STRATEGIC REPORT 

The Directors of Northumbrian Water Group Limited (NWG or the Company) are pleased to present their Strategic Report 
on  the  affairs  of  the  Group  and  Company,  along  with  their  Directors’  Report,  the  Independent  auditor’s  report  and  the 
audited financial statements for the year ended 31 March 2018. 

Principal activities 

Northumbrian Water Group Limited 
NWG  owns  a  number  of companies  which,  together  with  NWG, form  the  Group.   The  emphasis  given  to  Northumbrian 
Water Limited (NWL), throughout this report, reflects its importance to the overall performance of the Group, however the 
Group’s other operations also deliver a significant contribution to the overall reported performance. 

Northumbrian Water Limited 
NWL’s principal activities comprise the supply of potable and raw water in both the north east and south east of England 
and the collection, treatment and disposal of sewage and sewage sludge in the north east of England. 

Water and wastewater contracts 
NWG holds investments in a number of companies which hold and operate water and wastewater contracts in Scotland, 
the  Republic  of  Ireland  and  Gibraltar.    NWG  also  controls  a  farm  based  anaerobic  digestion  plant  in  West  Yorkshire, 
England. 

Cautionary statement 
This  report  contains  certain  statements  with  regard  to  the  future  operations,  performance  and  financial  condition  of  the 
Group.   By their nature, these statements involve uncertainty, since future events and circumstances can cause results 
and developments to differ materially from those forecast.  Such statements reflect knowledge and information available 
at the date of preparation of this report and the Company undertakes no obligation to update such statements.  Nothing in 
this  report  should  be  construed  as  a  profit  forecast.    Certain  regulatory  performance  data  contained  in  this  report  is 
subject to regulatory audit. 

Business overview 
NWG is the holding company of NWL and a number of other companies, as reported above. 

NWL is one of the ten regulated Water and Sewerage Companies (WASCs) in England and Wales, operating in the north 
east of England, trading as Northumbrian Water, and in the south east of England, trading as Essex & Suffolk Water.  In 
the  north  east,  the  business  comprises  the  supply  of  both  potable  and  raw  water  and  the  collection,  treatment  and 
disposal  of  sewage  and  sewage  sludge,  serving  approximately  2.7  million  people.    In  the  south,  NWL  supplies  water 
services to approximately 1.5 million people in Essex and approximately 0.3 million in Suffolk. 

At the balance sheet date, the Company’s ultimate parent undertaking and controlling party was CK Hutchison Holdings 
Limited (CKHH), a company listed on the Hong Kong Stock Exchange. 

Regulatory and legislative developments 
NWL operates within a strict regulatory environment.  The Water Services Regulation Authority (Ofwat) regulates prices 
and  levels  of  customer  service,  while  the  Drinking  Water  Inspectorate  (DWI)  monitors  drinking  water  quality  and  the 
Environment  Agency  (EA)  covers  environmental  protection.    NWL’s  customers’  interests  are  represented  by  the 
Consumer Council for Water. 

NWL is well advanced in planning for the submission of its business plan to Ofwat for the 2020-2025 price review period.  
NWL have been on a journey over recent years from simply consulting with its customers, to active customer participation 
and co-creation. This deeper engagement with customers has been fundamental to the development of its future plans. 
NWL will continue to set stretching targets in line with its national leader vision which will deliver further service benefits to 
customers and the wider environment and communities in which it operates. 

NWL opted to exit the retail market on 1 April 2017 and transfer its non-household (NHH) customers to NWG Business 
Limited (NWGB), another NWG subsidiary.  This decision was taken to allow NWL to demonstrate transparently that, as a 
wholesaler, it will work with all retailers on an equal basis and it will continue to provide excellent wholesale services to all. 

Following market opening, Anglian Water Group Limited and NWG agreed to establish a joint venture and to transfer their 
entire shareholdings in their non-household retail (NHH) subsidiaries, Anglian Water Business (National) Limited (AWBN) 
and  NWGB  respectively,  to  a  joint  venture  vehicle,  Wave  Ltd  (Wave)  once  all  relevant  conditions  were  satisfied.    The 
transfers to Wave were executed on 31 August 2017.

STRATEGIC REPORT (continued) 

Business objectives 
The  vision  of  the  Directors  of  NWG  is  for  the  Group  companies  to  continue  to  deliver  value  to  customers  and  other 
stakeholders by focussing on their core competencies of water and wastewater management. 

Performance measures 
NWL uses a balanced scorecard of Key Performance Indicators (KPIs), reflecting its strategic themes.  These are internal 
measures set at stretching levels so as to drive year on year performance improvements on a path to deliver its ‘national 
leader’  vision.    This  means  that  they  are  often  more  stretching  than  the  regulatory  Performance  Commitments.  
Achievement against the balanced scorecard targets accounts for up to 90% of the annual bonuses of NWL’s Executive 
Leadership Team (ELT), with a further 10% available for the achievement of personal targets.   

The following table details actual performance against the KPI targets and future targets.  Targets which are measured on 
a  calendar  year  basis,  denoted  by  C  in  the  table,  reflect  the  performance  period  January  to  December  2017.    Targets 
which are measured on  a regulatory year basis, denoted by R in the table, reflect the performance period April 2017 to 
March 2018.

STRATEGIC REPORT (continued) 

Performance measures (continued) 
NWL  remains  committed  to  delivering  an  unrivalled  customer  service  and  to  be  the  national  leader  in  the  provision  of 
sustainable water and wastewater services.  To achieve ‘national leader’ status, NWL’s targets are often more stretching 
than the regulatory performance commitments.  It has made further progress in achieving ‘national leader’ status over the 
year and remains at the forefront of performance in the industry. 

Customers remain at the heart of NWL’s business, with customer satisfaction remaining extremely high in the year.  NWL 
continues its journey from customer consultation to deep customer participation, with customers co-creating strategy and 
approach to customer service, levels of performance commitments and how investments are made. 

In  NWL’s  water  business,  NWL  continues  to  provide  a  reliable  supply  of  clean  water,  maintaining  its  industry  leading 
performance  on  lowest  interruptions  to  supply  along  with  100%  security  of  supply.    In  spite  of  the  very  challenging 
weather conditions  in  late  February  2018, NWL kept the  water flowing  to  customers and  kept leakage  levels broadly  in 
line with performance targets for the year. 

The quality of the water NWL produces remains exceptionally high, with further progress made in driving down instances 
of  discolouration  and  taste  and  odour  complaints  from  customers.    NWL  continues  to  take  an  active  catchment 
management approach to improving the quality of water, working collaboratively with a number of partners to improve this 
position further. 

In the wastewater business of NWL, sewer flooding incidents continue to reduce, with a number of innovative approaches 
and  award  winning  campaigns.    In  the  wider  environment,  the  bathing  waters  in  NWL’s  north  east  operating  region 
continue to meet the required standard.  NWL continues to support the delivery of housing across the region, and work 
with local authorities, developers and land owners to unlock strategic housing sites. 

In  respect  of  renewable  energy,  NWL  remains  the  first  and  only  wastewater  company  in  the  UK  to  use  100%  of  the 
sludge  remaining  after  sewage  treatment  to  produce  renewable  energy  at  two  thermal  hydrolysis  advanced  anaerobic 
digestion (AAD) plants.  At one of these plants, NWL also cleans and transforms the biogas from the AAD process into 
biomethane  for  injection  to  the  gas  distribution  network.    In  addition,  solar  arrays  at  various  operating  sites  and 
opportunities for industrial scale energy storage are ongoing, which continue to contribute to NWL’s carbon management 
plan aim to reduce greenhouse gas emissions by 35% by 2020. 

The  Health  and  Safety  (H&S)  of  our  employees  and  contractors  is  a  responsibility  that  the  Group  takes  very  seriously.  
NWL  has  developed  a  comprehensive  ‘safety  culture’  to  increase  awareness  of  risk  and  encourage  employees  to  see 
safety as absolutely central to everything it does. NWL’s new company-wide campaign ‘Everyone home safe every day’ is 
reinforcing the safety message  across all  NWL teams.   NWL is certified  under OHSAS 18001  Occupational Health and 
Safety Systems and received a gold award from the Royal Society for the Prevention of Accidents (RoSPA) for the sixth 
consecutive  year.   The RoSPA Gold  Award  recognises organisations  which have achieved  a high  level  of performance 
and demonstrated well developed occupational H&S management systems and culture.  

The Group has continued to ensure that its people are fairly treated and we proactively promote diversity and inclusion to 
reap the benefits of a diverse workforce. NWL’s equal opportunity policy seeks to ensure that all current employees and 
potential employees are treated with respect. Job applications are welcomed from all parts of the community and it is the 
intention that all job applicants and employees are treated equally, regardless of their age, ability, marital or partnership 
status,  race,  religion  or  belief,  gender  or  sexual  orientation.  Employment  applications  are  welcome  from  people  with 
disabilities  and,  where  existing  employees  develop  disabilities,  they  are  supported  to  remain  in  employment,  wherever 
practicable,  by  providing  appropriate  adjustments  to  their  roles  and/or  effective  redeployments.  Occupational  health 
physicians assist this process with professional medical advice.  NWL recognises the importance of gender balance and 
is  committed  on  encouraging  more  women  to  join  NWL  and  develop  their  careers  in  the  water  industry.    It  is  actively 
partnering with other organisations and inclusion networks to promote diversity in science and engineering.  

We put great effort into creating an environment where our people are encouraged to engage and perform to the best of 
their  ability.  NWL  engages  with  its  employees  through  the  Employee  Relations  Framework  and  through  a  range  of 
communication  channels  including  annual  director  roadshows,  structured  team  talk  briefings  every  two  months,  our 
weekly H2info ebulletin, and digital tools such as the intranet and Yammer. 

The  Group  remains  dedicated  to  building  strong  relationships  with  the  communities  we  serve  and  we  ensure  that 
corporate responsibility  is  embedded  in  the  business.   We work with  partners across sectors  at a  range  of levels, from 
making  sure  we  provide  effective  grassroots  support  to  a  large  number  of  organisations  in  our  community,  to  a  small 
number of larger strategic flagship partners co-delivering with us in line with our vision and values.

STRATEGIC REPORT (continued) 

Performance measures (continued) 
One  of  the  highlights  for  NWL  in  2017/18  was  the  inaugural  Innovation  Festival  where  over  1,000  people  were  hosted 
over the week-long event  with the aim of finding  ways to address environmental and social issues that affect everyone. 
The  event  saw  employees  engaging  with  customers,  other  water  companies  and  some  world  class  partners  who  are 
leading in their fields. 
Financial performance and structure 

Group structure 
In addition to NWL, NWG has one other direct subsidiary; NWG Commercial Solutions Limited, which acts as a holding 
company for  other non-regulated  trading  companies.   NWGL also  directly  owns 50%  of a joint venture company, Wave 
Ltd, which carries out NHH retail activities in England and Scotland. 

In the Directors’ opinion, CKHH, a company listed on the Hong Kong Stock Exchange, is the ultimate parent undertaking 
and controlling party.  The chart below shows the structure of the Group and its ownership up to CKHH.  The chart shows

Financial performance 
In addition to the balanced scorecard, the Group uses a range of financial indicators to monitor performance, which focus 
on the financial covenants underpinning the Group’s private placement and committed bank facilities at NWL, which are 
reported to each Board meeting.  These financial KPIs, shown below, remained better than the target for the year.

Notes: 
1.  Regulatory Capital Value (RCV) at 31 March 2018 was £4,182.2 million (2017: £4,014.2 million). 

The  Group’s  gearing  has  increased  marginally  from  72.6%  to  72.9%,  with  net  debt  growing  at  4.6%  which  was  slightly 
ahead of RCV at 4.2%.  Gearing at NWL decreased from 64.7% to 62.5%, also remaining well within target. 

NWG 
Revenue for the year ended 31 March 2018 was £871.2 million (2017: £853.7 million).  Water and sewerage charges at 
the Group’s principal subsidiary, NWL, increased by a ‘K factor’ of 0.4%, plus RPI of 2.2%, which was applied from 1 April 
2017.    Income  from  the  Group’s  continuing  water  and  wastewater  contracts  continue  to  increase  in  line  with  the 
provisions of the relevant contracts. 

Operating costs are £519.4 million for the year ended 31 March 2018 (2017: £490.3 million), which principally  reflected 
movements at NWL, on an underlying basis, which are detailed below.  Profit on ordinary activities before interest for the 
year ended 31 March 2018 was £351.8 million (2017: £363.4 million). 

Net interest payable was £258.3 million for the year ended 31 March 2018 (2017: £281.4 million), including £113.7 million 
(2017: £113.7 million) on shareholder loan notes.  The decrease of £23.1 million was principally due to a favourable mark 
to  market  movements  on  the  fair  value  of  financial  instruments  compared  to  the  prior  year,  coupled  with  the  impact  of 
lower  RPI  on  index-linked  debt  accretion  and,  in  the  prior  year,  the  acceleration  of  interest  charges  related  to  the  buy 
back of £120 million of bonds which were due to mature in October 2017. 

Profit  on  ordinary  activities  before  tax  for  the  year  ended  31  March  2018  was  £91.2  million  (2017:  £83.2  million).   The 
current tax charge for the year ended 31 March 2018 was £16.8 million (2017:£14.8 million). The increase mainly reflects 
a  charge  in  relation  to  Action  4  of  the  OECD's  Base  Erosion  and  Profit  Shifting  (BEPS)  project  (see  note  8(e)  to  the 
accounts)  offset  by  a  fall  in  taxable  profit  mainly  due  to  derivative  movements  which  are  disregarded  for  tax  purposes, 
and a reduction in the tax rate to 19% (2017: 20%). Deferred tax for the year ended 31 March 2018 was a charge of £1.2 
million (2017: credit of £21.7 million). The net change from last year of £22.9 million mainly reflects the absence of any 
restatement  of  deferred  tax  liabilities  in  2018  (as  no  further  cuts  in  the  rate  of  UK  corporation  tax  have  been  enacted), 
offset by a deferred tax credit in relation to BEPS Action 4. Further details of the net tax charge are provided in note 8 to 
the financial statements.  Profit after tax from continuing operations for the year ended 31 March 2018 was £73.2 million 
(2017: £90.1 million). 

Total  fixed  asset  additions  for  the  Group  for  the  year  ended  31  March  2018  was  £261.5  million  (2017:  £227.4  million), 
representing capital investment to maintain and enhance the Group’s asset base. 

NWL 
Revenue, including internal NHH revenue to NWGB, was £834.6 million for the year ended 31 March 2018 (2017: £822.3 
million).    This  reflects  an  increase  in  wholesale  charges,  set  in  line  with  the  revenue  allowance  from  the  Final 
Determination (FD) of price controls for 2015-2020, which increased by a ‘K factor’ of 0.4% plus RPI of 2.2%, less the loss 
of NHH retail revenue, as a consequence of NWL exiting the NHH retail market, which contributed £8.9m revenue in the 
prior year. 

Operating  costs,  including  capital  maintenance  costs  for  the  year  ended  31  March  2018  were  £489.4  million  (2017: 
£456.6  million).    The  prior  year  costs  included  an  exceptional  credit  of  £10.7  million  relating  to  the  settlement  of  an 
outstanding  appeal  on  business  rates,  explained  in  more  detail  in  note  3.  Underlying  costs,  excluding  the  exceptional 
item,  have  increased  by  £22.1  million  (4.7%)  in  the  year.  This  primarily  reflects  significant  step  change  increases  in 
NWL’s  water  cumulo  rating  valuation  (£11.3  million)  and  a  change  to  the  structure  of  abstraction  charges  in  the  NW 
region (£6.9 million), along with increased energy costs, mostly through increased environmental levies (£3.2 million).

Financial performance (continued) 

STRATEGIC REPORT (continued) 

NWL (continued) 
Other upward  cost  pressures, through inflation and  capital  investment, have  been mitigated  by cost  efficiencies.  During 
the year, NWL invested £0.7 million (2017: £0.9 million) in research and development. 

Profit on ordinary activities before interest for the year ended 31 March 2018 was £345.2 million (2017: £365.7 million). 
Capital investment for the year ended 31 March 2018 was £260.7 million (2017: £225.2 million), reflecting around £174.0 
million investment for the maintenance of NWL’s asset base to ensure the continued provision of sustainable water and 
wastewater services and continued investment in its sewer network to reduce the risk of sewer flooding. 

Water and wastewater contracts 
The Group’s water and wastewater contracts in Scotland, the Republic of Ireland and Gibraltar are all performing well and 
are  in  line  with  expectations.    Revenue  for  the  contracts  was  £32.2  million  for  the  year  ended  31  March  2018  (2017: 
£30.5 million).  Profit on ordinary activities before interest was £2.7 million (2017: £1.6 million). 

The  Irish based  Coffey Northumbrian Limited  joint venture (CNL)  was  awarded  two framework contracts by  Irish Water 
(IW). The first framework was for water network management and it covered the south-east and south-west regions. The 
second  framework  was  regional  new  connections  and  it  covered  the  midlands  region.  The  development  of  these 
framework contracts by IW has been slower than anticipated, although the contracts are expected to deliver against plan. 
Additionally,  CNL  was  awarded  a  design,  build,  and  operate  (DBO)  contract  by  IW  for  the  Tubbercurry,  Grange, 
Strandhill,  and  Ballinafad  wastewater  treatment  works  bundle.  The  DBO  contract  is  progressing  in  accordance  with 
programme and it is expected to deliver against plan. 

The  Gascorp  Limited  farm  based  anaerobic  digester  (AD)  at  Garforth  in  West  Yorkshire  is  continuing  to  operate  and 
optimise its bio-gas export to the gas grid. Following an insured site incident, the plant has operated on a single digester 
for a significant period of time. The repair to the  damaged digester is due to be completed in  2018 and it  is anticipated 
that the AD plant will be back to its fully optimised capacity within a reasonable period thereafter. 

Other 
Following the transfer of non-household customers from NWL to NWGB from 1 April 2017, the non-household results are 
included in ‘Other’ (see note 2) up to the date of NWGB’s disposal on 31 August 2017 (see note 29). 

Dividends 
The Directors do not recommend payment of a final ordinary dividend (2017: £nil).  Total dividends paid in the year ended 
31 March 2018 were £109.4 million (2017: £108.3 million). 

Accounting policies 
The  consolidated  financial  statements  have  been  prepared  in  accordance  with  International  Financial  Reporting 
Standards (IFRS) as adopted by the European Union as it applies to the financial statements of the Group for the  year 
ended 31 March 2018. 

Capital structure, liquidity and credit rating 
The majority of the Group’s financing activities are undertaken within the NWL group of companies given the significance 
of  its  operations  to  Group  activities.   In  September  2015,  the  European  Investment  Bank  (EIB)  approved  a  new  £250 
million loan facility.  An initial £150 million tranche was drawn in October 2015. The remaining £100 million tranche was 
drawn in June 2017 at a fixed rate of 1.881%, swapped to index-linked at a favourable real rate of 1.1025%. 

In  October  2017,  through  NWL’s  finance  subsidiary  Northumbrian  Water  Finance  plc  (NWF),  we  issued  £300  million 
Guaranteed  Eurobonds,  with  an  annual  coupon  of  2.375%,  maturing  October  2027.  NWL  guaranteed  the  issue  and 
received the issue proceeds by way of an inter-company loan. The proceeds were partially used to repay the £180m bond 
which matured in October 2017  

NWL  has  cash  resources  and  substantial  undrawn  committed  five  year  bank  facilities  (maturing  in  2019)  available  to 
maintain general liquidity.  The undrawn bank committed facilities amounted to £350.0 million at 31 March 2018.

STRATEGIC REPORT (continued) 

Capital structure, liquidity and credit rating (continued) 
Interest cover and gearing measures have remained better than target levels.  NWL maintains its strong investment grade 
credit  ratings  of  BBB+  (stable  outlook)  from  Standard  &  Poors  (S&P)  and  Baa1  (negative  outlook)  from  Moody’s.    The 
difference  in  outlook  reflects  Moody’s  view  on  the  Group  gearing  level,  while  recognising  the  strength  of  the  regulatory 
ring-fence for NWL. 

Treasury policies 
The Board sets high level objectives for the financing strategy of the Group which is determined within treasury policies 
set  by  the  Board.   The  treasury  function  carries  out  treasury  operations  on  behalf  of  all  Group  companies  and  its  main 
purposes are to assess the ongoing capital requirement, to maintain short term liquidity, ensuring access to medium term 
committed  back  up  facilities,  and  to  raise  funding,  taking  advantage  of  any  favourable  market  opportunities.   It  also 
invests  any  surplus  funds  the  Group  has  in  accordance  with  the  Group’s  treasury  policy.   On  occasion,  derivatives  are 
used as part of this process, but the Group’s policies prohibit their use for speculation. 

The detailed financing strategy and dividend policy at NWL is determined independently by the board of NWL. 

PRINCIPAL RISKS AND UNCERTAINTIES 

The Group requires all Group companies to identify and assess the impact of risks to their business using a standard risk 
model.  The Group’s view of acceptable risk is based on a balanced view of all of the risks in the operating environment 
and it aims to ensure an appropriate balance between risk aversion and opportunities. 

The Board sets the tone for risk management within the Group and determines the appropriate risk appetite.  It monitors 
the  management  of  fundamental  risks  and  approves  major  decisions  affecting  the  Group’s  risk  profile.    The  Board  is 
supported in this by the Audit, Risk and Assurance Committee (ARAC) from which it receives regular and detailed reports.  
At  NWL, the ELT reviews  the  approach to  risk management in  detail every  year and reviews  the significant  risks  every 
month.    Any  issues  are  reported  by  the  Chief  Executive  Officer  (CEO)  to  the  boards  of  NWL  and  NWG.    NWG’s  ELT 
implements policies on risk management and internal control. 

Apart from NWL, none of the Group trading companies have risks considered to be significant to the Group's short and 
long term value. 

The system of internal control incorporates risk management.  It encompasses a number of elements, including policies 
and procedures, business planning and budgeting and the maintenance of a risk management framework, that together 
facilitate an effective and efficient operation, enabling the Group to respond effectively to a variety of challenges. 

The  ARAC,  on  behalf  of  the  Board,  carried  out  a  robust  assessment  of  the  principal  risks  facing  the  Group,  including 
those that would threaten its business model, future performance, solvency or liquidity, taking account of both the highest 
rated risks on our Corporate Risk Register and the Strategic Risk Register identified by the Board sub-group.  The risks 
are not set out in order of priority. 

The principal business risks facing the Group are: 
 
 
 

loss of customer trust and confidence; 
inherent health and safety risk in NWL’s operational and construction workplaces; 
loss of supply to a large volume of customers due to failure of the NWL water systems, such as failure of a strategic 
water main or treatment works or contamination of a service reservoir; 

  environmental  pollution  incidents  due  to  failures  in  the  NWL  wastewater  network  giving  rise  to  potential  fines  and 

reputational damage; 
loss of key business systems due to a malicious attack or failure of cyber security; 

 
  breach of Data Protection Act, General Data Protection Regulation or Environmental Information Regulations; 
  unfavourable  changes to the  NWL Licence or regulatory  methodology that  may  adversely  impact on  the balance of 

risk and return or reduce investor confidence in the stability and predictability of the regulatory framework; 

impact of changes in tax legislation; 

  a change in government could introduce significant changes in policy, impacting upon NWL and the Group; 
 
  effects of climate change adversely impacting NWL’s water resources and the integrity of the assets; 
 
 

failure to deliver financial plans could impact on expected shareholder returns; and 
funding and liquidity risk (see note 22 to the financial statements). 

Risk  management  is  a  dynamic  process  reflecting  changes  in  the  external  environment  and  consequently  some  of  the 
principal risks have changed from those reported in the previous year.

PRINCIPAL RISKS AND UNCERTAINTIES (continued) 

STRATEGIC REPORT (continued) 

New risks 
As part of their  assessment of principal risks, and taking account of the findings of the Financial Reporting Council Lab 
report on Risk and Viability Reporting, the ARAC decided that the potential impact of climate change should be added to 
the principal risks. 

Increasing risks 
No  risks  are  deemed  to  have  increased  over  the  year,  but  uncertainty  in  the  financial  markets  during  the  UK’s 
negotiations to leave the EU means that funding risk remains at a heightened level. 

Reducing risks 
As part of their assessment of principal risks, the ARAC decided to remove increased competition as a principal risk. This 
reflected the Company’s assessment that the introduction of upstream competition does not pose a significant risk whilst 
the potential introduction of household competition has not progressed. 

The main risks arising from the Group’s financial instruments are liquidity risk and interest rate risk.  The Board reviews 
and agrees policies for managing each of these risks as summarised in note 22 to the financial statements.  All treasury 
activities are conducted in accordance with the treasury policies of the Group.

CORPORATE GOVERNANCE 

DIRECTORS’ REPORT 

Notwithstanding that the Group is privately owned and therefore not subject to the UK Corporate Governance Code (the 
Code), the Group maintains high standards of corporate governance and endeavours to comply with the main principles 
of the Code, wherever appropriate. 

The  NWL  board  has  particular  regard  to  the  principles  underpinning  the  Code,  as  required  by  NWL’s  Instrument  of 
Appointment (the Licence), with only some minor aspects of the Code not being adopted. NWL seeks to comply with both 
the  principles and  spirit of  the Code,  in  the context  of  a  private company  with  a  single  ultimate controlling  shareholder. 
NWL  also  has  in  place  a  further  bespoke  governance  code,  developed  after  discussions  with  Ofwat,  in  response  to 
Ofwat’s Board leadership, transparency and governance principles. 

Directors 
The Directors who served during the year and up to date of signing were as follows: 

A J Hunter 
H Mottram CBE 
L S Chan 
F R Frame 
H L Kam 
D N Macrae 
W C W Tong-Barnes 

Non-Executive Chairman 
Chief Executive Officer (CEO) 
Non-Executive Director 
Non-Executive Director 
Non-Executive Director 
Non-Executive Director 
Non-Executive Director 

Information about Directors’ remuneration is contained in note 5 to the financial statements. 

Board responsibilities and processes 
The Board sets the Group’s high level vision, values and strategy and ensures compliance with Group policies and legal 
and regulatory obligations. Within this framework, NWL operates as a standalone company and its strategy is determined 
by the NWL board. During the year, the only decisions referred up to the NWG Board were a number of contract and loan 
approvals and the re-appointment of certain Directors (in each case, the NWG  Board approved the recommendations of 
the NWL board). 

The  Group  has  adopted  terms  of  reference  which  set  out  the  matters  reserved  to  the  Board  for  approval  and  matters 
which  are,  or  can  be,  delegated  to  the  committees  and  management.  The  Group  has  also  adopted  financial  approval 
rules which set out the authorisation processes and financial limits to be applied to financial transactions within the Group. 
NWL has adopted its own appropriate guidelines. 

The Standing Committee, which is a sub-committee of the Board, can take decisions not delegated to specific committees 
between Board meetings. All Directors receive notice of Standing Committee meetings and may participate if they wish. 
Decisions taken by the Standing Committee are reported at the next Board meeting.  The NWG Board meets at least five 
times each year. 

Authorisation of Directors’ conflicts of interest 
Directors have a statutory duty, under s175 of the Companies Act 2006, to avoid a situation in which they have, or could 
have,  a  conflict  of  interest  with  the  Company’s  interests.  However,  there  is  no  breach  of  this  duty  if  the  Board  has 
authorised the matter in question. The Articles permit Directors (other than the Director having the interest in question) to 
authorise any situation giving rise to a known or potential conflict.  A register of the interests which have been authorised 
is maintained by the Company Secretary and is available at every Board meeting. 

Board balance and independence 
The composition of the Board is as follows: 

A J Hunter (Chairman), D N Macrae and L S Chan were appointed by CK Infrastructure Holdings Limited. H L Kam and 
W C W Tong-Barnes  were  appointed  by  CKH,  which  is  now  wholly  owned  by  CKHH,  and  F R Frame  by  Li Ka  Shing 
Foundation  Limited.  The  CEO,  H Mottram  was  appointed  on  the  recommendation  of  the  Nomination  Committee  of 
Northumbrian Water Group plc when it was independently listed. 

The Chairman and CEO have clearly defined roles and responsibilities. The Chairman leads the Board and creates the 
conditions  for  overall  Board  and  individual  Director  effectiveness,  both  inside  and  outside  the  boardroom.  The  CEO  is 
responsible for running the Group’s businesses on a day-to-day basis.

DIRECTORS’ REPORT (continued) 

Board balance and independence (continued) 
Whilst  not  members  of  the  NWG  Board,  M Fay,  Dr Lyster,  P Rew  and  M A B Nègre  (the  independent  non-executive 
directors of NWL) attend Board and Committee meetings of NWG and therefore have visibility over, and are welcome to 
make observations and suggestions regarding strategic considerations at NWG, with the exception of matters relating to 
NWGB. This ensures that the NWL board is aware of all developments at the NWG level and therefore has full knowledge 
of the environment in which it is operating and any risks the Group might face.  The NWG Board believes that this entirely 
transparent approach supports compliance with Ofwat’s holding company principles 

The  General  Counsel  and  Company  Secretary,  M Parker,  assists  the  Board  to  ensure  that  good  corporate  governance 
compliance is achieved. He is also Company Secretary of NWL and is Secretary to all NWG and NWL board committees. 

The Committees were restructured in 2017 so that NWL now has its own Audit and Remuneration Committees as well as 
Risk  &  Compliance  and  Assurance  Sub-committees  of  the  Audit  Committee.  NWG  has  an  Audit,  Risk  and  Assurance 
Committee (ARAC). 

Board committees 
During the year, the Board was assisted by the ARAC in performing its duties. The Board sets the terms of reference of 
the Committees and receives regular reports from their chairmen at Board meetings.   

Remuneration Committee 
The remuneration of NWL’s CEO is set by NWL’s Remuneration Committee, the members of which, during the year, were 
A J Hunter  (Chairman),  P Rew,  M Fay,  S Lyster  and  D N Macrae.  S Salter,  from  the  NWL  Executive  Leadership  Team, 
provides advice to the Committee from time to time. 

NWL complies with its obligations under s35A of the Water Act 2003 by disclosing in its financial statements each year a 
detailed  breakdown  of  remuneration  paid  to  the  executive  Directors  of  NWL  which  is  linked  to  NWL’s  standards  of 
performance.  For two of the  NWL Executive  Directors,  H Mottram and C I Johns,  NWL  pays  70%  of their remuneration 
and NWG pays the remaining 30%, which reflects the time spent on activities other than NWL. For F R Frame, NWL pays 
30%  of  his  remuneration  and  NWG  pays  the  remaining  70%.  No  additional  remuneration  is  paid  by  the  Group  or  its 
shareholders. 

The  work  of  the  NWL  Remuneration  Committee  comprises  the  adoption  of  principles  and  standards  in  relation  to 
executive remuneration and benefits, as well as agreeing individual remuneration packages. 

ARAC 
The Chairman of the ARAC is L S Chan. The other members are D N Macrae (or his alternate) and N D Herrington. 

During the year, and up to the date of approval of these financial statements, the ARAC assisted both executive and non-
executive Directors to discharge their individual and collective responsibilities. Its work included the following: 

 

 

 

 

reviewing  the  draft  financial  statements,  considering  reports  from  the  external  and  internal  auditors  setting  out  the 
audit  approach  and  plan,  significant  audit  risks  and  conclusions  on  the  Group’s  internal  controls  and  risk 
management; 
reviewing the appropriateness of accounting policies, significant accounting judgements and evidence supporting the 
going  concern  basis  for  the  accounts  and  recommending  approval  of  both  statutory  and  regulatory  accounts  to  the 
Board; 
confirming  the  objectivity  and  independence  of  the  external  auditor,  and  in  so  doing  reviewing  the  representations 
made in the audit report on these subjects; 
reviewing  and  monitoring  the  effectiveness  of  the  audit  process,  taking  into  consideration  relevant  UK  professional 
and regulatory requirements; 

  monitoring the effectiveness of the internal audit function; 
  approving the external auditor’s fees for both audit and non-audit services, by reference to the agreed policy; 
  approving the internal audit work programme for the year and reviewing progress against the programme; 
  approving  arrangements  for  monitoring  compliance  with  the  Company’s  procedures  designed  to  prevent  bribery, 
having  regard  to  the  Bribery  Act  2010  and  the  updated  code  of  conduct  ‘Our  Way  at  NWG’,  including  receiving 
reports on any whistleblowing allegations; and 
reviewing  the  risk  and  control  framework  and  reporting,  including  management  of  tax  compliance  matters  and 
approval of financial approval rules. 

 

The chairman has reported formally to the NWG Board following each meeting of the Committee and minutes have been 
circulated to the Board.

DIRECTORS’ REPORT (continued) 

ARAC (continued) 
The ARAC is fully cognisant of the need for NWG to manage risk in such a way that NWL is protected from risk elsewhere 
in the group. Its work also included the following: 

 

 

reviewing reports at each meeting on the top rated managed risks and priorities for assurance (being those risks with 
the  biggest reduction between the business (gross) and managed (net) risk scores), representing key control areas 
for the Company; 
reviewing  and  updating the dynamic risk management framework and corporate  risk register which  are based  on  a 
detailed bottom-up assessment of risk across the Group; 
reviewing the management of specific areas of risk in relation to health and safety and environmental compliance; 
reviewing cyber security and steps being taken to enhance security; 

 
 
  advising  the  Board on  risk appetite  and  exposure and reviewing  risk assessment  processes as well  as keeping  the 

effectiveness of the risk and internal control management systems under review; 

  monitoring compliance with covenants and treasury risks; and 
 

reviewing business continuity arrangements. 

The  Board  is  able  to  monitor  the  impact  of  environmental,  social  and  governance  matters  on  the  Group’s  business,  to 
assess the impact of significant risks on the business and to evaluate methods of managing these risks through reports it 
receives from its subsidiary boards and committees. 

Code of conduct 
The  Group  has  a  code  of  ethics,  ‘Our  Code  of  Conduct’,  covering  Group  companies’  relationships  with  customers, 
employees, suppliers, local communities, shareholders, other investors and regulators. 

Governance Code 
In  March  2014,  following  discussions  with  Ofwat,  the  NWL  board  put  in  place  a  bespoke  Governance  Code  (the  NWL 
Code), which is available on the NWL website. 

Ofwat’s Holding Company Principles 
The  Company  has  reviewed  its  compliance  with  the  document  published  by  Ofwat  in  April  2014:  “Board  leadership, 
transparency and governance – holding company principles”. The principles set out by Ofwat are addressed below (the 
numbering follows that of the principles): 

1.1  As stated in the Strategic Report, at the balance sheet date, NWG is the holding company of NWL.  CKHH is the 

ultimate parent undertaking and controlling party of NWG and, therefore, NWL. 

1.2  NWG discloses detail of its debt structure and how this compares with the Group’s policies. It also clearly defines 
who is the ultimate parent  undertaking and controlling party (see 1.1 above) and gives full transparency as to the 
level of shareholder loan notes within the corporate structure. 

1.3  This report (and NWL’s Directors’ Report) disclose that some of the Directors of each company were appointed by 
shareholder companies. Directors may also, from time to time, have roles in and/or hold shares or other interests in 
the shareholder companies and/or other companies within the CKHH group. 

1.4  Decisions  regarding  certain  large  contract  awards,  capital  projects,  substantial  funding  arrangements  and  the  re-
appointment  of  directors  are  referred  to  the  NWG  Board.  During  the  year,  the  NWG  Board  has  endorsed  all  the 
recommendations of the NWL board. 

1.5  NWG’s governance arrangements are set out clearly in the Strategic Report and the Directors’ Report.  

2.1, 2.2, 2.3, 2.4 and 3.1 

The  Directors  of  NWG  are  all  also  Directors  of  NWL  and  NWL’s  independent  non-executive  directors  attend  all 
NWG’s  Board  and  Committee  meetings,  ensuring  full  transparency  between  the  two  companies.  The  executive 
management  teams  of  the  two  companies  are  the  same. The  NWG  Directors  are  therefore  fully  aware  of  NWL’s 
obligations,  under  statute,  under  the  Licence  (and  under  the  Condition  P  undertaking  required  by  the  Licence). 
NWL’s need to make strategic and sustainable decisions (in its own interests and those of its customers) is seen as 
fundamental to the Group’s strategy and is vigorously supported. Therefore, the flow of information between the two 
Boards  is  effective  and  relevant  information  regarding  the  wider  CKHH  group  is  freely  shared.  NWL  is  given  the 
opportunity to take advantage of business synergies and opportunities available within the CKHH group, but always 
makes its own business decisions in order to achieve the most favourable terms available. 

13 

 
 
 
 
 
 
 
 
 
 
 
 
DIRECTORS’ REPORT (continued) 

Ofwat’s Holding Company Principles (continued) 

Within this supportive environment, NWL’s board operates autonomously and each NWL director understands his 
or her individual responsibility to act in the best interests of NWL.  This enables NWL’s Board to make sustainable, 
long-term decisions which take full account of the long term nature of the water sector.  

OTHER DISCLOSURES 

Results, dividends, future developments and research and development 
Please refer to the Strategic Report. 

Political 
NWG  does  not  support  any  political  party  and  does  not,  directly  or  through  any  subsidiary,  make  what  are  commonly 
regarded as donations to  any political  party  or other political organisation.   However,  the  wide definition  of donations in 
the Political Parties, Elections and Referendums Act 2000 covers activities which form part of the necessary relationship 
between the Group and political parties and political organisations.  These activities include attending party conferences, 
as  these  provide  the  best  opportunity  to  meet  a  range  of  stakeholders,  both  national  and  local,  to  explain  the  Group’s 
activities, as well as local meetings with MPs, MEPs and their agents.  During the year, no external costs were associated 
with these activities, however, Company representatives attended the party conferences of the Labour and Conservative 
parties.  In addition, Group representatives also attended the party conferences of the Labour and Conservative parties. 

Financial instruments and treasury policies 
As described in treasury policies section of the Strategic Report. 

Employment policies 
The  Group’s  policies  in  respect  of  the  employment  for  disabled  persons  and  employee  involvement  are  set  out  in  the 
performance section of the Strategic Report. 

Indemnification of Directors  
NWG had in place Directors' and officers' insurance for the year.  On 21 March 2017, the Company entered into a deed of 
indemnity to grant the Directors of NWGL and its subsidiaries further protection against liability to third parties, subject to 
the conditions set out in the Companies Act 2006, and this remains in place. 

Directors’ declaration 
As required under s418 of the Companies Act 2006, so far as each current Director is aware, there is no relevant audit 
information of which the Company’s auditor is unaware and each Director has taken all the steps that he or she ought to 
have taken as a Director in order to make himself or herself aware of any relevant audit information and to establish that 
the Company’s auditor is aware of that information. 

Auditor 
Pursuant to s487  of the Companies Act  2006, Deloitte LLP is deemed to be re-appointed  as the Company’s auditor for 
the ensuing year. 

Financial statements preparation and going concern 
The Group has sufficient funding and facilities in place to meet its requirements for the foreseeable future.  The Directors 
believe that the Group is well placed to manage its business risks successfully and, accordingly, they continue to adopt 
the going concern basis in preparing the annual report and Group financial statements. 

In arriving at their decision, the Directors have taken into account: 
  NWL’s Instrument of Appointment which is in place on a rolling 25 year basis; 
 

the  certainty  on  wholesale  and  household  retail  price  controls  to  March  2020  provided  by  the  2014  Final 
Determination by Ofwat, following its acceptance by the Board; 

  NWL’s draft business plan for the next price control period from 2020-25; 
 

the  Board’s  view on NWL’s financial resilience for the seven years to March 2025 to assess the viability of NWL to 
align with the business planning process for the regulatory price review period to March 2025; 
the  financial  strength  of  the  Group  at  the  balance  sheet  date  and  performance  for  the  year  ended  31  March  2018, 
which is in line with expectations and reviewed at each Board meeting, most recently in April 2018; 
the  key  financial  ratios  over  the  next  12  month  planning  horizon,  as  reflected  in  strong  investment  grade  credit 
ratings; 
the fact that NWL has in place £350.0 million of five year committed bank facilities as back up liquidity (maturing  in 
2019), which was undrawn at 31 March 2018; 
the water and wastewater contracts are expected to be profitable over the term of their respective contracts; and 
the Group’s formal risk and governance arrangements which are monitored by the ARAC and Board.

DIRECTORS’ REPORT (continued) 

Fair, balanced and understandable 
The  Directors  consider  that  the  annual  report  and  financial  statements,  taken  as  a  whole,  is  fair,  balanced  and 
understandable and provides the information necessary for stakeholders to assess the company’s performance, business 
model  and  strategy.    In  reaching  this  conclusion,  the  Board  has  taken  advice  from  the  Audit  Committee  which  has 
considered  the  process  by  which  the  report  and  financial  statements  has  been  produced  as  well  as  reviewing  and 
commenting on the report. 

Directors’ responsibilities statement 
The Directors are responsible for preparing the annual report and the financial statements in accordance with applicable 
law and regulations. 

Company law requires the Directors to prepare financial statements for each financial year. Under that law the Directors 
have  elected  to  prepare  the  Group  financial  statements  in  accordance  with  International  Financial  Reporting  Standards 
(IFRS)  as  adopted  by  the  European  Union  and  the  parent  company  financial  statements  in  accordance  with  United 
Kingdom Generally Accepted Accounting Practice (United Kingdom Accounting Standards and applicable law), including 
FRS 101 “Reduced Disclosure Framework”. Under company law the Directors must not approve the financial statements 
unless they are satisfied that they give a true and fair view of the state of affairs of the company and of the profit or loss of 
the company for that period.  

select suitable accounting policies and then apply them consistently; 

In preparing the parent company financial statements, the Directors are required to: 
 
  make judgements and accounting estimates that are reasonable and prudent; 
 

state whether applicable UK Accounting Standards have been followed, subject to any material departures disclosed 
and explained in the financial statements; and 

  prepare the financial statements on the going concern basis unless it is inappropriate to presume that the Company 

will continue in business. 

In preparing the Group financial statements, International Accounting Standard 1 requires that Directors: 
  properly select and apply accounting policies; 
  present  information,  including  accounting  policies,  in  a  manner  that  provides  relevant,  reliable,  comparable  and 

understandable information;  

  provide additional disclosures when compliance with the specific requirements in IFRS are insufficient to enable users 
to understand the impact of particular transactions, other events and conditions on the entity’s financial position and 
financial performance; and 

  make an assessment of the Company’s ability to continue as a going concern. 

The  Directors  are  responsible  for  keeping  adequate  accounting  records  that  are  sufficient  to  show  and  explain  the 
Company’s  transactions  and  disclose  with  reasonable  accuracy  at  any  time  the  financial  position  of  the  Company  and 
enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for 
safeguarding the assets of 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 
Company’s  website.  Legislation  in  the  United  Kingdom  governing  the  preparation  and  dissemination  of  financial 
statements may differ from legislation in other jurisdictions.

INDEPENDENT AUDITOR’S REPORT TO THE MEMBERS OF NORTHUMBRIAN WATER GROUP 
LIMITED 

Opinion 
In our opinion: 
 

the  financial  statements  of  Northumbrian  Water  Group  Limited  (the  ‘parent  Company’)  and  its  subsidiaries  (the 
‘Group’) give a true and fair view of the state of the Group’s and of the parent Company’s affairs as at 31 March 2018 
and of the Group’s profit for the year then ended; 
the  Group  financial  statements  have  been  properly  prepared  in  accordance  with  International  Financial  Reporting 
Standards (IFRSs) as adopted by the European Union; 
the parent Company financial statements have been properly prepared in accordance with United Kingdom Generally 
Accepted Accounting Practice, including Financial Reporting Standard 101 “Reduced Disclosure Framework; and 
the financial statements have been prepared in accordance with the requirements of the Companies Act 2006. 

 

 

 

We have audited the financial statements which comprise: 
 
 
 
 
 
 
 

the consolidated income statement; 
the consolidated statement of comprehensive income; 
the consolidated and parent Company statements of changes in equity; 
the consolidated and parent Company balance sheets; 
the consolidated cash flow statement; 
the related consolidated notes 1 to 31; and 
the related parent Company notes 1 to 12. 

The financial reporting framework that has been applied in the preparation of the Group financial statements is applicable 
law  and  IFRSs  as  adopted  by  the  European  Union.  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, 
including 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 the parent Company in accordance with the ethical requirements that are relevant 
to  our  audit  of  the  financial  statements  in  the  UK,  including  the  Financial  Reporting  Council’s  (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. 

Summary of our audit approach 

Key audit matters 
for NWL 

The key audit matters that we identified for NWL in the current year were: 
  Classification of capital expenditure and operating expenditure; 
  Provision for bad and doubtful debts; 
  Revenue recognition (valuation of unbilled revenue accrual); and 
  Revenue recognition (adjustments to industry data from Market Operator Services 

Limited (MOSL)). 

Materiality 

Scoping 

The materiality that we used for the Group financial statements was £10.55 million which was 
determined on the basis of 5% of Group profit before tax.  

We performed audit work on all trading subsidiaries of the Group which represents 98.9% of the 
Group’s total assets (before consolidation adjustments), 99.8% of the Group’s revenue and 
96.8% of the Group’s profit before tax. 

Conclusions relating to going concern 
We are required by ISAs (UK) to report in respect of the following matters where: 
 

 

the  Directors’  use  of  the  going  concern  basis  of  accounting  in  preparation  of  the  financial  statements  is  not 
appropriate; or  
the  Directors  have  not  disclosed  in  the  financial  statements  any  identified  material  uncertainties  that  may  cast 
significant doubt about  the Group’s  or the parent Company’s ability to continue to adopt the going concern basis of 
accounting  for  a  period  of  at  least  twelve  months  from  the  date  when  the  financial  statements  are  authorised  for 
issue. 

We have nothing to report in respect of these matters.

INDEPENDENT AUDITOR’S REPORT TO THE MEMBERS OF NORTHUMBRIAN WATER GROUP 
LIMITED (continued) 

Key audit matters 
Key  audit  matters  are  those  matters  that,  in  our  professional  judgement,  were  of  most  significance  in  our  audit  of  the 
financial  statements  of  the  current  period  and  include  the  most  significant  assessed  risks  of  material  misstatement 
(whether or not due to fraud) that we identified. These matters included those which had the greatest effect on: the overall 
audit strategy, the allocation of resources in the audit; and directing the efforts of the engagement team. 

These  matters  were  addressed  in  the  context  of  our  audit  of  the  financial  statements  as  a  whole,  and  in  forming  our 
opinion thereon, and we do not provide a separate opinion on these matters. 

Classification of capital expenditure and operating expenditure (NWL) 

Key audit matter 
description 

The water industry is capital intensive and pipeline assets require regular maintenance and 
upgrades. There is an inherent risk in the industry that costs included in property, plant and 
equipment are not capital in nature and/or are not in line with the capitalisation criteria of IAS 16. 
NWL’s capital expenditure for the year ended 31 March 2018 was £256 million, together with 
significant spend on maintenance costs. 

How the scope of 
our audit 
responded to the 
key audit matter 

The classification of expenditure on capital assets also includes the allocation of certain 
overhead costs to property, plant and equipment reflecting the use of the NWL’S own teams and 
resources to complete capital work which requires the application of judgement. NWL’s 
capitalised labour costs were £37 million for the year ended 31 March 2018 (2017: £36 million).  

Further details are included in note 11 to the financial statements. 

  We evaluated the design and implementation of management’s key controls over the 

processing of accounting entries associated with capital and operating expenditure; 

  We have reviewed the appropriateness of the NWL’s capitalisation policies and its 

approach to determining which costs should be capitalised and which expensed; 
  We compared the actual capitalised expenditure incurred in the period with regulatory 
targets and made enquiries of management to understand any under/over spend; 
  We performed substantive testing on both capitalised and expensed amounts to assess 

whether these are classified in accordance with NWL’s policies and IAS 16; 
  We challenged management’s assumptions by comparing amounts capitalised by 

department in the current and prior years and we understood the reasons behind levels 
of capitalisation; and 

  We tested a sample of capitalised overheads by agreeing to timesheets and project 

plans to assess whether capitalisation was appropriate. 

Key observations 

The results of our procedures were satisfactory. We concluded that the valuation and 
classification of capital expenditure and operating expenditure are appropriately stated. 

Provision for bad and doubtful debts (NWL) 

Key audit matter 
description 

The value of the bad debt provision is calculated by applying a range of percentages to debt of 
different ages with higher percentages applied to different categories of debt depending on an 
assessment of the level of risk of default. There is a significant customer base, and regulations 
do not allow NWL to interrupt water supply to domestic customers. The valuation of the bad debt 
provision is sensitive to the specific percentages applied which are judgemental. 

At 31 March 2018 NWL’s gross debtors balance was £149 million (2017: £158 million) and the 
bad debt provision was £80 million (2017: £85 million). 

Further details are included note 14 to the financial statements.

INDEPENDENT AUDITOR’S REPORT TO THE MEMBERS OF NORTHUMBRIAN WATER GROUP 
LIMITED (continued) 

How the scope of 
our audit 
responded to the 
key audit matter 

  We evaluated the design and implementation of management’s key controls over the 

calculation of the bad debt provision; 

  We compared the assumptions made by management in calculating the provision to 

evidence provided from historical collection data; 

  We tested the accuracy and completeness of the aged debtor balance and the ageing 

categories applied; 

  We assessed the reasonableness of any judgements made in respect of likely future 

events through discussion of any known events with management and assessment of 
associated provision; 

  We tested a sample of credit notes raised to determine whether any were as a result of 

an event known but not appropriately provided for; 

  We performed sensitivity analysis on the provision to assess the impact of changes in 

the cash collection rate; and  

  We reviewed the receivables ageing report to assess whether overdue debtors are 

appropriately provided for. 

Key observations 

The results of our procedures were satisfactory. We have concluded that management’s 
judgements are appropriate and that the provision for bad and doubtful debts was appropriately 
stated. 

Revenue recognition (valuation of unbilled revenue accrual) (NWL) 

Key audit matter 
description 

The nature and scale of NWL’s business is such that it is not possible to read all water meters at 
year end. An estimate is therefore made of the unbilled revenue at the year end. At 31 March 
2018 this measured income accrual was £66 million (2017: £49 million).  

How the scope of 
our audit 
responded to the 
key audit matter 

Management estimates the amount of water and sewerage services that have been supplied to 
customers and not billed at year end, based on historic water consumption and default 
consumption rates. The revenue attributable to this unbilled revenue at year end is accrued. The 
accrual is both material and judgemental and is therefore considered to be a key audit matter.  

Further details are included within note 1b to the NWL financial statements. 

•  We evaluated the design and implementation of management’s key controls over the 

unbilled revenue accrual; 

•  We tested the operating effectiveness of controls over the revenue process to assess 

the integrity of reported turnover;  

•  We performed substantive testing of the accrued revenue calculation and made an 
assessment of the appropriateness of accounting estimates made by management; 
•  We reviewed the accrued revenue balance for indications of recoverability risk by tracing 

a sample to subsequent bill and cash payment; and  

•  We considered historic accuracy by performing retrospective testing on the March 2017 

balance. 

Key observations  The results of our procedures were satisfactory. We concluded that the valuation of unbilled 

revenue accrual is appropriate and concurred with management on judgements adopted.

INDEPENDENT AUDITOR’S REPORT TO THE MEMBERS OF NORTHUMBRIAN WATER GROUP 
LIMITED (continued) 

Revenue recognition (adjustments to industry data from MOSL) (NWL) 

Key audit matter 
description 

Following the opening of the non-household market to competition in England from 1 April 2017, 
NWL receives retail market data on which invoices to the retailers are based. There are a number 
of manual adjustments to be made for errors identified in these industry data feeds which are 
regularly corrected over time. 

Management therefore estimates the amount of water that has been supplied to retail customers 
and compares this to the data they are receiving, based on historic water consumption and default 
consumption rates. The value of these adjustments is currently circa. £3 million. 

The revenue recognised is material, and the adjustments made highly judgemental. Management 
have developed new controls and processes to deal with this new revenue input, and this is 
therefore considered to be a key audit matter.  

Further details are included in note 1j to the financial statements. 

How the scope 
of our audit 
responded to the 
key audit matter 

•  We evaluated the design and implementation of management’s key controls over the 

adjustments to the industry data from MOSL; 

•  We generated an independent expectation of the retail revenue for the year; 
•  We have performed substantive testing on a sample of the retail revenue recognised and 

made an assessment of the appropriateness of accounting estimates made by 
management; and 

•  We audited and understood significant adjustments to the data received externally, and 

assessed supporting evidence available from MOSL. 

Key 
observations 

The results of our procedures were satisfactory. We concluded that the adjustments made to 
industry data are appropriate and we concurred with management on judgements adopted. 

Our application of materiality 
We  define  materiality  as  the  magnitude  of  misstatement  in  the  financial  statements  that  makes  it  probable  that  the 
economic decisions of a reasonably knowledgeable person would be changed or influenced. We use materiality both in 
planning the scope of our audit work and in evaluating the results of our work. 

Based on our professional judgement, we determined materiality for the financial statements as a whole as follows: 

Group 
 financial statements 

Parent Company financial statements 

Materiality 

£10.55 million 

£10.44 million 

Basis for 
determining 
materiality 

Rationale for 
the 
benchmark 
applied 

5% of profit before tax 

Parent Company materiality equates to 1% of equity, due to 
the cap that was applied of £10.44 million, on the basis that 
the Company represents 100% of Group net assets 

The shareholders are interested in the 
profitability of the Group and as such 
monitors the business through how 
profitable the business is in order to 
maximise their returns. Therefore, 
profit before tax was determined to be 
most appropriate, being the stake they 
hold in the business. 

Given the parent Company is a holding company, equity 
was determined to be the most appropriate method of 
determining materiality.

INDEPENDENT AUDITOR’S REPORT TO THE MEMBERS OF NORTHUMBRIAN WATER GROUP 
LIMITED (continued) 

We agreed with the Audit Committee that we would report to the Committee all audit differences in excess of £0.2 million 
for  the  Group  and  £0.2  million  for  the  parent  Company,  as  well  as  differences  below  that  threshold  that,  in  our  view, 
warranted reporting on qualitative grounds. We also report to the Audit Committee on disclosure matters that we identified 
when assessing the overall presentation of the financial statements. 

An overview of the scope of our audit 
Our  Group  audit  was  scoped  by  obtaining  an  understanding  of  the  Group  and  its  environment,  including  group-wide 
controls, and assessing the risks of material misstatement at the Group level. We also conduct the statutory audit of all of 
the trading subsidiaries which represent 98.9% of the Group’s total assets (before consolidation adjustments), 99.8% of 
the Group’s revenue and 96.8% of the Group’s profit before tax. 

Our  audit  work  on  these  entities  was  conducted  at  levels  of  materiality  applicable  to  each  individual  entity  which  were 
lower than Group materiality and is capped at £10.44 million.  

At  the  parent  entity  level  we  also  tested  the  consolidation  process  and  carried  out  analytical  procedures  to  confirm  our 
conclusion  that  there  were  no  significant  risks  of  material  misstatement  of  the  aggregated  financial  information  of  the 
entities not subject to audit. 

Other information 
The Directors are responsible for the other information. The other information comprises the information included in the 
annual report, other than the financial statements and our auditor’s report thereon. 

Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly 
stated in our report, we do not express any form of assurance conclusion thereon. 

In connection with our audit of the financial statements, 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 audit or otherwise appears to be materially misstated. 

If  we  identify  such  material  inconsistencies  or  apparent  material  misstatements,  we  are  required  to  determine  whether 
there is a material misstatement in the financial statements or a material misstatement of the other information. If, based 
on  the  work  we  have  performed,  we  conclude  that  there  is  a  material  misstatement  of  this  other  information,  we  are 
required to report that fact. 

We have nothing to report in respect of these matters. 

Responsibilities of Directors 
As explained more fully in the Directors’ responsibilities statement, 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’s and the 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.

INDEPENDENT AUDITOR’S REPORT TO THE MEMBERS OF NORTHUMBRIAN WATER GROUP 
LIMITED (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. 

A  further  description  of  our  responsibilities  for  the  audit  of  the  financial  statements  is  located  on  the  FRC’s  website  at: 
www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report. 

Report on other legal and regulatory requirements 

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 the Directors’ Report have been prepared in accordance with applicable legal requirements. 

 

In the light of the knowledge and understanding of the Group and or the parent Company and their environment obtained 
in  the  course  of  the  audit,  we  have  not  identified  any  material  misstatements  in  the  Strategic  Report  or  the  Directors’ 
Report. 

Matters on which we are required to report by exception 
Adequacy of explanations received and accounting records 
Under the Companies Act 2006 we are required to report to you if, in our opinion: 
  we have not received all the information and explanations we require for our audit; or 
  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. 

 

We have nothing to report in respect of these matters. 

Directors’ remuneration 
Under  the  Companies  Act  2006  we  are  also  required  to  report  if  in  our  opinion  certain  disclosures  of  Directors’ 
remuneration have not been made. 

We have nothing to report in respect of these matters. 

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  ‘other  reserve’  represents  the  Company’s  reorganisation  of  its  ordinary  share  capital  on  8  March  2013,  which  the 
Directors consider to be distributable. 

The cash flow hedge reserve arises from the cumulative amount of gains or losses on hedging instruments taken directly 
to equity under the hedge accounting provisions of IAS 39. 

The  currency  translation  reserve  arises  from  exchange  differences  on  translation  of  the  net  assets  of  Group’s  foreign 
subsidiaries.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 
For the year ended 31 March 2018 

1. ACCOUNTING POLICIES 

(a) Statement of compliance 
The consolidated financial statements have been prepared in accordance with IFRS as adopted by the European Union 
as  it  applies  to  the  financial  statements  of  the  Group  for  the  year  ended  31  March  2018  and  in  accordance  with  the 
Companies Act 2006. 

The  financial  statements  have  been  prepared  on  a  going  concern  basis  taking  into  account  the  principal  risks  and 
uncertainties  disclosed  in  the  Directors’  Report,  which  assumes  that  the  Group  will  have  adequate  funding  to  meet  its 
liabilities  as  they  fall  due  in  the  foreseeable  future.    As  at  31  March  2018,  the  Group  had  net  current  assets  of  £34.8 
million  (2017:  net  current  liabilities  of  £182.3  million)  and  net  liabilities  of  £639.4  million  (2017:    £659.7  million).    The 
Directors have reviewed cash flow requirements, including reasonably possible changes in trading performance, and are 
confident  that  they  will  be  able  to  meet  these  from  funds  available  and  existing  financing  facilities.    Accordingly,  the 
Directors believe  it  is appropriate to  prepare  the financial statements on  a going  concern basis.   Further  details can  be 
found in the ‘Financial statements preparation and going concern’ section in the Directors’ Report. 

The Directors consider the following accounting policies to be relevant in relation to the Group’s financial statements.  The 
financial statements of the Group for the year ended 31 March 2018 were authorised for issue by the Board of Directors 
on 17 July 2018 and the balance sheet was signed on the Board’s behalf by H Mottram (CEO). 

The Group has adopted the following standards, amendments to standards and interpretations during the year: 

 
 
 

IAS 12 - Income taxes 
IAS 7 - Statement on cash flows 
Improvements to IFRSs (2014-2016); IFRS 12 

The adoption of the standards and interpretations listed above does not have a material impact on the Group. 

NWG is a private company, limited by shares and is registered, incorporated and domiciled in England and Wales. 

The Group financial statements are presented in sterling and all values are rounded to the nearest one hundred thousand 
pounds (£0.1 million) except where otherwise indicated. 

(b) Basis of consolidation 
The  consolidated  financial  statements  have  been  prepared  under  the  historical  cost  convention,  except  where  adopted 
IFRS  require  an  alternative  treatment.    The  consolidated  financial  statements  include  the  Company  and  its  subsidiary 
undertakings.  The results of subsidiaries acquired during the period are included from the date of their acquisition.  The 
results of subsidiaries disposed of during the period are included to the date of their disposal.  Inter-segment revenue and 
profits are eliminated fully on consolidation.  In accordance with IFRS 10 Consolidated Financial Statements and IFRS 12 
Disclosure of Interests in Other Entities, the financial statements of two companies are consolidated as special purpose 
entities, with effect from 12 May 2004, the date of the transaction which utilised these entities.  

Where  necessary,  adjustments  are  made  to  bring  the  accounting  policies  used  under  relevant  local  GAAP  in  the 
individual financial statements of the Company, subsidiaries and jointly controlled entities into line with those used by the 
Group under IFRS. 

Non-controlling interests represent the portion of profit or loss and net assets in subsidiaries that is not held by the Group 
and is presented within equity in the consolidated balance sheet, separately from parent shareholders’ equity.

1. ACCOUNTING POLICIES (continued) 

(c) Associates and jointly controlled entities  
Investments  in  associates  and  jointly  controlled  entities  in  the  Group  financial  statements  are  accounted  for  using  the 
equity method of accounting where the Group exercises significant influence over the associate.  Significant influence is 
generally  presumed to exist where the Group’s effective ownership is 20%  or more.  The Group’s share of the post tax 
profits less losses of  associates and  jointly controlled  entities  is  included in the  consolidated  income statement and  the 
carrying value in the balance sheet comprises the Group’s share  of their net assets/liabilities less distributions received 
and any impairment losses.  Goodwill arising on the acquisition of associates and jointly controlled entities, representing 
the excess of the cost of investment compared to the Group’s share of net fair value of the associate’s identifiable assets, 
liabilities  and  contingent  liabilities,  is  included  in  the  carrying  amount  of  the  associate  and  is  not  amortised.    Where 
necessary,  adjustments  are  made  to  bring  the  accounting  policies  used  into  line  with  those  of  the  Group  to  take  into 
account fair values assigned at the date of acquisition and to reflect impairment losses where appropriate.  Adjustments 
are  also  made  to  the  Group’s  financial  statements  to  eliminate  the  Group’s  share  of  unrealised  gains  and  losses  on 
transactions between the Group and its jointly controlled entities and associates. 

(d) Goodwill 
Goodwill arising on the acquisition of subsidiary undertakings and businesses represents the excess of the fair value of 
the consideration given over the fair value of the identifiable assets and liabilities acquired.  Following initial recognition, 
goodwill is measured at cost less any accumulated impairment losses.  Prior to 1 April 2004, goodwill was amortised over 
its estimated useful life; such amortisation ceased on 31 March 2004.  Goodwill relating to acquisitions since 1 April 2004 
is not amortised.  Goodwill is reviewed for impairment annually or more frequently if events or changes in circumstances 
indicate  that  the  carrying  value  may  be  impaired.    For  the  purposes  of  impairment  testing,  goodwill  is  allocated  to  the 
related cash-generating units monitored by management.  Where the recoverable amount of the cash-generating unit is 
less than its carrying amount, including goodwill, an impairment loss is recognised in the income statement.  The carrying 
amount  of  goodwill  allocated  to  a  cash-generating  unit  is  taken  into  account  when  determining  the  gain  or  loss  on 
disposal of the unit, or of an operation within it. 

(e) Intangible assets other than goodwill 
Other intangible fixed assets represent the right to receive income under the operating agreement with the EA in respect 
of  the  Kielder  Water  transfer  scheme.    The  value  of  this  intangible  asset  has  been  assessed  with  reference  to  the  net 
monies raised in accordance with the Kielder securitisation on 12 May 2004.  The term of the operating agreement is in 
perpetuity and,  accordingly, no  amortisation  is provided.   The value  of  this  intangible  is assessed for impairment  on  an 
annual basis in accordance with IAS 36 ‘Impairment of Assets’. 

Expenditure on internally developed intangible assets, excluding development costs, is taken to the income statement in 
the period in which it is incurred.  Intangible assets acquired separately from a business are carried initially at cost.  An 
intangible  asset  acquired  as  part  of  a  business  combination  is  recognised  outside  goodwill  if  the  asset  is  separable  or 
arises  from  contractual  or  other  legal  rights  and  its  fair  value  can  be  measured  reliably.    Development  expenditure  is 
recognised  as  an  intangible  asset  only  after  its  technical  feasibility  and  commercial  viability  can  be  demonstrated,  the 
availability  of adequate  technical  and  financial resources and  an  intention  to complete the project  have been confirmed 
and the correlation between development costs and future revenues has been established. 

(f) Property, plant and equipment  
Property, plant and equipment and depreciation  
Property, plant and equipment, including assets in the course of construction, comprise infrastructure assets (being mains 
and sewers,  impounding  and  pumped raw  water  storage  reservoirs,  dams,  sludge  pipelines and  sea  outfalls) and  other 
assets (including properties, overground plant and equipment). 

Purchased  property,  plant  and  equipment  are  included  at  cost  less  accumulated  depreciation  and  any  provision  for 
impairment.  Cost comprises the aggregate amount incurred and the fair value of any other consideration given to acquire 
the asset and includes costs directly attributable to making the asset capable of operating as intended. 

Where assets are constructed by a developer and adopted by NWL at no cost to the company, the assets are recognised 
in  the  balance  sheet  at  their  fair  value  on  the  date  of  the  transfer  and  an  equivalent  value  is  recognised  in  deferred 
income, in accordance with IFRIC 18 Transfers of Assets from Customers.  The fair value is based on the average cost to 
the Company of constructing an equivalent asset. 

Freehold  land  is  not  depreciated.    Other  assets  are  depreciated  evenly  over  their  estimated  economic  lives,  which  are 
principally  as  follows:  freehold  buildings,  30-60  years;  operational  structures,  plant  and  machinery,  4-92  years; 
infrastructure assets 4-200 years (see next page); and fixtures, fittings, tools and equipment, 4-10 years.  

28 

 
 
 
 
 
 
 
 
 
 
 
1. ACCOUNTING POLICIES (continued) 

(f) Property, plant and equipment (continued) 
The carrying values of property, plant and equipment are reviewed for impairment if events or changes in circumstances 
indicate the carrying value may not be recoverable and are written down immediately to their recoverable amount.  Useful 
lives  and  residual  values  are  reviewed  annually  and,  where  adjustments  are  required,  these  are  made  prospectively.  
Assets in the course of construction are not depreciated until commissioned. 

Infrastructure assets 
In the regulated water services business, infrastructure assets comprise a network of systems being mains and sewers, 
reservoirs, dams and sea outfalls. 

Infrastructure  assets  were  measured  at  a  date  prior  to  transition  to  IFRS  (23  May  2003)  at  their  fair  value,  which  was 
adopted as deemed historical cost on transition to IFRS.  The assets and liabilities were measured at fair value as a result 
of the acquisition on 23 May 2003. 

Expenditure  on  infrastructure  assets  which  enhances  the  asset  base  is  treated  as  fixed  asset  additions  while 
maintenance expenditure which does not enhance the asset base is charged as an operating cost. 

Infrastructure assets are depreciated evenly to their estimated residual values over their estimated economic lives, which 
are principally as follows: 

Dams and impounding reservoirs 
Water mains 
Sea outfalls 
Sewers  
Dedicated pipelines 

150 years 
100 years 
60 years 
200 years 
4-20 years 

(g) Financial assets 
Financial  assets comprise loans to  third  parties recoverable  in more  than  one  year  and  include  cash  held  on long  term 
deposit as a guaranteed investment contract relating to the Kielder securitisation.  These assets are recognised at cost 
and  are  measured  annually  based  on  the  ability  of  the  borrower  to  repay.    Any  impairment  is  taken  to  the  income 
statement  in  the  period  in  which  it  arises.    Loans  and  receivables  are  measured  at  amortised  cost  using  the  effective 
interest  rate  method.    The  Group  assesses  at  each  balance  sheet  date  whether  a  financial  asset  or  group  of  financial 
assets is impaired. 

(h) Foreign currency transactions 
Transactions  in  foreign  currencies  are  initially  recorded  in  the  functional  currency  by  applying  the  spot  exchange  rate 
ruling at the date of the transaction.  Monetary assets and liabilities denominated in foreign currencies are re-translated at 
the functional currency rate of exchange ruling at the balance sheet date.  The functional and presentational currency of 
NWG  is  United  Kingdom  sterling  (£).    Assets  and  liabilities  of  subsidiaries  and  jointly  controlled  entities  in  foreign 
currencies  are  translated  into  sterling  at  rates  of  exchange  ruling  at  the  end  of  the  financial  period  and  the  results  of 
foreign subsidiaries are translated at the average rate of exchange for the period.  Differences on exchange arising from 
the  re-translation  of  the  opening  net  investment  in  subsidiary  companies  and  jointly  controlled  entities,  and  from  the 
translation of the results of those companies at average rate, are taken to equity.  All other foreign exchange differences 
are taken to the income statement in the period in which they arise. 

Unrealised gains and losses arising from changes in foreign currency exchange rates are not cash flows.  However, the 
effect of exchange rate changes on cash and cash equivalents held or due in a foreign currency is reported in the cash 
flow statement in order to reconcile cash and cash equivalents at the beginning and the end of the period.  This amount is 
presented separately from cash flows from operating, investing and financing activities, where material, and includes the 
differences, if any, had those cash flows been reported at end of period exchange rates. 

(i) Inventories  
Inventories  are  stated  at  the  lower  of  cost  and  net  realisable  value.    Cost  comprises  direct  materials  and,  where 
applicable, direct labour costs, as well as an element of overheads that have been incurred in bringing the inventories to 
their present locations and condition. 

29 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
1. ACCOUNTING POLICIES (continued) 

(j) Revenues  
Provision of services 
Revenue,  which excludes  value added tax,  represents  the fair  value  of the  income  receivable  in  the ordinary course of 
business for services provided.  Revenue is recognised to the extent that it is probable that the economic benefits will flow 
to the Group and the revenue can be reliably measured. 

Revenue  is not  recognised until the services have been  provided to the  customer.   Revenue  for services relates to  the 
period, excluding any amounts paid in advance.  Revenue for measured water and wastewater charges includes amounts 
billed plus an estimation of the amounts unbilled at the year end.  The accrual is estimated using a defined methodology 
based upon daily average water consumption, which is calculated based upon historical billing information. 

(k) Dividends 
Dividends payable and receivable are recognised when the shareholders’ right to receive the revenue is established. 

(l) Grants and contributions  
Grants  are  recognised  at  their  fair  value  where  there  is  reasonable  assurance  that  the  grant  will  be  received  and  all 
attaching conditions will be complied  with.  Revenue  grants are credited to the income statement in the period to  which 
they relate.  Capital grants and contributions relating to property, plant and equipment are treated as deferred income and 
amortised  to  the  income  statement  over  the  expected  useful  economic  lives  of  the  related  assets.    Deferred  income 
relating to assets adopted from customers, recognised in accordance with IFRIC 18, is amortised to the income statement 
over the expected useful economic lives of the related assets. 

(m) Hire purchase and leasing 
Where assets are financed by leasing arrangements which transfer substantially all the risks and rewards of ownership to 
the Group, the assets are treated as if they had been purchased at their fair value or, if lower, at the present value of the 
minimum  lease  payments.    Rentals  or  leasing  payments  are  treated  as  consisting  of  a  capital  element  and  finance 
charges,  the  capital  element  reducing  the  outstanding  liability  and  the  finance  charges  being  charged  to  the  income 
statement over the period of the leasing contract at a constant rate on the reducing outstanding liability. 

Rentals under operating leases (where the lessor retains a significant proportion of the risks and rewards of ownership) 
are expensed in the income statement on a straight line basis over the lease term. 

(n) Pensions and other post-employment benefits  
Defined benefit scheme 
The  cost  of  providing  benefits  under  the  defined  benefit  scheme  is  determined  using  the  projected  unit  credit  method, 
which  attributes  entitlement  to  benefits  to  the  current  period  (to  determine  current  service  cost)  and  to  the  current  and 
prior periods (to determine the present value of defined benefit obligation) and is based on actuarial advice.  Past service 
costs are recognised in the income statement on a straight line basis over the vesting period or immediately if the benefits 
have vested.  When a settlement (eliminating all obligations for benefits already accrued) or a curtailment (reducing future 
obligations as a result of a material reduction in the scheme membership or a reduction in future entitlement) occurs, the 
obligation  and  related  plan  assets  are  re-measured  using  current  actuarial  assumptions  and  the  resultant  gain  or  loss 
recognised  in  the  income  statement  during  the  period  in  which  the  settlement  or  curtailment  occurs.    Net  interest  is 
calculated by applying the discount rate to the net defined benefit asset or liability.   

The service cost is disclosed in employment costs and the net interest expense is disclosed within finance costs payable. 

Actuarial gains and losses on experience adjustments and changes in actuarial assumptions are recognised in full in the 
period in which they occur in the consolidated statement of comprehensive income. 

Defined contribution scheme 
The Group also operates defined contribution schemes.  Obligations for contributions to the scheme are recognised as an 
expense in the income statement in the period in which they arise. 

(o) Taxation 
Current tax 
Current tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered 
from,  or  paid  to,  the  taxation  authorities.    The  tax  rates  and  tax  laws  used  to  compute  the  amounts  are  those  that  are 
enacted or substantively enacted by the balance sheet date. 

30 

 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
1. ACCOUNTING POLICIES (continued) 

(o) Taxation (continued) 
Deferred tax 
Deferred  tax  is  provided  using  the  liability  method  on  temporary  differences  at  the  balance  sheet  date  between  the  tax 
bases of assets and liabilities and their carrying amounts for financial reporting purposes. 

Deferred tax liabilities are recognised for all taxable temporary differences except: 
  where the deferred tax liability arises from the initial recognition of goodwill or of 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 
in  respect  of  taxable  temporary  differences  associated  with  investments  in  subsidiaries,  associates  and  interests  in 
jointly  controlled  entities,  where  the  timing  of  the  reversal  of  the  temporary  differences  can  be  controlled  and  it  is 
probable that the temporary differences will not reverse in the foreseeable future. 

 

Deferred  tax  assets  are  recognised  for  all  deductible  temporary  differences,  carry  forward  of  unused  tax  credits  and 
unused  tax  losses,  to  the  extent  that  it  is  probable  that  taxable  profit  will  be  available  against  which  the  deductible 
temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilised except: 
  where  the  deferred  tax  asset relating  to the  deductible  temporary  difference  arises from the  initial recognition  of 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 
in respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in 
jointly controlled entities, deferred tax assets are recognised only to the extent that it is probable that the temporary 
differences  will  reverse  in  the  foreseeable  future  and  taxable  profit  will  be  available  against  which  the  temporary 
differences can be utilised. 

 

The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no 
longer  probable  that  sufficient  taxable  profit  will  be  available  to  allow  all  or  part  of  the  deferred  tax  asset  to  be  utilised.  
Unrecognised deferred tax assets are reassessed at each balance sheet date and are recognised to the extent that it has 
become probable that future taxable profit will allow the deferred tax asset to be recovered. 

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is 
realised or the liability is settled, based on tax rates (and tax laws) that have been enacted, or substantively enacted, at 
the balance sheet date. 

Deferred  tax  is  recognised  in  the  income  statement,  except  when  it  relates  to  items  that  are  recognised  in  other 
comprehensive  income  or  directly  in  equity,  in  which  case,  the  deferred  tax  is  also  recognised  in  other  comprehensive 
income or directly in equity respectively. 

Deferred tax assets and deferred tax liabilities are offset, if a legally enforceable right exists to set off current tax assets 
against current tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority. 

Value added tax 
Revenues, expenses and assets are recognised net of the amount of value added tax except: 
  where the value added tax incurred on a purchase of assets or services is not recoverable from the taxation authority, 
in  which  case  the  value  added  tax  is  recognised  as  part  of  the  cost  of  acquisition  of  the  asset  or  as  part  of  the 
expense item as applicable; and 
receivables and payables.  The net amount of value added tax recoverable from, or payable to, the taxation authority 
is included as part of receivables or payables in the balance sheet. 

 

(p) Derivative financial instruments 
The  Group  utilises  interest  and  inflation  rate  swaps,  gilt  locks  and  forward  exchange  contracts  as  derivative  financial 
instruments. 

A  derivative  instrument  is  considered  to  be  used  for  hedging  purposes  when  it  alters  the  risk  profile  of  an  underlying 
exposure  of  the  Group  in  line  with  the  Group’s  risk  management  policies.    Interest  rate  swap  agreements  are  used  to 
manage interest rate exposures.  Derivative financial instruments are stated at their fair value. 

Hedge  accounting  is  employed  in  respect  of  those  derivative  financial  instruments  fulfilling  the  requirements  for  hedge 
accounting as prescribed under IAS 39.  In summary, these criteria relate to initial designation and documentation of the 
hedge  relationship,  prospective  testing  of  the  relationship  to  demonstrate  the  expectation  that  the  hedge  will  be  highly 
effective throughout its life and subsequent retrospective testing of the hedge to verify effectiveness. 

31 

 
 
 
 
 
 
 
 
 
 
 
 
 
1. ACCOUNTING POLICIES (continued) 

(p) Derivative financial instruments (continued) 
Under IFRS 13, derivative financial instruments are measured at fair value, which is considered to be the price that would 
be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  in  an  orderly  transaction  reflecting  the  credit  risk  of  the 
counterparties in the principal (or most advantageous) market under market conditions as at the balance sheet date. 

The fair value  of forward  exchange contracts  is calculated  by reference  to  current  forward  exchange  rates for contracts 
with similar maturity profiles.  The fair value of interest rate swaps is determined by reference to market values for similar 
instruments. 

Hedging transactions undertaken by the Group are classified as either fair value hedges when they hedge the exposure 
to changes in the fair value of a recognised asset or liability; or cash flow hedges where they hedge exposure to variability 
in  currency  cash  flows  that  is  either  attributable  to  a  particular  risk  associated  with  a  recognised  asset  or  liability  or  a 
forecast transaction. 

In relation to fair value hedges, which meet the conditions for hedge accounting, any gain or loss from re-measuring the 
hedging instrument at fair value is recognised immediately in the income statement. 

In relation to cash flow hedges to hedge firm currency commitments which meet the conditions for hedge accounting, the 
portion of the gain or loss on the hedging instrument that is determined to be an effective hedge is recognised directly in 
the cash flow hedge reserve and the ineffective portion is recognised in the income statement. 

When the hedged firm commitment results in the recognition of a non-financial asset or a non-financial liability then, at the 
time the asset or  liability is recognised, the associated gains or  losses that had  previously  been recognised in the cash 
flow hedge reserve are included in the initial measurement of the acquisition cost or other carrying amount of the asset or 
liability.    For  all  other  cash  flow  hedges,  the  gains  or  losses  that  are  recognised  in  the  cash  flow  hedge  reserve  are 
transferred  to  the  income  statement  in  the  same  periods  in  which  the  hedged  firm  commitment  affects  the  income 
statement. 

For derivatives that do not qualify for hedge accounting, any gains or losses arising from changes in fair value are taken 
directly to the income statement. 

Hedge accounting is discontinued when the hedging instrument expires or is sold, terminated or exercised, or no longer 
qualifies for hedge accounting.  At that point in time, any cumulative gain or loss on the hedging instrument recognised in 
the  cash  flow  hedge  reserve  is  kept  in  the  cash  flow  hedge  reserve  until  the  forecast  transaction  occurs.    If  a  hedged 
transaction is no longer expected to occur, the net cumulative gain or loss recognised in the cash flow hedge reserve is 
transferred to the income statement. 

(q) Interest bearing loans and borrowings 
All  loans  and  borrowings  are  initially  stated  at  the  amount  of  the  net  proceeds,  being  fair  value  of  the  consideration 
received net of issue costs associated with the borrowing.  Finance costs (including issue costs) are taken to the income 
statement  over  the  term  of  the  debt  at  a  constant  rate  on  the  balance  sheet  carrying  amount.    The  carrying  amount  is 
increased  by  the  finance  charges  amortised  and  reduced  by  payments  made  in  respect  of  the  accounting  period.    The 
carrying  amount  of  index  linked  borrowings  increases  annually  in  line  with  the  relevant  RPI,  with  the  accretion  being 
charged to the income statement as finance costs payable.  Other borrowing costs are recognised as an expense when 
incurred. 

Loans  and  borrowings  acquired  at  acquisition  are  restated  to  fair  value.    The  adjustment  arising  on  acquisition  is 
amortised to the income statement on the basis of the maturity profile of each instrument.  Realised gains and losses that 
occur from the early termination of loans and borrowings are taken to the income statement in that period. 

Net  debt  is  the  sum  of  all  current  and  non-current  liabilities  less  cash  and  cash  equivalents,  short  term  cash  deposits, 
financial investments and loans receivable. 

(r) Borrowing costs 
Borrowing  costs are  generally expensed as incurred.   Borrowing costs that  are  directly  attributable  to the  acquisition  or 
construction of an asset that necessarily takes a substantial time to prepare for its intended use are capitalised while the 
asset is being constructed as part of the cost of that asset. 

Capitalisation  ceases  when  the  asset  is  substantially  ready  for  its  intended  use  or  sale.    If  active  development  is 
interrupted for an  extended period,  capitalisation  is suspended.   When construction occurs  piecemeal, and  use  of each 
part ceases upon substantial completion of that part, a weighted average cost of borrowings is used.

1. ACCOUNTING POLICIES (continued) 

(r) Borrowing costs (continued) 
The Group capitalises borrowing costs for all eligible assets when construction commenced on or after 1 April 2009 and 
continues to expense borrowing costs relating to construction projects that commenced prior to that date. 

(s) Loans and receivables 
Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an 
active  market,  do  not  qualify  as  trading  assets  and  have  not  been  designated  as  either  fair  value  through  the  income 
statement or available for sale.  Gains and losses are recognised in income when the investments are de-recognised or 
impaired, as well as through the amortisation process. 

(t) Cash and cash equivalents and short term cash deposits 
Cash and cash equivalents disclosed  in the balance sheet comprise cash at bank and in hand and short term deposits 
with  a  maturity  on  acquisition  of  three  months  or  less,  which  are  held  for  the  purpose  of  meeting  short  term  cash 
commitments rather than for investment or other purposes.  Cash equivalents are readily convertible to a known amount 
of cash and subject to an insignificant risk of changes in value. 

Short term  cash  deposits disclosed  in the  balance  sheet comprise cash  deposited  with a maturity of  greater than three 
months on acquisition, a fixed interest rate and which do not constitute cash equivalents under IAS 7 ‘Statement of Cash 
Flows’. 

For  the  purpose  of  the  consolidated  cash  flow  statement,  cash  and  cash  equivalents  are  as  defined  above,  net  of 
outstanding bank overdrafts. 

(u) Trade and other receivables 
Trade receivables are recognised and carried at original invoice amount less an allowance for any uncollectable amounts. 
Invoices for unmeasured water and wastewater charges are due on fixed dates; other receivables generally have 30 day 
payment  terms.   An  estimate  for doubtful debts is  made  when  collection  of  the full amount  is no  longer probable.   Bad 
debts are written off when identified.  Trade and other receivables do not carry any interest. 

(v) Fixed asset investments 
Investments are initially recorded at the fair value of the consideration given including the acquisition charges associated 
with the investment.  Subsequent to initial recognition, they are valued at original cost less any impairment. 

(w) Provisions 
Provisions are recognised when the Group has a present obligation (legal or constructive) as a result of a past event, it is 
probable  that  an  outflow  of  resources  will  be  required  and  a  reliable  estimate  can  be  made  of  the  amount  of  the 
obligation. 

(x) Impairment of assets 
The  Group assesses at each  reporting date  whether there  is  an  indication  that  an asset may  be  impaired.   If any such 
indication exists, or when annual impairment testing for an asset is required, the Group makes an estimate of the asset’s 
recoverable amount.  An asset’s recoverable amount is the higher of an asset’s or cash-generating unit’s fair value less 
costs  to  sell  and  its  value  in  use  and  is  determined  for  an  individual  asset,  unless  the  asset  does  not  generate  cash 
inflows  that  are  largely  independent  of  those  from  other  assets  or  groups  of  assets.   Where  the  carrying  amount  of  an 
asset exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount.  In 
assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate 
that  reflects  current  market  assessments  of  the  time  value  of  money  and  the  risks  specific  to  the  asset.    Impairment 
losses on continuing operations are recognised in the income statement in those expense categories consistent with the 
function of the impaired asset. 

An  assessment  is  made  at  each  reporting  date  as  to  whether  there  is  any  indication  that  previously  recognised 
impairment  losses  may  no  longer  exist  or  may  have  decreased.    If  such  indication  exists  the  recoverable  amount  is 
estimated.  A previously recognised impairment loss is reversed only if there has been a change in the estimates used to 
determine the asset’s recoverable amount since the last impairment loss was recognised.  If that is the case the carrying 
amount of the asset is increased to its recoverable amount.  That increased amount cannot exceed the carrying amount 
that  would  have  been  determined,  net  of  depreciation,  had  no  impairment  loss  been  recognised  for  the  asset  in  prior 
years.  Such reversal is recognised in the income statement unless the asset is carried at revalued amount, in which case 
the  reversal  is  treated  as  a  revaluation  increase.    After  such  a  reversal  the  depreciation  charge  is  adjusted  in  future 
periods to allocate the asset’s revised carrying amount, less any residual value, on a systematic basis over its remaining 
useful life.

1. ACCOUNTING POLICIES (continued) 

(y) De-recognition of financial assets and liabilities 
A financial asset or liability is generally de-recognised when the contract that gives rise to it is settled, sold, cancelled or 
expires. 

Where  an  existing  financial  liability  is  replaced  by  another  from  the  same  lender  on  substantially  different  terms,  or  the 
terms of an existing liability are substantially modified, such an exchange or modification is treated as a de-recognition of 
the  original  liability  and  the  recognition  of  a  new  liability,  such  that  the  difference  in  the  respective  carrying  amounts 
together with any costs or fees incurred are recognised in the income statement. 

(z) Accounting standards 
At  the  date  of  signing  of  these  financial  statements,  the  following  relevant  major  standards  were  in  issue  but  not  yet 
effective. The Directors anticipate that the Group will adopt these standards on their effective dates. There are no other 
standards or interpretations in issue but not yet adopted which the Directors anticipate will have a material impact on the 
Group. 

IFRS 9 – Financial Instruments 
This standard relates to the measurement and disclosure of financial instruments. The Group does not anticipate that the 
adoption of IFRS 9 will have a material impact on the financial statements in the period of initial application. 

IFRS 15 – Revenue from Contracts with Customers 
This standard relates to the recognition of revenue from customers. The Group  has assessed the impact of IFRS 15  in 
respect of the two material revenue streams in NWL, being revenue from the provision of water and wastewater services 
to customers and revenue received in respect of contributions to capital investment, particularly from developers. 

The  Group  does  not  anticipate  that  there  will  be  any  change  to  the  timing  of  recognition  of  revenue  for  water  and 
wastewater services upon the adoption of IFRS 15. 

In respect of contributions to capital investment, this revenue is currently recognised as deferred income in the balance 
sheet and amortised to the income statement over the useful life of the associated assets (see note 21). Under IFRS 15 
the revenue must be recognised in line with the satisfaction of the performance obligations to the customer. 

For contributions related to the connection of new properties to NWL’s networks, comprising infrastructure charges, new 
connection  charges  and  requisitioned  mains  and  sewers,  the  Group  considers  that  these  activities  form  a  combined 
performance obligation that is not distinct from the ongoing provision of water and wastewater services through the new 
connection. On this basis, it is anticipated that these contributions will continue to be recognised as deferred income and 
amortised to the income statement over the expected useful life of the connection. 

For other contributions to capital investment, most significantly mains and sewer diversions in NWL, the Group considers 
that the performance obligation is satisfied upon completion of the investment, which  will typically be the point at  which 
the associated asset is brought into use. On this basis, it is anticipated that these contributions will be recognised in full in 
the income statement upon satisfaction of the performance obligation. 

IFRS  15  will  be  applied retrospectively  with  the  cumulative  effect recognised at  the  date of  initial  application.   Deferred 
income  related  to  contributions  for  activities,  which  will  be  recognised  in  full  in  the  income  statement  in  future,  will  be 
transferred from deferred income to reserves, along with the associated deferred tax. The estimated cumulative impact on 
transition, 1 April 2018, is a credit to reserves of £70.9 million with an associated deferred tax impact of £12.0 million. 

IFRS 16 – Leases 
This  standard  sets  of  out  the  principles  for  the  recognition,  measurement,  presentation  and  disclosure  of  leases.  The 
primary  impact  will  be  to  reclassify  most  leases  currently  classified  as  operating  leases,  as  disclosed  in  note  19,  as 
finance leases. This will result in the recognition of a non-current asset and a broadly equivalent finance lease obligation 
on the balance sheet. 

Work is ongoing to ensure that all contractual arrangements falling within scope of the standard are correctly identified. 
The Group does not anticipate that the adoption of IFRS 16 will have a material impact on the reported profit in the period 
of initial application.

1. ACCOUNTING POLICIES (continued) 

(aa) Significant accounting judgements and key sources of estimation uncertainty 
In  the  process  of  applying  the  accounting  policies,  the  Group  is  required  to  make  certain  judgements,  estimates  and 
assumptions that it believes are reasonable based on the information available.  Actual results may have a significant risk 
of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year. 

The significant accounting judgements were: 
 

the estimation of income for measured water and sewerage services supplied but not billed at the end of the financial 
period.  Consumption  by  measured  domestic  customers  is  billed  in  arrears  on  quarterly  or  six-monthly  cycles. 
Revenue is estimated and accrued using a defined methodology based upon historical usage and the relevant tariff 
per  customer.  Consumption  by  non-household  properties  is  billed  to  the  relevant  retailer  under  the  terms  of  the 
Wholesale Contract and may be either in advance or in arrears. Revenue billed in arrears is estimated by reference to 
wholesale  market  settlement  reports,  adjusted  for  any  additional  information  obtained  after  a  settlement  report  has 
been run; 
the  estimation  of  uncertain  tax  provisions,  which  are  assessed  on  advice  from  independent  tax  advisers  and  the 
status of ongoing discussions with the relevant tax authorities; and 
the asset lives assigned to property, plant and equipment, details of which can be found in note 1(f). 

The significant accounting estimates were: 
 

those  assumptions  used  in  arriving  at  the  pension  asset/liability  under  IAS  19.    These  key  assumptions  and  their 
possible impact are disclosed in note 26, ‘Pensions and other post-retirement benefits’; 
the  bad  debt  provision,  which  is  calculated  by  applying  a  range  of  percentages  to  debt  of  different  ages.    These 
percentages also  vary between different categories of  debt.   Higher percentages are  applied  to  those  categories of 
debt which are considered to be of greater risk and also to debt of greater age.  The value of the bad debt provision is 
sensitive to the specific percentages applied.

2. SEGMENTAL ANALYSIS 

For  management  purposes,  the  Group  is  organised  into  business  units  according  to  the  nature  of  its  products  and 
services  and  has  three  reportable  operating  segments.   The  trading  of  the  business  is  principally  carried  out  within  the 
UK.  Profit is measured at profit on ordinary activities before interest. 

Northumbrian Water Limited (NWL) 
NWL is one of the ten regulated water and sewerage businesses in England and Wales.  NWL operates in the north east 
of England, where it trades as Northumbrian Water, and in the south east of England, where it trades as Essex & Suffolk 
Water.  NWL also has non-regulated activities closely related to its principal regulated activity. 

Water and wastewater contracts 
NWG owns a number of companies for specific water and wastewater contracts in Scotland, the Republic of Ireland and 
Gibraltar. NWG also controls a farm based anaerobic digestion plant in West Yorkshire, England. 

Other 
Central  unallocated  costs and  provisions are  included  in this segment.   NWGB, NWG’s  retailer following the transfer of 
non-household customers from NWL, is also included in this segment up to 31 August 2017 (see note 29). 

Transfer prices between business segments are set on an arm’s length basis in a manner similar to transactions with third 
parties.  Segment revenue, segment expense and segment result include transfers between business segments.  Those 
transfers are eliminated on consolidation.

Finance (No. 2) Act 2015 reduced the rate of UK corporation tax from 20% to 19% with effect from 1 April 2017.  Finance 
Act 2016 provides that this will be reduced to 17% with effect from 1 April 2020. Deferred tax has been provided wholly at 
17% as the impact of amounts that are expected to reverse at the higher rate is insignificant. 

Overseas tax relates to the Group's activity in the Republic of Ireland.  No overseas tax arises in respect of the Group's 
activity in Gibraltar due to the existence of brought forward losses. 

(b) Tax relating to items charged or credited outside the income statement 

Deferred tax:

The effective tax rate for the year ended 31 March 2018 was 19.7% (year ended 31 March 2017: -8.3%).  The increase of 
28.0% mainly reflects the absence of any further reductions in the UK corporation tax rate (29.4%), an increase in profit 
before  tax  (-1.0%),  an  increase  in  non-taxable  income  (-0.5%),  a  recovery  of  amounts  previously  paid  for  tax  losses 
following the withdrawal of a consortium relief claim (3.1%), offset by an increase in prior period charges (-3.0%).

8. TAXATION (continued) 

(e) Factors that may affect future tax charges 
The Group expects to continue to incur high levels of capital expenditure for the foreseeable future which, under current 
tax legislation, should result in claims for tax reliefs in excess of depreciation. 

New rules have been introduced by the UK Government (with retrospective effect from 1 April 2017) to implement Action 
4  of  the  OECD's  Base  Erosion  and  Profit  Shifting  (BEPS)  project.  The  rules  determine  the  amount  of  interest  that 
companies can deduct for UK corporation tax purposes. A proportion of the Group's interest payable in the current year is 
considered not to be immediately deductible for tax purposes and has increased the tax charge by £6.7 million.  However, 
the Group is of the opinion that amounts which have been disallowed will be reactivated under the BEPS legislation and 
become fully deductible over the next two years. As a result, a matching deferred tax asset has been recognised of £6.7 
million.

The  intangible  asset represents the right  in  perpetuity  to  receive income under  the  operating  agreement  with  the EA  in 
respect  of  the  Kielder  Water  transfer  scheme  and,  therefore,  the  Directors  consider  the  asset  has  an  indefinite  life.  
Accordingly,  future  cash  flows,  which  increase  in  line  with  inflation  and  have  been  assumed  at  2.56%,  have  been 
discounted at a rate of 3.6% in perpetuity to calculate a value in use.  This represents a long term nominal gilt yield and 
an assumed credit spread.  This calculation satisfied  the Group that the carrying value  at 31 March 2018 had not been 
impaired.  Furthermore, it is improbable that the discount rate would increase to such a level that the carrying value would 
be impaired.

(a)  Group strategy and funding risk 
The level of capital expenditure which the Group is obliged to incur is such that it cannot be wholly financed by internally 
generated sources.  As a result, the Group must rely upon raising additional finance on a regular basis, to be principally 
used to fund the long term assets required in its regulated business.  The Group’s strategy is to finance such investment 
by raising medium to long term debt, to provide a balance sheet match with long term assets and to fix a major proportion 
of interest rates.  In order to raise this finance efficiently, the Board’s aim is to retain strong investment grade credit rating 
at BBB+ stable (Standard & Poors) and Baa1 stable (Moody’s).  A reduction in the credit rating would likely restrict future 
sources  of  funding  and  increase  the  associated  cost  of  new  borrowing.    Also,  the  loss  of  EIB  as  a  source  of  low  cost 
funding, due to Brexit, would increase borrowing costs. 

(b)  Treasury operations 
The  main  purpose  of  the  Group’s  treasury  function  is  to  assess  the  Group’s  ongoing  capital  requirement  and  to  raise 
funding on a timely basis, taking advantage of any favourable market opportunities.  It also invests any surplus funds the 
Group  may  have,  based  upon  its  forecast  requirements  and  in  accordance  with  the  Group’s  treasury  policy.    On 
occasions, derivatives are used as part of this process but the Group’s policies prohibit their use for speculation. 

(c)  Risks arising from the Group’s financial instruments 
The main risks arising from the Group’s financial instruments are liquidity risk, interest rate risk and foreign currency risk.  
The Board reviews and agrees policies for managing each of these risks and they are summarised below.  All treasury 
activities are conducted in accordance with these policies. 

(d)  Liquidity risk 
As regards day to day liquidity, the Group’s policy is to have available committed bank borrowing facilities with a value of 
no less than £50.0 million and with a bank agreement availability period of no less than three months.  At 31 March 2018, 
the Group had £350.0 million (2017: £350.0 million) of undrawn committed bank facilities (maturing in 2019). 

(e)  Interest rate risk  
The Group finances its operations through a mixture of retained profits and bank borrowings.  It borrows at both fixed and 
variable rates of interest and, accordingly, uses interest rate swaps to generate the desired interest profile and to manage 
the Group’s exposure to interest rate fluctuations.  The Group’s policy is to keep a minimum 60% of its borrowings at fixed 
rates  of  interest.  At  31  March  2018,  69%  (2017:  70%)  of  the  Group’s  borrowings  were  at  fixed  rates  of  interest.  Index 
linked borrowings are treated as variable rate debt.  

(f)  Foreign currency risk 
The Group’s policy is that any foreign currency exposure in excess of £100k sterling equivalent of a transactional nature, 
or £3.0 million sterling equivalent of a translation nature, should be covered immediately on identification.  Any exposures 
are covered through the use of forward foreign exchange contracts.

22. FINANCIAL INSTRUMENTS (continued) 

(g)  Market price risk 
The Group’s exposure to market price risk principally comprises interest rate exposures.  The Group’s policy is to accept 
a degree of interest rate risk. The following table shows the impact on profit and equity of an increase in the variable cost 
of  borrowing.    The  range  is  considered  reasonable  based  on  the  forecast  variable  rates  of  borrowing  and  all  other 
elements being consistent for the next 12 months and highlights this is not material to the Group:

(h) Credit risk 
There are no significant concentrations of credit risk within the Group.  Management’s assessment of the maximum credit 
risk exposure relating to financial assets is represented by their carrying value as at the balance sheet date (see 22(o)).  
A  significant proportion  of the  trade  debtor balances are  with domestic  customers who  are unlikely  to  have a  published 
credit rating (see note 14). 

(i) Counterparty risk 
The treasury strategy, which is approved by the Board, requires that investments are limited to certain money market and 
treasury  instruments,  and  that  the  Group’s  exposure  to  any  single  bank,  building  society  or  market  is  controlled,  with 
maximum  deposits  allowed  with  any  single  counterparty.    The  investment  criteria  cover  credit  rating  and  asset  size, 
including sovereign and political risk.  Current market conditions have resulted in closer monitoring of counterparties. 

(j) Capital risk 
The primary objective of the Group’s capital management is to ensure that it maintains a strong credit rating and healthy 
credit ratios in order to support its business and maximise shareholder value. 

The Group monitors capital using gearing ratios for the Group and NWL.  These have been revised this year to focus on 
the financial covenants underpinning the Group’s private placement and the committed bank facilities at NWL, which are 
reported to each Board meeting.  The Group’s policy is to keep the gearing ratio less than 80% and 77.5% for the Group 
and NWL, respectively. 

The RCV at 31 March 2018 was £4,182.2 million (2017: £4,014.2 million).  On this basis and excluding shareholder loan 
notes, the gearing ratios were 73% for the Group and 68% for NWL. 

(k) Contractual maturity of financial liabilities (principal and future interest payments) 
The  table  below  summarises  the  maturity  profile  of  the  Group’s  financial  liabilities  based  on  contractual  undiscounted 
payments:

(m) Currency exposures 
At 31 March 2018,  after taking into  account the effects of forward foreign exchange contracts, with the  exception of the 
impact  of  translating  the  net  assets  of  foreign  operations  into  sterling,  the  Group  had  no  material  currency  exposures 
(2017:  £nil).  At  31  March  2018,  the  Group  held  forward  foreign  exchange  contracts  with  a  future  transaction  value  of 
£7.2m  (2017:  £7.0m) for the  purpose of hedging the foreign  currency risk of committed  future  purchases.  At 31 March 
2018, the fair value  loss on the Company’s outstanding foreign exchange contracts was £0.2 million (2017: £0.5 million 
gain). 

(n) Borrowing facilities 
The Group has various undrawn committed borrowing facilities.  The facilities available in respect of which all conditions 
precedent have been met, are as follows:

The fair values of the derivatives and sterling denominated long term fixed rate and index linked debt with a book value of 
£2,696.5  million  (2017:  £2,624.5  million),  have  been  determined  by  reference  to  prices  available  from  the  markets  on 
which  the  instruments  involved  are  traded.    All  the  other  fair  values  shown  above  have  been  calculated  by  discounting 
cash flows at prevailing interest rates.

In  the  absence  of  an  openly  traded  market  value  for the  index  linked  bonds  with  a  book  value  of  £593.6  million  (2017: 
£526.6 million), the fair value at the balance sheet date has been calculated by considering the remaining debt maturity, 
the relevant UK index linked gilt rate and an appropriate credit spread by reference to market evidence for conventional 
bonds. 

The difference between the principal value of £4,276.4 million (2017: £4,120.5 million) and the carrying value of £4,260.2 
million  (2017:  £4,108.6  million)  is  unamortised  issue  costs  of  £30.6  million  (2017:  £29.5  million)  and  a  credit  of  £14.4 
million (2017: £17.6 million) in excess of the original loan proceeds to reflect the fair value of loans owed by subsidiaries 
acquired in 2003.

Cash flow hedges – interest rate swap 
At 31 March 2018 and at 31 March 2017, the Group held two interest rate swaps, designated as hedges of future interest 
cash  flows,  for  which  the  Group  has  firm  commitments.    These  swaps  were  used  to  convert  variable  rate  interest 
payments to a fixed rate basis.  The terms of these swaps were as follows: 

Notional amount 
£100.0 million

Cash flow hedges – inflation swap 
As at 31 March 2018, the Group held three inflation swaps. The first was designated as a hedge of future inflation linked 
cash flows and was used to convert variable inflation-linked revenues on a contract with the EA, to a fixed income stream.  
The  second  and  third  swaps  were  designated  as  hedges  of  future  interest  payments  to  convert  fixed  rate  interest 
payments to index linked interest payments. 

The inflation-linked revenues are accounted for in the consolidated income statement on an accruals basis. However, the 
long-term  inflation  swap  that  fixes  these  variable  cash  flows  is  measured  at  fair  value  with  changes  in  fair  value 
recognised in the income statement. The changes in the fair value reflects the change in the present value of the future 
cash flows which incorporates future expectations of inflation over the full term of the swap.

(q) Fair value hierarchy 
The Group uses the following hierarchy for determining and disclosing the fair value of financial instruments by valuation 
technique: 
 
 

level 1: quoted (unadjusted) prices in active markets for identical assets or liabilities; 
level 2: other techniques for which all inputs which have a significant effect on the recorded fair value are observable, 
either directly or indirectly; and 
level 3: techniques which use inputs which have a significant effect on the recorded fair value that are not based on 
observable market data. 

 

All of the Group’s liabilities are measured at level 2.

The  Group  operates  two  defined  benefit  pension  schemes.    Northumbrian  Water  Pension  Scheme  (NWPS  or  the 
Scheme),  providing  benefits  based  on  final  pensionable  remuneration  to  31  December  2015  and  on  a  career  average 
revalued  earnings  (CARE)  basis  from  1  January  2016,  to  1,244  active  members  at  31  March  2018  (2017:  1,340)  and 
AquaGib  Limited  Pension  Plan  (AGPP),  providing  benefits  based  on  final  pensionable  remuneration  to  59  active 
members at 31 March 2018 (2017: 61). 

The assets of the NWPS and the AGPP are held separately from those of the Group in independently administered funds. 

The most recent actuarial valuation of the NWPS was at 31 December 2016. At that date, the value of assets amounted 
to  £954.6  million  and  the  liabilities  were  £1,242.2  million,  resulting  in  a  deficit  of  £290.6  million  and  a  funding  level  of 
76.7%.  The most recent actuarial valuation of AGPP was at 1 July 2015. At that date, the value of assets amounted to 
£15.4 million and the liabilities were £19.4 million, resulting in a deficit of £4.0 million and a funding level of 79.5%. 

Under  the  revised  schedule  of  contributions  the  future  service  contribution  rate,  jointly  payable  by  members  and  the 
employers,  remained  at  29.4%  of  pensionable  salaries  until  31  December  2017.  With  effect  from  1  January  2018,  the 
employers’ contribution was set at £12.3m per annum, increasing annually by RPI. Employee contribution rates remained 
at between 6% and 8% of pensionable salary, dependent upon which section of the Scheme the employee is a member 
of. 

In addition, the employers continue to make deficit reduction payments of £11 million per annum, with effect from 1 April 
2015, increasing annually by  RPI. Deficit reduction payments  will increase by £2.6 million per annum with effect from 1 
April  2021.  The  deficit  reduction  payments  have  been  set  with  the  objective  of  removing  the  deficit  by  31  March  2031, 
which has been the long-term aim. 

Employer contributions of £25.6 million  were paid in the  year to 31 March 2018, of which £11.3 million related to deficit 
reduction.  For the year to 31 March 2019 employer contributions are projected to be £24.1 million, including £11.8 million 
in respect of deficit reduction. 

Two new activities to manage Scheme liabilities are being implemented in 2018. A pension increase exchange exercise is 
being carried  out and transfer values are being included  in members’ retirement data  with the  Scheme offering to meet 
the cost of one round of financial advice. The potential impact of these activities has not been recognised in the 31 March 
2018 valuation but is expected to be realised in the year to 31 March 2019. 

The Scheme also has a defined contribution section which had 1,945 active members at 31 March 2018 (2017: 1,779).  
Members  can choose  to  contribute  either 3%,  4%  or  5%  of salary,  with  employers contributing  at  either  6%,  7%  or 8% 
depending on the member contribution rate.  The contributions paid to the defined contribution section by the Group in the 
year totalled £5.3 million (2017: £5.1 million). 

The Group has not disclosed the actuarial assumptions for the AGPP on grounds of materiality. 

The additional disclosures regarding the NWPS defined benefit scheme as required under IAS 19 Employee benefits and 
the relevant impact on the financial statements are set out below.  A qualified actuary, using revised assumptions that are 
consistent with the requirements of IAS 19, has updated the actuarial valuations described above as at 31 March 2018.  
Investments have been valued, for this purpose, at fair value.

Nature of benefits, regulatory framework and other entity’s responsibilities for governance of the Scheme  
The  Scheme  is a registered defined benefit scheme subject  to  the UK regulatory  framework for pensions,  including  the 
scheme specific funding requirements.  The Scheme is operated under trust and as such, the Trustee of the Scheme is 
responsible  for  operating  the  Scheme  and  they  have  a  statutory  responsibility  to  act  in  accordance  with  the  Scheme’s 
Trust  Deed  and  Rules,  in  the  best  interest of the  beneficiaries  of the Scheme,  and  UK  legislation (including  Trust  law). 
The Trustee has the power to set the contributions that are paid to the Scheme.  

Risks to which the Scheme exposes the Group  
The  nature  of  the  Scheme  exposes  NWL,  as  the  principal  employer,  to  the  risk  of  paying  unanticipated  additional 
contributions to the Scheme in times of adverse experience. The most financially significant risks are likely to be:  
  members living for longer than expected;  
  higher than expected actual inflation and salary increase experience,  
 
 

lower than expected investment returns, and  
the risk that movements in the value of the Scheme’s liabilities are not met by corresponding movements in the value 
of the Scheme’s assets.  

The sensitivity analysis disclosed is intended to provide an indication of the impact on the value of the Scheme’s liabilities 
of the risks highlighted. Approximate adjustments are made to the defined benefit obligation, reflecting the mean term of 
the liability.  There has been no change in methodology in the year. 

Policy for recognising gains and losses  
The  Group  recognises  actuarial  gains  and  losses  immediately,  through  the  re-measurement  of  the  net  defined  benefit 
liability. 

Asset-liability matching strategies used by the Scheme or the Company  
Neither the Scheme nor the Group use any asset-liability matching strategies. The Trustee’s current investment strategy 
having consulted with NWL is to invest the majority of the Scheme’s assets in a mix of equities and corporate bonds, in 
order to strike a balance between:  
  maximising the returns on the Scheme’s assets, and  
  minimising the risks associated with the lower than expected returns on the Scheme’s assets.

26. PENSIONS AND OTHER POST-RETIREMENT BENEFITS (continued) 

The  Trustee  is  required  to  regularly  review  their  investment  strategy  in  light  of  the  revised  term  and  nature  of  the 
Scheme’s liabilities.  

Description of funding arrangements and funding policy that affect future contributions  
The main risk to the Group is that additional contributions are required if the investment returns are not sufficient to pay 
for the benefits (which will be mainly influenced by inflation and the longevity of members).  The level of corporate bond 
and equity returns will be a key factor in the overall investment return. The investment portfolio is also subject to a range 
of other risks typical of the assets held, in particular credit risk on bonds and exposure to the property market. 

Methods and assumptions used in preparing the sensitivity analyses  
The  sensitivities  disclosed  were  calculated  using  methods  taking  into  account  the  duration  of  the  Scheme’s  liabilities. 
Assumptions were provided by the Group. 

Sensitivity to key assumptions 
IAS  1  Presentation  of  Financial  Statements  requires  disclosure  of  the  sensitivity  of  the  results  to  the  methods  and 
assumptions used. 

The costs of a pension arrangement require estimates regarding future experience.  The financial assumptions used for 
IAS 19 reporting are the responsibility of the Directors of the Company.  These assumptions reflect market conditions at 
the  balance  sheet  date.   Changes in market  conditions which  result in  changes in the  net discount rate (essentially the 
difference  between  the  discount  rate  and  the  assumed  rates  of  increases  of  salaries,  deferred  pension  revaluation  or 
pensions in payment), can have a significant effect on the value of the liabilities reported. 

Change in assumptions compared with actuarial assumptions for the NWPS: 

0.5% decrease in discount rate 
1 year increase in life expectancy 
-0.5% change in inflation 
Notes: 
1.   The change in benefits to CARE means that the liabilities are no longer linked to the salary increase assumption.

As  noted  under  accounting  policy  1(b),  in  accordance  with  IFRS  10  Consolidated  Financial  Statements  and  IFRS  12 
Disclosure of Interests in Other Entities, the financial statements of two companies are consolidated as special purpose 
entities.   The principal special  purpose entity  is  Bakethin  Holdings  Limited,  the  shares in  which  are owned by  Bakethin 
Charitable  Trust.    The  other  special  purpose  entity  is  Bakethin  Finance  Plc,  which  is  a  wholly  owned  subsidiary  of 
Bakethin Holdings Limited. 

Bakethin  Finance  Plc  was  established  for  the  purpose  of  issuing  guaranteed  secured  Eurobonds.    On  12  May  2004, 
Bakethin Finance Plc issued £248.0 million of guaranteed secured bonds maturing January 2034.  Bakethin Finance Plc 
used  the  proceeds  of  the bond  issue  to  make  a  loan  to  Reiver  Finance  Limited  to  fund  the  consideration  given  by  that 
company to Northumbrian Water Limited for the securitisation of the cash flows receivable from the EA under the Water 
Resources Operating Agreement relating to Kielder Water transfer scheme.  The assignment is for a period of 30 years.

On  3  January  2018,  the  Group  increased  its  shareholding  in  Gascorp  Limited  (Gascorp)  from  50%  to  100%  for  nil 
consideration.    The  Group  previously  accounted  for  its  interest  in  Gascorp  using  the  equity  method.    Following  the 
increase in shareholding, Gascorp is fully consolidated into the Group’s results.

The  fair  value  of  property,  plant  and  equipment  reflects  the  long  term  viability  of  the  project  over  the  20  year  life  with 
reference to the latest financial model. 

From the date of acquisition, 3 January 2018, Gascorp has contributed revenue to the Group of £0.5 million and a loss to 
the Group of £0.6 million.  If the acquisition had taken place at the beginning of the year, the revenue of the Group would 
have been £872.4 million and the profit for the Group would have been £71.7 million. 

31. ULTIMATE PARENT COMPANY 

In the Directors’ opinion, the immediate and ultimate parent undertaking and controlling party of NWG, and therefore the 
Company, is CK Hutchison Holdings Limited (CKHH), a company listed on the Hong Kong Stock Exchange.  This is the 
parent undertaking of the smallest and largest group of undertakings for which group financial statements are drawn up

NOTES TO THE COMPANY FINANCIAL STATEMENTS 
for the year ended 31 March 2018 

1. ACCOUNTING POLICIES 

(a) Basis of accounting 
The  Company  meets  the  definition  of  a  qualifying  entity  under  FRS  101  issued  by  the  Financial  Reporting  Council. 
Accordingly, these financial statements were prepared in accordance with FRS 101 ‘Reduced Disclosure Framework’ as 
issued by the Financial Reporting Council. 

As permitted by FRS 101, the Company has taken advantage of the disclosure exemptions available under that standard 
in relation to presentation of a cash flow statement, financial instruments, standards not yet effective and remuneration of 
key  management  personnel.    As  permitted  by  section  408  of  the  Companies  Act  2006,  no  profit  and  loss  account  has 
been presented for the parent Company. 

Where relevant, equivalent disclosures have been given in the group accounts of NWG. 

The  financial  statements  have  been  prepared  under  the  historical  cost  convention  for  the  parent  Company  only.    The 
Company is a private company, limited by shares and is registered, incorporated and domiciled in England and Wales. 

The principal accounting policies adopted are set out below. 

The  financial  statements  have  been  prepared  on  a  going  concern  basis  which  assumes  that  the  Company  will  have 
adequate funding to meet its liabilities as they fall due in the foreseeable future.  As at 31 March 2018, the Company had 
net  current  liabilities  of  £25.8  million  (2017:  net  current  assets  £58.9  million).    The  Directors  have  reviewed  the 
Company’s  cash  flow  requirements  and  available  resources  and  believe  it  is  appropriate  to  prepare  the  financial 
statements on a going concern basis. 

Adoption of new and revised Standards 
Amendments to IFRSs and the new Interpretation that are mandatorily effective for the current year 
In the current year, the Company has applied a number of amendments to IFRSs issued by the International Accounting 
Standards Board (IASB) that are mandatorily effective for an accounting period that  begins on or after 1 January  2017.  
Their  adoption  has  not  had  any  material  impact  on  the  disclosures  or  on  the  amounts  reported  in  these  financial 
statements. 

(b) Fixed asset investments 
Fixed asset investments are stated at their purchase cost, less any provision for impairment. 

(c) Loan receivables 
Loan receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active 
market, do not qualify as trading assets and have not been designated as either fair value through the income statement 
or available for sale.  Gains and losses are recognised in income when the investments are de-recognised or impaired, as 
well as through the amortisation process. 

(d) Interest bearing loans and borrowings 
All  loans  and  borrowings  are  initially  stated  at  the  amount  of  the  net  proceeds,  being  fair  value  of  the  consideration 
received net of issue costs associated with the borrowing.  Finance costs (including issue costs) are taken to the income 
statement  over  the  term  of  the  debt  at  a  constant  rate  on  the  balance  sheet  carrying  amount.    The  carrying  amount  is 
increased by the finance charges amortised and reduced by payments made in respect of the accounting period. 

(e) Employees 
Excluding the Directors, there are no employees in the Company (2017: nil).

NOTES TO THE COMPANY FINANCIAL STATEMENTS 
for the year ended 31 March 2018 

1. ACCOUNTING POLICIES (continued) 

(f) Taxation 
Current tax 
The tax currently payable is based on taxable profit for the year.  Taxable profit differs from net profit as reported in the 
income statement 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 Company’s liability for current tax is calculated using tax 
rates that have been enacted or substantively enacted by the balance sheet date 

Deferred tax 
Deferred tax is the tax expected to be payable or recoverable on differences between the carrying amounts 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 liabilities are generally recognised for all taxable 
temporary differences and deferred tax assets are recognised to the extent that it is probable that taxable profits will be 
available against which deductible temporary differences can be utilised. 

Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset 
is realised based on tax laws and rates that have been enacted or substantively enacted at the balance sheet date. 

The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner 
in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets 
and liabilities. 

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against 
current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Company intends 
to settle its current tax assets and liabilities on a net basis. 

Current tax and deferred tax for the year 
Current and deferred tax are recognised in profit or loss, except when they relate to items that are recognised in other 
comprehensive income or directly in equity, in which case, the current and deferred tax are also recognised in other 
comprehensive income or directly in equity respectively. 

(g) Significant accounting judgements and key sources of estimation uncertainty 
There are no significant accounting estimates.  The significant accounting judgements were: 
 

the  estimation  of  uncertain  tax  provisions,  which  are  assessed  on  advice  from  independent  tax  advisers  and  the 
status of ongoing discussions with the relevant tax authorities.
