to embed the 
Group’s values and 
behaviours across 
the entire 
organisation, 
including any joint 
ventures.

•  Failure to have a 

robust training and 
monitoring 
programme in place.

•  Deliberate non-
compliance.

•  A Code of Business Conduct that sets out 
minimum expectations for all colleagues in 
respect of ethics, integrity and regulatory 
requirements, that is updated annually and is 
backed by a training programme to ensure that it 
is fully embedded across the Group.

•  Ethics	and	Compliance	Officers	in	every	business	

unit who support the ethics and compliance 
culture and ensure best practice developed by 
the Group is communicated and embedded into 
local business practices.

•  Regular workshops across the Group to ensure 
compliance	risks	are	identified	and	addressed.
•  Ethics and compliance updates to the Audit and 

Risk Committee semi-annually.

•  An independent third-party whistleblowing 

helpline that is actively promoted. Complaints 
are independently investigated by the 
Compliance and Internal Audit teams and 
appropriate action taken where necessary.

Following on from the 
financial	reporting	fraud	
in the Austral business 
discovered in late 2022, a 
specific	controls	
response plan was 
developed and executed 
in 2023. This plan covered 
the	specific	control	
failings in Austral and a 
wider review across Keller. 
All elements of the plan 
are either completed or 
progressing well and 
owned by a senior leader 
in the business.

Keller has a history of innovation 
that has given us a technological 
advantage which is recognised 
by our clients and competitors. 
Failure to maintain this 
advantage through the 
continued technological 
advancements in our 
equipment, products and 
solutions may:

• 

Impact our position in the 
market.

•  Result in us not being 

selected for key complex, 
high-value projects that 
support the Group strategy.

•  Make	it	more	difficult	to

Causes

Mitigation and internal controls

Movement since 2022

Inability to successfully deliver 
projects in line with the agreed 
customer requirements may 
result in:

• 

•  Cost overruns, contractual 
disputes and reputational 
damage.
Ineffective	project	delivery	
may also expose the Group to 
long-term obligations 
including legal action and 
additional costs to remedy 
solution failure.

•  Failure to manage our 
projects to ensure 
that they are delivered 
on time and to budget 
due to unforeseen 
ground and site 
conditions, weather-
related delays, 
unavailability of key 
materials, workforce 
shortages or 
equipment 
breakdowns.

•  Lack of 

comprehensive 
understanding of 
contract obligations.
Inadequate resources 
(people, physical 
assets and materials).

• 

•  Ensuring we understand all of our risks through 
the bid appraisal process and applying rigorous 
policies and processes to manage and monitor 
contract performance.

•  Ensuring we have high-quality people delivering 
projects. Keller’s Project Management Academy 
and Field Leadership Academy are designed to 
create project managers with a consistent skill 
set across the entire organisation. The 
academies cover a broad range of topics 
including contract management, planning, risk 
assessment, change management, decision-
making	and	finance.

•  Safety Standards for operations (eg platform, 

cage	handling),	Equipment	Standards	and	fleet	
renewal.

•  The PLM Standard aims to drive a consistent 

approach to project delivery with robust controls 
at every project phase. This is currently being 
updated and will be renamed PPM (project 
performance management). Alongside the 
updated standard will be an app to support the 
efficient	and	effective	execution	of	projects.
•  A formal, structured approach to Lean and 5S is 
being rolled out across the organisation, which is 
improving processes and strengthening Keller’s 
working culture.

The number of projects 
not executed to 
expectation in 2022 was 
above the long-term 
average, adversely 
impacted by persistently 
high	inflation	across	
North America and 
Europe.

This trend has improved 
throughout 2023 along 
with the work under way 
to update the PLM 
Standard focusing on 
project performance 
management. This will 
put in place better 
controls to ensure 
continued	effective	
execution of projects 
across Keller.

10    Supply chain – partners fail to meet the Group’s operational expectation and contractual obligations (including 

capacity, competency, quality, financial stability, safety, environmental, social and ethical) 

Description and impact

Causes

Mitigation and internal controls

Movement since 2022

•  The Group has developed long-term 

partnerships with key suppliers, working closely 
with them to understand their operations, but is 
not over-reliant on any single one, with an 
extensive network of approved suppliers in place 
across the organisation to support its strategic 
ambitions.

•  A Supply Chain Code of Business Conduct that 
sets out minimum expectations for all suppliers 
in respect of ethics, integrity and regulatory 
requirements, that is updated annually.

•  Working group established, reporting to the 

Group Company Secretary and Legal Advisor, to 
drive minimum standards, both contractually and 
behaviourally, across key labour suppliers.

Failure to manage suppliers 
effectively	could	lead	to:

•  Delays to executing projects 
waiting for materials and 
ongoing business disruption.

•  Additional	costs	to	find	
alternative suppliers.

•  Becoming involved in legal 

disputes	and	potentially	fines	
and penalties.

•  Damaging our reputation and 
potentially being barred from 
bidding on future contracts.
•  Human rights abuses, such as 
modern slavery, child labour 
abuses	and	human	trafficking.

• 

•  Failure to embed the 
Group’s expectation 
within the 
procurement process.
Inadequate 
assessment of supply 
chain partner 
capabilities during 
bidding phase.
•  Lack of supplier 

resilience due to rising 
costs of energy as a 
result of geopolitical 
uncertainty.
•  Lack of supply 

availability due to 
increased demand 
from and too little 
supply.
Inflation	driving	up	
prices.

• 

•  Logistical impact 

causing delays due to 
lack	of	HGV	drivers.

Supply chain issues, 
especially availability of 
certain materials (steel, 
cement and energy) 
continue to show signs of 
easing. Pricing is still 
adversely impacted by the 
persistently	high	inflation,	
but this too is beginning to 
show signs of abating.

While pressure remains as 
a result of the geopolitical 
uncertainty, it is being 
better managed as 
demand cools slightly as 
interest rate increases 
take	effect	on	some	
investment decisions.

In 2023 we carried out an 
independent legal 
assessment of our human 
rights and modern slavery 
standards and processes. 
Consequently, we have 
introduced a Human 
Rights Policy, updated our 
Supply Chain Code of 
Business Conduct and 
supplier contractual 
clauses and put in place 
more rigorous due 
diligence processes 
across our supply chain.

pressure on competition 
for skilled personnel is still 
an issue in some parts of 
the Group. However, job

should ease this issue. 
Focus remains on

Task Force on  
Climate-related  
Financial Disclosures

Keller has considered the risks and opportunities posed to the business by climate change, 
and the impacts it may face over several time horizons. The following statement discloses 
Keller’s	climate-related	financial	information	and	actions	the	business	is	taking	to	respond	
to climate change. It is consistent with the recommendations of the Task Force on Climate-
related	Financial	Disclosures	(TCFD)	in	compliance	with	Listing	Rule	9.8.6R,	with	areas	where	
disclosures are only partially consistent included at the end of the statement on page 58.

Governance

 Board oversight of climate-related risks and opportunities

The Board is ultimately responsible for the oversight of climate-related 
risks and responsibilities, and for ensuring that the Group’s approach 
to sustainability is implemented across the business. The Group’s 
governance framework is structured to provide regular and relevant 
updates to the Board in order to support informed decisions on climate-
related matters. The governance framework is outlined in full on page	36, 
and the organisational and reporting structure for climate governance is 
depicted on page	49.

ESG, including the management of climate-related issues, was a 
listed topic on the agenda at four Board meetings in the last year, 
corresponding to the ESG Board Report which is delivered to the Board 
on a quarterly basis. The report is coordinated by the Group Company 
Secretary and Legal Advisor’s team, and ensures a clear reporting line 
on all ESG matters, including climate risk, to the Board and the Group 
Chairman, who is the designated Director for ESG and sustainability 
matters. Additional discussions on sustainability-related matters also 
take place as required. 

The Sustainability Committee, a Main Board Committee, has oversight 
of the Board’s responsibilities in relation to environmental matters, 
including climate-related matters. In line with its terms of reference, 
this committee convenes a minimum of three times a year and is 
comprised of the CEO, the Group Chairman and the independent 
Non-executive Directors (NEDs). Its report for 2023 can be found 
on page 105. The Sustainability Committee was formed in May 
2023 following the merger of the Environment and the Social and 
Community Committees. It is chaired by Juan G. Hernández Abrams, 
an independent NED on the Board.

The Sustainability Steering Committee, the Main Management 
Committee responsible for climate-related and environmental matters 
alongside other ESG topics, is composed of representatives from each 
division – North America, Europe, and AMEA – and the Group’s relevant 
functions, as listed on the organisational and reporting structure for 
climate governance on page	49. The Committee convenes quarterly 
and reports to the Sustainability Committee and to the Executive 
Committee, which is also Main Management Committee. As part 
of the risk management process for climate risks, the Sustainability 
Steering Committee is responsible for identifying climate-related risks 
and reporting these to the Audit and Risk Committee, a Main Board 
Committee, which in turn reports to the Board. The Sustainability 
Steering Committee is chaired by the Engineering and Operations 

Director, who is head of sustainability and responsible for having 
oversight on sustainability matters. More detail on the risk management 
process for climate-related risks is given in the Risk Management section 
of this statement and in the Principal Risks and Uncertainties section 
(page	36).

As part of the risk management process for climate risks, the

ESG matters, including climate-related issues, are taken into account 
in core strategic decisions by the Board and management via a formal 
Project Review process. This process incorporates assessment of the 
viability of projects on the grounds of safety and legal compliance. The 
Group is continuing to develop a stage of this process which would also 
incorporate assessment of project viability on the grounds of climate-
related impact. Currently, we incorporate an assessment of projects 
based	on	the	financial	impact	that	would	be	had	as	a	consequence	of	
an adverse	reputational	event.

As a result of this process of incorporating climate-related issues into 
core strategic decisions, during 2023 we adapted our rig procurement 
and development strategy to protect our equipment from future 
transition risks. We set aside a £100,000 budget to help business units 
trial	biofuels,	including	hydrotreated	vegetable	oil	(HVO),	so	that	these	
fuels	can	be	offered	to	clients	with	sustainability	requirements.	As	part	of	
this	strategy,	we	also	invested	in	our	first	large	electric	rig	as	part	of	our	
rolling rig development programme. Electric rigs are safeguarded against 
future air quality legislation, meaning they can continue to be used 
without risk of becoming stranded assets.

The Board monitors and oversees progress against goals and targets for 
addressing climate-related issues principally through the Sustainability 
Committee, and also through the Remuneration Committee where 
there is an impact on executive remuneration. More detail on ESG-linked 
remuneration can be found on page 120.

The Sustainability Steering Committee allows divisions and functions 
to raise sustainability challenges, including on climate-related topics, 
to the Executive Committee and to the Board and its committees. 
It	also	acts	as	a	forum	for	different	areas	of	the	business	to	convene	
and discuss sustainability strategy, and for sharing sustainability best 
practice between divisions. The Committee is responsible for integrating 
sustainability targets and measures into the Group business plan, in 
order to successfully drive changes important to the company.

Each division of the business has a ‘Team Planet’, a group responsible 
for climate-related issues. These teams are composed of multiple 
representatives from diverse roles across each division, from design 
and procurement through to operations, and each includes at least 
one representative	from	each	business	unit.	

Each Team Planet works alongside the Group’s HSEQ teams and 
those responsible for local climate risk registers to help bring climate-
related risks and opportunities (CRROs) and associated issues to the 
attention of management so that they can be acted on. For example, 
Team Planet are critical in grounding our climate scenario modelling in 
the actual contractual and practical landscape of our projects. We used 
multiple Team Planet North America members to both create and then 
sense-check the days’ delay from various extreme weather events in our 
scenario analysis.

Keller Group plc  Annual Report and Accounts 2023

Strategy

The long-term success of the Group’s business depends on actively 
assessing, analysing and managing the potential impacts of climate-
related risks, and adapting our operations to take advantage of 
opportunities, in order to create a strong position in the transition to a 
low-carbon economy. 

As a business which provides a wide variety of services across multiple 
geographies, Keller is exposed to a variety of impacts from climate 
change	across	the	short,	medium	and	long	term.	Across	different	
potential	climate	scenarios,	different	areas	of	the	business	face	more	
pronounced physical risks as a consequence of global temperature rise 
and extreme weather events, increased transition risks from regulation, 
and	transition	opportunities	afforded	by	the	requirement	for	lower-
carbon solutions and climate adaptation.

To navigate our CRROs, and to ensure that business units are best 
equipped to lead and deliver appropriate climate mitigation, we have 
developed an internal climate-related risk register owned at the business 
unit level. CRROs are evaluated at the business unit level and fed back 
to the Group, where a consolidated view on their relative severity is 
produced. Details on each of these CRROs and Keller’s management 
of them is provided in detail in the table on pages	54	to	56. In 2023, we 
expanded the scope and depth of our quantitative climate scenario 
analysis, which produced more advanced insights into the impacts of 
climate change on our business. Details on how we conducted scenario 
analysis are provided overleaf. 

Based on the outputs of our climate-related risk register, and from 
scenario analysis, even the climate-related risks which are judged to pose 
the greatest risk are not deemed material to the business. However, 
taken	together,	climate-related	risks	are	judged	to	represent	a	significant	
risk, and climate change is therefore considered a principal risk to the 
business.	In	order	to	reflect	this	in	our	financial	planning,	climate-related	
risk is built into the viability statement sensitivity analysis, which looks 
out over a three-year period. The full viability statement can be found 
on page 39. 

Time	horizons	for	the	impacts	of	CRROs	have	been	defined	as	follows:

•  Short term:  
•  Medium term:  
•  Long	term:		

1 year
2–5 years 
6–30	years	

These divisions take into consideration both business cycles and the 
long-term time horizons relevant to physical climate risk. The short-
term	risk	is	defined	as	one	year	in	recognition	of	the	short-term	nature	
of the majority of our projects, which are typically bid for, won and 
executed within one year. The medium term aligns with the business 
planning horizons used for the viability statement. The long term 
aligns to publicly available climate projections, which extend to 2050, 
and which provided the time range for our scenario analysis. These 
timeframes are also recognised by CDP as consistent with current 
best practices	for	TCFD	disclosures.	

Scenario analysis 
In 2023, we advanced our quantitative scenario analysis in order to 
better evaluate the Group’s CRROs. We built on our analysis from 
2022, and included new CRROs, a wider geographical scope, and more 
sophisticated modelling of our risks. 

As the impact on the Group from CRROs varies greatly across our 
different	geographies,	we	have	focused	analysis	on	areas	where	the	
relevant risks were most severe, as determined by our qualitative 
assessment. Physical risk was modelled for our North America (NA) 
and Australian divisions, and transition risk was modelled for our 
Europe Division.	

As we currently face more impacts from weather events in NA and 
Australia than we do in Europe, we chose to focus our physical analysis 
initially on these regions. Conversely, since regulations on carbon and 
emissions are currently at a more advanced stage in Europe than in NA 
and AMEA, we chose to focus our transition analysis initially on Europe. 

Our scenario analysis modelling has been established in a way that is 
replicable annually, so that the Group can see how impacts are changing 
on an ongoing basis. As the sophistication of climate science, availability 
of data, and clarity around regulation all increase, we expect to enhance 
the completeness and accuracy of our scenario analysis. We also expect 
future analysis to be able to inform in greater detail our strategies for 
mitigating risk and capturing opportunity, and to help us know where our 
efforts	should	be	focused	when	addressing	CRROs.

Scenario analysis continued
In 2022, we assessed the risk of the increased cost of raw materials, and the accompanying opportunity for low-carbon solutions, in the pilot location 
of Austria. This year, a new transition risk has been addressed, regulation of existing products and services, which has been addressed by modelling the 
risk of stranded rig assets in Europe as a result of incoming regulation. Physical risk modelling was expanded to the entire North America (NA) Division 
and	Australia,	with	the	scope	of	weather	perils	expanded	from	hurricanes	to	also	include	precipitation,	extreme	heat	and	wildfires.

Strategy

Scenario analysis: Physical risk

NA and Australia

Risk: Impact on projects from hurricanes, precipitation, heat and wildfires 

Selection
Impact	from	acute	weather	risks	is	identified	as	a	medium	risk	across	our	
three	divisions,	with	chronic	risks	being	identified	as	a	high	risk	for	our	NA	
and AMEA divisions. The Group already experiences impacts to projects 
as a result of extreme weather in these locations.

Approach
We are impacted by weather through disruptions to our projects, which 
cause days of delay and repair costs. We made assumptions around 
the days of operational disruption and associated costs from each 
event	type,	and	then	used	these	figures	to	model	revenue	impact.	For	
hurricanes, we used existing hurricane models applied to an earth climate 
model, and then assumed a radius of impact from forecasted hurricanes. 
For	extreme	heat,	we	modelled	disrupted	days	at	35–40°C	and	40°C+.	
For	precipitation,	20–50mm	days	and	>50mm	days.	For	wildfire,	we	
modelled	high	fire	weather	index	(FWI)	days	as	representative	of	an	
average	likelihood	of	wildfires.	

Climate scenarios were informed by the IPCC’s Representative 
Concentration Pathways (RCPs). Both scenarios were assessed out 
to 2050.	

Assumptions
• 

Impacts to future projects were modelled using current project 
locations. This assumes that the general locations of our operations 
will not change greatly. 

•  The	financial	impact	from	lost	workdays	was	modelled	using	an	

average days’ delay from each weather event, and average repair 
costs following events. 

Results 
The Group faces limited exposure to climate-related physical risk. The 
total	potential	financial	impact	of	all	combined	physical	risks	is	set	to	
be c5% of projected total revenue in 2050, on average between the 
modelled	scenarios.	This	is	an	unabated	figure,	which	assumes	that	the	
Group takes no action to address these risks. Extreme heat has emerged 
as	the	greatest	risk	of	the	four	modelled,	accounting	for	46%	of	the	total	
predicted revenue impact, and Florida stands out as the state facing 
the greatest impact, given its high revenue generation and its current 
exposure to climate risks. 

Response
In order to better quantify and control our impacts from extreme 
weather, we will aim to track actual days’ delay across operational sites, 
and improve our systems for collecting costs from delays and mitigating 
activities. We will be reassessing our health and safety policies for heat, 
particularly	in	more	highly	affected	regions	such	as	Florida,	in	order	to	
set clearer limits on when work can continue and when to delay, and 
to	provide	greater	understanding	of	what	potential	future	financial	
impacts are.	

We will reassess our contracting terms in order to implement 
greater consistency around the liability which the Group takes for 
weather impacts.

Selection
As	our	rigs,	which	are	defined	as	NRMMs,	emit	greenhouse	gases	and	
particulates, they may in future be subject to regulation which prevents 
their usage unless they are below a certain requirement for emissions, or 
are zero emissions (ie electric). The Group already faces some limitations 
on higher-emissions rigs being used in certain projects in cities in Europe.

Therefore,	a	fourth	scenario	was	created,	titled	‘London	Electrification’,	
which was based on London’s more stringent rules for NRMMs. London 
is	one	of	the	few	cities	in	Europe	with	a	specific	policy	around	the	
phasing-out of high-emission NRMMs. In accordance with London policy, 
this scenario assumed that only zero emission machinery (ie electric rigs) 
will	be	allowed	by	2040.	

Impacts	from	this	risk	are	identified	as	medium	in	Europe	and	NA,	and	low	
in AMEA.

Approach
IEA	scenarios	were	each	taken	to	represent	a	different	speed	of	phase-
out of rigs, which were informed by emissions reduction trajectories from 
the IEA’s World Energy Outlook 2023, using the ‘Heavy duty vehicles’ 
pathway as an approximation for NRMMs. The EU has also instated 
regulation	which	defines	emission	limits	for	NRMM	engines	which	can	be	
sold	in	the	EU.	While	this	does	not	directly	affect	rigs	which	can	be	used,	
this regulation informed our approach. 

These	scenarios	(NZE,	APS,	and	STEPS)	were	used	to	define	when	rigs	
of	different	emission	stages	in	our	fleet	would	become	stranded	assets.	
Assumptions were also applied to each scenario about the rate at which 
Keller	would	transition	its	fleet	to	lower-emission	and	electric	rigs.	The	
speed of the assumed transition was correlated to the stringency of the 
scenario,	with	less	rapid	fleet	transitions	assumed	for	warmer	scenarios	
with less stringent regulation. 

However, as the IEA’s pathways take a global perspective, they were 
ultimately less ambitious than what we expect for Europe. We found 
that	no	financial	impacts	were	observed	for	even	the	most	stringent	
scenario, NZE. 

Assumptions
•  An average lifespan was assumed for rigs, after which they would be 
replaced with a newly purchased rig. Depending on the scenario, the 
new rigs purchased were categorised as electric and/or the most 
efficient	engine	type.	

•  The IEA’s heavy-duty transport emissions reductions trajectory was 

used to inform emissions reductions for NRMMs.

Results
The Group is unlikely to face stranded rig assets in Europe in any of the 
IEA	scenarios.	In	these	scenarios,	the	rate	at	which	older	rigs	in	the	fleet	
are replaced with lower and zero-emissions rigs means that by the time 
regulations	come	into	force,	Keller’s	fleet	is	already	compliant.	

However,	in	the	London	Electrification	scenario,	Keller	will	have	to	impair	
rigs	in	its	fleet	equivalent	to	2.8%	of	the	net	book	value	of	the	fleet,	
by	2040.	This	is	the	strictest	scenario,	and	we	believe	it	is	unlikely	that	
regulations equivalent to the strictness of London’s NRMM regulations 
will be applied across Europe. We therefore consider the likelihood of the 
London	Electrification	scenario	to	be	low,	and	for	the	risk	of	it	occurring	
to therefore be minimal. However, it may be the case that similar 
restrictions are applied in urban areas in Europe, where many of our 
projects are located. 

Response
We will incorporate emissions and regulation considerations into our 
capex plan for future rig purchases, informed by potential timelines for 
regulation. This plan will aim to support the replacement of older rigs with 
lower and zero-emissions rigs, so that these have been replaced by when 
regulations	come	into	effect.	

Our rig decarbonisation strategy, which involves us trialling and 
implementing alternative equipment in our projects, helps us to address 
potential future requirements. In 2023, we trialled electric rigs for the 
first	time,	and	aim	to	expand	our	use	of	this	zero-emission	equipment	
in the future. Already, all the rigs we produced in 2022 were electric, 
electrohydraulic, or had ‘stage 5’ engines, the lowest emissions tier. 
Further information on our actions can be found in the table of our 
CRROs on page	54. More detail on our decarbonisation strategy can 
be found	on	page	63.

Strategy

Keller’s CRROs and strategic responses

Austria

Risk: Cost of raw materials 

Opportunity: Low-carbon solutions
For details on these CRROs and the approach taken, please refer to Keller’s 2022 Annual Report and Accounts. 

Results
The risk associated with the cost of raw materials, and the accompanying opportunity of the potential for low carbon solutions, are likely to impact 
the	Group	most	significantly	in	the	NZE	scenario.	This	is	mainly	driven	by	greater	stringency	of	climate	regulation,	including	carbon	pricing.	Outputs	
showed	that	exposure	to	elevated	carbon	pricing	is	not	entirely	offset	by	the	decarbonisation	rate	of	materials,	even	in	an	NZE	scenario.	However,	the	
direct	financial	impact	arising	from	this	is	likely	to	be	minimal,	given	that	the	cost	of	materials	is	embedded	into	the	contracting	process.	In	addition	to	
risk,	opportunities	were	also	highlighted,	including	Keller’s	ability	to	offer	lower	carbon	solutions	to	clients	for	equivalent	services.	The	findings	around	
indirect	financial	impacts	and	opportunities	will	apply	to	all	other	European	locations	since	the	regulatory	frameworks	are	the	same.	For	other	business	
units such as the UK, the impacts will be very similar to Europe’s, due to legislative equivalences.

Response
We	will	continue	to	test	where	low-carbon	product	lines	are	feasible	within	our	service	offerings,	and	continue	to	test	the	use	of	low-carbon	materials	
within existing product lines.

We	are	training	all	engineers	in	the	use	of	the	sector	standard	carbon	calculator	to	enable	them	to	determine	and	offer	low-carbon	solutions.	This	
carbon	calculator	has	been	embedded	into	our	estimating	spreadsheets	in	key	markets,	enabling	us	to	demonstrate	the	carbon	savings	of	different	
solutions to clients.

In 2023, we held a low-carbon cement workshop with representatives from across the Group. As an outcome, we outlined short, medium and long-
term	actions	needed	to	help	decarbonise	our	project	designs	and	supply	chain	emissions.	These	factored	in	the	need	for	many	different	functions	to	
get	involved,	from	tailoring	our	communication	about	the	embodied	carbon	of	our	materials	to	different	stakeholders,	through	to	specific	materials	for	
future research and development and the engagement of key suppliers. The short-term initiatives were written in to personal and Group-wide leading 
targets	to	achieve	in	2024.

Resilience of strategy
The ‘Results’ and ‘Response’ parts of the above scenario analysis section provide assessments of the likely impact on our business, and our responses 
to improve resilience. Overall, we consider the business’ strategy to be resilient to the impacts of the CRROs which were subject to scenario analysis, 
taking into account the availability of activities we can take and are currently taking to respond to risks and capture opportunities, along with the 
relatively	low	financial	impacts	modelled.	Ongoing	assessment	of	climate	related	risks	and	successive	scenario	analysis	exercises	will	be	used	to	
continually evaluate the resilience of our strategy going forward. 

The	table	below	describes	the	potential	impact	of	the	CRROs	judged	to	be	most	significant	for	the	Group,	and	our	strategic	response	to	these	CRROs.	
This prioritisation has been based on our exposure to the risk or opportunity, which is given by business division, and the time horizon we anticipate 
impacts	to	take	effect	over.	It	also	provides	Keller’s	strategic	response	to	either	mitigate	risk	or	capture	opportunity.	

The strategic responses detailed in the table below intend to build operational and regulatory resilience to climate change, to support the continued 
resilience of our strategy.

The risk categories (Low/Medium/High) given in this statement for CRROs refer to residual risk rather than raw risk, and factor in mitigations, as 
described	in	the	table	below.	As	this	is	a	different	presentation	of	risk	to	last	year’s	TCFD	statement,	the	risk	categories	for	each	CRRO	have	changed	
and are lower in most instances as they now factor in mitigations.

Potential for loss of market share if clients require transparency in, and associated reductions of, Scope 3 emissions, although most clients have 
not yet enquired about Scope 3 emissions. In addition, potential for loss of suppliers if requirements become too burdensome for SME operators.

Strategic response

•  We are working to embed automatic Scope 3 calculations in our ERP programme development.
•  We are conducting a business unit trial in Austria to calculate business unit-wide material Scope 3 emissions.
•  Collaborate with industry trade associations to request emissions data from suppliers and set minimum carbon reporting standards.

Our process for managing climate-related risks 

The	significance,	size	and	scope	of	identified	climate-related	risks	is	determined	through	the	same	processes	that	are	applied	to	other	risks	identified	
by	the	Group.	Risks	are	initially	identified	and	assessed	at	business	unit	or	functional	level,	and	reported	to	the	Group	Head	of	Risk	and	Internal	Audit	
and the Executive Committee, and in turn to the Board and the Audit and Risk Committee. Business unit leads are then assigned CRROs relevant 
to	their	own	geography	and	services	which	they	are	made	responsible	for.	CRROs	are	evaluated	for	their	velocity,	probability,	potential	financial	and	
reputational impact, and assigned an overall quantitative score of severity of risk, that is then consolidated at Group level to produce a qualitative view 
of the relative severity of CRRO risk by geography. The CRROs are assessed in consideration of their associated mitigating activities, and the impacts 
are	then	determined	on	a	residual	risk	basis.	This	is	reflected	in	the	CRRO	table	above.	The	outputs	of	the	scenario	analysis	are	also	used	to	inform	our	
risk assessment of how CRROs impact our business. As we increase the number of CRROs subject to scenario analysis, this exercise will more closely 
inform our overall assessment of the impacts of climate risk.

Regular risk reviews are conducted within our business units and functions facilitated by our Group Head of Risk and Internal Audit. The methodology 
used to identify the materiality of CRROs can be found in the Strategy section of this statement, including a full list of CRROs. Climate change-related 
risks are assessed as part of the risk governance framework in the same way as other risks, including decisions on how to mitigate, accept, and manage 
risks. The full risk governance framework, including an overview of our risk management processes, can be found on page	36 in the Principal Risks and 
Uncertainties section.

Potential impacts from existing and emerging regulatory requirements relating to climate change in our divisions were addressed through our scenario 
analysis work, which can be found in the Strategy section of this statement.

Metrics and Targets

Our metrics for assessing CRROs

This year, we have expanded the metrics we use to assess our CRROs. 
Our newly implemented ERP assists us with collecting and reporting 
these metrics at a Group level. We are aiming to continue to expand the 
metrics we collect and report on, so that all of our CRROs are tied to 
cross-industry metrics. 

CDP score: B (2022: B)

CDP is a third-party disclosure system which assesses the quality of 
our TCFD disclosure. This provides overarching metrics to help us 
consider our progress against the risk of not being able to meet the 
reporting standards of clients. This score can be compared with the 
construction sector, and with all other companies reporting through CDP. 

Percentage of revenue from water storage 

and flood control projects, and from non-fossil 

fuel based power generation: 3% (2022: 2%)

This metric can be used to track the project opportunities arising from 
climate change and the transition to a low-carbon economy. In terms of 
opportunities arising from the physical impacts of climate change, this 
includes	flood	defence	projects	and	projects	that	help	to	secure	water	
supplies. In terms of opportunities arising from a transitioning energy 
system, this includes renewable energy generation projects. 

Investment into sustainability-focused 

research and development: £0.3m (2022: £0.2m)

This	total	includes	our	spend	on	HVO	fuel	trials,	KGS	KB0-E	spend,	and	
other university projects in Europe, North America and AMEA.

The Remuneration Committee agreed a Scope 2 reduction target as one 
of management’s corporate objectives linked to remuneration for 2023. 
More detail on this objective and remuneration outcome is available in 
the Directors’ remuneration report on page	136.

For quantitative disclosures concerning our energy usage, please see our 
Streamlined Energy and Carbon Reporting (SECR) statement on page	65.

These metrics address some of our most material CRROs. We are 
working to develop other metrics to address our remaining CRROs. We 
are also working to develop quantitative metrics to address water and 
waste management. Qualitative disclosures on water and waste, as well 
as on other environmental topics, can be found on page	68 of this report. 

We do not currently use an internal carbon price.

GHG emissions reporting

The Group discloses Scope 1 and Scope 2 carbon emissions to ISO 
14064-3	Standard,	and	are	calculated	using	the	GHG	protocol	standard.	
Independent	verification	is	provided	by	Accenture.	Our	Scope	1	and	2	
emissions are provided on page	65 as part of our Streamlined Energy 
and Carbon Reporting (SECR). These emissions are recorded both in 
absolute terms, as well as relative to revenue to show the carbon intensity 
of our operations.

For	Scope	3	emissions,	to	reflect	where	we	believe	we	can	have	the	
most near-term impact, we currently only have a net zero target set 
for our Operational Scope 3 emissions. This covers business travel, 
transportation of materials, and waste disposal. Scope 3 calculation and 
reporting will be included as part of the new ERP program. 

Calculating emissions for other Scope 3 categories, including for our 
materials, poses challenges due to the complexity of our supply network 
and our high number of small suppliers. Progress towards calculating 
further Scope 3 categories was made in our European BU this year, 
where initial work on calculating our Scope 3 emissions for materials was 
expanded on a trial basis to the full BU, providing a guiding approaching 
for this category and others as we build on the completeness of our 
calculations. As part of the development of our ERP, we are working with 
procurement teams to ensure Scope 3 data can be calculated at the 
invoicing stage, rather than relying on manual data entry at site level. 
Further details on our decarbonisation work and Scope 3 can be found 
on page	67. 

Details on our approach, including how we train engineers in calculating 
and reducing carbon in our projects, can be found on page	67.

The Group has targets for all three scopes, which are calculated 
according to the GHG protocol and are in compliance with SECR 
requirements. 

These absolute targets assist the Group in mitigating future climate 
related risks and in recognising climate-related opportunities. All targets 
use a 2019 baseline where available. 

Scope 1 – Net zero by 2040 
Scope 1 carbon intensity target of a 35% reduction in tCO2e/£m revenue 
for	2024	(against	2019	baseline).	This	2024	target	would	result	in	a	5%	
reduction in our carbon intensity from 2023. 

Scope 2 – Net zero by 2030 
Interim target of 50% reduction in absolute market-based emissions 
for	2024	(against	2019	baseline).	This	2024	target	would	result	in	a	10%	
reduction from 2023. 

Operational Scope 3 – Net zero by 2050
Operational Scope 3 includes business travel, material transport and 
waste disposal. 

In order to achieve these targets, we have set multiple internal leading 
targets built around our carbon hierarchy, which is detailed on page 
64. Once we have worked through this hierarchy to eliminate, reduce 
and	substitute	emissions,	we	may	offset	our	remaining	emissions	as	a	
last resort.	

We also specify multiple leading targets under each absolute target, to 
help achieve each net zero target. These range from conducting energy 
efficiency	audits	in	our	offices	and	yards,	through	to	conducting	specific	
carbon reduction site trials and training our engineers on the sector 
standard carbon calculator. 

For more information on the Group’s emissions and associated targets, 
please see pages	63	to	67.

Metrics and Targets a) Disclose the metrics 
used by the organization to assess 
climate-related risks and opportunities in 
line with its strategy and risk management

While we have published cross-industry 
metrics as described in Table A2.1 of the 
TCFD implementation guidance, we do not 
have a complete list for all material CRROs. 

Furthermore, we have qualitative 
information available on water and waste, 
but not quantitative metrics.

We also recognise that the TCFD 
recommendations encourage the 
disclosure of Scope 3 emissions and we 
have published our operational Scope 3 
emissions and target.

We expect to add additional metrics for our 
CRROs next year.

For metrics and targets concerning water 
and waste management, establishing these 
will be subject to a materiality assessment 
to determine if these topics are material to 
us,	which	we	will	undertake	in	2024.	If	
determined to be material, we would work 
on developing appropriate metrics and 
targets for these topics.

We are actively working on improving the 
scope and quality of the Scope 3 categories 
we calculate and disclose, with the aim of 
publishing our full Scope 3 emissions in 
future. Scope 3 calculation and reporting 
will be included as part of our upcoming ERP 
programme.

Peter Hill CBE

Chairman

We have met our short-term 
carbon targets and are well on 
track to achieve our longer-term 
net zero commitments.”

Our corporate purpose, ‘Building the foundations for 
a sustainable future’, is at the heart of everything 
we do. I am the Director responsible for ESG and 
sustainability on the Board and I believe strongly in 
Keller’s commitment to the best achievable standards. 
I have a strong desire to make a positive change.

As the world’s largest geotechnical specialist contractor, we have the 
responsibility	and	opportunity	to	make	a	difference	to	our	customers	
and society and to help drive a low carbon future. We are committed to 
reducing the carbon intensity of our work and have set out clear targets 
and	action	plans	for	our	journey	to	net	zero.	We	set	our	first-ever	net	
zero targets during 2021, to be net zero by 2050, and I am able to report 
good progress against this key priority. We have met our short-term 
carbon targets and are well on track to achieve our longer-term net 
zero commitments.	

Our people’s safety, health and wellbeing is at the heart of everything 
we do. At Keller we view safety as our bedrock, something on which 
we do not compromise. We have made good progress in improving the 
scores in our leading indicators, targeting continuous improvement in 
our	Accident	Frequency	Rate	(AFR)	and	Total	Recordable	Incident	Rate	
(TRIR).	In	2023,	AFR	remained	at	0.10,	with	a	total	of	27	injuries	reported	
and TRIR improved to 0.60, with 26 fewer injuries recorded. Despite 
achieving	industry-leading	figures	in	this	area,	we	recognise	the	need	to	
continually	improve	and	we	will	not	be	satisfied	until	we	eradicate	harm	in	
the workplace. 

Keller’s Inclusion Commitments bring together what we are doing across 
Keller to build a more diverse, equitable and inclusive workplace. During 
2023, we introduced a new Inclusive Site Culture standard to enhance 
our culture at site, ensuring employees are not only physically safe, but 
feel psychologically safe, included and respected through measures 
such as inclusive personal protective equipment, and making reasonable 
accommodations	for	different	cultural	and	religious	identities.	

Due to the breadth of our operations, including geographies and industry 
sectors, we recognise that we need to be vigilant to the risk of slavery 
in our supply chains. During 2023, the Board engaged outside legal 
counsel to review its approach to managing the risks associated with 
human rights in its operations and is taking proactive steps to drive 
awareness and compliance with our standards through the business and 
in	our	supply	chain.	For	further	information,	please	refer	to	our	Modern	
Slavery	and	Human	Trafficking	Statement	for	the	financial	year	ended	
31 December	2023,	which	is	available	on	our	website.

The Board continued to receive quarterly reports on all ESG initiatives 
and deliverables from the Group Company Secretary and Legal Advisor, 
assuring a clear reporting line on all ESG matters to me and to my fellow 
Board members. 

I would like to thank everyone at Keller for their continued commitment 
to our ESG and sustainability agenda.

Carbon reduction

Keller has net zero targets which 
cover our direct emissions (Scope 
1),	our	indirect	emissions	from	
electricity	use	(Scope	2)	and	
emissions from business travel, 
waste disposal and material 
transport	(Scope	3	Operational).	
These targets represent Keller’s 
commitment to the planet as 
we build the foundations for a 
sustainable future.

These absolute targets will help us mitigate 
future climate-related risks and recognise 
climate-related opportunities. We divide our 
emissions targets using the scopes set out in the 
GHG Protocol. These targets and our current 
performance are set out in the following section. 
The timeframe and lagging targets we set for 
each	net	zero	commitment	reflect	the	size	and	
the level of control we have over each emission 
scope (see below). To achieve these targets, we 
have set multiple internal leading targets, built 
around the carbon hierarchy (see right). 

This explains that, after we work through the 
hierarchy to eliminate, reduce and substitute 
emissions,	we	may	offset	our	remaining	
emissions as a last resort.

Protecting  
NYC from 
future floods

In the US, New York City was one of the places 
worst hit. The devastation prompted the city 
to urgently review its ability to cope with storm 
surges and rising sea levels exacerbated by 
climate change, leading to the launch of the 
$1.2bn	East	Side	Coastal	Resiliency	(ESCR)	
project. 

Keller has played an integral role in 
a major project to raise part of New 
York’s coastline and reduce the risk 
of disastrous floods. 

ESCR	is	the	first	step	in	the	city’s	plan	to	
protect	Lower	Manhattan	and	will	create	a	2.4-
mile	flood-protection	system	with	new	walls	
and gates, improved drainage and an elevated, 
reconstructed East River Park. 

Hurricane Sandy was the largest Atlantic 
hurricane on record, killing over 230 people in 
eight countries and causing $70bn in damage. 

It’s this ambitious 10ft elevation where Keller 
has played a key role, constructing around 
2,500 aggregate piers to improve the soft 
coastal soils and enable redevelopment – the 
success of which led to us being awarded a 
second phase of 500 micropiles. 

Ready to play our part
“This	has	been	a	hugely	significant	project	in	
terms of its size, complexity and the impact 
it will have on millions of people,” says David 
Finocchio, Business Development Executive. 
“Coastal resiliency is a massive, growing 
market of strategic importance to Keller, 
particularly here in the US Northeast. 

“As leaders in our industry, we understand the 
responsibility we have to use our expertise and 
resources to support these kinds of projects. 

“There’s no doubt that many more large 
infrastructure programmes will be required in 
the US as the threat from climate change and 
extreme weather increases. And when they 
are, Keller will be ready to play its part.”

We’re driving a greener 
construction industry by 
helping our clients reduce the 
environmental impact of their 
projects through optimised 
designs, more sustainable materials 
and alternative power sources.

One	such	project	is	Hafenpark	Quartier	Offices,	
part of a landmark mixed-use development 
close to the European Central Bank, featuring 
luxury	apartments,	an	office	tower,	hotels	
and conference facilities. The client, B&L Real 
Estate,	wanted	the	project	to	have	the	first	
carbon-neutral excavation pit and foundations 
in Germany and so chose Keller in part because 
of our sustainability commitments.

“We started by taking the client’s initial design 
for a secant retaining wall with cased CFA piling 
and ground anchors, along with micropiling and 
large-diameter foundation piles – then using 
our carbon calculator to demonstrate its carbon 
footprint,” says Eva Reiners, Site Engineer.

The calculator is an app we use not only to work 
out the embodied CO2e from materials, but 
also from machinery fuel use, transportation 
of equipment and people, waste disposal, site 
electricity and more. It follows the sector-
standard approach of the European Federation 
of Foundation Contractors and Deep 
Foundations Institute.

The Keller team was able to make other 
environmental improvements by changing 
suppliers to reduce transport distances for 
materials and waste, using an electric concrete 
mixer and, at times, operating plant fuelled 
with hydrotreated vegetable oil. A solar panel 
was also set up to power the construction site 
facilities.

“Taking	the	initial	figures,	our	experts	then	
optimised and value engineered the design,” 
she adds. “This meant we could reduce the 
anchor layers required from three to two, by 
using	single	bore	multiple	anchors	(SBMA)	
in the second layer, as well as switching to a 
lower-carbon cement mix.”

Thanks	to	our	efforts,	we	were	able	to	reduce	
emissions by 50% from B&L Real Estate’s 
baseline. They can now build on those savings 
to achieve full carbon neutrality through 
investment	in	certified	reforestation	and	other	
compensation methods.”

Overall performance
This year, Keller’s overall Scope 1 and 2 emissions decreased. This mostly 
reflects	a	change	in	projects,	with	fewer	carbon-intensive	projects,	like	
bucket mixing environmental remediation. In terms of the carbon intensity 
of our operations, emissions relative to revenue continued to fall and even 
outpace	inflation.	This	reflects	the	range	of	carbon	reduction	and	efficiency	
improvements implemented throughout the year (see pages	66	and	67), 
as well as improvements in revenue. It also means that Keller’s total relative 
emissions have either remained level or fallen every year since 2017.

Based on the data and information provided by Keller and the processes 
and procedures conducted, Accenture concludes with limited assurance 
that the GHG assertion:

• 
• 
• 

is materially correct;
is a fair representation of the GHG emissions data and information; and
is prepared in accordance with the criteria listed above. 

It is our opinion that Keller has established appropriate systems for the 
collection, aggregation and analysis of quantitative data for determination 
of these GHG emissions for the stated period and boundaries.

Third-party assurance statement
At the request of the Director responsible for sustainability, Keller seeks 
annual	third-party	verification	of	our	emissions.	This	verification	process	is	
compliant	with	the	same	consolidation	rules	as	are	applied	to	our	financial	
accounting.	This	is	consistent	with	the	approach	used	in	the	ISO	14040	
series	and	reflects	the	impact	we	have	on	overall	emissions	in	our	entities.	

Independent	verification,	in	accordance	with	best	practices	required	by	
ISO	14064-3	Standard,	on	the	Scope	1	and	Scope	2	GHG	accounts	has	
been provided by Accenture. Their summary opinion is provided below (full 
opinion and recommendations are available on request). 

CDP
As in previous years, Keller disclosed our climate change performance to 
CDP. CDP assesses the carbon intensity of Keller’s operations, as well as 
our ability to identify and mitigate climate-related risks and opportunities. 
In 2023, we achieved a score of B. This is the same as in 2022, with Keller 
remaining above the global average CDP score of a C. Since this CDP score 
reflects	our	progress	in	2022,	the	score	does	not	include	our	progress	
on quantitative climate scenario analysis and wider TCFD improvements. 
These	should	be	reflected	in	next	year’s	CDP	score.	For	more	on	our	climate	
risks and opportunities and TCFD, see pages	48	to	58.

Scope 1: Direct emissions

Net zero by 2040

Scope 1 covers our direct emissions. These 
mostly arise from the fuel use of our rigs and 
Keller vehicles. Keller’s 2023 Scope 1 emissions 
have decreased since 2022. Scope 1 fuel 
emissions are highly dependent on the projects 
completed annually. With fewer projects in the 
US,	as	well	as	a	drop	off	in	our	more	carbon-
intensive bucket mixing projects, Keller’s overall 
emissions have decreased. 

More importantly, the carbon intensity of our 
operations has decreased. This means we 
have continually decreased or maintained our 
Scope 1 emissions per £m revenue year on year 
since 2017. This reduction in relative emissions 
reflects	a	number	of	carbon	reduction	initiatives	
that were introduced this year. All these initiatives 
are needed to decouple our growing work from 
absolute Scope 1 emissions. Our initiatives are 
focused around the three stepping stones set 
out in our equipment decarbonisation strategy: 
efficiency	improvements,	alternative	fuels	and	
alternative equipment.

In	terms	of	efficiency,	2023	saw	us	collate 	
and share	case	studies	on	fuel	savings	from 	
across the Group. For example, ASEAN 
conducted an initiative to compare actual 
fuel use	of	generators	with	the	expected	
factory	specification.	This	led	to	them 	
changing out the most fuel-intensive 
generators	for	those that	were	more	
efficient, saving	fuel, carbon	and	money.	 
Other case studies focused on topics such 
as right-sizing equipment for our projects, or 
switching to smaller generators/grid electricity.

In terms of alternative fuels, in 2023 we set out a 
specific	budget	to	trial	biofuels	in	more	entities	
across Europe and North America. This means 
we	can	now	offer	certified	biofuels	to	clients	who	
are willing to pay a premium for a lower carbon 
project. These also represent a stepping stone 
to decarbonise our existing equipment, before 
we are able to switch to alternative equipment.

In terms of alternative equipment, at the half 
year	we	announced	the	production	of	our	first	
electric rig, the KB0-E. This has successfully 
been deployed in Austria. As well as decreased 
emissions,	the	KB0-E	has	additional	benefits	to	
being	run	off	of	mains	power,	including	reduced	
noise, fewer moving parts for maintenance and, 
with no tailpipe emissions, an ability to use it in 
confined	spaces.	We	also	hired	two	other	plug-
in electric rigs for projects in Sweden, Norway 
and Austria, for the same price as their diesel 
equivalents. All the rigs we produced in 2023 
were	electrohydraulic	or	fitted	with	the	latest	
tier 5 engines.

Although most of our emissions come from 
our	rigs,	our	vehicle	fleet	is	also	a	large	source	of	
emissions. Therefore, in North America, where 
vehicle emissions are largest, we introduced a 
company car reward scheme for those choosing 
electric and hybrid vehicles. In many of our 
European business units, we continued to set 
minimum car scheme requirements to improve 
air quality and reduce emissions.

Delivering  
on our carbon 
targets in India

Keller India has created its first net 
zero Scope 2 yard after efficiency 
improvements and solar panel 
installation in Delhi.

In	the	first	quarter	after	installation,	the	Delhi	
system produced net-negative Scope 2 
emissions. The success follows lessons learned 
from the earlier installation of solar panels at 
the Chennai yard.

When solar power generates more energy 
than the yards need, the systems send the 
excess to the grid. 

Thanks	to	efficiency	improvements	reducing	
their	electricity	demand,	feed-in	tariffs	mean	
Keller India saves thousands of pounds a year 
on its energy bills, with a return on investment 
forecast within a few years.

The maintenance yards contribute 30% of 
the business unit’s Scope 2 emissions, which 
includes all indirect emissions from purchased 
energy. Combined, the solar panels in Keller 
India’s Delhi and Chennai yards generate 
74,000kW a year, saving around 51 tonnes of 
CO2 equivalent (tCO2e)	–	the	same	as	a	petrol	
car driving more than 200,000km.

Globally, Keller is committed to becoming net 
zero for Scope 2 emissions by 2030. Keller 
India is playing its part, reducing Scope 2 
emissions from 246tCO2e in 2019 to 160tCO2e 
in 2022. Together with other energy-saving 
improvements, the solar panels will help bring 
that	figure	down	to	zero	by	the	end	of	the	
decade.

Keller India has worked hard to 
cut their emissions and create our 
first net negative yard for Scope 
2. Rather than simply switching 
to a green energy tariff, they have 
had to improve the efficiency of 
their operations and invest in solar 
panels for the future.”

Scope 2: Indirect emissions from electricity

Net zero by 2030

Scope 2 covers indirect emissions from the 
electricity we use. These emissions are mostly 
from	office	and	maintenance	yard	operations,	
although	2023	also	saw	our	first	large	sites	
run entirely from grid electricity. Nonetheless, 
Scope 2 is still the smallest of Keller’s three 
emission Scopes. Since these emissions do not 
significantly	vary	with	the	number	of	projects	
carried out, we only analyse absolute Scope 
2 emissions. Location-based emissions are 
dependent on the average carbon intensity 
of energy generation in the countries in which 
we operate. Market-based emissions use the 
specific	energy	tariff	for	each	of	our	offices	and	
maintenance yards and therefore captures green 
energy	tariffs.	

This year, Keller linked leadership remuneration 
to a 38% reduction in market-based Scope 2 
emissions, based on our 2019 baseline year. 
This	target	reflected	a	further	10%	reduction	on	
2022. This was successfully achieved, with Keller 
seeing	a	48%	reduction	on	our	baseline.	

This continued decrease demonstrates the 
success of our Scope 2 decarbonisation 
strategy.	It	also	reflects	the	work	of	“Team	
Planet” volunteers across Keller, taking steps to 
improve	their	own	offices,	maintenance	yards.	
and sites. 

Scope 3: All other indirect emissions

Most of these savings came from the work of 
Suncoast, our specialist post-tension steel 
specialist, which now represents approximately 
a quarter of all the Group’s Scope 2 emissions. 
Through	efficiency	improvements	and	switching	
to	green	energy	tariffs,	they	reduced	their	
emissions by nearly 1,000tCO2e in 2023. The 
growing	difference	between	location-based	and	
market-based	Scope	2	emissions	reflects	how	
some of our business units, particularly in North 
America	and	Europe,	are	now	procuring	certified	
renewable	power	electricity	for	the	first	time.

Where	green	tariffs	are	unavailable,	such	
as in much of AMEA, business units 
focused	on	efficiency	improvements	and	
generating their own	electricity.	For	example,	
in 2023, Keller India installed over 35kWh’s 
worth of solar panels in their new Delhi yard; 
when coupled with air conditioning and 
lighting upgrades, this yard was net negative 
for electricity use throughout the end of the 
year, contributing more electricity to the local 
grid than they consumed themselves. Austria, 
Austral, Poland and the UK also all generated 
their own renewable energy using solar panels. 
Note	all	these	efficiency	initiatives	come	with	
short or medium term payback periods.

Net zero for Operational Scope 3 by 2050

Scope 3 represents all other indirect emissions 
from Keller’s supply network. This means Scope 
3 is the largest proportion of Keller’s emissions. 

To	reflect	where	we	believe	we	can	have	the	
most impact, we have set a net zero target for 
Operational Scope 3. This covers business travel, 
transportation of materials, and waste disposal. 
UK Scope 3 business travel has continued to 
increase since 2022, particularly as processes 
have	been	centralised	and	Group	Head	Office	
grows to incorporate the ERP team. 

We do not currently calculate or disclose our 
wider Scope 3 emissions. However, we continue 
to develop our Scope 3 reporting to include the 
rest of our Operational target, building these 
transportation emissions into the upcoming 
ERP system.	

In the meantime though, we continue 
to develop our Operational Scope 3 
decarbonisation	strategy.	For	our	offices,	this	
means encouraging the use of video calls to 
reduce	the	need	to	travel	between	offices.	 

For personal vehicles, we have introduced 
air quality requirements, with North America 
introducing	financial	incentives	for	employees	
that choose electric or hybrid vehicles on the 
company car scheme, On our sites, we also 
have initiatives such as 5S and containerisation 
to reduce the number of trucks needed to 
mobilise and demobilise our equipment.

For Materials Scope 3, we used workshops 
throughout 2023 to set out our short, medium 
and long-term material decarbonisation 
initiatives. Keller looks to reduce Materials Scope 
3 emissions by designing ground improvement 
solutions rather than heavy foundations 
and optimising designs for less and lower-
carbon materials.	

However, we are still dependent on our supply 
network decarbonising their activities. Since 
we work with local material suppliers on each 
project, we have thousands of suppliers in our 
value chain. Using many small suppliers for 
individual projects means we lack leverage when 
it comes to decarbonising our supply network. 

Our approach to Materials Scope 3 is therefore 
focused on creating the drivers to encourage 
smaller suppliers to decarbonise, as well as 
engaging with larger stakeholders to help drive 
decarbonisation. For example, we are working 
with our trade associations across Europe 
and North America to collectively leverage our 
supply network to drive decarbonisation. We 
are also looking to form strategic partnerships 
with larger suppliers to help decarbonise our 
material emissions.

In terms of measuring all Scope 3 emissions, 
we are integrating these into the upcoming ERP 
project. This will also enable us to estimate a 
range of other sustainability impacts from our 
supply network. For now, as of 2023, we have 
trained over 900 employees on the sector-
standard EFFC–DFI embodied carbon calculator. 
This has enabled us to start proactively 
monitoring our Scope 3 emissions on key 
projects.	More	importantly,	it	also	offers	the	
opportunity	to	offer	lower-carbon	solutions	to	
our clients, as well as helping identify carbon-
intensive Scope 3 hotspots to target with future 
carbon reduction initiatives.

Local priorities

Resource use and 
waste reduction 

This	initiative	reflects	the	
contribution Keller can make 
towards the circular economy. In 
particular, we look to reduce raw 
material use, increase our use of 
secondary materials, reduce waste 
to	landfill	and	allow	for	pile	reuse. 

Tackling pollution 

Keller is committed to delivering 
its solutions in a socially and 
environmentally conscious 
manner. Over recent years 
reporting processes have improved 
and performance is generally 
encouraging.  

The overall number of environmental incidents 
remained in line with those reported the previous 
year, with most incidents being minor hydraulic 
leaks. We have therefore been rolling out our 
improved equipment inspection process, 
using our site software prior to each shift 
commencing,	in	an	effort	to	reduce	the	number	
of minor spills.

We continue to work on our preventative 
maintenance programmes to ensure that we 
address any issues before the event occurs. In 
addition, we ensure that secondary containment 
is in place for stored equipment and materials. 
We continually seek to improve our processes on 
site,	specifically	around	job	planning,	to	ensure	
that we identify, mitigate and control our risks 
and minimise our environmental impact. More 
details can be found in our biodiversity policy.

We recognise the large volumes of materials 
used and produced on our sites, so we have a 
number of projects to improve these impacts. 
In 2023, we contributed to cross-sector 
research and development of a circular 
economy guide for geotechnical companies. 
Critically, this shares good practices that all 
geotechnical companies can adopt to improve 
their impact on the circular economy. This will 
help the whole sector understand their current 
circular economy impacts and meet upcoming 
legislation in this space.

Internally, Keller routinely promotes ground 
improvement solutions as a way to reduce raw 
material use on site. Ground improvement uses 
natural or recycled materials to improve ground 
load carrying capacity. This reduces or completely 
removes the need for heavy foundations. In turn, 
this reduces the volume of cement and steel 
used on site, saving primary resource use, and 
potentially	offering	a	financial	saving	to	our	clients.	
The reduced need for heavy foundations also 
reduces the carbon intensity of the overall project. 

More details on what we ask of our supply chain 
in terms of waste reduction can be found in our 
Supply Chain Code of Business Conduct.

As well as addressing our use of raw materials, 
we are also keen to reduce waste. Of all the 
geotechnical	solutions	we	offer,	our	jet	grouting	
solutions have traditionally used the most water 
and created the most waste spoil. Therefore, 
our research and development teams have 
been trialling ways to monitor and reduce these 
impacts.	Using	a	combination	of	filter	chamber	
presses, centrifuges and shale shakers, we are 
now able to reduce the volumes of waste water 
and spoil produced on jet grouting sites. As 
well as reducing the cost of waste disposal, this 
has	the	added	benefit	of	reducing	the	number	
of	trucks	required	to	transport	materials	off	
site. This reduces congestion around our sites, 
improving air quality and reducing our impact 
on the local community. We also have a number 
of ongoing research projects looking to use 
alternative materials for jet grouting and allow 
the	reuse	of	grout-filled	spoil.

Whilst as subcontractors we have limited control 
on biodiversity on site, multiple business units 
continue to engage with local organisations 
and wildlife trusts to promote local biodiversity. 
Nonetheless,	for	our	own	operations	on	specific	
projects, we make use of dust suppression 
and	baffling	to	minimise	the	impact	of	dust	
and noise on the local environment. We also 
typically use local material suppliers to support 
local businesses, reduce transport distances 
and reduce congestion around our sites. We are 
engaging with our trade associations to highlight 
upcoming legislation and best practices for the 
geotechnical sector.

Water use

This year, we introduced a new local 
initiative focused on water use. This 
reflects	both	our	work	on	water-
related projects, as well as our own 
initiatives to reduce water use and 
avoid water pollution.  

In terms of our solutions, we work on a number 
of water-related projects around the world. From 
installing	the	foundations	of	flood	defences	to	
grouting around dams, Keller is involved in many 
projects	to	help	mitigate	the	effects	of	drought	
and sea level rise. This work will only increase 
with the physical risks and opportunities arising 
from	climate	change.	We	also	offer	solutions	
to help remediate contaminated ground water. 
This includes	solutions	such	as	slurry	cut	off	
walls, as well as innovations like our Halocrete® 
grouting solution.

When it comes to our own operations, we focus 
on water reduction on key projects and countries 
where water is less available. We have a Keller 
employee in Keller Bahrain carrying out a PhD 
focused on water reduction in our design and 
site operations. Similarly, we are also contributing 
to cross-sector trade association work on water 
reduction, highlighting upcoming legislation and 
best practices in our sector.

Listen

As part of our commitment to continue 
to understand what is important to our 
underrepresented workforce, we actively 
support the creation of employee-led 
networks. Keller Women in Construction 
(KWIC) brings together women and allies 
from across the organisation to promote 
inclusiveness, foster a supportive working 
environment and boost career development. 

•  KWIC AMEA established a divisional 

mentorship programme with relevant guides 
and resources to navigate the mentoring 
relationships. In addition, the committee 
facilitated an allyship webcast across the 
division which included participation from 
the senior	leadership	team.

•  KWIC North America have focused on four 
key initiatives during the year, including: 
promoting professional development (both 
internally and industry-wide), creating 
an internal women’s network to enhance 
corporate	culture,	supporting	efforts	to	
increase the recruitment and retention 
of women, and engaging with local 
communities	through	outreach	efforts.	
Focus groups with women on site were 
conducted and action plans established to 
address issues raised.

•  KWIC Europe launched and promoted a 
new intranet site to connect colleagues 
and provide them with opportunities 
to collaborate across the division. The 
committee	also	continued	to	raise	the	profile	
of KWIC at various divisional events and 
spotlight inspirational female colleagues. 
To inspire and empower colleagues, the 
committee hosted two webcasts: ‘Imposter 
Syndrome’, and ‘Personal Development 
Unlocking Potential’.

related guidance was developed to address 
specific	gender	inequities	on	site	such	as	
inclusive personal protective equipment, 
access to lockable toilet facilities for both 
men and women, and lactation facilities 
for mothers who return to work if needed. 
The standard also highlights minimum 
requirements for welfare and hygiene 
facilities and how sites can make reasonable 
accommodations	for	different	cultural	and	
religious identities.

•  Specialist development programmes were 
initiated to support women in North-East 
Europe and South-East Europe and Nordics.

•  To promote health equity, colleagues in 

UA and Oman attended Women’s Health 
Awareness events and we introduced health 
screening services for colleagues in UAE.

•  Colleagues continued to support local 

communities across the globe. For example, 
Keller Malaysia refurbished facilities and 
raised vital funds for Ahsana Welfare Centre, 
a charity in Kuala Lumpur that provides 
education, care and protection for women 
with special needs, and delivered talks on 
general health and safety as well as sexual 
harassment and bullying. North America 
engaged with several charities throughout 
the	year	including	US	Marines’	Toys	4	Tots	
to support families during the festive period 
and the Susan G Komen Foundation in 
support of breast cancer awareness.

•  As part of Inspiring Women in Construction 

and Engineering, our Group Head of 
Talent and Diversity joined a mentoring 
programme with Construction News and 
New Civil Engineer to support women 
entering	the	field	of	engineering.

Evolve 

•  Established a global PPE project team 

with divisional representation to ensure 
all colleagues have access to inclusive 
PPE. Externally we have engaged with 
manufacturers and providers, and together 
with an external peer network, continue to 
influence	change	in	the	industry.	

•  Established a Global Talent Task Force to 

identify and address challenges on attracting 
and retaining talent with an initial focus on our 
emerging workforce (including engineering 
graduates and apprentices).

•  Keller Australia reviewed and updated their 
parental leave policy to ensure inclusivity of 
all parents.

Inclusive Site Culture standard

“We	want	everyone	at	Keller	to	feel	empowered	
to deliver their best work,” adds Sandy-lee.  
“So,	we	are	working	hard	to	make	sure	everyone	
feels safe, valued and respected regardless of 
gender, abilities, culture, religion or stage of life. 
We know those who feel included and listened to 
perform better, creating a more productive and 
safer	workplace for	all.”

A pan-global PPE project team has been set up 
to understand which regions present the biggest 
challenge. They are working with procurement, 
manufacturers and suppliers to test safety gear, 
give feedback and partner to continue driving 
change in our industry.

The standard also highlights minimum 
requirements for welfare and hygiene 
facilities and how sites can make reasonable 
accommodations	for	different	cultural	and	
religious identities. And, to ensure collective 
progress, we have embedded the standard 
requirements into our HSEQ assurance plan, site 
verification	audits	and	leadership	interactions.

Keller launched a new Inclusive 
Site Culture standard in 2023 as 
part of our ongoing commitment 
to ensuring everyone feels safe, 
included and respected when they 
work on our project sites.

“Following	feedback	we	received	from	women	
on	site	focus	groups,	we	identified	a	number	of	
areas of improvement,” says Sandy-lee Connolly, 
Group Head of Talent and Diversity.

“Specific	gender	inequities	we	are	addressing	
relate to personal protective equipment (PPE), 
access to lockable toilets for both men and 
women, and a private, clean space for lactation 
purposes for mothers when they return to work.”

One way Keller is making improvements is 
by better supporting the growing number of 
women working on our sites and ensuring PPE 
is suitable. PPE is still largely designed with men 
in mind, meaning it might not perform correctly, 
and sourcing appropriate PPE is challenging in 
our industry.  

Our inclusion and
diversity data –
measuring and
evaluating our success

To hold us accountable in our progress to 
achieving greater inclusivity and diversity in 
the workplace, we believe transparency and 
accountability are paramount. 

At Keller, inclusion is primarily measured via 
engagement surveys and focus groups and 
we continue to check in with colleagues to 
understand whether our working environment is 
one where everyone feels respected, supported 
and valued. The data points alongside relate to 
inclusion and are based on surveys undertaken in 
sixteen businesses to date.

In addition, we examine exit interviews to identify 
common themes that may need addressing. 
To boost retention rates, we will be piloting 
stay interviews to gauge colleagues’ sense of 
workplace satisfaction and motivation.

Gender diversity

Representation matters and our ambition is 
to build more balanced teams. We continue 
to measure and monitor gender diversity 
throughout our organisation to identify where 
additional focus is needed to attract and retain a 
more diverse group of talent.

Overall, female representation remains similar 
to 2022 with the exception of the Board which 
has achieved a 50/50 gender split with the 
appointment of Annette Kelleher as Non-
executive Director in 2023. In addition, the intake 
of engineering graduates and apprentices has 
improved, with North America representing the 
most	significant	year	of	growth.	The	division	
developed new strategies to widen talent pools 
which included the implementation of a diverse 
and engaging recruitment platform, together 
with the delivery of a successful employee 
referral programme. Female representation 
in the engineering population continues to 
increase	year	on	year	due	to	accelerated	efforts	
to cultivate relationships with key universities 
and schools and through relationships with 
organisations such as Revolution Workshop 
which has provided our North America Division 
with diverse talent. Keller will continue to focus 
on bringing people into geotechnics from a wide 
range of backgrounds to ensure it has a healthy 
pipeline of skills for the future.

Gender pay gap 

Keller is committed to providing open and 
detailed information about its gender pay gap. 
The results below pertain to Keller Limited,  
a UK subsidiary of Keller Group plc. 

The	main	factors	affecting	the	increase	in	the	
mean gender pay gap primarily relate to the 
significant	increase	in	recruitment	due	to	the	
High	Speed	2	mega-project.	Specific	emphasis	
has been on strengthening the top of the 
organisation with experienced project managers. 

The	industry	suffers	from	a	lack	of	female	
representation with fewer women entering at 
graduate level and even less so working on sites. 
There are a number of actions Keller Limited are 
taking to attract and retain more women in the 
industry, including: 

We recognise that there is still a lot of work to 
do to increase the pace of change. With our DEI 
strategy in place, we are targeting incremental 
change over the longer term, which includes:

• 

•  Evolving the Keller culture where inclusion 
and respect are key leadership behaviours.
Implementing a new global performance 
development process to support the 
progress and performance of our people, 
allowing for more connected conversations 
and enabling colleagues to perform at 
their best.

•  As part of our Unearthing Potential 

programme, identifying female top talent 
within the business and ensuring robust 
development plans to support their growth.

•  As part of our commitment to enhance 
site culture, ensure business units are 
making progress against our Inclusive Site 
Culture	standard	which	addresses	specific	
gender inequities.

on career progression and which will also 
provide fair opportunities for advancement 
and compensation.

•  Strengthen our employer brand through a 
newly established global talent task force.
•  Launching an ‘All-in’ allyship programme 
to foster inclusion and create a more 
welcoming, respectful and supportive 
atmosphere that values diversity.
•  Strengthen our reporting framework 
through the delivery of a global HR 
information system which would allow  
us to capture wider diversity data.

Keller Singapore 
wins top 
wellbeing award

The country’s Workplace Safety 
and Health Council has recognised 
Keller as an employer of choice for 
its exemplary approach to mental 
health and wellbeing. 

While Singapore is renowned for its demanding 
work culture, Keller has long recognised the 
importance of promoting employee welfare. 
A wellness committee was set up in 2015 and, 
along with the safety team, has been very active 
ever since, running a wide range of health, safety 
and wellbeing activities. 

Those	efforts	were	recognised	at	the	
government’s Workplace Safety and Health 
Council Awards 2023, with Keller winning the 
Culture of Acceptance, Respect and Empathy 
(CARE) Award.

“Winning	this	prestigious	national	award	
reaffirms	that	we’re	on	the	right	track	and	
helps to	energise	our	passion	and	belief,”	 
says Seah Yeow Teck, General Manager. 

“Keller	Singapore	believes	in	Keller’s	own	
wellbeing framework of Body, Mind, Community, 
Growth and Financial Security. The journey is not 
always smooth sailing but our team has been 
pushing on, strongly believing in the positivity 
that it brings.” 

Over the years the wellness committee and 
safety team have organised group exercise 
sessions, lunchtime games and a wide range of 
other	activities.	Employees	also	benefit	from	
educational sponsorship and wellness-focused 
training,	such	as	psychological	first	aid.	

To win the award, Keller had to provide 
evidence of the company’s safety, health and 
mental wellbeing programmes and how they 
increase the performance and awareness of 
the workforce.	

The Workplace Safety and Health Council 
is a statutory body that works closely with 
the industry, unions, professionals, trade 
associations and other government agencies  
to raise health and safety standards.

Our priorities for 2023: 

Building on our strong foundation of keeping our 
people physically safe, we have increased our focus 
on all aspects of people’s health and wellbeing. 

Mental health and
resilience training 
for leaders 

As part of Suicide Prevention Day, we delivered 
a training webcast to the extended leadership 
team which emphasised the importance of 
mental health and resilience. The training 
offered	practical	tips	on	how	to	create	the	
right conditions to optimise personal and team 
performance. It also focused on how to spot and 
respond to warning signs relating to suicide.

Wellbeing as an enabler
of performance 

Creating an environment that prioritises the 
wellbeing of our entire workforce is fundamental 
for successfully implementing performance 
programmes throughout the organisation. An 
essential element of this foundation involves 
focusing on our leadership team, as they 
play a pivotal role in establishing a common 
understanding and direction for all business unit 
leaders. To support this objective, the business 
unit leadership received a presentation focused 
on providing guidance tailored to enhance 
performance. This presentation was centred on 
internal quantitative data, aimed at equipping 
leaders with the insights needed to enable and 
optimise performance within their respective 
businesses.

Global Health Challenge 

Following the success of the initial launch in 2022, we re-engaged  
with the Global Health Challenge during the year.

The challenge was an opportunity to support 
colleagues, globally, in improving their physical 
and mental health and wellbeing. As part of 
the extended programme, participants could 
also choose to take part in personal mini 
challenges focused on reducing stress, acting 
sustainably and building relationships. 

We continue to listen to our people via 
engagement surveys to understand whether 
we are making an impact and adapt our 
approach to support our people in the best 
possible way. 

Testimonials from colleagues:
“ The programme has helped me get back 
to ME!”

“ It has made a difference to my lifestyle. 
When it launched I started walking daily, 
have joined the gym, have been doing 
physical activity regularly, and maintained 
a balanced diet.”

“ The support I have received from my team 
has helped me to keep going and do more 
every day. I have felt more energetic in my 
work and able to concentrate better, so it 
has clearly made a difference.”

My immediate 
manager(s) genuinely 
cares about my 
wellbeing.”

(2022: 75%)

The data points for 2023 are based on surveys 
undertaken in five businesses units in 2023.

Generally, I believe my 
workload is reasonable 
for my role.”

“Keller	has	a	duty	of	care	to	all	its	employees	and	
this is one way we can help people recognise 
the signs in themselves and their colleagues 
that they might need some support,” he adds. 
“Every	time	I	wear	my	TradeMutt	shirt	someone	
makes a comment or asks me about it. It 
opens the door to a conversation that could 
change, or even save, a life. That power can’t be 
underestimated.” 

The funky 
shirts starting  
a conversation

Keller Australia is helping 
colleagues kickstart conversations 
about mental health – and it’s 
all down to some eye-catching 
workwear… 

Visit	a	Keller	Australia	project	site	and	you	
shouldn’t	have	a	problem	finding	our	people.	
That’s because they’re now kitted out in some 
vibrantly	coloured,	flamboyantly	patterned	
workwear. 

Created by TradeMutt, the loud and funky shirts 
and hi-vis vests are about more than just adding 
a splash of fun to the work environment; they’re 
designed to provoke discussions about mental 
health and prompt those who need it to get 
support.	“We’ve	been	focusing	on	mental	health	
at a local level for some time now, but it’s not 
easy,” explains Nigel Brockman, Queensland 
State	Manager.	“People	in	our	industry	are	often	
reluctant	to	talk	about	this	kind	of	stuff.	And	
until you’ve been there and experienced it, most 
don’t fully appreciate the importance of having 
conversations without judgement. 

Breaking down barriers 
Nigel and his leadership team thought the shirts 
were an inspired way to break down those barriers, 
so decided to provide the state’s site crews, 
workshops	and	office	teams	with	the	shirts.	

Not only are the shirt designs eye-catching, they 
also come with the slogan ‘This is a conversation 
starter’ on the back, along with a QR code linking 
to TIACS, a mental health counselling service. 

Quality education
We believe everyone has something 
to contribute to the success at 
Keller. That’s why we’re passionate 
about investing in our people 
and creating an environment of 
continuous learning, empowerment 
and inclusivity that helps people 
reach their full potential. We also 
take a leadership role in our industry 
and the communities in which we 
operate to encourage personal and 
economic growth. 

Learning and development 
programmes 
Keller’s ability to deliver its business strategy 
depends on employees with relevant skills, 
knowledge and experience. Our Group-wide 
learning and development programmes 
promote a culture that empowers our people to 
drive innovation and focus on Keller’s principal 
activities of winning and executing work on 
behalf of clients. 

AMEA continued to focus on upskilling 
leadership teams to achieve higher levels of 
performance. In 2023, business unit leadership 
training sessions were held which focused on 
competencies for senior managers.  

These were supplemented with modules 
focused	on	specific	skills	including	Conflict	
Management, Conducting Performance 
Appraisals	and	Having	Difficult	Conversations.	

To build on the Conscious Leadership 
programme which was deployed in 2022, the 
division designed a new Courageous Leadership 
programme to empower leaders to navigate 
challenges, make tough decisions, and inspire 
their teams in the face of adversity. Project 
Manager Academy sessions and Project 
Management workshops were provided 
throughout the year to upskill teams and 
equip them with the knowledge, skills and 
tools	necessary	to	effectively	plan,	execute	
and oversee projects. Technical, safety and 
operational training continued be delivered 
for Operational teams. Sustainability, mental 
health and wellbeing training programmes 
and workshops were delivered to educate and 
support colleagues across the division. 

Our Europe Division delivered a range of Keller 
Academy training programmes including 
a two-week training session for senior 
leaders, and an entry-level leadership training 
programme. Keller’s Counsellor Sales Process, 
which seeks to increase Keller’s capability in 
winning higher quality work from clients, was 
executed. A Geotechnical Construction Project 
Management Training programme is under 
development	with	a	planned	pilot	mid-2024.	
Work to enhance Commercial Training is being 
developed	and	will	be	introduced	in	2024.	

Further training courses are provided through 
the European Learning Management Platform 
and the business units in local languages. 
Evaluations	show	that	all	the	offerings	have	been	
well received by participants and have helped 
improve their skills.

North America established a Learning and 
Development Steering Committee, who have 
supported	efforts	to	identify	high	priority	learning	
requirements and to communicate availability 
of targeted learning resources to meet those 
needs. In partnership with Engineering and 
Marketing, the Learning and Development 
team launched the Technique Training Library, 
designed to help technical talent learn more 
about the various geotechnical techniques 
that the organisation delivers on. In 2023, the 
division delivered two Foundations of Leadership 
programmes, launched one Project Manager 
Academy and one Field Leader Academy. In 
addition, we are continuing to enhance and 
develop our Mentoring Program, investing time 
and development with Power BI for reporting 
on	learning	and	development,	engaged	field	
leaders	to	grow	and	develop	our	training	for	field	
and	field	management,	putting	a	large	focus	
on identifying and developing our upcoming 
talent. North America has also developed an 
orientation video, which has been added to their 
onboarding programme.

Emerging talent 
We are committed to developing our future 
talent pipeline of leaders and geotechnical 
specialists and continue to invest and equip our 
people with the skills and knowledge to drive 
the organisation forward with an ever-changing 
complex market. 

Keller has continued to focus on bringing 
people into geotechnics from a wide range 
of backgrounds to ensure it has a healthy 
pipeline of skills for the future. We continue 
to cultivate relationships with key universities 
through technology platforms that allow us to 
engage with candidates earlier in the process; 
relationships with organisations such as 
Revolution Workshop have all provided us with 
diverse talent. During 2023, North America 
established	a	6%	increase	overall	for	Asian	hires	
for entry-level full-time engineers, interns and 
co-ops. The division also had a 3% increase 
in Black hires in 2023. A major factor in the 
increase is as a result of the division’s continued 
success at targeting and following through on 
DEI initiatives, having established employee 
resource groups that partner with recruiting, 
and	enhancing	our	benefits	to	attract	diverse	
employees around North America.

Keller India developed a geotechnical 
scholarship programme in partnership with 
Bhumi, whose aim is to drive social change 
through educational opportunities for young 
adults. The scholarship will empower 15 
students with their postgraduate studies in 
geotechnical engineering.

Developing	digital	workflows	and	tools	improved	
production processes and enables us to 
deliver work well and on time. With a strong 
commitment to sustainability, we continued 
to deploy electric rigs and source alternative 
products and solutions which are more aligned 
to our sustainability aspirations. 

Global product teams 
Keller’s global product teams focus on sharing 
improvements, innovative solutions and 
product-specific	knowledge	around	the	world	
through the delivery of a monthly educational 
webcast and in-person events. Regularly 
collaborating with experts across Keller enables 
us	to	discuss	and	progress	specific	technical	
topics	in	detail,	making	sure	our	skills	and	offering	
is	safe,	economical,	sustainable	and	offers	
market-leading technologies to our customers.

During 2023, we expanded our ways of working 
and collaborating with local global product teams 
and divisional product teams across all divisions. 
This enabled us to leverage global expertise 
to provide local solutions with excellence. 

Geotechnical community 
In addition to upskilling and providing learning 
opportunities to our workforce, Keller 
proactively supports the future skills agenda 
for the geotechnical industry. Our businesses 
take a leadership role by providing employees, 
customers, suppliers and potential employees 
with	technical	papers,	seminars,	field	trips	and	
site visits. 

Keller employees maintain close contact with 
tier 1 universities to share best practice and 
undertake research projects to develop new 
and innovative products, materials and design 
approaches. This enables us to be at the 
forefront of technical advancements and allows 
us to position ourselves as the employer of 
choice in our industry. 

An award-winning safety programme

Keller has won two prestigious 
industry awards for its Step 
Forward for Safety (SFfS) 
programme, which has helped our 
UK Business Unit achieve a year-
on-year reduction in incidents. 

SFfS picked up a Gold award for Best Innovative 
Health & Safety Campaign from the European 
Federation of Foundation Contractors, as well as 
being recognised by the UK’s Federation of Piling 
Specialists in their Safety Innovation category. 

Launched by Keller UK in 2018 in 
partnership with	Active	Training	Team	(ATT),	
SFfS is a behavioural-based and cooperative 
programme that goes beyond corporate 
policies and protocols to improve the 
cultural approach	to	safety.	

“It’s	about	encouraging	individuals	at	every	
level to take responsibility for safety and what 
happens on site,” says Simon Jones, HSEQ 
Director	(Europe).	“During	an	engaging	day-long	
event, away from the usual working environment, 
SFfS gives our people a basic understanding of 
human psychology, explores why we react the 
way we do in certain situations and guides them 
through example scenarios of how incidents 
occur. Importantly, it also looks at where 
opportunities are missed to intervene.”

Practical tools for improving safety
Each session, delivered by ATT, features no 
more	than	15	colleagues	–	all	in	different	roles	
and with varying levels of experience – and is 
overseen by a Keller HSE facilitator and senior 
leader. After the session, colleagues come 
away with a common language for talking about 
safety, practical tools they can deploy and the 
confidence	to	speak	up	when	they	see	things	
that might not be right.

Over	the	past	five	years	more	than	1,000	
individuals have taken part in SFfS, including 
everyone at Keller UK, a number of colleagues in 
other business units, key suppliers, joint venture 
partners and even some clients. Plans are now in 
place to roll out the programme in Germany. 

“We’re	delighted	to	win	these	awards,	which	
are	recognition	of	the	significant	impact	Step	
Forward for Safety has had,” says Simon.

Keller Group plc  Annual Report and Accounts 2023

ESG and sustainability continued
Principles

Good governance

Good governance is about balancing 
the needs of stakeholders and 
helping to run the company well 
through	efficient	processes	and	
decision making. It involves being 
satisfied	that	an	effective	and	
rigorous internal framework of 
systems and controls is in place 
which	clearly	defines	authority	
and accountability and promotes 
success whilst appropriately 
managing risk.

Human rights
Keller expects all employees and suppliers to 
adhere to international standards on human 
rights, including with respect to child and 
forced labour, land rights and freedom of 
association, among other elements. We take 
a zero-tolerance approach to slavery and 
human	trafficking	and	are	strongly	committed	
to ensuring that all employees, as well as the 
people who	work	on	our	behalf,	are	protected.	

Our full expectations are included in our Supply 
Chain Code of Business Conduct, modern 
slavery	and	human	trafficking	statement	and	
our new Human Rights Policy, which are available 
on our website. We conduct appropriate due 
diligence on our partners, and all of our suppliers 
are obliged to adhere to the principles set out 
in the Supply Chain Code of Business Conduct 
and policies.

Anti-bribery and corruption
Keller’s Anti-Bribery and Anti-Fraud Policy 
and whistleblowing procedures are designed 
to ensure that employees and other parties, 
including contractors and third parties, are able 
to report anonymously any instances of poor 
practice safely through an independent provider.

All reports received via this or any other reporting 
mechanism are thoroughly investigated and 
reported to the Audit and Risk Committee, which 
reviews each case and its outcomes. None of 
our	investigations	during	2023	identified	any	
systemic issues or breaches of our obligations 
under the Bribery Act 2010. The Anti-Bribery 
and Anti-Fraud Policy, which was reviewed and 
updated during the year, is supported by periodic 
audits and reminders.

Governance and oversight
We recognise that assurance over our business 
activities and those of our partners and 
suppliers is essential. In 2023 our employees 
completed mandatory training on competition 
law compliance, data privacy, the Code of 
Business Conduct, and prevention of facilitation 
of tax evasion. You can read more about our risk 
management framework and principal risks from 
page	36 onwards.

Tax strategy
We publish our tax strategy on our website 
and	are	committed	to	managing	our	tax	affairs	
responsibly and in compliance with relevant 
legislation. Our tax strategy is aligned to our 
Code of Business Conduct and Keller’s values 
and culture, and is owned and approved 
by the Audit and Risk Committee and the 
Board annually.

Keller’s ways of working

Our Code of Business Conduct (the ‘Code’) sets out clear and common 
standards of behaviour for everyone who works in and with Keller, as 
well as a framework to guide decision-making when situations aren’t 
clear-cut. It also ensures a positive culture that keeps us successful, 
operating in a way that we can all be proud of. It is a public statement 
of our commitment to high standards that tells others they can rely on 
our integrity.

The Code is supported by our Group policies, our modern slavery and 
human	trafficking	statement,	our	tax	strategy	and	our	Supply	Chain	
Code of Business Conduct, all of which are available on our website.

Our ethics and compliance programme is now in its eighth year of 
supporting our employees doing the right thing. The programme 
comprises training of our employees across the business on 
maintaining ethical and honest behaviour, respecting employees’ 
rights and	diversity,	and	staying	free	from	bribery	and	corruption.

Keller’s Code of Business Conduct and Group policies can  
be found at: www.keller.com under ‘How we work’.

Partnerships

At Keller, we recognise the 
importance of collaborating with 
organisations that understand 
our values and commitments, 
and the ways of working and the 
standards by which we operate. 
Partnering with these ‘like-minded’ 
organisations helps us drive change 
in our organisation and the wider 
geotechnical industry.

Industry partnerships
Many of our senior managers play key roles in 
the geotechnical professional associations and 
activities around the world.

In Europe, a number of employees are part of the 
European Federation of Foundation Contractors 
(EFFC), which is also chaired by Andreas Körbler 
from Keller. In Keller North America, employees 
are active participants in geotechnical 
engineering and construction trade groups, 
including the Deep Foundations Institute (DFI), 
ASCE/Geo-Institute and ADSC International 
Association of Foundation Drilling.  

Our North American engineers also hold 
leadership positions on multiple national 
technical committees (including committees on 
sustainability) and local and university chapters; 
many have served as members of the board of 
directors for these organisations. 

Finally, in AMEA, Keller plays an important role 
in the local professional societies, with Keller 
employees holding leading positions in multiple 
trade associations, including in ASEAN and India.

We also support trade conferences across our 
divisions, including the combined American and 
European trade conference.

Sustainability is an increasing focus in the 
industry. We work with a number of universities 
on sustainability initiatives, focusing on whole-
company	innovation,	specific	geotechnical	
products such as grouting and vibro stone 
columns, and key geotechnical projects.

We wrote the sustainability overview for the 
European Federation of Foundation Contractors 
and helped with the drafting of the American DFI 
sustainability guide.

We are also helping to compile sustainability best 
practice guides with the European and American 
trade associations.

Charitable partnerships
Our business units support a broad range of 
groups and charities, depending on what is 
most important to them locally. This may involve 
fundraising or donating money, time or skills.

Keller encourages its employees to support 
a range of charities, and has long committed 
to pledging to a charity the same value (up to 
£2,000 per annum) of any funds raised by an 
employee.

We again supported The Brilliant Breakfast 
in 2023 with an increased donation of nearly 
£15,000. Working with The Prince’s Trust, this 
UK initiative aims to change the lives of young 
women by helping them gain the skills needed 
to live, learn and earn. More information on this 
can be found in the report of the Sustainability 
Committee on page 108.

Activity challenge raises  
funds for Ukrainian colleagues

Our charitable arm – the KELLER 
Foundation (Fundacja KELLER) 
– continues to provide support 
to colleagues and their families 
affected by the war in Ukraine.

At	the	outbreak	of	the	conflict,	our	team	in	
Poland	acted	quickly	to	help	affected	Keller	
employees and their families. Since then, the 
foundation has helped 29 families relocate to 
Poland, Latvia and Estonia, and each month 
helps them pay for housing, food, clothes, 
heating and education.

To support the foundation and raise much-
needed funds, Keller ran an activity challenge for 
colleagues and their friends and families.

Using	the	Virgin	Pulse	health	and	wellbeing	
platform, teams from across the Keller world 
tracked activities such as running, cycling and 
gardening, for eight weeks. These were then 
converted to steps and distance travelled.

22,000	miles	and	44	million	steps	later,	Keller	
was delighted to donate £30,000 to the 
foundation in recognition of our colleagues’ 
commendable achievements.

“This	incredibly	successful	challenge	is	a	
wonderful gesture by the Keller community,” says 
Michał	Nowakowski,	HSEQ	Director	North-East	
Europe,	who	sits	on	the	foundation’s	board.	“The	
money raised will provide valuable assistance to 
these families for several more months.” 

“Unfortunately,	the	war	continues	and	while	it	
does, we want to be able to help the families. For 
many, we are the last resort.”

More information on the foundation, including 
how to donate and real stories from colleagues, 
can be found on Keller Poland’s website.

I’d like to say a big thank you to 
everyone for their support – I’m so 
proud to be part of such a fantastic 
and compassionate organisation.”

HSEQ Director North-East Europe

Dear shareholder
On behalf of the Board, I would like to introduce our Governance report for 
the year ended 31 December 2023. This report sets out our approach to 
effective corporate governance and outlines key areas of focus of the Board 
and its activities undertaken during the year as we continue to drive long-
term value creation for all our stakeholders. 

Board succession and diversity
The Board welcomed Annette Keller as a Non-executive Director and 
Chair Designate of the Remuneration Committee, joining on 1 December 
2023. Annette brings a diversity of experience and a new perspective, 
and is already making a valuable contribution. Annette’s biography is set 
out on page 89, and on page 111 Annette shares her initial thoughts on 
joining Keller.

Eva Lindqvist has announced her intention to retire from the Board and will 
stand down at the end of this year’s AGM, having served seven years as 
an independent Non-executive Director and five years as the Chair of the 
Remuneration Committee. Eva leaves the Board with our thanks and very 
best wishes.

We review the Board’s composition regularly and are committed to ensuring 
we have the best balance of skills and experience within the Board. We have 
made meaningful progress in achieving diversity, with 50% female Board 
members at year end (2023: 50%). As a Board, we have met the targets set 
out in our Board Diversity Policy and by the FTSE Women Leaders Review, 
the Parker Review and the targets specified in recent updates to the FCA’s 
Listing Rules, which we report against on page 73. The Board and the 
Nomination and Governance Committee will continue to drive the agenda 
of diversity, equity and inclusion across the Group.

Company purpose and culture
The Board is responsible for setting the tone from the top and promoting 
a culture which creates a positive work environment where everyone feels 
respected, motivated and able to thrive. Our employees are essential 
for the delivery of our strategic objectives and our continued success. 
Their feedback is critical to the Board and we continue to monitor our 
culture through surveys, town-hall sessions and formal and informal 
engagement activities.

Throughout 2023, we have 
delivered an outstanding 
performance. We remain 
focused on generating  
long-term value for our 
shareholders.”

Engagement with our stakeholders
Stakeholder engagement is critical to the long-term success of our 
business; the art of balancing different stakeholder views and needs in 
Board discussions and decision-making is key. The role of our designated 
workforce engagement director has been in place since 2017 and, 
supported by the Sustainability Committee, continues to be a successful 
way of ensuring that the Board appropriately considers the interests of 
employees in its deliberations and, in doing so, makes better decisions.

Last October, the Board attended a conference where it engaged with our 
Executive Committee and senior leadership team, and had the opportunity 
to gain increased insight into their progress against their strategic plans and 
local opportunities and challenges. 

During 2023, we commissioned an independent perception audit of a 
number of investment managers. We first initiated a perception audit in 
2021, the outcome of which was invaluable in affording the Board a deeper 
level of understanding of the views of our shareholders and potential 
investors whilst giving the executive management additional input as they 
formulate the strategy for the years ahead. The outcome of the 2023 audit 
will build upon the detailed action plan we put in place in 2021. 

Board evaluation
It is extremely important that the Board, its committees and individual 
Directors rigorously review their performance and embrace the opportunity 
to develop, where necessary. In 2023, we carried out an internal review of 
the effectiveness of the Board and its committees, facilitated by the Group 
Company Secretary and Legal Advisor, further details of which can be found 
on page 102. 

Looking forward
We will continue as a Board to maintain the highest standards of 
corporate governance across the Group, focus on delivery of our 
strategy and evaluate and improve all that we do across the Group. 

I encourage all our stakeholders to take every opportunity presented 
to engage with the company and I would welcome you to attend, 
and in any case vote at, the forthcoming AGM. If you wish to ask a 
question of the Board relating to this report or the business of the 
AGM, please feel free to do so by emailing the Group Company 
Secretary and Legal Advisor at secretariat@keller.com. We will 
consider and respond to all questions received and, to the extent 
practicable, publish the answers on our website.

As I look forward to the year ahead, I would like to take the 
opportunity to thank my colleagues on the Board and across  
the business for their continued hard work and dedication.

Yours faithfully

Peter Hill CBE

Effectiveness 

Directors and Directors’ independence
The Board currently comprises the Chairman, five independent 
Non-executive Directors (NEDs) and two Executive Directors. The names 
of the Directors at the date of this report, together with their biographical 
details, are set out on pages 88 and 89.

The NEDs constructively challenge and help to develop proposals on 
strategy and bring strong independent judgement, knowledge and 
experience to the Board’s deliberations. Periodically, the Chairman 
meets with the NEDs without the Executive Directors present. Apart 
from formal contact at Board meetings, there is regular informal contact 
between the Directors.

Keller continues to assess the independence of its Non-executive 
Directors on an annual basis in accordance with the UK Corporate 
Governance Code (the ‘Code’). This includes reviewing their tenure, 
any potential conflicts of interest, as well as assessing their individual 
circumstances to ensure that there are no relationships or matters 
likely to affect the judgement of the Non-executive Directors. Paula 
Bell, Annette Kelleher, Eva Lindqvist, Baroness Kate Rock and Juan G. 
Hernández Abrams are all considered to be independent NEDs. Their 
other professional commitments are as detailed on pages 88 and 89. 
Peter Hill CBE was independent at the time of his appointment as 
Chairman on 26 July 2016. Peter’s other professional commitments are 
as detailed on page 88.

All Directors are subject to election by shareholders at the first AGM 
following their appointment and to annual re-election thereafter, 
in accordance with the Code.

Directors’ conflicts of interests
Under the Companies Act 2006 (the ‘2006 Act’), a Director must avoid a 
situation where they have, or could have, a direct or indirect interest that 
conflicts, or possibly may conflict, with Keller’s interests. The 2006 Act 
allows Directors of public companies to authorise conflicts and potential 
conflicts, where appropriate, where the Articles of Association (the 
‘Articles’) contain a provision to this effect. The Articles give the Directors 
authority to approve such situations and to include other provisions to 
allow conflicts of interest to be dealt with. To address this issue, at the 
commencement of each Board meeting, the Board considers its register 
of interests and gives, when appropriate, any necessary approvals.

There are safeguards which will apply when Directors decide whether to 
authorise a conflict or potential conflict. Firstly, only Directors who have 
no interest in the matter being considered will be able to take the relevant 
decision and, secondly, in taking the decision, the Directors must act 
in a way that they consider, in good faith, will be most likely to promote 
Keller’s success. The Directors are able to impose limits or conditions 
when giving authorisation if they think this is appropriate. These 
procedures on conflicts have been followed throughout the year and the 
Board considers the approach to operate effectively.

Section 172 statement

Keller Group plc  Annual Report and Accounts 2023

As a Board, we have always taken decisions for the long term. Collectively and 
individually, our aim is always to uphold the highest standards of conduct. We 
understand that our business can only grow and be successful over the long 
term if we understand and respect the views and needs of our employees, 
customers and the communities in which we operate, as well as our suppliers, 
the environment and the shareholders to whom we are accountable.

As required by section 172 of the 2006 
Act, a director of a company must act in 
the way they consider, in good faith, would 
most likely promote the success of the 
company for the benefit of its shareholders. 
In doing this, the director must have 
regard, amongst other matters, to the:

• 

likely consequences of any decisions 
in the long term;
• 
interests of the company’s employees;
•  need to foster the company’s business 
relationships with suppliers, customers  
and others;
impact of the company’s operations  
on the community and environment;
•  company’s reputation for high standards  

• 

of business conduct; and

•  need to act fairly as between members  

of the company.

For more information see page 102

The Directors of Keller – and those of all UK 
companies – must act in accordance with 
a set of general duties. These duties are 
detailed in the 2006 Act and include a duty 
to promote the success of the company, 
As part of their induction, our Directors are 
briefed on their duties and they can access 
professional advice on these – either through 
the company or, if they judge it necessary, from 
an independent provider. 

Our Directors fulfil their duties partly through 
a governance framework that delegates 
day-to-day decision-making to employees 
of the company. 

The Board recognises that such delegation 
needs to be much more than simple financial 
authorities and should take into account 
the values and behaviours expected of our 
employees; the standards they must adhere 
to; how we engage with stakeholders; and how 
the Board looks to ensure that we have a robust 
system of control and assurance processes.

For more detail on our governance framework, 
see pages 97 to 99. Details about the principal 
decisions the Board made during the year  
can be found on page 93.

Shareholders

Delivering for our shareholders ensures that the business continues to be successful  
in the long term and can therefore continue to deliver for all our stakeholders.

How we engage

•  The Chief Executive Officer (CEO) and the Chief Financial Officer 
(CFO) meet with major shareholders following the preliminary 
results announcements to discuss a number of matters, including 
progress against the Group’s strategy. 

•  The CEO and the CFO have calls with major shareholders following 

the interim results announcements.

•  The CEO and the CFO have calls with major shareholders following 

the Group’s trading update announcements.

•  Following these announcements, analysts’ notes are circulated to 

the Board.

•  The Chairman and the Senior Independent Director have calls with 
shareholders to discuss Group performance and risk management 
throughout the year.

•  We have consistently either grown or maintained our dividend 

since listing. We have strong cash generation and a robust balance 
sheet which, together, support our ability to continue to sustainably 
increase the dividend.

Outcome

•  The investor relations section of our website provides information 
on the financial calendar, dividends, AGMs and other areas of 
interest to shareholders. Copies of annual reports and investor 
presentations are available to view and download. Shareholders can 
also register to receive ‘news alerts’ relating to the Group’s activities. 
During the year, we enhanced the ESG and sustainability section of 
the website to improve users’ access to information.

•  The Board uses the AGM as an opportunity to communicate with 
shareholders, who are invited to attend, ask questions and meet 
Directors prior to, and after, the formal proceedings. The Chairs 
of the Main Board Committees are present at the AGM to answer 
questions on the work of their committees. The results of the 
voting for the 2023 AGM can be found on our website.

•  For the second year running, we carried out an investor perception 
audit to obtain a deeper level of understanding of the views of 
shareholders and potential investors.

•  Keller is a stable business with a long-term track record.
•  Continued growth opportunities.
•  Consistent and sustainable dividend.

•  Transparency and clear communication.
•  Plan of action in place to address investor perception audit 

results.

Employees

Our people are our most valuable asset. We appreciate that they remain a key factor in our success and 
provide us with a competitive edge. We want them to be inspired and motivated, equipped with the right 
skills, tools and standards to be successful.

How we engage

•  During 2023, the Board continued its approach to engagement with 
the workforce led by Baroness Kate Rock, Keller’s designated Non-
executive Director for employee engagement matters.

•  Business unit leaders met in October 2023 at a company 

conference. The Board attended a number of activities during the 
conference. 

•  We communicate regularly with our employees through face-to-
face meetings, webcasts, our company intranet and newsletters 
and site and office visits. Site visits allow NEDs to feel the 
operational environment and enhance their understanding of 
employees’ experience of their working environment.

•  The Sustainability Committee considered feedback gathered 

through employee engagement surveys during 2023, which were 
conducted amongst five business units, the results of which can be 
found on page 106. 

Outcome

•  Local and global development opportunities.
•  Established development and training programme.
•  Long-term employment.

Inclusive, diverse and supportive environment.

• 
•  Plan of action in place to address employee engagement 

survey results.

improve on efficiently delivering a consistently high performance across all our strategic levers so as  
to meet our customers’ needs.

How we engage

Board composition, succession and evaluation

Board composition
The Board comprises the Non-executive Chairman, the Senior 
Independent Director, five independent NEDs and two Executive 
Directors. The Board appointed Annette Kelleher as independent NED on 
1 December 2023 as part of the Board’s succession planning. The Board’s 
individual biographies are detailed on pages 88 and 89.

Board diversity
Our Board Diversity Policy has been in place since January 2021.

In 2023, Keller’s Board of Directors had a 50% female share (2022: 43%). 

The selection of candidates to join the Board continues to be made 
based on merit and the individual appointee’s ability to contribute to the 
effectiveness of the Board, which in turn is dependent on the pool of 
candidates available. All appointments and succession plans will seek 
to promote diversity of gender, ethnicity, skills, background, knowledge, 
international and industry experience and other qualities.

Our commitment to equality and diversity and inclusion aligns with our 
values of integrity, collaboration and excellence and is underpinned by our 
Inclusion Commitments.

The Board is committed to promoting equality, diversity and inclusion in the 
boardroom, to ensure all are able to contribute to Board discussions, and 
aims to meet industry targets and recommendations wherever possible. 
This includes our objective of meeting the diversity targets recommended 
by the FTSE Women Leaders Review and the Parker Review.

The Board, supported by the Nomination and Governance Committee, is 
also committed to:

•  ensuring that the Board is comprised of a good balance of skills, 
experience, knowledge, perspective and varied backgrounds;

•  only engaging search firms who are signed up to the Voluntary Code 

of Conduct for Executive Search Firms;

•  ensuring that Board appointment ‘long lists’ will be inclusive according 

to the widest definition of diversity;

•  considering candidates for Non-executive Director Board 

appointments from a wide pool, including those with no listed 
company board-level experience; and
reporting annually on the diversity of the executive pipeline as well as 
the diversity of the Board.

• 

The annual evaluation of the Board effectiveness considers the 
composition and diversity of the Board.

We also aim to develop a strong pipeline of diverse candidates for executive 
Board roles and for the Executive Committee with a goal of ensuring that 
it is made up of an appropriate balance of skills, experience and knowledge 
required to effectively oversee the management of the company in the 
delivery of its strategy.

Board and Committee performance review and 
evaluation 2023
The annual Board evaluation provides the Board and its committees with 
the opportunity to consider and reflect on the quality and effectiveness of 
its decision-making, the range and level of discussion and for each member 
to consider their own contribution and performance.

The Group Company Secretary and Legal Advisor collated the individual 
responses, including analysis of themes and proposed actions. A detailed 
report, setting out the findings of the evaluation, was provided to the 
Chairman for consideration. The Group Company Secretary and Legal 
Advisor and the Chairman met to discuss the findings, with the resulting 
report being tabled to the Nomination and Governance Committee and 
Board in December 2023. 

In 2023, the review was facilitated internally by the Group Company 
Secretary and Legal Advisor, who is well placed as an independent sounding 
board to the process. 

Questionnaires were issued and each Director was also asked to 
complete an updated entry for the Board skills matrix, taking into 
consideration skills that had been strengthened through training and 
development over the previous year. Directors were also asked to 
highlight any additional skills that they felt may be beneficial for the Board 
to have amongst its members in order to discharge its duties effectively. 
Board members participated in comprehensive one-to-one meetings 
with the Chairman, to allow reflection on their personal responses to the 
questionnaire and discussion of matters relevant to boardroom culture, 
process and development. The Chairman’s performance evaluation was 
led by the Senior Independent Director.

The findings of the evaluation exercise were fully considered when making 
recommendations in respect of the appointment and reappointment of 
individual Directors, and included an assessment of their independence, 
time commitment and individual performance. The respective proposed 
2023 AGM Resolutions were considered and agreed by the Board. 

The Board will consider and agree the proposed actions arising from the 
evaluation for implementation and monitoring at its meetings in 2024. The 
Board will continue to oversee the progress made in relation to the agreed 
actions to ensure their timely completion. The Nomination and Governance 
Committee will also continue to play a key role in monitoring the actions 
relating to Board succession, composition, recruitment and induction.

An externally facilitated evaluation was conducted in 2021 and in 2022, 
and the next externally facilitated evaluation will be scheduled for 2024 
in accordance with the 2018 Code provision that the company should 
undertake an externally facilitated Board Effectiveness evaluation at least 
every three years.

Key areas identified in the review

Succession planning and Board composition 
Ensure process to enable the smooth succession of Non-executive 
Directors, including the Chairman, commences well in advance of 
scheduled retirements. 

Succession planning continues to be a key focus of the Board and a 
standing item on the agenda for Nomination and Governance Committee 
meetings. Robust succession plans will be put in place for all roles. 

Performance culture 
The Board members identified an opportunity to focus on a culture of 
delivery and accountability within the organisation. 

The deployment of high performance culture will be a key focus for 
the Board as it assesses Keller’s culture and engagement programme 
during 2024.

2024 Priorities
Notwithstanding the well-structured agendas which comprise an 
optimal mix of strategic and operational items, consideration should 
be given to scheduling key strategic and complex topics earlier on the 
Board agenda to ensure sufficient time for discussion and debate to 
align with the wider business planning and budgeting process. 

The Board forward agenda has been reviewed to ensure that: 

•  All matters are appropriately scheduled for discussion at future 

Board meetings; and 

•  Sufficient time is devoted to the discussion of strategic and 

innovative topics. 

Board development
On appointment, Directors are provided with induction training and 
information about the Group, the role of the Board and the matters 
reserved for its decision, the terms of reference and membership of the 
Board Committees and the latest financial information about the Group. 
This is supplemented by meetings with the company’s legal and other 
professional advisers, and, where appropriate, visits to key locations 
and meetings with certain senior executives to develop the Directors’ 
understanding of the business.

Throughout their period of office, Non-executive Directors are continually 
updated on our business, markets, social responsibility matters and other 
changes affecting the Group and the industry in which we operate, including 
changes to the legal and governance environment and the obligations 
on themselves as Directors. During 2023 the Board received externally 
facilitated training on human rights, and attended the Business Unit 
Leadership Conference in October.

AI-powered management reporting for the Board

Feedback from our Board 
evaluations in 2021 and 
2022 highlighted the need 
to improve how we frame 
discussion topics and a 
preference for more strategic 
discussions.

As a result, during 2023 we partnered with Board 
Intelligence to complete a review of Board and 
committee materials with the objective of finding 
opportunities to improve the quality of reporting. 
Reports prepared for our Directors are vital for 
helping them understand the daily workings of 
the business and take the necessary strategic 
actions for Keller’s continuous improvement.

Challenges identified during 
the review
•  Focus of board meetings
•  Coverage of strategy and risk
•  Clarity of papers
•  Backward-looking reports
•  Unclear drivers of performance
•  Lack of operational and non-financial 

information

Actions under way
To address the challenges identified,  
we are now in the process of implementing  
the following actions:

•  Rebalance the areas of focus and 

accompanying materials for the Board 
and committees.

•  Clarify and align expectations of Board 
and committee materials between the  
Non-executive Directors and the 
management team.

•  Establish the information that gives a clearer 
view of underlying business performance.

We have also introduced an innovative report 
writing tool called Lucia, by Board Intelligence. 
Lucia uses AI nudges to help senior leaders 
quickly craft crisp, easy-to-digest and 
insightful report in a format that drives better 
conversations and helps Directors make smarter, 
better-informed decisions. 

We are already seeing good results across a 
number of reports and we expect to be able to 
roll out the exercise further in the next year.

The Board and I 
have found the new 
reports to be clear, 
well-balanced and of 
high quality, giving 
us the right level of 
information we need 
to shape our thinking 
and actions.

Board composition, succession and evaluation continued

Information and support
The Board and committees are satisfied that they receive sufficient, 
reliable and timely information in advance of meetings and are provided 
with all necessary resources and expertise to enable them to fulfil their 
responsibilities and undertake their duties in an effective manner.

The Chairman and the Group Company Secretary and Legal Advisor keep 
under review the forward agendas for the Board and the content and 
construct of management papers to allow for greater focus by the Board as 
a whole on strategic matters and avoiding unnecessary operational detail.

For each Board and committee meeting, Directors are provided with a 
tailored Board pack in advance of the meeting, and we use an electronic 
system that allows the Board to easily access information, irrespective 
of geographic location. Directors regularly receive additional information 
between Board meetings, including a monthly Group performance update 
which includes carbon emissions reduction performance and progress on 
sustainability initiatives. If a Director is unable to attend a meeting, they are 
provided with all the papers and information relating to that meeting and 
have the opportunity to discuss issues arising directly with the Chairman 
and CEO.

Details on the identification and evaluation of risk, as well as on the 
management of project risk, can be found in the section headed Principal 
risks and uncertainties on pages 36 to 47. The key elements of the Group’s 
system of internal controls are explained in the Audit and Risk Committee 
report on page 118. The management of financial risks is described in the 
Chief Financial Officer’s review on page 35.

Compliance with laws and regulations
Compliance with laws and regulations both local and global is of extreme 
importance to the Board, including the minimisation of instances of 
non-compliance. Throughout the reporting year, the Group Company 
Secretary and Legal Advisor received reports from and met with members 
of divisional management to assess and understand the key challenges and 
opportunities faced in relation to legislative and regulatory developments 
within each jurisdiction of operation, which were subsequently reported to 
the Board for consideration.

No instances of non-compliance were identified throughout the year.

For more information on policy commitments in compliance with laws and 
regulations, please see our Non-financial and sustainability information 
statement on pages 82 and 83.

Accountability

Internal controls
The Board is ultimately responsible for the Group’s system of internal 
control and for reviewing its effectiveness. However, such a system is 
designed to manage, rather than eliminate, the risk of failure to achieve 
business objectives, and can provide only reasonable, not absolute, 
assurance against material misstatement or loss.

The Board confirms that there is an ongoing process for identifying, 
evaluating and managing the principal risks faced by the Group, which has 
been in place for the year under review and up to the date of approval of 
the Annual Report and Accounts. This process is regularly reviewed by the 
Board and accords with the guidance from the Financial Reporting Council.

Information included in
the Directors’ report

Certain information that fulfils the requirements of the Corporate 
governance statement can be found in the Directors’ report in the 
sections headed ‘Substantial shareholdings’, ‘Repurchase of shares’, 
‘Amendment of the company’s Articles of Association’, ‘Appointment 
and replacement of Directors’ and ‘Powers of the Directors’ and is 
incorporated into this Corporate governance section by reference.

Dear shareholder
On behalf of the Board, I am pleased to present the report of the 
Sustainability Committee for the year ended 31 December 2023, the 
first report since the merger of the previous Environment, and Social 
and Community Committees. I have been impressed by the energy and 
commitment of the Keller people during my first complete Board cycle 
with the Group. 

A new committee
During the year, the Environment and the Social and Community 
Committees were merged into the Sustainability Committee to reflect the 
growing importance of sustainability-led initiatives at Keller which the Board 
considers of key importance in supporting the delivery of the Group’s long-
term strategic objectives.

The new committee combined the resources of the previous committees, 
providing greater clarity and accountability on roles and responsibilities, 
easing decision making, and renewing our commitment to drive the 
sustainability agenda.

The Planet and People initiatives previously overseen by the Environment 
and Social and Community Committees respectively were continued by 
the new committee, although since its establishment, the committee has 
focused on developing its working cycle and practices to support the Board 
in its oversight of sustainability matters across the Group. 

TCFD reporting
During the year, the committee continued its focus on increasing the scope 
and quality of our disclosures under TCFD. 

We are pleased to report that we have made further progress in our third 
year of reporting under TCFD, having been able to broaden and quantify 
the findings of our scenario analysis modelling. As you can see on pages 
48 to 58, our disclosures have increased significantly to include scenario 
modelling for Europe, North America and part of AMEA. This demonstrates 
Keller’s ambition to better manage and mitigate our climate-related risks 
and opportunities, and our commitment to increased reporting for the 
benefit of our stakeholders. The committee is ideally placed to provide 
Board-level governance and scrutiny over strategic, climate-related topics.

For more information on the specific climate-related risks and 
opportunities, please see page 43 in the principal risks and uncertainties 
section of this report.

We are committed to driving our 
business in a sustainable way into 
the future while supporting the 
company’s overall strategy.”

Juan G. Hernández Abrams

Chair of the Sustainability Committee

Role of the committee
The role of the committee is to assist the Board of Directors in 
fulfilling its oversight responsibilities in relation to sustainability 
matters arising out of the activities of the Group.

Sustainability Committee report continued

Carbon reduction targets
Scope 1 emissions per £m revenue have decreased, with small 
improvements in the carbon efficiency of our operations.

Our culture

For Scope 1, we were excited to push several equipment decarbonisation 
initiatives during 2023. This included the launch of Keller’s first plug-in 
electric rig during the closing months of 2023. This enables us to work in low 
emission zones, designated quiet areas and closed space work sites. Whilst 
this new rig has not been deployed globally to Keller, it has nevertheless 
marked a momentous step towards the Group’s fleet decarbonisation. 
Additionally, the option of biofuels (HVO) as an alternative for clients was 
rolled out across several business units. Read more about the electric rig 
on page 13.

Keller has seen good engagement on Scope 2 activities, with the Group 
achieving its Scope 2 emissions reduction target. In 2023 we focused on 
implementing the findings from our previous energy audits across Keller’s 
three divisions, highlighting opportunities to save energy and money going 
forward. This saw the creation of Keller’s first net zero yard in the last 
quarter of 2023. Read more about the net zero yard on page 66.

How we work, shaped by  
our values and behaviours
Our track record of successful projects would not be possible 
without the passion, commitment and enthusiasm of the 9,500 
people who work for Keller worldwide. 

We have an outstanding company spirit that makes Keller a great 
place to work, and we aim to ensure that everyone feels respected, 
accepted, supported and valued.

Keller’s culture and engagement programme provides a structured 
way of getting and acting on employee feedback to continually 
improve the employee experience and drive better business 
performance.

Multiple initiatives are under way to quantify and reduce Scope 3 
emissions. The new ERP system is also being designed to have the 
capability to capture the necessary data for measuring Scope 3 
emissions. Further detail is available on page 67.

Employee engagement
The committee continued the excellent work previously undertaken by the 
Social and Community Committee by leading engagement by the Board 
and its committees with our workforce, making sure that the Directors 
understand and learn from the views of all our stakeholders. Opportunities 
for the Directors to learn from the views of our workforce arose in particular 
during the year when the Board met Divisional Presidents and Business 
Unit Leaders from across the organisation during a conference in October, 
where we learned about the progress they have been making and their 
local challenges. 

As part of Keller’s culture and engagement programme to drive better 
business performance and improve employee engagement, the Group 
invested in developing its own people to diversify the skills available 
in the internal talent pipeline, the aim being to achieve this through 
delivery of quality and consistent content across the Group via internally 
developed programmes.

To actively monitor the culture of the business, the Board and the 
committee, supported by the newly appointed Group HR Director and his 
team, will regularly review the results of employee engagement surveys, as 
well as insights from focus groups and site visits. Where consistent themes 
emerge, actions will be fed into the appropriate strategies to further 
strengthen our culture.

Looking forward

As industry leaders, we are on the right path at Keller on 
environmental and wider sustainability matters and will continue  
to drive for a more sustainable future.

Our priorities for 2024 will revolve around:

•  Embedding climate and social risks and opportunities in our 

overall strategy.

•  Horizon scanning on environmental and wider sustainability 

matters, in particular the reporting implications of the 
Corporate Sustainability Reporting Directive (CSRD). A multi-
functional CSRD working group has already been established, 
reporting to the Executive and the Sustainability Committees, 
and we intend to confirm our CSRD reporting approach in the 
next annual report. 

•  Supporting the company in its progress towards net zero, 

including Scope 3 emissions.

•  Assisting the Remuneration Committee in monitoring the 

impact of ESG targets on remuneration.

•  Continuing to engage employees on sustainability matters.

I look forward to meeting shareholders who attend our AGM this 
year to answer any questions on this report or on the committee’s 
activities. Shareholders are also encouraged to email their questions 
to the Committee Secretary at secretariat@keller.com. 

Juan G. Hernández Abrams
Chair of the Sustainability Committee 

Approved by the Board of Directors and authorised for issue on  
4 March 2024.

Keller Group plc  Annual Report and Accounts 2023

Sustainability is about action  
and at Keller this is in our DNA.”

Activities
Further detail on the committee’s activities can be found in the Planet, 
People and Principles sections of our ESG and sustainability report, starting 
on page 62, but I would like to highlight the following topics considered 
during the year:

•  Supported the Board in achieving its objective to continue the 

• 

reduction of Scope 1 and 2 emissions during the year.
Invested resources into developing a working programme to 
understand and assess Keller’s Scope 3 emissions. This has included 
bringing together leaders from across the Group from a variety of 
backgrounds, investment into new platforms to capture data relating 
to Scope 3 emissions, and awareness training across the organisation 
on the challenges facing Keller on this initiative.

•  Remained abreast of the development and implementation of the 
Inclusion Commitments, which continued to guide the delivery 
of people-related priorities across the Group. This included the 
review of an HR operating model which promotes transparent 
communication and project prioritisation to support Keller in achieving 
its strategic objectives.

•  Reviewed and promoted management’s proposal to invest towards 

internal talent and skills development, including performance 
management.

Corporate governance
The remit of the committee is set out in its terms of reference which are 
available on the Group’s website (www.keller.com) and on request from the 
Committee Secretary. During this financial year, the committee held formal 
meetings in July and December, with attendance at the meetings shown on 
pages 92 and 105.

The committee is comprised of the independent Non-executive Directors 
of the company, the Group Chairman and the CEO. The committee may 
invite members of the senior management team to attend meetings where 
it is felt appropriate, and the CFO, the Group Company Secretary and Legal 
Advisor, the Engineering and Operations Director, the Group HR Director 
and members of their teams regularly attend meetings. The Group Head of 
Secretariat is the Committee Secretary.

The Board delegates authority to the committee to manage, plan and 
mitigate Keller’s environmental and social-related risks and opportunities, 
and review relevant people, social and community policies and practices, but 
the Board maintains ultimate accountability for these. The Group Chairman 
is the Director responsible for ESG and sustainability matters. As such, the 
Board continued to monitor the efficacy, expertise and knowledge of the 
committee in executing the sustainability strategy throughout the year.  
Our organisational and reporting structure for climate governance, and  
how it fits within our governance framework, is set out in the TCFD section 
from page 48 onwards.

In addition, the committee’s performance, and that of its members, was 
evaluated internally in an exercise facilitated by the Group Company 
Secretary and Legal Advisor and overseen by the Group Chairman.  
More detail about this exercise can be found on page 102.

Privileged to partner with The Brilliant Breakfast

We are delighted to have supported 
The Brilliant Breakfast and The Prince’s 
Trust once again as Official Partner. 
These events were a great opportunity 
to share the work of this important 
cause, hear inspiring real-life stories, 
and of course raise funds.”

Kerry Porritt
Group Company Secretary and Legal Advisor

Keller partnered with The Brilliant Breakfast again in 
2023, hosting a number of events to raise funds for 
The Prince’s Trust programmes.

The Brilliant Breakfast is an annual, nationwide event raising money to 
support young women facing disadvantage and adversity live, learn and earn 
through The Prince’s Trust. Since launching in 2020, it has raised over £2.3m 
and helped over 1,900 young women participate in programmes run by 
The Prince’s Trust.

This time, as Official Partner, Keller committed to raise £5,000 on top of an 
existing £10,000 donation to the cause.

The first fundraising event saw the Group Head Office in the UK welcome 
representatives from The Prince’s Trust for a panel and networking session 
over breakfast. Hearing an inspiring young woman, Hannah Joseph, a 
Young Ambassador for the charity, talk about her experiences with their 
programmes was a particular highlight.

This was followed by a more musical effort, with two members of Group 
Head Office taking part in a charity ‘battle of the bands’ called Construction 
Rocks with their band ‘Zero Charm’. The event is an annual fundraiser for 
amateur musicians working in the construction industry. The band’s ticket 
sales and supportive donations were added to The Brilliant Breakfast fund.

Between the earlier company donation, the band’s commendable 
fundraising efforts (including match-funding from Keller) and the 
breakfast panel event, we raised nearly £15,000 for The Brilliant 
Breakfast and The Prince’s Trust in 2023.

Dear shareholder
Welcome to the report of the Nomination and Governance Committee 
for the year ended 31 December 2023.

The committee has continued to review the balance of skills on the Board 
as well as the knowledge, experience, length of service and performance 
of the Directors. During the year, we held two meetings, one in May and 
one in December. The attendance at both meetings is shown on pages 92 
and 109.

Board evaluation
It is extremely important that the Board, its committees and individual 
Directors rigorously review their performance and embrace the opportunity 
to develop, where necessary. In 2023, we actively progressed the areas of 
focus identified in 2021 and 2022, further detail of which can be found on 
page 102. We also conducted an internal review of the effectiveness of the 
Board and its committees, facilitated by the Group Company Secretary and 
Legal Advisor and overseen by the Group Chairman. 

Board composition
The committee’s activities during the year included:

•  Considering the number of Executive and Non-executive Directors 
on the Board, and whether the balance was appropriate to ensure 
optimum effectiveness.

•  Reviewing the balance of industry knowledge, relevant experience, 

skills and diversity on the Board.

•  Assessing and confirming that all the Non-executive Directors 

remained independent.

We are confident that each Director remains committed to their role and 
the Board continues to work well and benefits from an appropriate and 
diverse mix of skills and industry knowledge. Collectively, the Directors bring 
a range of expertise and experience of different business sectors to Board 
deliberations, and this encourages constructive and challenging debate 
around the boardroom table. Having a good mix of skills plays an important 
role in keeping the Board relevant and up to date with the market and 
best practice.

Welcome to Annette Kelleher 
In 2023 we were delighted to welcome Annette Kelleher as a 
Non-executive Director and Chair Designate of the Remuneration 
Committee. Annette has broad senior management experience in 
the international industrials sector, including change management, 
group development and transformation. The depth of experience 
she has in the international industrial sector, together with her people 
transformation skills, will bring a valuable and fresh perspective to our 
Board. She shares her initial thoughts on joining the Board on page 111.

Board diversity
Our commitment to equality, diversity and inclusion aligns with our values 
of integrity, collaboration and excellence and is underpinned by our 
Inclusion Commitments.

The Board is committed to promoting equality, diversity and inclusion in 
the boardroom, to ensure all are able to contribute to Board discussions, 
and aims to meet industry targets and recommendations wherever 
possible. This includes our objective of meeting the diversity targets 
recommended by the FTSE Women Leaders Review and the Parker Review. 
We also considered the new requirements under the Listing Rules and our 
disclosure is set out opposite.

Non-executive appointment and time commitment
When we make recommendations to the Board regarding Non-executive 
Director appointments, we consider the expected time commitment of the 
proposed candidate, and any other existing commitments, to ensure that 
they have sufficient time available to devote to the company.

Before accepting any additional commitments, Non-executive Directors 
discuss them with the Group Chairman, or, in the case of the Group 
Chairman himself, with the Senior Independent Director and the CEO. 
Board agreement is required to ensure that any conflicts of interest are 
identified and that the individual will continue to have sufficient time 
available to devote to the company.

committee, and no other person is entitled to be present at committee 
meetings. We may invite members of senior management to attend 
meetings where we feel it is appropriate, and the CEO, the CFO and the 
Group HR Director, along with external advisers, attended some of the 
meetings held during the year.

Our 2023 evaluation of the committee’s effectiveness concluded that, 
consistent with the Code and our own terms of reference, the committee 
was discharging its obligations in an effective manner.

In accordance with the requirements of the Code, all members of the 
Board, excluding Eva Lindqvist, will seek re-election at the AGM in May 2024. 
Annette Kelleher will seek election by shareholders as she joined the Board 
on 1 December 2023.

e

  What are your first impressions? 

I’ve had a very warm welcome to Keller by everybody I’ve met so far. It was 
immediately clear to me that the health and safety of people is something 
leaders take very seriously and in non-negotiable. I’m impressed with how 
much Keller has achieved during 2023 as well as the opportunities that are 
ahead. There’s a very strong sense of customer focus and doing the right 
thing for our clients and people. I think the depth and breadth of technical 
and engineering capabilities is striking. It’s great to see the diversity of 
local teams, and I hope I can support leadership in attracting more women 
into Keller engineering and technology where there are some fantastic 
career opportunities.

Companies like ours that have been around a long time are clearly able to 
adapt, and continuing to adapt, being agile and moving at pace is crucial 
for long-term success. Being open-minded and open to change is a 
real strength.

  What does your role as NED involve? 

I see myself firstly as a thought partner to management; someone who is 
supportive but will also constructively challenge. I have a responsibility to 
ensure alignment between our shareholders and management, to make 
sure we’re governed appropriately and to hold management to account, 
critiquing and contributing to strategy and its execution.

I’m also involved in four committees. Our Nomination and Governance 
Committee is responsible for appointing the most senior roles, including 
senior-level succession and also makes sure we have sight of talent across 
the organisation and have a sustainable pipeline. 

Our Sustainability Committee is fantastic as it’s all about doing what’s right 
for people and the planet in a way that enhances our strategy and delivers 
better outcomes for our customers. 

Our Audit and Risk Committee ensures our finances and accounts are 
correct and well governed, while our Remuneration Committee, which I’ll 
chair from May, sets and manages pay for our most senior leaders, as well as 
having oversight across our wider workforce policies.

  How will your experience and expertise help Keller?

I’m fortunate to have much experience of working in the industrial 
and technology sectors on a global scale. I believe my experiences in 
developing leadership, navigating change and enabling teams to drive 
transformation will all be relevant for Keller. My experience in change 
management and helping people through cultural change can really 
support Keller. 

  What are you looking forward to? 

I’m looking forward to supporting management across Keller shape further 
and implement its strategy to be an even more valuable company.

In particular I’m looking forward to helping leaders develop a high-
performance culture with a real focus on people. I’m excited about the 
opportunities for people to develop their careers within Keller and go 
on to achieve their aspirations. I want to ensure our people can see the 
career paths ahead of them and we build even more on Keller’s culture and 
outstanding reputation. I’d love to see more women enjoy a career in Keller, 
especially with such interesting technical challenges on a global scale.

There’s a lot to build on – to do what we do even better, to grow our 
leadership and to develop our people through the organisation. We’ll also 
continue to embrace our sustainability agenda and our very strong focus 
on health and safety. 

For me personally, I hope to help evolve our culture, respecting Keller’s 
strong heritage, and enabling it to adapt and out-perform for a 
sustainable future.

Annette Kelleher

Annette Kelleher joined Keller as a Non-
executive Director (NED) in December 2023. 
She’s also Chief Human Resources Director  
at sustainable technologies company 
Johnson Matthey, where she’s been since 
2013. Annette’s full biography is available  
on page 89. 

  What attracted you to Keller? 

When I started my research into Keller, I was quickly impressed by the 
technical aspects of what Keller does, particularly on a global scale. I was 
struck by the company’s heritage and fascinated to understand more. 
Once I met the Board and management team, I got an immediate sense 
of the culture and the importance of people within the company and the 
determination to do a great job for their customers. I found the management 
team to be really open and passionate about the business. 

It was important to me to join a company where I felt I could bring value and 
make a difference. Having worked extensively on a global scale, I believe 
with my experience I can really help Keller on the next stage of its journey. 
I’m thrilled to have the opportunity to be here and I’m excited about the 
opportunities I see for Keller.

  How was your induction? 

Soon after joining, I was straight in at the deep end, where my first Board 
meeting focused on reviewing the proposed budget for 2024. This was a 
fantastic opportunity for me to meet some of our key leaders and get some 
great insights into the challenges and opportunities in each of our regions. 
I’ve also had the chance to review some of our big projects and I’m starting 
to understand even more why Keller is such a leader in its space. I’ll be 
visiting sites in the UK and Germany soon, as well as Australia this year. I’m 
very keen to meet and talk with colleagues at the coalface of the business 
and really understand how our operations run.

I want to help enable a high-performance 
culture.”

Dear shareholder
On behalf of the Audit and Risk Committee, I am pleased to present our 
report for the financial year ended 31 December 2023.

We are also in the process of designing a Second Line of Defence Model 
across all key risk domains (including non-financial reporting, compliance 
and operational risks) to support our future assurance requirements, which 
includes the basis for the Board’s statement on internal controls.

We continue to monitor the ERP and finance transformation 
implementations to ensure that all relevant risks are considered and  
that the appropriate automated and manual controls are built into the 
system design. 

This has been another busy year for the committee and management has 
worked hard to drive improvements in the areas of risk, internal controls and 
financial reporting. We are proud of the progress that has been made during 
the year and remain confident in the actions that the management team 
has taken, and will continue to take, to ensure the maintenance of both 
high ethical and professional standards and resilient and effective controls 
throughout our organisation.

I hope that you find this report informative and can continue to take 
assurance from the work undertaken by the committee this year. We seek 
to respond to stakeholders’ expectations in our reporting and, as always, 
welcome any feedback from shareholders or other stakeholders.

I look forward to meeting shareholders who attend our AGM this year 
to answer any questions on this report or on the committee’s activities. 
Shareholders are encouraged to email their questions in advance to the 
Committee Secretary at secretariat@keller.com. 

Paula Bell
Chair of the Audit and Risk Committee

Approved by the Board of Directors and authorised for issue on  
4 March 2024.

This report is intended to provide shareholders with an insight into key 
areas considered, together with how the committee has discharged its 
responsibilities and provided assurance on the integrity of the 2023 Annual 
Report. This has included ensuring the 2023 Annual Report is aligned with 
the latest requirements and guidance from regulators, that it is fair, balanced 
and understandable and that all matters disclosed and reported upon meet 
the rapidly evolving needs of our stakeholders. In addition, the committee’s 
fundamental priorities include ensuring the quality and effectiveness of the 
external and internal audit processes and monitoring the management of 
the principal risks of the business.

My introduction sets out the key areas of focus for the committee during 
2023 (since our 2022 report) and to the date of this report.

The Group operates within a large, global and fast-changing environment, 
which requires an adaptive approach to assurance. Needless to say that the 
macro environment during 2023 remained challenging so it was important 
to ensure that the Group’s risk management and internal control systems 
operated effectively. Throughout the year the committee received regular 
updates from management on the strengthening of the financial control 
environment and systems of internal control. The internal audit plan has 
continued to be adjusted to adapt appropriately to the changing needs of 
the business.

Both the external and the internal audit processes were deemed to be 
effective. We are confident about the efficiency and quality of the process 
in place for the external audit of the 2023 year-end accounts. With regards 
to the internal audit, we conducted an independent external review of 
effectiveness during 2023 in line with the Institute of Internal Auditors (IIA) 
requirement to perform an independent assessment at least every five 
years. The outcomes of this review are outlined on page 117.

We continue to execute our implementation plan in preparation for the 
FRC’s proposed changes to the UK Corporate Governance Code and a 
future Board declaration on the effectiveness of risk management and 
internal control systems.

Given the fast-changing and uncertain corporate governance landscape 
in the UK, our focus has been on practical actions that enhance the 
Group’s control environment and especially the evidence maintained to 
demonstrate that our controls are operating effectively. We successfully 
implemented a number of initiatives following the fraud identified in the 
Austral Business Unit in Australia, including significantly enhancing our fraud 
risk identification and management programme. Progress against these 
initiatives was reported back to the committee, with the item becoming 
a standing item on the committee’s agenda during the year and in 2024.

Audit and Risk Committee report continued

Activities of the committee
The committee has an extensive agenda of items of business, aligned with the financial reporting cycle, focusing on the audit, assurance and risk 
processes within the business which it deals with in conjunction with senior management, the external auditor, the internal audit function and the 
financial reporting team.

The committee’s role is to ensure that management’s disclosures reflect the supporting detail provided to the committee or challenge them to explain 
and justify their interpretation and, if necessary, re-present the information. The committee reports its findings and makes recommendations to the 
Board accordingly.

The committee is supported in this role by using the expertise of EY. In doing so it ensures that high standards of financial governance, in line with the 
regulatory framework as well as market practice for audit committees going forward, are maintained.

Furthermore, PwC in their role as internal auditor contribute to the assurance process by reviewing compliance with internal processes.

The committee met four times during the year, with attendance at these meetings shown on pages 92 and 112, and considered the items of business 
shown in the table below.

The committee also reviewed the information presented in the Group’s preliminary announcement, the company’s processes for the preparation of the 
2023 Annual Report and the outcomes of those processes to ensure that we were able to recommend to the Board that the 2023 Annual Report satisfied 
the requirement of being fair, balanced and understandable.

The following processes are in place to provide this assurance:

•  Coordination and review of the Annual Report and Accounts performed alongside the formal audit process undertaken by EY.
•  Guidance issued to contributors at an operational level.
• 
•  Comprehensive review by senior management and external advisers to ensure consistency and overall balance.

Internal challenge and verification process dealing with the factual content of the information within the Annual Report and Accounts.

Audit and Risk Committee report continued

Significant audit risks and accounting judgements
In planning its agenda and reviewing the audit plans of the internal and external auditors, the committee has taken into account significant operational and 
financial issues and risks which may have had an impact on the company’s financial statements, internal controls and/or the delivery and execution of the 
company’s strategy (including changes in the nature and significance of some of the Group’s principal risks).

The committee focused on assessing whether management had made appropriate judgements and estimates in preparing the company’s financial 
statements, particularly with regard to the significant issues listed below. These issues were subject to robust challenge and debate between management, 
the external auditor and the committee.

The committee also reviewed detailed external auditor reports outlining work performed and any issues identified in respect of key judgements and 
estimates – in the independent auditor’s report on pages 148 to 158. The committee concluded there was no significant disagreement or unresolved issue 
that required referral to the Board.

Accounting for construction contracts

Significant issues considered

How the committee addressed these issues

There has been no change to the revenue accounting policy 
approved in 2019 and set out in the Group Finance Standard issued in 
2019. The policy has been in effect and operational throughout 2023 
and we have seen consistent application of the revenue recognition 
methodology applied in the businesses and across contract types.

During the year the committee monitored revenue recorded. This 
included material revenue related to contracts that were subject to 
settlement agreements and variation orders. The treatment 
recommended by management was in line with the approved policy 
and consistent with previous practice.

Significant judgements are still required to be made on contracts for 
which a degree of uncertainty remains after application of the 
methodology.

The committee considered these issues at all of its meetings during 
the year and, in particular, in December 2023 and February 2024 
when it agreed with management’s recommendations. The 
reasonableness of the recommendations made by management 
was also discussed with EY.

Carrying value of goodwill

Significant issues considered

How the committee addressed these issues

The Group tests goodwill annually, to assess whether any impairment 
has been suffered. This test is carried out in accordance with the 
accounting policy set out in note 2 to the financial statements. The 
Group estimates the recoverable amount based on value-in-use 
calculations. These calculations require the use of assumptions, the 
most important being the forecast operating profits, forecast 
reliability and the discount rate applied. The key assumptions used 
for the value-in-use calculations are set out in note 15 to the 
financial statements.

Provisioning

The committee considered the results of impairment tests of 
goodwill prepared by management at its meetings in December 2023 
and February 2024. Following discussion, consultation with EY and 
challenge, the committee agreed with the recommendations made 
by management. This resulted in an impairment charge recognised 
for the goodwill at Keller UK.

Significant issues considered

How the committee addressed these issues

Given the nature of the contracts undertaken by the Group, there is 
an inherent risk of claims being made against one or more of the 
Group’s businesses in relation to performance on specific contracts. 
These claims can include risks for which the Group has external 
insurance coverage. 

Recognition of liabilities for contract claims requires judgement and 
coordination between different Group functions. 

Expected credit losses

The committee received regular updates from the CFO and 
information relating to legal claims and assurance was provided by 
the divisional legal teams who reviewed the claims, with provisioning 
being assessed with input from divisional and Group finance.

Significant issues considered

How the committee addressed these issues

The recovery of trade receivables from customers in certain 
jurisdictions and circumstances can be challenging and subject to 
legal process, leading to uncertainty over the timing of cash inflows. 
Recognition of expected credit loss impairments for trade receivables 
and contract assets requires judgement.

The committee received regular updates from the CFO and 
information relating to expected credit losses was provided by the 
divisional finance teams who reviewed the open receivables balances, 
with provisioning being assessed with input from Group finance.

Details of the allowance for expected credit loss are set out in note 20 
to the statements.

Non-underlying items

Significant issues considered

How the committee addressed these issues

The disclosure of non-underlying items requires significant 
judgement given that no accounting standard defines specifically 
what items should or what items should not be presented as 
non-underlying.

The committee considered management’s presentation of 
non-underlying items at its meetings in July and December 2023, 
and February 2024. The reasonableness of the assumptions made 
by management was discussed with EY.

The committee agreed with the recommendations made by 
management.

Going concern

Significant issues considered

How the committee addressed these issues

Assessing the Group’s ability to meet its obligations as they fall due in 
the near term requires estimates and judgements to be made about 
the likely performance of the Group. The improved financial 
performance in 2023 combined with securing new debt facilities 
through issuing new notes in the US private placement market in 
August 2023 provide a strong platform for considering the Group’s 
ability to continue as a going concern. However, going concern 
remains a key focus for the committee and judgements and 
estimates have been made on prevailing market conditions in  
order to complete this assessment. 

Internal audit
The Keller internal audit programme is risk-based, ensuring appropriate 
coverage dependent upon the size of the entity and the perceived risks 
associated with that operation. It also includes theme-based audits to 
review adherence to Group policies across the organisation.

The programme carried out by PwC during the year consisted of 14 
operational entity audits and themed audits across 12 countries, which 
together represented approximately 39% of the Group’s budgeted revenue 
for the year.

The committee received and considered reports from PwC which detailed 
the progress against the agreed work programme and the findings. In the 
majority of reviews, following the successful update and deployment of the 
Group Finance Standards, findings were limited to the need for formalising 
maintenance of evidence of controls performed. Where more significant 
control issues were identified, we reviewed the findings, discussed the 
remediation plans with management and received updates on the progress 
of remediating the control deficiencies. None of the control deficiencies 
identified are significant in relation to the preparation of the 2023 Annual 
Report and Accounts.

The audits carried out during 2023 have been performed against 
updated control standards wherever they have been issued and any 
improvement actions aligned to them. The majority of control standards 
are now in place and embedded across the Group, helping to improve 
the control environment and enable early identification of potential 
control breakdowns.

Overall, progress has been made across business units and we have 
observed a demonstrably stronger control environment.

During the year, the committee completed an external effectiveness 
assessment of the internal audit function, which was performed by Deloitte. 
The work of the internal audit function was rated as fully conforming. It was, 
however, noted that there was an opportunity to refresh Keller’s three lines 
of defence model, with a plan for further improvement of the second line of 
defence to be executed in 2024.

The committee considered the judgements and estimates made by 
management in their assessment of the Group’s ability to continue as 
a going concern for the period through to the end of March 2025, a 
period of at least 12 months from when the financial statements are 
authorised for issue, at its meetings in July and December 2023, and 
February 2024.

External audit
The committee places great importance on ensuring there are high 
standards of quality and effectiveness.

EY was appointed by shareholders at the AGM held in May 2019, and 
reappointed in subsequent years. The lead EY partner during the financial 
year ended 31 December 2023 was Kevin Harkin, who had no previous 
involvement with the Group in any capacity prior to appointment. The 
lead EY partner from the financial year to 31 December 2024 will be 
Kevin Weston. 

The committee considered the effectiveness and quality of the external 
audit process and of EY as external auditor. This review included 
consideration of comprehensive papers from both management and the 
external auditor, and meetings with management in the absence of the 
external auditor. It considered matters including: the competence of the 
key senior members of the team and their understanding of the business 
and its environment; the planning process; effectiveness in identifying key 
risks; technical expertise displayed by the auditor over complex accounting 
matters; communicating and resolving audit issues; timeliness of the audit 
process; cost and communication of issues and risks to management and 
the committee.

There are a number of checks and controls in place for safeguarding 
the objectivity and independence of EY. These include open lines of 
communication and reporting between EY and the committee and, when 
presenting their ‘independence letter’, EY discuss with the committee their 
internal process for ensuring independence.

We assess the effectiveness of the external audit process on an ongoing 
basis, paying particular attention to the mindset and culture, skills, character 
and knowledge, quality control and judgement of the external audit firm in 
their handling of key judgements, responsiveness to the committee and 
in their commentary where appropriate on the systems of internal control. 
By way of an example, please refer to the Independent auditor’s report on 
pages 148 to 158 where EY’s actions to mitigate the risk arising out the 
financial reporting fraud in Austral are explained.

Audit and Risk Committee report continued

The Group aims to continuously strengthen its processes, with the 
involvement of the committee, to ensure these processes are embedded 
throughout the organisation. During 2023, we continued to support 
management in their efforts to enhance the system of internal controls, 
defining the following priorities and receiving updates on their progress:

•  Continued development of the Group’s financial control framework 
and setting of minimum control standards for all areas of financial 
reporting and operational finance.

•  Monitoring of the implementation of the monthly sign-off checklist 
at each business to certify that accounting controls have been 
performed/complied with for the month.

•  Review of internal control questionnaires, to identify common areas 

for improvement as well as to address specific risks and direct 
assurance efforts.

•  Mapping of the Group’s control environment to assess controls 

maturity across all functions within the Group.

•  Successfully implementing a governance, risk and compliance (GRC) 

tool to support the assessment, monitoring and reporting on risks and 
internal controls.

Although we review the Group’s system of internal controls, any such 
system can only provide reasonable and not absolute assurance against any 
material misstatement or loss.

The committee reviewed and challenged the output of management’s 
assurance map to assess controls maturity in the context of the 
various programme change initiatives under way such as ERP, finance 
transformation and PPM. 

Controls response plan
As reported last year and elsewhere in this report, following the financial 
reporting fraud in the Austral Business Unit, a controls response plan was 
developed that covered both the business unit and the Group. Deloitte was 
engaged to assist in the initial review and plan implementation. The majority 
of the actions have been completed and there are ongoing projects that will 
continuously improve controls, including:

•  Second line of defence assurance.
•  Project management controls through the new PPM standard.
•  Finance transformation.

Deloitte’s engagement, following the initial review, involved assessing 
the maturity and robustness of the Group’s minimum control standards 
across a sample of legal entities and performing an effectiveness review of 
the internal audit function. Both reviews highlighted the need for Keller to 
urgently review the organisation’s governance, risk and assurance design 
across the three lines of defence, with priority focused on the second line of 
defence, to help reduce the likelihood of control breakdowns.

This is an extensive piece of work which has already commenced and we will 
report further next year.

External audit continued
We hold regular private meetings with the external auditor, during which 
we discuss:

•  How the auditor has identified and addressed potential risks to the 

audit quality.

•  The controls in place within the audit firm to identify risks to audit 

quality.

•  The level of challenge the auditor has discussed with the management 

team and their confidence on the control landscape.

•  Whether the auditor has met the agreed audit plan and how it has 

responded to any changes that have been required.

•  Feedback from key people involved in the audit.
•  The content of the auditor’s management letter.

A detailed assessment of the amounts and relationship of audit and non-
audit fees and services is carried out each year and we have developed 
and implemented a policy regulating the placing of non-audit services 
to EY. This should prevent any impairment of independence and ensure 
compliance with the updates to the Code and revised Auditing and Ethical 
Standards with regard to non-audit fees. Any work awarded to EY, other 
than audit, with a value in excess of £50,000, requires the specific pre-
approval of the Board. In 2023, non-audit-related fees paid to EY were less 
than 5% of the total audit fee. These relate to the half-year report review 
and are considered to be permitted services. The breakdown is available in 
note 6 of the accounts on page 177.

The external audit contract is put out to tender at least every 10 years. 
As part of the review of the effectiveness and independence of the 
external auditor, we recommend the reappointment of EY for the year 
ending 31 December 2024. The lead EY partner from the financial year to 
31 December 2024 will be Kevin Weston.

We confirm compliance with the provisions of the Statutory Audit Services 
for Large Companies Market Investigation (Mandatory Use of Competitive 
Tender Processes and Audit Committee Responsibilities) Order 2014.

Risk management and internal control
The committee has a key role, as delegated by the Board, in ensuring 
appropriate governance and challenge around risk management. We also 
set the tone and culture within the organisation regarding risk management 
and internal control.

Further information on the Group’s risks can be found on pages 36 to 47.

The system of internal control is designed both to safeguard shareholders’ 
investment and the Group’s assets, and to facilitate the identification, 
evaluation and management of the significant risks facing the Group. Key 
elements of the Group’s system of internal control include:

•  An experienced and qualified finance function which regularly 

assesses the possible financial impact of the risks facing the Group.
•  Monthly dashboard packs reviewed by the Executive Committee and 

the Board.

•  Detailed business unit budget reviews with updates provided to the 

Board.

•  Regular reports to the Board on health and safety issues.
•  Regular visits to operating businesses by head office and divisional 

directors.

•  Annual completion of internal control questionnaires by business unit 

management.

•  Reports to the committee by PwC on the findings of their internal 
audit reviews of the controls, processes and procedures in place at 
each of the Group’s in-scope units.

Corporate governance
The committee’s terms of reference, which were reviewed during the year, 
are available on our website (www.keller.com) and on request from the 
Committee Secretary.

It is intended that the committee is comprised of at least three members, 
all of whom are independent Non-executive Directors of the company 
with the necessary range of relevant sector, financial and commercial 
expertise to enable the committee to fulfil its terms of reference. They do 
so by providing independent and robust challenge to management and 
our internal and external auditors, and ensuring there are effective and high 
quality controls in place and appropriate judgements are taken. The Code 
requires the inclusion of one financially qualified member (as recognised by 
the Consultative Committee of Accountancy Bodies) with recent financial 
expertise. Currently, the Committee Chair fulfils this requirement.

We invite the Group Chairman, the CEO, the CFO, the Group Financial 
Controller, the Group Head of Risk and Internal Audit, the Group Company 
Secretary and Legal Advisor, the company’s external auditor, EY, and PwC in 
their role as internal auditor, to all meetings. The Group Head of Secretariat 
is the Committee Secretary.

On two occasions, the committee met privately with EY without 
management being present and we also met twice during the year 
with PwC and the Group Head of Risk and Internal Audit without 
management present.

In line with best practice, the committee conducted an effectiveness review 
of the business covered during the year against its terms of reference.

Collectively, the committee has the competence relevant to the sector 
as required by the provisions of the Code, as well as the contracting and 
international skills and experience required to fully discharge its duties. The 
committee is authorised by the Board to seek any information necessary 
to fulfil these duties and to obtain any necessary independent legal, 
accounting or other professional advice, at the company’s expense.

Looking forward

In 2024 our priorities will be:

•  Monitoring improvement actions identified in 2023, in 

particular the detailed action plan that will deliver continuous 
improvement to our second line of defence processes in line 
with our assurance strategy.

•  Monitoring the progress of the finance transformation project. 
•  Further developing the approach to fraud risk assessment 

utilising the GRC tool that was successfully deployed in 2023.

•  Continued review of the cyber security risk mitigation plan. 
•  Monitoring the implementation of PPM, supported by both 

internal and external independent assurance activity.
•  Monitoring the delivery of the ERP system, supported by 

independent assurance activity.

Keller Group plc  Annual Report and Accounts 2023

Anti-bribery and anti-fraud
The committee is responsible for reviewing the Group’s procedures 
for detecting fraud, and the systems and controls for preventing other 
inappropriate behaviour with a financial impact. Any instances of fraud 
or suspected fraud are reported directly to the Group Head of Risk and 
Internal Audit and the Group Company Secretary and Legal Advisor, or 
anonymously via the Group Whistleblowing hotline. All reports of suspected 
or actual fraud are treated with confidentiality and thoroughly reviewed 
and assessed. 

During 2023 the Anti-Bribery and Anti-Fraud Policy was independently 
reviewed and updated. We also ran a series of fraud risk workshops with key 
members of management across the business to ensure material fraud 
risks are identified and effective controls put in place to mitigate them.

During the year, the committee was kept fully apprised in regular updates on 
the progress and findings of investigations of cases of alleged fraud and any 
remedial actions taken. Nothing substantial was uncovered.

Our response to the UK Corporate Governance Reform
Our UK Corporate Governance Reform implementation plan continues to 
be revised to ensure that it is fit for purpose and in line with emerging FRC 
and Government requirements. In 2023, a major component of this plan 
involved investment in key systems to facilitate effective risk management, 
including the implementation and rollout of a Governance, Risk and 
Compliance tool, to bring together all aspects of our risk management 
and internal controls management processes. We also implemented a 
segregation of duties monitoring tool to ensure that we maintain effective 
segregation of duties within our current ERP landscape and to also assist 
with appropriate role design within our future global ERP. 

Following the fraud identified in the Austral Business Unit, the Group 
implemented a number of initiatives, including reviewing and updating 
the Anti-Bribery and Anti-Fraud Policy and running a series of fraud risk 
workshops with key members of management to ensure that all material 
fraud risks are identified and captured and effective controls are in place 
to mitigate those risks. The Group Head Office team worked closely with 
the new Austral CFO and her team to redesign and document the material 
finance processes and controls and to implement remediation activities 
identified from the various external reviews commissioned in response to 
the fraud. These external reviews also identified the need to enhance our 
second line of defence capabilities, especially around internal controls over 
financial reporting and project performance management controls. Design 
and rollout of a second line of defence model will be a key area of focus for 
the Group throughout 2024 and other areas of risk, including non-financial 
reporting, compliance and operations, will also be included to address the 
FRC’s proposed requirement that the Board disclose the basis for their 
statement on internal controls. 

Interaction with the FRC
During the year, the FRC reviewed the company’s Annual Report and 
Accounts for the year ended 31 December 2022 in accordance with Part 
2 of the FRC Corporate Reporting Review Operating Procedures. This 
resulted principally in requesting further information in respect of expected 
credit losses for trade receivables and contract assets, as well as minor 
observations on other areas of the accounts.

The Group responded fully to the matters raised in the correspondence 
and as a result has restated the disclosure of the allowance for expected 
credit losses in note 20 of this year’s accounts. The FRC’s enquiry did not 
result in any restatement of the primary statements reported for the 2022 
financial year.

The Chair of the Committee has been involved in reviewing the Group’s 
response to the points raised and is satisfied that the matters have been 
addressed effectively, with additional or amended disclosures adopted in 
this year’s Annual Report and Accounts.

Dear shareholder
On behalf of the committee, I am pleased to provide an overview of 
Executive Director remuneration for the year ended 31 December 2023.

2023 business performance and incentive outcomes
Keller delivered a record performance in 2023. Underlying operating profit 
increased to £180.9m, up 67% at constant currency. Underlying diluted 
earnings per share increased by 53% to 153.9p per share (2022: 100.7p per 
share). Net debt (on a bank covenant IAS 17 basis) decreased by 33% to 
£146.2m, equating to a net debt/EBITDA leverage ratio of 0.6x (2022: 1.2x).

The targets for the 2023 annual bonus for executive management were 
set by the committee in February of last year and remained unchanged 
throughout the year. When determining the bonus outcome, the 
committee considered overall company performance over the period, 
weighing the successful execution of the strategy and continued growth of 
the Group against the wider macroeconomic environment.

The annual bonus payments for 2023 reflect the very strong operational 
and financial performance of the Group. The financial measures, Group 
profit before tax and net debt, paid out in full. There was progress against 
the corporate objectives and the Executive Directors achieved 9% out 
of a possible 30% maximum. Overall, the annual bonus outturn was 79% 
of maximum.

After considering all the relevant factors for the 2023 bonus, the 
committee’s view was that the outcome was fair and appropriate from 
both a performance perspective and also taking into account the wider 
stakeholder experience. Therefore, no discretion was exercised.

The performance of the PSP granted under the company’s Long-Term 
Incentive Plan 2018 (LTIP) to executives in 2021 and vesting in March 2024 
was improved from the previous PSP cycle. The operating profit margin and 
ROCE targets were almost fully met during the performance period, with 
the EPS target being met in full and TSR vesting at maximum. Overall, the 
2021 LTIP awards vested at 95.6% of maximum.

The committee carefully considered the vesting levels of the 2021 award, 
with additional reference to both the shareholder and wider workforce 
experience. It also specifically considered share price movements and was 
satisfied that there had been no inappropriate windfall gains over the period. 

The committee determined that the LTIP outcome fairly and 
appropriately reflected performance over the three years and no 
discretion was exercised.

2023 wider workforce
Salary increases awarded across the business in 2023 were weighted to the 
company’s lower paid employees and a number of one-off payments were 
made to support employees through the cost of living crisis. 

Shareholder engagement and consultation
In October 2023, we engaged with our top 20 shareholders as well as the 
Investment Association, ISS and Glass Lewis to explain our proposed 
changes to the Policy as part of the normal three-year renewal cycle. 

During 2023, the committee reviewed the annual bonus plan arrangements 
in place for the extended leadership team, comprising our global senior 
management teams at the level below the Executive Committee, and 
approved a new structure proposed by management to provide general 
alignment and consistency in the structure, performance measures 
and weighting of performance pay across the Group. Employees now 
have a profit and cash target one level up from their area of operation to 
encourage collaboration and alignment, together with a number of shared 
corporate and/or personal objectives. 

The vast majority of our largest shareholders were supportive of the 
proposals put forward. On that basis, the committee has decided to 
proceed with the proposed changes in our 2024 Policy which will be put to a 
binding shareholder vote at our AGM in May 2024 and we wrote to our major 
shareholders and the main proxy voting bodies in January 2024 to follow up 
with our final proposals.

The committee is grateful to shareholders for the time they have given to 
the consultation process and the feedback provided, which has helped 
facilitate a more robust decision-making process.

2024 salary review
Salary increases for UK-based employees across the Group were generally 
around 6.5%, effective 1 January 2024. The committee has considered 
the impacts of rising inflation and cost of living challenges with regard to 
the wider workforce and has positively noted management’s efforts to 
provide additional security and robustness of earnings to those particularly 
impacted in the Group.

Michael Speakman, CEO, and David Burke, CFO, were awarded salary 
increases of 4.5%. As additional context, the CEO and CFO are already 
aligned with the wider workforce pension rate of 7% of salary.

Key changes to the Remuneration Policy (the ‘Policy’)
A number of changes were made to the Policy in 2021, bringing it in line with 
the UK Corporate Governance Code and the wider business environment. 
The 2021 Policy introduced a number of best practice governance features, 
some of which were already in operation, as summarised below: 

• 

Introduction of a two-year post-employment shareholding 
requirement for Executive Directors. 

•  Discretion for the committee to override formulaic outcomes in the PSP.
•  Malus and clawback policy.
•  Mitigation measures for Executive Director leavers written into current 

service contracts. 

•  Settlement of deferred bonus and dividend equivalents in shares and 

not cash. 

•  Alignment of Executive Director pensions to the general workforce. 

We also took the opportunity to refresh the performance metrics in our 
PSP. The 2021 Policy was approved by 90.2% of shareholders. 

In the context of evolving market practice since the approval of Keller’s 
2021 Policy, the committee has reviewed its policy and proposes the 
following changes:

• 

• 

Increasing the maximum opportunity available under the PSP from 
150% to 200% of salary. The committee believes this increase is 
appropriate in the context of market practice and competitiveness 
and to ensure the policy remains fit for purpose over the next three 
years. In 2023, the CEO received an LTIP award of 150% of base salary 
and the CFO received an LTIP award of 125% of base salary. The 
committee intends to grant 2024 LTIP awards at the same level.
Introducing an additional trigger of ‘corporate failure’ under Keller’s 
malus and clawback policy, for good governance and in line with 
emerging market practice. 

Year ahead: 2024 annual bonus plan and LTIP metrics
Management’s focus continues to be on driving value by focusing on, and 
investing in, our key markets and the sustainability of operating profits and 
enhanced margins, whilst maintaining a robust balance sheet.

In 2022, the company committed to ambitious net zero targets for all 
three of our emission scopes which will culminate in carbon neutrality 
by 2050 at the latest, and a Scope 2 reduction target formed one of 
management’s corporate objectives for 2022 and 2023. Recognising 
the continued importance of achieving these goals, we have agreed a 
Scope 1 reduction target and a further Scope 2 reduction target to be 
included in management’s corporate objectives for 2024. Further detail 
on the 2024 corporate objectives will be disclosed in the 2024 Annual 
remuneration report.

The four LTIP measures agreed in 2021 continue to support the delivery of 
the strategy and are therefore carried forward into 2024. Together with the 
targets for the LTIP for the year ahead, the measures are disclosed in the 
this Directors’ remuneration report. See page 141 for further details.

2024 Annual General Meeting (AGM)
We very much hope that you will support our 2024 Policy and 2023 Annual 
remuneration report at the AGM in May. I will be available at the AGM to 
answer any questions you may have about our work. Please also feel free to 
email your questions to the Group Company Secretary and Legal Advisor at 
secretariat@keller.com and we will respond to them directly.

The 2024 AGM will be my last at Keller as I have decided to step down after 
seven years on the Board. It has been a pleasure to serve on your Board 
and I wish Annette Kelleher great success as she takes over as Chair of the 
Remuneration Committee.

Remuneration in context

The committee sets the Remuneration Policy for Executive Directors and other senior  
executives, taking into account the company’s strategic objectives over both the short  
and the long term and the external market.

The committee:
•  addresses the need to balance risk and reward;
•  monitors the variable pay arrangements to take account of risk levels, 
ensuring an emphasis on long-term and sustainable performance; and

•  believes that the incentive plans are appropriately managed and 
that the choice of performance measures and targets does not 
encourage undue risk-taking by the executives so that the long-term 
performance of the business is not compromised by the pursuit of 
short-term value.

The plans incorporate a range of internal and external performance metrics, 
measuring both operational and financial performance over differing and 
overlapping performance periods, providing a rounded assessment of 
overall company performance.

Linkage to all-employee pay
The committee reviews changes in remuneration arrangements in the 
workforce generally as we recognise that all our people play an important 
role in the success of the company. Keller is committed to creating an 
inclusive working environment and to rewarding our employees throughout 
the organisation in a fair manner. In making decisions on executive pay, the 
committee considers wider workforce remuneration and conditions to 
ensure that they are aligned on an ongoing basis.

As part of our commitment to fairness, we have a section in this report (see 
ESG and sustainability on page 70) which sets out more information on our 
wider workforce and our diversity initiatives. We recognise there is always an 
opportunity to improve in relation to these issues.

Shareholder views
The committee engages proactively with the company’s major 
shareholders and is committed to maintaining an open dialogue. The 
committee reviews any feedback received from shareholders as a result of 
the AGM process. Committee members are available to answer questions 
at the AGM and throughout the rest of the year. The committee takes into 
consideration the latest views of investor bodies and their representatives, 
including the Investment Association, the Pension and Lifetime Savings 
Association and proxy advice agencies such as Institutional Shareholder 
Services.

Remuneration principles
We strongly believe in fair and transparent reward throughout the 
organisation and when making decisions on executive remuneration the 
committee considers the context of wider workforce remuneration. This 
section shows how the 2018 Code is embedded in our remuneration 
principles and how they are cascaded throughout the organisation. The 
table below and on the following page shows how the policy is aligned with 
the factors set out in Provision 40, and how our principles and policy are 
aligned with the 2018 Code. During 2024 we will work to align our policy with 
the 2024 Code. 

Our Purpose: Building the foundations for a sustainable future

Embedding our purpose and 
vision in our remuneration 
guiding principles

•  Support our purpose, values and our 

wider business goals.

•  Drive long-term sustainable 

performance for the benefit of all 
our customers, shareholders and 
wider stakeholders.

•  Be simple, transparent and easily 

understood by internal and external 
stakeholders.

•  Attract, motivate and retain 

all our employees with diverse 
backgrounds, skills and capabilities.

How we address the requirements under Provision 40

Cultural alignment and proportionality
•  The committee ensures that the overall 
reward framework embeds our purpose 
and values.

Simplicity, clarity and predictability
•  The committee ensures the highest 

standards of disclosure to our internal and 
external stakeholders.

•  The committee reviews the executive 

reward framework regularly to ensure it 
supports the company’s strategy.

•  The committee makes decisions on 
executive pay in the context of all 
employees and the external environment.

Proportionality and risk
•  A significant proportion of remuneration is 
delivered in variable pay linked to corporate 
performance.

•  Performance measures/targets for 

incentives are objectively determined.
•  Outcomes under incentive plans are based 
on holistic assessment of performance.

Cultural alignment and risk
•  The committee ensures that a significant 
portion of reward is equity-based and 
thereby linked to shareholder return.
•  Executive Directors are required to build 
significant personal shareholdings in the 
company and this is regularly monitored 
by the committee.

Clarity
•  The committee ensures that the Executive Directors are provided with a remuneration 

opportunity which is competitive against companies of a similar size and complexity, with a 
strong emphasis on the variable elements.

Alignment of the Policy to the Provisions of the 2018 Code

Clarity
The company’s performance remuneration is based on supporting the implementation of the company’s strategy measured through KPIs which 
are used for the annual bonus and LTIP. This provides clarity to all stakeholders on the relationship between the successful implementation of the 
company’s strategy, including its sustainability framework, and the remuneration paid.

Simplicity
The Policy includes the following:

•  setting defined limits on the maximum awards which can be earned;
• 

requiring the deferral of a substantial proportion of the incentives in shares for a material period of time, helping to ensure that the 
performance earning the award was sustainable, and thereby discouraging short-term behaviours;

•  aligning the performance conditions with the agreed strategy of the company as well as our sustainability and net zero carbon ambitions;
•  ensuring a focus on long-term sustainable performance through the LTIP; and
•  ensuring there is sufficient flexibility to adjust payments through malus and clawback and an overriding discretion to depart from formulaic 
outcomes, especially if it appears that the behaviours giving rise to the awards are inappropriate or that the criteria on which the award was 
based do not reflect the underlying performance of the company.

Predictability
Shareholders are given full information on the potential values 
which can be earned under the annual bonus and LTIP plans on their 
approval. In addition, all the checks and balances set out above under 
‘Risk’ are disclosed at the time of shareholder approval.

Proportionality
The company’s incentive plans clearly reward the successful 
implementation of the strategy and our environmental ambitions, and 
through deferral and measurement of performance over a number 
of years ensure that the executives have a strong drive to ensure that 
the performance is sustainable over the long term. Poor performance 
cannot be rewarded due to the committee’s overriding discretion to 
depart from the formulaic outcomes under the incentive plans if they 
do not reflect underlying business performance.

Alignment to culture
A key principle of the company’s culture is a focus on our stakeholders and their experience; this is reflected directly in the type of performance 
conditions used for the bonus. The focus on long-term sustainable performance is also a key part of the company’s culture. In addition, the 
measures used for the incentive plans are measures used to determine the success of the implementation of the strategy.

REM

Remuneration Policy report

The Remuneration Policy (the ‘Policy’) is set out in this section

This Policy will be put to shareholders for approval at the AGM to be held on 
15 May 2024. The Policy is intended to apply, subject to shareholder approval, 
for three years from 1 January 2024. Where a material change to this Policy 
is considered, the company will consult with major shareholders prior to 
submitting to all shareholders for approval. The Policy will be displayed on 
the company’s website (www.keller.com) following the 2024 AGM.

Summary of decision-making process
As described in the Annual statement from the Chair of the Remuneration 
Committee, the committee engaged with its major shareholders in 2023 
as part of its review of the executive remuneration policy. We wrote to 
20 of our largest shareholders and the major shareholder representative 
bodies in October 2023 to consult on the development of our executive 
remuneration approach and, having considered the feedback, we wrote 
to them again in January 2024 to explain the outcome of the review, the 
changes proposed and associated rationale.

Shareholders were offered the opportunity to discuss the proposals with 
the Committee Chair and the Group Company Secretary and Legal Advisor 
on both occasions and overall we were encouraged by the number of 
shareholders who took the time to respond and engage and are satisfied 
that, having taken into account both supporting views and key concerns, 
we have developed an appropriate way forward.

In addition to the specific feedback received from our consultation with 
major shareholders, we also considered input from the management 
team and our independent advisers, as well as latest market practice and 
corporate governance developments. To manage any potential conflicts 
of interest arising, the committee ensured that no individual was involved 
in discussions on their own remuneration arrangements and all changes 
proposed aligned to the business’ core strategy and values.

In reaching its decisions, the committee also considered the following principles as 
recommended in the 2018 UK Corporate Governance Code.

Clarity

Predictability

The policy is designed to allow our remuneration arrangements 
to be structured such that they clearly support, in a sustainable 
way, the financial and strategic objectives of the company. The 
committee remains committed to reporting on its remuneration 
practices in a transparent, balanced and understandable way.

The committee considers the impact of various performance 
outcomes on incentive levels when determining quantum. These 
can be seen in the charts on page 130.

Simplicity

Proportionality

The Policy consists of three main elements: fixed pay (salary, 
benefits and pension), an annual bonus and a long-term incentive 
award. The metrics used in our incentive plans directly link back 
to our key corporate objectives and provide a clear link to the 
shareholder experience. The committee may change measures for 
future years to ensure they continue to be aligned with our strategy

A substantial portion of the package comprises of performance-
based reward, which is linked to our strategic priorities and 
underpinned by a robust target-setting process. This year, we have 
also been particularly mindful of the alignment with our workforce 
when considering the right and proportional approach to pay.

Risk

Alignment to culture

Remuneration policies are in line with our risk appetite. A robust 
malus and clawback policy is in place, and the committee has the 
discretion to reduce pay outcomes where these are not considered 
to represent overall company performance or the shareholder 
experience. Furthermore, our bonus deferral, post-cessation 
shareholding requirement, and PSP holding period ensure 
that Executive Directors are motivated to deliver sustainable 
performance.

When developing the Policy, the committee reviewed our 
approach to remuneration throughout the organisation to 
ensure that arrangements are appropriate in the context of the 
wider workforce. The themes considered include workforce 
demographics, engagement levels and diversity to ensure that 
executive remuneration is appropriate from a cultural perspective.

Remuneration Policy main changes
A number of changes were made to the Policy in 2021, bringing it in line with 
the UK Corporate Governance Code and the wider business environment. 
The 2021 Policy introduced a number of best practice governance features, 
some of which were already in operation, as summarised below: 

We also took the opportunity to refresh the performance metrics in our 
PSP. The 2021 Policy was approved by 90.2% of shareholders. 

In the context of evolving market practice since the approval of Keller’s 2021 
Remuneration Policy, the committee has reviewed its policy and proposes 
the following changes:

• 

Introduction of a two-year post-employment shareholding 
requirement for Executive Directors.

•  Discretion for the committee to override formulaic outcomes in the 

Performance Share Plan (PSP).

•  Malus and Clawback Policy.
•  Mitigation measures for Executive Director leavers written into current 

service contracts.

•  Settlement of deferred bonus and dividend equivalents in shares and 

not cash.

•  Alignment of Executive Director pensions to the general workforce.

• 

• 

• 

Increasing the maximum opportunity available under the PSP from 
150% to 200% of salary. The committee believes this increase is 
appropriate in the context of market practice and competitiveness and 
to ensure the Policy remains fit for purpose over the next three years. 
In 2023, the CEO received an LTIP award of 150% of base salary and the 
CFO received an LTIP award of 125% of base salary. The committee will 
not increase the quantum of award in 2024.
Introducing an additional trigger of ‘corporate failure’ under Keller’s 
malus and clawback policy, for good governance and in line with 
emerging market practice.

Remuneration Policy report continued

Remuneration principles
Our remuneration principles underpinning Directors’ remuneration and our Policy are:

•  Support the delivery of Keller’s strategy.
•  Align Executive Directors’ interests with those of our shareholders.
•  Attract, retain and motivate high-calibre executives to lead and manage the business and ensure the long-term sustainable success of the company.
•  Consider fairness and equity across the entirety of our workforce.

Directors’ Remuneration Policy table
There are five main elements of the remuneration package for Executive Directors: base salary, benefits, pension, performance-related annual bonus, and 
Performance Share Plan. The table below summarises these elements, how they link to strategy and discourage excessive risk-taking and their operation 
and performance measures. The Group aims to balance the need to attract, retain and motivate Executive Directors and other senior executives of an 
appropriate calibre with the need to be cost effective, whilst at the same time rewarding exceptional performance. The Policy is designed to balance these 
factors, taking account of prevailing best practice, investor expectations and the level of remuneration and pay made generally to employees of the Group.

Fixed remuneration – base salary, benefits and pension

Base salary

Purpose and  
link to strategy

Operation

Reflects the individual’s role, experience and contribution to the company.

Set at sufficiently competitive levels to attract and retain high-calibre individuals needed to execute and  
deliver on the Group’s strategic objectives.

Salaries are normally set in the home currency of the 
Executive Director and reviewed annually. Any salary 
increases are normally effective from 1 January.

In making salary decisions the committee takes 
account of:

•  changes in the scope or responsibility of the role;
•  company and individual performance;
•  periodically, salary levels for comparable roles at 

relevant international comparators; and

•  general increases across the Group.

Performance

None

Determined having considered market practice for 
relevant roles in companies of a similar size and 
complexity.

Whilst there is no prescribed maximum level of salary, 
increases are typically not expected to exceed average 
increases for the wider workforce taking into account 
relevant geography.

Larger increases could be awarded in circumstances 
where there is a significant increase in the complexity, 
scope or responsibility of the role, an increase in the 
size and complexity of the company, or in the case of 
appointment at a level lower than a predecessor and/
or typical market level with a view to increase over 
time as the Executive Director gains experience.

Opportunity

Benefits

Purpose and  
link to strategy

To be market competitive for the purpose of attracting and retaining high-calibre  
individuals needed to execute and deliver the strategic objectives.

Operation

Benefits typically include:

•  a company car or a car allowance;

Fixed remuneration – base salary, benefits and pension continued

Pension

Purpose and  
link to strategy

Operation

To provide a market-competitive level of retirement benefit.

Executive Directors participate in the company pension schemes that apply in their home country. Current UK 
Directors can elect to receive either a contribution to a UK defined contribution (DC) scheme or a salary cash 
supplement in lieu of pension benefits.

Performance

None

Opportunity

The maximum annual pension contribution/cash supplement is currently 7% of base salary unless the 
contribution rates are determined by the rules of a specific country pension plan. The level of contribution for 
Executive Directors will remain in line with the level of pension contribution received by the general workforce. 

Short-term variable remuneration

Annual Bonus Plan

Purpose and  
link to strategy

Operation

Performance

Rewards achievement of the short-term financial and strategic targets of the company.

At the start of each financial year, performance 
measures and weightings are determined and annual 
financial targets and personal strategic objectives are 
set by the committee. Bonus outcomes are 
determined based on performance against those 
targets.

The company’s malus and clawback policy may 
operate in respect of the Annual Bonus Plan (including 
deferred bonuses). The policy could take effect in the 
event of corporate failure, financial misstatement, 
serious reputational damage, or material misconduct 
in individual cases.

25% of any bonus earned is normally deferred into 
company shares for two years.

Deferred bonus shares are eligible for dividend 
equivalents over the period from the date the deferred 
award is granted, to the date of its vesting.

Dividend equivalents are settled in shares.

The annual bonus is predominantly based on delivering 
financial performance (majority weighting). This may 
include, for example, financial measures such as profit 
before tax (PBT) and working capital management. The 
remainder of the bonus is based on personal strategic 
objectives (minority weighting) which are linked to 
Keller’s strategy and assessed by the committee.

The committee agrees targets annually for threshold, 
target and maximum payouts, ensuring targets are 
achievable but stretching. No more than 50% of 
maximum is payable for target performance. Payouts 
between threshold and target, and target and 
maximum, are normally determined on a straight-line 
basis.

The committee may apply judgement and shall have 
discretion to make appropriate adjustments to an 
individual’s annual bonus payout (including, if 
appropriate, reduction to nil) or to recover the 
relevant value.

Clawback will apply to the cash bonus and deferred 
bonus for a period of two years following the end of 
the performance period.

The measures are reviewed by the committee each 
year and will be explained in the Annual report on 
remuneration.

The committee retains full discretion to adjust the 
performance measures/targets/weightings on an 
annual basis for future years to reflect the prevailing 
strategic objectives of the business.

The committee also has discretion to adjust the 
bonus outcomes (cash bonus and deferred bonus) if it 
determines this is needed to achieve an appropriate 
outcome having considered the broader performance 
of the company and/or the individual. This could, for 
example, take into account factors such as a material 
deterioration in safety performance, events 
impacting the reputation of the company, or failure to 
achieve a minimum level of financial performance 
impacting the scope for payout under personal 
strategic objectives.

Opportunity

The maximum annual bonus potential for Executive Directors is up to 150% of base salary.

Long-term variable remuneration

Performance Share Plan (PSP) 

Purpose and  
link to strategy

Focuses on delivering value creation for shareholders and sustainable financial performance for the company 
over the long term.

Operation

Performance

Typically subject to a performance period of at least 
three years with a subsequent two-year holding period, 
making it a five-year plan.

Awards are normally granted every year.

Award levels are determined annually by the committee 
and set within the policy maximum. Subject to 
stretching performance conditions.

The performance measures and targets are 
determined at the start of each performance period  
in line with the company’s financial and strategic 
objectives.

Dividend equivalents may accrue over the five-year 
period.

The performance measures and targets are 
determined at the start of each performance period in 
line with the company’s financial and strategic 
objectives.

Vesting of PSP awards is subject to performance 
against relevant financial and/or non-financial 
performance measures as determined by the 
committee.

Opportunity

The maximum award limit in each financial year is 200% 
of base salary. Individual award levels may vary and will 
be set out in the relevant Annual remuneration report.

For 2024, the CEO will receive an award of 150% of base 
salary and the CFO will receive an award of 125% of base 
salary.

The company’s malus and clawback policy may 
operate in respect of the PSP (including deferred 
bonuses). The policy could take effect in the event of 
financial misstatement, serious reputational damage, 
or material misconduct in individual cases.

The committee may apply judgement and shall have 
discretion to make appropriate adjustments to an 
individual’s annual bonus payout (including, if 
appropriate, reduction to nil) or to recover the 
relevant value.

Clawback will apply to the PSP for a period of two 
years following the end of the performance period.

For 2024, the PSP awards are based on:

•  earnings per share (EPS) with a weighting of 25%;
total shareholder return (TSR) with a weighting of 
• 
25%;
return on capital employed (ROCE) with a weighting 
of 25%; and

• 

•  operating margin with a weighting of 25%.

The committee may amend performance measures 
and weightings to reflect the prevailing strategic 
objectives of the company. The committee will 
engage with investors, to the extent it considers 
necessary, if any significant changes are made to the 
performance measures.

For threshold performance, typically 25% of the 
award will vest. For maximum performance, 100% will 
vest. Vesting will normally operate on a straight-line 
basis.

Shareholding guidelines
Purpose: aligns interests of Executive Directors with those of shareholders.

Executive Directors are expected to retain 50% net of tax of shares following the vesting of share awards until the guideline is attained. The committee 
encourages the Directors to buy shares on the market.

Minimum shareholding guideline for Executive Directors is 200% of (pre-tax) base salary.

Post-employment shareholding requirement
Executive Directors are required to hold their shares in the company for a period of two years after they have ceased to be employed by the company with 
100% of the in-employment shareholding guideline of 2 times salary (or actual shareholding if lower) to be held in year 1 and at least 50% in year 2.

Notes to the Policy table:

Annual Bonus and Deferred Bonus Plans
•  Profit-related measures are chosen by the committee as they support the strategic objectives of driving value by focusing on, and investing in, our 

key markets and the sustainability of operating profits and enhanced margins, whilst maintaining a robust balance sheet; personal strategic objectives 
allow Executive Directors to focus on strategic initiatives which support delivery of the annual business plan in any relevant year as well as laying 
foundations for delivery of the longer-term Group strategy.

•  To reinforce alignment with shareholder interests, 25% of any bonus will be deferred into the Deferred Bonus Plan (DBP). There are no further 

performance conditions applicable to the deferred bonus and it is released in the form of shares after a deferral period of two years along with any 
dividend shares accrued over the deferral period.

Performance Share Plan
•  The committee believes that the measures for 2024 (TSR, EPS, ROCE and operating margin) provide a balance of performance measures aligned 

with strategic delivery. The committee also has flexibility to adopt different measures if there are good reasons to do so and amend the weightings to 
support the strategic focus in any award year.

•  Relative TSR performance is measured by ranking against FTSE 250 companies (excluding investment trusts and financial services). Under a ranked 
approach, threshold vesting will be for median performance against the comparator group; maximum vesting for upper quartile performance (or 
above) against the comparator group. Vesting will be determined on a straight-line basis between these points. For relative TSR, we measure and rank 
growth based on the data points at the end of the performance period compared with those at the beginning of the period.

•  Underlying EPS is considered as an important indicator of revenue growth and profitability and is a simple and well-understood measure. Strong EPS 
provides the foundation for maintaining our progressive dividend policy. Targets are set by the committee taking into account internal forecasts of 
performance, any guidance provided to the market and market expectations, as well as historical performance.

•  ROCE is one of our key performance indicators. It is well-understood by participants and used internally to drive profitability. Targets are set taking 
into account our aspirations of ROCE improvement, as well as historical performance. ROCE remains an excellent measure of the efficiency of key 
resources and directly drives responsible working capital and capital expenditure decisions.

•  Operating margin reinforces management’s focus on the quality of earnings to ensure that value generated is sustainable and is aligned to the long-

term success of the business.

Awards under previous remuneration policies
The committee reserves the right to make any remuneration payments and/or payments for loss of office (including the exercise of any discretions available 
to it in connection with such payments) notwithstanding that they are not in line with the Policy where the terms of the payment were (i) agreed before 
the 2014 AGM (when the company’s first shareholder-approved Directors’ Remuneration Policy came into effect); (ii) before the Policy came into effect, 
provided that the terms of the payment were consistent with the shareholder-approved Directors’ Remuneration Policy in force at the time they were 
agreed; (iii) at a time when the individual to whom the payment is made was not a Director of the company and, in the opinion of the committee, the payment 
was not in consideration for the individual becoming a Director of the company.

For these purposes, ‘payments’ include the committee satisfying awards of variable remuneration and, in relation to an award over shares, the terms of the 
payment are agreed at the time the award is granted.

Any awards or remuneration-related commitments made to Directors under previous remuneration policies will continue to be honoured.

Committee’s discretion
• 

If an event occurs which causes the committee to consider that an outstanding PSP award or bonus would not achieve its original purpose without 
alteration, the committee has discretion to amend the targets, provided the new conditions are not materially less challenging than the original 
conditions. The committee also has discretion, both upwards and downwards, to override formulaic outcomes in the LTIP.

•  Such discretion could be used to adjust appropriately for the impact of material acquisitions or disposals, or for exceptional and unforeseen events 
outside the control of the management team. The application of any such discretion would have regard to the committee’s practice of ensuring the 
stability of measures and targets throughout the business cycle.

•  Awards may also be adjusted in the event of any variation of the company’s share capital or any demerger, capital distribution or other event that may 

materially impact the company’s share price.

The committee has discretion in several areas of policy as set out in this report. The committee may also exercise operational and administrative discretions 
under relevant plan rules approved by shareholders as set out in those rules. In addition, the committee has the discretion to amend the Policy with regard to 
minor or administrative matters where it would be, in the opinion of the committee, disproportionate to seek or await shareholder approval.

Pay for performance scenarios
The charts below provide an illustration of the potential future reward opportunities for the Executive Directors and the potential split between the different 
elements of remuneration under four performance scenarios: ‘Minimum’, ‘On-target’, ‘Maximum’ and ‘Maximum + share price growth’. Illustrations are 
intended to provide further information to shareholders regarding the pay for performance relationship.

Potential reward opportunities are based on Keller’s Remuneration Policy, applied from 1 January 2024, excluding the impact of any share price movement 
and dividend accrual during the performance period.

The ‘Minimum’ scenario reflects base salary, pension and benefits (ie fixed remuneration). Benefit levels are assumed to be the same as the last financial 
year. No annual bonus payable and threshold performance under PSP is not achieved. The ‘On-target’ scenario reflects fixed remuneration as above, plus 
bonus payout of 50% of maximum and PSP vesting at 50% of normal maximum award. The ‘Maximum’ scenario reflects fixed remuneration, plus full payout 
of all incentives. The ‘Maximum + share price growth’ scenario reflects fixed remuneration plus full payout of all incentives, with a 50% increase in share price 
applied to the PSP award.

Approach to recruitment remuneration
The committee’s approach to remuneration for newly appointed Directors (both internal and external) is consistent with that for existing Directors. However, 
where the company is considering an internal promotion to the Board, the committee may, at its discretion, decide that any remuneration commitment 
agreed or entered into prior to the promotion will continue to be honoured even though that commitment may not be consistent with the prevailing policy.

In determining appropriate remuneration, the committee will take into consideration all relevant factors to ensure that arrangements are in the best interests 
of both Keller and its shareholders and will seek not to pay more than is necessary for this purpose.

The table below summarises the committee’s approach on recruitment/promotion:

Component

Approach

Maximum

Base salary

Benefits

Pension

Annual bonus

The base salaries of new appointees will be determined by reference to relevant market data, experience 
and skills of the individual, internal relativities and their current base salary. Where new appointees have 
initial basic salaries set below market, phased increases may be awarded over a period of two to three 
years subject to the individual’s development in the role.

New appointees may be eligible to receive benefits in line with the Policy.

New appointees may be eligible to receive pension contributions or an equivalent cash supplement in 
lieu of pension in line with the Policy.

7% of salary

The structure described in the Policy table will apply to new appointees with the relevant maximum being 
pro-rated to reflect the proportion of employment over the year. Targets for the individual element will 
be tailored to each executive.

150% of salary

Performance  
Share Plan

New appointees may be granted awards under the PSP on the same terms as other executives, as 
described in the Policy table.

200% of salary

In addition, the committee may offer a ‘buyout’ payment where the committee considers it reasonable to do so in order to recruit a particular individual. The 
committee may offer compensation on a like-for-like basis, for any amounts of variable remuneration being forfeited on leaving a previous employer. In doing 
so, the committee will consider relevant factors such as expected values, any performance conditions attached to these awards and the likelihood of those 
conditions being met, time horizons, delivery mechanism and the terms of the forfeited remuneration.

To facilitate such compensation, the committee may also rely on exemptions, procedures or provisions contained in the Listing Rules that permit awards 
to be granted in exceptional circumstances. To ensure alignment from the outset with shareholders, malus and clawback provisions may also apply where 
appropriate and the committee may require new Directors to acquire company shares up to a pre-agreed level. Shareholders will be informed of any buyout 
arrangements at the time of appointment.

In making any decision on the remuneration of a new Director, the committee would balance shareholder expectations, current best practice and the 
circumstances of any new Director. It would strive not to pay more than is necessary to recruit the right candidate and would give details in the next 
remuneration report.

The committee may offer to pay reasonable relocation expenses for the new Executive Director in line with the policies described in this report.

Service contracts
Executive Directors’ contracts are for an indefinite term with one year’s notice. Service contracts between the company (or other companies in the Group) 
and current Executive Directors are summarised below. Executive Directors’ service contracts are available to view at the company’s registered office.

1  Michael Speakman was appointed Chief Financial Officer in August 2018, Interim Chief Executive Officer in October 2019 and Permanent Chief Executive Officer in December 2019.

Mitigation measures are written into current Executive Director service contracts and will be written into future Executive Director service contracts.

Payment for loss of office
When considering exit payments, the committee reviews all potential incentive outcomes to ensure they are fair to both shareholders and participants.

In a departure event, the committee will typically consider:

•  Whether any element of annual bonus should be paid for the financial year. Any bonus paid will be limited to the period served during the financial year 
in which the departure occurs. The default position is that a deferred bonus awarded in prior years will be preserved in full, unless the committee, in its 
discretion, chooses to apply malus or clawback.

•  Whether any awards under the PSP should be preserved either in full or in part.

The rules of the share plans set out the treatment of specific categories of leavers as set out below. In other cases where an executive leaves employment, 
the committee will consider the specific details of each case before determining whether to award good leaver status.

Good leaver status (including ill-health, injury or disability): deferred bonus share awards will vest in full. To the extent that performance conditions are met, 
PSP awards are pro-rated for service during the performance period and released at the normal vesting date.

Death, or sale of employing entity out of the Group: deferred bonus share awards vest in full on death or on sale. Performance conditions with regard to PSPs 
may be waived, awards may be pro-rated for service during the performance period and awards may be released early.

The default position is that an unvested PSP award or entitlement lapses on cessation of employment, unless the committee applies discretion to 
preserve some or all of the awards. This provides the committee with the maximum flexibility to review the facts and circumstances of each case, allowing 
differentiation between good and bad leavers and avoiding ‘payment for failure’.

For good leavers, deferred bonus awards will normally vest in full at the normal vesting date and PSP awards will normally continue until the normal vesting 
date or the end of the holding period although the committee may allow awards to vest (and be released from any holding period) as soon as practicable 
after leaving where appropriate. The award will vest taking into account the extent to which performance conditions have been satisfied and, unless the 
committee determines otherwise, the period of service during the performance period.

The committee maintains a discretionary approach to the treatment of leavers, on the basis that the facts and circumstances of each case are unique. 
In an exit situation, the committee will consider: the individual circumstances; any mitigating factors that might be relevant; the appropriate statutory and 
contractual position; the position under the relevant plan documentation; and the requirements of the business for speed of change.

The committee reserves the right to make any other payments in connection with a Director’s cessation of office or employment where the payments are 
made in good faith in discharge of an existing legal obligation (or by way of damages for breach of such an obligation) or by way of settlement of any claim 
arising in connection with the cessation of a Director’s office or employment or for any fees for outplacement assistance and/or the Director’s legal and/or 
professional advice fees in connection with his cessation of office or employment.

In certain circumstances, the committee may approve new contractual arrangements with departing Executive Directors including (but not limited to) 
settlement or consultancy arrangements. These will be used sparingly and are only entered into where the committee believes that it is in the best interests 
of the company and its shareholders to do so.

Change of control
In the event of a change of control, the committee will determine the extent to which unvested awards will vest after taking into account all relevant factors at 
the time including the extent to which any performance conditions have been achieved and the period of time that has elapsed from the award date to the 
date of the relevant event.

REM

Remuneration Policy report continued

External appointments
The Board may allow Executive Directors to accept external appointments and retain the fees; however, in accordance with the Code, the Board will not 
agree to a full-time executive taking on more than one Non-executive Directorship, or the chairmanship of any company. None of the Executive Directors 
held external appointments during 2023.

Remuneration policy for other employees
Keller’s approach to remuneration is broadly consistent across the Group. Consideration is given to the experience, performance and responsibilities of 
individuals. Senior managers are eligible to participate in the annual bonus scheme with similar performance measures to those used for the Executive 
Directors. Maximum opportunities vary by seniority, with business-specific measures applied where appropriate.

Members of the Executive Committee are also eligible to participate in the PSP with the same performance conditions as Executive Directors. Senior 
managers (approximately 60) are eligible to participate in the LTIP and receive shares conditional on continued employment with the company for two years. 
The award sizes vary according to seniority. Pensions and benefits provision follows local country practice.

Considerations of conditions elsewhere in the Group
When reviewing and setting executive remuneration, the committee takes into account the relevant pay and employment conditions elsewhere in the 
Group. Specifically, the level of salary increases across the Group are reviewed annually. In addition, the designated Non-executive Director with responsibility 
for workforce engagement at Keller, is a member of the committee and invited to contribute to discussions in this regard.

All senior managers are set annual objectives at the beginning of each year which support the execution of our strategic levers through delivering specific 
objectives relevant to their business unit. Annual bonuses payable to senior managers across the Group depend on the satisfactory completion of these 
objectives as well as performance against local business unit financial targets.

It should be noted that the workforce employed across the Group’s geographically diverse businesses is not a homogeneous group and pay and conditions 
are designed to be competitive in, and appropriate to, the local employment market.

Non-executive Director remuneration
The remuneration of the Non-executive Directors is determined by the Board annually within the limits set out in the Articles of Association. When setting 
the fee levels consideration is given to market practice for companies of similar size and complexity. The Chairman receives an all-inclusive fee. Non-
executive Directors receive a basic fee and additional fees may be payable for chairing a committee or performing the role of Senior Independent Director. 
The Non-executive Directors’ fees are non-pensionable and Non-executive Directors are not eligible to participate in any incentive plans.

The Chairman and Non-executive Directors will be reimbursed by the company for all reasonable expenses incurred in performing their duties. This may 
include costs associated with travel where required and any tax liabilities payable.

All Non-executive Directors have specific terms of engagement, the dates of which are set out below. All appointments are for an initial three-year period, 
and thereafter are subject to review by the Nomination and Governance Committee, unless terminated by either party on three months’ notice.

There are no provisions for compensation payable in the event of early termination.

Fees for a new Non-executive Director will be set according the principles set out above.

Fees paid to Non-executive Directors with effect from 1 January 2024 are set out in the table below.

Pension benefits represent cash in lieu of pension for Michael Speakman. David Burke’s pension contribution is paid into a private SIPP.

 The annual bonus represents the value of the bonus receivable in respect of the Group’s annual bonus plan for the relevant financial year. 25% of the bonus shown above will be deferred into Keller 
shares for a period of two years.

 For the PSP, the value shown for 2023 reflects the final vesting outcome of the 2021 PSP award with performance measured over the three-year performance period 1 January 2021 to 31 December 
2023. The final vesting outcome of the 2021 PSP award was 95.6% of maximum. The value of the award was calculated using a three-month average closing share price to 31 December 2023 of 
786p. See page 136 for further details. The 2021 award will vest on 18 March 2024. Using the average closing share price to 31 December 2023, the price appreciated from the date of the award. 

Total pension entitlements (audited)
Michael Speakman and David Burke’s pension rate has been set at 7% of base salary in line with the contribution rate provided to the majority of the UK 
workforce. The committee keeps the pension entitlement of the Executive Directors under review in the context of any changes in pension provision across 
the Group.

2023 annual bonus

Annual remuneration report continued

Corporate objectives
Corporate objectives are measurable deliverables that are jointly shared by the Executive Directors and the Executive Committee and are focused on 
supporting the delivery of Keller’s key strategic activities. The committee determined that this was an appropriate basis to incentivise management to 
increase collaboration on strategic activities. The categories of the corporate objectives have maximums from 5% to 10% of base salary that can be 
attained, with an overall maximum of 30% of base salary available (20% weighting of total annual bonus plan for Executive Directors). The committee retains 
the right to apply discretion to the overall evaluation of the attainment of corporate objectives.

The objective scoring by the committee for performance in 2023 against corporate objectives resulted in an outcome of 8.6% of salary.

As described in the Chair’s letter, the committee considered all relevant factors when determining the level of bonus payout and concluded that the annual 
bonus payments for 2023 reflects the very strong operational and financial performance of the Group. The committee’s view was that the outcome was fair 
and appropriate from both a performance perspective and also taking into account the wider stakeholder experience.

The committee carefully considered the vesting levels of the 2021 award, with additional reference to both the shareholder and wider workforce experience. 
It also specifically considered share price movements and was satisfied that there had been no inappropriate windfall gains over the period. The committee 
determined that the LTIP outcome fairly and appropriately reflected performance over the three years and no discretion was exercised.

In line with the Policy, the committee has the ability to exercise malus and clawback with regard to incentive awards in certain circumstances as outlined in the 
Policy. Overall, the committee considers that the Policy has operated as it was intended during 2023.

 For awards granted in 2020, performance conditions are measured 25% on TSR outperformance of the FTSE 250 excluding investment trusts and financial services, 50% on EPS over three years of 
the performance period, and 25% on ROCE. Awards granted in 2021 are measured 25% on TSR outperformance of the FTSE 250 excluding investment trusts and financial services, 25% on EPS over 
three years of the performance period, 25% on ROCE, and 25% on operating margin in year three. Each performance period ends on 31 December of the third year.

Includes dividend equivalents added as shares since the date of grant.

 The committee decided to make an additional PSP award to Michael Speakman to reflect his service as CEO from 1 September to 31 December 2019. This award carries the same performance 
measures as the 2019–21 PSP award and will vest in three years from the date of grant. The award was made at the same time as the 2020 PSP awards in March 2020, albeit the committee considers 
it to be remuneration awarded in respect of 2019 and supplements his 2019 PSP award.

CEO pay for performance comparison with TSR performance
The graph below shows the company’s performance, measured by TSR, compared with the performance of the FTSE 250 Index (excluding investment 
trusts and financial services) and the FTSE All-Share Index. These indices have been selected for consistency with the comparator groups used to measure 
TSR performance for PSP awards.

This graph shows the growth in value of a hypothetical £100 holding in Keller Group plc ordinary shares over 10 years, relative to a hypothetical £100 holding

The employees used for the purposes of the table above were identified as based in the UK and on a full-time equivalent basis as at 31 December 2023.

Option A was chosen as it is considered to be the most accurate way of identifying the relevant employees required by The Companies (Miscellaneous 
Reporting) Regulations 2018.

The CEO pay ratio has been calculated to show the remuneration of the CEO Michael Speakman, who has been CEO on a permanent basis for the full 
financial year.

Due to the timing of bonus payouts for the 2023 performance year, we have used the bonus payout for 2023 for the CEO and the bonus payouts for the 
comparison population that was paid in 2023, in respect of the 2022 performance year. We will update these figures with the actual amounts paid in 2022, 
in respect of the 2023 performance year, in next year’s Annual remuneration report.

 The substantial increase in all measures for David Burke between 2020 and 2021 reflects a full year of employment following his start date on 12 October 2020. In both 2020 and 2021 the financial 
targets relating to profitability and cash-based performance were achieved in full. The Executive Directors and the comparator group of employees are incentivised on the same financial metrics.

2  The increases for Non-executive Directors reflect the changes made during 2022 and 2023. 

3  Annette Kelleher was appointed in December 2023.

Paul Withers and Nancy Tuor Moore retired in June 2020 and May 2022 respectively.

 The comparator group comprises the population of Keller UK and group head office employees being professional/managerial employees based in the UK and employed on more readily comparable terms.

 The change in components of the comparator group remuneration is on a per capita basis, the year-on-year increases, reflect large percentage increases in small value benefits such as travel allowances.

2  Total remuneration reflects overall employee costs. See note 8 to the consolidated financial statements for further information.

Summary of implementation of the Remuneration Policy during 2023 and 2024
Overall, the committee considers that the Remuneration Policy has operated as it intended during 2023, with no deviations. A summary of how the 
committee intends the Policy to be operated during 2024 can be found in the remuneration policy report on pages 126 to 134.

2024 base salary and benefits
The committee noted that salary increases for UK-based employees across the Group were generally around 6.5%, effective 1 January 2024. The Executive 
Directors received salary increases of 4.5% for 2024.

Benefits for 2024 will remain broadly unchanged from prior years.

2024 pensions
Pension contributions for Michael Speakman and David Burke have been set at 7% of base salary in line with the rate provided to the majority of the 
workforce in the UK and on a weighted average basis around Keller’s most populous locations.

2024 annual bonus
For 2024, 70% of Executive Directors’ bonus will be based on Group financial results and 30% will be based on shared corporate objectives. The performance 
measures will be underlying operating profit, an important indicator of the company’s financial and operating performance, and a cash-based target, a more 
operational measure. Targets for each measure are challenging but realistic and have been set in the context of the business plan. Targets will be disclosed 
retrospectively in the 2023 Annual remuneration report to the extent that they are no longer considered commercially sensitive.

25% of any bonus earned will be deferred into company shares for two years.

2024–26 Performance Share Plan Awards (PSP)
The 2024–26 PSP performance conditions will be assessed over three years based on the following measures: relative TSR (25% weight), cumulative EPS 
(25% weight), return on capital employed (ROCE) (25% weight) and operating profit margin (25% weight). These measures strongly align potential payout 
under the PSP with Keller’s strategic priorities.

Relative TSR performance will be measured by ranking against FTSE 250 companies (excluding investment trusts and financial services). Under a ranked 
approach, a threshold vesting (resulting in 25% of that portion of the award vesting) will be for median performance against the comparator group; 
maximum vesting for upper quartile performance (or above) against the comparator group. Straight-line vesting between these points.

EPS will be measured on a cumulative basis enabling target setting to reflect business plans, market consensus and the position in the construction cycle.

Cumulative EPS of 500p over the three-year period will enable full vesting of this performance condition, with a threshold vesting of 25% if 400p is achieved, 
calculated off the 2021 underlying EPS (at IFRS 16 basis) of 88.4p.

ROCE will be measured on an average basis over the three-year performance period, with a threshold level of performance of 20% (leading to 25% of that 
portion of the award vesting) and a maximum of 25%. Straight-line vesting between these points.

Operating profit margin will be measured in year three (with a threshold vesting of 6.0% leading to 25% of that portion of the award vesting) and maximum of 
7.0%. Straight-line vesting between these points.

These targets have been carefully assessed and the committee considers them to be appropriately stretching, given the company’s business plans, 
opportunity set and investor expectations and the challenging macroeconomic environment.

2024–26 Performance Share Awards
To reflect the impact of any changes in IFRS accounting standards, the committee will consider adjusting financial targets for all subsisting PSP awards, 
ensuring that they are not materially easier or harder to satisfy than the original targets. Any amended targets determined by the committee will be 
disclosed to shareholders in the next Directors’ remuneration report.

Consideration by the Directors of matters relating to Directors’ remuneration
The following Directors were members of the Remuneration Committee when matters relating to the Directors’ remuneration for 2024 were being considered:

•  Eva Lindqvist
•  Juan G. Hernández Abrams
•  Paula Bell
•  Baroness Kate Rock
•  Annette Kelleher

During the year, the committee received assistance from Kerry Porritt (Group Company Secretary and Legal Advisor) on salary increases, bonus awards, 
share plan awards and vesting, and policy and governance matters. David Burke (Chief Financial Officer) presented information with regard to 2023 
financial performance and 2024 budget and the three-year plan for 2024–26. In determining the Executive Directors’ remuneration for 2023 and 2024, the 
committee consulted the Chairman and the CEO about its proposals, except (in the case of the CEO) in relation to their own remuneration. No Director was 
involved in determining their own remuneration.

No member of the committee has any personal financial interest (other than as a shareholder), conflict of interest arising from cross-directorships or day-
to-day involvement in running the business. Given their diverse backgrounds, the Board believes that the members of the committee are able to offer an 
informed and balanced view on executive remuneration issues.

Corporate governance
The committee’s terms of reference, which were reviewed during the year, are available on the Group’s website (www.keller.com) and on request from the 
Group Company Secretary and Legal Advisor.

The committee conducted an effectiveness review of the business covered during the year against its terms of reference. 

External advisers
During the year, the committee received advice from Deloitte, an independent firm of remuneration consultants appointed by the committee after 
consultation with the Board. The committee is satisfied that Deloitte is and remains independent of the company and that the advice provided is impartial 
and objective. Deloitte is a founding member and signatory of the Code of Conduct for Remuneration Consultants, details of which can be found at  
www.remunerationconsultantsgroup.com.

During the year, Deloitte also provided advice in relation to tax compliance and risk advisory services. The committee is satisfied that the provision of these 
services did not impair Deloitte’s ability to advise the committee independently and objectively. Their total fees for the provision of remuneration services to 
the committee for 2023 were £43,250.

Kerry Porritt
Group Company Secretary and Legal Advisor

4 March 2024

Registered office: 
2 Kingdom Street 
London W2 6BD

Registered in England No. 2442580

Company law requires the Directors to prepare Group and company 
financial statements for each financial year. Under that law they have 
elected to prepare the Group financial statements in accordance with 
UK-adopted International Accounting Standards in conformity with the 
requirements of the Companies Act 2006, and the parent company 
financial statements in accordance with UK Accounting Standards, 
including FRS 101 Reduced Disclosure Framework. 

Under company law the Directors must not approve the financial 
statements unless they are satisfied that they give a true and fair view of the 
state of affairs of the Group and company and of their profit or loss for that 
period. In preparing each of the Group and company financial statements, 
the Directors are required to:

•  select suitable accounting policies and then apply them consistently;
•  make judgements and estimates that are reasonable and prudent;
for the Group financial statements, state whether they have been 
• 
prepared in accordance with UK-adopted International Accounting 
Standards in conformity with the requirements of the Companies 
Act 2006;
for the company financial statements, state whether the applicable 
UK Accounting Standards have been followed, subject to any 
material departures disclosed and explained in the company financial 
statements;

• 

•  assess the Group and company’s ability to continue as a going 

concern, disclosing, as applicable, matters relating to going concern; 
and

•  use the going concern basis of accounting unless they either intend to 
liquidate the Group or the company or to cease operations, or have no 
realistic alternative but to do so.

The Directors are responsible for keeping adequate accounting records that 
are sufficient to show and explain the company’s transactions and disclose 
with reasonable accuracy at any time the financial position of the company 
and enable them to ensure that its financial statements comply with the 
Companies Act 2006. They are responsible for such internal control as they 
determine is necessary to enable the preparation of financial statements 
that are free from material misstatement, whether due to fraud or error, and 
have general responsibility for taking such steps as are reasonably open to 
them to safeguard the assets of the Group and to prevent and detect fraud 
and other irregularities.

Under applicable law and regulations, the Directors are also responsible for 
preparing a Strategic report, a Directors’ report, a Directors’ remuneration 
report and a Corporate governance statement that comply with that law 
and those regulations.

The Directors are responsible for the maintenance and integrity of the 
corporate and financial information included on the company’s website. 
Legislation in the UK governing the preparation and dissemination of 
financial statements may differ from legislation in other jurisdictions.

standards are further described in the Auditor’s responsibilities for the audit of the financial statements section of our report. We believe that the audit 
evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Independence
We are independent of the Group and parent company in accordance with the ethical requirements that are relevant to our audit of the financial statements 
in the UK, including the FRC’s Ethical Standard as applied to listed public interest entities, and we have fulfilled our other ethical responsibilities in accordance 
with these requirements.

Conclusions relating to going concern 
In auditing the financial statements, we have concluded that the Directors’ 
use of the going concern basis of accounting in the preparation of the 
financial statements is appropriate. Our evaluation of the Directors’ 
assessment of the Group and parent company’s ability to continue to adopt 
the going concern basis of accounting included:

• 

In conjunction with our walkthrough of the Group’s financial 
statements close process, we confirmed our understanding of 
management’s going concern assessment process and also engaged 
with management early to ensure key factors were considered in 
their assessment, including the evaluation of the current economic 
environment impacting the Group and our own independent 
assessment of risk. This included macroeconomic factors such as 
uncertainty over future interest rates, the price of steel, and continued 
inflationary pressure over the cost of material, energy and labour. 
•  We obtained management’s Board-approved forecast cash flows and 
covenant calculation covering the period of assessment from the date 
of signing to 31 March 2025. As part of this assessment, the Group 
has modelled a number of adverse scenarios in their cash forecasts 
and covenant calculations in order to incorporate unexpected changes 
to the forecasted liquidity of the Group.

•  We assessed the reasonableness of the cash flow forecast through 
analysing management’s historical forecasting accuracy, challenging 
the robustness of the Group’s orderbook, and considering actual post 
year-end performance to date. We have assessed how management 
considered the future profitability and cashflows assumed in the 
base case forecast to take account of significant one-off margin 
contributions during the current year for example windfall from steel 
prices one-off items which are not expected to recur. We evaluated 
the key assumptions underpinning the Group’s assessment by 
challenging the measurement and completeness of downside 
scenarios modelled by management and how these compare with 
principal risks and uncertainties of the Group. 

•  We considered the extent to which current and emerging climate-

related risks may affect the Group’s assessment, including 
assumptions around the long-term reliance on concrete, steel and 
related manufacturing processes, the use of heavy-duty combustion 
machinery, ‘Environmental, Social and Governance’ related covenants 
or levies, the cost of climate adaptation solutions, and the exposure 
to extreme weather events which could delay project completion or 
cause damage to physical assets. We have also considered the impact 
of increased replacement cost for capex arising from stranded assets 
which do not meet the required carbon emission standards. 

•  We tested the clerical accuracy and logical integrity of the cash flow 
forecast model, used to prepare the Group’s going concern and 
viability assessments.

•  We considered whether the Group’s forecasts and related key 

assumptions in the going concern assessment were consistent 
with other forecasts used by the Group in its accounting estimates, 
including goodwill impairment and deferred tax asset recognition.
•  We evaluated, based on our own independent analysis, what reverse 
stress testing scenarios could lead either to a breach of the Group’s 
banking covenants or a liquidity shortfall and whether these scenarios 
were plausible.

•  Our analysis also considered the mitigating actions that management 
could undertake in an extreme downside scenario and whether these 
were achievable and in control of management.

•  We confirmed the continued availability of debt facilities through the 
going concern period and reviewed their underlying terms including 
the new private placement of $300m entered into during the year, 
including covenants, by examination of executed documentation, and 
agreed the amounts drawn down at year end to external confirmations 
from the banks.

•  We extended our procedures (including inquiries of management, 

considering the forward order book, and maturity of debt/availability 
of access to future financing in the viability period) to consider 
events beyond 31 March 2025, including the forecast for covenant 
compliance at the next testing interval as at 30 June 2025. We have 
also inquired with our debt advisory specialist over the availability and 
prospects of Keller’s refinancing options based on the corporate 
finance market for the sector, noting the maturity of facilities due 
to expire after the going concern period, most notably the revolving 
credit facility, due to expire in November 2025.

•  We considered whether management’s disclosures in the financial 
statements sufficiently and appropriately capture the impact of 
the Group’s principal risks and uncertainties on the going concern 
assessment and through consideration of relevant disclosure 
standards. 

•  The audit procedures performed in evaluating the Directors’ 

assessment were performed by the Group audit team, however 
we also considered the financial and non-financial information 
communicated to us from our component teams of key locations as 
sources of potential contrary indicators which may cast doubt over the 
going concern assessment.

The results from both management’s evaluation and our independent 
reverse stress testing suggest that the Group would need to be exposed 
to downside events significantly greater than the financial effect of the 
disruption caused in recent years (eg due to COVID-19 and Russia’s 
invasion of Ukraine) throughout the going concern period in order to breach 
its covenants or exhaust its available funding.

The Group has borrowing facilities available to it during the going concern 
period. The undrawn committed facilities available as at 31 December 2023 
amounted to £377.8m which comprises mainly of the Group’s £375m 
revolving credit facility, expiring on 23 November 2025.

Conclusion
Based on the work we have performed, we have not identified any material 
uncertainties relating to events or conditions that, individually or collectively, 
may cast significant doubt on the Group and parent company’s ability to 
continue as a going concern for a period through to 31 March 2025.

In relation to the Group and parent company’s reporting on how they have 
applied the UK Corporate Governance Code, we have nothing material 
to add or draw attention to in relation to the Directors’ statement in the 
financial statements about whether the Directors considered it appropriate 
to adopt the going concern basis of accounting.

Our responsibilities and the responsibilities of the Directors with respect 
to going concern are described in the relevant sections of this report. 
However, because not all future events or conditions can be predicted, 
this statement is not a guarantee as to the Group’s ability to continue as a 
going concern.

Overview of our audit approach

Audit scope

•  We performed an audit of the complete financial information of 63 components and audit procedures on 

specific balances for a further 19 components.

•  The components where we performed full or specific audit procedures accounted for 93% of profit before tax, 

94% of revenue and 95% of total assets.

Key audit matters

Improper revenue recognition.

• 
•  Carrying value of goodwill.
•  Quality of earnings including disclosure of non-underlying items.

Materiality

•  Overall Group materiality of £7.0m which represents 4.6% of profit before tax, adjusted for one-off, non-

underlying items.

An overview of the scope of the parent company  
and Group audits 

Tailoring the scope
Our assessment of audit risk, our evaluation of materiality and our allocation 
of performance materiality determine our audit scope for each company 
within the Group. Taken together, this enables us to form an opinion on 
the consolidated financial statements. We take into account size, risk 
profile, the organisation of the Group and effectiveness of Group-wide 
controls, changes in the business environment, the potential impact of 
climate change and other factors such as recent internal audit results when 
assessing the level of work to be performed at each company.

The reporting components where we performed audit procedures 
accounted for 93% (2022: 91%) of the Group’s profit before tax, 94% 
(2022: 93%) of the Group’s revenue and 95% (2022: 96%) of the Group’s 
total assets. For the current year, the full scope components contributed 
78% (2022: 48%) of the Group’s profit before tax, 64% (2022: 67%) of 
the Group’s revenue and 67% (2022: 70%) of the Group’s total assets. 
The specific scope component contributed 15% (2022: 43%) of the 
Group’s profit before tax, 30% (2022: 26%) of the Group’s revenue and 
28% (2022: 27%) of the Group’s total assets. The audit scope of these 
components may not have included testing of all significant accounts of 
the component but will have contributed to the coverage of significant 
accounts tested for the Group. 

In assessing the risk of material misstatement to the Group financial 
statements, and to ensure we had adequate quantitative coverage of 
significant accounts in the financial statements, of the 208 reporting 
components of the Group, we selected 82 components covering entities 
within AMEA, Europe and North America, which represent the principal 
business units within the Group.

Of the 82 components selected, we performed an audit of the complete 
financial information of 63 components (‘full scope components’) which 
were selected based on their size or risk characteristics. This also reflects 
inclusion of consolidation entities representing manual adjustments posted 
in topside at the Group consolidated level, which we have treated as full 
scope. For 19 components (‘specific scope components’), we performed 
audit procedures on specific accounts within that component that we 
considered had the potential for the greatest impact on the significant 
accounts in the financial statements either because of the size of these 
accounts or their risk profile.

Of the remaining 126 components that together represent 7% of the 
Group’s profit before tax, none are individually greater than 3% of the 
Group’s profit before tax. For these components, we performed other 
procedures, including analytical review and/or ‘review scope’ components, 
testing of consolidation journals and intercompany eliminations and foreign 
currency translation recalculations to respond to any potential risks of 
material misstatement to the Group financial statements.

The charts below illustrate the coverage obtained from the work performed 
by our audit teams.

Keller Group plc  Annual Report and Accounts 2023

151

Changes from the prior year 
For the current year, we evaluated the emerging increase in risk on revenue 
recognition such as with Keller Arabia, which is servicing the work related to 
the NEOM project in Saudi Arabia, where we applied specific risk-focused 
procedures on the current year, compared with other procedures in the 
prior year. The determination of our group scoping was made through our 
updated risk assessment and a reflection of the low rate of misstatements 
identified in the previous cycles, as well as the relative contribution of these 
entities to the Group as a whole. The scope for the current year continued 
to focus on the key areas of audit focus and judgement, including, but not 
limited to, revenue recognition and we increased the scope of procedures 
performed across the Group in areas of emerging increases in risk. We 
applied specific risk-focused procedures on these entities rather than 
specified procedures on certain areas in the prior year. Our scoping reflects 
the inclusion of consolidation entities representing manual adjustments 
posted topside at the Group consolidated level, which we have treated as 
full scope.

Involvement with component teams 
In establishing our overall approach to the Group audit, we determined the 
type of work that needed to be undertaken at each of the components 
by us, as the primary audit engagement team, or by component auditors 
from other EY global network firms operating under our instruction. Of 
the 63 full scope components, audit procedures were performed on 61 
of these directly by the primary audit teams. This included consolidation 
entities representing manual adjustments posted topside at the Group 
consolidated level, which we have treated as full scope. For the two 
remaining full scope and 19 specific scope components, where the work 
was performed by component auditors or centrally by the primary audit 
team, we determined the appropriate level of involvement to enable us to 
determine that sufficient audit evidence had been obtained as a basis for 
our opinion on the Group as a whole.

In addressing the appropriateness of oversight arrangements for 
component teams, the Group audit team executed an oversight strategy 
consisting of physical and virtual site visits for in-scope components, the 
latter being enabled through the use of video conferencing. The Group 
audit team (including the Senior Statutory Auditor) visited the principal 
operating business of North America during the planning/interim phase of 
the audit which involved discussing the audit approach with the component 
team and any issues arising from their work, meetings with local and 
divisional management to discuss key accounting judgements on revenue 
and provisions, conducting contract site visits, and reviewing key audit 
working papers in the high-risk areas. The virtual site visits, which occurred 
throughout the key audit periods, involved the primary team (including 
the Senior Statutory Auditor) meeting with our component teams to 
discuss and direct their audit approach, reviewing key working papers and 
understanding the significant audit findings in response to the risk areas 
including revenue recognition and areas of judgement and estimation 
such as contract liabilities and provisions for legal claims (including insured 
liabilities). We also attended virtual meetings with local management, 
obtaining updates on reported financial performance and significant risk 
areas for the audit, including the anticipated business outlook during the 
going concern period.

The primary team interacted regularly with the component teams, 
during various stages of the audit, reviewed key working papers and 
were responsible for the scope and direction of the audit process. This, 
together with the additional procedures performed at Group level, gave us 
appropriate evidence for our opinion on the Group financial statements.

Climate change 
Stakeholders are increasingly interested in how climate change will impact 
Keller Group plc. The Group has assessed the principal risks and impact 
of climate change for the business in relation to (a) its inability to deliver 
environmentally friendly and/or regulatory conforming solutions impacting 
its clients and reputation, (b) disruptions to operations and damage/
impairment to assets or installed works from physical events, such as 
storms, floods or wildfires, and (c) transition risks such as the cost of carbon 
intensive materials, and the growing necessity to monitor and report 
reduction of Scope 3 emissions.

These are explained on pages 48 to 58 in the Task Force on Climate-related 
Financial Disclosures (TCFD) and on page 43 in the principal risks and 
uncertainties. The Group has also explained its climate commitments on 
pages 63 to 67. All of these disclosures form part of the ‘Other information’, 
rather than the audited financial statements. Our procedures on these 
unaudited disclosures therefore consisted solely of considering whether 
they are materially inconsistent with the financial statements, or our 
knowledge obtained in the course of the audit or otherwise appear to be 
materially misstated, in line with our responsibilities on ‘Other information’. 

In planning and performing our audit we assessed the potential impacts of 
climate change on the Group’s business and any consequential material 
impact on its financial statements. 

The Group has explained in its basis of preparation in note 2 on how 
they have considered the impact of climate change in their financial 
statements, particularly in the context of the risks identified in the TCFD 
disclosure on pages 48 to 58 this year. The basis of preparation also explains 
management’s consideration of the impact of climate change in respect to 
(a) estimates of future cash flows used in impairment assessments of the 
carrying value of goodwill, (b) the useful economic life of plant, equipment 
and other intangible assets, and (c) going concern and viability of the Group 
over the next three years. Whilst management disclosed that there is 
currently no material short-term impact expected from climate change, 
they are aware of the variable risks arising from climate change and thus 
they will regularly assess these risks against judgement and estimates 
made in preparation of the Group’s financial statements. 

Our audit effort in considering the impact of climate change on the 
financial statements was focused on evaluating management’s 
assessment of the impact of climate risk, physical and transition, their 
climate commitments, the effects of material climate risks disclosed on 
pages 48 to 58 and the significant judgements and estimates disclosed 
in note 2. We have assessed whether the impact of climate-related risks 
has been appropriately reflected in future cash flows used to assess the 
carrying value of goodwill, economic life of plant, equipment and other 
intangible assets and the going concern and viability assessment (see 
note 2) following the requirements of UK adopted international accounting 
standards. As part of our audit testing and applying profession scepticism, 
we performed our own risk assessment, supported by our climate change 
internal specialists, to determine the risks of material misstatement in the 
financial statements from climate change which needed to be considered in 
our audit. Our audit testing included challenges to management with regard 
to cost assumptions around climate adaptation solutions, and the exposure 
to extreme weather events which could delay project completion or cause 
damage/impairment to physical assets and the assumptions for capex 
requirement in the forecasted going concern and viability period including 
goodwill. We corroborated our analysis with market available information 
for any change in climate-related regulations and discussion with our 
component team. In determining the valuations and the timing of future 
cash flows, we acknowledged that there is degree of certainty involved and 
all climate-related risks or future outcome are not yet known.

We also challenged the Directors’ considerations of climate change risks 
in their assessment of going concern, viability and associated disclosures. 
Where considerations of climate change were relevant to our assessment 
of going concern, these are described above. 

Based on our work we have not identified the impact of climate change 
on the financial statements to be a key audit matter. We considered the 
impact of climate change on the future cash flows which have been used 
to assess the carrying value of goodwill and going concern including 
the viability assessment. Details of our procedures and findings on the 
goodwill impairment assessment are included in the key audit matters 
section overleaf.

Key audit matters 
Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements of the current 
period and include the most significant assessed risks of material misstatement (whether or not due to fraud) that we identified. These matters included 
those which had the greatest effect on: the overall audit strategy, the allocation of resources in the audit and directing the efforts of the engagement 
team. These matters were addressed in the context of our audit of the financial statements as a whole, and in our opinion thereon, and we do not provide a 
separate opinion on these matters. 

Key observations communicated 
to the Audit and Risk Committee 

From the audit procedures 
performed, we conclude that 
the recognition of revenue was 
appropriate, that the 
judgements made by 
management are consistent 
with the accounting policy to be 
applied to all contracts with 
customers, and that the 
presentation and disclosure of 
revenue is materially correct.

Risk 

Our response to the risk

For all revenue recorded on the input method and output 
method bases, we:

•  Performed walkthroughs of significant classes of revenue 
transactions and assessed the design effectiveness of key 
controls.

•  Performed a risk assessment of the population of contracts 

and selected a sample of higher-risk (value and/or 
complexity) contracts across the Group, representing both 
those accounted for using the input and output methods. 
For the sample selected we obtained an understanding of 
the contract terms, key operational or commercial/financial 
issues, significant judgements that impact the contract 
position and the appropriateness of revenue recognised at 
31 December 2023. The factors that we considered when 
determining additional higher-risk contracts to select 
included low-margin, loss-making and/or contracts subject 
to delayed performance or commencement and where the 
ability to continue work had been affected by circumstances 
outside the Group’s control.

For the sample selected for testing we:

•  Considered the appropriateness of supporting evidence and 
the requirements of IFRS 15 and the Group’s accounting 
policies where contracts included additional entitlements 
to variations and claims, both for and against the Group.
•  We had meetings with the contract project managers to 
understand the project status and outstanding works 
remaining on the contracts, and to ensure that the financial 
information recorded was consistent with their input.

•  Challenged the level of unbilled revenues and the adequacy 
of the evidence to prove recoverability through subsequent 
work certifications and cash collections.

For the sample of contracts where revenue was recognised 
over time under the input method basis, we have performed 
the following:

•  Challenged the reasonableness of management’s 
calculations of costs to complete, which included 
understanding the risks and outstanding works remaining 
on the contract, the impact of any delays or other delivery 
issues and the related cost assumptions and contingencies.
•  We tested the cost build up and the correct allocation across 
contracts (e.g. to verify no manipulation of costs between 
profitable and loss-making contracts and recognition 
between periods (e.g. cut-off testing)) through a 
combination of cost verification and analytical procedures 
on contract margins.

•  Evaluated the expected margin and revenue recognised to 

date against latest contract progress.

Improper revenue recognition 
(management override of controls) (2023: 
£2,966.0m, 2022: £2,944.6m)

Refer to the Audit and Risk Committee 
report (page 112); Accounting policies (page 
164); and note 4 of the consolidated financial 
statements (page 174)

The Group recognises revenue over time 
from contracts either through the output 
method or the input method basis, 
depending on the size and nature of the 
contract (in accordance with the guidelines 
provided in the Group revenue recognition 
policy and IFRS 15). The judgements involved 
in determining revenue recognition under 
both recognition methods present a 
significant fraud risk as results are susceptible 
to manipulation, particularly around the 
estimation in determining the cost to 
complete and the percentage of completion 
achieved at the year end. Management may 
use inappropriate measures or assumptions 
to evaluate the Group’s progress towards 
complete satisfaction of a performance 
obligation, recognition of revenue relating to 
variations/change orders and claims, and/or 
inappropriately record manual, ‘topside’ 
journal entries to misstate revenues 
recognised under the output method. Under 
the input method management may use 
inappropriate assumptions and judgements 
when estimating forecast costs of contracts 
at completion and/or the projected outcome 
of additional claims made against the Group 
or in respect of estimates of the Group’s 
entitlement to variable consideration from 
customers, resulting in inaccurate 
recognition of revenue and profits.

There is also significant judgement involved 
in estimating the impact of factors such as 
rising cost pressures and the availability of 
necessary skills and their impact on the cost 
of satisfying outstanding performance 
obligations and the projected outcome of 
contract claims and variations made both by 
and against the Group and valuation of 
contract provisions for both the input and 
output method bases. 

The Group also provides fabricated, 
unbonded post-tension materials to 
customers in the residential and commercial 
sectors, as well as geotechnical monitoring 
solutions. The revenue from sales of these 
materials is recognised at a point of time, 
based upon the satisfaction of the 
performance obligations. We have identified 
that there is a risk that such revenues could 
be manipulated at or near to the period end 
through inappropriate ‘cut-off’ to meet 
income statement targets.

•  Evaluated whether the assessment of output method 
appropriately depicted outputs actually delivered and 
progress towards satisfaction of performance obligations.
•  We tested the cost build up and the correct allocation across 
contracts (e.g. to verify no manipulation of costs between 
profit-making and loss-making contracts) through a 
combination of cost verification against invoices and 
analytical procedures.

•  Tested whether revenue has been recognised in the 

appropriate period. This included checking whether revenue 
recognised at the year end on open contracts is supported 
by evidence (e.g. measured works certificates) that 
demonstrates the period in which the work was performed. 
For any loss-making contracts identified, for both input 
method and output method contracts, we tested whether 
management’s assessment of the forecast loss included 
appropriate estimates in respect of costs to completion.

For contracts where there was significant uncertainty over 
whether the project would be completed, we assessed the 
appropriateness of the accounting treatment of contract 
modifications, consideration received, and revenue 
recognised/deferred and the impact on the carrying value of 
related assets.

For revenue recognised at a point in time, we performed 
revenue cut-off procedures at the year end to determine 
whether transactions are recorded in the appropriate period 
based on the recognition criteria under IFRS 15 by vouching 
the transactions through to third-party support (such as 
shipping, delivery or acceptance documents).

Data-driven journal entry testing was also performed in full and 
specific scope locations on a risk-based approach, including 
focusing on entries which were posted manually or those which 
could be made to overstate revenue and unbilled revenue. 

We have performed enquiries of management to understand 
all provisions held and management’s assessment under the 
new amendment of IAS 37 for where provisions have been 
recognised or not for the purpose of assessing whether a 
contract is onerous and to assess the cost of fulfilling the 
contract, for example allocations of indirect or general 
overheads. All contract provisions have been discussed with 
management and project managers.

We performed full and specific scope audit procedures over 
revenue in 81 locations, which covered 94% of the risk amount.

Risk 

Our response to the risk

Carrying value of goodwill (2023: £107.6m; 
2022: £125.3m)

Refer to the Audit and Risk Committee 
report (page 112); Accounting policies (page 
164); and note 15 of the consolidated 
financial statements (pages 184–185)

Under IAS 36, an entity must assess 
intangible items with an indefinite useful 
life annually, or whenever indicators of 
impairment are present for all other assets. 

Due to the degree of estimation involved in 
calculating the expected future cash flows 
from cash-generating units (CGUs) and 
determining appropriate long-term growth 
rates and discount rates specific to each 
CGU (including those arising from 
acquisitions), we have identified a significant 
risk regarding the assessment of any 
impairment against goodwill carrying values, 
as well as the identification of any indicators 
of impairment as an area of significant risk.

We have performed the following:

•  Performed a walkthrough to understand the impairment 

analysis and calculation process (e.g. controls over the data 
and assumptions used), level of review on the outlook data in 
future years and how key inputs were derived.

• 

•  Evaluated the appropriateness of the CGUs identified given 
changes in Group structure (including acquisitions) and the 
allocation of assets and liabilities to the CGUs.
In respect of each CGU, we have challenged management 
over the key inputs and on the achievability of the cash flow 
forecasts. We have assessed the projected financial 
information against recent performance and other market 
data to assess the robustness of management’s forecasting 
process.

•  Assessed the discount rates applied against cash flows for 
each CGU by obtaining the underlying data used in the 
calculation and benchmarking against comparable 
organisations with the support of our EY valuation experts.
•  Validated the revenue/margin growth rates assumed for the 
projected financial information for each CGU by comparing 
them to economic and industry forecasts.

•  Given the uncertainty attached to forecasts presented by 

rising costs, skills shortages and the potential for 
suspension or delay to key projects, we have assessed 
management’s assumptions in relation to these factors 
including the ongoing market uncertainties and increasing 
costs of materials and labour, in determining the ability to 
achieve cash flow forecasts.

•  Analysed the historical accuracy of budgets compared with 
actual results to determine whether forecast cash flows are 
reliable based on past experience. 

•  Challenged the assumptions in the approach taken to 

determine working capital levels over the forecast period, 
focusing on the principal reasons and timing of larger 
fluctuations and how this compared with the historical trend.

•  Performed an integrity review of the goodwill model to be 
able to conclude that the formulae and construction of 
these models are effective and accurate.

•  Performed sensitivity analyses by testing key assumptions 
in the model to recalculate a range of potential outcomes in 
relation to the size of the headroom between carrying value 
and fair value.

•  Considered the assumptions around the long-term reliance 
on concrete, steel and related manufacturing processes, 
heavy-duty combustion machinery, and the potential for 
‘Environmental, Social and Governance’ related covenants 
or levies which could impact the CGU cash flows. We have 
also considered the assumptions made by management 
around the cost of investment in technology and capex in 
order to adapt to changing regulations related to climate 
change and emissions.

•  Considered the appropriateness of the related disclosures 
provided in the notes to the Group financial statements. 

The primary team centrally executed the work performed 
across all locations, covering 100% of the balance. Component 
teams have supported the primary team in assessing the 
growth rates and achievability of the cash flows based on their 
understanding of the business and local market and industry 
conditions.

Key observations communicated 
to the Audit and Risk Committee 

Our procedures focused on the 
CGUs where the headroom was 
either lower and/or sensitive to 
changes in key assumptions, 
including improved future 
performance. Through our 
process of challenging 
management and 
understanding their 
assumptions, we concur with 
their conclusion that the 
goodwill recorded in Keller 
Limited (£12.1m), is impaired.

Keller Norway and Keller 
Canada were classified as 
high-risk CGUs as part of our 
risk assessment. We assessed 
Keller Canada to be highly 
sensitive to changes in cash 
flows and the forecasts were 
underpinned by future 
successful execution of 
business plans designed to 
address the current year poor 
performance in margins and 
profitability. Management has a 
business plan to turn around 
the current year poor 
performance for the Canada 
CGU and the Norway CGU has 
been restructured in 2023. We 
have challenged 
management’s plan and 
assessed the sensitivity of 
those plans to the forecasts. 
We have ensured that 
adequate disclosures have 
been made in the annual report 
to disclose the key sensitivities, 
assumptions and available 
headroom for the Canada CGU.

For the remaining CGUs, there 
is sufficient headroom to 
support the carrying value.

We concluded that 
management have accounted 
for the impairments calculated 
appropriately and have included 
sufficient disclosure over the 
key assumptions and

Key observations communicated 
to the Audit and Risk Committee 

As a result of our audit 
procedures performed, no 
items were inappropriately 
included or excluded from 
non-underlying items.

We have assessed that the 
alternative performance 
measures (APMs) included in 
the Group financial statements 
are appropriately defined, 
reconciled to GAAP measures 
and disclosed. 

Risk 

Our response to the risk

Quality of earnings, including disclosure of 
non-underlying items (2023: £27.9m 
(pre-tax); 2022: £37.2m (pre-tax))

Refer to the Audit and Risk Committee 
report (page 112); Accounting policies (page 
164); and note 9 of the consolidated financial 
statements (page 177)

The Group’s accounting policy is to classify 
certain income statement items as 
non-underlying, where they are exceptional 
by their size and/or are non-trading in 
nature, including amortisation of acquired 
intangibles and other non-trading amounts, 
including those relating to acquisitions and 
disposals. 

As at the year end, management identified 
certain pre-tax items totalling £27.9m which 
they believe are significant by either size 
and/or nature, which warrant separate 
disclosure in the consolidated financial 
statements to better reflect underlying 
business performance.

The classification of such items is 
judgemental and there is a risk that material 
items are misclassified as ‘non-underlying’ 
and are therefore excluded from the results 
presented in the form of adjusted profit 
measures, which would mislead the users of 
the financial statements in understanding 
the performance of the Group.

Furthermore, there is a risk that the financial 
statements give undue prominence to 
adjusted performance measures compared 
with their IFRS equivalents.

We performed the following procedures: 

•  Obtained the breakdown of non-underlying items to 

determine whether by their nature they meet the definition 
of non-underlying items, in accordance with Group policy 
and ESMA (European Securities and Markets Authority) 
guidelines on Alternative Performance Measures. 

•  Tested that the amounts included as non-underlying items 

are supported by appropriate evidence. We performed tests 
of detail over costs classified as ERP costs and assessed 
whether this is consistent with what other companies are 
disclosing in the sector, the interpretation of the latest IFRIC 
for cloud computing costs, and the Group’s policy for 
non-underlying items. We also performed tests of detail 
over material restructuring costs to ensure that the 
underlying expenditure recorded truly relates to a specified 
restructuring project and not a general or recurring expense, 
and that the IAS 37 criteria have been correctly met. We 
were assisted by our component teams in locations where 
these material expenditures have arisen. 

•  Assessed the appropriateness of the disclosures of 
non-underlying items in light of IFRS (IAS 1) and the 
continued focus by the accounting regulators on alternative 
performance measures (APMs) with the support of our EY 
technical review team, we focused on:

 – the clarity of definitions and explanations for the use of 

APMs;

 – adequacy of reconciliations to GAAP measures;
 – equal prominence to GAAP measures; and
 – consistency of application, including explanations for any 

changes.

•  Ensured that the disclosures in the financial statements 

appropriately explain to the users the key elements of FY23 
performance that are not expected to recur in future 
periods.

•  The primary team performed centralised procedures over 
the classification and disclosure of non-underlying items, 
and the related risk of material misstatement, in the Group 
consolidated financial statements as a whole.

In the prior year, our auditor’s report included a key audit matter relating to the manipulation of contract performance in Keller Austral. Following the fraud 
investigation performed by management’s appointed specialist, evaluation by our forensics team, as well as the incremental procedures included as part 
of revenue recognition and fraud procedures, we deemed that the manipulation of contract performance in Keller Austral is no longer a separate key audit 
matter. There have been no other changes in our assessment of key audit matters compared with the prior year.

Keller Group plc  Annual Report and Accounts 2023

Independent auditor’s report continued
to the members of Keller Group plc

Our application of materiality 
We apply the concept of materiality in planning and performing the audit, 
in evaluating the effect of identified misstatements on the audit and in 
forming our audit opinion. 

Materiality
The magnitude of an omission or misstatement that, individually or in 
the aggregate, could reasonably be expected to influence the economic 
decisions of the users of the financial statements. Materiality provides a 
basis for determining the nature and extent of our audit procedures.

We determined materiality for the Group to be £7.0m (2022: £4.6m), 
which is 4.6% (2022: 4.9%) of profit before tax adjusted for one-off, 
non-underlying items. We believe that this measure provides us with an 
appropriate materiality basis which excludes non-underlying items, as these 
were identified as a key audit matter which resulted in specific audit focus. 
We determined materiality for the parent company to be £5.3m (2022: 
£4.7m), which is 1% (2022: 1%) of equity. Equity is the most appropriate 
measure given the parent company is an investment holding company with 
no revenue. The materiality determined for the standalone parent company 
financial statements exceeds the Group materiality as it is determined on a 
different basis given the nature of the operations. For the purposes of the 
audit of the Group financial statements, our procedures, including those on 
balances in the parent company that are consolidated, are undertaken with 
reference to the Group assigned materiality and performance materiality 
set out in this report. 

Starting  
basis

•  £125.5m
•  Profit before tax for the year

Adjustments

•  £22.2m
•  Non-underlying items for the year
•  £5.7m 
•  Amortisation of intangibles on acquisition

Materiality

•  Totals £153.4m
•  Materiality of £7.0m (4.6% of profit 
before tax adjusted for one-off, non-
underlying items)

Performance materiality
The application of materiality at the individual account or balance level. It is 
set at an amount to reduce to an appropriately low level the probability that 
the aggregate of uncorrected and undetected misstatements exceeds 
materiality.

On the basis of our risk assessments, together with our assessment 
of the Group’s overall control environment, our judgement was that 
performance materiality was 50% (2022: 50%) of our planning materiality. 
The performance materiality has been set at an underlying basis which is 
consistent with prior year and includes consideration over the risk factors 
relating to the financial reporting issue in Austral in 2022. The profitability 
of the Group has meant that the financial quantum of our performance 
materiality threshold (£3.5m, 2022: £2.3m) has increased compared with 
prior year. 

Audit work at component locations for the purpose of obtaining audit 
coverage over significant financial statement accounts is undertaken 
based on a percentage of total performance materiality. The performance 
materiality set for each component is based on the relative scale and risk 
of the component to the Group as a whole and our assessment of the 
risk of misstatement at that component. In the current year, the range of 
performance materiality allocated to components was £0.7m to £3.15m 
(2022: £0.5m to £1.6m). 

Reporting threshold
An amount below which identified misstatements are considered as being 
clearly trivial.

We agreed with the Audit and Risk Committee that we would report to 
them all uncorrected audit differences in excess of £0.35m (2022: £0.2m), 
which is set at 5% of planning materiality, as well as differences below that 
threshold that, in our view, warranted reporting on qualitative grounds. 

We evaluate any uncorrected misstatements against both the quantitative 
measures of materiality discussed above and in light of other relevant 
qualitative considerations in forming our opinion.

Other information 
The other information comprises the information included in the Annual 
Report and Accounts set out on pages 1 to 218, including the Strategic 
report on pages 1 to 84, and Corporate governance report set out on pages 
85 to 146, other than the financial statements and our auditor’s report 
thereon. The Directors are responsible for the other information contained 
within the annual report. 

During the course of our audit, we reassessed initial materiality noting that 
there was an increase compared with the original assessment attributable 
to the performance and profit before tax of the Group. The underlying basis 
of materiality was not changed compared with the planning stage. 

Our opinion on the financial statements does not cover the other 
information and, except to the extent otherwise explicitly stated in this 
report, we do not express any form of assurance conclusion thereon. 

Our responsibility is to read the other information and, in doing so, consider 
whether the other information is materially inconsistent with the financial 
statements or our knowledge obtained in the course of the audit or 
otherwise appears to be materially misstated. If we identify such material 
inconsistencies or apparent material misstatements, we are required to 
determine whether this gives rise to a material misstatement in the financial 
statements themselves. If, based on the work we have performed, we 
conclude that there is a material misstatement of the other information, we 
are required to report that fact.

We have nothing to report in this regard.

Responsibilities of Directors
As explained more fully in the Directors’ responsibilities statement set 
out on page 146, the Directors are responsible for the preparation of the 
financial statements and for being satisfied that they give a true and fair 
view, and for such internal control as the Directors determine is necessary 
to enable the preparation of financial statements that are free from material 
misstatement, whether due to fraud or error. 

In preparing the financial statements, the Directors are responsible for 
assessing the Group and parent company’s ability to continue as a going 
concern, disclosing, as applicable, matters related to going concern and 
using the going concern basis of accounting unless the Directors either 
intend to liquidate the Group or the parent company or to cease operations, 
or have no realistic alternative but to do so.

Auditor’s responsibilities for the audit of the financial 
statements 
Our objectives are to obtain reasonable assurance about whether the 
financial statements as a whole are free from material misstatement, 
whether due to fraud or error, and to issue an auditor’s report that includes 
our opinion. Reasonable assurance is a high level of assurance, but is not 
a guarantee that an audit conducted in accordance with ISAs (UK) will 
always detect a material misstatement when it exists. Misstatements can 
arise from fraud or error and are considered material if, individually or in the 
aggregate, they could reasonably be expected to influence the economic 
decisions of users taken on the basis of these financial statements. 

Explanation as to what extent the audit was considered 
capable of detecting irregularities, including fraud 
Irregularities, including fraud, are instances of non-compliance with laws and 
regulations. We design procedures in line with our responsibilities, outlined 
above, to detect irregularities, including fraud. The risk of not detecting a 
material misstatement due to fraud is higher than the risk of not detecting 
one resulting from error, as fraud may involve deliberate concealment by, for 
example, forgery or intentional misrepresentations, or through collusion. 
The extent to which our procedures are capable of detecting irregularities, 
including fraud, is detailed below.

However, the primary responsibility for the prevention and detection of 
fraud rests with both those charged with governance of the company and 
management. 

•  We obtained an understanding of the legal and regulatory frameworks 

that are applicable to the Group and determined that the most 
significant are those related to the reporting framework (IFRS, IFRS 
adopted pursuant to FRS 101, United Kingdom Generally Accepted 
Accounting Practice, the Companies Act 2006 and the Corporate 
Governance Code) and the relevant tax compliance regulations in the 
countries of operations of the reporting components. In addition, 
we concluded that there are certain significant laws and regulations 
which may have an effect on the determination of the amounts and 
disclosures in the financial statements. These are based on the nature 
of the Group’s operations and the key geographies in which they 
operate in, and include (but are not limited to): labour and employment 
laws, health and safety, the Modern Slavery Act 2015, the Bribery Act 
2010 and the Listing Rules of the London Stock Exchange.

Opinions on other matters prescribed by the  
Companies Act 2006
In our opinion, the part of the Directors’ remuneration report to be audited 
has been properly prepared in accordance with the Companies Act 2006.

In our opinion, based on the work undertaken in the course of the audit:

• 

• 

the information given in the Strategic report and the Directors’ report 
for the financial year for which the financial statements are prepared is 
consistent with the financial statements; and 
the Strategic report and the Directors’ report have been prepared in 
accordance with applicable legal requirements.

Matters on which we are required to report by exception
In the light of the knowledge and understanding of the Group and the 
parent company and its environment obtained in the course of the audit, 
we have not identified material misstatements in the Strategic report or the 
Directors’ report.

We have nothing to report in respect of the following matters in relation to 
which the Companies Act 2006 requires us to report to you if, in our opinion:

•  adequate accounting records have not been kept by the parent 

• 

company, or returns adequate for our audit have not been received 
from branches not visited by us; or
the parent company financial statements and the part of the 
Directors’ remuneration report to be audited are not in agreement 
with the accounting records and returns; or

•  certain disclosures of Directors’ remuneration specified by law are not 

made; or

•  we have not received all the information and explanations we require 

for our audit.

Corporate Governance Statement
We have reviewed the Directors’ statement in relation to going concern, 
longer-term viability and that part of the Corporate Governance Statement 
relating to the Group and company’s compliance with the provisions of the 
UK Corporate Governance Code specified for our review by the Listing 
Rules.

Based on the work undertaken as part of our audit, we have concluded that 
each of the following elements of the Corporate Governance Statement 
is materially consistent with the financial statements or our knowledge 
obtained during the audit:

•  Directors’ statement with regard to the appropriateness of adopting 
the going concern basis of accounting and any material uncertainties 
identified set out on page 39;

•  Directors’ explanation as to their assessment of the company’s 

prospects, the period this assessment covers and why the period is 
appropriate set out on page 39;

•  Directors’ statement on whether they have a reasonable expectation 
that the Group will be able to continue in operation and meets its 
liabilities set out on page 39;

•  Directors’ statement on fair, balanced and understandable set out on 

page 113;

•  Board’s confirmation that it has carried out a robust assessment of 

• 

• 

the emerging and principal risks set out on pages 40 to 47;
the section of the annual report that describes the review of 
effectiveness of risk management and internal control systems set 
out on pages 40 to 47; and
the section describing the work of the Audit and Risk Committee set 
out on page 113.

Reading

4 March 2024

•  We understood how Keller Group plc is complying with those 
frameworks by making enquiries of management, reviewing 
management procedures for oversight by those charged with 
governance (ie considering the potential for override of controls or 
other inappropriate influence over the financial reporting process, 
such as efforts by management to manage earnings in order to 
influence the perceptions of analysts as to the Group’s performance 
and profitability), the culture of honesty and ethical behaviour and 
whether a strong emphasis is placed on fraud prevention, which may 
reduce opportunities for fraud to take place, and fraud deterrence. 
We corroborated our enquiries through our review of Board minutes, 
discussions with the Audit and Risk Committee, any correspondence 
received from regulatory bodies and those responsible for legal and 
compliance procedures and the Company Secretary.

•  We assessed the susceptibility of the Group’s financial statements to 
material misstatement, including how fraud might occur, by meeting 
with management to understand where they considered there was 
susceptibility to fraud. We also considered performance targets 
and their influence on efforts made by management to manage 
earnings or influence the perceptions of analysts. Where this risk was 
considered to be higher, we performed audit procedures to address 
each identified fraud risk. The key audit matters section above covers 
those procedures performed in areas where we have concluded the 
risks of material misstatement are highest, including where we have 
identified a risk of fraud. These procedures included testing manual 
journal entries, a focus on the recoverability of unbilled revenue, and 
considerations over information produced by the entity including work 
over the authenticity of key evidence received during the audit.
•  Based on this understanding we designed our audit procedures 
to identify non-compliance with such laws and regulations. Our 
procedures involved review of Board minutes to identify non-
compliance with such laws and regulations, review of reporting to 
the Audit and Risk Committee on compliance with regulations and 
enquires of the Company Secretary and management. 

•  We have performed enquires of internal and external legal counsel 
to identify risks of material misstatement. We have made further 
enquiries with project managers to investigate any inconsistencies in 
data prepared by the finance team, including any transfers of costs 
between projects and any unusual build-up of work in progress in 
relation to construction income.

•  We have reviewed the internal audit reports to identify major internal 

control issues. We have discussed the impact of internal audit findings 
with management to understand their plan to prevent any material 
misstatement in addition to supplementing these areas with additional 
audit procedures.

A further description of our responsibilities for the audit of the financial 
statements is located on the Financial Reporting Council’s website at 
www.frc.org.uk/auditorsresponsibilities. This description forms part of our 
auditor’s report.

Keller Group plc  Annual Report and Accounts 2023

Notes to the consolidated financial statements

1 Corporate information
The consolidated financial statements of Keller Group plc and its 
subsidiaries (collectively, the ‘Group’) for the year ended 31 December 2023 
were authorised for issue in accordance with the resolution of the Directors 
on 4 March 2024.

Keller Group plc (the ‘company’) is a public limited company, incorporated 
and domiciled in the United Kingdom, whose shares are publicly traded on 
the London Stock Exchange. The registered office is located at 2 Kingdom 
Street, London W2 6BD. The Group is principally engaged in the provision 
of specialist geotechnical services. Information on the Group’s structure is 
provided in note 10 of the company financial statements.

2 Material accounting policy information

Basis of preparation
In accordance with the Companies Act 2006, these consolidated 
financial statements have been prepared and approved by the Directors 
in accordance with UK adopted international accounting standards. The 
company prepares its parent company financial statements in accordance 
with FRS 101.

The consolidated financial statements have been prepared on an historical 
cost basis, except for derivative financial instruments that have been 
measured at fair value. The carrying values of recognised assets and 
liabilities that are designated as hedged items in fair value hedges that 
would otherwise be carried at amortised cost are adjusted to recognise 
changes in the fair values attributable to the risks that are being hedged 
in effective hedge relationships. The consolidated financial statements 
are presented in pounds sterling and all values are rounded to the nearest 
hundred thousand, expressed in millions to one decimal point, except when 
otherwise indicated.

Prior period business combination measurement adjustment
Under IFRS 3 ‘Business Combinations’ there is a measurement period of 
no longer than 12 months in which to finalise the valuation of the acquired 
assets and liabilities. During the measurement period, the acquirer shall 
retrospectively adjust the provisional amounts recognised at the acquisition 
date to reflect new information obtained about facts and circumstances 
that existed as of the acquisition date and, if known, would have affected 
the measurement of the amounts recognised as of that date. During the 
measurement period, the acquirer shall also recognise additional assets or 
liabilities if new information is obtained about facts and circumstances that 
existed as of the acquisition date and, if known, would have resulted in the 
recognition of those assets and liabilities as of that date.

In the year to 31 December 2022, the Group acquired Nordwest 
Fundamentering AS. Adjustments to the provisional fair values were made 
during the measurement period, as set out in note 5. The impact of the 
measurement period adjustments has been applied retrospectively, 
meaning that the results and financial position for the year to 31 December 
2022 have been restated.

Going concern
In August 2023, the Group received proceeds from a new $300m private 
placement of loan notes. These were used to repay existing borrowings. At 
31 December 2023, the Group had undrawn committed and uncommitted 
borrowing facilities totalling £425.2m, comprising £375m of the unutilised 
portion of the revolving credit facility, £2.8m of other undrawn committed 
borrowing facilities and undrawn uncommitted borrowing facilities of 
£47.4m, as well as cash and cash equivalents of £149.0m. At 31 December 
2023, the Group’s net debt to underlying EBITDA ratio (calculated on an IAS 
17 covenant basis) was 0.6x, well within the limit of 3.0x.

The Group has prepared a forecast of financial projections for the three-
year period to 31 December 2026. The forecast underpins the going 
concern assessment which has been made for the period through to 
31 March 2025, a period of at least 12 months from when the financial 
statements are authorised for issue and aligning with the period in which 
the Group’s banking covenants are tested. The base case reflects the 
assumptions made by the Group with respect to key project wins, organic 
growth and a focus on cost reduction. The forecast shows significant 
headroom and supports the position that the Group can operate within its 
available banking facilities and covenants throughout this period.

The Group’s revolving credit facility falls due in November 2025, eight 
months after the going concern period assessed by management. 
Management assumed the Group will continue to have access to 
this funding throughout the going concern period and the three year 
viability period, on the basis that the Group will either renew the facility 
or have sufficient time to agree an alternative source of finance on 
comparable terms.

For the going concern assessment, management ran a series of downside 
scenarios over the base case forecast to assess covenant headroom 
against available funding facilities. This process involved constructing 
scenarios to reflect the Group’s current assessment of its principal 
risks, including those that would threaten its business model, future 
performance, solvency or liquidity. The principal risks and uncertainties 
modelled by management align with those disclosed within this Annual 
Report and Accounts. 

The following severe but plausible downside assumptions were modelled:

•  Rapid downturn in the Group’s markets resulting in up to a 10% decline 

in revenues;

•  Failure to procure new contracts whilst maintaining appropriate 

margins reducing profits by 0.5% of revenue;
• 
Ineffective execution of projects reducing profits by 1% of revenue;
•  A combination of other principal risks and trading risks materialising 

together reducing profits by up to £20.1m over the period to 31 March 
2025. These risks include changing environmental factors, costs of 
ethical misconduct and regulatory non-compliance, occurrence of 
an accident causing serious injury to an employee or member of the 
public and the cost of a product or solution failure; and

•  Deterioration of working capital performance by 5% of six months’ 

sales.

The financial and cash effects of these scenarios were modelled individually 
and in combination. The focus was on the ability to secure or retain future 
work and potential downward pressure on margins. Management applied 
sensitivities against projected revenue, margin and working capital metrics 
reflecting a series of plausible downside scenarios. Against the most 
negative scenario, mitigating actions were overlaid. These include a range 
of cost-cutting measures and overhead savings designed to preserve 
cash flows. 

Even in the most extreme downside scenario incorporating an aggregation 
of all risks considered, which showed a decrease in operating profit of 26.4% 
and an increase in net debt of 26.7% against the Group’s latest forecast 
profit and cash flow projections for the review period up to 31 March 2025, 
the adjusted projections do not show a breach of covenants in respect of 
available funding facilities or any liquidity shortfall. Consideration was given 
to scenarios where covenants would be breached and the circumstances 
giving rise to these scenarios were considered extreme and remote. 

This process allowed the Board to conclude that the Group will continue 
to operate on a going concern basis for the period through to the end 
of March 2025, a period of at least 12 months from when the financial 
statements are authorised for issue. Accordingly, the consolidated financial 
statements are prepared on a going concern basis.

Climate change 
In preparing the consolidated financial statements, management has 
considered the impact of climate change, particularly in the context of 
the risks identified in the TCFD disclosure on pages 48 to 58. The output 
from the scenario analysis has been considered, particularly the financial 
reporting judgements and estimates in respect of the following areas: 

•  Estimates of future cash flows used in impairment assessments of the 

carrying value of goodwill; 

•  The useful economic life of plant, equipment and other intangible 

assets; and

•  Going concern and viability of the Group over the next three years.

Although the scenario analysis identified a risk of stranded assets as a 
result of increased emission standards, this was in one extreme downside 
scenario and we have not adjusted the useful economic life of any plant or 
equipment as a result. Whilst there is currently no change, management 
are aware of the variable risks arising from climate change and will regularly 
assess these risks against judgement and estimates made in preparation of 
the Group’s financial statements.

Changes in accounting policies and disclosures
New and amended standards and interpretations
The following applicable amendments became effective during the year to 
31 December 2023:

•  Amendments to IAS 8 ‘Definition of Accounting Estimates’.
•  Amendments to IAS 1 and IFRS Practice Statement 2 ‘Disclosure of 

Accounting Policies’.

•  Amendments to IAS 12 ‘Deferred Tax related to Assets and Liabilities 

arising from a Single Transaction’.

•  Amendments to IAS 12 ‘International Tax Reform – Pillar Two Model 

Rules’.

The Group has not early adopted any standard, interpretation or 
amendment that has been issued but are not yet effective. 

IFRS 17 Insurance Contracts
IFRS 17 Insurance Contracts is a new accounting standard for insurance 
contracts covering recognition and measurement, presentation and 
disclosure, replacing IFRS 4 Insurance Contracts. The Group has identified 
that the Standard will impact the results of its captive insurance company 
as it issues re-insurance contracts, however since the contracts insure 
other group companies and there are therefore no insurance contracts 
on a consolidated basis and no transfer of significant insurance risk to the 
group, there is therefore no impact on the Group’s consolidated financial 
statements. 

Amendments	to	IAS	8	‘Definition	of	Accounting	Estimates’
The amendments to IAS 8 clarify the distinction between changes in 
accounting estimates, changes in accounting policies and the correction 
of errors. They also clarify how entities use measurement techniques and 
inputs to develop accounting estimates. The amendments had no impact 
on the Group’s consolidated financial statements. 

Amendments to IAS 1 and IFRS Practice Statement 2 ‘Disclosure of 
Accounting Policies’
The amendments to IAS 1 and IFRS Practice Statement 2 Making Materiality 
Judgements provide guidance and examples to help entities apply 
materiality judgements to accounting policy disclosures. The amendments 
have had no material impact on the Group’s consolidated financial 
statements.

Amendments to IAS 12 ‘Deferred Tax related to Assets and Liabilities 
arising from a Single Transaction’
The amendments to IAS 12 ‘Income Tax’ narrow the scope of the initial 
recognition exception, so that it no longer applies to transactions that give 
rise to equal taxable and deductible temporary differences such as leases 
and decommissioning liabilities. The amendments had no impact on the 
Group’s consolidated financial statements.

Amendments	to	IAS	12	‘International	Tax	Reform	–	Pillar	Two	Model	Rules’
The amendments to IAS 12 have been introduced in response to the 
OECD’s BEPS Pillar Two rules and include: 

•  A mandatory temporary exception to the recognition and disclosure 

of deferred taxes arising from the jurisdictional implementation of the 
Pillar Two model rules; and

•  Disclosure requirements for affected entities to help users of the 

financial statements better understand an entity’s exposure to Pillar 
Two income taxes arising from that legislation, particularly before its 
effective date. 

The UK Government enacted Finance (No 2) Act 2023 on 11 July 2023, 
which includes the Pillar Two legislation introducing a multinational top 
up tax and a domestic minimum top up tax in line with the minimum 15% 
rate in the OECD’s Pillar Two rules. The rules will apply to the Group for the 
financial year commencing on 1 January 2024. The Group has applied the 
exemption in the amendments to IAS 12 (issued in May 2023) and has 
neither recognised nor disclosed information about deferred tax assets and 
liabilities related to Pillar Two income taxes.

Basis of consolidation
The consolidated financial statements consolidate the accounts of 
the parent and its subsidiary undertakings to 31 December each year. 
Subsidiaries are entities controlled by the company. Control exists when 
the company has power over an entity, exposure to variable returns from its 
involvement with the entity and the ability to use its power over the entity 
to affect its returns. Where subsidiary undertakings were acquired or sold 
during the year, the accounts include the results for the part of the year for 
which they were subsidiary undertakings using the acquisition method of 
accounting. Intra-group balances, and any unrealised income and expense 
arising from intra-group transactions, are eliminated in preparing the 
consolidated financial statements.

Joint operations
Where the Group undertakes contracts jointly with other parties, these are 
accounted for as joint operations as defined by IFRS 11. In accordance with 
IFRS 11, the Group accounts for its own share of assets, liabilities, revenues 
and expenses measured according to the terms of the joint operations 
agreement.

Joint ventures
A joint venture is a type of joint arrangement whereby the parties that have 
joint control of the arrangement have rights to the net assets of the joint 
arrangement. The consolidated financial statements incorporate a share of 
the results, assets and liabilities of joint ventures using the equity method of 
accounting, whereby the investment is carried at cost plus post-acquisition 
changes in the share of net assets of the joint venture, less any provision 
for impairment. Losses in excess of the consolidated interest in joint 
ventures are not recognised except where the Group has a constructive 
commitment to make good those losses. The results of joint ventures 
acquired or disposed of during the year are included in the consolidated 
income statement from the effective date of acquisition or up to the 
effective date of disposal, as appropriate.

2 Material accounting policy information continued
Summary of material accounting policy information 
Foreign currencies
The Group’s consolidated financial statements are presented in pounds 
sterling, which is also the parent company’s functional currency. For each 
entity, the Group determines the functional currency and items included 
in the financial statements of each entity are measured using that 
functional currency.

Transactions and balances
Transactions in foreign currencies are initially recorded by the Group’s 
entities at their respective functional currency spot rates at the date the 
transaction first qualifies for recognition.

Monetary assets and liabilities denominated in foreign currencies are 
translated at the functional currency spot rates of exchange at the 
reporting date. Differences arising on settlement or translation of 
monetary items are recognised in the consolidated income statement. 
Non-monetary items that are measured in terms of historical cost in a 
foreign currency are translated using the exchange rates at the dates of the 
initial transactions.

Group companies
On consolidation, the assets and liabilities of foreign operations are 
translated into pounds sterling at the rate of exchange prevailing at 
the reporting date and their income statements are translated at 
exchange rates prevailing at the dates of the transactions. The exchange 
movements arising on translation for consolidation are recognised in 
other comprehensive income (OCI). On disposal of a foreign operation, 
the component of the translation reserve relating to that particular foreign 
operation is reclassified to profit or loss.

Any goodwill arising on the acquisition of a foreign operation and any 
fair value adjustments to the carrying amounts of assets and liabilities 
arising on the acquisition are treated as assets and liabilities of the foreign 
operation and translated at the average rate.

The exchange rates used in respect of principal currencies are:

Revenue from construction contracts
The Group’s operations involve the provision of specialist geotechnical 
services. The majority of the Group’s revenue is derived from construction 
contracts. Typically, the Group’s construction contracts consist of one 
performance obligation; however, for certain contracts (for example 
where contracts involve separate phases or products that are not highly 
interrelated) multiple performance obligations exist. Where multiple 
performance obligations exist, total revenue is allocated to performance 
obligations based on the relative standalone selling prices of each 
performance obligation.

For each contract, revenue is the amount that is expected to be 
received from the customer. Revenue is typically invoiced in stages 
during the contracts, however smaller contracts are usually invoiced 
on completion. Variable consideration and contract modifications are 
assessed on a contract-by-contract basis, according to the terms, facts 
and circumstances of the project. Variable consideration is recognised 
only to the extent that it is highly probable that there will not be a 
significant reversal. 

The effects of contract modifications, including claims to customers, are 
recognised only when the Group considers there is an enforceable right to 
consideration, therefore no revenue is recognised until this point. Operating 
expenses in relation to customer modifications are recognised as incurred. 
Factors indicating an enforceable right to consideration will vary from county 
to country but usually includes written confirmation from the customer. In 
certain circumstances, uncertainty over whether a project will be completed 
or not will mean that it is not appropriate to recognise contracted revenues.

Revenue attributed to each performance obligation is recognised based on 
either the input or the output method. The output method is the Group’s 
default revenue recognition approach. The input method is generally used 
for longer-term, more complex contracts. These methods best reflect the 
transfer of benefits to the customer. 

• 

•  Output method: revenue is recognised on the direct measurement of 
progress based on output, such as units of production relative to the 
total number of contracted production units. 
Input method: revenue is recognised on the percentage of 
completion with reference to cost. The percentage of completion is 
calculated based on the costs incurred to date as a percentage of the 
total costs expected to satisfy the performance obligation. Estimates 
of revenues, costs or extent of progress towards completion are 
revised if circumstances change. Any resulting increases or decreases 
in estimated revenues or costs are reflected in the percentage of 
completion calculation in the period in which the circumstances that 
give rise to the revision become known.

Where the Group becomes aware that a loss may arise on a contract, 
and that loss is probable, full provision is made in the consolidated 
balance sheet; based on the estimated unavoidable costs of meeting the 
obligations of the contract, where these exceed the economic benefits 
expected to be received. The unavoidable costs under a contract reflect the 
least net cost of exiting from the contract, which is the lower of the cost of 
fulfilling it and any compensation or penalties arising from failure to fulfil it.

Incremental bid/tender costs and fulfilment costs are not material to the 
overall contract and are expensed as incurred.

Any revenues recognised in excess of billings are recognised as contract 
assets within trade and other receivables. Any payments received in excess 
of revenue recognised are recognised as contract liabilities within trade and 
other payables.

Revenue from the sale of goods and services
The Group’s revenue recognised from the sale of goods and services 
primarily relates to certain parts of the North America business. These 
contracts typically have a single performance obligation, or a series of 
distinct performance obligations that are substantially the same. There are 
typically two types of contract:

•  Delivery of goods: revenue for such contracts is recognised at a point 

in time, on delivery of the goods to the customer.

•  Delivery of goods with installation and/or post-delivery services: 

revenue for these contracts is recognised at a point in time by 
reference to the date on which the goods are installed and/or 
accepted by the customer. 

Taxes
Current income tax
Current income tax assets and liabilities are measured at the amount 
expected to be recovered from or paid to the taxation authorities. The tax 
rates and tax laws used to compute the amount are those that are enacted 
or substantively enacted at the reporting date in the countries where the 
Group operates and generates taxable income. Current income tax relating 
to items recognised directly in equity is recognised in equity and not in the 
consolidated income statement.

The Group provides for future liabilities in respect of uncertain tax positions 
where additional tax may become payable in future periods. Such provisions 
are based on management’s best judgement of the probability of the 
outcome in reaching agreement with the relevant tax authorities. For 
further information refer to note 12. 

Deferred tax
Deferred tax is provided using the liability method on temporary differences 
between the tax bases of assets and liabilities, and their carrying amounts 
for financial reporting purposes at the reporting date.

Deferred tax is recognised on temporary differences in line with IAS 12 
‘Income Taxes’. Deferred tax assets are recognised when it is considered 
likely that they will be utilised against future taxable profits or deferred 
tax liabilities.

Deferred tax is calculated at the tax rates that are expected to apply in the 
period when the liability is settled or the asset is realised. Deferred tax is 
charged or credited to the income statement, except when it relates to 
items charged or credited directly to equity or to OCI, in which case the 
related deferred tax is also dealt with in equity or in OCI.

The carrying amount of deferred tax assets is reviewed at each reporting 
date and reduced to the extent that it is no longer probable that sufficient 
taxable profit will be available to allow all or part of the deferred tax asset 
to be utilised. Unrecognised deferred tax assets are reassessed at each 
reporting date and are recognised to the extent that it has become 
probable that future taxable profits will allow the deferred tax asset to 
be recovered. 

Deferred tax assets and liabilities are offset when there is a legally 
enforceable right to set off current tax assets against current tax liabilities 
and when they relate to income taxes levied by the same taxation authority 
and the Group intends to settle its current tax assets and liabilities on a 
net basis.

Interest income and expense
All interest income and expense is recognised in the income statement on 
an accruals basis, using the effective interest method.

Employee benefit costs
The Group operates a number of defined benefit pension schemes, and 
also makes payments into defined contribution schemes.

The liability in respect of defined benefit schemes is the present value of 
the defined benefit obligations at the balance sheet date, calculated using 
the projected unit credit method, less the fair value of the schemes’ assets 
where applicable. The Group recognises the administration costs, current 
service cost and interest on scheme net liabilities in the income statement, 
and remeasurements of defined benefit plans in OCI in full in the period 
in which they occur. Any surplus resulting from this calculation is limited to 
the present value of any economic benefits available in the form of refunds 
from the plans or reductions in future contributions to the plans. Where 
there is no legal right to a refund from the plan, the liability is calculated as 
the minimum funding requirement to the plan that exists at the balance 
sheet date.

The Group also has long service arrangements in certain overseas 
countries. These are accounted for in accordance with IAS 19 ‘Employee 
Benefits’ and accounting follows the same principles as for a defined 
benefit scheme.

Payments to defined contribution schemes are accounted for on an 
accruals basis.

Property, plant and equipment
Property, plant and equipment is stated at cost, net of accumulated 
depreciation and accumulated impairment losses, if any. Further details 
are set out in note 16 for impairments recognised in the year. Subsequent 
expenditure on property, plant and equipment is capitalised when it 
enhances or improves the condition of the item of property, plant and 
equipment beyond its original assessed standard of performance. 
Maintenance expenditure is expensed as incurred.

Depreciation
Depreciation is provided to write off the cost less the estimated residual 
value of property, plant and equipment using the straight-line method by 
reference to their estimated useful lives as follows:

Buildings

Plant and equipment

Motor vehicles

Computers

50 years

3 to 12 years

4 years

3 years

Depreciation is not provided for on freehold land.

An item of property, plant and equipment is derecognised upon disposal 
(ie at the date the recipient obtains control) or when no future economic 
benefits are expected from its use or disposal. Any gain or loss arising on 
derecognition of the asset (calculated as the difference between the net 
disposal proceeds and the carrying amount of the asset) is included in the 
income statement when the asset is derecognised.

The residual values, useful lives and methods of depreciation of property, 
plant and equipment are reviewed at each financial year end and adjusted 
where appropriate.

Short-term leases and leases of low-value assets
The Group applies the short-term lease recognition exemption to its short-
term leases of plant, machinery and vehicles (ie those leases that have a 
lease term of 12 months or less from the commencement date and do 
not contain a purchase option). It also applies the lease of low-value assets 
recognition exemption to leases of office equipment that are considered of 
low asset value (below £3,000). Lease payments on short-term leases and 
leases of low-value assets are recognised as an expense on a straight-line 
basis over the lease term.

Business combinations
Business combinations are accounted for using the acquisition method 
as at the acquisition date, which is the date on which control is transferred 
to the Group. Control is the power to govern the financial and operating 
policies of an entity so as to obtain benefits from its activities. In assessing 
control, the Group takes into consideration potential voting rights that 
currently are exercisable. The cost of an acquisition is measured as the 
aggregate of the consideration transferred, which is measured at the 
fair value at the acquisition date. Acquisition-related costs are expensed 
as incurred and included in administrative expenses. Identifiable assets 
acquired and liabilities and contingent liabilities assumed in a business 
combination are measured initially at their fair values at the acquisition 
date. The excess of cost of an acquisition over the fair value of the Group’s 
share of the identifiable net assets acquired, including assets identified as 
intangibles on acquisition, is recorded as goodwill.

The results of subsidiaries which have been disposed are included up to the 
effective date of disposal.

Goodwill
Goodwill is initially measured at cost, being the excess of the aggregate of 
the consideration transferred. After initial recognition, goodwill is measured 
at cost less any accumulated impairment losses. Goodwill is reviewed for 
impairment annually and whenever there is an indication that the goodwill 
may be impaired in accordance with IAS 36, any impairment losses are 
recognised immediately in the income statement. Goodwill arising prior to  
1 January 1998 was taken directly to equity in the year in which it arose. 
Such goodwill has not been reinstated on the balance sheet. For the 
purpose of impairment testing, goodwill acquired in a business combination 
is, from the acquisition date, allocated to each of the Group’s cash-
generating units (CGUs) that are expected to benefit from the combination, 
irrespective of whether other assets or liabilities of the acquiree are 
assigned to those units.

Where goodwill has been allocated to a CGU and part of the operation 
within that unit is disposed of, the goodwill associated with the disposed 
operation is included in the carrying amount of the operation when 
determining the gain or loss on disposal. Goodwill disposed in these 
circumstances is measured based on the relative values of the disposed 
operation and the portion of the CGU retained.

Leases 
The Group assesses at contract inception whether a contract is, or 
contains, a lease. That is, if the contract conveys the right to control the use 
of an identified asset for a period of time in exchange for consideration.

Group as lessee
The Group applies a single recognition and measurement approach for all 
leases, except for short-term leases and leases of low-value assets (less 
than £3,000). The Group recognises lease liabilities to make payments and 
right-of-use assets representing the right to use the underlying assets.

Right-of-use assets
The Group recognises right-of-use assets at the commencement date 
of the lease (ie the date the underlying asset is available for use). Right-of-
use assets are measured at cost, less any accumulated depreciation and 
impairment losses, and adjusted for any remeasurement of lease liabilities. 
The cost of right-of-use assets includes the amount of lease liabilities 
recognised, initial direct costs incurred, and lease payments made at or 
before the commencement date less any lease incentives received. Right-
of-use assets are depreciated on a straight-line basis over the shorter of 
the lease term and estimated useful lives as follows:

Land and buildings

Plant and equipment

Motor vehicles

3 to 15 years

2 to 8 years

3 to 5 years

Right-of-use assets are tested for impairment in accordance with IAS 36 
‘Impairment of Assets’. 

Lease liabilities
At the commencement date of the lease, the Group recognises lease 
liabilities measured at the present value of lease payments to be made over 
the lease term. The lease payments include fixed payments less any lease 
incentives receivable, variable lease payments that depend on an index or 
a rate, and amounts expected to be paid under residual value guarantees. 
The lease payments also include the exercise price of a purchase option 
reasonably certain to be exercised by the Group and payments of penalties 
for terminating a lease, if the lease term reflects the Group exercising the 
option to terminate. Variable lease payments that do not depend on an 
index or a rate are recognised as an expense in the period in which the event 
or condition that triggers the payment occurs.

In calculating the present value of lease payments, the Group uses the 
incremental borrowing rate at the lease commencement date, if the 
interest rate implicit in the lease is not readily determinable. The incremental 
borrowing rate applied to each lease is determined by taking into account 
the risk-free rate of the country where the asset under lease is located, 
matched to the term of the lease and adjusted for factors such as the credit 
risk profile of the lessee. Incremental borrowing rates applied to individual 
leases range from 1.07% to 15.05%.

After the commencement date, the amount of lease liabilities is increased 
to reflect the addition of interest and reduced for the lease payments 
made. In addition, the carrying amount of lease liabilities is remeasured 
if there is a modification, a change in the lease term, a change in lease 
payments (eg changes to future payments resulting from a change in an 
index or rate used to determine such lease payments) or a change in the 
assessment of an option to purchase the underlying asset. The Group’s 
lease liabilities are included in interest-bearing loans and borrowings. Refer 
to note 26 for details.

Other intangible assets
Intangible assets, other than goodwill, include purchased licences, software 
(including internally generated software), customer relationships, customer 
contracts and trade names. Intangible assets are capitalised at cost and 
amortised on a straight-line basis over their useful economic lives from the 
date that they are available for use and are stated at cost less accumulated 
amortisation and impairment losses. The estimated useful economic lives 
are as follows:

Licences

Software

Patents

Customer relationships

Customer contracts

Trade names

1 to 4 years

3 to 7 years

2 to 7 years

5 to 7 years

1 to 2 years

5 to 7 years

Software-as-a-service arrangements 
The Group’s current SaaS arrangements are arrangements in which the 
Group does not control the underlying software used in the arrangement. 

Software development costs incurred to configure or customise application 
software provided under a cloud computing arrangement and associated 
fees are recognised as operating expenses as and when the services are 
received where the costs represent a distinct service provided to the Group. 

When such costs incurred do not provide a distinct service, the costs 
are recognised as expenses over the duration of the SaaS contract. The 
Group capitalises other software costs when the requirements of IAS 38 
‘Intangible Assets’ are satisfied, including configuration and customisation 
costs which are distinct and within the control of the Group. Such software 
costs are capitalised and carried at cost less any accumulated amortisation 
and impairment, and amortised on a straight-line basis over the period 
which the developed software is expected to be used. 

Amortisation commences when the development is complete and the 
asset is available for use and is included in the operating costs item of the 
consolidated income statement. The amortisation is reviewed at least at 
the end of each reporting period and any changes are treated as changes in 
accounting estimates.

Impairment of assets excluding goodwill
The carrying values of property, plant and equipment, right-of-use assets 
and other intangibles are reviewed for impairment when events or changes 
in circumstances indicate the carrying value may be impaired. If any such 
indication exists, the recoverable amount, being the lower of their carrying 
amount and fair value less costs to sell, of the asset is estimated in order to 
determine the extent of impairment loss.

Capital work in progress
Capital work in progress represents expenditure on property, plant and 
equipment in the course of construction. Transfers are made to other 
property, plant and equipment categories when the assets are available  
for use.

Inventories
Inventories are measured at the lower of cost and estimated net realisable 
value with allowance made for obsolete or slow-moving items. Cost 
comprises direct materials and, where applicable, direct labour costs and 
those overheads that have been incurred in bringing the inventories to their 
present location and condition.

Write-downs to net realisable value are made for slow-moving, damaged 
or obsolete items based on evaluations made at the local level by reference 
to frequency of stock turnover or specific factors affecting the items 
concerned.

Assets held for sale
Assets are classified as held for sale if their carrying amount will be 
recovered by sale rather than by continuing use in the business. Assets held 
for sale are measured at the lower of their carrying amount and fair value 
less costs to sell, with reference to comparable market transactions. Assets 
that are classified as held for sale are not depreciated.

Financial instruments
Financial assets and financial liabilities are recognised in the Group’s balance 
sheet when the Group becomes a party to the contractual provisions of the 
instrument. The principal financial assets and liabilities of the Group are as 
follows:

(a) Trade receivables and trade payables
Trade receivables are initially recorded at fair value and subsequently 
measured at cost and reduced by allowances for estimated irrecoverable 
amounts.

Trade receivables and contract assets are stated net of expected credit 
losses (ECLs). At each reporting date, the Group evaluates the estimated 
recoverability of trade receivables and contract assets and records 
allowances for ECLs based on experience. 

The Group applies the simplified approach to measurement of ECLs in 
respect of trade receivables, which requires expected lifetime losses to be 
recognised from initial recognition of the receivable. Immediately after an 
individual trade receivable or contract asset is assessed to be unlikely to 
be recovered, an impairment is recognised as the difference between the 
carrying amount of the receivable and the present value of estimated future 
cash flows. Customer specific factors are considered when identifying 
impairments, which can include the geographic location and credit rating of 
a customer.

Where there are no specific concerns over recovery, other than the 
increasing age of a trade receivable or contract asset balance past payment 
terms, the Group uses a provision matrix, where provision rates are based 
on days past due. The provision matrix used reflects estimates based on 
past experience, current economic factors and consideration of forward-
looking estimates of economic conditions. Generally, trade receivables are 
written-off completely if past due for more than 180 days. Default is defined 
as the point where there is no further legal address available for the Group 
to recover the receivable amount.

The information about the ECLs on the Group’s trade receivables and 
contract assets is disclosed in note 20.

Trade payables that are not interest bearing are initially recognised at fair 
value and carried at amortised cost.

Financial instruments continued
(b) Cash and cash equivalents
Cash and cash equivalents in the balance sheet comprise cash at bank and 
on hand and short-term deposits with a maturity of three months or less. 
For the purpose of the consolidated statement of cash flows, cash and cash 
equivalents consist of cash and short-term deposits, as defined above, net 
of outstanding bank overdrafts as they are considered an integral part of 
the Group’s cash management. Bank overdrafts are included within financial 
liabilities in current liabilities in the balance sheet.

(c)	Bank	and	other	borrowings
Interest-bearing bank and other borrowings are recorded at the fair value 
of the proceeds received, net of direct issue costs. Subsequent to initial 
recognition, borrowings are stated at amortised cost, where applicable.

Bank or other borrowings are derecognised when the obligation under the 
liability is discharged, cancelled or expires. When an existing financial liability 
is replaced by another from the same lender on substantially different 
terms, or the terms of an existing liability are substantially modified, such 
an exchange or modification is treated as the derecognition of the original 
liability and the recognition of a new liability. The difference in the respective 
carrying amounts is recognised in the consolidated income statement.

Financial assets and financial liabilities are offset and the net amount 
is reported in the consolidated balance sheet if there is a currently 
enforceable legal right to offset the recognised amounts and there is an 
intention to settle on a net basis, ie to realise the assets and settle the 
liabilities simultaneously.

(d)	Derivative	financial	instruments	and	hedge	accounting
The Group uses derivative financial instruments to manage interest rate 
risk and to hedge fluctuations in foreign currencies in accordance with its 
risk management policy. In cases where these derivative instruments are 
significant, hedge accounting is applied as described below. The Group 
does not use derivative financial instruments for speculative purposes.

Derivatives are initially recognised in the balance sheet at fair value on 
the date the derivative contract is entered into and are subsequently 
remeasured at reporting periods to their fair values. Derivatives are carried 
as financial assets when the fair value is positive and as financial liabilities 
when the fair value is negative.

Changes in the fair value of the effective portion of derivatives that are 
designated and qualify as cash flow hedges are recognised in other 
comprehensive income (OCI). Changes in the fair value of the ineffective 
portion of cash flow hedges are recognised in the income statement. 
Amounts originally recognised in OCI are transferred to the income 
statement when the underlying transaction occurs or if the transaction 
results in the recognition of a non-financial asset or liability, the amount 
accumulated in equity is included in the initial cost or carrying amount of the 
hedged asset or liability.

Changes in the fair value of derivative financial instruments that do not 
qualify for hedge accounting are recognised in the income statement as 
they arise.

Hedge accounting is discontinued when the hedging instrument expires 
or is sold, terminated, or exercised, or no longer qualifies for hedge 
accounting. At that time, any cumulative gain or loss on the hedging 
instrument recognised in OCI is retained in equity until the hedged 
transaction occurs. If a hedged transaction is no longer expected to occur, 
the net cumulative gain or loss recognised in OCI is transferred to the 
income statement in the period.

For the purpose of hedge accounting, hedges are classified as:

•  Cash flow hedges when hedging the exposure or variability in cash 
flows that is either attributable to a particular risk associated with a 
recognised asset or liability or a highly probable transaction. 

•  Fair value hedges when hedging the exposure to changes in the fair 

value of a recognised asset or liability. 

•  Hedges of a net investment in a foreign operation. 

At the inception of a hedge relationship, the Group formally designates 
and documents the hedge relationship to which it wishes to apply 
hedge accounting and the risk management objective and strategy for 
undertaking the hedge. The documentation includes identification of the 
hedging instrument, the hedged item, the nature of the risk being hedged 
and how the Group will assess whether the hedging relationship meets 
the hedge effectiveness requirements (including the analysis of sources of 
hedge ineffectiveness and how the hedge ratio is determined). A hedging 
relationship qualifies for hedge accounting if it meets all of the following 
effectiveness requirements:

•  There is ‘an economic relationship’ between the hedged item and the 

hedging instrument. 

•  The effect of credit risk does not ‘dominate the value changes’ that 

result from that economic relationship. 

•  The hedge ratio of the hedging relationship is the same as that 

resulting from the quantity of the hedged item that the Group actually 
hedges and the quantity of the hedging instrument that the Group 
actually uses to hedge that quantity of hedged item. 

Provisions
Provisions have been made for employee-related liabilities, restructuring 
commitments, onerous contracts, insured liabilities and legal claims, 
and other property-related commitments. These are recognised as 
management’s best estimate of the expenditure required to settle the 
Group’s liability at the reporting date.

A provision is recognised in the balance sheet when the Group has a 
present legal or constructive obligation as a result of a past event and 
where it is probable that an outflow will be required to settle the obligation 
and the amount of the obligation can be estimated reliably. If the effect is 
material, expected future cash flows are discounted using a current pre-tax 
rate that reflects, where appropriate, the risks specific to the liability. Where 
discounting is used, the increase in the provision due to unwinding the 
discount is recognised as a finance cost. Details of provisions are set out in 
note 24.

Provisions for insured liabilities and legal claims include the full estimated 
value of the liability. Any related insurance reimbursement asset that is 
virtually certain to be received is separately presented gross within trade 
and other receivables or other non-current assets on the consolidated 
balance sheet.

Contingent liabilities
Contingent liabilities are possible obligations of the Group of which the 
timing and amount are subject to significant uncertainty. Contingent 
liabilities are not recognised in the consolidated balance sheet, unless they 
are assumed by the Group as part of a business combination. They are 
however disclosed, unless they are considered to be remote. If a contingent 
liability becomes probable and the amount can be reliably measured it 
is no longer treated as contingent and recognised as a liability on the 
balance sheet.

Contingent assets 
Contingent assets are possible assets of the Group of which the timing and 
amount are subject to significant uncertainty. Contingent assets are not 
recognised in the consolidated balance sheet. They are however disclosed, 
when they are considered to be probable. A contingent asset is recognised 
in the financial statements when the inflow of economic benefits is 
virtually certain. 

Share-based payments
The Group operates a number of equity-settled executive and employee 
share plans. For all grants of share options and awards, the fair value of the 
employee services received in exchange for the grant of share options 
is recognised as an expense, calculated using appropriate option pricing 
models. The total amount to be expensed over the vesting period is 
determined by reference to the fair value of the options granted, excluding 
the impact of any non-market vesting conditions, with a corresponding 
increase in retained earnings. The charge is adjusted to reflect expected 
actual levels of options vesting due to non-market conditions. 

Shares purchased and held in trust in connection with the Group’s 
share schemes are deducted from retained earnings. No gain or loss is 
recognised within the income statement on the market value of these 
shares compared with the original cost.

Segmental reporting
During the year the Group comprised three geographical divisions which 
have only one major product or service: specialist geotechnical services. 
North America; Europe; and Asia-Pacific, Middle East and Africa continue 
to be managed as separate geographical divisions. This is reflected in the 
Group’s management structure and in the segment information reviewed 
by the Chief Operating Decision Maker. 

Dividends
Interim dividends are recorded in the Group’s consolidated financial 
statements when paid. Final dividends are recorded in the Group’s 
consolidated financial statements in the period in which they receive 
shareholder approval.

Non-underlying items
Non-underlying items are disclosed separately in the financial statements 
where it is necessary to do so to provide further understanding of the 
financial performance of the Group. They are items which are exceptional 
by their size and/or are non-trading in nature, including amortisation 
of acquired intangibles, goodwill impairment, restructuring costs and 
other non-trading amounts, including those relating to acquisitions and 
disposals. Tax arising on these items, including movement in deferred tax 
assets arising from non-underlying provisions, is also classified as a non-
underlying item.

Significant accounting judgements, estimates 
and assumptions
The preparation of the Group’s consolidated financial statements 
in conformity with IFRS requires management to make judgements, 
estimates and assumptions that affect the application of policies, 
reported amounts of assets and liabilities, revenue and expenses and the 
accompanying disclosures, and the disclosure of contingent liabilities. The 
estimates are based on historical experience and various other factors 
that are believed to be reasonable under the circumstances, the results 
of which form the basis of making the judgements about carrying values 
of assets and liabilities that are not readily apparent from other sources. 
Uncertainty about these assumptions and estimates could result in 
outcomes that require a material adjustment to the carrying amount of 
assets or liabilities affected in future periods. Actual results may also differ 
from these estimates.

The estimates are reviewed on an ongoing basis. Revisions to accounting 
estimates are recognised in the period in which the estimate is revised if the 
revision affects only that and prior periods, or in the period of the revision 
and future periods if the revision affects both current and future periods.

The key assumptions concerning the future and other key sources of 
estimation uncertainty at the reporting date, that have a significant risk 
of causing a material adjustment to the carrying amounts of assets and 
liabilities within the next financial year, are described below. The Group 
based its assumptions and estimates on parameters available when the 
consolidated financial statements were prepared. Existing circumstances 
and assumptions about future developments, however, may change due to 
market changes or circumstances arising that are beyond the control of the 
Group. Such changes are reflected in the assumptions when they occur.

Construction contracts
The Group’s approach to key estimates and judgements relating to 
construction contracts is set out in the revenue recognition policy. In the 
Group consolidated balance sheet this impacts contract assets, contract 
liabilities and contract provisions (refer to notes 4 and 24). As described in 
the policy the default revenue recognition approach is the output method. 
When revenue is recognised based on the output method, there is little 
judgement involved in accounting for construction contracts as the 
amount of revenue that has not been certified/accepted by the client is 
typically small and is usually based on volumes achieved at agreed rates. 
These contracts can still be subject to claims and variations resulting in an 
adjustment to the revenue recognised.

2 Material accounting policy information continued
Significant accounting judgements, estimates 
and assumptions continued

Construction contracts continued
When revenue is recognised based on the input (cost) method, the main 
factors considered when making estimates and judgements include the 
cost of the work required to complete the contract in order to estimate 
the percentage completion, and the outcome of claims raised against the 
Group by customers or third parties. The Group performed around 5,500 
contracts during 2023, at an average revenue of approximately £540,000 
and a typical range of between £25,000 and £10m in value. The majority of 
contracts were completed in the year and therefore there are no estimates 
involved in accounting for these. For contracts that are not complete at year 
end and revenue is recognised on the input method, the Group estimates 
the total costs to complete in order to measure progress and therefore how 
much revenue to recognise, which may impact the contract asset or liability 
recorded in the balance sheet. The actual total costs incurred on these 
contracts will differ from the estimate at 31 December and it is reasonably 
possible that outcomes on these contracts within the next year could be 
materially different in aggregate to those estimated. Total contract assets 
are £90.9m and contract liabilities are £90.9m at 31 December 2023.

However, due to the level of uncertainty and timing across a large portfolio 
of contracts, which will be at different stages of their contract life, it is not 
practical to provide a quantitative analysis of the aggregated judgements 
that are applied at a portfolio level. The estimated costs to complete are 
management’s best estimate at this point in time and no individual estimate 
or judgement is expected to have a materially different outcome.

In the case of loss-making contracts, a full provision is made based on the 
estimated unavoidable costs of meeting the obligations of the contract, 
where these exceed the economic benefits expected to be received. 
The process for estimating the total cost to complete is the same as for 
in-progress profitable contracts, and will include management’s best 
estimate of all labour, equipment and materials costs required to complete 
the contracted work. All cost to complete estimates involve judgement over 
the likely future cost of labour, equipment and materials and the impact of 
inflation is included if material. The amount included within provisions in 
respect of contract provisions is £41.2m (2022: £37.8m).

As stated in the revenue recognition accounting policy, variable 
consideration is assessed on a contract-by-contract basis, according to 
the terms, facts and circumstances of the project. Variable consideration 
is recognised only to the extent that it is highly probable that there will not 
be a significant reversal; management judgement is required in order to 
determine when variable consideration is highly probable. Uncertainty over 
whether a project will be completed or not can mean that it is appropriate to 
treat the contracted revenue as variable consideration.

Non-underlying items
Non-underlying items are disclosed separately in the financial statements 
where it is necessary to do so to provide further understanding of the 
financial performance of the Group. They are items which are exceptional 
by their size and/or are non-trading in nature, including amortisation 
of acquired intangibles, goodwill impairment, restructuring costs and 
other non-trading amounts, including those relating to acquisitions and 
disposals. Tax arising on these items, including movement in deferred tax 
assets arising from non-underlying provisions, is also classified as a non-
underlying item.

The Group exercises judgement in assessing whether restructuring items 
and the ERP implementation costs should be classified as non-underlying. 
This assessment covers the nature of the item, cause of the occurrence 
and scale of impact of that item on the reported performance. Typically, 
management will categorise restructuring costs incurred to exit a specific 
geography as non-underlying, in addition restructuring programmes which 
are incremental to normal operations undertaken to add value to the 
business are included in non-underlying items. The value of exceptional 
restructuring costs in 2023 (£2.8m) is lower than in 2022 (£5.3m). ERP 
implementation costs are categorised as non-underlying due to the scale 
and length of the project. The nature of the project and costs incurred 
are reviewed on a regular basis to assess the appropriateness of the 
classification as a non-underlying cost.

Carrying value of goodwill
The Group tests annually whether goodwill has suffered any impairment 
in accordance with the accounting policy set out above. Impairment exists 
when the carrying value of an asset or cash-generating unit exceeds 
its recoverable amount, which is the higher of its fair value less costs of 
disposal and its value-in-use. The fair value less costs of disposal calculation 
is based on available market data for transactions conducted at arm’s 
length, for similar assets or observable market prices less incremental 
costs of disposing of the asset. The Group estimates the recoverable 
amount based on value-in-use calculations. The value-in-use calculation is 
based on a discounted cash flow (DCF) model. The cash flows are derived 
from the relevant budget and forecasts for the next three years, including 
a terminal value assumption. The recoverable amount is sensitive to the 
discount rate used for the DCF model as well as the expected future 
cash inflows, growth rates and maintainable earnings assumed within 
the calculation. 

In 2023, management noted sensitivity in the headroom available for 
Keller Canada. The DCF for this CGU is sensitive to the future successful 
execution of the CGU’s business plans to consistently meet forecasted 
margins (which assumes a significant improvement in operating 
performance compared with 2023) by improving project delivery 
and revenue growth. Refer to note 15 for further information.

Deferred tax assets
Deferred tax assets are recognised for unused tax losses and other timing 
differences to the extent that it is probable that future taxable profits will be 
available against which the losses can be utilised. Significant management 
judgement is required to determine the amount of deferred tax assets 
that can be recognised, based upon the likely timing and the level of future 
taxable profits (based on the same Board-approved information to support 
the going concern and goodwill impairment assessments). The Group 
uses judgement in assessing the recoverability of deferred tax assets, for 
which the significant assumption is forecast taxable profits. A 10% shortfall 
in expected profits would have a proportional impact on the value of the 
deferred tax assets recoverable. Deferred tax assets recognised on unused 
tax losses were £10.7m at 31 December 2023 (2022: £14.5m). Refer to 
note 12 for further information. 

Insurance and legal provisions
The recognition of provisions for insurance and legal disputes is subject to 
a significant degree of estimation. In making its estimates, management 
seek specialist input from legal advisers and the Group’s insurance claims 
handler to estimate the most likely legal outcome. Provisions are reviewed 
regularly and amounts updated where necessary to reflect developments 
in the disputes. The ultimate liability may differ from the amount provided 
depending on the outcome of court proceedings and settlement 
negotiations or if investigations bring to light new facts. Refer to note 24 
for further information.

The final contract value will not always have been agreed at the year end. The contract value, and therefore revenue allocated to a performance obligation, 
may change subsequent to the year end as variations and claims are agreed with the customer. The amount of revenue recognised in 2023 from 
performance obligations satisfied in previous periods is £12.4m (2022: £15.7m).

The Group’s order book comprises the unexecuted elements of orders on contracts that have been awarded. Where a contract is subject to variations, only 
secured variations are included in the reported order book. As at 31 December 2023, the total order book is £1,489.1m (2022: £1,407.1m). 

The order book for contracts with a total duration over one year is £463.1m (2022: £384.5m). Revenue on these contracts is expected to be recognised

Trade receivables include invoiced amounts for retentions, which are balances typically payable at the end of a construction project, when all contractual 
performance obligations have been met, and are therefore received over a longer period of time. Included in the trade receivables balance is £156.9m (2022: 
£121.3m) in respect of retentions anticipated to be receivable within one year. Included in non-current other assets is £22.7m (2022: £16.3m) anticipated to 
be receivable in more than one year. All contract assets and liabilities are current.

Prior year acquisitions
GKM	Consultants	Inc.
On 1 May 2022, the Group acquired 100% of the issued share capital of GKM Consultants Inc., an instrumentation and monitoring provider in Quebec, 
Canada, for an initial cash consideration of £3.3m (CAD$5.3m). In addition, contingent consideration is payable dependent on the cumulative EBITDA in the 
three-year period post acquisition. 

At the acquisition date, the fair value of the contingent consideration was £1.2m (CAD $2.0m), based on expected cashflows generated by the business over 
a three year period at that point in time. At 31 December 2022, the fair value of the contingent consideration was revised to £0.9m with the reduction in the 
amount payable recognised in the income statement as a non-underlying item in that year. The maximum value of the contingent consideration is £1.2m, 
the minimum payable would be zero.

The fair value of intangible assets acquired represents the fair value of customer contracts at the date of acquisition, customer relationships and the trade 
name. Goodwill arising on acquisition is attributable to the knowledge and expertise of the assembled workforce, the expectation of future contracts 
and customer relationships and the operating synergies that arise from the Group’s strengthened market position. The goodwill is not expected to be 
deductible for tax purposes. 

Nordwest	Fundamentering	AS
On 15 November 2022, the Group acquired 100% of the issued share capital of Nordwest Fundamentering AS, a small specialist geotechnical contractor 
provider in Norway, for an initial cash consideration of £5.5m (NOK65m). In addition, deferred consideration of £0.5m (NOK6m) is payable. Due to the timing 
of the acquisition, the review of the fair value of net assets acquired was performed in H1 2023. The provisional value of net assets acquired was £1.0m at 
acquisition date, resulting in a goodwill and other intangibles value of £5.3m.

Acquisitions continued
Prior period business combination measurements adjustments 
Under IFRS 3 ‘Business Combinations’ there is a measurement period of no longer than 12 months in which to finalise the valuation of the acquired assets 
and liabilities. During the measurement period, the acquirer retrospectively adjusts the provisional amounts recognised at the acquisition date to reflect any 
new information obtained about facts and circumstances that existed as of the acquisition date and, if known, would have affected the measurement of the 
amounts recognised as of that date. 

The valuation of Nordwest Fundamentering AS acquired assets is now final and the adjustments to the provisional fair values that were made during the 
measurement period are set out in the table below:

On 10 November 2023, the Group disposed of its Cyntech Tanks operation in Canada, a part of Cyntech Construction Ltd, for a total consideration of 
£1.5m (CAD$2.6m), consisting of the sale price of £1.3m (CAD$2.2m) and further sale price adjustments to be paid from the Escrow amount of £0.2m 
(CAD$0.4m). A non-underlying loss on disposal of £0.1m (CAD$0.2m) was recognised.

In 2022, a contingent consideration of £0.7m was received in accordance with the terms of the sale and purchase agreement of Wannenwetsch GmbH, 
which was disposed of in 2020.

 The net impairment loss on trade receivables and contract assets has been reclassified and separated from operating costs, where it was reported in previous periods. Further details of the 
reclassified amounts are outlined in note 7 to the consolidated financial statements. The restatement explained in note 20 has caused a consequential increase of £12.8m in the amount reported 
above for Other operating charges for the prior period.

7 Net impairment loss on trade receivables and contract assets

9 Non-underlying items
Non-underlying items include items which are exceptional by their size and/or are non-trading in nature, including amortisation of acquired intangibles, goodwill 
impairment, restructuring costs and other non-trading amounts, including those relating to acquisitions and disposals. Tax arising on these items, including 
movement in deferred tax assets arising from non-underlying provisions, is also classified as a non-underlying item. These are detailed in the table below.

As underlying results include the benefits of restructuring programmes and acquisitions but exclude significant costs (such as major restructuring costs and 
the amortisation of acquired intangible assets) they should not be regarded as a complete picture of the Group’s financial performance, which is presented 
in its total statutory results. The exclusion of non-underlying items may result in underlying earnings being materially higher or lower than total statutory 
earnings. In particular, when significant impairments and restructuring charges are excluded, underlying earnings will be higher than total statutory earnings.

Non-underlying items in operating costs
ERP implementation costs
The Group is continuing the strategic project to implement a new cloud computing enterprise resource planning (ERP) system across the Group. Due to 
the size, nature and incidence of the relevant costs expected to be incurred, the costs are presented as a non-underlying item, as they are not reflective of 
the underlying performance of the Group. As this is a complex implementation, project costs are expected to be incurred over a total period of five years, of 
which 2023 was the third year. Non-underlying ERP costs of £7.5m (2022: £6.3m) include only costs relating directly to the implementation including external 
consultancy costs and the cost of the dedicated implementation team. Non-underlying costs does not include operational post-deployment costs such as 
licence costs for businesses that have transitioned.

Goodwill impairment
The goodwill impairment of £12.1m relates to Keller Limited, the UK Foundations business following uncertainty over the future profitability of the cash-
generating unit after the completion of a substantial customer contract. Refer to note 15 for further information.

In 2022, the goodwill impairment of £12.5m was related to Austral (£7.7m) due to uncertainty over the future profitability of the cash-generating unit 
following the discovery of the financial reporting fraud; and Sweden (£4.8m) due to a downward revision to the medium-term forecast as forward projections 
did not fully support the carrying value of the goodwill. 

Exceptional restructuring costs
Exceptional restructuring costs of £2.8m. comprise £0.5m in the Europe division, and £2.3m in the Asia-Pacific, Middle East and Africa (AMEA) division. In 
Europe, the costs relate to the exit from Kazakhstan, in AMEA the costs relate to the closure of the Egypt business. In addition, the exit from Kazakhstan 
resulted in a £0.4m impairment of trade receivables.

The Group exercises judgement in assessing whether restructuring items should be classified as non-underlying. This assessment covers the nature of 
the item, cause of the occurrence and scale of impact of that item on the reported performance. Typically, management will categorise restructuring costs 
incurred to exit a specific geography as non-underlying, in addition restructuring programmes which are incremental to normal operations undertaken to 
add value to the business are included in non-underlying items. The value of exceptional restructuring costs in 2023 (£2.8m) is lower than in 2022 (£5.3m).

In 2022, exceptional restructuring costs of £5.3m comprised £3.4m in the North America Division, £1.8m in the Europe Division, a credit of £0.6m in AMEA 
and £0.7m incurred centrally. In North America, the costs arose as a result of a management and property reorganisation within the parts of the business 
located in Texas. Costs include redundancy costs and property duplication costs. In Europe, the costs related to the scheduled exit of the Ivory Coast and 
Morocco businesses, including asset impairments and redundancy costs. In AMEA, the credit arose from restructuring costs provided for in prior years as 
costs incurred were lower than originally anticipated. In 2022, an impairment charge of £0.3m by the North-East Europe Business Unit was in respect of 
trade receivables in Ukraine that were not expected to be recovered due to the ongoing conflict.

Loss on disposal of operations
On 10 November 2023, the Group disposed of its Cyntech Tanks operation in Canada, a part of Cyntech Construction Ltd, for a total consideration of 
£1.5m, consisting of the sale price of £1.3m and further sale price adjustments to be paid from the Escrow amount of £0.2m. A loss on disposal of £0.1m 
was recognised.

In 2022, the £3.5m exceptional charge was related to a provision made for additional legal costs relating to the historical Avonmouth contract dispute 
following a negotiation with insurers during that year. In addition, a £2.5m provision for a legal claim in respect of a closed business was recognised.

Contingent consideration
In 2022, additional contingent consideration payable of £0.1m related to the acquisition of the Geo Instruments US business in 2017. 

Acquisition costs
Acquisition costs of £0.2m in 2022 comprised professional fees relating to the NWF acquisition in Norway and centrally incurred project costs. 

Amortisation of acquired intangible assets
Amortisation of acquired intangible assets of £5.1m relates to the amortisation charge on assets acquired in the RECON, GKM, Moretrench and NWF 
acquisitions. The amortisation in 2022 of £10.3m relates to the RECON, GKM, Moretrench and Voges acquisitions. 

Non-underlying items in other operating income
The gain on disposal of assets held for sale of £0.8m relates primarily to the sale of assets owned by the now closed Waterway business in Australia as 
mentioned in note 22. Impairment charges for these assets had previously been charged to non-underlying items in prior periods and therefore the 
corresponding profit on disposal of the assets is also recognised as a non-underlying item.

During 2022, the second and final instalment of contingent consideration was received in relation to the Wannenwetsch disposal in September 2020, in 
accordance with the terms of the sale and purchase agreement. The first instalment was received during 2021.

Amortisation of joint venture acquired intangibles
Amortisation of joint venture intangibles relates to NordPile, an acquisition by the Group’s joint venture interest KFS Finland Oy on 8 September 2021.

Non-underlying finance income
In 2022, the Group entered into an interest rate derivative with the purpose of hedging a highly probable forecast transaction. The forecast transaction did 
not take place and as a result the amount arising from the hedging instrument was recognised in the income statement. This resulted in the recognition of 
£3.6m of finance income which was included in non-underlying as it was material in size and was not reflective of the underlying finance income and costs of 
the Group.

The increase in the effective tax rate on underlying profits of 25% from the 2022 rate of 22% is largely due to increased profits in the US (which are taxed at 
a higher combined federal and state tax rate), non-deductible accounting provisions in Saudi Arabia and material accounting losses in Sweden, Norway and 
Poland where no deferred tax asset is recognised.

The tax credit of £3.0m on non-underlying items has been calculated by assessing the tax impact of each component of the charge to the income 
statement and applying the jurisdictional tax rate that applies to that item. The effective tax rate in 2023 on non-underlying items is lower than the effective 
tax rate on underlying items due to the inclusion of costs for which there is no corresponding tax credit. In 2022, £4.7m of the non-underlying tax credit 
related to the tax impact of the non-underlying loss for the year. The remainder of the FY22 credit arose from the reversal of the valuation allowance against 
deferred tax assets in Canada that was recognised through the non-underlying tax charge in prior years. 

The Group is subject to taxation in over 40 countries worldwide and the risk of changes in tax legislation and interpretation from tax authorities in the 
jurisdictions in which it operates. The assessment of uncertain positions is subjective and subject to management’s best judgement of the probability of 
the outcome in reaching agreement with the relevant tax authorities. Where tax positions are uncertain, provisions are made where necessary, based on 
interpretation of legislation, management experience and appropriate professional advice. Management do not expect the outcome of these estimates to 
be materially different from the position taken.

The UK government enacted Finance (No 2) Act 2023 on 11 July 2023, which includes the Pillar Two legislation introducing a multinational top up tax and 
a domestic minimum top up tax in line with the minimum 15% rate in the OECD’s Pillar Two rules. The rules will apply to the Group for the financial year 
commencing on 1 January 2024. The UK legislation has also adopted the OECD’s transitional Pillar Two safe harbour rules which, if applicable, will deem the 
top up tax for a jurisdiction to be nil based on available Country-by-Country Reporting data. 

The Group has performed an assessment of the potential exposure to Pillar Two top up taxes, based on the most recent Country-by-Country Reporting, 
and FY24 country specific PBT forecasts for the constituent entities in the Group. Based on the assessment, the Pillar Two effective tax rates in most of the 
jurisdictions in which the Group operates are above 15%. There are however a limited number of jurisdictions where the transitional safe harbour relief may 
not apply and the Pillar Two effective tax rate is close to the 15% threshold. The Group does not expect a material exposure to Pillar Two top up taxes for 
these jurisdictions.

The Group has applied the exemption in the amendments to IAS 12 (issued in May 2023) and has neither recognised nor disclosed information about 
deferred tax assets or liabilities relating to Pillar Two income taxes.

The movement from a net deferred tax asset of £9.8m at 31 December 2022 to £29.0m at 31 December 2023 is largely as a result of the timing of the 
deductibility of R&D expenditure for US tax purposes. R&D expenditure is capitalised for tax purposes and amortised over five years.

Deferred tax assets include amounts of £36.8m (2022: £15.1m) where recovery is based on forecasts of future taxable profits that are expected to be 
available to offset the reversal of the associated temporary differences. The deferred tax assets arise predominantly in the US (£29.3m) Australia (£3.7m), 
Canada (£2.1m), India (£1.0m) and the UK (£0.7m). The amount of profits in each territory which are necessary to be realised over the forecast period to 
support these assets are £115m, £12m, £7m, £4m and £3m. Canadian tax rules currently allow tax losses to be carried forward up to 20 years. Australia 
and the UK allow losses to be carried forward indefinitely. The recovery of deferred tax assets has been assessed by reviewing the likely timing and level of 
future taxable profits. The period assessed for recovery of assets is appropriate for each territory having regard to the specific facts and circumstances 
and the probability of achieving forecast profitability. A 10% shortfall in expected profits would have a proportional impact on the value of the deferred tax 
assets recoverable.

The following is the analysis of the deferred tax balances:

At the balance sheet date, the Group had unused tax losses of £137.6m (2022: £140.9m), mainly arising in Canada, Australia, Malaysia and the UK, available 
for offset against future profits, on which no deferred tax asset has been recognised. Of these losses, £84.0m (2022: £118.2m) may be carried forward 
indefinitely. Of the remaining losses, £15.6m expire in 2025, £3.4m expire in 2028 and £34.6m expire in 2035.

At the balance sheet date, the aggregate of other deductible temporary differences for which no deferred tax asset has been recognised was £4.4m (2022: 
£18.0m). These differences have no expiry term.

At the balance sheet date the aggregate of temporary differences associated with investments in subsidiaries, branches and joint ventures for which no 
deferred tax liability has been recognised is £373.9m (2022: £335.0m), on the basis that the Group can control the reversal of temporary differences and it is 
probable that the temporary differences will not reverse in the foreseeable future. The unprovided deferred tax liability in respect of these timing differences 
is £10.0m (2022: £10.2m).

The Board has recommended a final dividend for the year ended 31 December 2023 of £22.7m, representing 31.3p (2022: 24.5p) per share. The 
proposed dividend is subject to approval by shareholders at the Annual General Meeting on 15 May 2024 and has not been included as a liability in 
these financial statements.

14 Earnings per share
Basic earnings per share is calculated by dividing the profit for the year attributable to ordinary equity holders of the parent by the weighted average number 
of ordinary shares outstanding during the year.

When the Group makes a profit, diluted earnings per share equals the profit attributable to equity holders of the parent adjusted for the dilutive impact 
divided by the weighted average diluted number of shares. When the Group makes a loss, diluted earnings per share equals the loss attributable to the 
equity holders of the parent divided by the basic average number of shares. This ensures that earnings per share on losses is shown in full and not diluted by 
unexercised share awards.

There have been no other transactions involving ordinary shares or potential ordinary shares between the reporting date and the date of authorisation of 
these financial statements.

Basic and diluted earnings per share are calculated as follows:

In the 2022 financial year, goodwill arising on the acquisition of business relates to Nordwest Fundamentering AS.

Other intangibles represent internally developed software and licences. There are no indicators of impairment for assets relating to trade names, 
customer contracts and relationships or other intangibles at 31 December 2023. 

For the purposes of impairment testing, goodwill has been allocated to seven (2022: ten) separate cash-generating units (CGUs). The carrying amount of 
goodwill allocated to the five CGUs with the largest goodwill balances is significant in comparison to the total carrying amount of goodwill and comprises 
99% of the total (2022: 95%). The relevant CGUs and the carrying amount of the goodwill allocated to each are as set out below, together with the pre-tax

Keller Group plc  Annual Report and Accounts 2023

The recoverable amount of the goodwill allocated to each CGU has been calculated on a value-in-use basis. The calculations use cash flow projections 
based on financial budgets and forecasts approved by management and cover a three-year period.

The Group’s businesses operate in a diverse geographical set of markets, some of which are expected to continue to face uncertain conditions in future 
years. The most important factors in the value-in-use calculations are the forecast revenues and operating margins during the forecast period, the growth 
rates and discount rates applied to future cash flows. The key assumptions underlying the cash flow forecasts are revenue and operating margins assumed 
throughout the forecast period. Revenue and operating margins are prepared as part of the Group’s three-year forecast in line with the Group’s annual 
business planning process. The Group’s budget for 2024 and financial projections for 2025 and 2026 were approved by the Board, and have been used as 
the basis for input into the value-in-use calculation. 

Management considers all the forecast revenues, margins and profits to be reasonably achievable given recent performance and the historic trading results 
of the relevant CGUs. A margin for historical forecasting error has also been factored into the value-in-use model. Cash flows beyond 2026 which are 
deemed to be on a continuing basis have been extrapolated using the forecast growth rates above and do not exceed the long-term average growth rates 
for the markets in which the relevant CGUs operate. The growth rates used in the Group’s value-in-use calculation into perpetuity are based on forecasted 
growth in the construction sector in each region where a CGU is located and adjusted for longer-term compound annual growth rates for each CGU as 
estimated by management. The discount rates used in the value-in-use calculations are based on the weighted average cost of capital of companies 
comparable to the relevant CGUs, adjusted as necessary to reflect the risk associated with the asset being tested. 

Management’s assessment for Keller Canada is sensitive to the future successful execution of CGU’s business plans to consistently meet forecasted 
margins (which assumes a significant improvement in operating performance compared with 2023) by improving project delivery and revenue growth.

The goodwill in Keller Limited, included in the table above, was impaired by £12.1m during 2023. The goodwill is impaired due to the uncertainty in the CGU’s 
business plans to address the quantum of reduction in revenue volumes, margins and profits following scheduled completion of HS2 projects within the next 
twelve months.

For the remaining CGUs, management believes that any reasonable possible change in the key assumptions on which the recoverable amounts of the CGUs 
are based would not cause any of their carrying amounts to exceed their recoverable amounts. 

A number of sensitivities were run on the projections to identify the changes required in each of the key assumptions that, in isolation, would give rise to an 
impairment of the following goodwill balances.

16 b) Right-of-use assets – leased assets
The Group has lease contracts for various items of land and buildings, plant, machinery and vehicles used in its operations. Leases of land and buildings 
generally have lease terms between three and 15 years, while plant, machinery and vehicles generally have lease terms between two and eight years. The 
Group’s obligations under its leases are secured by the lessor’s title to the lease assets. Generally, the Group is restricted from assigning and sub-leasing its 
leased assets. There are several lease contracts that include extension and termination options.

The Group has certain leases of machinery with lease terms of 12 months or less and leases of office equipment with low value. The Group applies the 
‘short-term lease’ and ‘lease of low-value assets’ recognition exemptions for these leases.

Set out below are the carrying amounts of the right-of-use assets recognised and the movements during the year:

A non-qualifying deferred compensation plan (NQ) is available to US employees, whereby an element of eligible employee bonuses and salary is deferred 
over a period of four to six years. The plan allows participants to receive tax relief for contributions beyond the limits of the tax-free amounts allowed per the 
401k defined contribution pension plan. The plan is administered by a professional investment provider with participants able to select their investments 
from an approved listing. An amount equal to each participant’s compensation deferral is transferred into a trust and invested in various marketable 
securities. The related trust assets are not identical to investments held on behalf of the employee but are invested in similar funds with the objective that 
performance of the assets closely tracks the liabilities. The investments held in the trust are designated solely for the purpose of paying benefits under 
the non-qualified deferred compensation plan. The investments in the trust would however be available to all unsecured general creditors in the event 
of insolvency.

The value of both the employee investments and those held in trust by the company are measured using Level 1 inputs per IFRS 13 (‘quoted prices in active 
markets for identical assets or liabilities that the entity can access at the measurement date’) based on published market prices at the end of the period. 
Adjustments to the fair value are recorded within net finance costs in the consolidated income statement. 

At 31 December 2023, non-current assets in relation to the investments held in the trust were £20.5m (2022: £19.4m). The fair value movement on these 
assets was £2.2m (2022: £3.5m). During the period proceeds from the sale of NQ-related investments were £nil (2022: £nil). At 31 December 2023, non-
current liabilities in relation to the participant investments were £14.3m (2022: £14.7m). These are accounted for as financial liabilities at fair value through 
profit or loss. The fair value movement on these liabilities was £2.6m (2022: £3.5m). During the year £0.6m (2022: £1.2m) of compensation was deferred

Further details on insurance receivables are given in note 24.

During the year, the Financial Reporting Council (“FRC”) reviewed the Group’s Annual Report and Accounts for the year ended 31 December 2022. The FRC’s 
review was limited to the Group’s Annual Report and Accounts for the year ended 31 December 2022 and did not benefit from a detailed understanding of 
underlying transactions and therefore provided no assurance that they are correct in all material respects. Following completion of the review, the Directors 
have concluded to restate the opening trade and other receivables balance of the prior period by £18.9m and the amounts presented in the Unused 
amounts reversed. The restatement has no impact on the value of the allowance as at 31 December 2022 and has no impact on the statement of financial 
position at 31 December 2022. The restatement has caused a consequential increase of £12.8m in the amount reported in note 6 for Other operating 
charges for the prior period.

43% in 2022 to 46% in 2023. This was as a result of specific provisions that were provided in relation to both customers struggling financially and contractual 
disputes leading to failure of recovery. The other expected credit loss rates were in line with the prior year.

Employee provisions
Employee provisions relate to various liabilities in respect of employee rights and benefits, including the workers’ compensation scheme in North America 
and long service leave benefits in Australia. 

At 31 December 2023, the provision in respect of workers’ compensation was £6.5m (2022: £7.1m). A provision is recognised when an employee informs 
the company of a workers’ compensation claim. The provision is measured based on information provided by the workers’ compensation insurer. The actual 
costs that may be incurred in respect of these claims are dependent on the assessment of an employee’s claim and potential medical expenses, with timing 
of outflows variable depending on the claim.

At 31 December 2023, the provision in respect of long service leave was £2.0m (2022: £1.9m). A provision is recognised at the point an employee joins the 
company, with an adjustment made to factor the likelihood that the employee will remain in continuous service with the company to meet the threshold to 
receive the benefits. It is measured on an IAS 19 basis, at the present value of expected future benefit for services provided by employees up to the reporting 
date. The actual costs that may be incurred are dependent on the length of service for employees and amended for any starters and leavers. The provision is 
utilised when the leave is taken by the employee or when unused leave is paid on termination of employment. 

Employee provisions also includes an amount of £0.8m (2022: £0.8m) in respect of social security contributions on share options. This provision is utilised as 
the options are exercised by employees, which occurs when the awards vest. The provision covers three years of open share options and will be utilised each 
year as the options vest.

Keller Group plc  Annual Report and Accounts 2023

24 Provisions continued
Restructuring provisions
A restructuring provision is recognised when the Group has developed a detailed formal plan for the restructuring, has raised a valid expectation in those 
individuals affected and liabilities have been identified. The measurement of a restructuring provision includes only the direct expenditures arising from 
the restructuring. 

The restructuring provisions in 2023 include amounts provided in the year for the exit from the Egypt business, as well as amounts not yet settled from 
restructuring projects provided in the prior year. The provisions comprise mainly amounts for redundancy costs. Estimates may differ from the actual 
charges depending on the finalisation of redundancy amounts. These provisions are expected to be utilised within the next 12 months

Contract provisions
Contract provisions include onerous contracts where the forecast costs of completing the contract exceed the revenue and provision for potential 
remediation costs that we believe are probable to incur. 

Provision for onerous contracts is made in full when such losses are foreseen, based on the estimated unavoidable costs of meeting the obligations of the 
contract, where these exceed the economic benefits expected to be received. The unavoidable costs under a contract reflect the least net cost of exiting 
from the contract, which is the lower of the cost of fulfilling it and any compensation or penalties arising from failure to fulfil it. The actual loss incurred is 
uncertain until the project has been completed, and the actual costs incurred to complete the contract could be higher or lower than estimated in the 
calculation of the provision. The majority of this balance is expected to be utilised in the next 12 months, given the general short-term nature of contracts. 

Provision for potential remediation costs typically arise after the completion of a project through a customer claim or dispute. The provision reflects our 
estimate of costs to be incurred in relation to the dispute, some disputes can take a long period of time to resolve and the actual amount incurred could be 
higher or lower than our provision, so there is uncertainty over both the amount and the timing of the expected cash outflows. The non-current element of 
the provision relates to disputes we expect will take longer than a year to resolve.

Insurance and legal provisions
Insurance and legal provisions comprises the liability for legal claims against the Group, including those that are retained within the Group’s captive insurer 
(the ‘captive’). The captive covers both public liability and professional indemnity claims for the Group. The captive covers liabilities below an upper limit above 
which third-party insurance applies. They also include matters relating to separate legal issues which are not covered by the captive, including claims arising 
from civil matters which could result in penalties and legal costs. By their nature the amounts and timings of any outflows are difficult to predict.

Provisions for insurance and legal claims are made based on the best estimate of the likely total settlement value of a claim against the Group. Management 
seek specialist input from legal advisers and the Group’s insurance claims handler to estimate the most likely legal outcome. The outcome of legal 
negotiations is inherently uncertain; as a result, there can be no guarantee that the assumptions used to estimate the provision will result in an accurate 
prediction of the actual costs that may be incurred. 

A provision is recognised when it is judged likely that a legal claim will result in a payment to the claimant and the amount of the claim can be reliably 
estimated. Provisions are utilised as insurance claims are settled, which may take a number of years. A separate insurance receivable is recognised to the 
extent that confirmed third-party insurance is expected to cover any element of an estimated claim value and is virtually certain to be recovered. The asset 
is recognised within other non-current assets (refer to note 18) and trade and other receivables (refer to note 20). Management considers that there are no 
instances of reimbursable assets which are probable in nature.

Other provisions
Other provisions are in respect of property dilapidation arising from lease obligations and other operational provisions. Where a lease includes a ‘make-good’ 
requirement, provision for the cost is recognised as the obligation is incurred, either at the commencement of the lease or as a consequence of using the 
asset, and the cost of the expected work required can be reliably estimated. These are expected to be utilised over the relevant lease term which ranges 
from 3 to 15 years across the Group.

26 Financial instruments
Exposure to credit, interest rate and currency risks arise in the normal course of the Group’s business and have been identified as risks for the Group. 
Derivative financial instruments are used to hedge exposure to fluctuations in foreign exchange and interest rates.

The Group does not trade in financial instruments nor does it engage in speculative derivative transactions.

Currency risk
The Group faces currency risk principally on its net assets, most of which are in currencies other than sterling. The Group aims to reduce the impact that 
retranslation of these net assets might have on the consolidated balance sheet by matching the currency of its borrowings, where possible, with the 
currency of its assets. The majority of the Group’s borrowings are held in sterling and US dollars.

The Group manages its currency flows to minimise transaction exchange risk. Forward contracts are used to hedge significant individual transactions. 
The majority of such currency flows within the Group relate to the repatriation of profits, intra-group loan repayments and any foreign currency cash flows 
associated with acquisitions. The Group’s treasury risk management is performed at the Group’s head office.

As at 31 December 2023, the fair value of outstanding foreign exchange forward contracts was £0.3m (2022: £nil) included in current liabilities.

Interest rate risk
Our objectives are to add stability to the interest expense and to manage our exposure to interest rate movements. To accomplish these objectives, we 
primarily use external debt and have previously used interest rate swaps as part of our interest rate risk management strategy.

Interest rate risk is managed by either fixed or floating rate borrowings dependent upon the purpose and term of the financing.

As at 31 December 2023, approximately 99% (2022: 80%) of the Group’s third-party borrowings were at fixed interest rates.

Hedging currency risk and interest rate risk
The Group currently hedges currency risk and has previously hedged interest rate risk. Where hedging instruments are used to hedge significant individual 
transactions, the Group ensures that the critical terms, including dates, currencies, nominal amounts, interest rates and lengths of interest periods, are 
matched. The Group uses both qualitative and quantitative methods to confirm this and to assess the effectiveness of the hedge.

Interest rate swaps were in place at the beginning of 2022, to hedge the interest rate risk on the existing US Private placement notes. These interest rate 
swaps were closed out during 2022. There are no derivatives or other hedging instruments in place at the balance sheet date held for the purpose of 
hedging interest rate risk.

Credit risk
The Group’s principal financial assets are trade and other receivables, bank and cash balances and a limited number of investments and derivatives held to 
hedge certain Group exposures. These represent the Group’s maximum exposure to credit risk in relation to financial assets.

The Group has procedures to manage counterparty risk and the assessment of customer credit risk is embedded in the contract tendering processes.  
The counterparty risk on bank and cash balances is managed by limiting the aggregate amount of exposure to any one institution by reference to their credit 
rating and by regular review of these ratings.

Customer credit risk is mitigated by the Group’s relatively small average contract size and diversity, both geographically and in terms of end markets. 
No individual customer represented more than 4% of revenue in 2023 (2022: 6%). The ageing of trade receivables that were past due but not impaired is 
shown in note 20.

The Group evaluates each new customer and assesses their creditworthiness before any contract is undertaken.

The Group reviews customer receivables (including contract assets) on an ageing basis and provides against expected unrecoverable amounts. 
Experience has shown the level of historical provision required to be relatively low. Credit loss provisioning reflects past experience, economic factors 
and specific conditions.

The Group’s estimated exposure to credit risk for trade receivables and contract assets is disclosed in note 20. This amount is the accumulation of several 
years of provisions for known or expected credit losses.

Liquidity risk and capital management
The Group’s capital structure is kept under constant review, taking into account the need for availability and cost of various sources of funding. The capital 
structure of the Group consists of net debt and equity as shown in the consolidated balance sheet. The Group maintains a balance between the certainty of 
funding and a flexible, cost-effective financing structure, with all main borrowings being from committed facilities. The Group’s policy ensures that its capital 
structure is appropriate to support this balance and the Group’s operations.

In order to maintain or adjust the capital structure, the Group may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue 
new shares or sell assets to reduce debt. The Group’s debt and committed facilities mainly comprise a $75m private placement repayable in December 
2024, a US$120m private placement repayable in August 2030, a US$180m private placement repayable in August 2033 and a £375m syndicated revolving 
credit facility expiring in November 2025.

The private placement debt and revolving credit facility are subject to certain covenants linked to the Group’s financing structure, specifically regarding 
the ratios of net debt and interest to profit. The covenants are calculated on an IAS 17 basis, EBITDA to net debt leverage must be below three times and 
EBITDA interest cover must be above four times. The Group has complied with these covenants throughout the year.

At the year end, the Group also had other borrowing facilities available of £50.2m (2022: £75.8m). 

Private placements
In August 2023, $120m and $180m were raised through a private placement with US institutions. The proceeds of the issue of $120m Series A notes 6.38% 
due 2030 and $180m Series B notes 6.42% due 2033 were used to repay a $115m bilateral term loan facility and to repay drawings from the revolving credit 
facility. The US private placement notes are accounted for on an amortised cost basis and are retranslated at the exchange rate at each period end. The 
carrying value of the $120m and $180m private placement liabilities at 31 December 2023 were £94.2m and £141.2m, respectively. 

In December 2014, $75m was raised through a private placement with US institutions. The proceeds of the issue of $75m Series B notes 4.17% due 2024 
was used to refinance maturing private placements. The US private placement note are accounted for on an amortised cost basis and are retranslated at the 
exchange rate at each period end. The carrying value of the $75m private placement liability at 31 December 2023 was £58.5m (2022: £62.0m). 

Hedging
The Group entered into a Treasury lock on 28 April 2023 designated as a cash flow hedge against the highly probable cash outflows for the US private 
placement notes issued in August 2023. A Treasury lock is a synthetic forward sale of a US Treasury note, which is settled in cash based upon the difference 
between an agreed-upon treasury rate and the prevailing treasury rate at settlement. Such Treasury locks are entered into to effectively fix the underlying 
treasury rate component of an upcoming debt issuance. The Treasury lock was settled on 26 May 2023.

All hedges are tested for effectiveness every six months. All hedging relationships remained effective during the year while they were in place.

The Group has substantial borrowing facilities available to it. The undrawn committed facilities available at 31 December 2023 amounted to £377.8m (2022: 
£227.6m). This mainly comprised the Group’s unutilised £375m revolving credit facility, which expires on 23 November 2025. In addition, the Group had undrawn 
uncommitted borrowing facilities totalling £47.4m at 31 December 2023 (2022: £46.1m). Other uncommitted bank borrowing facilities are normally reaffirmed 
by the banks annually, although they can theoretically be withdrawn at any time. Facilities totalling £nil (2022: £1.5m) are secured against certain assets. Future 
obligations under finance leases on a former IAS 17 basis totalled £0.5m (2022: £0.9m), including interest of £0.1m (2022: £0.1m).

Fair values
The fair values of the Group’s financial assets and liabilities are not materially different from their carrying values. The following summarises the major 
methods and assumptions used in estimating the fair values of financial instruments; being derivatives, interest-bearing loans and borrowings, contingent 
and deferred consideration and payables, receivables and contract assets, cash and cash equivalents. 

Derivatives
The fair values of foreign currency forward contracts are calculated based on achieved contract rates compared to the prevailing market rates at the balance 
sheet date. The valuation methods of all of the Group’s derivative financial instruments carried at fair value are categorised as Level 2. Level 2 assets are 
financial assets and liabilities that do not have regular market pricing, but whose fair value can be determined based on other data values or market prices.

Interest-bearing loans and borrowings
Fair value is calculated based on expected future principal and interest cash flows discounted using appropriate discount rates prevailing at the balance 
sheet date.

Contingent and deferred consideration
Fair value is calculated based on the amounts expected to be paid, determined by reference to forecasts of future performance of the acquired businesses, 
discounted using appropriate discount rates prevailing at the balance sheet date and the probability of contingent events and targets being achieved.

The valuation methods of the Group’s contingent consideration carried at fair value are categorised as Level 3. Level 3 assets are financial assets and 
liabilities that are considered to be the most illiquid. Their values have been estimated using available management information, including subjective 
assumptions. The individually significant unobservable inputs used in the fair value measurement of the Group’s contingent consideration as at 31 
December 2023 are the estimation of future profits at Keller Arabia and at GKM in order to determine the expected outcome of the earnout arrangement.

The following table shows a reconciliation from the opening to closing balances for contingent and deferred consideration:

On 29 August 2023, the Group acquired the 35% interest in the voting shares of Keller Turki Company Limited. A contingent consideration is payable 
annually between the years 2023 and 2027, dependent on the qualifying revenue generated by the business for each of those years. The fair value of the 
contingent consideration as at 31 December 2023 was £9.3m (SAR 43.2m).

On 1 May 2022, the Group acquired GKM Consultants Inc. Contingent consideration is payable dependent on the cumulative EBITDA in the three-year 
period post acquisition. The fair value of the contingent consideration was recognised at the date of acquisition at £1.2m, but subsequently reduced 
following movements in its fair value to £0.9m at 31 December 2022. On 15 November 2022, the Group acquired Nordwest Fundamentering AS and the 
deferred contingent consideration payable relating to this acquisition is £0.5m.

Additional deferred consideration provided of £0.2m relates to the Voges Drilling acquisition in 2021. 

Total contingent and deferred consideration of £0.2m was paid during the period in respect of the Voges Drilling acquisition in 2021. 

There were no fair value movements during the year. In 2022, fair value movements of £0.7m related to a fair value adjustment of the RECON contingent 
consideration on finalisation of the amount payable of £0.3m and the reduction in the GKM payable noted above of £0.4m.

Payables, receivables and contract assets
For payables, receivables and contract assets with an expected maturity of one year or less, the carrying amount is deemed to reflect the fair value. 

Non-qualifying deferred compensation plan assets and liabilities
The value of both the employee investments and those held in trust by the company are measured using Level 1 inputs per IFRS 13 (‘quoted prices in active 
markets for identical assets or liabilities that the entity can access at the measurement date’) based on published market prices at the end of the period. 
Adjustments to the fair value of the assets and related liabilities are recorded within net finance costs in the consolidated income statement. 

Refer to note 18 for further information on the non-qualifying deferred compensation plan.

Sensitivity analysis
At 31 December 2023, it is estimated that a general movement of one percentage point in interest rates would increase or decrease the Group’s profit 
before taxation by approximately £nil (2022: £1.5m).

It is estimated that a general increase of 10 percentage points in the value of sterling against other principal foreign currencies would have decreased the 
Group’s profit before taxation and non-underlying items by approximately £14m for the year ended 31 December 2023 (2022: £8.8m). The estimated 
impact of a 10 percentage point decrease in the value of sterling is an increase of £17m (2022: £7.2m) in the Group’s profit before taxation and non-
underlying items. This sensitivity relates to the impact of retranslation of foreign earnings only. The impact on the Group’s earnings of currency transaction 
exchange risk is not significant. These sensitivities assume all other factors remain constant.

The company has one class of ordinary shares, which carries no rights to fixed income. There are no restrictions on the transfer of these shares.

The capital redemption reserve of £7.6m is a non-distributable reserve created when the company’s shares were redeemed or purchased other than from 
the proceeds of a fresh issue of shares.

The other reserve of £56.9m is a non-distributable reserve created when merger relief was applied to an issue of shares under section 612 of the 
Companies Act 2006 to part-fund the acquisition of Keller Canada. The reserve becomes distributable should Keller Canada be disposed of.

As at 31 December 2023, the total number of shares held in treasury was 323,133 (2022: 328,954). 

During the year to 31 December 2023, 500,000 ordinary shares were purchased by the Keller Group Employee Benefit Trust (2022: 135,050 purchased), 
to be used to satisfy future obligations of the company under the Keller Group plc Long-Term Incentive Plan and 515,119 shares were utilised to satisfy the 
obligation in the year (2022: nil). This brings the total ordinary shares held by the Employee Benefit Trust to 537,171 (2022: 552,290). The cost of the market 
purchases was £3.4m (2022: £1.2m). 

There is a dividend waiver in place for both shares held in treasury and by the Keller Group Employee Benefit Trust.

Capital commitments
Capital expenditure contracted for at the end of the reporting period but not yet incurred was £12.0m (2022: £17.6m) and relates to property, plant and 
equipment purchases.

31 Guarantees, contingent liabilities and contingent assets
Claims and disputes arise, both in the normal course of business and in relation to the historic construction activities of the Group, some of which lead to 
litigation or arbitration procedures. Such claims are predominantly covered by the Group’s insurance arrangements. The Group recognises provisions for 
liabilities when it is more likely than not that a settlement will be required and the value of such a payment can be reliably estimated.

At 31 December 2023, the Group had outstanding standby letters of credit and surety bonds for the Group’s captive and other global insurance 
arrangements totalling £24.5m (2022: £28.1m). The Group enters into performance and advance payment bonds and other undertakings in the ordinary 
course of business, using guarantee facilities with financial institutions to provide these bonds to customers. At 31 December 2023, the Group has £182.7m 
outstanding related to performance and advanced payment bonds (2022: £190.6m). These are treated as a contingent liability until such time it becomes 
probable that payment will be required under the individual terms of each arrangement. It is judged to be a remote possibility that a payment will be required 
under any of the current performance or advance payment bonds.

At 31 December 2023, the Group had no contingent assets (2022: £nil). 

32 Share-based payments
The Group operates a Long Term Incentive Plan (the ‘Plan’). Under the Plan, Executive Directors and certain members of senior management are granted 
nil-cost share options with a vesting period of three years. The awards are exercised automatically on vesting, in addition the Executive Directors are subject 
to a two-year post-vesting holding period. 

Performance share awards are granted to Executive Directors and key management personnel which are subject to performance conditions including 
total shareholder return, earnings per share, return on capital employed and operating profit margin. Conditional awards are granted under which senior 
management receive shares subject only to service conditions, ie the requirement for participants to remain in employment with the Group over the vesting 
period. Participants are entitled to receive dividend equivalents on these awards.

Outstanding awards are as follows:

Under IFRS 2, the fair value of services received in return for share awards granted is measured by reference to the fair value of share options granted. The 
estimate of the fair value of share awards granted is measured based on a stochastic model. The contractual life of the award is used as an input into this 
model, with expectations of early exercise being incorporated into the model.

The inputs into the stochastic model are as follows:

Expected volatility was determined by calculating the historical volatility of the Group’s share price over the previous three years, adjusted for any expected 
changes to future volatility due to publicly available information.

The Group recognised total expenses (included in operating costs) of £4.5m (2022: £2.9m) related to equity-settled, share-based payment transactions.

The weighted average fair value of options granted in the year was 555.7p (2022: 724.2p). Options outstanding at the year-end have a weighted average 
remaining contractual life of 1.2 years (2022: 1.2 years).

The awards, which are taken as shares, are intended to be satisfied from shares held under the Keller Group Employee Benefit Trust (the ‘Trust’) or from 
treasury shares held. The shares held by the Trust are accounted for as a deduction from equity in retained earnings. At 31 December 2023, 537,171 
(2022: 552,290) ordinary shares were held by the Trust with a value of £3.9m (2022: £4.9m). 

33 Retirement benefit liabilities
The Group operates pension schemes in the UK and overseas.

In the UK, the Group operates the Keller Group Pension Scheme (the ‘Scheme’), a defined benefit scheme, which has been closed to new members since 
1999 and was closed to all future benefit accrual with effect from 31 March 2006. Under the Scheme, employees are normally entitled to retirement benefits 
on attainment of a retirement age of 65. The Scheme is subject to UK pensions legislation which, inter alia, provides for the regulation of work-based 
pension schemes by The Pensions Regulator. The trustees are aware of and adhere to the Codes of Practice issued by The Pensions Regulator. The Scheme 
trustees currently comprise one member-nominated trustee and two employer-nominated trustees. An employer-nominated trustee is also the Chair of 
the trustees. The Scheme exposes the Group to actuarial risks, such as longevity risk, interest rate risk and market (investment) risk, which are managed 
through the investment strategy to acceptable levels established by the trustees. The Scheme can invest in a wide range of asset classes including equities, 
bonds, cash, property, alternatives (including private equity, commodities, hedge funds, infrastructure, currency, high yield debt and derivatives) and annuity 
policies. Any investment in derivative instruments is only made to contribute to a reduction in the overall level of risk in the portfolio or for the purposes 
of efficient portfolio management. With effect from the most recent actuarial valuation date (5 April 2023), the Group has agreed to pay a contribution 
of £1.7m in total, paid in monthly instalments from January to August 2024. Contributions will then cease, subject to a review of the level of employer 
contributions at the next actuarial review in 2026.

Between 1990 and 1997, the Scheme members accrued a Guaranteed Minimum Pension (GMP). This amount differed between men and women in 
accordance with the rules which were applicable at that time. On 26 October 2018, there was a court judgement (in the case of Lloyds Banking Group 
Pensions Trustees Limited v Lloyds Bank PLC) that confirmed that GMP is to be made equal for men and women. In 2018, the estimated increase in the 
Scheme’s liabilities was £1.3m, which was recognised as a past service cost in 2018 as a charge to non-underlying items. On 20 November 2020, there was 
an updated judgement requiring an allowance to be made for past transfers. The estimated increase in the Scheme’s liability in respect of this is less than 
£0.1m. These estimates remain appropriate for 2022. The actual cost may differ when the GMP equalisation exercise is complete.

A potentially landmark judgement was handed down in the High Court case of Virgin Media vs NTL Trustees in June 2023. The judge in this case ruled that, 
where benefit changes were made without a valid ‘section 37’ certificate from the scheme actuary, those changes could be considered void. It is anticipated 
that the ruling will be appealed. The Keller Group Pension Scheme was contracted out of the additional state pension between 1997 and 2016 and made 
scheme amendments during this period. The Scheme trustees have not yet investigated the scheme’s historic documentation to confirm whether they 
hold the relevant s37 certificates, until this review has been completed we are unable to determine the impact of this judgement.

The Group has two UK defined contribution retirement benefit schemes. There were no contributions outstanding in respect of these schemes at 
31 December 2023 (2022: £nil). The total UK defined contribution pension charge for the year was £1.8m (2022: £1.6m).

The Group has defined benefit retirement obligations in Germany and Austria. Under these schemes, employees are entitled to retirement benefits on 
attainment of a retirement age of 65, provided they have either five or ten years of employment with the Group, depending on the area or field they are 
working in. The amount of benefit payable depends on the grade of the employee and the number of years of service. Benefits under these schemes 
only apply to employees who joined the Group prior to 1997. These defined benefit retirement obligations are funded on the Group’s balance sheet and 
obligations are met as and when required by the Group.

The Group has a number of end of service schemes in the Middle East as required by local laws and regulations. The amount of benefit payable depends 
on the current salary of the employee and the number of years of service. These retirement obligations are funded on the Group’s balance sheet and 
obligations are met as and when required by the Group. 

The Group operates a defined contribution scheme for employees in North America, where the Group is required to match employee contributions up to a 
certain level in accordance with the scheme rules. The total North America pension charge for the year was £8.6m (2022: £8.1m).

In Australia, there is a defined contribution scheme where the Group is required to ensure that a prescribed level of superannuation support of an 
employee’s notional base earnings is made. This prescribed level of support is currently 11.0% (2022: 10.5%). The total Australian pension charge for the 
year was £4.8m (2022: £4.6m).

Included in this balance is £3.6m (2022: £3.5m) in relation to the end of service schemes in the Middle East.

For the Keller Group Pension Scheme, based on the net deficit of the Scheme as at 31 December 2023 and the committed payments under the Schedule 
of Contributions agreed on 15 December 2023, there is a irrecoverable surplus of £5.7m (2022: £7.3m). Management is of the view that, based on the 
Scheme rules, it does not have an unconditional right to a refund of a surplus under IFRIC 14, and therefore an additional balance sheet liability in respect of 
a ‘minimum funding requirement’ has been recognised. The minimum funding requirement is calculated using the agreed total remaining contribution of 
£1.5m, contributions will cease from August 2024. The contributions will be reviewed following the next actuarial review to be prepared as at 5 April 2026.

The value of the scheme liabilities has been determined by the actuary using the following assumptions:

Discount rate

Interest on assets

Rate of increase in pensions in payment

Rate of increase in pensions in deferment

Rate of inflation

A reduction in the discount rate of 0.5% would increase the deficit in the schemes by £2.6m (2022: reduction in the discount rate of 0.5% would increase 
the deficit in the scheme by £2.5m), whilst a reduction in the inflation assumption of 0.5%, including its impact on the revaluation in deferment and pension 
increases in payment, would decrease the deficit by £1.3m (2022: reduction in the inflation assumption of 0.5% would decrease the deficit by £1.3m).  
A decrease in the mortality rate by one year would decrease the deficit in the schemes by £1.8m. Note that these sensitivities do not include end of service 
schemes in the Middle East as these are not material to the Group. 

The weighted average duration of the defined benefit obligation is approximately 13 years for the UK scheme and 12 years for the German and Austrian 
schemes. The history of experience adjustments on scheme assets and liabilities for all the Group’s defined benefit pension schemes, including the end of

On 29 August 2023, the Group acquired the 35% interest in the voting shares of Keller Turki Company Limited, increasing its ownership interest to 100%.  
An initial cash consideration of £6.4m (SAR 30m) was paid to the non-controlling shareholders. In addition, a contingent consideration has been agreed as 
part of the purchase agreement and is payable annually between the years 2023 and 2027, dependent on the qualifying revenue generated by the business 
for each of those years. The fair value of the contingent consideration was £9.3m (SAR 43.2m) based on expected revenue generated by the business over 
that period, which is the maximum amount of contingent consideration payable.

On 1 March we announced a change to the Group’s divisional structure. The Middle East and NEOM business units will move from the current Asia-Pacific, 
Middle East and Africa (AMEA) division and combine with Europe to create a new Europe and Middle East Division (EME). The AMEA division will become the 
Asia-Pacific division. This is a non-adjusting post balance sheet event and there is no impact to the balance sheet at 31 December 2023. 

There were no other material post balance sheet events between the balance sheet date and the date of this report.

Notes to the company  

financial statements

Keller Group plc  Annual Report and Accounts 2023

Notes to the company financial statements

1 Principal accounting policies

Basis of preparation
The separate financial statements of the company are presented as required by the Companies Act 2006 (the ‘Act’). The company meets the definition of a 
qualifying entity under FRS 100 (‘Financial Reporting Standard 100’) issued by the Financial Reporting Council and reports under FRS 101.

Except as noted below, the company’s accounting policies are consistent with those described in the consolidated financial statements of Keller Group 
plc. As permitted by FRS 101, the company has taken advantage of the disclosure exemptions available under that standard in relation to share-based 
payments, financial instruments, capital management, presentation of a cash flow statement, related party transactions and comparative information. 
Where required, equivalent disclosures are given in the consolidated financial statements. In addition, disclosures in relation to share capital (note 28) and 
dividends (note 13) have not been repeated here as there are no differences to those provided in the consolidated financial statements.

These company financial statements have been prepared on the going concern basis and under the historical cost convention. The financial statements are 
presented in pounds sterling, which is the company’s functional currency, and all values are rounded to the nearest hundred thousand, expressed in millions 
to one decimal point, except when otherwise indicated.

Profit of the parent company
The company has taken advantage of section 408 of the Act and consequently the statement of comprehensive income (including the profit and loss 
account) of the parent company is not presented as part of these accounts. The profit after tax of the parent company for the financial year amounted to 
£95.7m (2022: £23.5m).

Amounts owed by subsidiary undertakings
The company holds inter-company loans with subsidiary undertakings with repayment dates being a mixture of repayable on demand or repayable on a 
fixed contractual date. These inter-company loans are disclosed on the face of the balance sheet. None are past due nor impaired. The carrying value of 
these loans approximates their fair value. The expected credit loss on these loans with subsidiary undertakings is expected to be immaterial, both on initial 
recognition and subsequently.

Financial instruments
Details of the company’s risk management processes and hedge accounting are included in the disclosures in note 26 to the consolidated financial 
statements.

Investments
Investments in subsidiaries are stated at cost less, where appropriate, provisions for impairment.

Audit fees
The company has taken the exemption granted under SI 2008/489 not to disclose non-audit fees paid to its auditors as these are disclosed in the 
consolidated financial statements.

Employees
The company has no employees other than the Directors. The remuneration of the Executive Directors is disclosed in the audited section of the 
Remuneration policy report on pages 135 to 142. Fees payable to Non-executive Directors totalled £0.5m (2022: £0.5m).

Financial guarantees
Where the company provides guarantees relating to bank borrowings and other liabilities of other Group companies, under IFRS 9 such contracts are initially 
recognised in the financial statements at fair value at the time the guarantee is issued. The company estimates the fair value of the financial guarantee 
as being the difference between the net present value of the contractual cash flows required under a debt instrument and the net present value of the 
contractual cash flows that would have been required without the guarantee. Subsequent to initial recognition, the company’s liability under each guarantee 
is measured at the higher of the amount initially recognised less the cumulative amount of income recognised in accordance with the principals of IFRS 15 
Revenue from Contracts with Customers and the loss allowance that would be recorded on the exposure. A financial guarantee liability is derecognised 
when the liability underlying the guarantee is discharged or cancelled or expires if the guarantees withdrawn or cancelled.

7 Contingent liabilities
The company and certain of its subsidiary undertakings have entered a number of guarantees in the ordinary course of business, the effects of which are 
to guarantee or cross-guarantee certain bank borrowings and other liabilities of other Group companies. At 31 December 2023, the company’s liability in 
respect of the guarantees against bank borrowings amounted to £nil (2022: £246.4m). In respect of one subsidiary, which is dormant and does not have the 
funds to pay its liabilities, the company has recognised a liability for the present value of the estimated cash shortfall that will arise if the subsidiary is wound 
up which is presented as other creditors in note 6. 

In addition, as set out in note 10, the company has provided a guarantee of certain subsidiaries’ liabilities to take the exemption from having to prepare 
individual accounts under section 394A and section 394C of the Companies Act 2006 and exemption from having their financial statements audited under 
sections 479A to 479C of the Companies Act 2006.

9 Pension liabilities
In the UK, the company participates in the Keller Group Pension Scheme (the ‘Scheme’), a defined benefit scheme, details of which are given in note 33 to 
the consolidated financial statements. The company’s share of the present value of the assets of the Scheme at the date of the last actuarial valuation on 
5 April 2023 was £13.1m and the actuarial valuation showed a funding level of 98%.

Details of the actuarial methods and assumptions, as well as steps taken to address the deficit in the Scheme, are given in note 33 to the consolidated financial 
statements. The policy for determining the allocation of each participating company’s pension liability is based on where each Scheme member was employed.

During 2022, the company was party to a flexible apportionment arrangement (FAA) to transfer in the portion of the scheme previously attributed to a 
dormant subsidiary entity. The Company previously accounted for a 14% share of the scheme assets and liabilities. During 2022, this then increased to 31% 
of the scheme assets and liabilities and in 2023 decreased to 29%.

In respect of Guaranteed Minimum Pension the estimated increase in the Scheme’s liabilities was £0.2m. This was recognised as a past service cost in 2018. 
An allowance has been made for an irrecoverable surplus of £1.7m (2022: £2.3m), representing the company’s allocation as a result of the Group not having 
an unconditional right to refund of a surplus under IFRIC 14. These items are explained further in note 33 to the consolidated financial statements. 

Details of the company’s share of the Scheme are as follows:

Present value of the Scheme liabilities

Present value of assets

Surplus in the Scheme

Irrecoverable surplus

Net defined benefit liability

Adjusted performance measures

Keller Group plc  Annual Report and Accounts 2023

215

Adjusted performance measures

The Group’s results as reported under International Financial Reporting Standards (IFRS) and presented in the consolidated financial statements (the 
‘statutory results’) are significantly impacted by movements in exchange rates relative to sterling, as well as by exceptional items and non-trading amounts 
relating to acquisitions.

As a result, adjusted performance measures have been used throughout the Annual Report and Accounts to describe the Group’s underlying performance. 
The Board and Executive Committee use these adjusted measures to assess the performance of the business because they consider them more 
representative of the underlying ongoing trading result and allow more meaningful comparison to prior year.

Underlying measures
The term ‘underlying’ excludes the impact of items which are exceptional by their size and/or are non-trading in nature, including amortisation of acquired 
intangible assets and other non-trading amounts relating to acquisitions and disposals (collectively ‘non-underlying items’), net of any associated tax. 
Underlying measures allow management and investors to compare performance without the potentially distorting effects of one-off items or non-
trading items. Non-underlying items are disclosed separately in the consolidated financial statements where it is necessary to do so to provide further 
understanding of the financial performance of the Group.

Constant currency measures
The constant currency basis (‘constant currency’) adjusts the comparative to exclude the impact of movements in exchange rates relative to sterling.  
This is achieved by retranslating the 2022 results of overseas operations into sterling at the 2023 average exchange rates.

A reconciliation between the underlying results and the reported statutory results is shown on the face of the consolidated income statement, with non-
underlying items detailed in note 9 to the consolidated financial statements. A reconciliation between the 2022 underlying result and the 2022 constant 
currency result is shown below and compared to the underlying 2023 performance:

Order book
The Group’s disclosure of its order book is aimed to provide insight into its backlog of work and future performance. The Group’s order book is not a 
measure of past performance and therefore cannot be derived from its consolidated financial statements. The Group’s order book comprises the 
unexecuted elements of orders on contracts that have been awarded. Where a contract is subject to variations, only secured variations are included 
in the reported order book.

Free cash flow
The calculation of free cash flow is set out in the CFO section of the Strategic report and is reconciled to movements in the consolidated cash flow 
statement and other movements in net debt as set out below.

Net cash inflow from operating activities

Net cash outflow from investing activities

Exclude:

Cash inflows from non-underlying items – contract dispute

Cash inflows from non-underlying items – ERP costs

Cash inflows from non-underlying items – restructuring costs

Cash inflows from non-underlying items – acquisition costs

Acquisition of subsidiaries, net of cash acquired

Disposal of subsidiaries

Include:

Increase in net debt from new leases

Increase in net debt from amortisation of deferred finance costs

Cautionary statement

Keller Group plc  Annual Report and Accounts 2023

This document contains certain forward-looking statements with 
respect to Keller’s financial condition, results of operations and business, 
and certain of Keller’s plans and objectives with respect to these items.

Forward-looking statements are sometimes, but not always, identified 
by their use of a date in the future or such words as ‘anticipates’, ‘aims’, 
‘due’, ‘will’, ‘could’, ‘may’, ‘should’, ‘expects’, ‘believes’, ‘intends’, ‘plans’, 
‘potential’, ‘reasonably possible’, ‘targets’, ‘goal’ or ‘estimates’. By their 
very nature forward-looking statements are inherently unpredictable, 
speculative and involve risk and uncertainty because they relate to 
events and depend on circumstances that may occur in the future.

There are a number of factors that could cause actual results and 
developments to differ materially from those expressed or implied by 
these forward-looking statements.

These factors include, but are not limited to, changes in the economies 
and markets in which the Group operates; changes in the regulatory 
and competition frameworks in which the Group operates; the impact 
of legal or other proceedings against or which affect the Group; 
and changes in interest and exchange rates. For a more detailed 
description of these risks, uncertainties and other factors, please 
see the risk management approach and principal risks section of the 
strategic report.

All written or verbal forward-looking statements, made in this document 
or made subsequently, which are attributable to Keller or any other 
member of the Group or persons acting on their behalf are expressly
