Chairman’s statement
Executing 
our strategy
We have seen another eventful year in 
the energy market with the invasion of 
Ukraine creating not only significant 
human suffering in that country, but 
also unprecedented turmoil and 
volatility in the price of energy. The 
impact on the cost of living has kept 
energy costs front and centre in the 
public’s mind. SMS has focused on the 
continuing and steady delivery of its 
strategy during this challenging period.
Performance
Despite the turbulence across the 
energy sector, we kept focused over 
2022 on delivering our strategic plan. 
The key priorities for the year were 
continuing to build our smart meter 
portfolio and proving that we could 
convert our grid-scale battery storage 
pipeline into profitable long-term 
assets. We made excellent progress 
in both these areas.
We continued to improve our smart 
meter installation run-rate installing 
480,000 over the year. This has led to 
our index-linked annualised recurring 
revenue growing 13% year-on-year. 
The smart meter roll out is scheduled 
to run to 2025 and we currently have 
 “Our results again demonstrate the resilience of our 
business model which is underpinned by recurring 
cash flows from long-term assets.”
Miriam Greenwood
Non-executive Chairman
a contracted smart meter order 
pipeline of a further c.2.17 million 
meters to install which will increase our 
long-term revenue-generating assets.
Our first grid-scale battery storage site 
at Burwell became operational in 
January 2022 and has performed 
ahead of our initial expectations. Our 
next two sites became operational in 
December, and we now have 140MW 
of battery storage assets generating 
revenue. We have also continued to 
build our grid-scale battery pipeline 
with our portfolio now standing at 
860MW at 28 February 2023.
We also continued to invest in 
developing our capabilities in electric 
vehicle charging and energy data 
management; areas where we can 
meet emerging market needs. We can 
see the continuing scope for growth in 
our established and developing CaRe 
asset classes reinforcing the long-term 
opportunity for the business.
Health, safety and 
sustainability
The safety and welfare of our people 
continues to be our first priority and I 
am pleased to say that we had zero 
reportable injuries for the second year 
running. You can read more about our 
work in these areas in our Sustainability 
section on pages 36 to 61.
Sustainability is at the heart of what we 
do at SMS, and our products and 
services have carbon reduction as their 
goal. We measure this as our ‘handprint’ 
– the amount of carbon emissions 
mitigated by our customers using our 
products and services. The positive 
impact of our 2022 handprint was 
63,495 tonnes of CO₂ emissions which 
06
SMS Annual report and accounts 2022

was 14.5 times the negative impact 
of our Scope 1 and Scope 2 carbon 
footprint (see page 50). 
We also made tangible progress over 
the year on our ‘net zero by 2030’ 
target for our business. We have been 
upgrading the fabric of our Cardiff site 
by installing solar panels and battery 
storage. When complete, we expect the 
improvements to reduce building 
emissions by 70%. We have also tested 
hybrid vans and will be commencing 
our fleet transition by introducing 100 
mild hybrid vans to the fleet in 2023.
Our people
At SMS we recognise that it is our 
people that deliver our achievements. 
We therefore place great emphasis on 
developing our employees and creating 
a positive and healthy workplace. Our 
commitment to developing and 
supporting our staff was recognised 
by us achieving Investors in People 
Silver accreditation, one of a number of 
initiatives we have delivered in this area. 
We are also conscious of our 
responsibility to provide our employees 
the security they need. We have been a 
‘Living Wage’ employer since 2020 and 
during 2022 also became an accredited 
‘Living Hours’ employer. To help our 
employees who may be experiencing 
pressure from the increased cost of 
living, we also made a one-off 
discretionary payment to most of our 
staff to help them through this winter 
and we brought forward implementation 
of 2023’s Living Wage increase.
Dividend
Two years ago, we set out our policy 
to grow our dividend by 10% each year 
through to 2024 and we are therefore, 
Principal decisions
On the pages listed in the table below we have provided examples 
of how the Board duly considered the impact on stakeholders when 
making principal decisions during 2022:
proposing a 30.25p per share dividend 
in respect of FY 2022. Two of the four 
equal quarterly instalments have 
already been paid, in October 2022 
and January 2023. We remain confident 
of the Group’s prospects and expect 
to maintain our dividend policy until 
2024 as stated.
Board changes
In October, we announced that Gavin 
Urwin was stepping down as Chief 
Financial Officer to take up another 
opportunity. The Board was pleased to 
appoint Gail Blain as Chief Financial 
Officer to take over from 1 December 
2022. Gail has been with the Group 
since 2016 in the role of Group Financial 
Controller. Over that time, she has 
worked closely with our Chief Executive 
Officer, Tim Mortlock, and has 
developed an in depth understanding 
of our business. She has played a key 
role in developing all areas of finance 
and in providing strategy support to 
the leadership team. Gavin is remaining 
available to the Group until 31 March 
2023 to ensure a smooth handover. 
On behalf of the Board, I would like to 
thank Gavin for his contribution to SMS 
and I wish him well in his future career.
Gail's appointment is further testament 
to our succession planning and ability 
to develop internal talent.
Governance
The Board remains committed to 
the highest standards of corporate 
governance. One feature of this 
governance has been the completion of 
our annual board self-evaluation process 
which this year has been facilitated with 
external input to support the Board in 
ensuring a rigorous review focused on 
continual improvement. 
SMS’s approach to stakeholder 
engagement is set out in more detail 
on pages 37 to 41 and our section 172 
statement is set out on page 37. 
The Annual report and accounts will 
enable stakeholders to assess how 
effectively the Board, supported by the 
executive leadership team and other 
employees, promoted the success of 
SMS during the year, specifically with 
respect to our obligations pursuant to 
section 172 of the Companies Act 2006. 
’Decision-making in practice’ case 
studies dispersed throughout the Annual 
report and accounts explain the principal 
decisions taken in the year and how the 
interests of relevant stakeholder groups 
were considered. A summary of these 
decisions is provided above. 
Looking to the future
The turbulence of the energy market 
in 2022 has focused attention on the 
global challenges of energy affordability, 
sustainability and security. I believe this 
attention has driven much wider 
recognition of the benefits that our 
carbon reduction assets, such as smart 
meters and grid-scale batteries, bring.
SMS will continue to meet this energy 
challenge and play its part in 
transitioning the UK to a more flexible 
and sustainable energy system and 
enabling the move to net zero. The 
Board therefore continues to focus on 
our established strategy, and under the 
strong leadership of our executive team 
we look to the future with confidence.

Chief Executive Officer’s statement
Delivering on our 
sustainable promises
 “Listening to customers is critical to our success 
in realising a greener, more sustainable future.”
Tim Mortlock
Chief Executive Officer
Never has the energy industry 
been more at the forefront of the 
national agenda than during 2022, 
with energy security, affordability 
and sustainability proving to be 
fundamental challenges affecting 
all of society. I am proud that SMS 
continues to respond to these 
challenges by delivering carbon 
reduction (‘CaRe’) assets and 
solutions which directly address 
each of them, both for our 
customers and end consumers.
Like many others, our company 
is increasingly judged not only on 
its financial performance, which 
has again been extremely strong 
in 2022, outperforming upgraded 
expectations (see more detail in the 
Financial review on page 70), but also 
on the contribution it makes to society. 
For us, sustainability isn’t just a 
headline. We see it as being at the 
heart of our purpose. We believe 
we have an obligation to serve our 
customers and to provide solutions 
which benefit all of society – but we 
can only do this if we continue to 
promote the wellbeing of our workforce 
alongside providing a secure long-term 
return for our shareholders. This starts 
by listening to our stakeholders, and 
over the last year there were two 
priorities for our business – delivering 
on our smart meter order pipeline 
and proving the returns on grid-scale 
batteries. We have operationally and 
financially delivered in both these 
critical areas in 2022, and I am confident 
this gives us the platform to grow 
recurring revenues within these core 
CaRe assets and beyond.
Smart meter delivery
We are delighted to have grown and 
delivered on our smart meter order 
pipeline over the last year. We built 
our smart meter installation run rate 
to c.45,000 per month in the second 
half of the year, and installed c.480,000 
meters over the course of the year 
exceeding our target of 450,000 – 
c.12% of all new smart meters in the UK 
(2021: 9.4%). This resulted in an increase 
in our index-linked annualised recurring 
revenue (ILARR) from metering and 
data assets to £97.1m at year end.
This success followed continued 
investment in our engineering capacity, 
particularly in the latter part of 2021 
and first half of 2022, which we have 
been able to support due to the 
long-term security of the recurring 
revenues that flow from these assets, 
and the strength of our continued 
order pipeline.

Chief Executive Officer’s statement continued
At the year end this pipeline, net of 
installations, stood at c.2.17 million. With 
annual binding installation targets on 
energy suppliers through to the end of 
2025 to deliver the smart meter rollout, 
we will continue to incrementally invest 
in our engineering capacity and supply 
chain to deliver this critical infrastructure. 
The index-linked nature of our revenues 
also ensures we have significant 
protection from the current inflationary 
environment. Our continued investment 
in our supply chain, our meter stock and 
the efficiency of our delivery model 
together with this index linkage ensures 
that, despite the impact of inflation, 
the returns on our incremental capital 
investment in meters will remain at least 
in line with our previous guidance. In this 
way, returns from the pipeline are 
secured – further reinforcing the 
defensive nature of the asset class.
I believe that 2022 also saw a sea 
change in the public understanding 
of and support for smart metering – 
end consumers now demanding smart 
meters to allow better visibility and 
control over their consumption and 
energy costs. At the same time, recent 
threats to our energy security have 
only increased the need to manage 
consumption, particularly at peak 
periods or when renewable generation 
is low. National Grid’s introduction of 
its ‘Demand Flexibility Service’ (DFS), 
which pays people with smart meters 
to use less energy at times of stress 
on the network, is just the start of this 
long-term drive to gain flexibility from 
using data. You can read more about 
the DFS scheme and how we are 
enabling energy suppliers to 
participate on page 26.
Batteries are critical to 
energy security and net zero
We have been talking to our 
stakeholders for several years about 
how energy storage is critical to the 
long-term security and sustainability 
of our energy system. We are therefore 
delighted that our first 50MW project 
went live in January 2022 and that we 
ended the year with a total of 140MW 
of operational grid-scale battery 
storage capacity. A significant highlight 
of the year has been proving that this 
asset class can help integrate 
intermittent renewable generation to 
the energy network and can generate 
attractive long-term revenues.
Similar to the change in the public’s 
perception of smart meters, events 
in 2022 have driven a greater 
understanding of the long-term need 
for grid-scale battery storage. The 
war in Ukraine exacerbated concern 
about the security of our energy supply 
and in its July Future Energy Scenarios 
report, National Grid increased its 
forecast requirement for grid-scale 
battery storage by c.5.8GW to c.14.1GW 
by 2030.
Having the capability to rapidly 
develop, build and operate these 
projects – particularly in the face of grid 
connection constraints – to address this 
market need is clearly vital, and for that 
reason I am delighted that we continued 
to grow our portfolio of projects during 
2022 to 760MW at 31 December 2022. 
Since then, we have added a further 
two 50MW projects under exclusivity 
bringing the portfolio to 860MW. Within 
that portfolio, 610MW has now been 
fully secured and is either operational 
or ‘shovel-ready’.
We have demonstrated our capability 
to develop and deliver on this pipeline 
within our capex guidance, but of equal 
importance was that in 2022 we proved 
the return on investment. We were 
delighted therefore that we delivered 
revenues significantly ahead of our 
previous expectations, equivalent to 
an annualised c.£123,000 of EBITDA 
per MW. The majority of the revenues 
were generated from the provision of 
frequency services, and whilst we 
expect those to soften over time, there 
is a parallel and long-term requirement 
to provide balancing services to the 
national energy network. This will 
enable a smarter and lower-carbon 
energy system, reducing peak energy 
costs and underpinning national 
energy security.
I was delighted to host an investor site 
visit to our first 50MW operational site 
at Burwell in October, which you can 
read about on page 38.
Serving our customers
Listening to and serving our customers 
remains at the heart of our purpose – 
and this means delivering operational 
excellence every single day. This starts 
with health and safety where I am 
pleased to say we have again shown 
industry-leading performance across 
our key performance measures:
•	 zero reportable injuries or dangerous 
occurrences (RIDDOR incidents)
•	 maintained industry-leading 
performance on Lost Time, Non-Lost 
Time and Total Recordable Incident 
Frequency Rates
•	 continued improvement, and ahead 
of target, in group technical 
performance
•	 no significant incidents at our growing 
portfolio of grid-scale battery sites
We have also continued to focus 
on our Net Promoter Score (NPS), 
performance against industry 
guaranteed standards and customer 
complaints, all of which have again 
shown continual improvement and 
are ahead of target. 
10
SMS Annual report and accounts 2022

The efficiency of our operations is 
also clearly important. We grew our 
engineering and installation capacity 
early in the year while keeping job 
completions per engineer in line 
with our expectations. 
You can read more about our 
operational performance on 
pages 32 to 35.
CaRe growth
2022 demonstrated the continued 
security and stability of our business 
model and that we can execute on our 
strategic growth plan. Delivering our 
existing smart meter and grid-scale 
battery pipelines alone will more than 
double the EBITDA of our business, 
before taking into account the net 
positive impact of inflation on our 
index-linked recurring revenues.
However, the most exciting part of our 
business is the further opportunity to 
grow beyond these contracted and 
secured pipelines. I have already 
referred to the expected grid-scale 
battery storage market size by 2030, 
but in addition to this, smart meters are 
enabling a more dynamic, digital and 
flexible smart energy system to be built 
– which we will need if we are to resolve 
the significant security, affordability 
and carbon challenges we face.
The National Grid DFS service points to 
a future where half-hourly smart meter 
consumption data is central to the 
control, management and aggregation 
of behind-the-meter solutions, such as 
local solar and storage, and to controlling 
increasing peak demand from the 
electrification of transportation and 
heat. Our technology platforms can 
facilitate this new energy system, by 
delivering on mandatory half-hourly 
settlement for energy suppliers whilst 
optimising the use of energy to balance 
the energy grid and respond to price 
signals – just like we do at the grid-
scale level.
Bringing together this technology and 
our energy knowledge and engineering 
capacity enables us to develop our 
asset deployment capability in wider 
CaRe solutions. For example, we can 
originate, own and operate electric
vehicle charging infrastructure and in 
some cases link this to local generation 
and storage to optimise the cost and 
use of energy. These solutions are 
closely aligned to our existing skills and 
capabilities, and again address the key 
challenges of our time. 
The technical solutions to address 
these themes of security, affordability 
and sustainability already exist and 
that is why I feel that at SMS we have 
an obligation to use our platform to 
deliver these emerging solutions, 
support the path to net zero and 
reduce energy costs for end 
consumers. In doing so we will also 
continue to securely grow our business, 
our asset base and our returns for the 
benefit of all our stakeholders.
Our people
Our values underpin our entire business, 
and nowhere is this more apparent 
than in our greatest asset – our people. 
You can read more about the significant 
effort we have made into ‘Putting our 
people first’ on pages 51 to 55, but the 
highlight for me is being able, post-
pandemic, to see first-hand the pride 
our staff take in delivering our services 
across the country. 
I was also pleased in October to launch, 
with the Rt Hon Justine Greening, our 
‘Levelling Up Impact Report’ setting 
out our commitment, in partnership 
with the Purpose Coalition, to levelling 
up through the framework of the 
Levelling Up Goals. 
Sustainability underpins everything we 
do at SMS. This means not just doing 
what we can to help our environment; it 
also means building a long-term secure 
business for all our stakeholders, and 
contributing to the prosperity of people 
and society in general. We aim to 
achieve this positive impact through 
responsible corporate governance, as 
much as through the direct and indirect 
effects of our innovative energy 
solutions. That means promoting 
policies that prioritise wellbeing, open 
recruitment, and fair career progression, 
as well as nurturing a truly diverse and 
inclusive workforce.
Looking forward
Our focus remains on executing 
our strategic growth plan over the 
coming year:
•	 installing c.600,000 smart meters 
to continue to build our ILARR;
•	 building out our secured pipeline 
of grid-scale battery projects and 
continuing to evidence the returns 
at least in line with our updated 
guidance;
•	 growing these smart meter and 
grid-scale battery pipelines further;
•	 building the opportunity pipeline in 
wider CaRe assets, such as EV 
charging infrastructure and behind-
the-meter solutions such as solar 
and storage; and
•	 leveraging our technology platforms 
to enable a smart, data-driven, 
energy system.
We have consistently demonstrated 
our ability to fund and deliver on this 
growth agenda and we believe that 
the opportunity ahead of us in terms 
of market size is very significant. It is 
incumbent on us to deliver on those 
opportunities for the benefit of all our 
stakeholders. 
I would once again like to thank all our 
staff, leadership team and Board, who 
continue to work passionately to help 
deliver our purpose – it is a privilege 
to lead an organisation with such a 
committed workforce. My thanks also 
to all our customers for their continued 
support and partnership.
I am proud of what we have delivered 
this year and excited by the enormous 
potential we can achieve in the years 
ahead.

Market overview
The changing energy 
landscape
The net zero 2050 legislation underpins the critical 
energy transformation happening in the UK today. 
It is clear that increasing intermittent renewable generation will 
have a fundamental impact on the future of our energy networks. 
Furthermore, in addition to this transition to sustainable generation, 
ongoing geopolitical tensions have reinforced the need to deliver 
this change in a way that also addresses both energy security and 
the cost-of-energy crisis.
The energy landscape is therefore dominated by the need to create 
an equilibrium between decarbonisation, energy security and the 
cost of energy – and to do so requires significant investments in 
technologies and assets which provide flexibility and resilience to 
the energy system. 
Over the last decade, the UK has been transitioning away from 
a system of centralised and highly predictable generation to one 
dominated by distributed intermittent renewable generation. 
However, given that renewable generation is neither forecastable 
nor controllable, this unpredictability is impacting the grid and also 
making the energy system less reliable at a time when we see the 
potential for increasing peak demand driven by the electrification 
of heat and transport. The increasing multi-directional flow of energy 
and information increases volatility further.
This is where SMS’s carbon reduction 
(‘CaRe’) assets are meeting the 
energy challenge. Smart meters 
continue to be key to enabling more 
efficient energy use, and the data 
they provide can facilitate building 
a more flexible energy system that 
makes it easier to match energy 
supply and demand. There is a 
mandated national target for an 
85% rollout by 2025.
Whilst grid-scale energy storage 
is needed to absorb excess energy 
generation, demand-side flexible 
systems, like distributed solar and 
storage, air-sourced heat pumps 
and electric vehicle charging 
infrastructure not only deliver 
low-carbon solutions to our energy 
needs but also provide the ability to 
power down non-essential equipment 
at times of high system load or 
power up standby generation 
when grid prices peak.
Ultimately, transitioning towards a 
cheaper, cleaner, and more secure 
renewable energy future requires 
local renewable sources of energy 
and efficient ways to manage how 
and when that energy is used.

Market overview continued
Our market position
Smart meters and data 
The UK Government has mandated 
that energy suppliers replace 
traditional meters with smart meters 
and has set an objective of achieving 
85% coverage by the end of 2025. The 
significant increase in energy prices 
and the increasing understanding of 
the benefits to consumers supported 
strong demand for smart meters in 
2022 - with smart meters installed 
across the industry, the highest since 
the rollout began.
There are now c.30 million smart 
meters installed across the UK 
(including 2.1 million owned by SMS) 
with c.26 million traditional meters 
still to be exchanged for smart ones 
by the end of the roll-out period. With 
our full end-to-end capabilities, SMS 
is perfectly positioned to capitalise 
on this opportunity. We have a 
c.2.17 million contracted smart 
meter order pipeline and we are 
currently installing c.12% of all new 
smart meters in the UK.
The UK Government has also confirmed 
its intention to mandate market-wide 
half-hourly settlement from 2026, which 
will require the balancing of the electricity 
industry on an actual half-hourly 
consumption basis rather than an 
assumed energy usage profile. This 
settlements service provides a 
significant opportunity for SMS and 
new solutions will also then be enabled 
- using smart meter data to drive more 
efficient use of energy and save 
customers money. This will grow the 
current market from c.480,000 Industrial 
& Commercial (I&C) electricity metering 
points (in which we have c.10% market 
share) to c.32 million I&C and domestic 
meters. One of the first of these data 
driven solutions is The Demand 
Flexibility Service (see page 26).
Grid-scale energy storage
The UK’s energy storage capacity 
is projected to grow from c.4GW at 
31 December 2022 to 38GW by 2050, 
with 26.2GW expected to come 
from batteries. 
With 25 years’ experience delivering 
large-scale electrical infrastructure 
across the country, SMS remains 
unique in its approach to grid-scale 
storage, by covering the majority of 
the value chain in-house. Our specialist 
in-house teams manage the design, 
supply, installation, operation, 
maintenance and energy trading of 
our battery energy storage sites. At 
31 December 2022 we had a 760MW 
portfolio of projects (of which 610MW 
is either commissioned, under 
construction or fully secured, with the 
remaining under exclusivity) and our 
target is to deliver 1.5GW by 2030; 
this will provide us with a c.10% 
market share.

Electric vehicle charging
The UK Government has announced 
that sales of all new petrol and diesel 
cars and vans will end in 2030 and 
plans to introduce percentage targets 
for sales of clean vehicles from 2024. 
To support this transition, the UK 
Government expects around 480,000 
public chargers will be required as a 
minimum by 2030 (of which there are 
currently just 36,750 installed nationally 
as of December 2022). This figure does 
not include the potential number of 
chargepoints in domestic and private 
commercial premises in the UK.
SMS has EV charging solutions 
targeting both public and domestic 
chargepoints. We offer a fully end-to-
end integrated platform for EV 
charging infrastructure to the non-
domestic market – installing, owning 
and operating car charging networks 
offering a full life cycle proposition, 
from initial consultancy and design 
of electrical infrastructure, through to 
technology procurement, installation, 
and ongoing ownership, operation and 
maintenance of the assets. In addition 
to workplace and public charging, 
SMS is also targeting the destination 
charging market – which broadly refers 
to chargepoints installed at leisure, 
retail, and hospitality businesses – 
as well as the fleet sector.
SMS has also begun to install domestic 
EV chargepoints, an engineering 
competency closely aligned to our 
existing delivery resource, and we are 
developing asset-owning commercial 
models to extend our CaRe business 
model in this substantial market space.
Distributed (‘behind-the-
meter’) energy resources
FlexiGrid
FlexiGrid is a cloud-based software 
platform that monitors and controls 
a range of distributed energy resources 
(DERs) such as solar panels, home 
batteries, electric vehicle chargepoints 
and smart heating systems. FlexiGrid 
operates these as a virtual power plant 
(VPP) and delivers the real-time 
flexibility essential for a decarbonised 
system. This brings a whole host of 
commercial, operational, and 
environmental advantages including 
balancing renewable generation 
locally, managing local grid constraints, 
reducing the cost to deliver electricity 
and enabling the supply of cheaper, 
cleaner renewable energy.
Solopower
Our ‘Solopower’ proposition offers 
local housing authorities a funded solar 
generation, smart battery storage and 
air-sourced heat pump solution that 
addresses the dual challenge of carbon 
emissions and fuel poverty. 
We partner with social housing 
providers to upgrade the energy 
performance of social accommodation 
and their residents at zero upfront cost 
- Solopower can decarbonise housing 
electricity by approximately 70% per 
home, whilst reducing tenant electricity 
bills by up to 28%. 
The financing and delivery of clean 
technology across the UK housing 
stock will be essential for meeting the 
Government’s Net Zero 2050 target 
and alleviating fuel poverty amidst 
a cost-of-living crisis. The funded 
solution will offer the social housing 
sector – which accounts for 
approximately five million UK homes – 
an opportunity to meet its carbon 
reduction and fuel poverty objectives.

Operating review
Delivering growth
During 2022, our operational focus was on further 
growing our pipeline of smart meters and grid-scale 
batteries and delivering against our existing secured 
pipelines of asset deployment, most notably across 
both smart meters and grid-scale batteries. At the 
same time, we maintained our unrelenting commitment 
to safety and customer service. 
Whilst no business is immune to 
inflationary cost pressures, the 
index-linked nature of our metering 
and data revenues and the efficiency 
of our delivery model have continued 
to ensure we manage the capital cost 
of originating these assets at least in 
line with our guided expectations.
•	 50% increase in our smart meter 
installation run rate (H2 2022 
v H2 2021)
•	 13% increase in our ILARR
•	 Over 110% increase in our fully 
secured grid-scale battery portfolio
•	 140MW grid scale batteries now 
operational; generating 
annualised EBITDA performance 
of £123,000/MW.
We were pleased during 2022 to add 
a further 100,000 meters to our 
contracted smart meter order pipeline 
which ended the year at c.2.17 million, 
while our deployed smart meter 
portfolio increased to 2.1 million as a 
result of installing over 480,000 smart 
meters during the year. This, alongside 
an inflation increase, drove our ILARR 
to end the year at £97.1m. It is worth 
reiterating that these are the 
annualised index-linked recurring 
revenues which flow from our deployed 
meter and data assets.
Our smart meter installation run rate 
increased to c.45,000 per month in the 
second half of the year and we are now 
installing c.14% of all smart meters across 
the UK. We invested substantially in our 
workforce, particularly in our direct 
labour, in the first half of the year but 
continue to manage an efficient balance 
between direct and sub-contract labour. 
We expect to continue to increase our 
smart meter installation run rate in 2023 
as we seek to deliver on energy suppliers’ 
mandated requirement for 85% of all 
meters to be smart by the end of 2025.
We were also pleased to continue to 
grow our overall portfolio of grid-scale 
battery projects to 760MW at year end 
(31 December 2021: 620MW), and since 
then by a further two 50MW projects 
under exclusivity to 860MW. Of 
particular note, we increased the fully 
secured and ‘shovel-ready’ proportion 
of this portfolio to 610MW (2021: 
290MW). Within this overall portfolio 
we were delighted to energise and 
bring 140MW into commercial 
operation during the year, with a further 
150MW in advanced construction.

Asset management
The UK smart meter rollout continues 
to present a significant opportunity 
for us to grow our ILARR, with Ofgem 
continuing to place annual binding 
installation targets on energy suppliers 
to ensure at least 85% of all meters are 
changed to smart by the end of 2025.
Our industry-accredited services, built 
on our in-house technology platform 
METIS and national engineering 
infrastructure, provide a strong basis 
from which to efficiently deliver these 
asset and data solutions to our 
customers. The industry structure 
underpinning these accreditations is 
evolving as a result of smart meter 
deployment and is set to enable all 
industry participants, and ultimately 
end consumers, to benefit from the 
consumption data available from them 
and the increasing digitisation of the 
energy system.
We therefore continue to invest in our 
METIS platform, not only to meet the 
requirements of this industry change 
but also to address the mandated 
settlement of energy on a half-hourly 
basis from 2026, which will significantly 
increase the market size for these 
services from c.480,000 electricity 
meters to over 32 million meters by 2026.
However, this increasing opportunity 
for data services is not just about 
industry settlement processes– it is 
about enabling end consumers of 
energy to benefit by controlling and 
aggregating the use and generation 
of energy at different times of day in 
response to the needs of the grid. Our 
technology platforms are already 
beginning to address this long-term 
and growing market need. Through 
these assets and data services, we 
continue to enable the transition to 
a low-carbon energy system for a 
greener, more sustainable future for all.
2022 performance
ILARR: During 2022 we increased our 
meter and data ILARR from £85.9m 
to £97.1m, due largely to the application 
of a 4.3% RPI increase in April 
alongside the addition of 480,000 
meters to our smart meter portfolio 
- we now own 2.1 million smart meters. 
The ILARR from this domestic smart 
meter portfolio increased from £50.1m 
to £61.0m, with this growth offset by 
the expected and continued removal 
of traditional meters. Our data 
services ILARR increased from 
£13.9m to £16.0m.
Pipeline: During 2022 we added a 
contract for a further 100,000 meters 
to our pipeline, which therefore 
increased on a like-for-like basis to 
2.65 million meters. Following the 
installation of c.480,000 meters 
during the year we exited with a 
contracted smart meter order pipeline 
of c.2.17 million meters, which once 
installed is expected to add a further 
c.£48m to our ILARR, excluding the 
annual indexation also applied on our 
pipeline. We continue to see additional 
opportunities to grow this pipeline 
further, particularly through the 
extension of minimum contracted 
volume commitments with existing 
customers where their customer 
base grows as a result of the market 
turbulence over the last year.
Our smart meter rentals are index-linked and 
not related to the amount of energy consumed 
or wholesale energy prices. They therefore 
provide a highly defensive, predictable and 
secure infrastructure asset class.

We are also developing wider 
commercial subscription models for the 
ownership and rental of other behind-
the-meter assets to end-consumers 
and landlords such as domestic EV 
chargers, solar, storage and air-
sourced heat pumps. We are seeking 
to partner with our existing and new 
customers to offer these broader 
CaRe services to end consumers.
SMETS1 Enrolment & Adoption: 
The enrolment and adoption of 
first-generation (‘SMETS1’) smart 
meters into the Data Communications 
Company (DCC) continued to accelerate 
through 2022, with now c.65%, SMETS1 
meters migrated to the DCC platform. 
This effectively enables them to remain 
smart regardless of who the energy 
supplier is and operate like a SMETS2 
meter. The migration of our SMETS1 
portfolio has progressed marginally 
ahead of this industry progress, with 
now c.80% of our relevant meters 
transferred. This process has now been 
extended through to the end of 2023.
Delivery: Following from previous 
Brexit and COVID-19 concerns, SMS 
made conscious decisions through 
2021 and 2022 to further diversify 
its supply chain (to four meter 
manufacturing partners), to fix the 
cost in sterling of a significant 
proportion of our forward meter 
purchases and to increase the level 
of buffer stock we hold in our UK 
warehouses. Whilst not without 
some impact on working capital, 
these decisions have proven prescient. 
They have ensured that we minimise 
the impact of inflationary increases 
on our meter installation and have 
ensured that stock availability has 
not been an impediment to delivering 
or growing our meter pipeline. 
This successful management of our 
hardware supply chain has gone hand 
in hand with the continued efficiency 
of our operational delivery, ensuring 
we have the capacity to deliver on 
our contracted pipeline and take 
advantage of further opportunities in 
the market. At the same time, we have 
continued to deliver on our return 
expectations by ensuring that the 
capital cost per meter installation 
increases by less than the indexation 
applied to our rentals.
Decision-making in practice: acquisition 
of n3rgy data platform
SMS has been providing half-hourly data services, largely to the Industrial & 
Commercial market, from both electricity and gas meters for nearly two 
decades. This part of our business grew further in 2021 following the 
acquisition of a ‘large-power’ metering and data portfolio from a large 
energy supplier. In this market space our data services include collection 
of consumption data directly from the meter, which we then provide to 
energy suppliers and end users for energy management, billing and 
industry settlements purposes.
The regulator has mandated the similar settlement of energy on a half-
hourly basis across all smart metered supply points from 2026, 
significantly increasing the market size from c.480,000 electricity meters 
to over 32 million meters. However, collection of the consumption data 
for these smart meters is undertaken by the DCC.
During 2022 we therefore worked closely with, and ultimately acquired, 
n3rgy – a digital technology platform which enables and facilitates the 
use of energy consumption, generation and tariff data from smart meters 
on the DCC platform. 
The acquisition, for an initial case consideration of £1.4m, means that SMS 
can effectively, with consumer permission, access half-hourly consumption 
data directly from smart meters, therefore enabling us to offer turnkey 
settlement services to domestic energy suppliers just like we already do 
in the I&C market. The acquisition, together with the Group’s accredited 
and scalable technology platforms, will enhance and accelerate SMS’s 
capabilities in smart energy data solutions, providing the Group with a 
strong competitive position in the significant addressable market as the 
industry moves towards mandatory half-hourly settlement. As a platform 
for growth, and akin to accelerated IT capex, the Board judged the 
acquisition to be in the long-term interest of shareholders.
n3rgy also expands the range of data services we are able to provide, for 
example by enabling third parties and end consumers to have direct access 
to their energy usage data and costs, facilitating the management of this 
usage and enabling them to participate in the energy market in new ways. 
For instance, we are already using this capability to enable end consumers 
to be paid to use less energy at times of stress on the energy network, 
through National Grid’s Demand Flexibility Service (see page 26).
Before approving the transaction, the Board reviewed papers and 
challenged management on the business cases, the risks and opportunities 
presented by the deal and the continued investment in the platform 
required. The Board took specific cognisance of the alternative third-party 
routes to obtaining this capability versus such an in-house approach, and 
the potential timescale and cost of developing the capability internally.
Customers – the Board noted that the transaction provided opportunities 
to expand our data services offering and relationships with domestic energy 
suppliers and to facilitate the positioning of our business for both mandatory 
half-hourly settlement and the developing data-driven smart energy grid.
Employees – two employees joined the Group as part of the transaction, 
with third-party development, support and maintenance arrangements put 
in place prior to completing the transaction to ensure our continued ability 
to service and grow the platform. An additional £0.8m of contingent 
consideration will be payable by SMS subject to n3rgy achieving certain 
performance targets.

Demand Flexibility Service – enabling a smarter grid
The Demand Flexibility Service (DFS) 
has been developed to allow the 
Electricity System Operator (National 
Grid ESO) to access additional 
flexibility when the national power 
demand is at its highest – typically 
during peak winter days. 
It is an additional tool that the ESO 
can use to keep the lights on this 
winter and has been designed to 
reduce pressure on the grid by 
providing an incentive for customers 
to either reduce consumption or shift 
it to different time periods.
Through two core SMS capabilities, 
collecting smart meter energy data 
via n3rgy and using our flexibility 
aggregation platform, FlexiGrid, we 
have been supporting energy suppliers 
and other businesses offering DFS to 
domestic consumers this winter.
As an Approved Provider of DFS 
to National Grid ESO, SMS performs 
a service whereby end-consumers 
are notified, via our partners, of an 
upcoming DFS event up to 24-hours 
before the event takes place. If a 
consumer decides to opt-in and 
participate in the event, SMS 
calculates the actual demand 
reduction during the event period, 
relative to their baseline consumption 
in the same period, by using FlexiGrid 
to automatically poll data from their 
smart meters via the n3rgy DCC 
adapter. SMS then sends individual 
demand reduction figures, for every 
MPAN that participated in the event, 
to their partners so that incentives, 
monetary or otherwise, can be 
passed on to their end-customers. 
Overall reduction values are 
simultaneously sent to National 
Grid ESO, who pay Approved 
Providers per MWh of demand 
reduction during the period.
SMS launched the service in 
December 2022 and, as of 
31 January 2023, had been 
responsible for over 30 MWh of 
demand reduction across six events 
with our partners, smart meter app 
providers Trust Power (Loop) and 
Hugo Energy. SMS processed data 
for over 14,000 MPANs in National 
Grid ESO’s second ‘Live’ event on 
24 January 2023. SMS expects 
end-customer numbers to increase 
significantly by the end of March, 
when this service period comes to 
an end, due to the onboarding of a 
major energy supplier to the service.
Through participation in this essential 
new service, SMS is helping National 
Grid, energy suppliers, technology 
companies and end-consumers to 
simultaneously address the combined 
challenges of energy security, 
affordability and sustainability. 
It is also an indication of what can 
be achieved if time-of-use tariffs 
and incentives are widely adopted 
and implemented by industry. 
Furthermore, using FlexiGrid’s existing 
capabilities, the entire process can be 
automated by controlling and 
aggregating behind-the-meter 
flexibility assets to import and export 
energy in response to the needs of the 
grid. Given its existing capabilities, 
SMS is extremely well positioned to 
become a data leader in this space, 
working on a B2B2C basis with a wide 
pool of energy industry stakeholders.

Asset installation
This resource is supported by our 
in-house accredited training academy, 
which we see as central to promoting 
health and safety (H&S) and compliance 
standards across our business, and our 
ability to train this engineering capability 
to extend it into new sectors – such as 
the installation of domestic electric 
vehicle charging infrastructure.
We also continue to work with developers 
for new connections utility infrastructure 
and metering, and are accredited to 
provide services across all market 
segments – partnering with energy 
suppliers, businesses and public sector 
organisations to deliver the transition 
to net zero. A continued and critical 
feature of our business is the emergency 
call out and maintenance services we 
provide to ensure continuity of supply 
to end consumers.
2022 performance
Whilst the Omicron variant of COVID-19 
continued to present some challenges, 
in Q1 in particular, we continued to 
abide by amended working practices 
and the related PPE and doorstep 
protocols where appropriate. However, 
we were largely able to focus on scaling 
up our installation activities over the 
course of the year.
The health and wellbeing of all our 
stakeholders comes first however, and 
again we reported zero injuries under 
the Reporting of Injuries, Diseases and 
Dangerous Occurrences Regulations 
2013 (RIDDOR) and also maintained 
industry-leading performance on our 
other key metrics, including technical 
quality incidents from our robust 
auditing regime which was at 15 
incidents per 100,000 installations. 
	 See our Health and safety section 
on pages 56 to 59 for more details.
Beyond H&S, we measure our success 
across three sets of KPIs: Quality; 
Quantity; Efficiency.
Quality:
Helping consumers use less energy 
has never been more important. We 
refreshed the knowledge of our field 
engineers so that they could better 
tailor energy efficiency advice to each 
customer, and we supported this with 
a new range of leave behind materials 
and by sending each customer a digital 
link to free energy efficiency advice on 
our website. We are collaborating with 
the Retail Energy Code so that we 
continue to make our consumer 
conversations more valuable.
In the second half of the year emergency 
call-outs were much higher than normal. 
The flexibility provided by our direct 
and sub-contract workforce however 
allowed us to minimise disruption 
and maintain our general standards 
of service.
We ended 2022 with a net promoter 
score of +34.1 based on nearly 8,000 
reviews on Trustpilot, and we increased 
our Trustpilot rating to 4.1 stars. The 
level of upheld complaints was also 
low at 0.13% of the total number of jobs.
Quantity:
During the year we were pleased to 
increase our installation run rate as 
planned to over 45,000 meters per 
month in H2 (H2 2021: 30,000 meters 
per month). This means that we are 
now installing c.14% of all smart meters 
across the UK (2021: 9.4%). The industry 
as a whole has deployed 30.3 million 
smart meters to date, with 26.2 million 
left to be deployed – of which 17.7 million 
need to be installed by the end of 2025 
to meet the Government’s 85% 
completion target. 
Our vertically integrated model remains 
key to our success, and the growth in 
our run rates came as a result of 
continued investment in our engineering 
capacity, particularly in our direct 
labour, in the first half of the year. 
As a result of these investments, we 
successfully increased the run rate and 
installed 480,000 smart meters during 
the year but continued to maintain an 
efficient balance between direct and 
sub-contract labour. We expect to 
continue to increase our smart meter 
installation run rate in 2023 as we 
deliver on energy suppliers’ mandated 
requirement for the roll out.
We will continue to invest incrementally 
in our engineering capacity, and we 
expect to install c.600,000 smart 
meters in 2023.
We continued to grow our nationwide engineering services 
business during 2022, with our in-house engineering labour force 
increasing by c.50% from c.330 engineers to c.470 engineers 
over the last year. Alongside this internal engineering resource, 
we continue to be supported by a wider supply chain such that 
we have over 600 engineers in total delivering our smart and 
advanced metering services across the country.

Efficiency:
With a balanced approach to direct 
and sub-contract labour, we are 
continually focused on the efficiency 
of our delivery, primarily measured 
through:
•	 the number of completed jobs 
per day per engineer
•	 the cost per job
•	 the number of engineering 
available days
By close control of these measures 
and of our back-office activities, and 
with the commitment of our dedicated 
workforce, we have been pleased to 
contain the inflationary increase in 
the installation cost per meter in line 
with the indexation we applied to 
our rentals. Alongside our asset 
management division’s management 
of hardware costs, this ensures we at 
least maintain our expected returns 
on capital, and has ensured we 
maintain strong gross margins on 
our transactional installation services.
Confident in our 
continued delivery
We will continue to invest in and grow 
our delivery capacity incrementally 
to ensure delivery of our CaRe pipeline 
over the coming year, particularly in 
smart meters, and we are confident 
in our ability to grow the run rate and 
efficiency of our operation.
To support this, we have embarked on 
a refresh of our asset deployment 
technology platforms, with the aim of 
continually improving their integration 
into our asset management and ERP 
systems. By doing this we will continue 
to improve and digitise the customer 
experience, and further automate the 
validation and transfer of data 
between these systems – ensuring 
continued efficiency not only in our 
delivery of smart meters, but also in 
other CaRe asset classes which we 
expect to come to the fore over the 
coming years. 
We are already engaged in the delivery 
on a transactional basis of CaRe assets 
such as domestic EV chargers, solar 
and storage, and air-source heat 
pumps, and are working closely with 
the asset management division to 
develop the commercial models for 
further long-term growth beyond 
our smart metering pipeline.

Energy management 
Our energy management division, as 
well as continuing to support Industrial 
& Commercial (I&C) customers to 
manage and reduce their energy 
consumption, is focused on delivering 
this growth agenda.
Grid-scale battery storage
Whilst energy storage has always been 
a feature of the energy system, an 
exponential increase in short-term-
response grid-scale storage is clearly 
a vital requirement of the energy 
transition. This increasing requirement 
for energy storage is estimated by 
National Grid to be 18.7GW by 2030 
(of which 14.1GW is expected to come 
from battery storage compared to the 
c.2.1GW currently deployed), and 38GW 
by 2050.
This growth is driven by the increasing 
amount of intermittent renewable 
generation being connected to the 
grid, which creates an imbalance 
between generation and demand and 
results in price volatility. This imbalance 
– which has always existed – increases 
the spread between the cost to power 
up storage, and the value to discharge 
that energy. The spreads obtained by 
these balancing services drive the 
underlying economic model for our 
grid-scale battery storage, although 
we are also able to provide frequency 
services to the grid where it is value-
accretive to do so.
2022 performance: This has clearly 
been a transformational year for our 
energy management division, and 
specifically our grid-scale battery 
business. We grew our portfolio to 
760MW at 31 December 2022, of which 
610MW has been fully secured. We 
were also delighted to bring 140MW 
of grid-scale battery capacity through 
construction and into commercial 
operation, trading at our projected 
capex cost of £380,000/MW, and we 
currently have a further 150MW in 
advanced construction. 
Whilst it was important to demonstrate 
our decades of experience in the 
design and delivery of this kind of 
electrical infrastructure, it has been 
equally important to prove the long-
term sustainable revenue returns 
available to these assets. Our first sites 
have exceeded our previous financial 
expectations, delivering an annualised 
EBITDA of over £100k/MW with this 
performance significantly enhanced by 
70% of the revenues coming from the 
provision of frequency services. 
Whilst we expect the revenues from 
these frequency services to soften over 
time, we are confident in our long-term 
guidance of £57,000-£65,000 EBITDA/
MW. And, whilst we expect capex costs 
to increase to nearer £450,000/MW for 
future projects, the core electrical 
infrastructure of these sites has a 
40-year expected life (with battery cell 
replacement around every ten years) 
and the financial returns therefore 
remain very strong.
Going forward, we expect to continue 
to build our existing pipeline of projects 
in this growing market, and to continue 
to bring those projects in exclusivity 
through to being fully secured and into 
construction. We are targeting at least 
1.5GW of operational assets by 2030, 
which would represent a c.10% market 
share. We have proven capability to 
originate these projects – from initial 
site selection to construction and 
through to ongoing operation, trading, 
maintenance and asset management 
– as part of our end-to-end integrated 
model. For further information on our 
grid-scale battery storage business 
and the investor day we held in 
October 2022 at our first 50MW 
operational site at Burwell, please 
see pages 32 to 35 and page 38.
Energy services
Our traditional consultancy and energy 
management activities continue to 
grow and in particular, the roll-out of 
site-based energy efficiency measures 
was able to accelerate again post the 
COVID-19 pandemic. These capital 
projects are typically built on a 
data-led approach, as is the case with 
the smart heating control projects 
which we have been delivering on 
behalf of leisure and hospitality 
customers over the last year. 
In 2020 SMS launched its CaRe programme, engaging 
with stakeholders to consider the long-term assets 
required to transition the UK to net zero. To achieve 
this UK legislated target requires a fundamental shift 
to a smarter, more flexible energy system, capable 
of integrating substantial amounts of intermittent 
renewable generation whilst accommodating the 
increasing electrification of transport and heat.

The increase in wholesale energy prices 
has had a substantial impact on many 
I&C businesses and has strengthened 
the need to optimise the procurement, 
management and use of energy. We 
therefore see significant opportunity 
across our traditional consultancy and 
energy efficiency services, which seek 
to minimise the cost and volume of 
energy used.
During 2022, we began to develop 
integrated funded-energy solutions 
that materially address the net zero 
agenda and the long-term need to 
reduce and provide greater certainty 
over energy costs. By bringing together 
the individual asset classes we 
specialise in, such as distributed 
generation (e.g: solar PV) and storage,
directly connected to commercial 
properties, we are able to reduce 
reliance on energy from the grid and 
optimise the use of energy on-site. 
This approach can also mean that 
as other loads are introduced, such 
as heat pumps or EV charging 
infrastructure, additional infrastructure 
upgrade costs can be minimised along 
with the input price of energy to this 
new infrastructure.
The urgent need for businesses to 
address the effect of the increasing 
cost of energy on their bottom line, the 
continued necessity of reducing their 
carbon footprint and our ability to 
provide these integrated solutions 
across multiple asset classes provides 
significant growth opportunity for 
asset deployment in this sector.
EV infrastructure
The deployment and funding of EV 
charging infrastructure sits well with 
SMS’s core skills. We have over two 
decades of experience in the design 
and delivery of electrical infrastructure, 
from small connections to mobile 
phone masts to some of the largest 
electrical engineering projects in the 
country. It is this experience that we 
have brought to our grid-scale battery 
business over recent years, and which 
we are also able to utilise to deploy EV 
charging infrastructure.
Having developed our knowledge and 
experience of this sector over recent 
years through our involvement in projects 
such as the Virgin Media Park & Charge 
(VPACH) on-street charging scheme, this

Energy management continued
Decision-making in practice: investment in Clenergy EV
When assessing the market 
opportunity to install, own and 
operate EV charging infrastructure, 
particularly in the public infrastructure 
charging market, the SMS Board 
took into consideration a range of 
factors including our engineering 
capability, the quality and 
predictability of returns, and the 
technology platforms required to 
deploy and operate such assets.
With respect to technology platforms, 
whilst SMS clearly had the asset 
origination and management 
capability within our existing business, 
we needed to put in place chargepoint 
operator (CPO) capability to deploy 
firmware to EV chargepoint assets 
and to enable end users to operate 
and pay for using the infrastructure.
All options were considered, 
including:
•	 outsourcing that CPO management 
to a third party;
•	 licensing that CPO capability from 
a third party for SMS to manage / 
operate;
•	 developing our own CPO capability;
•	 investing in an existing third-party 
CPO platform.
After due consideration, and taking 
into account our strategic approach 
across our business to what we 
consider to be core IP technology 
requirements to manage assets, the 
Board felt that in order to manage 
risk and provide the appropriate level 
of platform flexibility and integration, 
our preference would be to invest in 
a CPO platform. The timescales and 
costs to develop our own capability 
were not considered the preferred 
solution, and having worked closely 
with Clenergy EV over the last year, 
we had identified them as our 
preferred third-party CPO partner.
In June we therefore agreed to take 
a minority stake in Clenergy, 
providing us with a direct interest in 
the development and success of their 
CPO platform which is now operating 
over 2,000 chargepoints across the 
country. SMS has invested an initial 
£2.0m to acquire a 25% shareholding, 
has the option to invest a further 
£2.0m after one year for an 
additional 26% interest, and has 
a further option to acquire the 
remaining shares after five years.
The Board believe that on a 
standalone basis Clenergy has the 
opportunity to grow a substantial 
business managing EV chargepoint 
infrastructure on behalf of a range 
of business and infrastructure owner 
customers across the UK, and 
potentially beyond. By investing 
in the business, not only do we seek 
to enable Clenergy to maximise the 
opportunity for its own platform, but 
also to ensure we have the end-to-
end turnkey capability to address the 
deployment and ownership of EV 
chargepoint infrastructure over the 
coming years.
This investment therefore 
complements SMS’s existing EV 
installation capabilities and will 
enable the Group to deliver a fully 
end-to-end integrated platform for 
EV charging infrastructure, a model 
the Group has already successfully 
adopted for its meters, data and 
grid-scale battery assets.

SMS Annual report and accounts 2022

delivery capability is now being aligned 
to the substantial requirement for 
destination, workplace, on-street, fleet 
and domestic EV charging infrastructure 
on a national basis. Commercial models 
vary from utilisation-based revenues to 
lease rental or subscription-based 
revenues. For utilisation-based models, 
we recognise that the location, type of 
charger (e.g.: rapid or slow) and unit 
rate of energy sold, are all critical 
considerations which will affect returns 
and are factors we will take into account 
when considering capital allocation.
As with our other asset classes, we seek 
to provide a turnkey solution, bringing 
funding together with engineering 
capability and technology platforms 
that allow us to deploy, manage and 
optimise our assets. Whilst much of that 
capability already resides within our 
METIS platform, during 2022 we also 
invested in Clenergy EV, a charge point 
operator (CPO) technology platform. 
Our partnership with Clenergy allows us 
to control both the charge of EV’s from 
any chargepoint type using open 
protocol software and also the revenue 
collection / payments for use of the 
chargepoint.
With this end-to-end operational 
capability in place, we are now investing 
in the development of a pipeline of 
activity in this area over the coming 
years, addressing the public 
(destination, on-street), workplace 
and fleet market segments.
We have also begun to extend our 
direct labour field capability into the 
domestic EV charging space, both 
through recruitment of experienced 
EV installation engineers and by using 
our training academy to train our 
meter engineers to address this 
market. Commercial models will vary 
from transactional to lease rental or 
subscription-based revenues.
SMS has been working with external 
support both to quantify the market 
size and to gain a deeper understanding 
of expected EV uptake, customer 
behaviour, traffic flows, appropriate 
locations for EV charging infrastructure 
and utilisation models. We expect the 
UK market to have c.500,000 public 
charging points by 2030, and for this 
number to grow to close to one million 
by 2040. The associated capital values 
(market size) are expected to be in 
excess of £20 billion. These numbers 
are consistent with many other forecasts 
in the market and give SMS comfort 
as to the size of the opportunity, the 
utilisation rates and the expected 
returns for our role as an asset owner.
Solopower (behind-the-meter 
smart solar and storage)
Supported by our FlexiGrid technology 
platform, our Solopower solution aims 
to reduce carbon emissions radically 
within the UK’s social housing stock 
through the use and optimisation of 
solar generation and battery storage. 
The increase in energy costs and 
substantial rise in fuel poverty, 
alongside the need to decarbonise 
housing, make clear the urgent need 
for these solutions.
We also seek to extend these solutions 
to the private market. We have capability 
in asset financing and subscription-
based solutions, and we see the 
opportunity to extend this capability 
to air-sourced heat pumps and 
domestic EV charging.
The UK social housing sector 
alone accounts for approximately 
five million homes.
In all of these cases our strategy 
remains the same: to deliver assets 
and services which reduce carbon 
emissions, by using our engineering 
resources and capability to deploy 
them, technology platform to optimise 
and manage them and providing 
capital where appropriate to fund 
them, in order to provide long-term 
secure recurring revenues. These 
markets also all share two key 
characteristics: they reduce carbon 
emissions, and they each provide a 
substantial growth market opportunity.

Grid-scale batteries: 
enabling the transition to a 
low-carbon energy system
The impact of this shift in the generation 
and demand mix can already be seen 
through the rising volatility of UK power 
prices and peak-baseload spreads 
over the last five years, which provides 
an increasing challenge to manage the 
capacity and frequency of the energy 
grid. The growing imbalance between 
instantaneous generation and demand 
is expected to further exacerbate the 
volatility spreads.
The growing need for and reliance on renewable 
energy to decarbonise electricity grids, alongside 
national energy security requirements, accelerates 
the fundamental long-term requirement to match 
demand with the intermittent supply.

This is where energy storage comes 
in to play. Grid-scale battery storage 
is needed to absorb excess energy 
generation, release power when 
demand is greater than supply, shift 
energy across time and locations, and 
provide real-time grid balancing. 
Battery storage also seamlessly 
operates with other demand-side 
flexible systems, like smart meters, 
distributed solar and storage, and 
electric vehicle charging infrastructure 
that can power down non-essential 
equipment at times of high system load 
or power up standby generation when 
grid prices peak.
1	 Calculated as the average of National Grid’s four forecast scenarios in its Future Energy Scenarios 2022.
National Grid has reflected this 
increasing requirement for grid-scale 
battery storage (from c.1.2GW in 2022) 
in its annual Future Energy Scenarios 
review. The forecast requirement 
has consistently grown each year, 
with the latest National Grid forecast 
requirement being for 18.7GW of 
energy storage by 2030, three-
quarters of which is expected to 
come from battery storage. By 2050, 
the requirement for total storage 
increases to 38GW, of which almost half 
is expected to be from battery storage.

In basic terms revenues from grid-scale 
battery assets are generated from two 
services: balancing services and 
frequency services. 
Balancing services are where we 
manage the timing imbalance between 
generation and demand by charging 
the battery when there is excess 
generation on the grid (and prices 
are cheap) and discharging when 
there is excess demand on the grid 
(and energy prices are high). It is the 
spread between these peaks and 
troughs from which we earn revenue.
This is similar to the services pumped 
hydro stations have provided for many 
years, but now in a grid that has a 
greater requirement for fast response 
times. Frequency services are where 
the batteries are operated on behalf 
of National Grid to ensure the grid 
stays within statutory frequency levels 
– protecting the grid against load 
fluctuations, blackouts etc. 
Our operational portfolio has now 
grown to 140MW and has been 
generating EBITDA per MW 
significantly ahead of our initial 
expectations. 
In the development and long-term 
operation of these projects we take 
our ESG responsibilities extremely 
seriously. All our supply chain partners 
are regularly audited, covering areas 
such as welfare, responsible sourcing, 
robust practices and environmental 
compliance including the recycling of 
battery cells at the end of their useful life.

Burwell grid-scale 
battery site visit
We were pleased with the response to our Capital Markets 
Day in June 2021 and so, in October 2022, we followed this 
up with a site visit to our first 50MW grid-scale battery 
storage project at Burwell. The Group has built a strong 
portfolio of grid-scale battery storage within a short 
period of time, and we wanted to give our stakeholders 
the opportunity to meet the grid-scale battery storage 
team, learn more about this asset class and see how these 
assets operate in real life. We developed the agenda and 
presentation materials taking account of feedback we had 
received from shareholders, analysts and advisers. 
The presentation included an overview of grid-scale battery 
storage and insight into the battery lifecycle and how these 
assets are optimised. We also showed videos from Barry 
Hatton (Director of Asset Management UKPN) who 
explained the importance of grid-scale batteries for 
balancing the grid, and from Daniel Greten (Head of Trina 
Storage EMEA) who discussed the manufacturing and 
sourcing of the batteries. The presentation was followed 
by a tour of the Burwell plant. 
The event was well attended and received by existing 
shareholders, potential investors and other stakeholders. 
More than 15 investors attended the presentation live on 
the day and many more have since viewed the recording 
on the Company’s website.

Why effective engagement is important 
Serving our customers is a key part of our purpose and 
we aim to provide an exceptional customer experience. 
To deliver this, we listen and engage, and strive to become 
a trusted partner. 
Maintaining open and honest relationships with our 
customers allows us to remain commercially competitive 
and secure both new and recurring long-term contracts. 
As the energy and utilities industry continues to navigate 
the UK smart meter rollout, it is important that we work 
collaboratively with energy suppliers to ensure we are 
meeting their service needs in an efficient and effective way.
Form of engagement
•	Listening and responding to customer feedback. 
•	Clear and structured lines of engagement for core 
customer groups.
•	All customers are assigned a strategic account 
director – a single point of contact with whom items 
can be discussed. 
•	For larger customers, dedicated contact centres are 
used to co-ordinate with end consumers. 
•	Separate specialist teams are allocated for planning 
and scheduling, commercial billing and general account 
management, ensuring regular communication is 
maintained. 
•	Regular service reviews to ensure we are addressing 
feedback from customers in a timely manner. 
Key topics of engagement during 2022 
We now ask all consumers for whom we have installed 
a meter to review our service via Trustpilot. This gives us 
much more feedback allowing us to continually improve 
our service. 62% of reviews award us the top 5-star rating.
We have continued to enhance our digital channels to make 
it easier for consumers to make bookings and c.60% of 
bookings are now digital. We still offer the traditional option 
of voice for those who prefer it.

•	Prompt payment practices. 
•	For larger suppliers, ongoing engagement through regular 
meetings and feedback sessions. Performance may also 
be measured against key performance indicators.
•	Where relevant, thorough tender and bid processes are 
carried out. 
Key topics of engagement during 2022 
Following a successful tender conducted in late 2021, SMS 
continued its journey towards a reduced carbon footprint 
by partnering with an alternative service provider providing 
shipments of goods to our engineer base. The new locker 
network has allowed SMS to double the amount of product 
shipped outbound, supporting the growth in our installation 
programme. Health and safety remains at the heart of all 
we do and so the new locker network also provides a more 
ergonomic solution for our engineers. 
As in recent years, SMS has experienced some product 
shortages due to continued global freight restrictions. 
The relocation of our warehouse to a much larger site 
has however allowed for greater purchases to be made 
to support our installation roll out plan and so has mitigated 
some of these challenges.
Policies and procedures around onboarding of vendors and 
ensuring prompt payment have continued to be adhered to. 
The development of our Electronic Quality Management 
system is allowing far greater reporting to support our ESG 
goals and aspirations.
Regulatory bodies

Why effective engagement is important 
The primary government regulator for the gas and 
electricity market in the UK is the Office of Gas and 
Electricity Markets (‘Ofgem’). Ofgem is the regulatory 
body by which our key customers are governed. 
In conjunction with other associations, groups and alliances, 
Ofgem provides comprehensive industry codes of practice 
that govern the operational, technical and health and safety 
issues associated with the installation and management 
of metering assets, to which both SMS and its customers 
must adhere. 
Maintaining regulatory compliance is crucial to our business 
success amongst customers who place substantial reliance 
on our reputation as a full-service provider.
Form of engagement
•	Attendance at regular meetings. 
•	Active participation in consultations and workshops. 
•	Representation on several boards and panels, including 
the Association of Meter Operators and the Smart 
Metering Operations Group.

and externally, in respect of the certifications and 
accreditations which we hold under MCoP and MOCOP, 
amongst others. 
Key topics of engagement during 2022 
We continue to participate in gas, electricity infrastructure 
and metering forums critical to the industry. These include 
several linked to the Retail Energy Code, which brings 
together several existing codes of practice and updates 
the governance of existing gas and electricity retail 
arrangements. As part of this, we have supported our 
energy supplier customers in understanding the code 
and the potential implications for their operations. 
We continue to participate in a new implementation working 
group set up by XoServe, which is focused on developing the 
role of hydrogen across the UK gas network. In time, SMS will 
be involved in developing the technical and training 
standards for this.
We continue to sit on several panels of the Institute of Gas 
Engineers and Managers, participating in the review and 
enhancement of key technical standards.
SMS continues to be a committee member of the

Assessing and addressing 
climate-related risks and 
opportunities
SMS first embarked on a journey 
to implement the recommendations 
of TCFD in 2020. As an organisation 
at the leading edge of the low-carbon 
transition, we are acutely aware of the 
importance of evaluating the impacts 
of climate change on our activities 
now and into the future. In 2022, we 
enhanced our climate change exposure 
evaluation by applying an emissions 
scenario to evaluate our near, medium 
and long-term exposure to the physical 
risks of climate change. Further details 
of this assessment can be found in the 
2022 Sustainability Report. 
We will continue to develop our 
approach to analysing climate risks 
with outputs reviewed by both our ESG 
Working Group and HSS Committee 
to ensure consideration is embedded 
into our decision-making.
We are committed to updating and 
sharing information related to our 
climate risks and opportunities with our 
stakeholders. Our CDP disclosure 
outlines our current aligned activities 
and further details our journey to best 
practice as we fully embed the TCFD 
principles into our strategic planning 
and everyday processes.

Governance 
Governance of climate-
related risks and 
opportunities
The Board has oversight of climate-related issues through three key channels: active performance 
evaluation and management through the Health, Safety and Sustainability (HSS) Committee, system 
governance through our audit processes, and our risk and opportunities frameworks. Each of these 
channels enable oversight, and the ability to ensure the integrity and integration of climate issues 
into all business decisions at top level.
Our HSS Committee monitors short, medium and long-term sustainability risks, alongside their 
probability and impact and our corresponding mitigation strategies. 
Strategy 
Actual and potential 
impacts of climate-
related risks and 
opportunities on 
business strategy 
and financial planning
Opportunities:
SMS is well placed to support the UK Government’s ambition to be net zero by 2050. We can do this 
by continuing to leverage our well-established energy services as the UK transitions to a more 
sustainable and low-carbon economy. We continue to develop new opportunities aimed at 
mitigating climate change and these are embedded in our business strategy for the short, 
medium and long term. See pages 12 to 17.
Risks:
We are keenly aware of the potential impacts of fuel costs and taxation linked to the cost of operating 
our fleet and building estate. To mitigate against future increases in carbon taxation, SMS has 
committed to reduce emissions to net zero by 2030. Our net zero roadmap includes transitioning 
from internal combustion engine to electric vehicles and installing on-site renewable generation. 
We have also identified areas of potential physical climate-related risk, such as extreme weather 
events which could affect our physical locations, road-based employees, and our supply chain. In 
2022, SMS carried out a quantitative and qualitative physical climate change exposure evaluation 
across our facilities (buildings and battery sites) utilising a recognised climate scenario, SSP-4.5. 
Whilst climate-related change will have a profound effect on business in the broader sense, the risk 
is very low for SMS specifically, with key risks and opportunities detailed within our Sustainability 
report and CDP disclosure.
Risk management 
The processes used 
to identify, assess 
and manage climate-
related risks
We have carried out qualitative and quantitative explorations of potential areas of concern utilising 
best practice guides as a framework, including detailed climate exposure evaluation of our physical 
assets including offices, warehouses and battery sites. Further information can be found within the 
Sustainability Report.
Climate risk is integrated into our Group risk register and monitored by the Audit Committee; see the 
Risk report on pages 62 to 69 for details on the Group’s risk management processes. 
Climate risk currently has a low-risk rating and is therefore not considered a principal risk for risk 
reporting purposes.
Metrics and targets
The metrics and targets 
used to assess and 
manage relevant climate-
related risks and 
opportunities
Our Scope 1, 2 and 3 emissions are disclosed within our emissions reporting table, including further 
descriptions of sources. See page 48.
Our ‘net zero by 2030’ target, progress and roadmap demonstrate our commitment to reducing 
emissions. Transition milestones are embedded into our financial and strategic business planning.

UK/EU taxonomy
The EU taxonomy (‘the Taxonomy’) 
enables the classification of business 
activities as ‘environmentally 
sustainable’. The aim of the Taxonomy 
is to provide transparency to both 
investors and businesses and to 
prevent greenwashing. The Taxonomy 
supports sustainable investors and 
investments, by providing clear 
quantitative demonstrations of 
business activities and revenues 
against specific criteria.
Under the EU’s Taxonomy, a business 
must pass three key tests to be classed 
as environmentally sustainable. It must: 
•	 make a substantial contribution to 
one or more of the Taxonomy’s 
environmental objectives; 
•	 do no harm under all environmental 
objectives; and
•	 comply with the minimum safeguards 
covering social and governance 
standards.
We have assessed the extent of our 
alignment with the EU Taxonomy, in 
order to support our investors and 
prepare for the UK Taxonomy. Our 
assessment shows strong correlation 
between all our services and the 
Taxonomy requirements, summarised 
in the table below.
We will continue to align with the 
requirements of the Taxonomy as 
these develop, and disclose our 
alignment, assessing the technical 
screening criteria and revenue from 
applicable activities. 
Our net zero ambition
Our ‘net zero by 2030’ target will see us 
drastically reduce our organisational 
carbon emissions. It encompasses 
Scope 1 and 2 carbon emissions that 
derive from our building estate as a 
result of heating, cooling and electricity 
use, and the consumption of fuel by 
our tracked fleet. Our ambition is to 
achieve a 100% absolute reduction in 
these emissions by 2030, which aligns 
with the level of ambition required to 
limit global warming to 1.5°C.
Our net zero target currently excludes 
the emissions associated with 
operating our grid-scale battery 
storage sites, the first of which became 
operational in January 2022. Once we 
have achieved a full year of data we 
will establish a baseline from which we 
can set an intensity-based target that 
aligns with the Science Based Targets 
Initiative (SBTi) in 2023.
2022 progress 
In line with our net zero strategy, during 
2022 we implemented a range of 
sustainability upgrades at one of our 
core sites in Cardiff. This project has 
focused on reducing energy 
requirements through upgrading the 
building fabric to improve thermal 
performance, generating renewable 
energy with 30kWp capacity of solar 
photovoltaic and providing a level of 
self-sufficiency with battery energy 
storage. The final step will involve the 
installation of an air-source heat pump 
and mechanical cooling and ventilation 
system that will mitigate the effects of 
increasing summer temperatures. 
Upon completion, this project is 
expected to reduce building emissions 
by up to 70%, exceeding Science Based 
Target requirements, and will serve as 
a blueprint for upgrading modest office 
buildings to achieve significant 
decarbonisation and climate change 
adaptation.

Our fleet net zero transition saw 11 
hybrid vans received at the end of 2021 
tested as trial vehicles to evaluate their 
viability, distance capabilities and 
suitability for our business purposes. 
Following the trial, we have decided to 
move forward with replacing the first 
quota of Internal Combustion Engine 
(ICE) vehicles with mild-hybrids, which 
use a battery-powered electric motor 
in support of a conventional petrol or 
diesel engine to improve fuel economy 
and reduce emissions. This marks 
another milestone in our net zero 
roadmap, as these vehicles will allow 
us to continue to improve the efficiency 
of the fleet before transitioning fully 
to zero-emission vehicles. 
We launched in 2021, the DriveGreen 
Scheme, a salary sacrifice scheme that 
has supported a further 11 car drivers 
migrating to full EV cars or PHEVs.
2023 outlook and priorities
The first half of 2023 will see the 
sustainability upgrades at our office 
in Cardiff finalised, leading us into the 
next phase at our second site which 
will include determining the bespoke 
solutions we need to implement based 
on the completed 3D performance 
simulation modelling of the building. 
In the first half of 2023 we will also be 
welcoming 100 mild hybrid vans into 
our fleet and trialling one full EV van. 
This full EV van will be fully fitted with 
all the equipment carried by a dual-fuel 
engineer to ensure true-to-life 
evaluation of performance. The trial 
will enable us to evaluate the currently 
available EV technology, focusing on 
distance capabilities, charging

Our environmental 
performance
Emissions reporting
Our footprint is the carbon produced 
by our operational activities. We utilise 
the internationally recognised GHG 
Protocol to ensure comprehensive 
and standardised data calculations. 
Our reporting covers all emissions 
from our business activities, and all 
sites and operations during calendar 
year 2022. Full methodology can be 
found on our website.
Our Scope 1 calculation looks at the 
energy consumed by our fleet vehicles, 
gas and oil consumed across our 
offices, warehouses and training 
centre, and fugitive emissions from air 
conditioning. Our Scope 2 calculation 
looks at our electricity consumption. 
Scope 3 accounts for the emissions 
generated within our value chain. 
In 2022 we worked with our assurance 
providers to ensure accuracy and 
completeness of our Scope 1, 2 and 3 
carbon reporting. Further details can 
be found within our Sustainability 
report and the assurance statement

actual consumption data from service suppliers and newly released carbon conversion factors, which has led to a restatement of data within the table.

2022 ‘footprint’
We saw a significant increase in smart 
meter installations during 2022, which 
resulted in an increase of 54% in our 
fleet-related carbon footprint on the 
previous year, as an additional 175 
vehicles were added to the fleet to 
service this demand. We have 
continued to de-couple business 
growth from emissions and have been 
successful in improving overall fuel 
efficiency with the amount of carbon 
emissions emitted per vehicle reducing 
by 5% since 2019. 
The full operation of our first battery 
site in Burwell and the commissioning 
of our second site in Barnsley in 2022 
has changed the landscape of our 
business emissions. The emissions 
resulting from the net consumption of 
electricity from our battery assets, also 
known as the operational emissions, 
are now reported under our Scope 2. 
The development of batteries will 
support the integration of more 
renewable sources of electricity into 
the grid and will enable a low-carbon 
energy system for all in future. As this 
is realised we will see a sustained 
reduction in emissions generated by 
our battery sites.

Our ‘handprint’
To reach an understanding of our 
total sustainability we take a holistic 
view of our company sustainability, 
which includes quantifying both the 
positive impacts from our products 
and services (our handprint), and the 
negative impacts from our business 
operations (our footprint). We use this 
‘net positive’ perspective to align our 
strategy for business growth, financial 
benefits and sustainability gains: 
investing in the development of assets 
and services which deliver carbon 
reductions for our customers and their 
end consumers.
Our ‘handprint’ is the carbon mitigation 
achieved by our customers through the 
impact and delivery of our energy 
services and solutions, such as smart 
meters. We use savings data from 
smart meter energy research and from 
delivered energy efficiency projects to 
calculate our total handprint.

Our people
Health and wellbeing 
We proactively support a holistic 
wellbeing agenda at SMS. Good health 
and wellbeing are paramount. We 
believe the happiest colleagues are 
those who are engaged and included, 
whose wellbeing is priority, and who 
feel part of the Company’s mission 
and purpose. We therefore provide 
a host of wellbeing-focused benefits 
for all employees including access to 
an employee assistance programme 
which offers 24/7 confidential support; 
SmartHealth, a free support package 
for employees including online GP 
appointments and access to health 
experts; the My Healthy Advantage 
app, which gives access to a wealth 
of health and wellbeing resources, and 
Medicash, which supports employees 
with day-to-day medical expenses. 
As part of ‘putting our people first,’ it is 
important to us that employees are not 
only supported whilst at work but also 
in their lives outside work. This includes 
supporting employees through their life 
changes as they grow their families, 
develop their careers, or encounter 
difficulties. We therefore have a 
bespoke wellbeing intranet page with 
resources across three pillars: mental, 
physical, and financial health, and have 
enhanced wellbeing policies, some of 
which include fertility treatment, 
maternity, and adoption leave.
In 2022, we launched bespoke internal 
training workshops for line managers 
on employee health and wellbeing to 
equip them with the knowledge and 
tools to support their employees 
through life challenges. And we 
upskilled a further eleven of our 
employees to become accredited 
mental health first-aiders taking our 
number of trained employees to 31. 
To support effective leadership and 
management across the Company and 
to further embed and maintain health 
and wellbeing as part of everyday 
activities, our bespoke ILM/CMI 
recognised Management Development 
Programme includes a module titled 
‘Being A Mindful Manager’, which over 
100 managers have completed.
We also offered all our employees 
the opportunity to attend an external 
training course on ‘Talking Wellbeing’ 
delivered by Mindful Employer. This 
three-hour workshop is designed to 
improve the understanding of mental 
health conditions, build team and 
individual resilience, and develop 
the skills and confidence to have 
constructive discussions about 
mental health within the workplace. 
80 of our employees participated.

Employee engagement 
At SMS, we are committed to putting 
our people first – a philosophy 
embedded within our company culture 
and our five core values. We can only 
do this by actively listening to our 
employees and encouraging feedback 
and discussion on the topics that 
matter most to them. 
We hold a bi-monthly forum, The Voice, 
which gives our people a platform to 
express their views and make 
suggestions on how we can make 
SMS a great place to work. We also 
launched ‘Your Thought is Sought’, 
our employee suggestion scheme. 
We carried out our third 
external employee 
engagement survey from 
Best Companies. The 
response rate once again 
rose, and we were delighted 
to retain our ‘One to Watch’ 
accreditation from Best 
Companies for good levels of 
employee engagement. 
We also consulted with our staff on 
hybrid working using a survey. This 
informed our hybrid working policy 
which we then introduced using a short 
video which gave staff helpful guidance 
on how to maintain wellbeing and keep 
SMS culture and values alive. 
Recognition and reward
We have been a ‘Living Wage’ 
employer since 2020. The Living Wage 
is scheduled to go up in May 2023, 
but to give further support to our 
employees on entry-level salaries, 
we brought in the increase six months 
early, increasing their rates to £10.90 
per hour from 1 November 2022.
As well as being a ‘Living Wage’ 
employer, in 2022 we also became an 
accredited ‘Living Hours’ employer. 
This reflects our commitment to 
provide our employees with the 
security of hours that they need.
To reinforce our culture, we also 
continued our Living Our Values (LOV) 
Awards which, each quarter, recognise 
staff who have consistently displayed 
one or more of the five SMS core values 
and associated behaviours.
Sustainability continued

Our activities
Throughout 2022 we partnered 
with a number of organisations 
and launched initiatives to raise 
employees’ awareness across 
a range of topics and signpost 
them to further specialist 
support. 
For example, we:
•	 relaunched the SMS Wellbeing 
page on our intranet which 
provides lots of free support 
and advice, with external 
signposting;
•	 renewed our two-year 
voluntary pledge to Mindful 
Employer and their Charter for 
Employers Positive about 
Mental Health;
•	 invested again in the Tommy’s 
Pregnancy and Parenting at 
Work programme;
•	 supported Baby Loss 
Awareness Week 2022 and 
National Fertility Awareness 
Week;
•	 supported Mental Health 
Awareness Week, National No 
Smoking Day, World Mental 
Health Day, and International 
Men’s Health Week;
•	 joined the Employers Initiative 
on Domestic Abuse;
•	 joined the National Suicide 
Prevention Alliance;
•	 supported National 
Schizophrenia Awareness Day; 
and
•	 committed to being a 
Menopause Friendly Employer.
Decision-making in practice: 
discretionary cost-of-living payment 
We were aware of the impact of 
the rising cost of living on our staff 
as we approached winter, and in 
November 2022, we made a one-off 
discretionary payment to all but our 
highest paid employees to help 
them through this time. 
The Board approved this payment 
after balancing the interests of 
employees and shareholders. The 
payment demonstrates one of our 
core values – putting our people 
first. The Board judged this action 
would be in the long-term interests 
of the Company and would help 
meet its responsibility to the 
Group’s staff.
 “Given the current climate of finances and how much everything has 
shot up in price, SMS couldn’t have timed the payment for all staff 
below senior management any better. I know a lot of staff will have 
been having serious concerns due to the time of year, Christmas, 
and needing to use more energy. Personally I’ve never worked for 
a company that thinks about its staff like this. I’m sure we have all had 
a nice voucher at work and maybe been given a flyer on a Friday, but 
the amount of money SMS has shared back into the business direct 
to its staff is outstanding! Whoever was involved in this decision has 
made more of an impact than they realise, and they have satisfied 
a lot of families affected by the country’s situation.”

Website
We launched our new Group website, 
integrating our refreshed brand and 
creating an online space that reflects 
the full scale of our ambition. We wanted 
our website to bring our people and 
culture to the very forefront of our brand.
Talent management and 
development
We strive for best practice when it 
comes to leading, developing, and 
supporting our people and therefore 
we invited Investors in People to assess 
us. We were delighted to achieve Silver 
accreditation across the Group.
Over the year we built on our activities 
to develop our people at all levels 
within the organisation:
•	 we continued the rollout of our Talent 
Management and Succession 
Planning Framework which helps 
us find and then develop, nurture, 
and retain our future leaders;
•	 we developed more of our 
managers and team leaders 
through our bespoke Management 
Development Programme which 
is recognised by the Institute of 
Leadership & Management (ILM) 
and the Chartered Management 
Institute (CMI);
•	 we launched new training courses; 
topics requested included resilience 
leadership, and giving and receiving 
feedback; and
•	 we expanded our apprenticeship 
offering, with twelve of our people 
obtaining their apprenticeship 
qualification in 2022, and we currently 
have a further 21 working towards 
their professional qualification.
Equality, diversity, 
and inclusion 
In October, we unveiled our ‘Levelling 
Up Impact Report’, which has been 
developed in partnership with The 
Purpose Coalition. The report, which 
was presented to business leaders 
and MPs in Westminster, outlined 
how we are making a positive social 
and environmental impact, which has 
become even more important amid 
the current cost-of-living challenges. 
The Levelling Up Goals provide a 
framework to help organisations 
identify gaps in access to opportunity, 
address common socio-economic 
barriers that prevent people from 
achieving their potential, and hence 
help narrow regional inequality and 
improve overall living standards in 
the communities in which they operate.
The way we embrace diversity and 
inclusion in our recruitment and people 
management was recognised when 
SMS won ‘Best Diversity & Inclusion 
Initiative’ at the S1 Awards. We are 
also proud to announce that we have 
signed up to a company partnership 
with the Women’s Engineering Society. 
This partnership helps us to support 
women in engineering careers and 
to encourage young girls to view 
engineering as a career option. 
We have also introduced a reverse 
mentoring programme via Disability 
Connect. Disability Connect provides 
organisations with disabled mentors 
who help raise awareness of the issues 
disabled people face in the workforce 
and provide insight that we will use to 
ensure SMS is accessible and 
welcoming to all.

Giving something back
We are mindful of our responsibility not 
only to our employees, but also to the 
communities within which they live. With 
this in mind, in 2022 we enhanced our 
support for our local communities 
through several initiatives:
•	 Three of our senior leaders became 
mentors on our continued programme 
with the Aleto Foundation charity. 
This is focused on identifying and 
developing the next generation of 
leaders from BAME communities 
who may historically have found it 
challenging to access opportunities 
due to their backgrounds.
•	 We committed to support charities 
within the local communities close 
to our offices and for the next three 
years will donate £90,000.
•	 We matched the charity fundraising 
efforts of many employees through 
one-off corporate donations to their 
chosen causes.
•	 SMS employees volunteered their 
time to provide career advice at 
several local schools, the HR team 
helped improve a school play area 
near Bolton, and a group of our 
senior managers volunteered their 
time at the Bolton NICE foodbank 
and at a Cardiff nursing home.
•	 We participated in various local 
school engagement activities such 
as mock interview days, careers fairs, 
and career networking.
•	 We continued to support Career 
Ready with their mentoring 
programme.

Giving something back
As part of our commitment to ‘Levelling Up’ and sustainability, we have 
targeted our social responsibility efforts at those communities that need 
help the most, particularly in deprived areas close to where we operate as 
a business around the UK. For example, a team of SMS volunteers spent the day 
at Bolton NICE foodbank, which provides support to children, families, and 
individuals who are experiencing difficulties. Also, members of our HR team 
volunteered at Wesley Primary School, situated near our training academy 
and contact centre site in Bolton, as part of a social community activity. 
We have also confirmed our commitment to support charities within local 
communities close to some of our offices, and for the next three years we 
will donate £90,000, between Beatson Cancer, Velindre Cancer Centre, 
The Bluebell Wood Hospice and Bolton Hospice. Following this commitment, 
we will undertake a company-wide survey to decide which new charities will 
receive our support.

Gender pay gap 
reporting 2022
SMS supports and encourages gender 
diversity amongst its workforce and 
welcomes the requirement for gender 
pay gap reporting, introduced to 
increase pay transparency, and is 
committed to diversity and inclusion 
throughout the business.
Gender within SMS1
Overall, the SMS Group workforce is 
30% female and 70% male. As we are 
part of the historically male-dominated 
engineering industry, it is no surprise 
that our organisation has such a wide 
gender split (weighted towards men), 
and that a gender pay gap exists.
The mean gender pay gap in hourly 
pay for the SMS Group is 22.4%, and 
the median gender pay gap is 37.2%.
Specifically within SMS:
•	 most of our employees are engineers, 
and this is a profession with more 
men than women;
•	 there are more men than women 
in senior roles;
•	 there are more women in part-time 
roles; and
•	 there are more women in lower-
paying roles.
It is worth noting that most of these 
issues are prevalent throughout the 
UK and internationally, so are not 
unique to SMS. 
As can be seen via ‘Engineering UK’ 
(published online via Women’s 
Engineering Society) who provide 
workforce statistics, in March 2022: 
•	 Women make up 16.5% of all 
engineers, compared to 10.5% 
reported in 2010.
•	 This represents a 6 percentage point 
increase in the proportion of women 
in the engineering workforce.
•	 The actual number of women working 
in engineering roles also increased 
from 562,000 in 2010 to 936,000 
in 2021.
The percentage of female employees 
has decreased in the lower middle pay 
quartile by 11% as during the data set 
period, there was a significant increase 
in headcount in engineering roles, which 
is predominantly a male dominated 
field, and the upper middle pay grade 
has 2% more women. However, there 
continued to be significantly more male 
employees (in senior roles) in the upper 
middle and top quartiles, which 
exacerbates our gender pay gap. 
That said, for the SMS Consolidated 
Group, the mean hourly pay gap has 
decreased and thus improved by 
1.2% which is a positive. 
During 2022, we promoted 13 women 
internally into management and 
senior level positions and appointed 
4 women externally into management 
level positions.
Taking action – our strategy
SMS supports and encourages a 
culture of gender diversity amongst its 
workforce. It is through the contribution 
of ‘Our People’ from of all backgrounds 
that ensures our business is successful, 
as only a diverse, inclusive, and 
engaged workforce will produce the 
solutions we need to tackle the varying 
challenges faced by our business, and 
industry leading thinking will transition 
the energy market.
We are prioritising the following 
areas for action: diversity and inclusion 
will remain a strategic driver. We will 
utilise external accreditations and 
memberships for support (i.e. WES), 
together with internal tools including 
the SMS voluntary EDI monitoring form, 
with a focus on increasing completion 
rates. We will also continue to use our 
group pay and reward framework. 
This will help ensure there is no bias 
towards either gender from the point 
of recruitment, through to salary 
conversations and progression 
opportunities. We continue to actively 
promote gender balance within the 
SMS Group and explore how we can 
continue to attract women into our 
organisation, to create a more even 
gender balance, specifically within 
our engineering workforce. 
1	 We collected our data on 5 April 2022, when the total workforce for the consolidated Group consisted of 388 women and 896 men 
(including Non-executive Directors).
2	 Senior management is defined as employees (including executive directors) who have responsibility for planning, directing and controlling 
the activities of the Group.

Health and 
safety
Overall, 2022 was a positive year for 
safety, health, environment and quality 
(SHEQ) performance across the Group. 
We continued to build on the momentum 
of the previous years with wide-ranging 
improvement targets across our SHEQ 
metrics. Our rolling action plans ensured 
we stayed on course and again we 
delivered some excellent results.
The contractors on our multiple 
grid-scale battery storage sites 
have also overcome many challenges, 
most notably weather-related, during 
the construction phases on our sites. 
Again, we are pleased to report zero 
RIDDORs on our five construction 
sites during 2022. 
 
 “We remain committed to being 
a safe, secure and reliable 
organisation which protects 
the safety and wellbeing of 
our people and our customers.”
Key highlights
•	 Zero injury RIDDORs, including 
during the construction of our 
grid-scale battery storage sites.
•	 Maintained certification for the 
ISO 9001, 14001, 27001, 45001 
and 50001 standards. 
•	 Successfully extended the 
scope of ISO 50001 to include 
additional SMS sites. 
•	 Extended the scope of Safe 
Contractor accreditation to 
include SMS Connections 
and CH4 Ltd. 
•	 IOSH Contractor Management 
Training commenced.
•	 More live dashboards for 
monitoring performance.

Accidents and incidents
For 2022, we are again delighted 
to report zero injury RIDDORs. Our 
rates for other less serious incidents 
were in line with last year’s 
outstanding results.
•	 No injury RIDDORs were reported, 
resulting in an Accident Frequency 
Rate (AFR) of zero for the second 
year running.
•	 Lost Time Incident Frequency Rate 
(LTIFR) at 0.21 per 100,000 hours 
worked (2021: 0.17).
•	 Non-Lost Time Incident Frequency 
Rate (NLTIFR) at 0.53 per 100,000 
hours worked (2021: 0.52).
•	 Total Recordable Incident Frequency 
Rate (TRIFR) at 0.74 per 100,000 
hours worked (2021: 0.69).
•	 Group technical performance has 
improved significantly over the year 
finishing at 15 incidents per 100,000 
installs (2021: 28). This is commendable 
given the significant increase in 
installations and the associated 
works in the year. 
Grid-scale battery storage
During 2022, the construction and 
operation of our grid-scale battery 
storage (GSBS) sites continued at pace. 
We currently have three sites under 
construction and three operational. 
The sites have been closely monitored 
by the SHEQ and GSBS teams and we 
are again pleased to report that there 
have been no significant injuries or 
incidents on any of the GSBS sites 
in the period. 
The collaborative ethos that exists 
between all stakeholders has ensured 
that the site workers are safe and 
healthy, and the works are having 
minimal impact on the public and the 
local environment. We are also pleased 
with the biodiversity improvements 
that are either in place at our live sites 
or planned at our sites under 
construction. Planning is also underway 
for lessons learned forums with our 
contractors as we strive to continually 
improve our understanding of how best 
to construct and operate our assets. 
Occupational health
We continue to maintain a strong focus 
on occupational health, particularly 
mental health, and have a number 
of tools and services at our disposal 
to assist our employees. We are also 
acutely aware of the pressures facing 
our emergency services nationally and 
have invested heavily in emergency 
response training for our employees 
as well as equipment within each of 
our workplaces. This will ensure that 
we can deal with many of the issues 
that we would otherwise normally rely 
on the emergency services to cover. 
Our employees have come forward 
in significant numbers to volunteer for 
the various training packages on offer 
and again demonstrated their total 
commitment to playing their part in 
keeping our workplaces as safe and 
healthy as possible. 
Mental health issues remain a global 
concern and we have continued to 
focus on these and related issues. By 
drawing on the latest evidence and 
using examples of good practice from 
around the world we are highlighting 
and informing our employees on steps 
they can take to maintain and improve 
mental health. We are also working 
with our stakeholders to deepen the 
commitment given to mental health, 
reshape the environments that 
influence mental health, and strengthen 
the systems that care for mental 
health. These efforts will ensure that 
our people remain healthy and are fully 
aware of the multitude of conditions 
that are directly and indirectly related 
to mental health. Our support to our 
employees is unwavering. 
 
Employee forums
At SMS, we have a number of employee 
forums that contribute to our ongoing 
SHEQ improvement journey. The 
forums are led by other functions 
including human resources, compliance 
and operations. They allow employees 
to raise and discuss SHEQ issues 
openly with feedback provided from 
SHEQ if required. The business also 
benefits from the many ideas that are 
presented at the forums by employees. 
A recent example of this is a high-
impact messaging service, using 
Microsoft Teams, that was 
implemented after discussions on 
communications at a forum. 
Industry campaigns and 
communications
Our communication programme is a 
crucial part of our SHEQ management 
system. Throughout the year, we 
participated in industry campaigns 
and delivered a range of internal 
communications via our numerous 
media platforms. In 2022, we introduced 
two new communication channels 
designed for speedy delivery of 
messaging, high impact and effective 
collaboration. These channels 
supplement what we already have in 
place and ensure that our employees 
are kept up to date on health and 
safety issues by various means. 
Unfortunately, Gas Safety Week 2022 
was cancelled due to the death of Her 
Majesty Queen Elizabeth II. Our 
participation in the campaign is an 
annual highlight and we decided to 
dedicate the time and resource to 
other improvement initiatives including 
a new award for safety and quality for 
our engineering workforce. This was 
well received and maintained a focus 
on safety and quality long after the 
usual Gas Safety Week activities.

our reporting. The Power BI dashboards 
offer up-to-date information on 
performance and enable us to focus 
on any areas that require attention

our people and those affected by our 
undertakings safe and healthy. Our 
ambitious targets and action plans will 
continue to drive improvements across 
the business. We continually adapt to 
new work streams. In 2022 our grid-
scale battery storage facilities moved 
to an operation and maintenance 
status and we are now preparing for 
a major leap forward in domestic 
settings that will include electric vehicle 
charging points, heat pumps and solar 
photovoltaic. We have also embarked 
on a major sustainability-focussed 
refurbishment of our Cardiff office. 
We remain committed to being a safe, 
secure and reliable organisation and 
look forward confidently to 2023.
Health and safety policy
The annual review of our health 
and safety policy and associated 
arrangements was carried out in 
April 2022 and published on the 
Company’s intranet. The policy, 
which is a statement of intent, 
drives improvements across our 
management systems and other 
related processes. For example, 
a number of working groups were 
established during 2022 to review 
personal protective equipment (PPE), 
training and our fleet. The outputs 
from the groups included new higher-
grade PPE, an induction training 
review and a revised procedure for 
company vehicles.

Putting our people first
Our core values and behaviours
Our Code of Conduct provides the 
foundation on which our standards are 
built and our approach to environmental, 
social and governance issues, detailed 
further on our website at www.sms-plc.
com/corporate/sustainability, sets out 
clear expectations of how to conduct 
business in an ethical way. 
Although not fully inclusive of everything we do, the following table demonstrates the key policies that we currently 
implement and monitor in this area: 
Ethical, fair and diligent governance 
underpins all our business activities. This 
is supported by extensive training and 
the continuous education of our people, 
from a full corporate induction through 
to ongoing learning and development. 
Our key policies which recognise, 
support and protect our employees’ 
human rights – and thus drive our 
ethical business practices – cover 
the following areas: 
•	 anti-bribery and corruption
•	 modern slavery

policy
Dignity at work policy
We respect the rights 
and dignity of all people 
when conducting our 
business. 
Our focus is on ethical 
business practices for 
our people, customers 
and wider communities.
Our policies and 
approach are 
embedded in our culture. 
They are communicated 
at induction, through our 
employee handbook and 
via e-learning modules.
Employees are required 
to immediately report 
any instances of a 
breach in human rights 
to our Group HR 
Director.
During the year, there 
were no reported 
breaches.
Anti-bribery 
and 
corruption
Anti-bribery and 
corruption policy
This policy includes 
guidance to employees 
on the giving, receiving 
and recording of 
business gifts and 
hospitality, together with 
other areas of specific 
risk, and is reviewed 
regularly to ensure it 
remains fit for purpose.
All employees are 
required to accept and 
adhere to the policy.
We do not deal with 
prospective contractors 
or suppliers known to pay, 
or suspected of paying, 
bribes. This helps prevent 
bribery and other forms 
of corruption.
Any breaches of policy 
are reported to our 
General Counsel and 
investigated. 
During the year, there 
were no reported cases 
of bribery or corruption.
Modern

human 
trafficking
Modern slavery policy
Modern Slavery 
Statement
We do not tolerate 
modern slavery within 
our immediate business 
or wider supply chain.
Although the risk of 
modern slavery and 
human trafficking in 
relation to SMS is low, 
we do monitor our 
supply chain to ensure 
we fully understand and 
mitigate the risk.
Contracts with new 
suppliers require a 
warrant to us that they 
are compliant with the 
terms of the Modern 
Slavery Act 2015. 
Existing agreements in 
place for our Tier 1 
vendors already cover 
modern slavery. 
Key staff training is 
regularly reviewed.
Any breaches of this 
policy are reported to 
our General Counsel 
and, where required, to 
the relevant authorities.

Risk report
Our established risk management framework, and the wider system of internal 
control, continues to adapt in line with our growing business and the challenging 
macroeconomic environment. The Board has overall responsibility for governance, 
risk management and internal control. In support of this, we operate robust risk 
management processes, which are embedded within everyday business activities 
throughout the Group. The risk management framework on page 63 highlights the 
main responsibilities for the management and oversight of risk within the Group.
The macro-economic environment 
presented several external challenges 
during the year, including continued 
volatility within energy markets, high 
inflation and the remaining impact of 
the pandemic. The ongoing conflict in 
Ukraine has placed additional pressure 
on the global energy supply chain. 
Rising energy prices, subsequent 
cost-of-living increases, and the risk 
of supplier insolvency remain key 
challenges. 
Our customer exposure is inherently 
mitigated due to the Supplier of Last 
Resort (SoLR) process, whereby Ofgem 
directs a gas or electricity licensee to 
take over responsibility for a failed 
energy supplier’s customer portfolio. 
This protects future metering charges, 
which are raised to the newly 
appointed energy supplier regardless 
of whether they are an existing 
contracted customer with the Group, 
and so caps our financial exposure at 
amounts already accrued or billed, but 
not yet settled. 
In addition, we have robust commercial 
billing arrangements, an established 
credit control function and significant 
available funding under our debt 
facility which help to absorb market 
shocks like this. The Board closely 
monitors the situation and receives 
regular reports on the Group’s cash 
and debtor positions. 
Group internal audit continued to work 
closely with the Audit Committee, 
executive leadership team and 
departmental teams throughout 2022 
to support the continuous 
improvement of risk management 
processes within the Group. This work 
included facilitating regular risk 
workshops, which are used to: 
•	 identify new risks and review and 
update existing risk ratings;
•	 identify appropriate new mitigating 
actions; and 
•	 assess progress towards completion 
of identified mitigating actions.
The Board and Audit Committee 
receive regular reporting on the outputs 
from risk management activities. During 
2022, Group internal audit performed 
several internal audit reviews of 
specific risk areas including cyber 
security, grid-scale batteries, treasury 
management, financial controls over 
billing and fixed asset management 
and disaster recovery planning.
Understanding our risks
The organisational risk management 
framework comprises the recording 
and management of ‘top-down’ 
strategic risks, which are discussed by 
the Board and executive leadership 
team, as well as ‘bottom-up’ risks, 
which capture potential operational 
issues at a departmental level. Our 
risk assessment model considers: 
•	 the probability of a risk crystallising; 
and
•	 the potential impact if the risk did 
crystallise. 
Risk governance 
and management
62
SMS Annual report and accounts 2022

These principal risks and uncertainties 
have been scored and placed on the 
risk heat map on the next page, which 
is a matrix of probability and impact. 
Our model considers each risk from 
two different perspectives: 
•	 the extent of inherent risk 
(before mitigating controls have 
been implemented); and
•	 the extent of residual risk 
(after mitigating controls have 
been applied).
The heat map provides a picture of 
residual (mitigated) risk at the corporate 
level and allows us to assess the 
effectiveness of our internal control 
environment and take further action 
as appropriate. The matrix also 
enables the Group to focus its 
internal audit activity.
We continually evaluate our principal 
risks in line with our strategic priorities 
and the prevailing industry and market 
conditions. Our risk management 
activities include: 
•	 frequent risk workshops to update 
corporate and departmental risk 
registers;
•	 detailed reporting of significant 
strategic risks to the Board; and
•	 consideration of new and emerging 
significant global, industry and 
economic risks.
Risk management framework
Board/Audit Committee
The Board is responsible for setting the tone at the top and monitoring business performance. This includes regularly reviewing 
risks that could impact achievement of the Group’s strategic and organisational objectives.
The Board is supported by an effective corporate governance structure, including the Audit Committee, which has specific 
delegated authority to review the effectiveness of the Group’s internal control mechanisms, financial reporting, internal audit 
and risk management processes.
Executive leadership team
The executive leadership team is responsible for reviewing and managing the strategic risks within the Group and for providing 
oversight on departmental operational risks. It provides leadership and direction to employees on risk-taking activity.
The executive leadership team also has primary responsibility for driving the development and enhancement of the risk 
management processes used within the Group.
Group internal audit
Group internal audit develops and delivers the annual risk-based Group Internal Audit Plan, which is aligned to the strategic 
risks contained within the corporate risk register. This annual plan, which includes a three-year outlook, is approved by the 
Audit Committee.
Group internal audit provides oversight and advice on risks and controls to departmental teams as they manage the risks 
in their areas.
Safety, health, environment and quality (SHEQ) and compliance teams
The SHEQ and compliance teams are responsible for ensuring compliance with codes of practice, such as the Code of Practice 
for Meter Asset Managers and Approved Meter Installers (‘MCoP’) and the Electricity Meter Operations Code of Practice 
Agreement (‘MOCoP’).
The SHEQ team, in conjunction with the executive leadership team and the Board, is instrumental in setting the tone at the top 
in relation to safety matters.
The SHEQ team is responsible for obtaining and maintaining the Group’s ISO certifications, which are supported by business 
assurance reviews.
Departmental management
The management teams in each department within the Group are responsible for the day-to-day management of risks 
within their area, ensuring that risks are appropriately identified, prioritised and mitigated.

Our principal risks are assigned a 
red, amber or green status 
depending on the perceived overall 
severity after allowing for effective 
mitigation. After categorisation, 
risks are treated as follows:
  Some action may be required, 
and risks are routinely monitored 
by management.
  Action is required to mitigate the risk 
through improved control with 
oversight from executive leadership. 
  Mitigating actions are required 
immediately. Oversight is provided 
by the Board, Audit Committee and 
executive leadership directly.

2   Major incident risk
3   Speed of organisational change 
(near term)

disaster recovery 
5   Metering and grid-scale 
batteries supply chain 
6   Funding and working capital 
management 
7   Loss of environmental, social and 
governance (ESG)-related and 
regulatory accreditations 
8   Potential breach of General Data 
Protection Regulation (GDPR) 
9   COVID-19
10   Our people
11   Stability of energy suppliers
All risks are assigned mitigating 
actions with an appropriate 
business owner and are supported 
by an executive sponsor to ensure 
accountability. Our principal risks 
remain unchanged from those 
reported in last year’s Annual report 
and accounts. The risk rating for our 
funding and working capital 
management risk has increased 
from green to amber due to the 
changing macro-economic 
environment. This risk continues 
to be monitored by Board.

2022 is therefore abnormally low, and 
this has resulted in a particularly high 
growth in our earnings per share.
Over the year we continued to invest 
in our established revenue-generating 
carbon reduction (CaRe) assets, 
growing our meter assets and 
developing our portfolio of grid-scale 
battery sites. At the same time, we 
also made smaller but strategic 
investments to develop our capabilities 
in energy data management and electric 
vehicle charging infrastructure. In 2022, 
we in total invested £172.6m net cash in 
investing activities (2021: 121.7m).
We ended the year with net debt of 
£31.2m (31 December 2021: net cash 
£117.7m) and £355m available on our 
debt facility. We are therefore in a 
strong position to continue to deliver our 
meter and grid-scale battery pipelines.

Asset management revenues of 
£92.8m are 12% up on the prior year. 
This growth reflects the flow-through 
effect of progressively increasing the 
rate of meter installations at the end of 
2021 and into 2022 and the annual RPI 
uplift which took effect on 1 April 2022.
Asset installation revenues of 
£30.5m increased 38% on the prior 
year as a result of increased volume 
in transactional meter works and 
increased activity in our connections 
business. 
Energy management revenues of 
£12.2m were up 237% on the prior year. 
This includes £7.2m revenue from our 
grid-scale battery sites which began 
operating in the year. Our first grid-
scale battery site became operational 
in January 2022 and two further sites 
went live in December 2022. Revenue 
from Energy management excluding 
grid-scale batteries was £5.0m, up 38% 
on prior year as a key customer project 
in the hospitality sector picked up 
momentum with the continued recovery 
from the effect of COVID-19 and sector 
focus turning to energy efficiency. 
Gross margins
SMS includes depreciation on revenue-
generating assets within cost of sales 
for statutory reporting purposes. 
Removing this from the gross margin 
provides a better comparison of the 
Group’s underlying trading 
performance year-on-year. 
Depreciation-adjusted gross margin 
for the asset management segment 
is 92% which is in line with prior year 
(2021: 92%).
The asset installation segment gross 
margin was 23% (2021: 32%). In H1 2022 
the Group continued to grow its 
engineering workforce in order to 
support the planned increase in meter 
installations. Costs associated with this 
investment in the workforce such 
as recruitment and training led to 
additional one-off costs which 
depressed the margin in the first half. 
As expected, the margin recovered 
in the second half of 2022.
The energy management segment 
depreciation-adjusted gross margin 
has increased to 57% (2021: 24%). This 
is due to the addition of our grid-scale 
battery sites which generated an 80% 
depreciation-adjusted gross margin 
over the year. Grid-scale batteries 
delivered revenue of £7.2m and 
depreciation adjusted gross profit 
of £5.8m in the year. The gross margin 
on the segment’s other activities 
remained constant at 24% (2021: 24%).
Overall, the depreciation-adjusted 
gross margin at the Group level fell 
by 4% to 73% (2021: 77%) due to the 
investment in our engineer base in 
H1 2022 in our asset installation division 
coupled with the increase in battery 
revenues during 2022.
Pre-exceptional EBITDA
Pre-exceptional EBITDA provides 
a measure of underlying performance 
that is comparable over time. Pre-
exceptional EBITDA of £63.8m was 
21% higher than in the prior year 
(2021: £52.8m).
The £14.5m increase in depreciation-
adjusted gross profit (excluding 
exceptional cost of sales in 2021 
arising from the result of COVID-19) 
was partly offset by a £3.5m increase 
in net operating costs, excluding 
depreciation and amortisation. 
This is being driven by a cost-of-living 
payment made to our employees in 
H2 2022 in response to inflationary 
and other pressures experienced in the 
wider economic environment, further 
investment in our IT and support 
systems and small increases across 
our cost base to support growth in 
other CaRe assets.

Underlying profit before-tax
Depreciation costs on meter assets 
increased 15% to £28.3m (2021: £24.7m) 
due to the increase in the meter asset 
portfolio.
Depreciation cost on grid-scale 
battery sites increased to £1.0m 
(2021: nil) due to the commencement 
of depreciation on operational 
grid-scale battery sites in the year.
Depreciation costs on general 
property, plant and equipment, 
excluding meter assets and grid-scale 
battery sites, has reduced by £0.5m 
to £3.5m (2021: £4.0m) due to some 
computer equipment and fixtures and 
fittings now being fully depreciated. 
Amortisation costs on our intangible 
assets of £4.1m (2021: £4.1m) mainly 
consist of software amortisation 
and were in line with prior year. 
Net finance costs increased £0.4m 
to £3.9m (2021: £3.5m). Finance costs 
relating to our loan facility increased 
£0.7m as we started drawing on the 
facility in the second half, and interest 
on leases also increased £0.5m as 
we leased land for our new grid-scale 
battery sites. The impact was however 
partly offset by £0.3m interest income 
earned.
As a result, underlying profit before 
taxation increased by 34% to £24.5m 
(2021: £18.3m).
Exceptional items
Exceptional items of £6.6m 
(2021: £8.2m) mainly comprise a 
£5.7m loss on the traditional and 
first-generation smart meter 
(‘SMETS1’) portfolio (2021: £5.9m). In 
line with the Group’s established policy, 
these losses are shown separately as 
exceptional items in order to enhance 
disclosure of underlying continuing 
profitability. Acquisition-related costs 
and other exceptional operating items 
amounted to £0.9m (2021: £0.6m). 
Exceptional items in 2021 also included 
£1.7m exceptional finance costs 
comprising the acceleration of 
unamortised arrangement fees 
relating to the Group’s previous loan 
facility which was refinanced in 2021.
Effective tax rate
The Group’s capital expenditure on 
meter assets qualifies for capital 
allowances, providing the Group with 
tax relief on such expenditure. These 
allowances are claimed in the tax year 
in which the asset is acquired and set 
against taxable profit for that year, 
thus reducing the total tax payable. As 
a result, the Group was not tax-paying 
in either the current or prior year. 
The effective tax rate on pre-
exceptional profits for the year is 
11.3% (2021: 39%). This represents the 
announced rate of UK corporation tax 
of 25% from 1 April 2023, which is the 
rate that will apply when the deferred 
tax liability generated by the capital 
allowances unwinds, less the impact 
of c.£2.5m benefit of the tax super-
deduction that has been assessed on 
our qualifying meter assets and grid 
scale battery capital expenditure 
during 2022. The super-deduction 
is only available on qualifying capital 
expenditure until 31 March 2023, 
therefore it is expected that our 
effective tax rate will increase to 
a more normalised level in 2023.
It should also be noted that the 
effective rate on pre-exceptional 
profits in 2021 was high due to a 
change in the deferred tax rate, 
following the UK Government’s 
enactment of the Finance Bill 2021 
in May, which confirmed the increase 
in the rate of corporation tax from 19% 
to 25% from 1 April 2023. This was 
applied to the Group’s brought-
forward deferred tax liabilities on its 
portfolio of meter assets increasing the 
charge in 2021. The full-year effective 
tax rate on 2021 pre-exceptional 
profits excluding the impact of this 
rate change, was 18.5%.
Earnings per share
Underlying basic earnings per share 
(EPS), which excludes exceptional 
items, amortisation of certain 
intangibles and their associated tax 
effect, was 16.06p (2021: 9.60p), 
reflecting the underlying profitability 
of the Group. Statutory earnings per 
share increased to 11.16p (2021: 3.20p). 
As noted above our 2022 tax charge 
also includes the benefit of the tax 
super-deduction available on 
qualifying capital expenditure since 
April 2021. Our effective tax rate for 
2022 is therefore abnormally low, and 
this has resulted in a particularly high 
growth in our earnings per share.
Dividend
A 27.5p per share dividend in respect 
of FY 2021 was approved at the 
Group’s Annual General Meeting in 
May, and the fourth and final instalment 
of this was paid in July 2022.
In line with the Group’s policy to grow 
dividends at 10% per annum, a 30.25p 
per share dividend is proposed in 
respect of FY 2022. This is expected 
to be settled in four equal quarterly 
instalments.

The Board remains comfortable that 
future dividend payment amounts are 
sufficiently secured by long-term, 
sustainable cash flows generated 
from our existing portfolio of metering, 
data and grid-scale battery assets.
Cash flow 
Operating cash inflow in 2022 was 
£63.8m (2021: £61.8m). The cash inflow 
reflects £63.8m pre-exceptional 
EBITDA, £5.5m of non-cash costs 
included in EBITDA and a £4.3m cash 
outflow on working capital net of tax 
receipts, largely due to a deliberate 
build-up of inventory levels to mitigate 
the risk of delays in the supply chain 
and ensure that meters are available 
to grow our installation run rate. 
The Group also drew down £65.0m 
under its loan facility.
The cash generated from operations 
and from our borrowing has been used 
to continue investment in our revenue 
generating meter and grid-scale 
battery assets.
Capital expenditure on property, plant 
and equipment was £143.4m (2021: 
£108.2m). Of this, £105.0m was invested 
in meter and data assets, £36.3m in 
developing grid-scale battery sites 
and £1.1m relates to the purchase of 
land at one of our grid-scale sites. 
Investing activities also include 
payments of £14.6m to acquire battery 
sites (2021: £4.7m) and a further £12.3m 
of instalment payments made for 
grid-scale batteries which have not 
yet been delivered (2021: £nil). On 
the balance sheet, the sites under 
development are classified as assets 
under construction within property, 
plant and equipment and the instalment 
payments for batteries are classified 
as other non-current receivables.
A further £2.2m (2021: £2.8m) investment 
has been made in intangible assets, 
mainly relating to the development 
of software to support the metering 
and installations business.
Investing cash outflows also include 
a £1.4m payment to acquire n3rgy 
and a £2.1m investment (including 
transaction costs) to acquire a 25% 
stake in Clenergy EV Ltd. See note 24 
and note 12 to the consolidated 
financial statements for further details. 
Financial resources
Net debt at 31 December 2022 was 
£31.2m (31 December 2021: Net cash 
£117.7m). This excludes restricted cash 
and lease liabilities accounted for 
under IFRS 16. 
The Group has in place a £420m debt 
facility which matures in December 
2025 and was fully compliant with all 
its bank covenants throughout the 
year. The Group has £32.8m available 
in cash and £355m in unutilised 
facilities (31 December 2021: £420m) 
and therefore continues to have the 
financial flexibility required to 
maximise growth potential in a 
capital-efficient way.

Chairman’s introduction to governance
 “We are firm believers in the 
importance of maintaining 
the highest standards of 
corporate governance.”
Miriam Greenwood
Non-executive Chairman
Dear Shareholder
On behalf of the Board, I am pleased 
to introduce our Corporate governance 
report for this year.
The Board’s focus over 2022 was on 
overseeing the delivery of the Group’s 
strategy to build its base of long-term 
revenue-generating assets and 
develop new carbon reduction (CaRe) 
asset classes. As well as monitoring 
the growth in the Group’s grid-scale 
battery portfolio, the Board approved 
two strategic investments to improve 
the Group’s capabilities in smart 
energy data and electric vehicle 
charging infrastructure.
There were two key changes to the 
Board during the year. Tim Mortlock, 
who had been Chief Operating Officer 
and a full Board member since 2019, 
took over as Chief Executive Officer 
in March 2022. We also welcomed 
Gail Blain to the Board when she took 
over as Chief Financial Officer from 
Gavin Urwin in December 2022. Both 
Tim and Gail have many years’ 
experience with SMS and have been 
central to driving the Group’s strategy.
We are firm believers in the importance 
of maintaining the highest standards 
of corporate governance. We continue 
to adopt the Quoted Companies 
Alliance’s Corporate Governance 
Code (the QCA Code) and I am pleased 
to confirm that the Board has applied 
the principles and complied with all the 
provisions of the QCA Code throughout 
FY 2022. This is set out in our Corporate 
governance report on pages 80 to 89. 
Whilst the Company does not currently 
adopt the UK Corporate Governance 
Code, it endeavours to stay up to date 
with its requirements and continues to 
adopt elements of it, where appropriate. 
I am also delighted that MSCI upgraded 
SMS from A to AA rating in its January 
2023 update to their MSCI ESG Ratings. 
MSCI’s report stated that SMS falls into 
the highest scoring range on corporate 
governance practices, indicating that 
these practices are generally well 
aligned with shareholder interests.
The Board continues to look for ways 
in which it can improve and develop. 
We therefore commissioned an external 
review of the Board’s effectiveness. 
The review concluded that the Board 
was effective and provided independent 
oversight and strong leadership to the 
business. The report raised a number 
of recommendations for further 
improvement which we will be taking 
forward in the coming year. You can 
read more about this in the Nomination 
Committee report on page 96.
Finally, I would like to thank our 
shareholders for their support. I, along 
with the Board, will be available to 
meet with shareholders and respond 
to any questions at our Annual General 
Meeting and I look forward to seeing 
you there.

Overall framework
The Board has a clear corporate governance framework comprising Board-reserved matters, various Committees with their 
terms of reference, and appropriate delegated authorities ensuring decision-making at appropriate levels within the Group.
Corporate governance report
Board of Directors (the ‘Board’)
It is the Board’s role to ensure that the Group is managed 
for the long-term benefit of all its stakeholders, by providing 
effective leadership and direction to the business. It sets the 
Group’s strategy and shapes its purpose. The Group’s culture 
and values are cultivated from the top down, with each Director 
leading by example. The Board is responsible for balanced 
and efficient decision-making, and for overseeing the overall 
financial performance of the Group. Corporate governance is 
a critical component of the Group’s strategy and the Board’s

the business, is vital in the ever-evolving corporate governance 
regime adhered to.
The Company is led by a strong and experienced Board, which 
brings a depth and diversity of expertise to the leadership of 
the Company, essential to support delivery of the Group’s 
strategy over the medium to long term. The Board has an 
appropriate balance of skills, experience and knowledge 
of the Group and its markets to enable it to discharge its 
responsibilities effectively.

the development and implementation 
of those information technology 
projects deemed to be of significant 
importance to the Group. It also acts 
as a forum for consideration of which 
current developments in technology 
have the potential to offer value to 
SMS. The Committee ensures

including those related to the Data 
Protection Act 2018 and, in close liaison 
with the Audit Committee, it ensures 
that information and technology risks 
are identified, assessed and managed 
with actions implemented as 
appropriate. 
The Committee met three times in 
2022. During the year, the Committee

approach to technology, data and 
digital required to support the wider 
business strategy over the next 
three years;

management’s plans to commence 
implementation of a new platform 
to support the ‘Sales to Service’

Roles and responsibilities
The Board members have separate and clearly defined roles and responsibilities, as set out in the table below. 
Each member of the Board has a range of skills and experience that is relevant to the successful operation of the Group. 
Role
Responsibility
Chairman
Responsible for leading the Board and its governance, ensuring the effective 
engagement and contribution of all Non-executive and Executive Directors. 
Ensures that Board meetings take place with a culture of openness and challenge, 
with sufficient time made available to debate the matters tabled. Sets the agenda 
to take full account of the issues and concerns of the Directors and ensures that 
the links between shareholders, the Board and management are strong.
Chief Executive Officer
Responsible for the day-to-day leadership, management and control of the Group, 
across all Group businesses; and for recommending the Group strategy to the 
Board and ensuring that the strategy and decisions of the Board are implemented 
via management. Acts in accordance with the authority delegated from the Board.
Chief Financial Officer
Responsible for the day-to-day financial management and sustainability of the 
Group and for providing general support to the Chief Executive Officer, including 
in relation to the financial and operational performance of the business.
Senior Independent Director
Provides a sounding board for the Chairman, acts as an intermediary for the 
other Directors when necessary and is available to meet with shareholders.
Independent Non-executive 
Directors
Constructively challenge the Executive Directors and monitor the delivery of the 
Group strategy within the risk and control environment set by the Board.
Company Secretary
Supports the Chairman and Chief Executive Officer and is available to all 
Directors for advice and support. Informs the Board and Committees on 
governance matters and is responsible for development.
Independence of the Non-
executive Directors
The Non-executive Directors fulfil a 
vital role in corporate accountability 
and have a particular responsibility to 
ensure that the strategies proposed by 
the Executive Directors are fully 
discussed and critically examined, not 
only to make sure they are in the best 
long-term interests of shareholders, 
but also in order to take account of the 
interests of customers, employees and 
other stakeholders. 
The Board considers each of the 
Non-executive Directors, being Miriam 
Greenwood (Chairman), Graeme 
Bissett, Ruth Leak and Jamie Richards, 
to be independent.
The roles of Chairman and Chief 
Executive Officer are separate and 
there is a clear division of responsibilities 
between the two roles. 
Graeme Bissett is the Senior 
Independent Non-executive Director. 
He is available to shareholders if they 
have concerns which have not been 
resolved via the normal channels of 
Chairman, Chief Executive Officer 
or Chief Financial Officer, or where 
communication through such 
channels would be inappropriate.
Election of Directors
All the Directors are subject to election 
by shareholders at the first Annual 
General Meeting (AGM) after their 
appointment to the Board and, in 
response to shareholder feedback, 
were and shall continue to be subject 
to annual re-election.
Additional appointments
The Chairman and Non-executive 
Directors have other third‑party 
commitments including directorships 
of other companies as set out in their 
biographies. The Company is satisfied 
that these associated commitments 
have no measurable impact on their 
ability to discharge their responsibilities 
effectively. The Executive Directors 
have no third-party commitments.
Independent advice
All Directors are able to take 
independent professional advice in the 
furtherance of their duties, if necessary, 
at the Company’s expense. 
All Directors have access to the advice 
and services of the Company Secretary, 
who is responsible to the Board for 
ensuring that Board procedures are 
followed, and that applicable rules 
and regulations are complied with. 
The appointment and removal of the 
Company Secretary is a matter for the 
Board as a whole. All Directors are 
supplied with information in a timely 
manner in a form, and of a quality, 
appropriate to enable them to 
discharge their duties.
In addition, the Company Secretary 
ensures that the Directors receive 
appropriate training where necessary. 
Regular training is provided on relevant 
topics such as health and safety, AIM 
Rules and the Market Abuse Regulation, 
and these programmes run continuously 
through the year. All Directors are 
encouraged to keep themselves up to 
date with regard to changes in industry, 
practice and regulations and the 
Company continuously assesses its 
training programmes to ensure they 
are relevant and up to date.

How the Board operates
Meetings and attendance
Board meetings are scheduled to be 
held eight times each year. Between 
these meetings, additional Board 
meetings and Board Committee 
meetings may be held as and 
when required. 
Directors are provided with detailed 
and comprehensive papers in advance 
of each Board or Committee meeting, 
and meeting packs are accessed from 
a Board portal. For each scheduled 
Board meeting, the papers include 
updates on financial and operational 
performance together with additional 
papers on specific topics as relevant. 
In 2022, the Board held eight scheduled 
meetings. At each meeting the Board 
received reports from:
•	 the Chief Executive Officer on health 
and safety, strategic, operational and 
business developments, and investor 
relations;
•	 the Chief Financial Officer on the 
financial performance of the 
business: budget, funding and capital; 
and
•	 management on specific topics 
as relevant.
A part of each Board meeting is 
dedicated to the discussion of specific 
strategy matters. Any conflicts of 
interest are declared at the start of 
each Board meeting and appropriate 
action is taken where necessary to 
ensure independent judgement is not 
overridden. A majority of the Board are 
considered independent, which helps to 
address any conflicts of interest that 
may arise. There were no registered 
potential conflicts during 2022. 
The Chairman also holds meetings with 
the Non-executive Directors during the 
year without the Executive Directors 
being present. These meetings provide 
the Non-executive Directors with a 
forum in which to share experiences 
and discuss wider business topics.
The attendance of Directors at scheduled Board and Committee meetings in the year to 31 December 2022 is set out below.

Matters reserved for the Board
The Board is responsible to shareholders 
for the proper management of the 
Group, and has identified key financial

performance of senior management 
to be reviewed and monitored. 
These are set out in a formal schedule 
of matters reserved for the Board,

expenditure or investment projects 
above certain thresholds;

appointments to Board Committees 
and subsidiary boards. 
Responsibility for the development 
of policy and strategy and operational 
management is then delegated to 
the Executive Directors and senior 
management team. 
Board activities
Board activities are structured to 
develop the Group’s strategy and 
to enable the Board to then support 
management on the delivery of the 
strategy within a transparent 
governance framework. The Board 
also regularly discusses governance, 
risk and reputation management, 
and financial performance. 
The Company Secretary is responsible 
to the Board for the timeliness and 
quality of information provided to it. 
The information below is a non-
exhaustive list of the key areas of focus 
for the Board and topics discussed 
during the year to 31 December 2022:
•	 Fit for growth – the Board oversaw 
the preparation and approval of the 
2023 budget and reviewed the Group’s 
updated corporate forecast following 
the budget process. Discussion of 
business development opportunities 
and engagement in evaluating the 
ongoing strategic direction for the 
business remained key focus areas, 
with ongoing review of the Group’s 
investment in grid-scale battery 
storage and exploration of developing 
carbon reduction (‘CaRe’) asset 
classes. The Board reviewed and 
approved the decisions to acquire 
N3rgy and invest in Clenergy EV. 
Following announcement of the 
Group’s ‘net zero by 2030’ target in 
2020, the Board has tracked progress 
against the planned roadmap. 
•	 Performance – at every meeting, the 
Board discussed the Chief Executive 
Officer’s report on performance of 
operations, the Chief Financial 
Officer’s report on financial 
performance, and quarterly market 
metrics. Performance was assessed 
against the approved budget and 
variances understood in the context 
of market and industry developments.
•	 Governance – the Board discussed 
the following: appointment of Tim 
Mortlock as Chief Executive Officer, 
appointment of Gail Blain as Chief 
Financial Officer, full-year preliminary 
results, Annual report and accounts, 
Notice of AGM and dividend 
recommendation, investor site visit

Internal control
The Board has overall responsibility 
for the Group’s system of internal 
control and risk management and 
for reviewing the effectiveness of this 
system. It is supported in this work by 
the Audit Committee, which reviews 
the effectiveness of the Group’s risk 
process and internal control systems. 
Such systems can only be designed 
to manage, rather than eliminate, 
the risk of failure to achieve business 
objectives and can therefore only 
provide reasonable and not absolute 
assurance against material 
misstatement or loss.
Business performance is regularly 
reviewed by the Board through the 
monitoring of:
•	 progress towards strategic 
objectives;
•	 the Group’s financial performance, 
including budgeting and forecasting, 
financial reporting, analysis of 
variances against plan and the taking 
of appropriate management action;
•	 capital investment; and
•	 principal risks and the process by 
which these are evaluated and 
managed on a continuous basis. 
The Board has reviewed the 
effectiveness of the Group’s risk 
management and internal control 
systems, including financial, operational 
and compliance controls. A robust 
assessment of the principal risks faced 
by the Group has also been undertaken.
Board review
Each year, the Company 
carries out a review of the 
Board’s operations, its 
Committees and individual 
Directors. This process gives 
the Directors the opportunity 
to identify areas for improvement 
both jointly and individually.
As part of reviewing the Board, 
the Senior Independent Director 
also leads an assessment of the 
Chairman’s performance. 
FY 2022 Board evaluation
For 2022 the Board 
commissioned an external review 
by an independent consultant, 
Satori. Details of this review are 
given in the Nomination 
Committee report on page 97.

Strategic report

Engaging with our stakeholders strengthens our relationships and helps the business 
make better decisions, which enable it to deliver on its commitments. 
Much of the day-to-day decision-making and stakeholder engagement is carried out at a business level. Further 
details are set out on pages 38 to 41. The Board is regularly updated on wider stakeholder engagement by the Executive 
Directors and via the reports it receives from senior management in the Board and Committee papers, allowing Board 
members to stay abreast of the topics that matter most to stakeholders and to the business. This enables the Board 
to understand and consider these issues in its decision-making. We explain here how, during the year, the Board 
engaged with our stakeholders. 
Material matters requiring the Board’s consideration are outlined on page 37.
Corporate governance report continued
How the Board engages with stakeholders
Suppliers
Lenders/
financiers
Government and 
regulatory bodies
Supplier information is typically 
reported to the Board by exception, 
upon the specific request of one or 
more Board members or concurrent 
with a significant event or change. 
All material supply contracts also 
require Board approval. 
Through regular financial reporting, 
the Board receives information 
about the Group’s revolving credit 
facility and our compliance with key 
covenants. The Chief Financial 
Officer reviews and approves 
quarterly reports that are issued 
to the Group’s lending agent in 
accordance with the terms of the 
Group’s facility. 
During the year, both Executive 
Directors participated in meetings 
with the Group’s syndicate of banks 
to provide an update on the 2022 
budget and performance, and 
discuss the Group’s growth 
strategy. This direct engagement 
promotes an open and transparent 
relationship, which is key in 
supporting the continued growth 
of the business. 
The Board receives information 
about the Company’s regulatory 
and technical compliance, including 
progress on the UK smart meter 
rollout and the first-generation 
smart meter (‘SMETS1’) Enrolment 
and Adoption programme, as part 
of its regular operational reporting.

The Board receives updates from the 
Head of Investor Relations where 
relevant and appropriate, providing 
an overview of market sentiment, 
share price performance and key 
meetings held with investors. 
The Chairman hosted meetings 
with major shareholders in 2022 
to provide a general update on the 
business. Such meetings provide 
a more open line of engagement 
between Board members and key 
investors and it is intended that these 
will take place on a regular basis. 
On 4 October 2022, the Chief 
Executive Officer hosted a 
presentation and site visit for investors 
to our first operational grid-scale 
battery facility at Burwell. The wider 
Board was extensively involved in 
the preparation process for this 
event, reviewing and advising on 
the presentation and supporting 
script. The event was very well 
received and gave investors much 
greater insight into this important new 
asset class for the Group. See page 38 
for more details on the event. 
The Board and management 
regularly receive and respond to 
queries from shareholders on a wide 
range of ESG topics. During the year, 
the views of investors helped inform 
the Board’s decisions on certain ESG 
developments, including the 
incorporation of various best 
practices in further defining the 
Group’s ESG framework such as 
commencing a review of our EU 
Taxonomy alignment and enhancing 
disclosure of our ESG credentials.
The AGM is also an important 
opportunity for the Board to 
share directly with shareholders 
the performance and strategic 
direction of the Company. See 
further details in the section 
entitled The Board’s relationship 
with shareholders on page 89.
Most of the Company’s 
engagement with customers is at 
the operational level. The Chief 
Executive Officer holds regular calls 
with senior representatives of our 
largest customer accounts, as part 
of overall contract governance and 
monitoring. The Board receives 
regular updates from the Chief 
Executive Officer and the senior 
management team on sales and 
service delivery. The Board also 
reviews material customer 
contracts prior to finalisation. 
Over the year, the Board monitored 
the impact of the rises in energy 
costs, inflation and interest rates on 
the Group’s customers. The Chief 
Financial Officer provided regular 
updates to the Board on the status 
of the Group’s customer debt at risk 
of non-collection, and subsequent 
potential impact on net profit.
The Board closely monitors and 
reviews the results of the Group’s 
employee engagement activity, 
as well as any other feedback it 
receives, to ensure alignment 
of interests. 
During the year, the Remuneration 
Committee received an update on 
gender pay reporting. The results of 
the 2022 Best Companies external 
employee engagement survey were 
shared and the proposed action 
plan, together with progress made 
on actions following the 2021 
survey, were discussed.
The Board Committee meetings 
also provide an opportunity for 
employee engagement, with 
attendance by senior employees 
to present updates, host discussion 
and obtain feedback to share with 
the business.

The Board’s relationship 
with shareholders
The Board recognises the importance 
of maintaining open, transparent 
and two-way communication with 
shareholders. This ensures a mutual 
understanding of objectives: for 
shareholders to understand the 
Group’s strategy, and for the Board 
to be aware of shareholders’ feedback 
and any issues raised. 
During 2022 the Executive Directors, 
assisted by the investor relations team, 
attended several meetings, conferences 
and roadshows to maintain regular 
communication with both institutional 
and private investors. The feedback 
from such investor engagement was 
regularly reported to the Board. 
The Group’s Non-executive Directors 
have also been available to meet 
shareholders should they wish to raise 
issues. During the year, the Group 
Chairman and the Chief Executive 
Officer met with major shareholders. 
A variety of topics were discussed. 
The Board receives regular updates 
from the investor relations team, Chief 
Executive Officer and Chief Financial 
Officer on shareholder engagement. 
These updates include share price 
performance, composition of the 
shareholder register, key topics of 
discussion with shareholders, peer 
group comparison, and feedback from 
analyst reports and from brokers and 
public relations partners. 
On the day of interim and full-year 
results announcements, equity 
research analysts are invited to attend 
management’s presentation, which 
is followed by a question-and-answer 
session addressed by the Chief 
Executive Officer and Chief Financial 
Officer. One-to-one and group 
meetings are then held with existing 
institutional shareholders and potential 
new investors.

Group’s website also provides a full 
spectrum of history, news, business 
developments and investor relations 
topics, including a repository of past 
presentations and announcements. 
We will continue to disclose information 
appropriately to satisfy the needs of 
shareholders and investors, thereby 
enhancing understanding of our 
business.
Annual General Meeting
The 2022 AGM will be held in May 2023 
in Glasgow. Full information will be 
provided in the Notice of AGM, to 
be posted separately to shareholders, 
and will be available to download 
from the Company’s website at 
www.sms-plc.com/investors/
shareholder-information.
The AGM is an important forum for 
shareholders, particularly private 
shareholders, to hear more about the 
general development of the business. 
The Chairman and the Chairs of the Audit 
and Remuneration Committees will be 
present at the AGM, giving shareholders 
an opportunity to ask questions, engage 
with members of the Board and learn 
more about the Company. 
The Chairman is also available to 
answer questions throughout the year, 
upon request by investors. If investors 
have any matters that they wish to 
raise outside the forum of the AGM this 
can be done using the contact details 
on the Group’s website.
Other matters
Promoting an ethical 
corporate culture
Various indicators are used to monitor 
and provide insight into the Group’s 
culture, including employee engagement, 
health, safety and wellbeing measures 
and diversity indicators. See pages 
51 to 59 for further details. The Group’s 
culture is assessed through compliance 
reviews, internal audits and the 
provision of formal and informal 
channels for employees to speak up, 
including a whistleblowing hotline that 
allows employees to make disclosures 
in confidence. The Company ensures 
action is taken to address behaviour 
that falls short of the Company’s 
expectations. The Board believes 
that in a business like the Group, 
which is growing rapidly both in 
employee numbers and size of 
operations, a mix of informal and 
formal channels provides a fast and 
robust process to address matters 
raised by the workforce. 
If Directors have concerns about 
the operation of the Board or the 
management of the Company that 
cannot be resolved, their concerns are 
recorded in the minutes of the Board 
meetings. On his or her resignation, a 
Non-executive Director also has the 
opportunity to provide a written 
statement to the Chairman, for 
circulation to the Board, if he or she 
has any concerns about the operation 
of the Board or the management. 
Whistleblowing 
The Group encourages staff to report 
any concerns which they feel need to be 
brought to the attention of management 
concerning any possible impropriety, 
financial or otherwise. The Group has 
put in place a whistleblowing procedure 
where employees can confidentially 
report any concerns or wrongdoing. 
This procedure may be used to report 
incidents of fraud, bribery and 
corruption, discrimination, bullying or 
harassment, and any environmental 
concerns or breaches of the Group’s 
health and safety or quality compliance. 
The Group provides the Audit 
Committee with information in relation 
to matters reported, any subsequent 
investigation and follow-up actions. 
All issues raised are fully investigated 
and appropriate action taken.
There were two whistleblowing 
reports made in the year ended 
31 December 2022, and both instances 
were investigated by our General 
Counsel. One report was found to 
have no substance, while the other 
report was substantiated and senior 
management took appropriate action 
to rectify the situation.
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 on pages 1 to 75. The financial 
position of the Group, its cash flows, 
liquidity position and borrowing 
facilities are described in the Financial 
review on pages 70 to 75. 
The Directors confirm that, having 
considered various scenarios of future 
performance and forecast capital 
expenditure, they are satisfied that the 
Company and the Group have 
adequate resources to continue in 
business for the foreseeable future (for 
the period from the balance sheet date 
to 31 December 2024). For this reason, 
they consider it appropriate to adopt 
the going concern basis in preparing 
the financial statements.

Audit Committee membership
The Committee comprises all the 
independent Non-executive Directors. 
It was chaired during the year under 
review by Graeme Bissett, who is a 
Chartered Accountant with recent and 
relevant financial experience. Jamie

who served during the year are all 
deemed to have the necessary ability 
and experience to understand financial 
statements. 
The Committee meets at least three 
times a year, generally just prior to 
Board meetings, to facilitate immediate 
and efficient reporting to the Board, 
with additional meetings where 
necessary. The external auditor, the 
Head of Internal Audit, the Chief 
Executive Officer and the Chief Financial 
Officer attend Committee meetings by 
invitation. The Committee also meets 
privately with the external auditor 
without management being present. 
The Chairman of the Committee 
maintains a regular dialogue with the

Objectives and 
responsibilities
The Committee’s key objectives are: 
to provide effective governance over 
the Group’s financial reporting and the 
performance of the external auditor; 
to provide oversight of the Group’s 
systems of internal financial control; and 
to report to the Board on these matters. 
In fulfilment of these objectives the 
Committee:
•	 reviews the effectiveness of the 
Group’s internal financial, operational 
and compliance controls and risk 
management processes, including 
arrangements for employees to raise 
concerns (in confidence);
•	 reviews the annual internal audit 
programme and considers the 
findings of any internal investigations 
and management’s response;
•	 reviews SMS’s financial statements 
and announcements and considers 
whether these statements and 
announcements provide a fair, 
balanced and understandable view 
of the strategy, business model and 
performance of the Group and of the 
associated risks;
•	 considers the appropriateness of 
accounting policies and significant 
accounting judgements and the 
disclosure of these in the financial 
statements; and
•	 recommends the appointment of the 
external auditor, approves their 
remuneration and oversees their work 
and overall effectiveness, including 
their relationship with management.
Internal control and 
risk management
The Committee has primary 
responsibility for the oversight of 
the Group’s internal control, including 
the risk management framework 
and the work of the Group internal 
audit function.
The Group has in place an internal 
control environment to protect the 
business from the material risks which 
have been identified. Policies and 
procedures, including clearly defined 
levels of delegated authority, are 
clearly communicated across the 
Group. Management is responsible for 
establishing and maintaining adequate 
internal controls and the Committee 
has responsibility for monitoring the 
effectiveness of these controls. It 
achieves this through reports received 
from the Company and from both the 
internal and external auditors. 
Risk registers are maintained and 
regularly reviewed by management. 
The Board, including the Audit 
Committee, considers the principal 
risks, the nature and extent of the 
Company’s risk management 
framework and the risk profile that 
is acceptable in order to achieve the 
Company’s strategic objectives.
The Group’s system of internal control 
is designed to manage, rather than 
eliminate, the risk of failure to achieve 
business objectives, and it must be 
recognised that it can only provide 
reasonable and not absolute assurance 
against material misstatement or loss.
During the year, the Committee did 
not identify, nor was it advised of, any 
failings or weaknesses in the internal 
control systems or risk management 
processes that were determined to 
be significant.
Whistleblowing
The Board has overall responsibility for 
monitoring the Group’s whistleblowing 
arrangements. It has delegated this to 
the Committee, which updates the 
Board on a regular basis on all 
significant whistleblowing matters 
raised. The Committee receives 
reporting by exception when there 
has been a whistleblowing case raised 
to a line manager, the Group General 
Counsel or through the Group’s 
independent whistleblowing hotline. 
There were two whistleblowing 
reports made in the year ended 
31 December 2022, and both 
instances were investigated by our 
General Counsel. One report was 
found to have no substance, while the 
other report was substantiated and 
senior management took appropriate 
action to rectify the situation.
The Committee is satisfied that the 
Group’s whistleblowing policies and 
procedures, detailed further on page 89, 
are effective, facilitate the independent 
investigation of reported matters and 
allow appropriate follow-up action to 
be taken. 
Internal audit
The Group internal audit function is 
independent and objective and its role, 
as defined in the Internal Audit Charter, 
is to add value and improve the 
organisation’s operations and controls. 
The Head of Internal Audit reports 
functionally to the Audit Committee 
and administratively to the executive 
leadership team. The Chair of the Audit 
Committee meets with the Head of 
Internal Audit periodically without 
executive management present to 
set annual objectives and discuss any 
significant or emerging issues. Group 
internal audit uses a risk-based 
approach to conduct several strategic 
and operational audits throughout the 
year and these are reported and 
discussed at each Audit Committee 
meeting. Monitoring the scope, extent 
and effectiveness of the Group’s internal 
audit activities is an agenda item at each 
Committee meeting. Group internal audit 
is also responsible for confirming that 
management actions and improvement 
points raised within each audit report 
have been implemented effectively and 
in a timely manner. 
Throughout 2022, Group internal audit 
worked with the Board, the executive 
leadership team and members of 
management to support the continued 
development of a robust risk 
management framework upon which it 
can place reliance for identifying areas 
of risk to be considered for inclusion in 
the annual Internal Audit Plan. 
A full risk-based annual Internal Audit 
Plan for 2022, which included a three-
year outlook, was reviewed and 
approved by the Committee in 
November 2021. The programme 
focused on addressing several key risk 
areas including cyber security, grid-
scale batteries, post-acquisition 
performance, treasury management, 
payroll, financial controls over billing and 
fixed asset management and disaster 
recovery planning. Reviews were carried 
out, findings reported to the Committee, 
recommendations tracked and their 
close-out monitored. No significant 
weaknesses were identified from the 
reviews undertaken by Group internal 
audit during the reporting period and 
throughout the financial year.

Audit Committee Report continued
Following the commencement of 
trading of our first grid-scale battery 
site, internal audit carried out a review 
of the electricity trading process and 
the associate controls, and of the 
financial reporting of grid-scale 
battery performance. No significant 
weaknesses were identified.
The Internal Audit Plan for 2023 
was approved by the Committee 
in November 2022. 
The Committee has remained in active 
discussion with Group internal audit 
about the existing risks the Group 
faces as it continues to grow, including 
those in relation to carbon reduction 
(‘CaRe’) verticals, the impact of 
industry and regulatory changes, 
systems development and pervasive 
external risks such as cyber and data 
security. See further details in the 
Our principal risks and uncertainties 
section on pages 65 to 69. 
Going concern
The Committee reviewed management’s 
paper on going concern. The Committee 
assessed and challenged the Group’s 
forecasts and cash flow projections, 
including consideration of various 
possible outcomes of future 
performance and forecast capital 
expenditure and the potential impact 
of uncertainties. The Committee also 
considered the Group’s financing 
facilities and future funding plans. Based 
on this, the Committee is satisfied that 
the financial statements should be 
prepared on a going concern basis.
Financial reporting 
The Committee has reviewed with both 
management and the external auditor 
the annual financial statements, focusing 
on: the overall truth and fairness of the 
results and financial position, including 
the clarity of disclosures shown in the 
statements and their compliance with 
best-practice requirements; the 
appropriateness of the accounting 
policies and practices used in arriving 
at those results; the resolution of 
significant accounting judgements or 
of matters raised by the external 
auditor during the course of the annual 
statutory audit; and the quality of the 
Annual report and accounts taken as 
a whole, including disclosures on 
governance, strategy, risks and 
remuneration, and whether it gives 
a fair, balanced and understandable 
picture of the Group.
The Committee also considered the 
use of alternative performance 
measures by the Group, including the 
appropriateness of their current use 
and their disclosure in the financial 
statements and Strategic report. 
Process
In reaching its conclusions the Audit 
Committee considered the thorough 
process in place to create the Annual 
report and accounts 2022, including:
•	 the involvement of the Committee in 
the preparation of the Annual report 
and accounts 2022 which enabled it 
to provide input into the overall 
messages and tone;
•	 the input provided by Group senior 
management and the process of 
review, evaluation and verification 
to ensure balance, accuracy and 
consistency;
•	 the review by the Committee of 
management’s papers on critical 
accounting judgements and 
assumptions, detailing the approach 
taken and conclusions reached;
•	 the opportunity for the Non-
executive Directors to meet the 
external auditor without any 
executive of the Group being present 
via the private sessions of the 
Committee;
•	 review of the external auditor’s report 
on the Annual report and accounts 
2022, presented to the Committee 
prior to final sign-off;
•	 review and consideration of the draft 
Annual report and accounts 2022 in 
advance of the final sign-off; and
•	 the final sign-off process by the Board.

Below are the key considerations the Committee has in mind when assessing these three components:
Fair
Balanced
Understandable
•	 Is the whole story presented?
•	 Is the narrative reporting in 
the front of the Annual report 
and accounts 2022 consistent 
with the reporting in the 
financial statements?
•	 Are the key messages in the 
narrative reporting reflective 
of the financial reporting?
•	 Is there sufficient information 
included to understand the 
underlying performance of 
the Group and its divisions?
•	 Is there a good level of 
consistency between the 
narrative reporting in the 
front and the financial 
reporting in the back and is 
the messaging in each 
consistent when read 
independently of each other?
•	 Does the narrative reporting 
reflect both the positive and 
negative aspects of 
performance?
•	 Are both the statutory and 
alternative performance 
measures explained clearly 
with appropriate prominence?
•	 Are the key judgements 
referred to in the narrative 
reporting and the significant 
issues reported in the Audit 
Committee report consistent 
with the disclosures of key 
estimation uncertainties and 
critical judgements set out in 
the financial statements?
•	 How do the significant issues 
identified compare with the 
risks that the external auditor 
plans to include in its report?
•	 Is there a clear and 
understandable structure 
to the report?
•	 Are the important messages 
highlighted appropriately and 
consistently throughout the 
document?
•	 Is the narrative within the 
Annual report and accounts 
2022 straightforward and 
transparent?
•	 Is the layout clear with good 
linkage throughout?
Fair, balanced and understandable – what does this mean?

Audit Committee Report continued
Significant matters considered in relation to the Annual report and accounts 2022
Significant areas considered by the Committee in relation to the 2022 Financial statements are set out in the below table:
Area of judgement
Matter considered
Action
Appropriateness of 
capitalisation of overheads 
and other expenses within 
meter assets
SMS continues to carry out a significant level of 
in-house installation of meter assets, certain 
costs of which are capitalised and depreciated 
as part of fixed asset depreciation.
The Committee considered management’s 
capitalisation process and the assumptions and 
judgements used when determining which costs 
are directly attributable to bringing the meter 
assets into use and are therefore eligible for 
capitalisation. 
The Committee was satisfied that the costs 
identified by management for capitalisation 
were appropriate, being directly attributable 
labour costs and an appropriate allocation of 
overheads.
Identification of indicators of 
impairment of the meter 
asset portfolio in accordance 
with IAS 36 and assumptions 
applied in determining the 
carrying value of the 
portfolio of meter assets
Due to the uncertainties associated with the 
timing of the domestic smart meter rollout, the 
expected useful life and carrying value of 
traditional meters requires significant 
judgement, as does the level of recoverability 
of termination income. These assumptions are 
used in deriving the depreciation rates applied 
and the impairment calculation performed on 
carrying value.
Several factors are considered in assessing the 
expected pace of the smart meter replacement 
programme, including the number of smart 
meters still to be installed and the churn of assets. 
The Committee considered the judgements 
made by management, including the quantum 
and disclosure of relevant amounts. 
The Committee confirmed with management 
that there have been no changes to accounting 
estimates with regard to meter assets. The 
Committee considered market and UK 
Government developments regarding the smart 
meter rollout and concluded that this was 
reasonable. 
The Committee considered the accounting 
estimates and judgements used to arrive at 
the expected useful economic life of the 
traditional meter assets and their carrying 
value at 31 December 2022. 
Losses on disposal of de-appointed meters 
have been recognised after allowance for 
termination income and, following 
management’s impairment assessment of 
traditional meter assets, no impairment charge 
was recorded at the end of the year. The 
financial statements provide detailed 
commentary on the estimates and judgements 
involved and on the financial effect. The 
Committee considers that the position 
presented in the financial statements provides 
a reasonable view of the carrying value of 
traditional meter assets.
The Committee is satisfied that charges for 
losses on disposal, net of termination income, 
and for impairment of this asset class, should 
be recorded as exceptional items, as this 
classification will assist understanding of the 
performance of the continuing meter estate 
comprising Industrial & Commercial (I&C) meters 
and domestic smart meters (as distinct from the 
effect of discontinued traditional meter assets). 
The Committee is also satisfied that amounts 
arising in relation to the loss of first-generation 
smart meter assets (‘SMETS1’ meter assets) 
should be recorded as exceptional items, on the 
basis that these disposals are attributable to 
the temporary industry transition period. 
Overall, the Committee is satisfied that the 
approach taken by management to review the 
expected useful life and estimate the carrying 
value of meter assets is appropriate and the 
assumptions applied are sensible and supportable.

Climate change
The Audit Committee discussed the 
impact of climate change on the Group. 
These considerations did not have 
a material impact on the financial 
reporting judgements and estimates, 
consistent with the assessment that 
climate change is not expected to 
have a significant impact on the 
Group’s going concern assessment 
to 31 December 2024. Qualitative 
exploration of potential areas of 
concern, including an evaluation of 
climate exposure on our physical 
assets such as offices, warehouses 
and vehicles, has been carried out 
and we have identified areas of 
potential climate-related risk, such 
as extreme weather events which 
could affect our physical locations 
and road-based employees. Overall, 
the risk of climate-related change 
on the Group is considered low.
External auditor
Ernst & Young LLP (EY) has remained in 
place as auditor since 2015, when the 
practice was appointed following a 
formal tender process undertaken by 
the Group for FY 2015. The external 
auditor is required to rotate the audit 
engagement partner every five years. 
Kevin Weston began his appointment 
as engagement partner from FY 2017 
and therefore FY 2021 was his last year. 
A new engagement partner, Paul 
Copland, was appointed with effect 
from FY 2022. 
External auditor appointment, 
independence and effectiveness
The Committee’s primary responsibility 
is to make a recommendation on the 
appointment, reappointment and/or 
removal of the external auditor. The 
Committee considers a number of 
areas when reviewing the external 
auditor appointment, namely the 
auditor’s performance in discharging 
the audit, the scope of the audit and 
terms of engagement, auditor 
independence and objectivity, and 
auditor remuneration. 
Every year, the Committee assesses 
the effectiveness of the audit process 
and the external auditor. In carrying out 
its assessment in 2022 it considered:
•	 feedback from the Chief Financial 
Officer and her team, who monitor 
the external auditor’s performance, 
behaviour and effectiveness during 
the exercise of its duties;
•	 all key external auditor plans and 
reports, which were discussed and 
challenged;
•	 the regular engagement with the 
external auditor during Committee 
meetings and ad-hoc meetings, 
including meetings without any 
member of management being 
present;
•	 how the auditors support the work 
of the Committee and how the audit 
contributes insights and adds value;
•	 the Committee Chair’s discussions 
with the Senior Statutory Auditor 
ahead of each Committee meeting; 
and
•	 the independence and objectivity 
of the external auditor.
The Committee also reviewed the 
proposed audit fee and terms of 
engagement for FY 2022. Details of the 
fees paid to the external auditor during 
the financial year can be found in note 3 
to the financial statements.
The Committee recognises that the 
independence of the external auditor 
is an essential part of the audit 
framework and the assurance that it 
provides. The external auditor confirms 
its independence at least annually. As a 
matter of principle, the Group’s auditor 
is not engaged for non-audit services, 
thus ensuring that its independence 
and objectivity are not impaired. 
Having completed this review, the 
Committee concluded that the audit 
process, independence and quality of 
the external auditor was satisfactory, 
and has recommended to the Board 
that EY be reappointed as the 
Company’s auditor for FY 2023. 
Accordingly, a resolution proposing 
EY’s reappointment will be tabled 
at the forthcoming Annual General 
Meeting.

Nomination Committee Report
Nomination Committee 
membership
The Nomination Committee is currently 
made up of one Executive Director, 
namely the Chief Executive Officer, 
and all the Non‑executive Directors, 
each of whom is independent.
The Committee is chaired by the 
Chairman, unless the matter under 
discussion is his or her own succession. 
Other Directors are invited to attend as 
appropriate and only if they do not have 
a conflict of interest. The Committee is 
also assisted by executive search 
consultants as and when required. 
During 2022, the Committee met on 
two occasions. In addition, several 
informal meetings and discussions 
were held as part of the process to 
appoint a new Chief Executive Officer 
and Chief Financial Officer.
Role of the Committee
Appointments to the Board are the 
responsibility of the full Board, upon the 
recommendation of the Nomination 
Committee and after appropriate 
external search/consultation, bearing 
in mind the Board’s existing balance of 
skills, knowledge and experience, the 
specific role/capability needs identified, 
and with due regard to diversity, including 
gender. Succession plans are regularly 
reviewed by the Committee in order 
to ensure an orderly progression/ 
refreshment of senior management/ 
Board members and maintain an 
appropriate balance of skills, experience 
and diversity both within the Company 
and on the Board.
Succession planning 
An integral part of the work of the 
Nomination Committee is to establish 
and maintain a stable leadership 
framework and to proactively manage 
changes. Ensuring the right leaders are 
in place enables the organisation to 
compete effectively in the marketplace 
and therefore to meet its various 
obligations to its stakeholders. The 
Nominations Committee has managed 
succession programmes for both the 
Board and senior management, 
ensuring that the necessary skills, 
expertise and experience are present.

Early in 2022 Alan Foy, who had 
served on the Board since the listing 
of the Company in 2011, stepped 
down as Chief Executive Officer. 
The Committee oversaw a search 
for a new Chief Executive Officer, and 
we were delighted that Tim Mortlock 
assumed the role ensuring continuity 
and minimising disruption to the 
business. After consideration 
against potential market candidates 
the Committee recommended that 
Tim Mortlock should be appointed 
as Chief Executive Officer and his 
appointment was confirmed on 
1 March 2022.
During October 2022, Gavin Urwin 
informed the Board of his intention 
to resign as Chief Financial Officer. 
As part of the succession strategy 
Gail Blain, then Group Financial 
Controller, had been identified as 
the natural successor to Gavin Urwin. 
On the recommendation of the 
Nomination Committee after assessing 
other potential candidates in the 
market, Gail Blain was appointed as 
Chief Financial Officer and joined the 
Board on 1 December 2022. Gail has 
a wealth of experience, has been at 
the heart of SMS’s financial strategy 
and has played a pivotal role in 
delivering the Group's strategy 
over the past six years.
In readiness for the ninth anniversaries 
of appointments to the Board, the 
Committee has started the search to 
identify my successor as Chairman (and 
Chair of the Nominations Committee) 
and a successor for the Audit Committee 
Chair. The Nominations Committee has 
engaged Russell Reynolds to conduct 
the external search. The Committee 
requested that a diverse long-list of 
candidates, in respect of gender, 
ethnicity and background, be produced. 
Board inclusion and diversity
The Nomination Committee focuses 
on the leadership required for SMS 
to fulfil its purpose, achieve its vision 
and execute its strategy. This requires 
a clear focus on inclusion and diversity 
to maximise the skills and capabilities 
from which SMS can benefit. Our policy 
is to have a broad range of skills, 
backgrounds and experience on 
the Board. 
Alongside the Board, the Committee 
continues to champion the benefits 
of diversity, be it religious, ethnic or 
gender diversity, or diversity of social 
backgrounds or cognitive and personal 
strengths at Board, Committee and 
senior management level. We are 
pleased that half of the Board of 
Directors of SMS are female, but we 
are aware that gender representation 
is not the only means by which a board 
achieves diversity. We also understand 
the need to improve gender, racial and 
other imbalances throughout our 
organisation, but particularly in senior 
leadership roles. Appointments are 
always based on merit and we continue 
to challenge our external search 
consultants where necessary, to ensure 
that diversity is always considered 
when drawing up candidate shortlists.
The Nomination Committee 
recognises the importance of having 
complementary and diverse skills 
and backgrounds within the Board, 
enabling rich and effective discussions 
and decision-making. The Committee 
continuously reviews the Board 
composition against a skills matrix 
to ensure that the Board and its 
Committees have and maintain the 
skills needed to deliver the Group’s 
strategic priorities.
Board evaluation 
For the three years prior to this reporting 
period, we have carried out internal 
reviews of the Board’s effectiveness. 
This year we commissioned an external 
review by an independent consultant, 
Satori. Other than carrying out this 
evaluation, Satori have no connection 
with SMS. The Chair provided a 
comprehensive brief to Satori and the 
review was undertaken in Quarter 3 2022. 
Satori had access to a number of Board 
and Committee papers during 2022 and 
observed the November Board and 
Committee meetings. Individual 
interviews were conducted with all Board 
Directors and the Company Secretary. 
A report was prepared by Satori with 
final results and recommendations being 
presented to the Board in February 2023. 
We were pleased Satori felt the Board 
was highly professional and effective, 
with good levels of commitment to the 
success of the business and its people, 
and with an open, honest and 
collaborative dynamic. 
The report observed that the Board 
was providing good leadership and 
support to the business, noting there 
was clarity and alignment on the role 
of the Board and of the immediate 
strategic priorities. The decision-
making processes work well and Board 
processes are effective, efficient and 
thorough. The Board Committees also 
worked well. Based on Satori’s review, 
the Board agreed a number of forward-
looking areas for focus and action 
which will further support our continuous 
development. These include: 
•	 considering a five-year board 
development plan linked directly 
to forward strategy;
•	 enhancing the Board view of ‘what 
good to great’ means and identifying 
any metrics to enable this; and
•	 continually reviewing structures to 
stimulate contact between the 
Board and the wider organisation.

Remuneration Committee Report
Introduction by Jamie 
Richards, Remuneration 
Committee Chair
On behalf of the Board and the 
Remuneration Committee, I am pleased 
to present the Remuneration Committee 
Report (the Report) for the financial 
year ended 31 December 2022. This 
report includes my annual statement, 
the directors’ remuneration policy 
(the Policy) and our annual report on 
remuneration. As no changes are 
proposed to the existing Policy, only 
one remuneration resolution will be 
tabled at the AGM in May 2023, 
namely the advisory shareholder 
vote on the Directors’ Annual report 
on remuneration.
The aim of the Remuneration 
Committee 
The Remuneration Committee is 
committed to structuring Executive 
remuneration that is competitive, 
that incentivises and rewards good 
performance, and that will support the 
Group’s growth and ambitions, thereby 
creating value for shareholders. In 
addition, the Committee reviews and 
considers remuneration of the wider 
workforce and monitors related policies, 
satisfying itself that incentives and 
rewards are aligned with the Group’s 
strategy and culture. The Remuneration 
Committee is appointed by the Board 
and comprises four independent 
Non-executive Directors.
Our approach to 
remuneration 
The Remuneration policy is designed to: 
•	 include a competitive mix of base 
pay and both short and long-term 
incentives, with an appropriate 
proportion of the package 
determined by stretching targets 
linked to the Group’s performance;
•	 promote the long-term success of the 
Group, in line with our strategy and 
focus on growth and shareholder 
value; and
•	 provide appropriate alignment 
between the interests of shareholders 
and executives and, where 
appropriate, the wider workforce.

Aligning remuneration 
to Group strategy
The Group’s ongoing vision is to be 
at the heart of the low-carbon, smart 
energy revolution. Our remuneration 
arrangements are designed to support 
management in its growth plan and 
strategy, and to enable the Group to 
be flexible and agile, considering the 
fast pace of our growth in a normal 
trading environment. 
Remuneration Policy 
during the year 
At the 2022 AGM the Committee put 
forward our Directors’ Remuneration 
Policy (the ‘Policy’) to shareholders. 
The Policy was largely based on the 
same principles as the previous 
Directors’ Remuneration Policy; 
however, the Committee made a 
number of changes to align with best 
practice. We were pleased that over 
92% of shareholders voted in support 
of the Policy and the Committee believes 
it remains appropriate in supporting 
the Company’s execution of its strategy 
and long-term shareholder value 
creation. The Committee is confident 
that there continues to be a strong link 
between the Remuneration Policy and 
the business strategy.
Annual bonus for the year 
ended 31 December 2022 
During FY 2022 trading was above 
our expectations and our Executive 
team has performed extremely well, 
ensuring that the Group is well 
positioned to take advantage of 
opportunities. Our Group results in 
FY 2022 were very strong, with 
underlying profit before tax of £24.5m, 
representing growth of 34%, ILARR 
increasing by 13% year on year and 
over 480,000 smart meter installations. 
In a turbulent market, delivering this 
growth across all our key metrics 
reaffirms the Group’s strategy and 
the continued efforts by the Executive 
team to build a long-term, sustainable, 
and successful business. This strong 
performance is reflected in the 
outcome of the annual bonus plan. 
Remuneration Policy for the 
year ending 31 December 2023
The Remuneration Committee is 
aware of ongoing developments 
in corporate governance and best 
practice in executive remuneration, 
and will continually review its executive 
remuneration arrangements to align 
with these where appropriate for 
the business. 
The Remuneration Policy is set out 
on pages 103 to 109 and details of 
how this Policy will be implemented 
for the financial year ahead is set 
out on page 102. 
I hope that you will find this report 
helpful and informative and agree 
that the determinations made by the 
Committee are appropriate and in the 
long-term interests of the Group, its 
employees and our shareholders. I look 
forward to your support at our AGM in 
May 2023 and encourage you to submit 
any questions you may have regarding 
the work of the Committee in advance.

Policy
At the start of 2022 the Committee 
undertook a thorough review of 
all elements of the Executives’ 
remuneration package, including 
base salary, pension, annual bonus 
and wider benefits. The review was 
fully informed by independent advice. 
At the 2022 AGM shareholders approved 
the new Remuneration Policy, which 
is intended to apply for three years 
from that date. There was widespread 
support, as evidenced by over 92% 
voting in favour. This reinforces our 
view that our Remuneration Policy 
continues to reflect our business 
strategy, with remuneration payments 
that are strongly linked to performance. 
Fixed elements of the remuneration 
packages are set so that they reflect 
the calibre and experience of the 
individuals and the complexity of their 
roles. The annual bonus measures are 
based on specific areas that require 
immediate focus, whereas our long-
term incentive plan (LTIP) looks to drive 
sustainable improvements at a more 
macro level over the longer term. 
Culturally, the setting of both financial 
and broader non-financial measures 
serves to focus Executives on a more 
holistic view of business success and 
hence serves to drive performance on 
a broad, sustainable front.
The main changes to the Policy are 
summarised below and were applied 
during FY 2022.
Long-term incentive plan (LTIP)
The LTIP is structured in the form 
of annual awards of nil-cost options 
to the Company’s senior employees. 
Maximum opportunity levels are 
aligned to the market, at 175% of base 
salary for the CEO and 150% of base 
salary for the CFO. All awards will be 
satisfied within a 10% dilution limit 
within any rolling ten-year period. 
The awards will be subject to stretching 
financial and non-financial performance 
targets, measured over a three-year 
period, with phased vesting over 
an overall five-year term in line with 
market best practice and to provide 
further alignment with shareholders. 
Performance measures for the awards 
granted in 2022 were incremental 
EBITDA growth, delivery of absolute 
shareholder return, and ESG measures 
which are core to SMS’s strategy, 
including health and safety and 
progress against our net zero targets. 
Annual bonus
Alongside the introduction of the 
long-term incentive plan, the 
Committee revised the annual bonus 
to align the terms with appropriate 
market benchmarks. The maximum 
bonus opportunity increased from 
100% to 150% for the CEO and 130% for 
the CFO with this being a maximum of 
100% delivered in cash and the balance 
deferred into shares for a period of two 
years. The same award weighting is 
applied to both elements.
Shareholding guidelines
The Committee introduced a 
shareholding guideline for Executives 
with the CEO being expected to 
maintain a shareholding of 2 times 
salary and the CFO being expected 
to maintain a shareholding of 1.5 times 
salary while they are a Director of the 
Company. Given that both Executive 
Directors are relatively new in post, the 
expectation is that this shareholding 
will be established over five years and 
is expected to apply for a period of one 
year following cessation of employment. 
The guidelines will apply to shares from 
incentive awards vesting from the date 
of adoption of the Policy. 
Remuneration for 
performance in 2022
As set out in detail on pages 70 to 75, 
the Group achieved a strong trading 
performance in 2022, with double digit 
growth in our index-linked annualised 
recurring revenue, supported by the 
480,000 smart meter installations. 
140MW of operational battery sites 
were live by 31 December 2022 with 
operational performance of the sites 
significantly ahead of market 
expectations and a largely secured 
grid-scale battery pipeline with 470MW 
secured and a further 150MW under 
exclusivity. Most importantly, there 
have been no significant health and 
safety incidents in the year, reflecting 
the core priority of the Group to 
provide a safe and secure operating 
environment for all our staff (see pages 
56 to 59 for details). The Committee 
determined that there had been a 
robust link between remuneration 
and performance. 
Base salary
Executive Director salaries were 
subject to an annual review process. 
Following this review at the start of 
2022, the Committee agreed to 
increase the salary of Tim Mortlock 
to £435,000 effective 1 March 2022 
and from 1 April 2022 Gavin Urwin’s 
salary increased to £300,000 to align 
with market benchmarking. Gail Blain 
was awarded the same salary as 
Gavin Urwin when appointed as CFO 
from 1 December 2022.
Annual bonus
The targets for the 2022 annual bonus 
for Executive Directors were set by the 
Committee in January of last year and 
remained unchanged throughout the 
year. The strong and resilient financial 
performance of the Group in 2022 is 
reflected in the 2022 annual bonus 
outcomes; the financial measures, 
underlying profit before tax and ILARR, 
have contributed 40% to the overall 
bonus. Both Executives made good 
progress across all other objectives, 
as detailed on page 111; however the 
CEO has received a slightly lower bonus 
percentage compared to the CFO, 
Remuneration Committee Report continued
Annual statement from the Chair of the Remuneration Committee continued
100 SMS Annual report and accounts 2022

solely due to a specific objective 
in relation to absolute share price 
performance that does not feature 
in the CFO’s objectives. Overall, the 
annual bonuses paid to the CEO and 
CFO were 75% (2021: 82%), and 79% 
(2021: 82%) of the maximum respectively. 
The Committee considered whether 
the formula-driven pay-outs under the 
incentive plans and the resultant total 
remuneration for Directors were 
appropriate, looking at the broader 
context within which the performance 
was delivered. 
Long term incentive plans 
After the new LTIP scheme received 
approval at the AGM, the Committee 
awarded LTIP awards to Executives 
and senior management under the 
plan rules and falling within a 10% 
dilution limit over a rolling ten-year 
period. The LTIP is designed to 
encourage management to focus 
on executing the strategy to position 
SMS at the forefront of delivering 
smart energy solutions and provide the 
flexibility to make the right investments 
at the right time and to discourage the 
use of levers to increase revenue and 
profit in the short-term at the expense 
of long-term shareholder value. Our 
people are also eligible to participate in 
our Sharesave plans which promote 
share ownership by giving employees 
an opportunity to invest in SMS shares.
The Committee assessed performance 
against the annual vesting criteria for 
share options awarded to Executives 
and senior management, under the 
extant Option Plan, noting that the plan 
has now expired for new awards and 
reflecting the Committee’s responsibility 
under the plan rules to exercise discretion 
to ensure a fair outcome for all parties 
including the careful evaluation of 
formulaic components. Similarly to last 
year, the Committee took into account 
a range of critical factors. 
In the context of the plan rules, the 
Committee concluded that for all 
option holders the final and fifth 
tranche of the 2018 awards and the 
third tranche of the 2020 awards would 
vest at 84% of the maximum, with the 
balance of 16% lapsing. The second 
tranche of the 2021 option awards 
would vest in full at 100% in line with 
the annual vesting criteria.
Wider workforce
When setting the Executive Directors’ 
remuneration policy, the Committee 
takes into account the pay and 
conditions of employees more 
generally and, at least once a year, is 
given full details of the remuneration 
policy across the Group, with any 
changes highlighted. While the balance 
of the elements of remuneration may 
differ, there is a consistent overall 
principle that all colleagues should be 
paid competitively against the relevant 
pay benchmark.
Continuing to support our employees 
has been a priority this year, from both 
a wellbeing and financial perspective. 
In April 2022 a pay award was 
implemented for all employees. 
A standard 3% increase was applied 
to employees within four of our career 
bandings (excluding those on the Real 
Living Wage who increased by 10.6%), 
and a reduced 2% increase was 
awarded to employees within the top 
career bandings. All eligible employees 
within the Company also received an 
additional discretionary bonus payment 
for FY 2021. As we moved towards the 
winter months we were acutely aware 
of the continued inflationary pressures 
that society was facing, and we were 
cognisant that our employees would 
be experiencing the same pressure 
of rising daily costs. 
Therefore, a decision was made to 
award a one-off discretionary bonus 
of £500 to all employees within the 
lower three career levels (C, D and E) 
as we understood that employees 
within these career levels were most 
affected by the impact of the increase 
in cost of living. In addition, as an 
accredited Living Wage employer, we 
are committed to ensuring we pay the 
Living Wage as a minimum to our 
employees. From May 2023 the Living 
Wage is due to increase from £9.90 
per hour to £10.90 per hour. To ensure 
that our employees continue to be 
supported during this difficult time, we 
increased our entry-level hourly rate to 
£10.90 per hour as of 1 November 2022. 
Implementing this increase six months 
early helped to show our commitment 
to supporting our employees on 
entry-level salaries during this 
challenging time. 
Executive changes 
At the start of 2022 it was announced 
that Alan Foy would step down from 
the Board as CEO and he ceased to 
be a Director on 1 March 2022. In line 
with the remuneration policy at the 
time, it was agreed that Alan Foy would 
receive his current salary and benefits 
up to 1 March 2022, his 2021 bonus 
award, payment in lieu of notice and 
any vested options due under the 
Group’s Unapproved 2018 and 2021 
Share Option awards. Alan Foy did 
not receive any portion of 2022 bonus 
award.
As announced on 13 October 2022, 
Gavin Urwin stepped down from the 
Board as CFO on 1 December 2022. 
In line with the current Remuneration 
Policy, Gavin Urwin will receive his 
current salary and benefits to 31 March 
2023 and the cash element of the 2022 
bonus. The Committee concluded that 
no bonus should be awarded in shares 
due to this element being designed for 
retention. LTIP’s that were awarded to 
Gavin Urwin during 2022, the first year 
of the scheme, were not accepted and 
so were forfeited.

Policy implementation 
for 2023 
Following careful consideration and 
taking into account information from 
the Company’s remuneration adviser, 
the Committee decided not to increase 
the base salaries for the CEO and CFO 
for 2023. 
The Committee have reviewed the 
performance metrics and for the 
2023 financial year the mix of measures 
for the annual bonus scheme has been 
updated to include an element within 
the core objectives relating to the 
operational battery sites. The 
Committee felt it was important 
to bring this element into the core 
objectives to maintain focus 
and delivery.
The 2023 Executive bonus objectives 
reflect the following features, flexed 
to be appropriate to each individual:
•	 core objectives – KPI’s of underlying 
PBT, ILARR, pipeline targets across 
the material business lines, 
operational battery sites and health 
and safety 
•	 personal financial objectives – 
examples include growth of pipeline 
and appropriate long-term capital 
strategy 
•	 personal non-financial objectives 
specific to individual roles 
The LTIP will continue to be based on 
SMS’s performance over three years 
and subject to a two-year holding 
period post-vesting. For 2023, the 
grant level will be unchanged at 175% 
of base salary for the CEO and 150% 
of base salary for the CFO. It is again 
proposed that the performance 
measures should be pre-exceptional 
EBITDA, TSR and ESG/H&S strategic 
measures. The Committee retains 
discretion to adjust annual bonus 
payments and vested LTIP awards if 
the formula-driven outturn does not 
reflect the broader overall performance 
of the business.
Advisers
PricewaterhouseCoopers (PwC) 
provided advice to the Committee 
on matters relating to Executive 
remuneration, all-employee share 
awards and proposed long-term 
incentive awards. PwC remuneration 
consultants are considered to be 
independent of both the Board and 
each of the Executive and Non-
executive Directors. Their advice is 
considered to be objective and 
independent. PwC is a member of the 
Remuneration Consultants Group and 
the voluntary code of conduct of that 
body is designed to ensure objective 
and independent advice is given to 
remuneration committees.
The Committee operates according to 
its terms of reference which have been 
prepared to comply with relevant 
statutory, regulatory and corporate 
governance requirements and best 
practice. During 2022 the terms of 
reference were reviewed by the 
Committee and updated to reflect 
changes in corporate governance 
requirements and best practice. 
The revised terms of reference are 
available for review on our website 
at www.sms-plc.com. 
The Committee appreciates the 
support received from shareholders 
to date on its executive remuneration 
and governance approach and looks 
forward to this continued support for 
the resolution to approve the Annual 
report on remuneration at the AGM 
in May 2023.
The report has been prepared by the 
Committee and approved by the Board 
of Directors.

The Company welcomes dialogue 
with its shareholders over matters 
of remuneration. The Chairman of 
the Remuneration Committee is 
available for contact with institutional 
investors concerning the approach 
to remuneration.
The Policy will be displayed on the 
Group’s website (www.sms-plc.com), 
in the Investor relations section.
Principles
Considerations within the Policy
Clarity: remuneration arrangements 
should be transparent and promote 
effective engagement with shareholders 
and the workforce.
We clearly communicate our approach to remuneration in this report and in all 
communications with shareholders, providing transparency over our rationale. 
This also allows straightforward engagement with the wider workforce.
Simplicity: remuneration structures should 
avoid complexity and their rationale and 
operation should be easy to understand.
We have structured the Remuneration Policy to be as simple as possible, within the 
confines of ensuring arrangements are in line with the business strategy, create a 
robust link between pay and performance and are designed after consideration of 
investor expectations.
Risk: remuneration arrangements should 
ensure reputational and other risks from 
excessive rewards, and behavioural risks 
that can arise from target-based incentive 
plans, are identified and mitigated.
We mitigate these risks through a carefully designed Policy which includes a balance 
between financial and non-financial bonus metrics, incentives plans that are based on 
long-term performance and the option for the Committee to exercise discretion if 
doing so achieves a fairer outcome taking all stakeholders into account.
Predictability: the range of possible values 
of rewards to individual directors and any 
other limits or discretions should be 
identified and explained at the time of 
approving the policy.
We carefully consider the range of likely performance outcomes for incentive plans 
when setting performance target ranges and at the time of assessment would use 
discretion where necessary if the formulaic result were considered inappropriate.
Proportionality: the link between 
individual awards, the delivery of strategy 
and the long-term performance of the 
Company should be clear. Outcomes 
should not reward poor performance.
The opportunity under incentive plans is based on a proportion of salary with the 
quantum selected to ensure an appropriate link between pay and performance.
The performance conditions applying to the incentives are aligned with the Company’s 
strategy and are reviewed on an annual basis to ensure they continue to work 
effectively.
There are provisions to override the formula-driven outcome of incentive plans 
if necessary to ensure that there is not reward for poor performance and that fairness 
is achieved for all parties.
Alignment to culture: incentive schemes 
should drive behaviours consistent with 
Company purpose, values and strategy.
The annual bonus and LTIP performance measures are based on both financial and 
non-financial metrics aligned with all key aspects of strategy including long-term 
sustainable shareholder value growth, maintaining a focus on our customers and the 
quality of our service and ensuring adherence to wider ESG and H&S responsibilities.

Remuneration Committee Report continued
Directors’ Remuneration Policy (The Policy) continued
Objectives of 
Remuneration Policy
The Company’s Remuneration Policy is 
designed to ensure that the Executive 
Directors and senior management are 
fairly and responsibly rewarded for 
their individual contribution to the 
overall long-term performance of the 
Company, in a manner that ensures 
that the Company is able to attract, 
motivate and retain executives of the 
quality necessary to ensure the success 
and sustainability of the Company. 
The remuneration of Executive 
Directors and senior management 
is structured to ensure that:
•	 the fixed elements of pay, salary, 
pension and benefits are 
benchmarked against comparable 
companies of similar size and 
complexity;
•	 Executive Directors and senior 
management are entitled to both 
short-term and long-term incentives, 
in the form of cash bonuses and share 
interests. Both the short-term and 
long-term incentives are underpinned 
by performance criteria linked to the 
Group’s performance; and
•	 remuneration rewards the 
achievement of specific KPIs which 
include, inter alia, the delivery of 
long-term value to shareholders, 
at all times underpinned by a safe 
operating environment, compliance 
with relevant health and safety 
policies, and outstanding service 
to customers.
In determining the remuneration of 
Executive Directors, the Remuneration 
Committee also ensures that 
remuneration arrangements are:
•	 transparent and measurable;
•	 not excessive, thus mitigating the 
reputational and behavioural risks 
that could arise from strictly target-
based incentive plans; and
•	 aligned to our culture, such that they 
drive behaviours consistent with our 
core values. 
Consideration of employment 
conditions elsewhere in the Group
The Committee actively considers pay 
structures across the wider Group 
when setting policy for Executive 
Directors to ensure that a consistent 
approach to reward is adopted which 
is in line with our values. There is a 
particular focus in relation to any base 
salary review. Overall, compared to 
most employees, the Remuneration 
Policy for Executive Directors is 
weighted more to long-term share-
based incentives. This is to ensure 
that the relatively higher pay levels 
are justifiable internally and externally 
to shareholders by a clear link between 
the long-term value created for 
shareholders and the remuneration 
received by Executives.
Our reward framework across the 
Group is based on a consistent set 
of principles for all: that overall 
remuneration should be competitive 
when compared to similar roles in 
other organisations. Colleague pay is 
therefore determined using the same 
principles as the pay for our Executive 
Directors. All employees of the Group 
are entitled to base salary and 
benefits. The Group also operates a 
pension plan for employees in line with 
local market practice. Annual salary 
reviews for other employees across 
the Company are based on broadly 
consistent principles, taking into 
account Company performance, 
market conditions and salary levels for 
similar roles in comparable companies. 
The Company operates discretionary 
bonus schemes for eligible groups of 
employees under which a bonus is 
payable subject to the achievement 
of appropriate targets. All eligible 
employees may participate in the 
Company’s Share Incentive Plan 
on identical terms.
Decision-making process
The Committee is responsible for 
the determination of the Directors’ 
Remuneration Policy and how it is 
implemented. In addressing this 
responsibility the Committee works 
with management and external 
advisers to develop proposals and 
recommendations. The Committee 
considers the source of information 
presented to it, analyses the detail, 
and ensures that independent 
judgement is exercised when making 
decisions. Information is independently 
verified where there are conflicts of 
interest, and no individual is present 
when their remuneration is being 
discussed.
Incentive plan discretions
The Committee will operate the annual 
bonus plan and LTIP in accordance with 
their respective rules. As part of the rules 
the Committee holds certain discretions 
which are required for an efficient and 
fair operation and administration of 
these plans and which are consistent with 
standard market practice. Any use of the 
discretions would, where relevant, be 
explained in the Annual report on 
remuneration and may, as appropriate, 
be the subject of consultation with the 
Company’s major shareholders.
Service contracts and policy 
on payment for loss of office
It is the Company’s policy to require 
twelve months’ notice for termination of 
employment for Executive Directors to 
be given by either party. The Company’s 
policy is to limit severance payments 
on termination to pre-established 
contractual arrangements. If the 
Company believes it appropriate to 
protect its interests, it may also make 
additional payments in exchange for 
non-compete/non-solicitation or other 
terms which extend beyond those in the 
Director’s contract of employment. The 
Committee has discretion to contribute 
towards outplacement services and 
legal fees for any departing Director 
to the extent it considers appropriate. 
104 SMS Annual report and accounts 2022

Under normal circumstances, 
the Company may terminate the 
employment of an Executive Director 
by making a payment in lieu of notice 
equivalent to basic salary and benefits 
for the notice period at the rate current 
at the date of termination. In case 
of gross misconduct, a provision is 
included in the Executive’s contract 
for immediate dismissal with no 
compensation payable. 
The terms applied to the Executive 
Directors’ LTIP and share options are 
consistent with those applied to all LTIP 
and option holders under the rules of 
the schemes. In relation to the LTIP if an 
employee leaves employment, or is on 
notice to leave, on or before the vesting 
date, the employee will forfeit their 
award. Options are subject to a 
five-year service condition, which 
commences from the grant date of the 
first tranche. The plan rules contain 
provisions for good and bad leavers 
and an Executive Director would only 
retain rights to exercise share options, 
in respect of shares for which 
performance conditions have been 
met at the leaving date, where they are 
deemed a good leaver. There is no 
entitlement to compensation or 
damages for any loss or potential loss 
which may be suffered by reason of 
being or becoming unable to exercise 
an option as a consequence of loss of 
office or employment.
Treatment of annual bonus 
on termination of employment
The Committee has discretion to 
determine that in the event an 
Executive Director leaves the 
Company, bonus payments may 
be paid once performance has 
been measured and on a pro-rated 
basis for the time spent in active 
employment with the Company.
Shareholder views 
The Committee welcomes the views of 
shareholders in respect of pay policy as 
well as those views expressed on behalf 
of shareholders by their respective 
proxy advisers. The Committee 
documents all remuneration-related 
comments made at the Company’s 
AGM and within feedback received 
during consultation with shareholders 
throughout the year. Any feedback 
received is fully considered by the 
Committee and amendments may be 
made to the Remuneration Policy where 
thought necessary. The Committee 
seeks to build an active and productive 
dialogue with investors on developments 
in the remuneration aspects of 
corporate governance generally.
Period for Policy 
The Policy came into effect at the date 
of the 2022 AGM and will apply for a 
period of three years. The Committee is 
satisfied that the Remuneration Policy 
is in the best interests of shareholders 
and does not promote excessive 
risk-taking. The Committee retains 
discretion to make non-significant 
changes to the Policy without reverting 
to shareholders.
Share ownership guidelines 
The Committee have introduced 
a policy of encouraging Executive 
Directors to acquire and retain 
shares in the Company, with the 
objective of further aligning their 
long-term interests with those of other 
shareholders. The CEO will be expected 
to maintain a shareholding of 2 times 
salary and the CFO will be expected 
to maintain a shareholding of 1.5 times 
salary while they are a Director of the 
Company. Shares that count towards 
achieving these guidelines include 
shares beneficially owned by an 
Executive Director or by a connected 
person, as recognised by the Committee, 
deferred bonus shares and share 
options / LTIP awards which have 
vested and so are no longer subject 
to performance conditions but are 
subject to post-vesting deferral 
provisions. Executive Directors are 
expected to build their shareholding 
over a five-year period but are not 
required to make personal share 
purchases if awards do not vest through 
failing to meet performance conditions, 
and so a newly-appointed Director may 
not reach the required level within the 
period, depending on the Company’s 
performance against target over the 
period. In this situation, the Committee 
will review the circumstances and agree 
an appropriate forward plan. The 
Committee retains the discretion to grant 
dispensation from these requirements in 
exceptional circumstances. After ceasing 
employment Executive Directors 
must retain a level of shareholding 
for one year. There is no particular 
requirement for Non-executive Directors 
to hold shares but they are encouraged 
to acquire a holding over time.

Executive Directors’ remuneration
The main components of the Policy for the year ended 31 December 2022, and how they link to and support the Company’s 
business strategy, are summarised below. We do not disclose full details of the operational and personal strategic objectives 
for the Executive Directors, as we consider them to be commercially sensitive.
Our remuneration structure can be summarised as follows:
Fixed  1. Base salary
2. Benefits
3. Pension
Variable  4. Annual bonus
5. Long-term incentive plan
6. Share options
Fixed – 1. Base salary
Purpose and link to strategy
Operation
Link to performance
Base salaries are set to recognise individual 
skill, experience and performance, as well 
as the market value of the role, so as to 
attract, retain and motivate the most 
qualified staff to deliver against our 
strategy and KPIs, implement our business 
model, manage our risks and exploit our 
opportunities, while remaining disciplined 
about fixed cost management.
Salaries are typically reviewed annually, 
and take into account:
Company performance; the scope of the 
role, and the experience and performance 
of the individual Director; average workforce 
salary adjustments within the Company; 
and the size, complexity and growth rate 
of the Company.
Limitation:
Maximum increases are no greater than 
inflation unless: (a) there has been a 
material increase in industry rates; (b) 
changes in role have taken place with 
enhanced responsibility; or (c) there has 
been a reward for individual development.
Base salary is not conditional on 
performance. Any salary increases 
will generally be in line with those 
awarded to salaried employees. 
2023 application
Based on last year’s benchmarking of AIM50 companies and advice from our remuneration adviser, no inflationary increase 
will be awarded to Executive Directors in 2023.
Fixed – 2. Benefits
Purpose and link to strategy
Operation
Link to performance
To complement base salary by providing 
market-competitive benefits to attract 
and retain Executives.
Reviewed from time to time to ensure that 
benefits, when taken together with other 
elements of remuneration, remain 
market-competitive. Benefits include car 
allowance and private medical healthcare. 
Other benefits may be introduced to 
ensure benefits overall are competitive 
and appropriate to the circumstances.
Limitation:
Benefits are set by the Committee 
at levels appropriate for our business 
relative to the market. 
The cost of providing these benefits 
varies year on year depending on the 
schemes’ premiums. The Remuneration 
Committee monitors the overall cost of 
the benefits package.
Benefits are not conditional on 
performance, but we believe they 
enhance recruitment and retention 
of talent and improve staff wellbeing.
106 SMS Annual report and accounts 2022

Fixed – 3. Pension
Purpose and link to strategy
Operation
Link to performance
To provide retirement benefits which, 
when taken together with other elements 
of the remuneration package, will enable 
the Company to attract and retain 
Executives of a high calibre. 
The Executive Directors (together with all 
other eligible staff) are able to participate 
in the Company’s defined contribution 
(money purchase) pension scheme.
Limitation:
Company contributions are based on 
percentage of salary, ranging from the 
statutory minimum to a maximum of 
5% of salary.
Pension contributions are not 
conditional on performance.
Variable – 4. Annual bonus
Purpose and link to strategy
Operation
Link to performance
To reward Executives for achieving key 
financial, operational and strategic annual 
goals, by selecting measures that drive 
long-term shareholder value.
The Executive Directors (together with 
the senior management team) participate 
in a discretionary, annual, performance-
related bonus scheme. Targets are set 
at the beginning of each year based on 
the recommendations of the Remuneration 
Committee.
For 2022 the maximum opportunity was 
equal to 150% of salary for the CEO and 
130% of salary for the CFO, with a 
maximum of 100% being delivered in 
cash and the balance being deferred 
into shares for a period of two years, and 
the same award weighting being applied 
to both elements.
The Committee applies discretion to the 
final bonus payout, taking into account 
performance against targets and 
underlying performance of the Company.
Bonus may be subject to clawback or 
malus being applied, if appropriate, in 
the event of financial misstatement, error, 
misconduct, reputational damage or 
corporate failure, which has led to an 
over-payment.
The Committee determines annual 
metrics based on approved budgets 
and priorities for the forthcoming year. 
The annual bonus is based on three 
weighted areas: core objectives, 
personal financial objectives and 
personal non-financial objectives. 
Performance measures under each 
area are determined annually and the 
Committee is able to adjust the 
weighting of the areas annually based 
on prevailing business needs. 
Targets are considered to be 
commercially sensitive and will be 
disclosed retrospectively following 
completion of the relevant financial year.
2023 application
Core performance measures are the same for both the CEO and CFO and are aligned to the Company’s KPIs of underlying PBT, 
ILARR, operational battery sites and health and safety. The financial element of the bonuses start to be earned for threshold 
performance rising on a straight-line basis to the maximum for exceeding budget performance. 
Personal financial performance measures will vary each year depending on business context and strategy. For 2023, the CEO’s 
are to further grow our battery and meter asset pipeline, develop our sales pipeline and products in developing CaRe products 
and increase our absolute share price performance. The CFO’s personal financial objectives for 2023 are set to ensure the 
business has a clear long-term capital strategy for sound funding of its business growth and operations.
Personal non-financial performance measures focus on leadership, structure, team, culture and behaviour.
For 2023 the maximum opportunity is equal to 150% of salary for the CEO and 130% of salary for the CFO, with a maximum of 100% 
being delivered in cash and the balance being deferred into shares for a period of two years, and the same award weighting being 
applied to both elements.

Variable – 5. Long-term incentive plan (LTIP) 
Purpose and link to strategy
Operation
Link to performance
Incentivises and rewards Executives for 
the delivery of longer-term strategic 
objectives and substantial relative and 
absolute increases in shareholder value.
LTIP awards may be granted each year in 
the form of a conditional award of shares, 
with vested awards released to 
participants in tranches.
Annual awards of nil-cost options over plc 
shares will be granted to participants.
Awards will be subject to a three-year 
performance period.
Subject to the achievement of 
performance targets, the options will then 
vest in tranches after three, four and five 
years subject to continued employment 
until the relevant vesting date (75% on the 
third anniversary of grant, 12.5% on the 
fourth anniversary, and 12.5% on the 
fifth anniversary).
The maximum award is 175% of salary 
for CEO and 150% of salary for CFO. 
The Remuneration Committee will have 
customary discretion rights and the ability 
to override formulaic outcomes in line with 
corporate governance principles to 
achieve fairness to all parties.
All awards will be satisfied within a 
10% dilution limit within any rolling 
ten-year period.
Targets are reviewed annually ahead 
of each grant to ensure they are 
aligned to the business strategy 
and performance outlook.
The majority of the awards will be 
based on financial performance 
and shareholder return.
The Remuneration Committee retains 
discretion in exceptional circumstances 
to change performance measures and 
targets and the weightings attached 
to performance measures part-way 
through a performance period if there 
is a significant and material event 
which causes the Remuneration 
Committee to believe the original 
measures, weightings and targets 
are no longer appropriate. 
Discretion may also be exercised 
in cases where the Remuneration 
Committee believe that the vesting 
outcome is not a fair and accurate 
reflection of business performance. 
2023 application
2023 LTIP awards were approved in March 2023. Performance conditions are consistent with LTIPs that were previously awarded, 
focusing on pre-exceptional EBITDA, TSR and ESG strategic metrics, each applied independently, and there will be a straight-line 
sliding scale between points.

Non-executive Directors fees
Purpose and link to strategy
Operation
Link to performance
To attract and retain Non-executive 
Directors with appropriate skills, 
experience, independence and knowledge 
of the Company and its business.
Fee levels for Non-executive Directors are 
generally reviewed by the Board annually. 
Remuneration comprises an annual fee for 
acting as a Non-executive Director and 
serving as a member of any Committees. 
Additional fees are paid in respect of 
service as Chairman of a Committee or as 
Senior Independent Director. When 
reviewing fees, reference is made to fees 
for the same comparator group as is used 
for Executive Directors, as well as 
information gathered from a number of 
remuneration surveys, and assessment of 
the extent of the duties performed and the 
size of the Company.
None
The remuneration of the Non-executive Directors, including the Chairman, is determined by the Executive Directors after 
external benchmarking. Non-executive Directors and the Chairman do not participate in incentive arrangements or receive 
other remuneration in addition to their fees. 
Each of the Non-executive Directors has a letter of appointment stating their annual fee and that their appointment 
is for a term of three years. Their appointment may be terminated on three months’ written notice at any time. 
During 2022 the Executive Directors approved an increase to the Non-executive Director fees on 1 April 2022. 
No increase to the annual fees of Non-executive Directors will be made in 2023.

1	 Tim Mortlock holds 133,250 share options as part of the 2014 Share Option Plan and 309,333 share options as part of the 2018 Share Option Plan, 
these share options are fully vested and to date have not been exercised.
2	 Gail Blain holds 50,000 share options as part of the 2016 Share Option Plan, and 46,400 share options as part of the 2018 Share Option Plan, 
these share options are fully vested and to date have not been exercised.
The share price at 31 December 2022 was £7.82. The weighted average share price at the date of exercise of options 
exercised during the year ended 31 December 2022 was £8.02 (2021: £8.36).
The plan is structured with options vesting in annual tranches. The vesting of each annual tranche takes place by reference 
to a distinct annual performance period and is subject to annual targets including a market capitalisation target, non-
market performance criteria based on financial targets and individual objectives, which are set at the beginning of the 
corresponding performance period. 
The share options cannot be exercised for a period of five years from the grant date, other than in specific circumstances. 
Tranches which did not vest due to a missed market capitalisation target will subsequently automatically vest in future years 
if the future-year market capitalisation target is met or on the occurrence of certain events which would cause all tranches 
to vest. The Remuneration Committee has discretion in relation to the vesting of awards where certain other criteria are 
not met. The Remuneration Committee additionally has the power to make changes to existing granted share options 
(for example in relation to the option price or number of options granted) where changes are made to the capital structure 
of the Company. 
The vesting outcome of the outstanding 2018 and 2021 options held by the Executive Directors was assessed by the 
Committee as described on page 101. The Committee concluded that the final tranche of the 2018 award would vest at 84% 
of the maximum, with the balance of 16% lapsing. The second tranche of the 2021 option awards would vest in full at 100% in 
line with the annual vesting criteria. The earliest exercisable date is 1 January 2023 for the 2018 options and 1 January 2026 
for the 2021 options.
Further details of LTIPs and options granted by the Company at 31 December 2022 are given in note 28 to the financial 
statements.

The Board will review this regularly, 
with shareholder value in mind and 
taking into account a range of factors. 
These will include expected business 
performance, the Company’s ability to 
continue as a going concern and meet 
its debt obligations, the distributable 
reserves in the parent company, the 
availability of cash resources, the 
dividend and operational cash flow 
cover, future cash commitments and

Employees
Employee involvement and 
communication is paramount to the 
Company’s success. The Group’s policy 
of operating through subsidiaries helps 
ensure close communication and sharing 
of information with employees on 
matters likely to affect their interests. 
In addition, the workforce is kept up 
to date on the various financial and 
economic factors affecting the 
performance of the Group. Periodic 
updates on Group performance are 
circulated, typically following the 
announcement of both interim and 
annual financial results, with a

External auditor
As detailed on page 95, the Audit 
Committee recommended, and the 
Board approved, the proposal that 
the current auditor, Ernst & Young LLP, 
be reappointed as auditor of the 
Company at the AGM. Ernst & Young 
LLP has expressed its willingness to 
continue in office as auditor and a 
resolution to reappoint Ernst & Young 
LLP as the Company’s auditor will 
therefore be proposed to shareholders 
at the AGM.

is no relevant audit information of 
which the Company’s auditor is 
unaware; and 
•	 he or she has taken all the steps that 
ought to be taken by a Director in 
order to make himself or herself aware 
of any relevant audit information and

Going concern 
After making enquiries, we, the Directors, 
have a reasonable expectation that the 
Group has adequate resources to 
continue in operational existence for 
the foreseeable future (for the period 
from the balance sheet date to 
31 December 2024). We therefore 
continue to adopt the going concern 
basis in preparing the financial 
statements. The basis on which this 
conclusion has been reached is set 
out on pages 129 to 130, which is 
incorporated by reference here.
Political contributions
No political contributions were made 
during the year (2021: £nil).
Post balance sheet events
There are no post balance sheet 
events requiring disclosure.
Research and development
The main research and development 
activities relate to IT systems 
development to support the metering 
and installations business. In addition, 
the Group continues to invest in future 
technologies related to decarbonisation 
and energy efficiency.
Share capital
The Company’s issued share capital 
comprises ordinary shares of £0.01 each 
which are listed on AIM, a market 
operated by the London Stock Exchange 
(AIM: SMS.L). As at 31 December 2022, 
the issued share capital of the Company 
was £1,333,970 comprising 133,397,009 
ordinary shares of £0.01 each. 
Details of the issued share capital of 
the Company, together with movements 
in the issued share capital during the 
year, can be found in note 27 to the 
financial statements. All the information 
detailed in note 27 forms part of this 
Directors’ report and is incorporated 
into it by reference. 
The Company was authorised at the 
AGM in May 2022 to allot shares or 
grant rights to or subscribe for or convert 
any security into shares in the Company 
up to a nominal amount of £444,546. This 
aligns with the institutional investor 
guideline recommended figure of an 
amount equal to one-third of the total 
issued share capital. This authority is 
valid for a period expiring five years from 
the date the resolution was approved at 
the 2022 AGM; however, this authority is 
revised on an annual basis at each AGM, 
at which point the previous year’s 
resolution is generally superseded. 
Share Incentive Plan 
The Group’s Share Incentive Plan (SIP) 
is HMRC-approved and is open to all 
qualifying employees, including 
Executive Directors. 
The Partnership Share element 
provides that for every share a 
participant purchases in the Company, 
up to a current maximum contribution 
of £1,800 per year, the Company will 
purchase one Matching Share. The 
Matching Shares purchased are held 
in trust in the name of the individual. 
Dividends received on shares held in 
the SIP are reinvested to acquire 
Matching Shares at their market value. 
There are various rules as to the period 
of time that the shares must be held in 
trust, but after five years the shares can 
be released tax-free to the participant.
Under the terms of this scheme, the 
Matching Shares will be forfeited if the 
participant leaves the employment of 
the Company within three years of the 
award (unless they are classed as a 
‘good leaver’). 
During the year, the Company 
purchased 48,900 of its own shares 
(2021: 34,191) from the market for the 
purpose of satisfying its Matching Share 
obligations under the SIP. The nominal 
value of the shares purchased was 
£489 (2021: £342) and the aggregate 
amount of consideration paid was 
£0.4m (2021: £0.3m).

Governance
Strategic report

The Directors are responsible for preparing the Directors’ 
report, the Strategic report, the Directors’ remuneration 
report, the separate Corporate governance statement 
and the financial statements in accordance with 
applicable law and regulations.
Company law requires the Directors to 
prepare Group and Company financial 
statements for each financial year. The 
Directors are required by the AIM Rules 
of the London Stock Exchange to 
prepare Group financial statements 
in accordance with UK-adopted 
international accounting standards 
(‘IFRSs’), and have elected under 
company law to prepare the Company 
financial statements in accordance with 
United Kingdom Generally Accepted 
Accounting Practice (United Kingdom 
Accounting Standards and applicable 
law), including FRS 102 The Financial 
Reporting Standard Applicable in the 
UK and Republic of Ireland.
The Group financial statements are 
required by law, and by IFRSs, to 
present fairly the financial position 
and performance of the Group; and 
the Companies Act 2006 provides in 
relation to such financial statements 
that references in the relevant part of 
that Act to financial statements giving 
a true and fair view are references to 
their achieving a fair presentation.
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 the Company and of the 
profit or loss of the Group 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 accounting 
estimates that are reasonable;
•	 present information, including 
accounting policies, in a manner that 
provides relevant, reliable, comparable 
and understandable information;
•	 for the Group financial statements, 
state whether they have been 
prepared in accordance with UK-
adopted international accounting 
standards and, for the Company 
financial statements, state whether 
applicable UK accounting standards 
including FRS 102 have been followed, 
subject to any material departures 
disclosed and explained in the 
Company financial statements; and
•	 prepare the financial statements 
on the going concern basis unless 
it is inappropriate to presume that 
the Group and the Company will 
continue in business.
The Directors are responsible for keeping 
adequate accounting records that are 
sufficient to show and explain the 
Group’s and the Company’s transactions 
and disclose with reasonable accuracy 
at any time the financial position of the 
Group and the Company. They are also 
responsible for safeguarding the 
assets of the Group and the Company 
and hence for taking reasonable steps 
for the prevention and detection of 
fraud and other irregularities.
The Directors are responsible for 
the maintenance and integrity of the 
corporate and financial information 
included on the Smart Metering 
Systems plc website. Legislation in 
the UK governing the preparation and 
dissemination of financial statements 
may differ from legislation in other 
jurisdictions.

approved by the Board of Directors 
on 14 March 2023 and signed on its

Independent auditor’s report 
to the Members of Smart Metering Systems plc
Opinion
In our opinion:
•	 Smart Metering Systems plc’s group financial statements and parent company financial statements (the 
“financial statements”) give a true and fair view of the state of the group’s and of the parent company’s affairs 
as at 31 December 2022 and of the group’s profit for the year then ended;
•	 the group financial statements have been properly prepared in accordance with UK adopted international 
accounting standards;
•	 the parent company financial statements have been properly prepared in accordance with United Kingdom 
Generally Accepted Accounting Practice; and
•	 the financial statements have been prepared in accordance with the requirements of the Companies Act 2006.
We have audited the financial statements of Smart Metering Systems plc (the ‘parent company’) and its subsidiaries 
(the ‘group’) for the year ended 31 December 2022 which comprise:

Related notes 1 to 32 to the financial statements, 
including a summary of significant accounting policies
The financial reporting framework that has been applied in the preparation of the group financial statements is applicable 
law and UK adopted international accounting standards. The financial reporting framework that has been applied in the 
preparation of the parent company financial statements is applicable law and United Kingdom Accounting Standards, 
FRS 101 “Reduced Disclosure Framework” (United Kingdom Generally Accepted Accounting Practice).
Basis for opinion 
We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our 
responsibilities under those standards are further described in the Auditor’s responsibilities for the audit of the financial 
statements section of our report. 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 entities, and we have fulfilled our other ethical responsibilities in accordance with these requirements.
We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.
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 close process, we confirmed our understanding of 
management’s going concern assessment process and also engaged with management early to ensure all key factors 
were considered in their assessment.
•	 We obtained management’s going concern assessment, including the cash forecasts and covenant calculations for the 
going concern period ending 31 December 2024. The group has modelled adverse scenarios in their cash forecasts and 
covenant calculations in order to incorporate severe but plausible changes in key assumptions to the forecasted liquidity 
of the group.
•	 We have tested the factors and assumptions included in each modelled scenario for the cash forecast and covenant 
calculation. We have reviewed the facility agreement and confirmed compliance with covenants at the year end and 
that the model show no breach throughout the going concern period. 
118 SMS Annual report and accounts 2022

•	 We also verified credit facilities available to the group to signed agreements with lenders. The group has access to 
committed bank facilities of £420m, which is £65m drawn down as at 31 December 2022. The full amount of these facilities 
matures in 2025.
•	 EY performed reverse stress testing which demonstrated that if there were no new meter installations from 
December 2022, SMS plc could still continue to invest in their planned grid scale capital expenditure. This is not deemed 
a plausible scenario. 
•	 We read the group’s going concern disclosures included in the annual report in order to assess that the disclosures were 
appropriate and in conformity with the reporting standards. 
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 of when the financial statements are authorised for issue until 31 December 2024.
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 four components and audit 
procedures on specific balances for a further twelve components.
The components where we performed full or specific audit procedures accounted for 100% 
of pre-tax profit before exceptional items (our audit testing covers 100% of exceptional items), 
99% of revenue and 97% of total assets.
Key audit matters
Identification of indicators of impairment of the meter asset portfolio in accordance with IAS 36 and 
assumptions applied in determining the carrying value of the portfolio of meter assets if indicators 
are present.
Appropriateness of capitalisation of overheads and other expenses within the total of costs 
capitalised within meter assets. 
Materiality
Overall group materiality of £1.1m which represents 5% of the group’s profit before tax (PBT) before 
exceptional 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, 
the potential impact of climate change, changes in the business environment and other factors such as recent Internal audit 
results when assessing the level of work to be performed at each company.
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 31 reporting components of the Group, 
we selected 16 components covering entities within the UK and Ireland, which represent the principal business units 
within the Group.
Of the 16 components selected, we performed an audit of the complete financial information of 4 components (“full scope 
components”) which were selected based on their size or risk characteristics. For the remaining 12 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. 
The reporting components where we performed audit procedures accounted for 100% (2021: 100%) of the Group’s Profit 
before tax before exceptional items, 99% (2021: 100%) of the Group’s Revenue and 97% (2021: 98%) of the Group’s Total 
assets. For the current year, the full scope components contributed 92% (2021: 92%) of the Group’s Profit before tax before 
exceptional items used to calculate materiality, 89% (2021: 94%) of the Group’s Revenue and 83% (2021: 94%) of the Group’s 
Total assets. The specific scope component contributed 8% (2021: 8%) of the Group’s Profit before tax before exceptional 
items, 10% (2021: 6%) of the Group’s Revenue and 14% (2021: 4%) 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.

Climate change 
There has been increasing interest from stakeholders as to how climate change will impact the group. Given the nature of 
the business management does not consider there to be a material impact from climate change. These considerations are 
explained on page 95 in the Audit Committee Report, which forms part of the “Other information,” rather than the audited 
financial statements. Our procedures on these 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.
As explained in the Basis of Preparation note, climate change risks are still developing, and are interdependent upon 
each other, and consequently financial statements cannot capture all possible future outcomes as these are not yet 
known. The degree of certainty of these changes may also mean that they cannot be taken into account when 
determining asset and liability valuations and the timing of future cash flows under the requirements of UK adopted 
international accounting standards. 
Based on our work we have not identified the impact of climate change on the financial statements to be a key audit matter 
or to impact a key audit matter.

Key audit matters 
Key audit matters are those matters that, in our professional judgment, 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.
Risk
Our response to the risk
Key observations communicated 
to the Audit Committee 
Identification of indicators of 
impairment of the meter asset 
portfolio in accordance with 
IAS 36 and assumptions 
applied in determining the 
carrying value of the portfolio 
of meter assets if impairment 
indicators are present (£430m 
value of risk, PY comparative 
£367m).
Refer to the Audit Committee 
Report (page 94); Accounting 
policies (page 131); and Note 11 
of the Consolidated Financial 
Statements.
i/ Traditional meters
Management prepared an 
assessment of potential 
impairment indicators in 
relation to the traditional 
meter portfolio which indicated 
that there remained significant 
headroom in relation to the 
traditional meter portfolio. 
Management concluded that it 
would not be appropriate to 
recognise a reversal of the 
historical impairment charge 
on consideration of the 
declining nature of the 
portfolio, with the smart meter 
roll out still in place, albeit 
extended to 31 December 
2025, and the uncertainty as to 
whether the rollout period 
changing will have a major 
impact on the behaviour of 
energy suppliers and the 
knock-on impact on 
installation run rates. 
Therefore, management 
conclude that the above noted 
components that triggered the 
impairment, remain prevalent 
in the current year.
We obtained management’s impairment assessment which 
concluded that there are impairment indicators present due to the 
declining nature of the traditional meter portfolio.
We identified controls designed by management to determine the 
appropriateness of the assumptions included within the impairment 
model.
EY reviewed and challenged management’s accounting paper 
assessing if there are impairment indicators in accordance with 
IAS36 for each category of meters. 
We have performed procedures to independently identify potential 
impairment indicators including reviewing publicly available information. 
Management has concluded that there remains no significant risk of 
impairment with regards to the first-generated SMETS1 smart meter, 
as a result of the required Enrolment & Adoption process into the DCC, 
which has seen SMETS1 meters removed from the wall. This process is 
now expected to continue through to the end of 2023 following an 
extension issued by BEIS. It’s anticipated that the removal rate will 
reduce significantly over this period given that ~79% of SMS’ SMETS1 
meters have now enrolled and adopted. We therefore concluded that 
management’s assessment was reasonable.
There were no indicators or impairment or matters of consideration for 
SMETS2 or I&C meters. 
Consistent with management’s assessment, we concur that there 
were impairment indicators in relation to the traditional meter 
portfolio given the smart meter roll out which results in traditional 
meters being removed from the wall. EY have assessed and 
challenged management’s impairment model to corroborate 
management’s conclusion that no impairment is required. This 
included challenging the key assumptions: 
•	The profile of removal of meters from the wall;
•	The recoverability and issuance of termination income for the 
meters remaining on the wall;
•	The expected churn in customers between energy suppliers 
determining the termination income earned;
•	The expected increase in annual rental income in line with RPI as 
defined in the contract
•	The discount rate applied in order to determine the net present 
value of future cashflows. 
•	EY have tested the integrity of the underlying data for the 
customer churn and termination income assumptions. 
We have performed sensitivity testing of the key assumptions.
We have reviewed the disclosures made around the judgements 
management have taken in assessing the indicators of impairment 
within the meter portfolio.
The group team performed full scope audit procedures over this 
risk area, which covered 100% of the risk amount.
Based on the audit procedures 
performed in relation to the 
meter portfolio, we consider 
the year-end carrying value to 
be appropriate. 
In relation to SMETS1 meters, 
until the enrolment and 
adoption programme is 
completed, there may be 
removal of further meters 
which would represent a small 
proportion of the total 
portfolio of meters. We do not 
consider this to represent an 
impairment risk to the wider 
SMETS1 portfolio. 
We consider the disclosures 
made around the traditional 
meter assets to be adequate.

Risk
Our response to the risk
Key observations communicated 
to the Audit Committee 
Appropriateness of 
capitalisation of overheads 
and other expenses within 
the total of costs capitalised 
within meter assets (£430m 
value of total meter assets, 
PY comparative £367m)
Refer to Audit Committee 
Report (page 94); Accounting 
policies (page 131) and note 11 
in the Consolidated Financial 
Statements.
As at 31 December 2022, 
the group carried total meter 
assets amounting to £430m 
(2021: £367m). This includes 
internal operational costs 
that have been capitalised 
in the current year.
A significant proportion of 
the group’s smart meters 
are fitted by its in-house 
engineering team. The costs 
directly attributable to bringing 
the asset to the condition 
and location necessary for 
it to be capable of operating 
in the manner intended by 
management are capitalised 
in line with IAS 16.
The significant risk relates 
to the judgements made by 
management when assessing 
the appropriate categories 
and proportion of direct costs 
of installation, overheads 
and other expenses directly 
attributable to the installation 
of each meter.
We identified controls designed by management to determine the 
categories and proportion of direct costs of installation, overheads 
and other expenses directly attributable to bringing the meter 
assets into use by the group’s in-house engineering teams and 
evaluated the design effectiveness of these controls.
We evaluated the judgement applied by management to assess 
the appropriate categories and proportion of direct costs of 
installation, overheads and other expenses directly attributable 
to installation of meter assets. This included:
•	Assessment of the capitalisation methodology applied 
and testing of the mathematical integrity of the model;
•	Testing of the time recording data utilised to determine 
the proportion of engineers’ time spent installing;
•	Agreement of the costs to the audited trial balance; and
•	Testing of categorisation of costs capitalised to ensure they 
related to directly attributable costs of fitting the meter. 
Costs that did not relate to the meter fitting were excluded. 
The excluded costs included inefficiencies in meter fitting, 
time spent on training and time spent on transactional work.
•	Benchmarking the average installation cost capitalised 
to contracted third party installation costs to assess 
the reasonableness of the amount capitalised.
•	Reviewing the subsequent depreciation applied to the capitalised 
costs and their presentation within the financial statements.
•	We performed full and specific scope audit procedures over 
this risk area, which covered 100% of the risk amount.
Based on the results of our 
audit procedures, we consider 
the amounts capitalised for 
meters installed by in-house 
engineers to be appropriate.
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 £1.1million (2021: £0.8 million), which is 5% (2021: 5%) of PBT before exceptional 
items. We believe that pre-tax profits before exceptional items provides us with an appropriate materiality threshold for the 
users of the financial statements as the exceptional costs are considered non-recurring costs in the normal course of business. 
We determined materiality for the Parent Company to be £8.6million (2021: £9.3 million), which is 2% (2021: 2%) of equity. 
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% (2021: 75%) of our planning materiality, namely £0.6m (2021: £0.6m). 
122 SMS Annual report and accounts 2022

We have set performance materiality at this percentage due to our expectation of the likelihood of misstatements taking 
into account the internal control environment, accounting systems and level of estimation in the financial statements. 
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 
£0.1 million to £0.4 million (2021: £0.1 million to £0.4 million). 
Reporting threshold
An amount below which identified misstatements are considered as being clearly trivial.
We agreed with the Audit Committee that we would report to them all uncorrected audit differences in excess of £0.06m 
(2021: £0.04m), 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 1 to 118, other than the financial statements 
and our auditor’s report thereon. The directors are responsible for the other information within the annual report. 
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.
Opinions on other matters prescribed by 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 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 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
Responsibilities of directors
As explained more fully in the directors’ responsibilities statement set out on page 116, 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.

to the Members of Smart Metering Systems plc continued
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 parent 
company and determined that the most significant are those that relate to the reporting framework (IFRS, FRS 102, 
Companies Act 2006, AIM Rules for Company; QCA Code) and the relevant tax compliance regulations in the UK and 
Ireland. In addition, we concluded that there are certain significant laws and regulations that may have an effect on the 
determination of the amounts and disclosures in the financial statements and those laws and regulations relating to 
health and safety, employee matters, environmental and bribery and corruption practices; 
•	 We understood how SMS is complying with those frameworks by making enquiries of directors, internal audit, those 
responsible for legal and compliance procedures and the Company Secretary. We corroborated our enquires through 
our review of the board minutes and papers provided to the Audit Committee, as well as consideration of the results of 
our audit procedures across the group to either corroborate or provide contrary evidence which was then followed up; 
•	 We assessed the susceptibility of the group’s financial statements to material misstatement, including how fraud might 
occur, by meeting with management within various parts of the business 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 higher, we performed audit 
procedures to address the fraud risk. These procedures included testing manual journals and were designed to provide 
reasonable assurance that the financial statements were free from fraud or error;
•	 Based on this understanding we designed our audit procedures to identify non-compliance with such laws and regulations. 
Our procedures involved enquiries of group management and those charged with governance, those responsible for legal 
and compliance procedures and internal audit; journal entry testing with a focus on manual consolidation journals and 
journals indicating large or unusual transactions based on our understanding of the business and a review of Board and 
Audit Committee minutes to identify any non-compliance with laws and regulations.
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.
Use of our report 
This report is made solely to the company’s members, as a body, in accordance with Chapter 3 of Part 16 of the Companies 
Act 2006. Our audit work has been undertaken so that we might state to the company’s members those matters we are 
required to state to them in an auditor’s report and for no other purpose. To the fullest extent permitted by law, we do not 
accept or assume responsibility to anyone other than the company and the company’s members as a body, for our audit 
work, for this report, or for the opinions we have formed.

The significant accounting policies adopted in the preparation of these consolidated financial statements are set out below. 
These policies have been consistently applied to all the years presented, unless otherwise stated. The consolidated financial 
statements of the Group for the year ended 31 December 2022 were approved and authorised for issue in accordance with a 
resolution of the Directors on 14 March 2023. Smart Metering Systems plc (SMS) is a public limited company limited by shares 
and incorporated in Scotland, with its registered office at 2nd Floor, 48 St. Vincent Street, Glasgow G2 5TS. The Company’s 
ordinary shares are traded on AIM. 
Basis of preparation
The consolidated financial statements have been prepared in accordance with UK-adopted international accounting standards.
The consolidated financial statements have been prepared on a historical cost basis, modified by the revaluation of certain 
financial assets and financial liabilities that have been measured at fair value.
The consolidated financial statements are presented in British Pounds Sterling (£), which is Smart Metering Systems plc’s 
functional and presentation currency, and all values are rounded to the nearest thousand (£’000) except where otherwise indicated.
Following an IFRIC agenda decision in March 2022 cash and cash equivalents now include restricted cash. Amounts shown 
for 2021 have been restated on a comparable basis.
In preparing the consolidated financial statements management has considered the impact of climate change, particularly 
in the context of the disclosures included in the Strategic report and the Group’s net-zero carbon target. Our net-zero plans 
are to electrify our vehicle fleet and carry out sustainability upgrades to our building estate. The fleet will be replaced at the 
end of the useful life. These considerations did not have a material impact on the financial reporting judgements and 
estimates, consistent with the assessment that climate change is not expected to have a significant impact on the Group’s 
going concern assessment to December 2024. Qualitative explorations of potential areas of concern, including an evaluation 
of climate exposure on our physical assets such as offices, warehouses and vehicles, has been carried out and we have 
identified areas of potential climate-related risk, such as extreme weather events which could affect our physical locations 
and road-based employees. Overall, the risk of climate-related change on the Group is considered low.
Going concern
Management prepares budgets and forecasts on a five-year forward-looking basis. These forecasts cover operational 
cash flows and investment capital expenditure and are prepared based on management’s estimation of installation run 
rates through the UK smart meter rollout. The Directors have performed their assessment of the entity’s ability to continue 
as a going concern, from the date of issue of these financial statements to 31 December 2024. 
Management has modelled several different meter installation and grid-scale battery storage scenarios, including a 
downside scenario which assumed a reduced rollout of new meter installations over the five-year period and delayed the 
energisation of grid-scale battery storage sites. The scenario proved that the business would still have sufficient cash flow 
to continue to operate, banking covenants would remain satisfied with adequate headroom, and adequate cash would be 
available to cover liabilities and operating costs. This modelling provides confidence to management that, even in adverse 
circumstances, the business will still have sufficient resources to continue to operate. 
In September 2021, the Group completed the refinancing of its revolving credit facility in order to support ongoing 
investment in its established carbon reduction (‘CaRe’) assets. The total available funding under the new loan facility 
is £420m and the maturity date is December 2025. In October 2021, the Group completed a successful equity placing, 
raising proceeds of c.£175m. These proceeds were used to make a voluntary prepayment under the Group’s refinanced 
loan facility of the full outstanding principal of c.£53m. At 31 December 2022, the Group had a drawn-down amount of 
£65m (31 December 2021: £nil). 
The Group was compliant with all its debt covenants at 31 December 2022. The financial covenants attached to the facility 
are that EBITDA should be no less than 4.00x interest and net debt should be no more than 4.75x EBITDA. At 31 December 2022 
these stood at 18.84x and 0.45x respectively, demonstrating significant headroom. The Group does not expect to breach 
these covenants in the period from the date of release of these financial statements to 31 December 2024, being the period 
for the going concern assessment. 
The Group balance sheet shows consolidated net assets of £533.5m (31 December 2021: £553.8m), of which £429.7m 
(31 December 2021: £366.7m) relates to revenue-generating meter and data assets. The liquidity of the Group thus 
remains strong and continues to provide the financial flexibility required to support the Group’s long-term growth prospects. 
With significant coverage provided by existing long-term, inflation-linked and recurring cash flows, the Group remains 
committed to its enhanced dividend policy. It proposes a 30.25p per share annualised dividend in respect of FY 2022. 
The first of four cash instalments, a total of £10.1m, was paid in October 2022.

Going concern continued
Based on the current cash flow projections and facilities in place and having given consideration to various outcomes 
of future performance and forecast capital expenditure, including extreme downside scenarios, the Directors consider 
it appropriate to continue to prepare the financial statements on a going concern basis and are of the view that there 
are no material uncertainties regarding the Group’s going concern status. 
Basis of consolidation
The consolidated accounts of the Group include the assets, liabilities and results of the Company and subsidiary 
undertakings in which Smart Metering Systems plc has a controlling interest. Control is achieved when the Group is exposed, 
or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its 
power over the investee. Specifically, the Group controls an investee if, and only if, the Group has all the following: power over 
the investee (i.e. existing rights that give it the current ability to direct the relevant activities of the investee); exposure, or 
rights, to variable returns from its involvement with the investee; and the ability to use its power over the investee to affect 
its returns. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are 
deconsolidated from the date that control ceases.
The acquisition method of accounting is used to account for business combinations by the Group (refer to policy on page 139). 
When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line 
with the Group’s accounting policies. 
All intra-group assets and liabilities, equity, income, expenses and cash flows relating to transactions between members 
of the Group are eliminated in full on consolidation.
Foreign currency translation
Group companies
The results and financial position of foreign operations (none of which has the currency of a hyperinflationary economy) that 
have a functional currency different from the presentation currency are translated into the presentation currency as follows:
•	 assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet;
•	 non-monetary assets at the date of acquisition are translated at the historical rate and are not subsequently revalued;
•	 income and expenses for each statement of profit or loss and statement of comprehensive income are translated at 
average exchange rates (unless this is not a reasonable approximation of the cumulative effect of the rates prevailing 
on the transaction dates, in which case income and expenses are translated at the dates of the transactions); and 
•	 all resulting exchange differences are recognised in Other comprehensive income and accumulated in a separate reserve 
within equity.
Goodwill and fair value adjustments arising on the acquisition of a foreign operation are treated as assets and liabilities 
of the foreign operation and translated at the closing rate.
Transactions and balances
Foreign currency transactions are translated into the functional currency using the exchange rates at the dates of the 
transactions. Foreign exchange gains and losses resulting from the settlement of such transactions, and from the translation 
of monetary assets and liabilities denominated in foreign currencies at year-end exchange rates, are generally recognised in 
profit or loss. They are deferred in equity if they relate to qualifying cash flow hedges and qualifying net investment hedges 
or are attributable to part of the net investment in a foreign operation.
Foreign exchange gains and losses that relate to borrowings are presented in the statement of profit or loss, within Finance 
costs. All other foreign exchange gains and losses are presented in the statement of profit or loss on a net basis within 
Administrative expenses. 
Use of estimates and judgements
The Directors are required to make judgements, estimates and assumptions about the carrying amount of assets and 
liabilities that are not readily apparent from other sources. These estimates and associated assumptions are based on 
historical experience and other factors considered to be relevant. Actual results may differ from these estimates. The 
estimates and underlying assumptions 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 period, or in the period of the revision and future 
periods if the revision affects both current and future periods.

Critical accounting judgements
The following are the critical judgements that the Directors have made in the process of applying the Group’s accounting 
policies and that have the most significant effect on the amounts recognised in the financial statements:
•	 capitalisation of internal installation costs:
	−a significant level of in-house installation of meter assets is carried out by the Group, certain costs of which are 
capitalised (2022: £51.8m, 2021: £38.2m) and depreciated as part of property, plant and equipment depreciation. 
Judgement is required by management to ascertain the appropriate categories and proportion of overheads and other 
expenses that are directly attributable to installation of meter assets. Typically, capitalised costs will include staff costs, 
and a systematic allocation of any production overheads deemed to be directly attributable to the process of installing 
a meter owned by the Group. Other general and administrative overheads, such as sales, marketing and training costs, 
are expensed directly to profit and loss; 
•	 presentation of losses on disposal of certain meter assets as exceptional items:
	−as a result of the inherent volatility associated with the UK smart meter rollout, and removal of traditional meter assets 
as part of this, management has taken the decision to show losses arising on disposal of these meters – being the net 
book value less the associated termination income received representing proceeds on disposal – as exceptional 
administrative expenses. By disclosing these amounts separately, the traditional meter asset portfolio can be better 
tracked to assist users of the financial statements to better understand the premature retirement of these revenue-
generating assets that is outside the Group’s control. On disposal, the receipt of termination income which is recognised 
as a component of the net gain or loss on the disposal of these meter assets, will vary depending on the energy supplier 
and is therefore not within our control. As the receipt of proceeds from disposal is inherently volatile, a loss on disposal 
can still arise in certain circumstances; and 
	−the Group has continued to see a small proportion of SMETS1 meters removed from the wall. As these removals are 
attributable to the temporary industry transition period, management has made the judgement to recognise losses arising 
on the disposal of these meters as exceptional until resolution by the Enrolment and Adoption programme is complete; and 
•	 identification of indicators of impairment of the meter asset portfolio in accordance with IAS 36 and assumptions applied 
in determining the carrying value of the portfolio of meter assets:
	−due to the uncertainties associated with the timing of the UK domestic smart meter rollout, the expected useful life and 
carrying value of traditional meters requires significant judgement, as does the level of recoverability of termination income. 
These assumptions are used in deriving the depreciation rates applied and the impairment calculation performed on 
carrying value. For the traditional meters, as the UK smart meter rollout progresses, our portfolio of traditional meter 
assets is diminishing. It is therefore crucial that the recoverability of the carrying value of these meter assets, recognised 
in Property, plant and equipment, be assessed. The two main drivers for assessing this recoverability are:
1.	 the timing of the removals of these meters – this decision lies with the end consumer and removals are largely undertaken 
by third parties, which means we have little control over the timing and quantity of these removals; and
2.	 the estimated future cash flows from termination income – these are derived using historical data and analysis around the 
risk of churn between contracted and non-contracted customers. The assessment includes consideration of the extent to 
which termination income and future rental income are received as traditional meters continue to be removed from the wall. 
In 2022, this assessment has identified that the carrying value of the traditional meter assets portfolio is recoverable and, 
therefore, no impairment charge has been recognised (2021: £nil).
	−potential indicators of impairment have also been assessed in relation to our smart and I&C meters, including 
consideration of the temporary industry transitional issues experienced with some SMETS1 assets as detailed above. 
Management has concluded that there is no significant risk of impairment with regards to the Group’s smart and I&C 
meters at 31 December 2022, consistent with the prior year.
Key sources of estimation uncertainty 
The Group has no key sources of estimation uncertainty at the reporting date that may have a significant risk of causing 
material adjustment to the carrying amounts of assets and liabilities within the next financial year.

Revenue recognition
i. Metering 
Meter rental
The Group acts as a gas and electricity Meter Asset Provider (MAP), providing and installing meters to energy suppliers on 
behalf of the end consumer. 
As a result of the Group’s assessment of contracts on implementation of IFRS 16, and any potential interaction with IFRS 15, 
it was determined that the arrangements the Group has in place to act as MAP do not constitute a lease of the meter asset 
to the energy supplier. Therefore, the related income for the service of providing a fitted meter is recognised in accordance 
with IFRS 15. 
The provision of meter assets to energy suppliers (‘MAP services’), together with the initial installation, is considered a 
distinct and single performance obligation on the basis that, as MAP, the Group has an obligation to its customers to provide 
a fitted meter. This is a separately identifiable service to which a stand-alone selling price is typically allocated. Over the 
course of the contract term, which runs in perpetuity, the Group delivers a series of monthly services for which benefits are 
simultaneously received and consumed by the customer. 
Charges for MAP services are calculated daily based on the number of installed meters and invoiced to customers monthly 
once validation checks have been completed. As revenue from MAP charges is attributed to services provided daily, revenue 
is always based on the actual level of service provided and, therefore, any uncertainty at the end of each reporting period is 
limited to the extent that validation checks are still being completed. Revenue is thus recognised over time based on our 
right to invoice and includes contract Retail Price Index (RPI) uplifts. 
As a result of industry regulations, and subject to specific contract terms with a customer, the Group may be required 
to make payments to customers for shortfalls in the level of service provided. These charges are directly related to the 
service being provided to the customer and thus are recognised as a reduction to revenue in the month in which the service 
failure occurred. Where service levels are set based on annual targets, charges are estimated monthly and subsequently 
finalised at the end of the year. Uncertainty, as it pertains to these payments to customers, is thus typically resolved by the 
end of the reporting period. 
If a MAP contract is cancelled, termination fees may be levied on the energy supplier. There has been no change in the 
accounting for these termination fees and they continue to be classified within Other operating income unless they have 
arisen on the loss of the meter assets, in which case they are reported within Administrative expenses as a component of net 
gain or loss on disposal.
If the services rendered by the Group exceed the payment received, then accrued income is recognised. This is subsequently 
reclassified to receivables at the point at which the Group has an unconditional right to payment.
Asset management services
The Group provides meter asset management and operations services to energy suppliers. These services are considered 
a distinct performance obligation from the meter rental on the basis that these are separately identifiable services to which 
a stand-alone selling price is allocated, and they are not necessary to bring the meter asset into use.
Over the course of the contract term, which can either be fixed or in perpetuity, the Group delivers a series of monthly 
services for which the benefits are simultaneously received and consumed by a customer. Therefore, these are accounted 
for as a single performance obligation. 
Service charges are calculated based on the number of meters appointed and are accrued monthly. As revenue from service 
charges is attributed to services provided periodically, revenue is always based on the actual level of service provided and, 
therefore, there is no uncertainty at the end of each reporting period. For charges invoiced to customers monthly revenue is 
thus recognised over time based on our right to invoice and includes contract RPI uplifts. For charges invoiced to customers 
annually in advance, including contract RPI uplifts, a contract liability is recognised and subsequently released to the income 
statement over the year on a straight-line basis. The Group uses the practical expedient under IFRS 15 from adjusting 
revenue for any significant financial components of one year or less.
The Group’s meter asset management contracts also include the provision of transactional meter works. These are 
considered further in section (iv) below. 
If the services rendered by the Group exceed the payment received, then a contract asset is recognised. This is subsequently 
reclassified to receivables at the point at which the Group has an unconditional right to payment.
Accounting Policies continued
132 SMS Annual report and accounts 2022

Third-party management services
The Group provides management services to a third party to whom it sold a minority of its meter asset portfolio in 
April 2020. These services include accounting and treasury, portfolio asset management and other administrative tasks. 
The various activities that make up these management services are provided to the third party on an integrated basis. 
Over the course of the contract term, which runs for as long as there are meters within the scope of the services, the Group 
delivers a series of monthly services for which the benefits are simultaneously received and consumed by the customer. 
Therefore, these are accounted for as a single performance obligation. 
Service charges are currently based on a fixed annual fee, subject to contract RPI uplifts, and are invoiced to the customer 
monthly. Revenue is thus recognised over time based on our right to invoice.
If the services rendered by the Group exceed the payment received, then a contract asset is recognised. This is subsequently 
reclassified to receivables at the point at which the Group has an unconditional right to payment.
ii. Data services 
The Group provides data collection and aggregation services to Industrial & Commercial (I&C) electricity customers and, 
through use of the ADM™ unit, to I&C gas customers. Over the course of the contract term, which can either be fixed or in 
perpetuity, the Group delivers a series of monthly services for which the benefits are simultaneously received and consumed 
by a customer. Therefore, these are accounted for as a single performance obligation. 
Service charges are calculated based on the number of meters/ADM™ units appointed and are accrued monthly. As revenue 
from service charges is attributed to services provided periodically, revenue is always based on the actual level of service 
provided and, therefore, there is no uncertainty at the end of each reporting period. Service charges, including contract RPI 
uplifts, are billed to clients annually in advance and therefore a contract liability is recognised and subsequently released to 
the income statement over the year on a straight-line basis. The Group uses the practical expedient under IFRS 15 from 
adjusting revenue for any significant financial components of one year or less.
The ADM™ device is a proprietary product for the Group and there are no other market providers of this device. A customer 
cannot therefore benefit from the data services without installation, and the installation is not separately identifiable as it is 
integral to the subsequent data services. This is therefore accounted for along with the data services as a single 
performance obligation and any corresponding charges are recognised over the term of the contract. 
iii. Utility connections services (gas and electricity)
Gas and electricity connections services are provided under fixed-price contracts with I&C customers and can be delivered to 
a single site or multiple sites. Whilst each service consists of multiple activities, the Group’s promise in the contract is to deliver an 
integrated end-to-end service to which the underlying activities are inputs. Where services are delivered to multiple sites, and 
these are substantially the same, a series of services is being provided. In all cases, therefore, these contracts give rise to a single 
performance obligation to which the fixed price is allocated. Subsequent variations to this price, due to changes in the inputs 
required, are accounted for as contract modifications and recognised on a cumulative catch-up basis. 
Services are transferred over time on the basis that these are customised services with no alternative use and the Group 
has an enforceable right to payment for work completed to date.
Revenue is recognised on the stage of completion with reference to the actual services provided as a proportion of the total 
service expected to be provided under the contract, as the services can enhance a work-in-progress asset for the customer 
and have no alternative use. This is determined on a contract-by-contract basis using a milestone approach with reference 
to the milestones set out in the contract or otherwise agreed. Where relevant, consideration is also given to material services 
provided between milestones. Estimates of revenues, costs or extent of progress towards completion are revised if 
circumstances change and any resulting increases or decreases in estimated revenues or costs are reflected in profit or loss 
in the period in which the circumstances that give rise to the revision become known to management. 
The customer pays the fixed amount based on a payment schedule. In certain circumstances the customer pays in advance 
and therefore a contract liability is recognised and subsequently released to the income statement based on the measure 
of progress detailed above. As the contract is cancellable at the customer’s discretion, subject to settlement for services 
provided to the date of cancellation, a contract liability is not recognised until the cash has been received.
If the services rendered by the Group exceed the payment received, then a contract asset is recognised. This is subsequently 
reclassified to receivables at the point at which the Group has an unconditional right to payment. 
The Group utilises the practical expedient available under IFRS 15 for costs to obtain a contract. Commissions paid as part 
of obtaining a contract are expensed as incurred on the basis that the contract term is typically less than twelve months.

Revenue recognition continued
iv. Transactional meter works
Transactional works, which include emergency, adversarial and other maintenance services, and are typically short term in 
nature, are accounted for as a separate performance obligation to asset management services (see section (i) above) on 
the basis that these works are separately identifiable and can be performed by another party. A customer, being the energy 
supplier, is legally obligated to appoint a meter asset manager and can therefore benefit from this service in isolation, 
without the subsequent transactional works which are initiated on an ad-hoc basis upon demand by the customer. 
In 2020, the Group also started to provide transactional meter works to the third party to whom the Group sold a minority 
of its meter asset portfolio in April 2020.
The transaction price allocated to transactional works is based on stand-alone selling prices (per unit, where relevant) 
and revenue is recognised at a point in time when the transaction has been completed and accepted by the customer. 
This is the point at which the customer is charged for the service and a receivable is recognised by the Group as we have 
an unconditional right to payment. The customer will settle the transaction price for these services as part of the regular 
monthly billing cycle for metering and asset management services.
The customer pays the fixed amount based on the transactional services provided and this is charged once the service 
has been completed and accepted by the customer.
For segmental purposes, this transactional, non-recurring revenue is recognised within asset installation.
v. Grid-scale batteries
Grid-scale battery assets generate revenue by providing several services.

SMS enters into longer term contracts with the National Grid. During the contract period, which may last from one to 
15 years, SMS’s only obligation is to make itself available to provide the capacity agreed in the contract when notification 
is received from National Grid. Pricing is fixed at an auction. 
There is a single performance obligation to be available to provide capacity to the National Grid. Revenue is recognised over time.
Wholesale market
SMS trades power with a counterparty on an exchange on the EPEX GB Day Ahead and Intraday markets, with the intention 
of buying power at a low off-peak price and selling at a high peak price. All trades take place at spot price and there are no 
forward or future contracts. All trades are settled daily.
There is a single performance obligation for SMS to buy or sell power on the exchange. Revenue is recognised for each 
transaction at a point in time.
Balancing mechanism
SMS enters into short-term contracts with Elexon BSC to help balance the demands of the National Grid by increasing or 
decreasing generation (or consumption). Contracts range for a length of one to 60 minutes and prices are fixed when a bid 
is submitted. Elexon accepts only the cheapest bids needed to balance the grid. 
There is a single performance obligation for SMS to increase or decrease its battery asset output. Revenue is recognised 
over time. However, due to the short-term nature of the contracts, there would be no material difference between 
recognition over time or at a point in time.
Ancillary services market
SMS enters into contracts with the National Grid to help maintain frequency on the grid. During the contract period SMS 
is required to use the grid-scale battery asset following the Grid’s instructions. The price is fixed at auction.
Revenue is recognised over time. However, due to the short-term nature of the contracts, there would be no material 
difference between recognition over time or at a point in time.
Embedded benefits
SMS enters into contracts with the National Grid and the Distribution Network Operator under which SMS is paid based 
on the amount of electricity exported during Triad or peak periods.
There is a single performance obligation to export capacity during Triad or peak periods. Revenue is recognised over time. 
However, due to the short-term nature of the contracts, there would be no material difference between recognition over time 
or at a point in time.

Imbalance
Elexon BSC is obliged to purchase or sell electricity generated or sold in any half-hour period which is not otherwise 
contracted for. SMS buys or sells power to meet its requirements for the other revenue streams. The purchase and selling 
prices are at a spot price set by a formula.
There is a single performance obligation for SMS to export or import power. Revenue is recognised for each transaction 
at a point in time. 
vi. Energy management services
Energy management services provided mainly to I&C customers include utility bureau and bill validation services, risk 
management and procurement services and energy reduction and environmental management services.
Certain services, such as utility bureau and bill validation, are delivered through a series of monthly services over the course 
of the contract term, for which the benefits are simultaneously received and consumed by a customer. These are accounted 
for as a single performance obligation. The transaction price allocated includes a fixed monthly service charge together with 
a variable component for specific activities that may not be carried out every month. As revenue from charges is attributed 
to services provided monthly, revenue is always based on the actual level of service provided and, therefore, there is no 
uncertainty at the end of each reporting period. Revenue is thus recognised over time based on our right to invoice.
Contracts for specialist consultancy services may include multiple projects. Where these projects are separately identifiable 
within the contract and are not interrelated, they are accounted for as separate performance obligations. The transaction 
price is allocated based on the stand-alone charges for each project. 
Other energy reduction and environmental management services are typically longer-term, multi-site contracts and, therefore, 
the revenue recognition is consistent with that detailed above for utility connections – see details in section (iii) above.
vii. Assets and liabilities arising from contracts with customers
Costs to fulfil a contract
In certain circumstances, the Group may incur costs to fulfil its obligations under a contract once it is obtained, but before 
transferring goods or services to the customer. These costs are assessed on a contract-by-contract basis and, where they 
are considered to meet the definition of fulfilment costs under IFRS 15, they are recognised as an asset and amortised on 
a systematic basis consistent with the pattern of transfer of the services to which the asset relates. 
Contract assets and liabilities
We receive payments from customers based on a billing schedule, as established in our contracts. 
The timing of revenue recognition, billing and cash collections results in:
•	 billed and unbilled accounts receivable, which are recognised when our right to consideration becomes unconditional, 
and classified as trade receivables and accrued income respectively;
•	 unbilled amounts, where we have a conditional right to consideration based on future performance, recognised as contract 
assets. These amounts will be billed in accordance with the agreed-upon contractual terms; and
•	 payments received in advance of performance under a contract, recognised as contract liabilities. Contract liabilities are 
recognised as revenue as (or when) we perform under a contract.
For project-based services, work in progress is billed in accordance with the agreed-upon contractual terms with the 
customer. We typically receive interim payments as work progresses, which can give rise to a billed or unbilled accounts 
receivable, where our right to payment is unconditional, or a contract asset, where revenue has been recognised based 
on progress completed but our right to payment is still conditional on future performance. For some contracts, we may 
be entitled to receive advance payments. We recognise a contract liability for these advance payments in excess of 
revenue recognised.
Cancellation terms can vary but typically include provisions that allow the customer to terminate the contract at their 
discretion subject to a penalty or settlement of amounts for work completed prior to termination. Contracts allow both 
parties to cancel without penalty in the case of a material breach of contract.

Exceptional items and separately disclosed items
The Group presents as exceptional items on the face of the consolidated statement of comprehensive income those items 
of income and expense which, because of the material nature or expected infrequency of the events giving rise to them, 
merit separate presentation to allow shareholders to better understand the elements of financial performance in that year 
facilitating comparison with prior periods and to better assess trends in financial performance. 
Termination fee income is reported as part of Other operating income in the consolidated statement of comprehensive 
income given its materiality and nature. Any termination fee income arising on the loss of meter assets is reported within 
Administrative expenses as a component of net gain or loss on disposal. Termination fee income does not arise from the 
principal activities of the Group. Any such gain or loss on disposal relating to traditional meter assets and SMETS1 meter 
assets is disclosed as an exceptional item.
Government grants
Grants from governments are recognised at their fair value where there is reasonable assurance that the grant will be 
received and the Group will comply with all attached conditions, usually on submission of a valid claim for payment. 
Government grants relating to costs are deferred and recognised in profit or loss over the period necessary to match them 
with the costs that they are intended to compensate. Government grants relating to capital expenditure are included in 
liabilities as deferred income and they are credited to profit or loss on a straight-line basis over the expected lives of the 
related assets. Amounts credited to profit or loss are recognised as part of Other operating income in the consolidated 
statement of comprehensive income. 
The R&D expenditure credit (RDEC) scheme is a UK Government tax incentive which allows qualifying companies to claim 
R&D expenditure credits (RDECs) equal to 12% of their qualifying research and development expenditure. The credit is 
taxable at the corporation tax rate and is included in the company’s taxable trading profits. RDECs are accounted for by 
the Group in accordance with IAS 20 Government Grants and recognised within Other operating income in the consolidated 
statement of comprehensive income. Outstanding amounts receivable are recognised in the consolidated balance sheet 
within Trade and other receivables.	
Financial assets
The Group’s financial assets include cash and cash equivalents and trade and other receivables. Investments consist 
of an immaterial debt investment held at amortised cost.
Classification
The Group classifies its financial assets in the following measurement categories: 
•	 those to be measured subsequently at fair value, either through other comprehensive income (FVOCI) or through profit 
or loss (FVPL); and 
•	 those to be measured at amortised cost. 
The classification depends on the Group’s business model for managing the financial assets and the contractual terms 
of the cash flows. 
For investments in equity instruments that are not held for trading, this will depend on whether the Group has made an 
irrevocable election at the time of initial recognition to account for the equity investment at FVOCI. The Group reclassifies 
debt investments when and only when its business model for managing those assets changes. 
Recognition and derecognition
Financial assets are initially recognised on trade date. Financial assets are derecognised when the rights to receive cash 
flows from the financial assets have expired or have been transferred and the Group has transferred substantially all the 
risks and rewards of ownership. 
Measurement
At initial recognition, the Group measures a financial asset at its fair value plus, in the case of a financial asset not at FVPL, 
transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets 
carried at FVPL are expensed in profit or loss.
Trade and other receivables
Trade and other receivables are recognised initially at the IFRS 15 transaction price and subsequently measured at amortised 
cost. They are generally due for settlement within 30 days and are therefore all classified as current. Due to their short-term 
nature, carrying value is considered to approximate fair value.
Accounting Policies continued
136 SMS Annual report and accounts 2022

Cash and cash equivalents
Refer to accounting policy on Cash and cash equivalents.
Impairment 
The Group assesses, on a forward-looking basis, the expected credit losses associated with its debt instruments carried at 
amortised cost and FVOCI. The impairment methodology applied depends on whether there has been a significant increase 
in credit risk. For trade receivables and accrued income, which include contract assets and billed and unbilled receivables 
arising from contracts with customers, the Group applies the simplified approach permitted by IFRS 9, which requires 
expected lifetime losses to be recognised from initial recognition of the receivables.
Trade receivables and accrued income are written off, and derecognised, where there is no reasonable expectation of recovery. 
Indicators that there is no reasonable expectation of recovery include, amongst others, the customer ceasing trading and 
entering administration with no expected recovery from the Supplier of Last Resort process, or a failure by the customer to 
make contractual payments for a period of greater than or equal to 365 days past due. Indicators are assessed on an individual 
customer basis. Impairment losses, including the loss allowance, on trade receivables and accrued income are presented within 
Administrative expenses. Subsequent recoveries of amounts previously written off are credited against the same line item. 
Further information about the impairment of trade receivables and accrued income, and the Group’s exposure to credit risks, 
can be found in note 23. 
Financial liabilities
The Group’s financial liabilities include trade and other payables, bank loans and overdrafts, and leases. 
Classification
Financial liabilities are classified as financial liabilities at fair value through profit or loss or loans and borrowings, 
as appropriate. The Group determines the classification of its financial liabilities at initial recognition. 
Recognition
All financial liabilities are recognised initially at fair value and, in the case of bank loans, net of directly attributable 
transaction costs. 
Measurement
Trade and other payables and bank overdrafts
Trade and other payables, and overdrafts, are subsequently measured at amortised cost using the effective interest rate 
method. Trade and other payables are presented as current liabilities unless payment is not due within twelve months after 
the reporting period. Due to their short-term nature, carrying value is considered to approximate fair value.
Bank loans
Bank loans are subsequently measured at amortised cost. Interest expense on bank loans is recognised in the consolidated 
income statement using the effective interest rate method.
Transaction costs on revolving credit facilities are recognised as transaction costs of the loan to the extent that it is probable 
that some or all the facility will be drawn down. In this case, the fee is deferred within Other assets until the drawdown occurs. 
Upon drawdown of the first loan, these costs are reclassified from Other assets to Bank loans and subsequently amortised 
over the term of the facility. 
Borrowings are removed from the balance sheet when the obligation specified in the contract is discharged or cancelled or 
has expired. The difference between the carrying amount of a financial liability that has been extinguished or transferred to 
another party and the consideration paid, including any non-cash assets transferred, or liabilities assumed, is recognised in 
profit or loss as Other income or Finance costs. 
If a facility is modified, then it is assessed whether the modification is significant enough to constitute an extinguishment either 
qualitatively or quantitatively (defined as a change in the present value of cash flows, including any transaction costs paid, 
exceeding 10%). If a modification is considered an extinguishment of the initial loan, the new modified loan is recorded at fair 
value and a gain/loss is recognised immediately in the consolidated income statement for the difference between the carrying 
amount of the old loan and the new loan. Any costs incurred are recognised in profit or loss. Where a modification is not 
significant enough to be an extinguishment, the cash flows under the modified loan are rediscounted at the original effective 
interest rate and an immediate gain or loss is recognised accordingly in the consolidated income statement on the date of 
modification. Any costs incurred are recognised over the remaining period of the modified debt, within the effective interest rate.
Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability 
for at least twelve months after the reporting period.

Offsetting of financial instruments
Financial assets and financial liabilities are offset, and the net amount reported in the consolidated statement of financial 
position, if, and only if, there is a currently enforceable legal right to offset the recognised amounts and there is an intention 
to settle on a net basis, or to realise the assets and settle the liabilities simultaneously.
Leases
Group as lessor
The arrangements the Group has in place to act as Meter Asset Provider do not constitute a lease of the meter asset to the 
energy supplier. SMS controls the meter as the Group retains legal title and obtains substantially all the economic benefit. 
The assets are recognised as property, plant and equipment when in use under contract with an energy supplier and the 
related income for the service of providing a fitted meter is recognised in accordance with IFRS 15. Further information about 
the Group’s accounting policy for revenue recognition is given above, and for property, plant and equipment in note 11. 
Group as lessee
The Group leases land, offices, warehouses and motor vehicles. For offices, warehouses and motor vehicles rental contracts 
are typically made for fixed periods of three to ten years. For land, rental contracts are typically made for fixed periods of 
20 to 40 years. Contracts may have extension or early termination options. Lease terms are negotiated on an individual 
basis and contain a wide range of different terms and conditions. The lease agreements do not impose any covenants, 
but leased assets may not be used as security for borrowing purposes.
Leases are recognised as a right-of-use asset and a corresponding liability at the date at which the leased asset is available 
for use by the Group. 
In determining the lease term, management considers all facts and circumstances that create an economic incentive to 
exercise an extension option, or not exercise a termination option. Extension options (or periods after termination options) 
are only included in the lease term if the lease is reasonably certain to be extended (or not terminated). The lease term is 
reassessed if an option is actually exercised (or not exercised) or the Group becomes obliged to exercise (or not exercise) it. 
The assessment of reasonable certainty is only revised if a significant event or a significant change in circumstances occurs, 
which affects this assessment, and that is within the control of the lessee. 
Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the net 
present value of the following lease payments:
•	 fixed payments (including in-substance fixed payments), less any lease incentives receivable;
•	 variable lease payments that are based on an index or a rate, initially measured using the index or rate as at the 
commencement date;
•	 amounts expected to be payable by the lessee under residual value guarantees;
•	 the exercise price of a purchase option if the lessee is reasonably certain to exercise that option; and
•	 payments of penalties for terminating the lease, if the lease term reflects the lessee exercising that option.
Lease payments to be made under reasonably certain extension options are also included in the measurement of the liability.
The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be determined, the lessee’s 
incremental borrowing rate is used, being the rate that the lessee would have to pay to borrow the funds necessary to obtain 
an asset of similar value in a similar economic environment with similar terms and conditions. The weighted average lessee’s 
incremental borrowing rate applied to the lease liabilities at 31 December 2022 was 5% (31 December 2021: 4.7%). 
The Group is exposed to potential future increases in variable lease payments based on an index or rate, which are not 
included in the lease liability until they take effect. When adjustments to lease payments based on an index or rate take 
effect, the lease liability is reassessed and adjusted against the right-of-use asset.
Lease payments are allocated between principal and finance cost. The finance cost is charged to profit or loss over the 
lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period.
Right-of-use assets are measured at cost comprising the following:
•	 the amount of the initial measurement of lease liability;
•	 any lease payments made at or before the commencement date less any lease incentives received;
•	 any initial direct costs; and
•	 restoration costs. 
Accounting Policies continued
138 SMS Annual report and accounts 2022

The Group is required to restore the land leased as part of its grid-scale battery storage business, and certain leased warehouses, 
to the condition required by the terms and conditions of the lease at the end of the respective lease terms. Under IFRS 16, the 
estimated liability for such restoration costs is recognised as a provision under IAS 37 at initial recognition and is not included as 
part of the lease liability. As right-of-use assets are measured subsequent to initial recognition using a cost model, any change in 
the estimate of such costs after initial recognition is added to, or deducted from, the cost of the right-of-use asset. 
Right-of-use assets are generally depreciated over the shorter of the asset’s useful life and the lease term, on a straight-line basis. 
Payments associated with short-term leases and leases of low-value assets are recognised on a straight-line basis as an 
expense in profit or loss. Short-term leases are leases with a lease term of twelve months or less. Low-value assets comprise 
IT equipment and small items of office furniture, where the value of the asset on inception is less than c.US$5,000.
Payments for services are separated from the lease components of a contract and accounted for as an administrative expense.
Provisions
Provisions are recognised when the Group has a present legal or constructive obligation as a result of a past event, it is probable 
that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate can be 
made of the amount of the obligation.
The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the end 
of the reporting period, taking into account the risks and uncertainties surrounding the obligation.
If the effect of the time value of money is material, provisions are determined by discounting the expected future cash flows at 
a discount rate that reflects the current market assessments of the time value of money. Where discounting is used, the increase 
in the provision due to the passage of time is recognised within finance costs. 
Provisions are split between amounts expected to be settled within 12 months of the balance sheet date (current) and amounts 
expected to be settled later (non-current). 
Decommissioning and restoration provisions
Provisions for decommissioning and restoration costs arise in connection with the Group’s grid-scale battery storage business, 
and with certain leased warehouses. The Group is required to restore the land leased as part of its grid-scale battery storage sites, 
and certain leased warehouses, to the condition required by the terms and conditions of the lease at the end of the respective 
lease terms (which range between three to ten years for warehouses, and 20 to 40 years for land). The amount recognised is the 
present value of the estimated future expenditure determined in accordance with current conditions, requirements, and price 
levels, discounted over the useful economic life of the asset where appropriate. The effects of changes resulting from revisions to 
the timing or amount of the original estimate of the provision are reflected on a prospective basis, generally by adjustment to the 
carrying amount of the related right-of-use asset recorded within property, plant and equipment.
An amount equivalent to the decommissioning provision is recognised as part of the corresponding right-of-use asset, which is 
subsequently depreciated at the same rate as the rest of the asset. Other than the unwinding of discount on or utilisation of the 
provision, any change in present value of the estimated expenditure is reflected as an adjustment to the provision and the 
corresponding asset. 
Provisions also include the estimated cost to decommission grid-scale battery assets at the end of their life. These costs have 
been capitalised as part of the related asset within property, plant and equipment, and are depreciated over the life of the asset. 
Changes in the provision arising from revised estimates that relate to the asset are recorded as adjustments to the carrying value 
of the asset.
Business combinations
The acquisition method of accounting is used to account for all business combinations, regardless of whether equity 
instruments or other assets are acquired. The consideration transferred for the acquisition of a subsidiary comprises the:
•	 fair values of the assets transferred;
•	 liabilities incurred to the former owners of the acquired business;
•	 equity interests issued by the Group;
•	 fair value of any asset or liability resulting from a contingent consideration arrangement; and
•	 fair value of any pre-existing equity interest in the subsidiary.
Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are, with limited 
exceptions, measured initially at their fair values at the acquisition date. The Group recognises any non-controlling interest 
in the acquired entity on an acquisition-by-acquisition basis either at fair value or at the non-controlling interest’s 
proportionate share of the acquired entity’s net identifiable assets.
SMS Annual report and accounts 2022 139

Governance
Strategic report

Business combinations continued
Acquisition-related costs are expensed as incurred.
The excess of the:
•	 consideration transferred;
•	 amount of any non-controlling interest in the acquired entity; and
•	 acquisition-date fair value of any previous equity interest in the acquired entity
over the fair value of the net identifiable assets acquired is recorded as goodwill. If those amounts are less than the fair value 
of the net identifiable assets of the business acquired, the difference is recognised directly in profit or loss as a bargain 
purchase. Where settlement of any part of cash consideration is deferred, the amounts payable in the future are discounted 
to their present value as at the date of exchange. The discount rate used is the entity’s incremental borrowing rate, being the 
rate at which a similar borrowing could be obtained from an independent financier under comparable terms and conditions.
Contingent consideration is classified either as equity or a financial liability. Amounts classified as a financial liability 
are subsequently remeasured to fair value, with changes in fair value recognised in profit or loss.
If the business combination is achieved in stages, the acquisition date carrying value of the acquirer’s previously held equity 
interest in the acquiree is remeasured to fair value at the acquisition date. Any gains or losses arising from such 
remeasurement are recognised in profit or loss.
Investments in associates
An associate is an entity in which the Group has significant influence, but not control or joint control, over the financial and 
operating policies. Interests in associates are accounted for using the equity method. They are initially recognised at cost, 
which includes transaction costs. Subsequent to initial recognition, the consolidated financial statements include the Group’s 
share of the profit or loss and other comprehensive income of the associated undertakings, until the date on which 
significant influence ceases.
Asset acquisitions
Asset acquisitions include the acquisition of a group of assets that does not constitute a business. 
The relevant IFRS is applied when accounting for the acquisition of an individual asset.
Where the acquisition involves a group of assets and liabilities, the individual assets and liabilities acquired are identified 
and recognised. The cost of the transaction is allocated to the assets acquired, and liabilities assumed, based on their 
relative fair values at the date of purchase. No goodwill arises on the transaction.
The cost of the transaction is measured at the fair value of the consideration transferred at the acquisition date. This can 
include cash payments, financial liabilities incurred, equity interests issued by the Group and the fair value of any asset or 
liability arising from a contingent or deferred consideration arrangement. Non-monetary assets might be exchanged as 
part of the consideration for the transaction. The cost of an item acquired in exchange for a non-monetary asset or assets 
is generally measured at fair value. 
Contingent consideration is classified either as equity or a financial liability. Amounts classified as a financial liability 
are subsequently remeasured to fair value, with changes in fair value recognised in profit or loss.
Transaction costs are capitalised as a component of the cost of the assets acquired.
Research and development 
Expenditure on pure and applied research activities is recognised in the consolidated statement of comprehensive income 
as an expense as incurred.
Expenditure on product and system development activities is capitalised if the product or process is technically and 
commercially feasible and the Group intends and has the technical ability and sufficient resources to complete development; 
if future economic benefits are probable; and if the Group can measure reliably the expenditure attributable to the intangible 
asset during its development. The expenditure capitalised includes the cost of materials, direct labour and an appropriate 
proportion of overheads.
Capitalised development expenditure is stated at cost less accumulated amortisation and accumulated impairment losses.
Accounting Policies continued
140 SMS Annual report and accounts 2022

Amortisation is calculated when the asset is available for use, so as to write off its cost, less its estimated residual value, over 
the useful economic life of that asset as follows:
•	 Development of ADM™ units	
10% on cost, straight line
•	 Development of internally generated information technology systems (‘IT development’)	
20% and 50% on cost, 	
	
straight line
Capitalised development expenditure on ADM™ units is disclosed within Property, plant and equipment as part of Meter 
assets and amortised over the same useful economic life as that applied to the tangible ADM™ unit.
Capitalised IT development expenditure is disclosed within Intangible assets as part of IT development and software. 
All costs capitalised within this category relate to information technology and, in general, are amortised over an economic 
life of five years. A new system was integrated and brought into use during 2020 and associated development costs were 
amortised over the contract term of two years. 
Intangible assets
Intangible assets acquired separately from third parties consist of software costs, including licence fees. These are 
recognised as assets, measured at cost and classified as part of IT development and software.
Internally generated intangible assets relate to IT development and are recognised as part of IT development and software. 
Refer to further details in the research and development accounting policy above. 
Intangible assets acquired as part of a business combination are recognised outside goodwill if the asset is separable 
or arises from contractual or other legal rights. They are recognised at their fair value at the date of acquisition and are 
subsequently amortised on a straight line basis over their estimated useful lives.
Following initial recognition, intangible assets are measured at cost at the date of acquisition less any amortisation and any 
impairment losses. Amortisation costs are included within Administrative expenses disclosed in the consolidated statement 
of comprehensive income.
Intangible assets are amortised over their useful lives as follows:
•	 IT development and software	
	
20% and 50% on cost, straight line
•	 Intangibles recognised upon acquisition:
	−Customer contracts	
	
	
20% on cost, straight line
	−Trademarks 	 	
	
	
33% on cost, straight line
Useful lives are examined on an annual basis and adjustments, where applicable, are made on a prospective basis.
Goodwill
Goodwill represents the excess of the consideration transferred over the fair value of the identifiable assets and liabilities 
of the acquiree at the date of acquisition. Goodwill on acquisitions of subsidiaries is included in intangible assets. Goodwill 
is not amortised but is tested annually for impairment, or if there is an indication of impairment, and is carried at cost less 
accumulated impairment losses. Impairment losses are not subsequently reversed.
Goodwill is allocated to cash-generating units (CGUs) for the purpose of impairment testing. The allocation is made to those 
CGUs or groups of CGUs that are expected to benefit from the business combination in which the goodwill arose. The units 
or groups of units are identified at the lowest level at which goodwill is monitored for internal management purposes. 
If the recoverable amount of an asset (or CGU) is estimated to be less than its carrying amount, the carrying amount of the 
asset (or CGU) is reduced to its recoverable amount. An impairment loss is recognised as an expense immediately.
Where an impairment loss subsequently reverses, the carrying amount of the asset (or CGU) is increased to the revised 
estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount 
that would have been determined had no impairment loss been recognised for the asset (or CGU) in prior years. A reversal 
of an impairment loss is recognised as income immediately.
Contingent consideration is recorded initially at fair value and classified as equity or a financial liability. Contingent 
consideration classified as equity is not remeasured, but contingent consideration classified as a financial liability is 
subsequently remeasured at fair value through profit or loss.

Goodwill continued
Adjustments to provisional fair values of identifiable assets and liabilities (and to estimates of contingent consideration) 
arising from additional information, obtained within the measurement period (no more than one year from the acquisition 
date), about facts and circumstances existing at the acquisition date, are adjusted against goodwill. Other adjustments 
to provisional fair values or changes in contingent consideration are recognised through profit or loss.
Impairment of tangible and intangible assets other than goodwill
At each reporting date, the Group reviews the carrying amounts of its property, plant and equipment and intangibles to 
determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, 
the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where the 
asset does not generate cash flows that are independent from other assets, the Group estimates the recoverable amount 
of the CGU to which the asset belongs.
The recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated 
future cash flows are discounted to their present value using a discount rate that reflects current market assessments of the 
time value of money and the risks specific to the asset for which the estimates of future cash flows have been adjusted.
An impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount.
Property, plant and equipment
Property, plant and equipment is stated at cost, net of accumulated depreciation and any accumulated impairment losses. 
Property, plant and equipment is initially recorded at cost. Such cost includes the cost of replacing part of the property, plant 
and equipment. When significant parts of property, plant and equipment are required to be replaced in intervals, the Group 
recognises such parts as individual assets with specific useful lives and depreciation. Pursuant to the acquisition of the meter 
installation businesses on 18 March 2016 certain internal costs to the Group are also capitalised where they are demonstrated 
as being directly attributable to bringing the meter assets into their usable condition.
Acquired development and construction rights together with directly attributable costs incurred in relation to the construction 
of the grid-scale battery storage sites are accounted for under IAS 16: Property, plant and equipment. These are recorded at 
cost and classified as part of Assets under construction within Property, plant and equipment. Whilst under construction no 
depreciation is recorded. 
All other repair and maintenance costs are recognised in the consolidated statement of comprehensive income as incurred. 
For each asset depreciation is calculated using the straight-line method to allocate its cost, net of its residual value 
if applicable, over its estimated useful life as follows:
•	 Freehold property 	
	2% 
•	 Short-leasehold property	
	Shorter of the lease term or 15% and 20% 
•	 Meter assets	
Smart meters and Industrial & Commercial meters 5%
	
ADM™ units 10%
	
Traditional meters to 1 July 2025
•	 Plant and machinery	
33% 
•	 Fixtures, fittings and equipment	 20% and 33% 
•	 Motor vehicles	
25% 
•	 Grid-scale assets	
Shorter of the lease term or 2.5% to 10%
Battery assets 10%
•	 Right-of-use assets	
Shorter of the asset’s useful life and the lease term
An item of property, plant and equipment and any significant part initially recognised is derecognised upon disposal 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 
consolidated statement of comprehensive income when the asset is derecognised. The asset’s residual values, useful lives 
and methods of depreciation are reviewed at each financial year end and adjusted prospectively, if appropriate.
See the Leases accounting policy for further details on the recognition and measurement of right-of-use assets 
under IFRS 16.

Inventories
Finished goods and consumables are stated at the lower of cost and net realisable value. Cost comprises direct materials 
and purchases of meter assets and ADM™ units at cost. Costs of purchased inventory are determined after deducting 
rebates and discounts. Net realisable value represents the estimated selling price for inventories in the ordinary course 
of business less the estimated costs necessary to make the sale. 
Cash and cash equivalents
Cash and cash equivalents in the consolidated statement of financial position comprises cash at bank and in hand and short-
term deposits with an original maturity of three months or less. For the purpose of the consolidated statement of cash flows, 
cash and cash equivalents consists of cash and short-term deposits as defined above, net of outstanding bank overdrafts.
Restricted cash
Restricted cash in the consolidated statement of financial position comprises amounts collected from customers on behalf 
of a third party, as part of a services arrangement, that have not yet been allocated. These monies are held in a trust 
account whilst awaiting allocation and, per the terms of the account, cannot be used by the Group to meet other short-term 
cash commitments. They have thus been disclosed separately on the statement of financial position.
Pension costs
The Group operates a defined contribution pension scheme for employees. The assets of the scheme are held separately from 
those of the Group. The annual contributions payable are charged to the consolidated statement of comprehensive income.
Share-based payments
IFRS 2 Share-based Payment has been applied to all grants of equity instruments. The Group issues equity-settled 
share-based payments to certain employees under the terms of the Group’s various employee share and option schemes. 
Equity-settled share-based payments are measured at fair value at the date of the grant. The fair value determined at the 
grant date of equity-settled share-based payments is expensed on a straight-line basis over the vesting period, based on 
an estimate of the shares that will ultimately vest. 
Share capital
Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new ordinary shares or options 
are shown in equity as a deduction from the proceeds.
Own share reserve
The Group offers a Share Incentive Plan for all employees and has established a trust to facilitate the delivery of SMS shares 
under this plan. The holdings of this trust include shares that have not vested unconditionally to employees of the Group. 
These shares are recorded at cost and are classified as own shares. The cost to the Company of acquiring these own shares 
held in trust is shown as a deduction from shareholders’ equity. 
Dividends
Dividend distributions to the Company’s shareholders are recognised in the accounting period in which the dividends are paid. 
Taxation
Tax currently payable is based on the taxable profit for the year and any adjustment to tax payable in respect of prior years. 
Taxable profit differs from accounting profit as reported in the consolidated statement of comprehensive income because 
it excludes items of income or expense that are taxable or deductible in other years and it further excludes items that are 
never taxable or deductible. The Group’s liability for current tax is measured using tax rates that have been enacted or 
substantively enacted by the reporting date.
Deferred tax is the tax expected to be payable or recoverable on temporary differences between the carrying amount 
of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable 
profit, and is accounted for using the balance sheet liability method. Deferred tax is recognised in respect of all temporary 
differences that have originated but not reversed at the balance sheet date, where transactions or events that result in 
an obligation to pay more tax in the future or a right to pay less tax in the future have occurred at the balance sheet date.
Deferred tax is measured at the tax rates that are expected to apply in the periods in which the asset or liability is settled based on 
tax rates (and tax laws) that have been enacted or substantively enacted at the balance sheet date. It is recognised in the income 
statement except when it relates to items recognised in other comprehensive income or directly in equity, such as share-based 
payments. In this case, the deferred tax is also recognised in other comprehensive income or directly in equity, respectively. 
Deferred tax assets are recognised to the extent that it is probable that future taxable profit will be available against which 
the temporary difference can be utilised. Their carrying amount is reviewed at each balance sheet date on the same basis.

Strategic report

Taxation continued
Deferred tax liabilities are recognised for all temporary differences, except in respect of:
•	 temporary differences arising from the initial recognition of goodwill or an asset or liability in a transaction that is not 
a business combination and at the time of the transaction affects neither the accounting profit nor taxable profit or loss; and
•	 temporary differences associated with investments in subsidiaries where the timing of the reversal of the temporary 
differences can be controlled and it is probable that the temporary difference will not reverse in the foreseeable future.
Deferred tax assets and liabilities are offset where there is a legally enforceable right to offset current tax assets and 
liabilities and where the deferred tax balances relate to the same taxation authority. Current tax assets and tax liabilities 
are offset where the entity has a legally enforceable right to offset and intends either to settle on a net basis, or to realise 
the asset and settle the liability simultaneously.
Standards and interpretations
New and amended standards adopted by the Group
The Group has applied the following standards and amendments for the first time for its annual reporting period 
commencing 1 January 2022:
Standard or interpretation 
 
Effective date
IFRS 3 (amendment)
Business Combinations Reference to the Conceptual Framework
1 January 2022
IAS 16 (amendment)
Property, Plant and Equipment – Proceeds Before Intended Use
1 January 2022
IAS 37 (amendment)
Provisions, Contingent Liabilities, Contingent Assets, Onerous 
Contracts – Cost of Fulfilling a Contract
1 January 2022
The amendments listed above did not have any material impact on the amounts recognised in prior periods or the current 
period and are not expected to affect future periods significantly. 
New standards and interpretations not yet adopted
Certain new accounting standards and interpretations have been published that are not mandatory for 31 December 2022 
reporting periods and have not been early-adopted by the Group. The amendments to IAS 12 Income Taxes, regarding 
deferred tax related to assets and liabilities arising from a single transaction, will apply to the Group as a lessee under 
IFRS 16. These amendments are effective for periods beginning on or after 1 January 2023 and their potential effects are 
under consideration. All other standards are not expected to have a material impact on the entity in the current or future 
reporting periods, or on foreseeable future transactions.

1 Segmental reporting
For management purposes, the Group is organised into three core divisions, as follows:
•	 Asset management, which comprises regulated management of gas and electric meters, ADM™ units and energy data 
assets within the UK;
•	 Asset installation, which comprises installation of domestic and I&C gas meters and electricity meters throughout the UK; and
•	 Energy management, which comprises the building and operation of grid-scale batteries, the provision of energy 
consultancy services and the management of distributed energy resources (DER).
For the purpose of making decisions about resource allocation and performance assessment, it is the operating results of 
the three core divisions listed above that are monitored by management and the Group’s chief operating decision-maker, 
being the SMS Board. It is these divisions, therefore, that are defined as the Group’s reportable operating segments.
Segment performance is mainly evaluated based on gross profit.

Inter-segment revenue relates to installation services provided by the asset installation segment to the asset management 
segment. 
Depreciation associated with meter assets in the asset management segment and grid-scale battery assets in the energy 
management segment has been reported within Cost of sales as these assets directly drive revenue (see note 3).
All material operations are based in the UK and revenue generated in the UK. Following the acquisition of Solo Energy 
Limited in 2019, a small minority of operations are based in the Republic of Ireland.
The Group has two major customers that each generated 10% or more of total Group turnover, as listed below by segment:

10 Impairment of goodwill continued
Additional goodwill of £737,000 has been recognised in the year on the acquisition of n3rgy Data Limited and is recognised 
in the Asset management CGU.
The Group tests goodwill for impairment annually or more frequently if there are indications that goodwill might be impaired. 
Goodwill is tested for impairment by comparing the carrying amount of each CGU, including goodwill, with the recoverable 
amount. The recoverable amounts are determined based on value-in-use calculations which require assumptions. The 
calculations use cash flow projections based on financial budgets approved by the Board covering a one-year period, 
together with management forecasts for a further four-year period. These budgets and forecasts have regard to historical 
performance and knowledge of the current market, together with the Group’s views on the future achievable growth and the 
impact of committed cash flows. Cash flows beyond this are extrapolated using the estimated growth rates stated below. 
The cash flows used in the value-in-use calculation for the asset management segment include all costs incurred in the 
provision of meter assets to energy suppliers, together with the initial installation. The cash flows used in the value-in-use 
calculation for the asset installation segment exclude installation costs incurred to fit an owned meter. For the purpose of 
the value-in-use calculation, these are instead allocated to the asset management segment, being the segment to which 
the corresponding revenues are allocated.
The annual impairment test was performed for the three CGUs identified above that have goodwill allocated to them. 
No evidence of impairment was found at the balance sheet date. 
The key assumptions used in the value-in-use calculations for those CGUs that have goodwill allocated to them are as follows:
•	 Perpetual growth rate – the terminal cash flows are extrapolated in perpetuity using a growth rate of 2.25% for asset 
management (2021: 2.25%) and 1.0% for asset installation and Solo Energy (2021: 1.0% for asset installation and Solo 
Energy). The rate of 2.25% applied to asset management is derived from historical Retail Price Index increases applied to 
the segment’s index-linked meter rentals. This is not considered to be higher than the average long-term industry growth 
rate. The rate of 1.0% applied to asset installation and Solo Energy is aligned to the Group's corporate forecast model and 
is lower than the rate applied to asset management as revenues in these segments are not always index-linked. 
•	 Discount rate – the discount rate is initially based on the weighted average cost of capital (WACC) which would be 
anticipated for a market participant investing in the Group. A specific discount rate is then calculated for each operating 
segment, taking into account the time value of money, the segment’s risk profile and the impact of the current economic 
climate. The pre-tax discount rates applied are 8.0%, 10.0% and 19.4% for asset management, asset installation and Solo 
Energy respectively (2021: 6.8% for asset management, 8.6% for asset installation and 18.2% for Solo Energy) and the 
post-tax discount rates applied are 6.0%, 7.5% and 15.0% for asset management, asset installation and Solo Energy 
respectively (2021: 5.5% for asset management, 7.00% for asset installation and 15.0% for Solo Energy). The risk premium 
assigned to the asset installation CGU reflects the shorter-term nature of the underlying revenues within this segment, as 
compared to the annually recurring revenue generated by an installed asset. The risk premium assigned to the Solo Energy 
CGU reflects the pre-revenue status of this part of the business, in which the underlying system is still undergoing 
development. 
Management has performed sensitivity analysis on the key assumptions both with other variables held constant and with 
other variables simultaneously changed. Management has concluded that there are no reasonably possible changes in 
the key assumptions that would cause the carrying amounts of goodwill to exceed the value in use for any of the CGUs.

1	 The reclassification of £4,071,000 within Assets under construction relates to costs previously recorded within Inventories at 31 December 2020. 
Meter assets
In 2021, meter asset acquisitions include the c.15,000 assets acquired as part of the Industrial & Commercial large-power 
half-hourly electricity business acquisition. See note 24 for details. 
Included within the closing Meter assets net book value of £429,712,000 (2021: £366,705,000) is £11,173,000 (2021: £16,246,000) 
relating to the traditional meter portfolio. In accordance with our accounting policy these assets will be written down to 
zero by 1 July 2025. In the 2022 consolidated financial statements the traditional meter portfolio generated £10,198,000 
(2021: £12,781,000) of revenue with a corresponding £4,383,000 (2021: £5,071,000) depreciation charge. As at 31 December 2022, 
£11,168,000 (2021: £11,787,000) of annualised recurring revenue arises from the owned traditional meter portfolio. 
The assets are secured by a bond and floating charge.

For the purpose of impairment testing the traditional meter asset portfolio recognised within “Meter assets” is assessed as a 
stand alone cash-generating unit (CGU) and its carrying amount is compared with the recoverable amount. See background 
information provided in the “Key sources of estimation uncertainty” section in the accounting policies. The recoverable 
amount is determined based on a value-in-use calculation, which uses the following key assumptions:
•	 estimated future cash flows from rental income, which decline based on the forecast for when meters are replaced;
•	 estimated future cash flows from termination income, which are derived using historical data and analysis around the risk 
of churn between contracted and non-contracted customers and the risk of non-recoverability once issued; and
•	 a pre-tax discount rate of 6.45%, which reflects the risk attached to the time value of these specific cash flows and is 
deemed to be best represented by the Group’s incremental cost of borrowing on the basis that cash flows are secured by 
the installed meter and the risk inherent in the decline of the cash flows is already accounted for through the assumptions 
detailed above.
The impairment test indicated that the value in use of the traditional meter assets CGU exceeded its carrying value and 
therefore no impairment has been recognised in the year to 31 December 2022. 
Management has performed sensitivity analysis on the key assumptions both with other variables held constant and with 
other variables simultaneously changed. Management has concluded that there are no reasonably possible changes in 
the key assumptions that would cause the carrying amounts of the traditional meter portfolio to exceed the value in use 
for either CGU.
No impairment on other meter assets was recognised in 2022 or 2021.

Trade receivables are non-interest-bearing and are generally on 30 to 90-day terms. Trade receivables due from related 
parties at 31 December 2022 amounted to £nil (2021: £nil).
Substantially all trade receivables are denominated in Sterling.
Accrued income, which is made up of unbilled receivables and contract assets, is presented net of any loss allowance and 
impairment, with amounts being invoiced periodically and customers being the same as those within trade receivables. 
The loss allowance for accrued income at 31 December 2022 was £1,156,000 (2021: £401,000) and the charge recognised 
in profit or loss during the year was £755,000.

The Group classifies non-current assets as held for sale if the assets are available immediately for sale in their present 
condition, management is committed to a plan to sell the assets under usual terms, it is highly probable that their carrying 
amounts will be recovered principally through a sale transaction rather than through continuing use and the sale is expected 
to be completed within one year from the date of the initial classification. 
Assets classified as held for sale are presented separately in the consolidated statement of financial position and are 
measured at the lower of their carrying amount and fair value less costs to sell. Property, plant and equipment are not 
depreciated once classified as held for sale.

The Group has a £420m revolving credit facility which matures in December 2025. Interest is payable at a rate of 1.85% over 
SONIA and 0.65% is payable on undrawn funds.
The loans drawn under the facility are all denominated in Pounds Sterling. The balance as at 31 December 2022 is stated net 
of £1,651,000 of unamortised transaction costs. 
No principal or interest was outstanding as at 31 December 2021 and the amount recognised as Bank loans was therefore nil. 
Unamortised transaction costs of £2,201,000 that would ordinarily be deducted from the carrying value of bank loans were 
therefore classified as Other assets (£550,000 was classified as current Other assets, with the balance of £1,651,000

The Group is required to restore the land leased as part of its grid-scale battery storage business, and certain leased 
warehouses, to the condition required by the terms and conditions of the lease at the end of the respective lease terms 
(which range between three to ten years for warehouses and 20 to 40 years for land). A provision has been recognised for the 
present value of the estimated expenditure required to carry out this restoration. These costs have been capitalised as part 
of the cost of right-of-use assets and are depreciated over the shorter of the term of the lease and the useful life of the 
assets. Provisions also include the estimated cost to decommission grid-scale batteries at the end of their life.

At 31 December 2022, the main rate of corporate tax applying to the profits of the Group was 19%. In the spring Budget 2021, 
the UK Government announced that from 1 April 2023 the corporation tax rate would increase to 25% (rather than remaining 
at 19%, as previously enacted). This new law was substantively enacted on 24 May 2021. Deferred taxes at the balance sheet 
date have been measured using these enacted tax rates and reflected in these financial statements.

Further, the UK Government announced legislation in respect of the ‘super-deduction’ for qualifying capital expenditure 
incurred during a two-year period commencing 1 April 2021. This new law was also substantively enacted on 24 May 2021. 
The Group has recognised an estimated permanent benefit of £2,294,000 on qualifying assets when calculating the tax 
charge for the current year, as well as a permanent benefit in respect of the prior year of £230,000.
The Group had unrecognised trading losses of £1,762,000 (2021: £1,456,000) in subsidiary undertakings at 31 December 2022. 
The Group also had unrecognised capital losses of £729,000 (2021: £729,000) in subsidiary undertakings at 31 December 2022. 
23 Financial risk management
The Board reviews and agrees policies for managing the risks associated with interest rate, credit and liquidity risk. 
The Group has in place a risk management policy that seeks to minimise any adverse effect on the financial performance 
of the Group by continually monitoring the following risks:
(a) Interest rate risk
The Group’s main interest rate risk arises from its floating rate bank loan. See note 18 for further details. 
There were no overdrafts at 31 December 2022 (2021: none) and the interest charge arising on lease liabilities does not 
represent a cash interest rate risk for the Group. 
The Group’s financial assets at 31 December 2022 comprise cash and trade receivables. The cash balance of £32,770,000 
(2021: £117,687,000) is a floating rate financial asset, but interest income is not typically material. 
Interest rate sensitivity
The following table shows how a change in interest rates applied to the average level of borrowings would have affected the 
Group’s interest cost and profit before tax:

basis points
(Decrease) in profit 
before tax
£’000
2022	
+100bps
(198)
2021	
+70bps
–
(b) Fair values of financial liabilities and financial assets
The Group’s bank loan is measured at amortised cost. For fair value disclosure purposes, the bank loan is considered to be a 
level 2 financial instrument on the basis that it is not traded in an active market. The fair values, based upon the market value 
or discounted cash flows of financial liabilities and financial assets held in the Group, were not materially different from their 
book values.
(c) Foreign currency risk
The Group’s exposure to the risk of changes in foreign exchange primarily arises from a single subsidiary, operating in Euros. 
With the exception of this entity, all of the Group’s operating activities are denominated in Pounds Sterling and, therefore, 
the Group’s overall exposure is not significant.
(d) Liquidity risk
The Group manages its cash in a manner designed to ensure maximum benefit is gained whilst ensuring security of 
investment sources. The Group’s policy on investment of surplus funds is to place deposits at institutions with strong credit 
ratings; this is considered to be institutions with a credit rating of AA– and above. Currently, all of the chosen investment 
institutions are in line with these criteria.

(e) Credit risk
The Group’s credit risk primarily arises from credit exposures to energy suppliers (our customers), including outstanding 
receivables, due to the Group trading with a limited number of companies, which are generally large utility companies 
or financial institutions. 
Credit risk is managed on a Group basis. For banks and financial institutions, only independently rated parties with a 
minimum rating of AA– are accepted. With regard to customers, the Group assesses the credit quality of the customer, 
considering its financial position, past experience and other factors. The Group does not expect, in the normal course of 
events, that debts due from customers are at significant risk. The Group’s maximum exposure to credit risk equates to the 
carrying value of cash and cash equivalents, trade and other receivables, contract assets and investments. The Group’s 
maximum exposure to credit risk from its customers is £44,682,000 (2021: £41,716,000), being the sum of the carrying value of 
trade receivables and accrued income, including contract assets, as disclosed within Trade and other receivables in note 14. 
The Group regularly monitors and updates its cash flow forecasts to ensure it has sufficient and appropriate funds to meet 
its ongoing operational requirements. 
Impairment of financial assets
The Group has two types of financial assets that are subject to IFRS 9’s expected credit loss model:
•	 trade receivables, which consist of billed receivables arising from contracts with customers, for the provision of meter asset 
installation, management and energy services; and
•	 accrued income, which consists of contract assets and unbilled receivables arising from contracts with customers.
While cash and cash equivalents, and debt investments held at amortised cost, are also subject to the impairment 
requirements of IFRS 9, the identified impairment loss was immaterial.
The Group applies the IFRS 9 simplified approach to measuring forward-looking expected credit losses, which uses a lifetime 
expected loss allowance for all trade receivables and accrued income, including contract assets.
To measure the ECL, trade receivables and accrued income have been grouped based on shared credit risk characteristics 
and the days past due. Accrued income relates to rights to consideration for performance, and other operating charges, 
before payment is due from customers, and consists of unbilled receivables and contract assets (see note 2 for details). 
These have substantially the same risk characteristics as the trade receivables for the same types of contracts. The Group 
has therefore concluded that the expected loss rates for trade receivables are a reasonable approximation of the loss rates 
for accrued income.

Financial statements
Governance
Strategic report

23 Financial risk management continued
(e) Credit risk continued
The Group has established a provision matrix based on the payment profiles of sales, over the most recent twelve-month 
period that is an appropriate representation of loss patterns, and the corresponding historical credit losses experienced 
within this period. The historical loss rates are adjusted to reflect current and forward-looking information that might affect 
the ability of customers to settle the receivables, including macroeconomic factors as relevant. In calculating the loss rates, 
certain historical losses arising from specific circumstances with customers have been removed where these are not 
indicative of future loss patterns. 
During the second half of 2021, the global energy market suffered from unprecedented increases in wholesale gas prices, 
creating significant volatility within the UK energy market and leading to a number of independent energy suppliers entering 
administration and exiting the market. This crisis notably impacted the smaller independent energy suppliers and, as a 
result, management did not increase the expected loss rates for the trade receivables portfolio as a whole. Instead, a subset 
of trade receivables has been identified as having a potentially elevated credit risk, due to a greater risk of administration as 
a direct consequence of the crisis. This subset of trade receivables has been provided for on a specific basis and has resulted 
in an additional £0.2m impairment loss in the year. Given the continued and changing uncertainty regarding the impact of 
this crisis on customer default risk, management will continue to monitor the situation and reassess its ECL at each reporting 
period end accordingly. 
On that basis, the loss allowance at 31 December 2022 was determined as £4,182,000 (2021: £4,370,000) for trade 
receivables and accrued income. A reconciliation of these balances is provided as follows:

The overall loss allowance has decreased at 31 December 2022. Whilst the crisis in the energy market has given rise to 
an additional impairment loss in the year, as detailed above, only one energy supplier entered administration during 2022 
in comparison to the high number of insolvencies seen in the prior year. 
Total net impairment losses on financial and contract assets were £563,000 in 2022 (2021: £2,964,000). Of this amount, 
£563,000 (2021: £2,964,000) relates to amounts arising from trade receivables and accrued income. 
Fair value
There is no material difference between the book value and the fair value of any financial asset or liability.
(f) Capital management
Capital is the equity attributable to the equity holders of the parent. The primary objective of the Group’s capital 
management is to ensure that it maintains a strong credit rating and healthy capital ratios in order to support its business 
and maximise shareholder value. The Group manages its capital structure, and makes adjustments to it, in light of changes 
in economic conditions. To maintain or adjust the capital structure, the Group may adjust the dividend payment to 
shareholders, sell assets, return capital to shareholders or issue new shares.
The Group monitors capital on the basis of a leverage ratio. This ratio is calculated as net debt divided by pre-exceptional 
EBITDA. Net debt is calculated as total borrowings less cash. Pre-exceptional EBITDA is calculated as operating profit 
before any significant exceptional items, interest, tax, depreciation and amortisation.
The objective of SMS’s strategy is to deliver long-term value to its shareholders whilst maintaining a balance sheet structure 
that safeguards the Group’s financial position. Under the Group’s enhanced dividend policy, SMS declared a 27.5p per share 
dividend in respect of FY 2021 and proposes a 30.25p per share dividend in respect of FY 2022. The Group’s long-term 
index-linked cash flows from its existing asset base are able to support an intended annual increase of 10% in dividends for 
each of the financial years FY 2022, FY 2023 and FY 2024. This results in a more predictable return to shareholders and 
reflects the forecast growth of the business over and above RPI in that period. The Group’s strong liquidity position supports 
the funding of its contracted smart meter order pipeline, which will further add to its long-term index-linked cash flows.

On 25 May 2022, the Group acquired 100% of the issued share capital of n3rgy Data Limited, a data software company, for 
cash consideration of £1.4m and additional contingent consideration subject to the company achieving certain performance 
targets. n3rgy Data Limited’s software enables and facilitates the use of energy consumption, generation and tariff data 
from smart meters. The acquisition is expected to enhance and accelerate the Group’s capabilities in smart energy data 
solutions and is reported in the Group’s asset management segment.

If n3rgy Data Limited’s EBITDA over a five year earn-out period exceeds a threshold, then contingent consideration 
becomes payable based on the amount by which the EBITDA exceeds the threshold. The minimum payment is therefore nil 
and the maximum payment is unlimited. The fair value of the contingent consideration at the acquisition date of £588,000 
represents the estimated most likely pay-out based on management's future forecast of future trading (level 3) discounted 
at the Group’s incremental borrowing rate.
The goodwill is mainly attributable to synergies and the opportunity to accelerate growth of the Group’s data business. 
Goodwill will not be deductible for tax purposes.
The acquisition contributed £127,000 to the Group’s revenue and reduced the Group’s profit before tax by £406,000 between 
the date of acquisition and 31 December 2022.
If the acquisition had been completed on 1 January 2022, the Group’s revenue would have been £135,591,000 and profit 
before tax would have been £15,786,000 for the year ended 31 December 2022.
Acquisition-related costs of £20,000 have been included as part of exceptional Administrative costs in the consolidated 
statement of comprehensive income. 
Year ended 31 December 2021
On 6 April 2021 the Group acquired a portfolio of c.15,000 Industrial & Commercial large-power half-hourly electricity meters 
from a third party. The Group also took ownership of the Meter Operator (MOP) and data service contracts associated with 
a portfolio of electricity meters. This is reported through the Group’s asset management segment. 
As part of the transaction, a workforce was transferred with the skills, knowledge and experience to generate revenues from 
the assets and contracts acquired, and potentially grow the acquired business for the Group. Such a workforce meets the 
definition of a substantive process under IFRS 3. On the basis that the Group has obtained inputs, a substantive process and 
outputs, management has concluded that the acquisition meets the definition of a business combination and should be 
accounted for as such under IFRS 3. 
Purchase consideration consisted of cash only. Total cash paid was £8,433,000.

No contingent assets or liabilities were acquired. The customer contracts acquired were valued using a multi-period excess 
earnings method, which assesses the present value of the after-tax cash flows attributable only to these contracts.
The goodwill is attributable to the opportunity to grow this part of the business for the Group. Goodwill will not be deductible 
for tax purposes.
For the year ended 31 December 2021, the acquired business contributed a net profit before taxation of £1.7m to the Group. 
If the acquisition had occurred on 1 January 2021, consolidated pro-forma profit for the year ended 31 December 2021 would 
have been approximately £2.2m. 
Acquisition-related costs of £0.3m have been incurred to date, including transaction costs and mobilisation costs to 
integrate the newly-acquired business into the Group, and have been included as part of exceptional Administrative costs in 
the consolidated statement of comprehensive income.

All seven companies report in British Pounds Sterling. The acquisitions enable SMS to obtain control over the rights required 
to develop and commission seven grid-scale battery storage sites, totalling 320MW, as part of the Group’s strategy of 
investment in CaRe assets. Grid-scale battery storage is reported through the Group’s energy management segment and 
is a key asset class required by the UK energy system to provide flexibility services to balance the grid and support the 
continued introduction of more intermittent renewable generation. 
In respect of one of the companies, deferred consideration of £274,000 is payable in cash upon energisation (when the 
grid-scale battery storage asset is connected to the grid). Deferred consideration of a further £600,000 is payable on the 
execution of certain property deeds. The payments have been measured at fair value at the acquisition date, ignoring the 
impact of discounting on the basis that the anticipated payment date is within 24 months of the current reporting date and 
management consider the impact of discounting over this period to be immaterial.
Management has concluded that these acquisitions do not meet the definition of a business combination under IFRS 3 on 
the basis that no substantive processes have been transferred. Therefore, these transactions have been accounted for as 
acquisitions of a group of assets. No goodwill thus arises on the transactions. 
The individual assets and liabilities acquired have been identified and the cost of the transactions has been allocated to the 
assets acquired, and liabilities assumed, based on their relative fair values at the date of purchase as follows:

The majority of the value gained from acquiring the sites is attributable to development and construction rights

The majority of the value gained from acquiring the four sites is attributable to development and construction rights and 
therefore a significant portion of the total cost of the transaction has been allocated to Assets under construction due to 
its higher fair value relative to the other net assets acquired.
Transaction costs of £0.2m were incurred and have been capitalised as a component of the cost of the assets acquired, 
classified as part of Assets under construction within Property, plant and equipment.

28 Share-based payments
(a) Employee option plans 
The Group operates the Unapproved Share Option Plan (the ‘Unapproved Plan’) and the Long-Term Incentive Plan (LTIP).
The Unapproved Plan is open to any employee, including Executive Directors. Participants are granted options which, 
except in certain specified circumstances, only vest if certain performance conditions are met and the employee is still in 
service five years from the date of grant. The performance conditions for awards are based on market capitalisation and 
individual performance targets. Once vested, the options remain exercisable for a period of up to ten years from the date 
of grant. The exercise price of the options is determined by the Directors but shall not be less than the closing price at which 
the Company’s shares are traded on the date of grant. 
The LTIP is open to senior employees. Participants are granted nil-cost options which are subject to performance conditions 
and remaining employed up to the vesting date. The performance conditions are based on the total shareholder return and 
meeting financial and non-financial targets over a three-year performance period. The vesting period varies from three to 
five years. Once vested, the options remain exercisable for a period of up to ten years from the date of award.

(a) Employee option plans continued
In January 2022, the Remuneration Committee assessed performance of the first four tranches of the 2018 awards and the 
first two tranches of the 2020 awards under the Unapproved Plan against vesting criteria. These awards did not meet the 
market capitalisation targets set when they were originally granted. The Remuneration Committee exercised the discretion 
available to it under the plan and, after taking into account a range of factors, concluded that these awards would vest at 
95% of the maximum. This has been accounted for as a modification of the awards. In accordance with IFRS 2, the options 
were valued as at the date of modification based on the original terms using a Monte Carlo simulation, and based on the 
modified terms using the Black-Scholes model. The incremental fair value granted as a result of the modifications was 
£1,067,000, all of which was recognised as an expense in 2022.
The expense recognised in 2022 for all options, including the effect of the modifications, is £2,262,000 (2021: £563,000).
(b) Share Incentive Plan (SIP)
The Company introduced the SIP in October 2014. All employees of the Group (including Executive Directors) are eligible 
to participate in the SIP. Participants may each acquire Partnership Shares worth up to £1,800 per year from their pre-tax 
earnings at market value. The Company awards participants one Matching Share for each Partnership Share which they 
acquire. Dividends received on shares held in the SIP are reinvested to acquire Dividend Shares at market value. Matching 
Shares may be forfeited if the participant disposes of the corresponding Partnership Shares or leaves the employment 
of the Group within three years of the award date.
The table below shows the number of shares held in the SIP at the beginning and end of the year.

The SIP is administered by the Smart Metering Systems SIP Trust (the ‘Trust’). To the extent sufficient shares are not already 
held by the Trust, Matching Shares awarded by the Trust to employees are acquired in the market prior to the award. 
Matching Shares held by the Trust which have not yet vested unconditionally at the end of the reporting period are shown 
as own shares in the financial statements. 
The fair value of the Matching Shares at the award date is equal to the share price at the award date. The weighted average 
fair value per share of the Matching Shares awarded during 2022 was approximately £8.02 per share (2021: £8.18). The total 
fair value of Matching Shares awarded is recognised over the three-year period starting on the respective award dates.
The expense recognised in 2022 for all Matching Shares is £350,000 (2021: £278,000). No expense is recognised for the 
Partnership Shares and Dividend Shares because the participants pay full market value for these shares.
29 Other reserve
This is a non-distributable reserve that initially arose by applying merger relief under section 612 of the Companies Act 2006 
to the shares issued in 2009 in connection with the Group restructuring. Additionally, the premium of £4,189,000 and 
£1,115,000 arising on the issue of shares as part of the acquisitions of CH4 Gas Utility and Maintenance Services Limited 
(‘CH4’), Trojan Utilities Limited (‘Trojan’) and Qton Solutions Limited (‘Qton’) has been credited to this reserve.

Strategic report

The parent company financial statements of Smart Metering Systems plc (the ‘Company’) for the year ended 31 December 
2022 were authorised for issue by the Board of Directors on 14 March 2023 and the balance sheet was signed on the Board’s 
behalf by Gail Blain. Smart Metering Systems plc is a public limited company limited by shares and incorporated and 
domiciled in Scotland, with its registered office at 2nd Floor, 48 St. Vincent Street, Glasgow G2 5TS. The Company’s ordinary 
shares are traded on AIM.
1 Parent company accounting policies
Basis of accounting
These financial statements are the first financial statements of the parent Company to be prepared under FRS 101. The 
financial statements of the parent Company for the year ended 31 December 2021 were prepared under FRS 102. The date 
of transition to FRS 101 is 1 January 2021. As a result of the transition to FRS 101 the Company’s amounts owed by Group 
undertakings of £407,125,000 (2021: £444,828,000) have been reclassified from current to non-current assets as the amounts 
owed are not expected to be settled within 12 months after the reporting period. There is no further impact on the previously 
reported results for the parent Company for the year ended 31 December 2021 or for the current year’s results arising from 
the transition to FRS 101. The financial statements are prepared under the historical cost convention. The Company took 
advantage of the deemed cost exemption to carry over investments carried at cost at the previous GAAP carrying amount.
The accounting policies of the parent Company financial statements follow those policies which apply in preparing the 
consolidated financial statements for the year ended 31 December 2022. The financial statements are prepared in Sterling 
and are rounded to the nearest thousand Pounds (£’000).
The following exemptions from the requirements of IFRS have been applied in the preparation of these financial statements, 
in accordance with FRS 101:
•	 Paragraphs 45(b) and 46 to 52 of IFRS 2, ‘Share-based payment’ (details of the number and weighted average exercise 
prices of share options, and how the fair value of goods or services received was determined).
•	 IFRS 7, ‘Financial instruments: Disclosures’.
•	 Paragraphs 91 to 99 of IFRS 13, ‘Fair value measurement’ (disclosure of valuation techniques and inputs used for fair value 
measurement of assets and liabilities).
•	 Paragraph 38 of IAS 1, ‘Presentation of financial statements’ – comparative information requirements in respect of 
paragraph 79(a)(iv) of IAS 1.
•	 The following paragraphs of IAS 1, ‘Presentation of financial statements’:
	−10(d) (statement of cash flows);
	−16 (statement of compliance with all IFRS);
	−38A (requirement for minimum of two primary statements, including cash flow statements);
	−38B–D (additional comparative information);
	−111 (cash flow statement information); and
	−134–136 (capital management disclosures).
•	 IAS 7, ‘Statement of cash flows’.
•	 Paragraphs 30 and 31 of IAS 8, ‘Accounting policies, changes in accounting estimates and errors’ (requirement for the 
disclosure of information when an entity has not applied a new IFRS that has been issued but is not yet effective).
•	 Paragraph 17 of IAS 24, ‘Related party disclosures’ (key management compensation).
•	 The requirements in IAS 24, ‘Related party disclosures’, to disclose related party transactions entered into between two 
or more members of a group.
Disclosure of auditor remuneration for non-audit fees is not given in the individual financial statements as the Group 
accounts are required to comply with regulation 5(1)(b) of the Companies (Disclosure of Auditor Remuneration and 
Liability Limitation Agreements) Regulations 2008 and present the information on a consolidated basis.
The Company is a guarantor in respect of the Group’s revolving credit facilities.

Going concern
Based on the current projections and facilities in place, the Directors consider it appropriate to continue to prepare 
the financial statements on a going concern basis.
Investments 
Investments in subsidiary undertakings are stated in the balance sheet of the Company at cost, or nominal value of the 
shares issued as consideration where applicable, less provision for any impairment in value. 
Share-based payments
The grant by the Company of options and share awards over its equity instruments to the employees of subsidiary 
undertakings in the Group is treated as a capital contribution. The fair value of employee services rendered, measured 
by reference to the grant date fair value, is recognised over the vesting period as an increase to the investments in subsidiary 
undertakings, with a corresponding credit to equity in the Company financial statements. The credit to equity is recognised 
within Other reserves, as these amounts are non-distributable at the Company level.

During 2022 and 2021, a number of subsidiary companies granted options and share awards to their employees over the shares 
of SMS. For accounting purposes, these grants are recorded as investments by the Company in its subsidiary undertakings.
Investments in subsidiaries are assessed annually to determine if there is any indication that any of the investments might be 
impaired. There were no material indicators of impairment at 31 December 2022 and therefore no impairment charge has 
been recognised in the year ended 31 December 2022. 
Subsidiary undertakings
