FOR YEAR ENDED 31 MARCH 2022 

BOARD STATEMENT – OUR PURPOSE, VISION AND PERFORMANCE 

This statement sets out how we, the Board of Northumbrian Water Limited, set the company’s aspirations in respect of the 

services we provide to our customers and other stakeholders - both now and into the future; how we are performing against 

our aspirations, and how we structure management rewards to incentivise delivery of these aspirations.  

Driven by our Purpose, and our long-term vision to become the national leader in the provision of sustainable water and 

wastewater services, the Board challenges itself and the Company’s employees, to deliver improved performance each 

year, so that our customers’ high expectations can continue to be met. This requires us to consistently deliver outstanding 

service  to  our  customers  across  our  water  and  wastewater  businesses,  as  well  as  maintaining  the  highest  levels  of 

environmental performance.  

We  are  also  clear  that  to  be  the  national  leader  means  to  continue  raising  the  bar  to  improve  standards  further  and 

delivering leadership and showing support for our region and communities in the face of climate change and the challenges 

it brings is vital. Our Route-map to Net Zero adds to our genuine commitment to the environment using renewable energy, 

sustainable management of our land, and our leading efforts to support vulnerable people and our communities. 

How we set our aspirations  

The aspirations we set for the current price control period 2020-25 were developed through extensive engagement and 

consultation with customers and other stakeholders throughout our business planning process. Through this engagement, 

the  company  agreed  updates  to  our  Outcomes  for  customer  service,  the  environment,  and  the  way  we  manage  the 

business. For each Outcome, we agreed challenging Performance Commitments (PCs) which we use to monitor and report 

on our performance.  

In this report, we set out our Outcomes and how we deliver these across our strategic themes, as well  as through our 

Purpose and Values. We report on our performance against our Outcomes and PCs in this report.  

However, to drive the year-on-year performance improvements necessary to deliver our Vision of being national leader, 

we set ourselves tougher, stretching targets within the business. These targets are reported internally through a balanced 

scorecard of key performance indicators which cover the full range of strategic themes that support our Vision. We re-set 

these targets each year, taking account of how other companies in the industry have performed and what our customers 

have told us about their priorities.  

We  also  work  closely  with  the  Water  Forum,  which  brings  together  expertise  from  a  wide  range  of  stakeholders.  Our 

Independent  Non-Executive  Directors,  and  Executive  Directors,  regularly  attend  Forum  meetings  and  workshops.  This 

ensures that the Board directly understands the areas where Forum members are challenging us to improve performance 

and Outcomes for our customers and stakeholders.  

To  align  the  Executive  Leadership  Team’s  focus  with  the  business  Outcomes  we  want  to  attain,  performance-related 

elements of pay are dependent upon the achievement of stretching internal targets from across our balanced scorecard of 

performance measures. Both short-term and long-term incentive plans are structured with 60% related to targets delivering 

benefits for customers and the environment and 40% related to financial targets. The Remuneration Committee Report is 

available  within  our  Annual  Report  and  Financial  Statements  and  provides  full,  transparent  detail  on  our  directors’ 

remuneration policy and how remuneration in the year has been calculated.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT 
FOR YEAR ENDED 31 MARCH 2022 

Performance in 2021/22 

This report describes our performance in 2020/21 against our Performance Commitments (PCs) in detail. 

We’re  delighted  to  have  achieved  our  ambition  to  be  in  the  top  two  companies  for  C-MeX,  the  measure  for  customer 

experience and to have hit our water poverty target, especially given the  current economic climate and the cost-of-living 

crisis our customers are facing.  

We are very proud to have scored significantly above average in many categories in the 2021 Water Matters Report carried 

out by CCW in relation to satisfaction with value for money, trust and customers saying we care about the service we give. 

We are delighted to once again have achieved the top four-star rating in the Environment Agency’s most recent annual 

Environmental Performance Assessment, securing a ‘green’ assessment in areas such as serious pollution incidents and 

self-reported pollution incidents among others.  

We’re on track with WINEP delivery and our bioresources record remains at 100%, however, we were disappointed to 

narrowly miss out on our target for treatment works compliance. We are on track for our ambitious goal to achieve net-zero 

status in relation to our operational greenhouse gas emissions by 2027, having already reduced our carbon emissions by 

over 68% since 2019.   

We performed well on many customer-focused measures of water asset health, such as, discoloured water contacts, taste 

and smell contacts, AIM, risk of severe restrictions in a drought, unplanned outages, water mains repairs and visible leak 

repairs. We were disappointed not to achieve our leakage targets in both our operating areas this year.  

The full impact of Storm Arwen resulted in us failing our targets in all three Interruptions to supply measures. We were 

disappointed not to achieve our drinking water quality PC but are confident that improvement activities have been identified 

to achieve the new Compliance Risk Index measure in future.  

Our  sewer  flooding  improvement  plan  has  continued  to  deliver  results,  with  key  initiatives  making  significant  and 

quantifiable impacts in the areas they are targeting, especially in relation to repeat sewer flooding. However, our targets 

for sewer flooding are enormously challenging and despite delivering a step change in performance in 20/21, we have 

more to do to achieve our goal, 

We welcome the key role that the Water Forum play in providing challenge on behalf of our customers. As part of this 

process,  we  report  to  and  discuss  our  performance  with  the  Water  Forum  and  they  provide  their  independent 

commentary on pages 9 to 11.  

Looking to the future 

We have recently published A Vision for our Coasts and Rivers, a report that outlines the pledges and how we will play 

our part in enhancing the local environment. It details our new long-term commitments to water quality, and our programme 

of work to 2025 that will help us achieve our goals. 

Listening to our customers and having a deep understanding of what they expect from us now and in the future is important 

to  us.  Specifically,  for  PR24  business  planning,  we  have  developed  a  bespoke  programme  of  customer  research  and 

engagement that will allow us to seek our customers’ views on key elements of our future plans, including our long-term 

strategies.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

We’re pleased that the upcoming price review will focus on delivering greater environmental and social value as we already 

work hard to protect our rivers and beaches, and make sure we spend at least 60p in every pound with local suppliers.  

As a Board, we remain committed to continuing our drive to be the national leader and to deliver outstanding service to 

our customers and other stakeholders both for now and into the future.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

CEO’S WELCOME 

I would like to take this opportunity to thank our teams across the business for their flexibility and adaptability as we’ve 

continued to provide essential services while the pandemic continued to affect us. Thankfully, we have begun the process 

of returning to more normal working arrangements and I am delighted we remain one of the leaders in our industry under 

these challenging circumstances.  

We take our responsibility towards the environment very seriously and remain committed to pursuing our goals to reduce 

carbon emissions and waste. I’m proud that we’ve been named on the World’s Most Ethical Companies list, compiled by 

the Ethisphere Institute, for the eleventh time, the only water company recognised. This reflects our work supporting our 

people and embedding an ethical approach and a strong sense of purpose in our culture. 

After making sustained progress since 2017/18 we are delighted to have now reached our ambitious local spending goal, 

ensuring that 60p in every £1 we spend is spent locally, changing lives for the better in our regions. I am also proud of the 

great progress we have made in tackling affordability, a hugely important topic for our customers. The challenges faced by 

households through Covid-19 and the impact of high inflation on energy bills and food prices make this as important as 

ever.  

Benchmarking ourselves against others inspires us to constantly find new ways to innovate and improve. We have worked 

hard to exceed our stretching targets in many areas, building on our strong track record in a year that has not been without 

its challenges. 

Customer 

We’re committed to eradicating water poverty in our regions by 2030 and have already reduced this to less than 10%. 

Despite the recent increase, our bills (in NW region) are still the lowest water and sewerage bills in England. 

I am particularly delighted that we have excelled in our customers’ eyes. Our people work hard to get it right ‘first time, fast 

time, every time’, so we can deliver an unrivalled customer experience. C-Mex is Ofwat’s measure of customer experience, 

and I was thrilled to see the results of our effort being reflected in the scores this year, achieving our stretching aim of being 

in the top two in the industry. In July 2022 NW was listed as the top scoring English water company, and ESW second, in 

the  UK  Customer  Service  Index  (data  collected  September  and  October  2021  and  March  and  April  2022),  a  national 

barometer of customer satisfaction published by The Institute of Customer Service. 

Environment  

We were especially pleased to have delivered a good environmental performance, including retaining a 4* EPA from the 

EA and we are well on course to exceed our Net Zero target by 2027. In April 2022 we published ‘A Vision for Our Coasts 

and Rivers’ which includes nine pledges we believe will be effective for our unique water environment and make a real 

difference  to  our  communities.  Expectations  of  the  water  industry  are  changing.  Increased  challenges  around  climate 

change and population growth mean simply meeting current obligations won’t be enough in the future. While we already 

perform relatively well against the recommendations recently laid out in Ofwat and CCW’s joint sewer flooding research 

report, we recognise that areas for improvement exist.  

We continue to work in partnership with others as water quality can be affected by many different sources. For example, 

we have worked with Marske Litter Action, a local community group committed to improving the coastal area, to develop 

public understanding of our wastewater system and promote our Bin The Wipe campaign.

FOR YEAR ENDED 31 MARCH 2022 

Water 

We continue to meet the challenges of a changing climate, including facing one of the most powerful winter storms on 

record  in  our  northern  operating  area,  Storm  Arwen.  Taking  into  account  the  exceptional  impacts  of  Storm  Arwen,  our 

performance to keep the water flowing for our customers remains at the forefront of the industry. I was enormously proud 

of the response of our teams to battle through extreme conditions to return supply for customers as quickly as possible. 

Our focus is on making the right long-term decisions to ensure a reliable and resilient supply. We are planning now for 

future challenges, such as longer periods of dry weather and an increase in non-household demand in Suffolk. Tackling 

leaky loos remains a key component of our water efficiency strategy as we face the continued challenges of climate change. 

Once again, we delivered on the customer focused aspects of water quality, like taste and smell and discoloured water, 

but there remain areas where we strive to do better. We have agreed a plan for water quality with the DWI for which we 

are currently on track. Our innovation focus continues and we’re developing exciting plans using digital twins of the network 

to tackle problem areas. We were pleased to have reduced the time it takes us to repair customer-reported visible leaks, 

something our customers tell us is very important to them and demonstrates that we are listening and responding to their 

priorities. 

Our People and the Communities we serve 

Having an engaged, healthy, and diverse workforce is critical for our business success. We developed our ‘Together for 

Inclusion, Diversity and Equity’ strategy this year, which alongside our award-winning programmes on employee health, 

contributed  to  us  being  named  in  the  top  35  Great  Places  to  Work  survey  (super-large  category)  for  the  second  year 

running. We were absolutely delighted to be the first and only water company to achieve the Good Business Charter (GBC) 

accreditation, recognising us for responsible business practices. 

We’re  finding  new  ways  to  make  sure  the  economic  benefit  of  our  spending  is  maximised  in  our  regions,  as  per  our 

commitment to supporting local communities, and remain committed to spending 60p in every £1 in region.  

Looking Forward 

We are making further progress towards the ambitious goals we set in Our Plan and will continue to drive this forward over 

the  coming  year.  I  know  we  are  building  on  strong  foundations  in  areas  such  as  customer  service  and  environmental 

performance. Equally we must improve our performance across water quality, leakage, and sewer flooding, investing in 

the  resilience  of  our  assets.  We  have  already  begun  talking  to  customers  and  stakeholders  about  our  next  regulatory 

Business Plan, focusing on understanding and planning for long-term challenges around climate change, economic and 

population changes, changes to customer behaviours and expectations, and developing investment priorities.  

We will also continue to work with the EA and Ofwat on their environmental investigations at wastewater treatment works 

(at four out of 189 locations) and have already acted to make improvements. Collaboration is key as we strive towards 

globally important climate change goals and improving the water environment and biodiversity on our landholdings. We 

are proud of our achievements to date, but never complacent and will continue to make further service improvements.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

WATER FORUM STATEMENT  

Each year, members of the Water Forum, NWL’s independent Customer Challenge Group (CCG), have the opportunity to 

review the company’s results against the promises made to its customers when agreeing its business plan with Ofwat.  

This review covers the 12 months to the end of March 2022: a period during which the country emerged from the pandemic, 

with new work trends that have directly impacted water consumption patterns; towards the end of which international geo-

political issues kickstarted a ‘cost of living crisis’ in the UK and the return of an inflationary economy; and throughout which 

the impacts of climate change continued to be observed and felt. These factors will all continue to be extremely influential 

in the year ahead, so they have been front of mind when considering the comments and challenges offered below.  

Customer Service: In 2021 we challenged the company to review its contact centre resource provision, as customers were 

waiting  too  long  for  calls  to  be  answered  and  call  ‘drop  out’  rates  were  high.  NWL  completed  a  review  and  increased 

resource,  customers  are  getting  their  calls  answered  more  quickly,  which  is  a  step  in  the  right  direction.  We  urge  the 

company to take further measures in the 2022-23 to continue the progress achieved so far, especially given that when 

customers get through, the contact centre team handles cases well – as evidenced by the second highest score nationally 

against Ofwat’s measure of Customer Experience (C-MeX).  

Water Poverty and Customers in Vulnerable Circumstances: We are very pleased that NWL has beaten its annual target 

for the percentage of households receiving assistance and therefore being out of water poverty – a key contributory factor 

was the significant work done with the Department for Work and Pensions to overcome the barriers to data sharing. As the 

cost of living continues to grow amid inflationary pressures, meeting its targets for 2022-23 and beyond will require NWL’s 

leadership and involvement in more initiatives of this kind – in both the public and private sectors – and we hope to see 

the momentum continue. 

We are surprised at the below-target awareness levels of financial and non-financial support that is available to customers 

and have challenged the company to understand why this is, so that it can take appropriate action to meet future targets. 

Customers who are aware of and receive such support are satisfied (as the performance data on page 19 shows), so it 

may be worth NWL considering how it could use this positive result in its approach.  

Environment: Water Forum members are pleased to note NWL’s commitment to and performance in many aspects of its 

environmental impact – most notably the out-performance by a factor of three in both its greenhouse gas emissions and 

its ‘water environment improvements’ measures.  

The company’s retention of the 4-star Environmental Performance Assessment (EPA) rating from the Environment Agency 

is very positive; on the other hand, it is disappointing that treatment works discharge compliance levels dropped in 2021-

22. We acknowledge NWL’s increased focus on this area and hope that the measures being taken will reverse this situation 

in the coming year.  

Customers using the 32 ‘good or excellent’ coastal bathing waters in the Northumbrian Water region will undoubtedly be 

pleased at their quality ratings. As highlighted within this report, one bathing water, Marsden, meets the sufficient standard 

and the multi-party collaborative work to understand the root cause of the bathing water quality issue at the 34th location, 

Cullercoats Bay, is progressing and we remain hopeful of a resolution. 

We would like to commend NWL on the way it handled the Saltburn situation in February 2022, when an emergency sewer 

repair  was  needed  after  a  third-party  incident  –  the  community  was  protected,  the  system  continued  to  operate,  and 

pollution was minimised.  

15 July 2022 
PAGE 9 OF 206 

 
 
 
 
 
NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

Pollution incidents, including those caused by Storm Overflows, are high on the public interest agenda. We are pleased 

that  in  its  wastewater  river  quality  action  plan,  NWL  has  committed  to  improve  its  performance  on  the  use  of  storm 

overflows; and will monitor and provide challenge to the management team as it works towards the targets it has set itself.  

The  company  did  not  meet  its  Ofwat  2021-22  target  for  the  number  of  sites  being  improved  under  the  five-year  Water 

Industry National Environment Programme (WINEP), which runs for another three. We acknowledge, however, that NWL 

is on track against the revised targets agreed with the EA in light of the delays caused by the Covid-19 pandemic.  

Drinking  Water  Quality:  The  ‘Compliance  Risk  Index’  (CRI)  score  stands  out  as  an  area  of  poor  performance  for  the 

company and has attracted a large financial penalty. Our members have stayed close to this critical issue throughout the 

year  and  understand  it  well.  The  large  transformation  programme  that  NWL  is  working  on  with  the  Drinking  Water 

Inspectorate  (DWI)  to  improve  the  CRI  scores  is  a  long-term  one  and,  reassuringly,  we  have  observed  a  number  of 

examples where improvement work should realise the necessary benefits in the measure. 

For those sites included in the future programme, we encourage the company to realise benefits as quickly as possible by 

adopting any lessons learned wherever it can.  

Sewer Flooding: The ‘repeat sewer flooding’ performance measure is one that was included because of challenge from 

the  Water  Forum  during  the  PR19  business  planning  process,  so  we  are  particularly  pleased  to  see  the  company’s 

continued strong performance for its customers. Clearly, there is still much work for NWL to do to achieve some of the 

other  sewer  flooding  targets,  and  customer  behaviour  is  acknowledged  as  being  an  important  factor  –  last  year  we 

challenged the company to use its positive reputation for partnership working to take a lead in a national ‘bin the wipe’ style 

campaign, and we are pleased that the company has risen to this challenge and a campaign is now being developed with 

Water UK. 

Water Resources: Pressure on water resources is coming from many angles, particularly in the Essex and Suffolk region 

– many commuters who, pre pandemic, consumed their water in their city offices are now consuming it at home, which is 

reflected  in  the  missed  targets  for  Per  Capita  Consumption  (PCC);  the  effects  of  climate  change  continue  to  have  an 

impact; and leakage remains a tough nut to crack.   

On the latter, although NWL has delivered ahead-of-target performance for its response to visible leaks, overall leakage 

reduction was below target. We understand that many leaks are ‘invisible’ and finding them poses the greatest challenge 

in  meeting  these  targets  –  we  are  therefore  encouraged  by  the  innovative  National  Leakage  Research  &  Test  Centre 

project and look forward to seeing the results it delivers.  

For its Water Resource Management Plan (WRMP) to succeed, we believe that there is a real need for the company to 

engage holistically and comprehensively with the public on the nature of the water resource challenge and the part that 

each  party  could  play  in  resolving  it.  Anecdotally,  customers  have  low  awareness  of  the  problem  but  very  much  a 

willingness to work with NW/ESW to improve the position.  

Weather and asset resilience: November’s Storm Arwen clearly had a large, adverse impact on all ‘interruptions to supply’ 

performance measures. And although the biggest issues were due to Northern Power Grid’s challenges, we urge NWL to 

take the actions it has outlined in order to improve the water network’s operational resilience in the event of power outages 

in future. To deliver more for less, there may be opportunities to work in partnership with the industry and with the power 

distribution  sector  too.  From  a  strategic  planning  point  of  view,  Arwen  has  also  shone  a  light  on  the  importance  of 

considering  different  types  of  storm  and  weather  events,  such  as  flash  flooding  and  freeze-thaw  events,  which  are 

increasing in frequency and intensity as a result of climate change – the industry as a whole needs to be fully prepared for,

FOR YEAR ENDED 31 MARCH 2022 

and resilient to, such weather events, as we consider them to now be ‘business as usual’ rather than rare occurrences. In 

conclusion,  the  Water  Forum  look  forward  to  seeing  what  the  company  can  deliver  for  its  customers  in  2022-23;  and 

between  now  and  then  our  members  will  continue  to  fulfil  their  role  of  providing  independent  challenge,  insights  and 

expertise throughout the delivery of the current business plan and in the development of the plans for the next Ofwat review 

of prices in 2024 (PR24).

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

ASSURANCE SUMMARY 

Within this Annual Performance Report, we publish a range of information about our services and performance, including 

how  we’re  performing  against  the  commitments  we  made  in  our  2020-25  Business  Plan.  This  helps  to  provide  our 

customers and stakeholders with assurance that we’re delivering what they’ve told us they need and want from us. 

It’s  important  that  we  have  robust  assurance  arrangements  to  make  sure  this  information  is  accurate,  clear,  and 

transparent.  

This is essential to building and maintaining a high level of trust and confidence with our customers and stakeholders.In 

March  2022,  following  consultation  with  customers  and  stakeholders,  we  published  our  Assurance  Plan  for  2022/23. 

Consistent with guidance from our economic regulator (Ofwat), this document firstly assessed any strengths, risks and 

weaknesses  associated  with  either  meeting  our  obligations  and  commitments  or  providing  information  of  appropriate 

quality. It then detailed the checks and balances (assurance) we planned to carry out to address these risks and make 

sure we remain on track. 

A  significant  proportion  of  our  assurance  is  targeted  at  making  sure  that  the  information  we  publish  in  our  Annual 

Performance  Report  is  of  appropriate  quality.  We’ve  published  a  Data  Assurance  Summary  alongside  this  Annual 

Performance Report. This details how we decide what level of assurance should be applied to our data (i.e. who should 

provide the assurance), and whether this has been completed during the year. It also details key findings and, in conclusion, 

confirms that there were no significant issues to report.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

INTRODUCTION 

This report summarises our performance against our Outcomes during the regulatory year ending 31 March 2022. This is 

the second year of us delivering our 2020-25 Business Plan.  

Our drive to be the best is supported by six strategic themes: Unrivalled customer experience; affordable and inclusive 

services;  leading  in  innovation;  reliable  and  resilient  services;  improving  the  environment  and  building  successful 

economies in our regions. Our Outcomes are aligned to these themes and set out what we aim to achieve. They represent 

what our customers have told us they value in the long-term. They are our commitments, or promises, to our customers.  

Our 14 Outcomes were developed with our customers and stakeholders. Everything we do is driven by an Outcome for 

our customers.  

To  track  performance  against  our  Outcomes  we  have  clear  metrics  with  associated  targets  –  our  Performance 

Commitments (PCs). For delivering better performance in certain measures, we could earn a financial reward. Conversely, 

poor performance in certain measures could incur a financial penalty. These rewards and penalties are called Outcome 

Delivery Incentives (ODIs). Some of our performance measures are simply reputational, which means that they do not 

incur financial penalties or rewards.  

This performance report sets out the work that we are doing to deliver our 2020-25 PCs along with our progress towards 

the longer-term goals which we’ve set.  

The report provides extended commentary for tables 3A to 3I, which is a summary of our performance against our PCs 

that we must provide for our regulator (Ofwat) every year.  

We  measure  our  performance  and  calculate  any  penalties  or  rewards  using  the  methodology  in  our  PR19  Final 

Determination, along with any subsequent amends set out in the CMA’s recent redetermination.  

This reporting process is subject to robust assurance, as set out in the Data Assurance Summary. Further information 

about our performance is available on our website www.nwg.co.uk.  For information about how we are performing in 
comparison to other water and sewerage companies, visit www.discoverwater.co.uk.

We  have  strived  to  deliver  our  PCs  in  what  has  been  a  challenging  year  due  to  the  ongoing  impacts  of  Covid-19,  a 

deteriorating economic and political climate, and the constraints imposed by Ofwat’s Final Determination for 2020-25.  

We’re pleased to have achieved or beaten 24 out of our 42 PCs in 2021/22. This excludes the final assessment of C-MeX 

and D-MeX, and AIM, which was not activated in 2021/22. 

The table above shows we earned rewards for 11 of these achievements, excluding the final confirmation of C-MEX and 

D-MEX rewards. Of the remaining 12 commitments we achieved, nine were reputational only and two penalty only (Bathing 

Waters PC was achieved but not surpassed leading to no reward). 

We accrued penalties for not meeting nine of our PCs this year and did not achieve eight of our reputational only PCs (nine 

including  per  capita  consumption  which  will  be  reviewed  at  the  end  of  the  AMP  in  relation  to  levels  of  rewards  and 

penalties). While there have been some setbacks this year regarding progress towards our longer-term ambitious goals, 

we’re committed to continuing to strive to achieve them. 

Headlines include:  

•  We  are  absolutely  delighted  to  have  achieved  our  ambition  of  being  in  the  top  two  companies  for  C-MeX  in 

2021/22, the industry-wide measure that provides a holistic comparison of companies’ customer satisfaction and 

experience performance. 

•  We are also delighted to have beaten our water poverty target, keeping us on track to deliver our  ambition to 

eradicate water poverty in our operating areas by 2030. This has been especially challenging given the current 

economic climate. 

•  We’ve  delivered  a  small  improvement  in  our  water  quality  compliance  (CRI)  but  remain  disappointed  not  to 

achieve our PC. We’re committed to achieving industry leading levels of CRI and are delivering our long-term 

plans to reach this.  

•  On  leakage  it  is  proving  more  challenging  than  expected  to  deliver  the  targeted  reductions,  and  we  are 

disappointed not to achieve our target in either operating area. We are pleased, however, to have beaten our 

target for responding to customer reported visible leaks.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

• 

In late November 2021 Storm Arwen resulted in widespread and sustained power outages across the North East 

– triggering a civil emergency. The power outages also affected our ability to provide water to a number of our 

customers. Consistent with the terms of our three performance commitments for Interruptions to Supply, we have 

made  a  representation  to  Ofwat  for  the  majority  of  the  impact  of  the  Storm  to  be  excluded  from  our  reported 

performance.  Should  Ofwat  accept  this,  we  expect  to  incur  a  small  penalty  for  the  year  across  our  three 

interruptions measures of £0.57M.  

•  Our sewer flooding improvement plan has continued to deliver results, with key initiatives making significant and 

quantifiable impacts in the areas they are targeting. We have significantly outperformed our PC in repeat sewer 

flooding but our targets for sewer flooding are challenging and we have more to do to achieve our goal.  

•  We remain committed to our ambition to have the best rivers and beaches in the country, and recently published 

our Vision for Coasts and Rivers. We continue to beat our PC for Pollution Incidents and achieve our PC for 

Bathing  Water  Quality.  We  are  disappointed  to  marginally  miss  our  target  for  Treatment  Works  Discharge 

Compliance,  however,  are  delighted  to  retain  our  4-star  company  status  in  the  Environmental  Performance 

Assessment (EPA) from the EA. 

•  We’re  also  pleased  to  have  again  beaten  our  target  (by  a  factor  of  three)  for  delivering  Water  Environment 

Improvements. 

•  Our performance overall has created a net reward of £2.534M, with a further estimated value of £3.996M related 

to C-MEX and D-MEX performance. 

In addition to the commitments outlined in the table above, we have PCs to make sure we deliver additional investments 

for customers by 2025 including:  

•  Smart metering.  

• 

Lead Pipe Replacement.  

•  Delivery of our water and wastewater resilience programmes. 

•  Howdon Sewage Treatment Works Expansion.  

•  Cyber Resilience.  

•  Drainage & Wastewater Management Plans (DWMPs). 

While progress for Smart Metering and Lead Pipe replacement (which require access to customer properties) has been 

slower than expected due to the pandemic, we remain confident of delivering our commitments by 2025. We are also on 

track with delivery against our wastewater resilience programme, our resilience investment at Howdon, Cyber Resilience, 

and DWMPs.

OUR 2021/22 PERFORMANCE IN DETAIL 

Some of the measures are ‘common’ across the water industry and some are ‘bespoke’ to us. This is flagged next to each 

measure. 

THEME ONE: UNRIVALLED CUSTOMER EXPERIENCE 

OUTCOME 1: our customers tell us we provide excellent customer service and resolve issues 
quickly 

AMBITIOUS GOAL: Deliver world class customer service 

•  Ofwat’s Customer Measure of Experience (C-MeX) – common 

•  Response time to written complaints – bespoke  

•  Ofwat’s Developer Services Measure of Experience (D-MeX) – common 

Customer Measure of Experience (C-MeX) position - PR19NES_COM01 

This is an industry comparative measure, defined by Ofwat. As such, the ranking position is more relevant to report on as 

opposed to the absolute score. 

We are absolutely delighted to have achieved our ambition of being in the top two companies for C-MeX, the industry-wide 

measure that provides a holistic comparison of companies’ customer satisfaction (CSS) and customer experience (CES) 

performance.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

We are passionate about engaging with our customers to understand how they want us to deliver world class customer 

service. Our focus remains on getting things right first time, fast time, every time. We know our customers really value this 

and we always work hard to achieve it. 

After a difficult start to 2021/22, our 3,038 employees pulled together across the business to turn performance around and 

deliver a fantastic overall result for the year through relentless hard work and a real obsession with customer service – this 

is reflected in our 2022 Great Place to Work scores. Over 2,500 of our people took part and 70% said that NWG is a great 

place to work. 

To  improve  CSS  scores,  our  focus  has  been  on  improving  customers’  experiences  when  they  do  get  in  touch.  Where 

written complaints are received, we take a ‘phone first’ approach and always try to contact our customers by phone before 

following up in writing. This makes sure we fully understand their concerns and that they are satisfied with our proposed 

resolution. 

We have put in place robust cross-functional processes to make sure complaints are resolved to customers’ satisfaction 

as  swiftly  and  consistently  as  possible.  This  includes  a  series  of  regular  review  meetings  with  our  customer,  water, 

wastewater, and billing teams. 

In relation to CES, we continue to promote the great work we do through our Just Add Water integrated marketing campaign 

and have ramped up visibility of this in our local communities, promoting the ways in which we can offer help with bills to 

our customers who are struggling to pay.  

We’ve offered at least five contact channels throughout the year, and at least three of them were digital. Examples of our 

channels  include  voice,  automated  interactive  voice  response  (IVR),  email,  webform,  website,  app,  social  media,  and 

messaging. 

We can earn a reward for high performance if we meet each of the following three criteria: 

•  We are one of the top three performers by C-MeX. 

•  We are at, or above, a cross-sector threshold of customer satisfaction performance based on the all-sector upper 

quartile (ASUQ) of the UK Customer Satisfaction Index (UKCSI). 

•  We have lower than the industry average number of household complaints (per 10,000 connections). 

We await Ofwat’s confirmation on the level of our C-MeX reward factoring in the three criteria above but expect this to be 

approximately £3.12M.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

Response time to written complaints (days) - PR19NES_BES03 

We have not achieved our target.  

Our customers told us that the speed with which we respond to complaints was more important to them than minimising 

incidents. This is a bespoke PC. 

This measure uses CCW’s definition of a written complaint, which covers complaints via post, email, web, or fax that are 

responded to within the reporting year. We’re committed to responding to a minimum of 90% of written complaints within 

one working day. To encompass that level of service, and to  maintain appropriate focus on complex complaints which 

cannot be responded to within one day, we set our PC to two working days for 2020-25. This has proven to be an extremely 

stretching target. 

We failed to achieve our target, in part because only substantive and full responses are included in the figure. Covid-19 

has had an impact on response times, particularly from an operations perspective when investigations are needed. Most 

complaints we receive are complex and require in-depth investigations and/or further work to resolve the issue. If we were 

to include holding responses the current response time is around five working days.  

Our  response  time  to  wastewater  complaints  is  poorer  than  that  of  water  and  billing  complaints.  This  can,  again,  be 

explained through the fact that wastewater issues are largely more complex and take longer to fully investigate and resolve. 

While we are disappointed to not achieve our target, we are confident that we are ultimately working with our customers to 

resolve issues to their satisfaction. Customers give good feedback in terms of how we resolve their issues, and they are 

complimentary when they do speak to us. They also tell us that if we keep them informed, they are happy for resolution to 

take that little bit longer to achieve the best outcome. 

We are working hard to not only reduce the number of complaints that we receive but also to put in place robust processes 

which will allow us to improve response times.

Examples of feedback from a satisfied customer whose complaint took longer than two days to resolve: 

Summary:- A loose drain cover was causing noise disturbance and impacting on the mental health of the customer. We 

investigated the issue and resolved it. 

I am writing to inform you of the excellent customer care I have received from one of your team members Sarah. I 

emailed 20 March to report a noisy drain cover in the road near our property which has been keeping me awake for 

months and impacting on my mental health due to lack of sleep. The following day I received a call from Sarah who was 

very understanding and said she would get on to it straight away to see what she could do to get this dealt with asap. 

Sarah kept me informed of her progress and within the week the Groundworkers had fixed the drain. I have now been 

able to sleep, and I cannot thank Sarah enough for her understanding, her prompt action and professionalism. I would be 

most grateful if you would pass on my gratitude and appreciation to Sarah, her customer care has been above 

outstanding. 

Developer Experience (D-MeX) position - PR19NES_COM02 

This is a financial common PC for developer customers looking at a range of Water UK metrics, as well as feedback from 

customers. 

We finished in 5th place and have improved on our position from the previous year with an overall score of 88.56, which is 

above  average.  We  expect  to  receive  a  small  reward  of  approximately  £0.876M  once  Ofwat  has  finalised  figures.  We 

scored a qualitative score of 80.26 and a quantitative score of 93.62. 

To  make  sure  we  check  that  our  performance  against  the  selected  Water  UK  metrics  is  an  accurate  reflection  of  our 

underlying performance in the reporting year, first stage validation is carried out by data providers and then assured by our 

Customer Experience Manager (D-MeX). Validation also includes referring selected performance data to our Developer 

Services Regulation & Compliance Manager. In addition, there is periodic audit of performance from  our Internal Audit 

team. 

To improve on our performance, we made three significant changes to our processes. 

Firstly, customer research told us developer customers wanted to speak directly to the Developer Services team. They told 

us they didn’t want to repeat themselves when queries were redirected from our Contact Centre, but also because they 

would have more knowledge of the developer services processes and understand technical detail.  

In line with our approach to getting things right, first time, fast time, every time – we took inbound developer calls out of 

our  Contact  Centre  and  directed  them  straight  to  the  Developer  Services  team,  significantly  improving  their  customer 

experience. 

We also co-created, with some of our developer services customers, an online portal for water and sewerage connections.  

Applications  can  now  be  submitted  online  along  with  supporting  documents.  Functionality  has  been  included  to  allow 

developers  to  see  all  their  applications  in  one  place,  track  their  progress,  make  payments  online  and  engage  with  our

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

people  so  we  can  best  support  them  with  advice  as  necessary.  The  portal  includes  articles  and  information  relating  to 

frequently ask questions, which allows customers access to self-help themselves if that is their preference.  

Feedback is positive: 

“It’s fantastic piece of kit and it will give me so much more visibility of my applications.”  

“This will make my life so much easier” 

Finally, we recognised that performance in our Northumbrian operating region was poor in comparison to our Essex and 

Suffolk operating region in relation to water service connections. To learn from the good performance in Essex and Suffolk 

we  established  a  working  group  that  reviews  any  individual  service  connection  failure  and  carries  out  a  deep  dive  to 

understand what went wrong, and what learning we can take to improve future performance. The group has also started 

reviewing end to end processes to understand which activities can be carried out in advance or ran in parallel. 

Case study: Top water company in UK customer satisfaction measure  

Northumbrian Water (NW) ranked first place in the water industry and fourth place against all utilities in the latest Institute 

of Customer Service’s UK Customer Satisfaction Index (UKCSI).   

The UKCSI is the national barometer of customer satisfaction. Driven by 45,000 customer responses and covering 13 

sectors of the economy, it gives a unique insight into the quality of customer service in the UK as a whole and is based 

on a six-monthly online survey of consumers which is demographically representative of the UK population. 

This year NW ranked top water company and fourth utility while Essex & Suffolk Water (ESW) ranked seventh water 

company overall and thirteenth in the utilities sector. These are our highest results to date and ESW was also named as 

one of the most improved companies.  

We are very proud of these results and of the hard work by our teams, we will continue to build on this top performance 

for our customers.

Case study: Storm Arwen  

Storm Arwen was an unprecedented and extreme weather event at the end of November 2022 affecting many of our 

customers and our people and assets.   

Despite having to work in extreme conditions, with lots of employees going home to no power in their own homes, they 

still delivered unrivalled customer experience by putting our customers’ needs first.  

Compassionate Craig and his heroic actions 

Driving home from his shift at Fontburn Water Treatment Works, Craig, one of our Production Operators came across a 

family whose car had been hit by a fallen tree. Realising the risk that more trees were in danger of falling and that the 

people were in shock, our caring team member took them to a nearby Travelodge for the night and kept in touch with 

them to make sure they were ok after the incident.   

Mr S wrote to our Customer Care team as he wanted to make sure Craig was recognised for his actions. He said: “If it 

wasn’t for his quick thinking and selflessness, the situation would have been very different as we weren't thinking clearly 

due to shock.”  

Prioritising vulnerable customers  

Residents at Waskerley Reservoir were left without power and drinking water during the storm. Our rural water team 

supplied them with bottled water as they had no indication when Northern Powergrid would be able to restore power due 

to the damage on the network caused by the storm and freezing conditions.  

We then took on a challenge and discussed the potential to fix an old, fixed site generator unit to help supply the elderly 

vulnerable residents with electricity. Trevor from our Maintenance team rose to the challenge of recommissioning a fixed-

site generator which had been abandoned over ten years ago. Armed with his tools and 20 litres of diesel, he worked on 

the generator and was able to get the unit running.  

The team then started checking the electrical circuits were safe to be used and communicated with the residents to let 

them know what was happening. By early afternoon the team had fully checked the system and made sure it was safe to 

use, fully restoring power to the residents at Waskerley Reservoir!  

This was a great effort from all involved and our people really showed their One team, Customer focused and Innovative 

spirit! The residents at Waskerley Reservoir are mainly elderly people who were very thankful to the team for their hard 

work and were delighted to have power back on, as well as their water supply.

OUTCOME 2: Our customers say they feel informed about the services we provide and the 
importance of water 

AMBITIOUS GOAL: Give every single customer the opportunity to have a strong voice and 

engage with us, with at least 2m customers participating by 2025 

Listening to our customers and having a deep understanding of what they expect from us now and in the future is important 

to us. We genuinely put our customers at the heart of everything that we do. 

We listen to our customers daily through operational contact that we have with them, including how we use Rant & Rave 

to understand how we can continually improve the services that we provide based on customers’ feedback.  Whenever we 

have  big  decisions  to  make  about  changes  to  the  services  we  provide  and  how  we  provide  with  them,  we  seek  our 

customers’ views so that we can make sure we provide services in the way that they want us to.  Specifically, for PR24 

business planning, we have developed a bespoke programme of customer research and engagement that will allow us to 

seek our customers’ views on key elements of our future plans, including our long-term strategies. 

Digital contact via our website, app and automated phone system spiked during the first Covid-19 lockdown of March 2020 

and  has  not  returned  to  pre-Covid  levels.  Contact  via  our  website  and  app  is  now  consistently  higher  than  contact  by 

phone. We believe this demonstrates a permanent change in our customers’ contact preferences and are aiming for 72% 

of contact to be digital by the end of 2022. To support this, we’re regularly releasing new features and upgrades to both 

our website and app. Our digital customer experience roadmap is based on customers’ feedback and  priorities and so 

reflects what matters to them:

•  New Priority Services Registration form 
•  New confirmation emails and SMSs for all customers

We’re  confident  that  our  customers  are  having  a  great  experience  with  us  online.  Our  website  consistently  achieves  a 

world class NPS (Net Promoter Score) score of +70 and in November 2021 we were a Silver Award Winner for Best Digital

Case study – Customers invited to have their say on £149M plan to upgrade the water 
network  

We invited our customers to meet the team behind the first phase of a £149M project to upgrade and futureproof our 

water supply network across the south of County Durham and into Teesside. 

‘Project Pipeline: Durham and Tees Valley’ includes replacing some sections of the network that are more than 100 

years old and installing 28km/17 miles of new pipes, connecting Lartington Water Treatment Works with Shildon to make 

sure around 200,000 customers continue to receive clean, clear, and great tasting tap water, each day. 

Our customers were given the opportunity to meet the project team to learn more and discuss the plans at a series of 

community events before we submitted planning application because we recognise the importance of customers 

understanding our aims for improving and futureproofing their water supply, and how we plan to do it. 

We also set up a web page for those who couldn’t attend the events so that they too could have their say. 

Across the four customer engagement sessions, 78 customers, including a reporter for the Teesdale Mercury, attended. 

This gave us an opportunity to talk face to face with those customers and answer their questions and offer explanations 

and reassurances where they had concerns.  

Additionally, the attendance of the journalist, who took the opportunity to talk through the plans with the Project Manager, 

also allowed us to gain further media coverage of the plans in the local area.

OUTCOME 3: our customers say we are a company they trust 

•  Customers’ perception of trust (independent survey) – bespoke 

Customers’ perception of trust (independent survey) - PR19NES_BES05 

We have not achieved our target.  

This measure is the mean customer satisfaction score out of ten from our independent customer tracking survey. The survey 
engages 500 household customers each quarter. There are no financial incentives associated with this bespoke PC. 

Our trust score dipped very slightly to 8.7 out of 10, which is marginally below our PC.  

We want to maintain our usually high score in this area. As a provider of essential services, being trusted is critical – our 

customers should always have highest levels of confidence in the services we provide.  Our ‘Just Add Water’ campaign 

focuses on increasing brand awareness, and we share our good news stories with the media and on social media because 

we want our customers to know us as a valued and respected partner in the communities we serve.  

In CCW’s Water Matters report 2021/22, we were disappointed our trust score in our ESW operating region dropped to 

7.29, but this is still above average across all water companies. In our NW region, our trust score was 7.7, lower than the 

previous year but significantly higher than average for all water and sewerage companies. 73% of participants agreed we 

care about the service we give to customers (NW) and, this was significantly higher than average for all water and sewerage 

companies. 

While we are disappointed to have dipped slightly compared to our usually high performance, however, another year of 

uncertainty has mean that distrust is now the default across the globe (Edelman Trust Barometer 2022).

Case study – Responsible practice recognised in water industry first 

We became the first and only water company to achieve the Good Business Charter (GBC) accreditation, which awards 

ethical businesses by measuring their behaviour over 10 key components.  

The Good Business Charter, which is supported by the Confederation of British Industry (CBI) and the Trades Union 

Congress (TUC), is an independent not-for-profit organisation that encourages and recognises responsible business 

practices including real living wage, fairer hours and contracts, employee well-being, employee representation, diversity 

and inclusion, environmental responsibility, paying fair tax, commitment to customers, ethical sourcing, and prompt 

payment.  

We were absolutely delighted to be recognised, an achievement which is testament to the efforts our teams put in to help 

us reflect our values as we provide a service people couldn’t live without. 

We care passionately for our customers, our communities, our employees and our environment and we’re proud of our 

commitment to put responsible and ethical working practices at the heart of everything we do such as our commitments 

to become carbon neutral by 2027; to eliminate water poverty in our operating areas by 2030 and to help prevent the 

equivalent of four billion plastic bottles ending up as waste by 2030. 

Since 2008, we have cut emissions from 303,000 tonnes of Co2 to 56,000 in 2020 and more than 1,800 of our sites are 

already powered by renewables.  

Our people have also taken time to give something back, with 235 organisations supported annually through our 

employee volunteering scheme, Just an Hour. We also participated in the Laptops 4 Kids scheme, donating hundreds of 

laptops and computers to help support children learning from home during the coronavirus crisis.  

Jenny Herrera, CEO of Good Business Charter, said: “We are so pleased to welcome Northumbrian Water to our rapidly 

growing community of accredited organisations. 

“As such a leader in responsible business behaviour it’s great to have them join the GBC and we hope that they seek to 

inspire many other businesses to follow suit.” 

The GBC accreditation adds to other recognition for ethical practice for us as we were also named the most ethical water 

company in the world for the tenth time in this year’s World’s Most Ethical Company List, published by the Ethisphere 

Institute. We are one of only five UK companies and the only water and sewerage firm in the world to be featured.

OUTCOME 4: Our finances are sound, stable and achieve a fair balance between customers and 
investors. 

There are no PCs under this Outcome. However, we stated in our Business Plan that we will deliver the following for  

customers under this Outcome: 

•  We are financially resilient 

•  We have a financially stable Business Plan 

•  We plan our finances for the long-term 

•  We raise debt finance efficiently 

•  We share any efficiencies we make with customers 

•  We pay our taxes 

•  We procure responsibly 

We have longer term plans to allow us to operate our business sustainably and we manage our finances in the same way 

to make sure they remain sound and stable. It is important that we maintain a fair balance between our customers and 

investors  to  keep  our  customers’  bills  as  low  as  possible  while  continuing  to  attract  capital  to  finance  the  investment 

necessary  to  maintain  and  enhance  our  assets.  Striking  this  balance  shows  our  customers  they  can  have  trust  and 

confidence in us.

Financial structure and resilience 

Like most companies, we are financed through a combination of money from shareholders, profits, and borrowings. NWL 

is a wholly owned subsidiary of Northumbrian Water Group Limited (NWGL), which is majority owned by companies in the 

CK Hutchison Holdings Limited (CKHH) group, based in Hong Kong, who are responsible and committed investors in our 

business. 

The  chart  below  shows  the  summarised  corporate  structure  of  the  Group.  The  chart  shows  the  principal  intermediate 

holding  companies,  which  are  wholly  owned  unless  otherwise  shown.  On  21  May  2021,  CK  Asset  Holdings  Limited 

acquired the Li Ka Shing Foundation’s indirect interest in NWGL. 

CKHH, CK Infrastructure Holdings Limited (CKI), Business Thrive Limited and NWGL have provided Ultimate Controller 

undertakings to the Company in accordance with the provisions of the Company’s Instrument of Appointment (Licence). 

Like any investors, our shareholders expect a return on the money they invested but these dividends are not guaranteed. 

We make sure the dividends are set at a level which is sustainable, remains consistent with our investment grade credit 

ratings and allows us to continuously put money back into the business.

The Board places a strong focus on maintaining long term financial resilience. We maintain a detailed five-year plan that 

is updated regularly and formally reviewed by the Board annually. This is underpinned by a commitment to maintaining an 

investment grade credit rating, as assessed by independent credit rating agencies Moody’s and Standard & Poor’s.  

The Board has assessed our long-term financial resilience over an eight-year period, to the end of the next price review 

cycle. This included stress testing our plan against our most significant risks and uncertainties. The Board’s assessment 

is set out in our long-term viability statement on page 129 of this report.

The revenue that we can charge to customers is set every five years through the regulatory price review process. We aim 

to keep our bills as low as possible while still  allowing us to invest in sustainable and resilient services and allowing  a 

reasonable return to our investors. For 2020-25 we proposed a 15% reduction in customer bills, the largest in the sector. 

We operate and finance our business as efficiently as we can on behalf of our customers, and we share any efficiencies 

we make with them. We aim to be at the frontier of cost efficiency which benefits all water and sewerage customers in 

England because it drives the efficiency frontier, against which all companies are benchmarked, to new levels. 

Customers benefit from sharing the cost efficiencies we make in each price review period. Any outperformance of the totex 

regulatory  allowance  for  2020-25  will  be  shared  with  customers,  resulting  in  lower  future  bills.  They  also  benefit  from 

efficiencies in financing costs so that customers do not pay any more than is necessary. 

Long term borrowings 

We  invest  around  £1M  each  business  day  in  maintaining  and  enhancing  our  asset  base  to  improve  services  for  our 

customers. The scale of this capital expenditure means that we need to supplement the money we receive each year from 

our customers through their bills by borrowing additional money from banks and debt markets. Our investment grade credit 

ratings and strong capital structure help us to obtain financing at competitive interest rates, making sure our financing costs 

stay as efficient as possible for customers. 

We borrow in a controlled and sustainable manner to make sure we can deliver substantial investment in our asset base 

without this leading to a significant increase in customer bills. We spread the financing cost of our investment and manage 

the borrowings over long periods of time, sometimes more than forty years. This means both current and future customers 

help  to  pay  for  the  investment.  As  a  result,  bills  are  more  stable  and  sustainable  for  customers,  with  a  fair  balance  of 

contributions between generations. 

Our  borrowings  range  from  short-term  working  capital  financing  to  long  term  bonds,  typically  listed  on  the  UK  Stock 

Exchange.  Our  borrowings  reflect  a  mix  of  fixed  rate,  providing  stable  interest  costs,  and  inflation-linked,  to  match  our 

inflation linked revenues. By maintaining a well-balanced debt portfolio, we can better manage risks of adverse movements 

in inflation and interest rates and minimise volatility on customer bills. 

Our total borrowings at 31 March 2022 amounted to £3.17bn, as reported in Table 1E of this report.

Shareholder returns 

Our shareholders have provided the necessary capital and financial backing required to run the business and in return 

they receive a dividend return on the capital they have invested. The dividends we can pay are driven by our financial and 

operational performance, the level of service provided to our customers and employee’s interests. This means that the 

returns  our  shareholders  receive  are  not  guaranteed  from  one  year  to  the  next  and  we  paid  no  dividends  in  the  year 

2020/21 as a result of the impact of the PR19 Final Determination and the uncertainty surrounding the CMA redetermination 

process and the impact of Covid-19. There are many significant risks associated with the business and it is the shareholders 

rather than our customers who carry the weight of these risks. 

We make sure the dividends are set at a level which is sustainable, remains consistent with our investment grade credit 

ratings and allows us to continuously put money back in the business. Our dividend policy is described on page 175 along 

with an explanation of how the directors have applied the policy in the year. 

Taxes 

Both NWL and our parent company, NWGL, are based in the UK and pay corporation tax to the UK Government. We are 

transparent about our tax arrangements and present our Tax Strategy on page 154 of this report, as well our website. This 

sets  out  our  responsible  approach  to  tax  matters,  under  the  oversight  of  the  Board  and  its  Audit  Committees,  and  our 

constructive relationship with HMRC. 

Our customer bills include an allowance to cover the corporation tax we expect to pay, like other operating costs. This 

allowance reflects the benefit of tax reliefs that are available to us, such as capital allowances on our investment in our 

assets, which helps keep customer bills down. 

Responsible procurement 

Our responsible approach to procurement is described on page 123 of this report.

NWL independent value for money survey - PR19NES_BES30 

We have not achieved our target.  

This customer survey is a bespoke measure which is reputational only.  

Our 2020 score of 8.3 out of 10 was the highest we’ve received in the last six years. This year the average satisfaction of 

customers that the services we provide represent good value for money decreased very slightly by 0.1 to 8.2 out of 10 

meaning we were just short of our PC.  

However, given the affordability challenges our customers are  facing, we are pleased to still achieve a high result and 

continue to promote the value of water through our Water’s Worth Saving campaign.  

In CCW’s Water Matters report 2021/22, we were pleased to score 83% in our NW region for satisfaction with value for 

money of sewerage services, which is significantly higher than the average water and sewerage company, and 81% for 

satisfaction with value for money of water services. 71% of participants agree charges are fair, again significantly higher 

than average. In our ESW region, 73% of participants were satisfied with the value for money of their water charges which 

was above the average score of 71%.  

Despite the recent bill increase, our bills (in NW region) are still the lowest water and sewerage bills in England.

Percentage of households in water poverty - PR19NES_BES06 

We have achieved this PC.  

This is a non-financial bespoke measure. We have an ambitious goal to eradicate water poverty and are delighted to have 

beaten our target this year to reduce water poverty further.  

This great result has been achieved despite the difficulties recent times have presented us with. Two years on from the 

economic impacts of the global coronavirus pandemic our customers are experiencing the highest inflation rate of the past 

30 years and significant increases to the cost of living in the form of higher energy, food, and fuel prices. The end to the 

£20  uplift  in  Universal  Credit  in  October  2021  hit  some  customers  with  hard-pressed  household  budgets,  driving  an 

increased reliance on foodbanks and difficult decisions about what to go without.  

Water and sewerage services should be affordable for all our customers, whatever their circumstances, and they should 

all have equal access to an unrivalled customer experience. In April 2022 we introduced our first water bill increase in three 

years, to secure important investments to networks, and reflecting the outcome of the recent CMA appeal process. Our 

charges remain lower in real and nominal terms, than in 2019/20, and our customers on average pay £1 a day for water 

and sewerage services. 

We remain focused on getting support to those who need it most and given the economic climate and expected investment 

demands at the next price review, expect to continue this focus into the future. Debt support agencies we’re in contact with 

are seeing increased contact from people struggling to pay their bills, which we expect to flow into increased applications 

for financial support.  

Here are some ways we have supported, and continue to support, our customers: 

•  During  2021/22,  the  number  of  customers  benefitting  from  financial  support  through  our  SupportPlus  tariff 

increased by 52.4% to 46,229. Our company-funded tariff also increased by 21.9% this year, which means we 

now have 10,803 customers benefitting from bill reductions of up to 50%. We’ve also seen a steady increase in 

our WaterSure numbers, which increased by 15.2% this year to 10,773. 

•  We can offer eligible customers discounts of up to 50%, either through our affordability tariffs or WaterSure. These 

tariffs are perfect if a customer’s total household income is less than £16,105, a member of the household receives

Pension  Credit,  or  their  household  income  doesn’t  cover  essential  bills.  By  the  end  of  March  2022,  we  were 

supporting 67,805 customers with a reduced bill. 

“Thank you so much this will make such a difference to us”. 

• 

If a customer’s income has reduced and they can’t afford their normal payment arrangements, we can offer a 

variety of flexible payment arrangements that are suitable for the individual. 

•  Supporting customers to switch to a water meter when this can save them money. Our instant, online calculator 

shows whether a water meter would reduce charges. We install meters for free and allow customers to track their 

water usage with an online account.  

"I've filled out the form and found that it was intuitive, asked questions that were easy to quantify and 

produced a report that was clear and easy to understand." 

• 

In  January  2022  we  relaunched  the  payment  break  service  (initially  launched  in  March  2020  for  Covid-19)  in 

response to the increased cost of living, to support customers experiencing new income shocks. Since the first 

lockdown, we’ve given nearly 8,200 customers a payment break. We are supporting customers at the end of their 

payment breaks with extended arrangements and spreading their remaining balance over the remainder of the 

billing  year.  78%  of  the  customers  whose  payment  break  has  completed  are  maintaining  their  plans  or  have 

already cleared their balance. We are offering support to the customers who are in arrears and by January 2021, 

412 customers were benefitting from a 50% reduction in their bills. 

• 

The Breathing Space legislation came into force on 4 May 2021 and gives someone in problem debt the right to 

legal protections from their creditors, usually for up to 60 days. To date we have placed holds on 1,530 customer 

accounts with a total debt value of £1.86M. While a customer is in Breathing Space, we communicate with them 

and their debt advisor about our SupportPlus options and ways we can help. 

•  Once a Breathing Space has ended (either after 60 days or earlier), 18% of our customers have made a payment, 

9% have moved to an insolvency route, 32% have agreed a payment arrangement and 14% have entered our 

affordability process. These trends have remained consistent. If a customer does not come out of Breathing Space 

with a solution, we proactively contact the customer to encourage them to talk to us for further support. 

•  We  put  protections  in  place  for  any  customer  who  has  been  in  a  Breathing  Space  to  make  sure  our  future 

communications recognise that they have experienced problem debt.  

• 

In 2021 we were the top water company for referrals to independent debt charity, StepChange. We made 2,848 

referrals, a 38% increase in our referrals rate. This was a fantastic achievement in a year where StepChange saw 

referral numbers drop across the charity. The Relationship Manager said:  

“I believe this is down to the time and effort you put in with your customer service teams and clearly shows how 

committed you are to helping clients in financial difficulty.”  

This work has been part-funded by the interest income earned on unutilised tax funding from the 2015-2020 price review, 

as we committed in our PR19 Business Plan, although the value of interest earned was very small due to the extremely 

low rates of interest receivable.

We are proud to be part of the core Development Group, led by Defra to create a single social tariff for England and Wales, 

and are playing an active role on several sub groups including economic modelling, operations, and communications. If 

implemented the tariff will make sure no-one has to spend more than 5% of their income after housing costs on water bills, 

something we have publicly supported as the first water company in the UK to commit to eradicating water poverty. 

Case study – Data sharing with the DWP to move customers out of water poverty  

In  March  2021,  we  were  an  early  adopter  of  data  sharing  with  the  Department  for  Work  and  Pensions  (DWP),  to  help 

identify customers in need of financial support. We securely share customer data with the DWP who matches it against its 

records to let us know if a customer is in receipt of certain benefits. This allows us to identify customers who may be eligible 

for our WaterSure and Pension Credit tariffs.  

This approach allows us to provide an amazing proactive service to our customers, applying discounts to their water bill 

and moving them out of water poverty, without the need for them to take time and effort applying to us. 

To date we have identified an additional 3,740 accounts we can place onto WaterSure and 9,240 onto Pension Credit. We 

have automatically applied these discounts and sent reduced bills. 

In March 2022 data matching was extended to include Universal Credit, this will increase the match rate for 2022/23.

Awareness of additional financial support - PR19NES_BES02a 

We have not achieved our target.  

This  bespoke  PC  measures  customers’  awareness  of  the  additional  financial  support  we  offer.  This  includes  both 

discounted bills and writing off customer arrears for eligible customers. We measure awareness in quarterly surveys with 

customers. Awareness of additional financial support dropped to 38%, lower than our target of 52%. 

We are disappointed with this result, especially as we have done a great deal of work in the last two years to help our 

customers who have found themselves in financially difficulty. We will continue to focus on supporting our customers who 

struggle to pay and see this as critical given current economic and financial challenges. Below, we share some of the ways 

we are working to improve performance in this area. 

•  We are integrating a sustained campaign across internal messaging, external communications, digital and social 

media, marketing, and stakeholder engagement acknowledging the wider affordability challenges being faced. 

We  brought  together  our  focus  during  Customer  Service  Week  (4-8  October  2021)  with  a  relaunch  of  ‘Water 

without the Worry’ where we focused on promoting the support services we offer and encouraged our customer 

service  colleagues  (‘Water  without  the  Worry’  Warriors)  to  use  a  specially  designed  social  media  tool  kit  to 

promote our services on their local social media groups. 

In  Q1  of  this  year  our  integrated  advertising  campaign  has  focused  on  the  message  ‘help  with  bills’  and  we’ve 

communicated a wide range of free support, especially for those who were unexpectedly affected by the pandemic and 

people who were already having financial difficulties. We continue to provide our customers with guidance on how we can 

help make sure their water bills are more affordable. 

•  When furlough ended on 30 September 2021, we emailed our customers to let them know about the financial 

support we have available, should they be struggling to pay their bills. The email detailed all the different ways 

we can help, and this achieved a fantastic 68% open rate with over 28K clicks to our websites. We’re promoting 

this message as much as possible across all our channels.  

•  Over Christmas 2021 we reached out to stakeholders asking them to share information about our financial support 

services  with  their  local  communities  and  partners.  We  also  provided  a  social  media  toolkit  with  examples  of 

Tweets, Facebook, and LinkedIn posts for them to use.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

•  Our  unmeasured  annual  bills,  which  were  delivered  during  February  and  March  2022,  made  use  of  both  the 

envelope and letter to raise awareness of our support and encourage engagement. The front of the envelope 

presented a clear message for customers who may be struggling to pay their bill. The back of the envelope asked 

customers if they receive Pension Credit or have a household income below £16,480 (the messages that receive 

highest click through rates in our email marketing and Google advertising) and invited them to scan a QR code 

or to visit our website to see if they qualified – a clear call to action. On the front page of the bill, we included a 

QR code to direct customers to our full digital solution for affordability and vulnerability. The back page of the bill 

includes information for customers who need help paying and gives details about our priority services. 

Case study – Reducing customer effort in partnership with Anglian Water 

We have been working with Anglian Water to identify how we can allow for a one stop application for tariff applications for 

our customers where we bill them for water, and Anglian Water bills them for sewerage.  

Anglian Water uses Policy in Practice’s benefit assessment tool to qualify customer applications for tariffs and we have 

now  agreed  for  a  joint  application  process  to  be  built  within  the  tool.  This  will  give  the  added  benefit  of  an  income 

maximisation check as part of the application.  

Policy  In  Practice  have  started  the  build,  and  once  live  customers  applying  either  with  us  or  via  Anglian  Water  will  be 

advised if they are eligible for either scheme. With their consent, their application will be sent to both companies to finalise 

the application.  

We also amended our data sharing agreement with Anglian to allow for them to share new WaterSure applications as the 

eligibility  criteria  is  consistent.  This  is  a  leading  approach  within  water  companies,  and  an  exciting  opportunity  to 

demonstrate collaborative working, as recognised by CCW, the voice for water customers. 

Steve Grebby, Policy Manager at CCW, said: “It’s great to see Essex & Suffolk Water working with Anglian Water to make 

it much easier for customers in our region to get the maximum help they are entitled to with their water and sewerage bills. 

The rising cost of living is putting intense pressure on low-income households which is why it’s vital water companies make 

it as simple as possible for customers to access help when they need it most.”

We continued to beat our target of 8.7 with a high score of 9.2. 

We  work  hard  to  make  sure  customers  receiving  financial  support  are  satisfied  with  the  services  they  receive  (via  a

Using  our  PSR  digital  twin  dashboard  which  details  internal  and  external  information  about  demographics,  sign-ups  to 

tariffs and PSR information to help us understand our customers better, we have been able to prioritise which segments 

to target who may need additional non-financial support. For example, segmenting pensioners, homes with young children, 

people living with health problems and households with an income below £16,105. From this information we’ve created a 

matrix of messaging by identifying with their needs rather than using generic messaging.    

We’ve created a suite of digital adverts using these messages which are promoted online on websites, social media and 

using keyword targeted on Google. We also continue our outdoor advertising for Just add Water that will support these 

messages for customers who are not online.  

We’ve also been using recent incidents and topical situations as a proactive opportunity to encourage customers to update 

their contact details with us, sign up for PSR, and promote online accounts (through email marketing and our social media 

channels). More than 2,700 people signed up to the Priority Services Register in one week following our communications

in one place. 

This drives a faster resolution and takes away effort and admin from the applicant, giving them more time to focus on what 

really matters. Settld users rate the service 4.9/5.

Priority services for customers in vulnerable circumstances - PR19NES_COM16 

This is a common, reputational PC. Its purpose is to ensure a minimum standard across all companies for the number of 

households registered on the Priority Service Register (PSR) and for PSR data checking.  

The PC has the following criteria: 

• 

The PSR reach: percentage of households that the company supplies with water and/or wastewater services that 

are registered on the company’s PSR. 

•  Actual contact: percentage of distinct households on the PSR that the company has contacted over a two-year 

period.  

•  Attempted contact: percentage of distinct households on the PSR that the company has attempted to contact over 

a two-year period. 

To achieve compliance with this PC, all the reach, attempted contact and actual contact targets must be achieved. 

Reach of Priority Services Register 

We have not achieved this PC.  

While we have not reached our target for the percentage of households on the PSR register, we have seen a significant 

increase in the number of customers who are benefitting from our PSR. More than 3.5% (69,255) of our households are 

now registered against our target of 7.6%. PSR membership figures include: communication (9,732), support with mobility 

and access restrictions (26,143), support with supply interruption (57,235), support with security (17,704) and support with 

other needs (27, 932).  

In February 2022 we made PSR registration easier for our customers by offering a full self-serve option on our website. 

We  offer  a  tick  box  list  of  all  the  services  we  offer  so  that  the  customer  can  self-select  the  services  which  are  most 

appropriate for them.

We  are  working  in  partnership  with  UK  Power  Networks  (UKPN),  Believe  Housing  and  Age  UK  North  Tyneside  to 

communicate the benefits of our PSR and to increase uptake. At the end of December 2021, we had 50,685 customers 

signed up to our Priority Services Register, an increase of 153% compared to December 2019. 

In December 2021 we began the first phase of a PSR data sharing programme with UKPN, the company which owns and 

maintains the electricity cables and lines in our Essex and Suffolk operating areas. We now receive around 10-15 new 

applications  a  day  from  UKPN.  We  are  manually  checking  and  updating  these  new  registrations  at  present,  with  the 

intention of moving towards full automation. Phase two, which will build the mechanism to extract PSR data from our CC&B 

system, to share with UKPN has started.  

We have approached Northern Power Grid (NPG), which is equivalent to UKPN in our Northern area; with the aim of setting 

up an equivalent data sharing programme for our Northumbrian Water customers.  

Believe Housing is one of the largest housing associations in the North East. Working in partnership we have added an 

additional 8,000 properties to our PSR. These are properties where Believe Housing has identified the occupiers as being 

vulnerable to an interruption to supply. We will approach other councils in our region to understand if this approach can be 

duplicated.  

We  know  that  our  older  customers  are  amongst  those  in  the  most  need  of  extra  support  when  we  have  an  extended 

interruption to supply. Working in partnership with Age UK North Tyneside, we are completing a trial where we have sent 

letters highlighting the benefits of PSR and the range of support services offered by Age UK to properties with occupiers 

aged over 80 years of age. This trial has brought 4,500 new  customers to our PSR. If extended this approach has the 

potential to add approximately 60,000 additional properties to the PSR.  

Sonya Roe, Business Development & Marketing Manager at Age UK North Tyneside, said: “We appreciate that working 

with trusted partners helps us to reach more customers and share messages about the services we can provide to them. 

“We were delighted to be approached by Northumbrian Water to help build confidence in the benefits of Priority Services 

Register and signpost to our own range of services. We very much look forward to working together in the future to bring 

benefit to our mutual customers”.

Review of Priority Services Register 

Actual contact 

Attempted contact 

We have achieved this PC.  

This  common  PC  verifies  customers’  needs  where  they  have been  on  the  PSR  for  more  than  two  years  and  we  have 

beaten both our actual and attempted contact targets this year.  

We are validating our PSR register in four main ways: 

•  When a customer who is already on our PSR contacts us the Customer Advisor receives an alert to verify their 

needs. 

•  As part of our proactive contact with customers, when we are  completing planned work, we review their PSR 

information.  

•  We are making outbound contacts to customers who were due to have their information validated who hadn’t 

contacted us directly. 

•  We  are  working  with  large  housing  associations  to  update  social  housing  properties  for  tenants  living  in 

accommodation reserved for anyone needing support.

Case study – Support for all (a cross-sector PSR hub)  

At our October 2021 Innovation Festival, we began exploring a solution to allow PSR data to be shared between different 

sectors.  In  February  2022  we  furthered  the  concept  by  hosting  more  than  60  participants  from  30  organisations  to 

collaborate on the design of a fully supported PSR journey for water and energy at a regional level.  

Our new solution means that customers only need to need to provide their details for it to be shared amongst the relevant 

utility companies. This gives customers a consistent experience with swift offers of assistance and benefits based on their 

individual needs. 

We have been awarded funding through the Catalyst Stream of Ofwat’s Water Breakthrough Challenge, which we will use 

to build and test a data hub to securely host and share PSR data. Our aspiration is to scale the hub both geographically 

and into other sectors, such as local authority and healthcare, into a national PSR platform.

British Standards Institute Award for Inclusive Services - PR19NES_BES23 

We have achieved this PC.  

This is a bespoke PC and is reputational only. Our target is to maintain this award consistently. This PC is designed to 

make sure we provide a fair, flexible service which can be used by all customers equally, regardless of their health, age, 

or personal circumstances. 

We’re  proud  to  have  maintained  BS  19477:  Inclusive  Service  Verification  this  year.  The  standard  assesses  whether 

inclusive services are fully accessible to all customers and that companies have the right business processes in place. 

This is the second year that we have completed the audit which reviews our approach to vulnerability and makes sure our 

services  are  inclusive  for  all  -  whatever  a  customer’s  circumstances.  During  the  assessments  BSI  reviewed  our 

documented  policies  and  procedures,  then  held  sessions  with  our  teams  to  see  how  we  operate  the  policies  and 

procedures on a day-to-day basis. The sessions include contact with all areas of the business, including call listening, a 

complaints review, our communications planning, how we manage events, debt recovery and affordability. 

With BSI alongside core expectations on delivery of service, they continually focus on seeing how we are continuing to 

develop our offering and learning from customer feedback. We’ve put an action plan in place to cover the non-conformity 

and opportunities highlighted, which will be completed this year to further enhance our website offering and how we improve 

the identification of triggers and risk factors that highlight our customers may be in vulnerable circumstances.  

We’re  always  reviewing  the  services  we  offer,  and  this  expert  assessment  provides  regular  external  scrutiny  of  our 

processes.

Percentage of void household properties - PR19NES_BES08 

We have achieved this PC.  

This is a bespoke measure, with financial incentives for both under and outperformance. Reducing the number of void 

properties,  which  are  occupied  but  not  billed,  leads  to  fairer  charges  between  customers  and  lower  bills  for  customers 

already being billed. This year we’ve beaten our PC and earned a financial reward of £1.333M for doing so. 

Billing all customers in a timely and accurate way has always been our focus. The introduction of this new measure to 

incentivise water companies to minimise the number of void properties led us to look closer at our process for identifying 

‘Occupiers’ who have failed to register.  

Last year we worked closely with TransUnion to improve the way that we proactively use credit reference data to identify 

properties that are occupied yet not billed. We now have our new process embedded, which alongside the automation we 

have  developed  to  deal  with  returned  post  and  auto-bill  these  newly  identified  occupiers,  has  made  the  whole  empty 

property routine much more efficient. 

We still need to employ the more traditional empty property processes where the credit data approach isn’t successful, but 

it  does  mean  that  we  are  better  able  to  target  our  property  visits.  This  year  we  have  been  working  with  several  local 

authorities and housing associations to share information on their tenants who may not yet have registered for billing, these 

arrangements help tenants by reducing back billing and creating debt and help us to further reduce our unbilled properties.  

In future years we expect to see improvements by using data from our smart metering programme to help identify when 

customers have moved out without telling us or where they have started to use a supply that we have registered as empty.  

We can see some of this data starting to come through. The number of smart meters is still relatively low so this will have 

limited impact on numbers at this time.

Gap sites - PR19NES_BES07 

We have not achieved this PC.  

The aim of our bespoke gap site PC is to reduce the risk of sites or properties receiving water and/or wastewater services 

that  are  unknown  to  us  and  are  not  being  billed.  Reducing  the  number  of  these  gap  sites,  which  are  also  potentially 

occupied, leads to fairer charges between customers and lower bills for customers already paying. This PC is reputational, 

so no penalty or reward is payable.  

The number of gap sites cannot be measured directly as they are unknown to us. The only way to assess gap site risk is 

by comparing our property data with third party information to look for differences. We set a PC to match most of our non-

household  premises  database  (contained  within  our  corporate  Customer  Contact  and  Billing  system)  with  the 

Government’s Valuation Office Agency (VOA) business premises ratings list – aiming to achieve a match of 87.1% by the 

end of 2021/22. 

Not all the active premises in our database are eligible to be on the VOA ratings list and those that are, don’t always have 

a  VOA  reference  number.  Local  Authorities  introducing  new  or  revised  numbering  structures  can  cause  unmatched 

premises, as can simple transcription errors or mistakes when data was entered into our system. 

The number of matched combined household and non-household premises in our operating region is unknown as we have 

been unable to implement our matching project due to continued issues because of Covid-19 and its impact on resource 

availability. We are at the early stages of reviewing the matching processes and will begin the manual matching process 

on 1 September. We continue with the automated matching process and our records are updated daily.   

We remain confident of meeting our five-year target and hope to accelerate our matched rates as we complete our aligned 

unique property reference number (UPRN) matching processes over the next year. 

The matched premise percentage has been derived by taking new additions on the VOA ratings list (4,247) less deletions 

(6,333), cross referenced against the final figure submitted last year (155,756), which provides assurance on the accuracy 

of our match rate of 64.3%.

Risk of severe restrictions in a drought - PR19NES_COM10 

We have achieved this PC.  

The overall metric is the percentage of our population at risk of experiencing severe restrictions in a 1-in-200-year drought, 

on average, over 25 years. The metric tracks water company implementation of Our PR19 Water Resources Management 

Plan (WRMP19) supply and demand schemes, to reduce the percentage of customers at risk of severe drought restrictions.  

We report a result of 0% of population at risk for this metric, meeting our PC, reflecting progress to date with implementing 

our  WRMP19  schemes.  Our  WRMP19  demonstrated  that  we have  100%  security  of  supply  in  all  our  Water  Resource 

Zones (WRZs), across the full 40-year planning horizon. We also demonstrated resilience to a drought with a return period

of 1 in 200 years in all our WRZs, with 0% of our customers at risk from severe supply restrictions. We therefore did not 

need to promote any supply schemes in our WRMP19 but did include demand management schemes.  

Delivery of our smart water metering enhancement programme - PR19NES_BES26  

We have not achieved our target.  

This is a bespoke, penalty-only PC to incentivise delivery and return funding to customers if we fail to deliver the programme 

in full by March 2025. The PC specifically measures the percentage delivered of our smart metering programme. This is 

limited to installing new smart meters and replacing existing basic meters with smart meters. Only household meters can 

be counted for this PC, and only once for each household in the five-year period. New developer installs are also discounted 

from the PC despite advanced metering infrastructure (AMI) meters being installed at these properties. 

We’re committed to rolling out smart water meters for our customers with the overall goal that all our meters will be fully 

smart by 2035. While we made significant progress with the mobilisation of our smart programme in the last year, we did 

not achieve our PC for 2021/22. 

We had a tough start throughout 2020/21 as our meter installations were impacted by procurement delays, the suspension 

of metering activity such as fitting and replacing meters in response to government guidance, and a reduction in the number 

of customers applying for a meter. Our meter installations were further impacted in 2021/22 by supply chain delays caused 

by the global chip shortage, inability to recruit additional installation resource in a challenging labour market and a continued 

reduction in the number of customers applying for a meter.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

To make up for this, in May 2021 we re-orientated our smart water meter enhancement programme to become a significant 

transformation programme recognising the positive impact it will deliver for our customers and for the organisation.  

Continued Covid social distancing restrictions meant some customers were reluctant to allow our employees inside their 

homes, for some this persists even after Covid restrictions have been lifted. We believe the reduction in demand for meters 

is also due to concerns about increased water consumption with more people working from home, and the reduction in 

unmeasured bills in our Final Determination from Ofwat, because saving money on water bills is one of the main drivers 

for our customers to apply for a meter. 

However, we remain confident that we will deliver 100% of the programme by March 2025 and our expected delivery profile 

is shown in the chart above.  

We continue to offer our customers free water meter installations, on request. However, we started introducing AMI meters 

in 2021. Our first AMI meter installations took place in May 2021 in Dagenham, Essex, where commissioning an Arqiva 

base  station  enabled  us  to  install  approximately  8,000  smart  meters  connected  to  the  Arqiva  Flexnet  communications 

network. 

During 2021/22, a total of 44,141 meters were installed across our three operating regions (North East, Essex, and Suffolk). 

These were a mix of automated meter reading (AMR) (6,808) and AMI capable meters (37,456). This split was due to the 

need  to  install  our  remaining  inventory  of  AMR  meters  that  we  held  in  our  warehouses  while  we  ramped  up  our  AMI 

inventory. The AMR meters and AMI meters installed at new domestic developments do not satisfy our ODI as a result 

only 27,877 of the AMI installs contribute to the ODI.  

All domestic meter installs are now AMI capable with the possibility to connect them to a smart network and allow them to 

operate  as  true  AMI  meters  in  the  future.  In  2022  we  will  tender  for  a  smart  communications  network  provider  (CSP) 

covering all three of our supply regions which will allow us to offer smart metering to all our customers who want it and 

start systematic replacement of AMR meters at end of life or proactively where we can see an opportunity to reduce PCC 

or leakage.  

We recognise the positive impact smart metering can have on delivery of a more proactive customer experience, supporting 

reduction in PCC and both customer and network side leakage.

Case study: Raising the bar with the IoC 

As part of our drive to make sure our customers always receive great customer service and experiences, we’ve worked 

closely  with  the  Institute  of  Customer  Service  (IoC)  to  gain  accreditation  for  our  Unrivalled  Customer  Contact  (UCC) 

training.  

Following the success of the training across our Contact Centre, we’re working with our Smart Metering programme to 

deliver  UCC  to  smart  field  teams.   Sharing  tools  and  tips  using  real  on  the  job  examples,  we’re  successfully  bringing 

unrivalled customer experience to life for our field teams. 

The training is in two parts. Classroom-based training brings to life the huge impact our field teams have in making our 

customers feel important and valued. In the days and weeks following the training attendees complete their UCC workbook 

and our trainers provide ongoing coaching and development in real time to embed learning, celebrate success and identify 

new areas for improvement. 

The field teams are clearly embracing their training and feeding back improvements to continuously make our customers 

experiences better. One example is the introduction of the monetary value of a quantity of water to our leaflets. While we 

were providing a visual picture of what a quantity of water looked like, our customers had advised our field teams that they 

wanted to relate this to money. This is now being introduced to our leaflets, alongside water efficiency messaging that 

shows how saving water can also save energy, save the customer money, and help the environment. 

Feedback  and  engagement  throughout  this  training  has  been  high  and  we  are  already  seeing  great  improvements  in 

customer feedback.

Delivery of our water resilience enhancement programme - PR19NES_BES24 

This programme comprises several schemes which seek to improve the resilience of our water supply system which are 

due for completion by March 2025. These schemes include Springwell reservoir, and upgrades to the Tees pipeline in our 

northern operating area, and the Abberton to Hanningfield pipeline and Suffolk resilience enhancements in our Essex and 

Suffolk area.  

The aftermath of the pandemic along with recent global events and the resulting supply chain and inflationary pressures 

continue to place significant challenges on our capital delivery programmes, and we are currently reviewing the impact this 

will have on delivery of these schemes by the March 2025, and the extent to which we can mitigate this.  

We remain committed to delivering these schemes for customers. 

Delivery of our lead enhancement programme - PR19NES_BES25 

We have not achieved this PC.  

This programme is supported by a bespoke, penalty-only PC to incentivise delivery and return funding to customers if we 

fail to deliver the programme in full by March 2025, alongside a reputational target in each year of the period against which 

we can track progress. We have not achieved our target this year, however, we remain confident that we will deliver 100% 

of the programme by March 2025.  

As a priority, we want to protect those most vulnerable to the effects of lead in drinking water by focusing on lead pipe 

replacement in buildings frequented by children (our Vulnerable Groups scheme, which covers educational and community 

establishments).  

In addition to protecting our most vulnerable communities, our lead pipe replacement programme prioritises areas at the 

highest risk to lead exposure (our Hot Spots scheme). These schemes are spread across our three geographic supply 

areas so all our customers will benefit.

To mitigate the risk of lead in drinking water at the tap, the programme goes beyond replacing our lead communication 

pipe by replacing the customer’s lead supply pipe to inside their homes. The success of replacement therefore requires 

individual property owner’s consent.  

Our lead replacement programme was impacted throughout 2020/21 by Covid-19. There were two main aspects of this. 

Firstly, the impact that the government restrictions had on our supply chain and their people being furloughed as a result, 

and secondly, our awareness that customers would be reluctant to engage in a programme that involved work inside their 

homes.  

In  year  1,  we  focused  on  developing  the  delivery  strategy,  including  setting  up  the  commercial  framework,  and  on 

implementing  the  model  for  delivering  and  reporting  on  our  lead  enhancement  commitments.  Although,  some  lead 

replacement was able to start in 2021, concerns for the pandemic were still understandably high and it wasn’t until January 

2022  that  we  were  able  to  move  forward  with  more  assurance  within  the  circumstances.  We  are  gaining  a  greater 

acceptance from customers to work on their property, and as the pace of replacement is accelerating, we remain confident 

that we will meet our lead enhancement targets by 31 March 2025.  

Delivery of our wastewater resilience enhancement programme - PR19NES_BES27 

We have achieved this PC.  

This bespoke, penalty-only PC tracks the delivery of our wastewater resilience enhancement programme. This programme 

is focused on delivering investment at 141 sewage treatment works (STW) and sewage pumping stations (SPS) to increase 

the resilience of our wastewater network and mitigate disruption to customers.  

We achieved 39 outputs in 2021/22 (ahead of the target), which included a variety of measures to mitigate flood risk or 

improve recovery in the event of power failure.   

134 site visits have been completed. They involved a survey of the assets at each site, together with a review of flood 

mapping  data  and  historical  operational  experience.  The  outcome  of  these  surveys  is  to  develop  cost  beneficial

investments solutions for each site. Reports which prescribe draft scopes and outline designs are already complete for 106 

sites.    

Our focus for 2022/23 will be to complete the remaining survey reports and to have delivered outcomes for at least 70 sites 

as we strive to deliver increased resilience of our network.   

A pipeline of work and a programme schedule is being developed to assist in the planning and delivery of outputs to 2025 

and we have appointed an independent technical auditor to evidence the deliverables achieved.    

Delivery of our Howdon sewage treatment works (STW) enhancement - PR19NES_BES29 

We have achieved this PC.  

Howdon  is  one  of  our  largest  STWs.  This  scheme  seeks  to  improve  the  sites  resilience  by  building  in  an  element  of 

redundancy to address single points of failure currently present at the site.  

To support this aim, four key assets have been identified as requiring an upgrade: the primary effluent pumping station 

(PEPS), the Southbank pumping station (SBPS) and both associated rising mains.  

This programme is supported by a bespoke, penalty-only PC to incentivise delivery and return funding to customers if we 

fail to deliver the scheme by March 2025. We remain on target to deliver the resilience elements of this scheme within 

these timescales. 

With our lead technical consultant, Wood Group, we have developed a conceptual design for the upgrades including a 

review of all available technologies. We plan to locate the new PEPS rising main in a more suitable location and in March 

2022, we purchased land adjacent to the existing Howdon site to facilitate this major upgrade. Due to the additional benefit 

of reducing spillages from Howdon STW, the resilience scope has been increased to include additional management of 

storm flows. This should mean fewer occasions where there is a need to discharge effluent that has not gone through the 

treatment works in times of rainfall or snowmelt, reducing the number of discharges into the environment. We anticipate 

this will reduce spillages by 50%. We know our customers want us to greatly reduce  spillages and we are setting new 

aspirational targets for our approach to rives and coasts in our long-term vision for 2050.  

Work is underway to develop the design further so that a robust set of tender documents can be produced. Construction 

work is scheduled to commence in spring 2023, in line with our original plan. All new assets will be commissioned and 

brought into service in early 2025.  

The  project  has  a  further  objective  to  increase  the  permitted  dry  weather  flow,  due  to  the  anticipated  increase  in  the 

population in the catchment (estimated to be 150,000 population equivalent) in the next 25-30 years. The delivery of this 

additional scope is aligned to the programme for the expected population growth, which is continuously under review so 

that business risk is fully managed. Delivery of this growth scope will be phased to complete by early 2027.

We have achieved this PC.  

This programme aims to deliver multiple benefits by enhancing our cyber security function and supporting compliance with 

the  Network  and  Information  Systems  (NIS)  Directive.  Our  PC  was  to  deliver  the  first  40.4%  of  the  programme  during 

2021/22 and this has been achieved.  

We continue to monitor the increasing cyber threat landscape to make sure our investment is focused on the areas that 

have the greatest impact on protecting our business. Keeping up with advancements in technological and human cyber 

capability, particularly from well-funded foreign state threat actors is both challenging and expensive so we make sure our 

investments are allocated to the most appropriate areas.  

Several cyber security procurements and enhancement have been made during 2021/22 and others are currently in flight. 

We continue to develop our security posture in line with our continuous improvement strategy to make sure technical and 

human advances by malicious threat actors are mitigated appropriately and keep our people and our customers safe.

Delivery of our Drainage and Wastewater Management Plan (DWMP) - PR19NES_BES32 

We have achieved this PC.  

For the first time in 2023, we are publishing a Drainage & Wastewater Management Plan (DWMP) to identify how we will 

extend, improve, and maintain a robust and resilient drainage and wastewater system considering the pressures of climate 

change, population growth and growing customer expectations. 

Publication of our DWMP is supported by a bespoke, reputational-only PC, performance against which will be assessed in 

2023. We are currently on track to deliver this. 

During 2021/22, we identified significant, resource heavy tasks required linked to latest guidance on climate change, storm 

overflows and customer consultation. We completed Problem Characterisation and Option Development & Appraisal on 

the  250  drainage  areas  that  progressed  through  Baseline  Risk  and  Vulnerability  Assessments  and  developed  our 

Programme  Appraisal  methodology  that  considers  Defra  Consultation  on  the  Government’s  Storm  Overflow  Discharge 

Reduction Plan (published on 31 March 2022). 

We  have  continued  to  attend  national  DWMP  groups  to  make  sure  we  are  up  to  date  with  regulator  and  industry 

expectations as well as quarterly meetings with the Strategic Planning Group (SPG) to present updates, methodologies 

and seek guidance on our approach. The SPG is made up of relevant external stakeholders who provide challenge. Our 

continued engagement with customers to inform them about the issues relevant to our DWMP have included a quarterly -

newsletter that is posted on our website, and we have also sought feedback via our DWMP customer portal. We’ve also 

worked hard to plan in assurance with our Internal Audit team to make sure the DWMP aligns with our Water Resource 

Management Plan (WRMP). 

As  well  as  drafting  our  customer  focused,  technical,  non-technical  and  overall  DWMP  reports,  we  also  published  our 

Strategic Environmental Assessment (SEA) approach for consultation and received three responses; our draft SEA is now 

being developed and reviewed. 

The  DWMP  sets  out  how  we  intend  to  extend,  improve,  and  maintain  a  robust  and  resilient  drainage  and  wastewater 

system and takes a long-term view, setting out a planning period that is appropriate to the risks we face with a minimum 

period of 25 years. As a result of this, DWMPs will inform our Business Plan submissions for the next price review in 2024 

and beyond. For subsequent planning periods, DWMPs will become embedded within our planning processes as business 

as usual.  

The framework provides the basis for more collaborative and integrated planning with and alongside organisations that 

have responsibilities relating to drainage, flooding and protection of the environment. DWMP analysis will give us a more 

strategic  view  of  expenditure  requirements  in  service  areas  (such  as  sewer  flooding,  pollution  incidents)  which  are 

forecasted to deteriorate due to the impact of growth, climate change and urban creep. From the DWMP we will create

This is a common PC. Our PC requires us to deliver a reduction of 1.8% for 2021/22 against a baseline taken in 2019/20, 

on a three-year rolling average basis.  

The  Covid-19  pandemic  has  had  a  pronounced  effect  on  PCC  (which  reflects  household  water  consumption  only,  as 

opposed to business use), through increased water use for hygiene requirements and a substantive shift to home working. 

Social distancing restrictions have also limited our ability to implement water efficiency measures in customer homes. 

As a result, PCC has increased by 4.7% against the 2019/20 baseline.  

The aim for our programme of activities was to deliver a 1% reduction in PCC, as well as addressing the shortfall from 

2020/21. We have not achieved our target.   

We continued to monitor the impact of Covid-19 on household consumption and have sought to disaggregate the impact 

of Covid from other variables that influence PCC. We have worked with the Met Office to model demand within our regions 

in two phases, showing that: 

•  PCC for our operating areas overall increased by 5% between April and August 2020. 63% of this was due to an 

increase in base  demand from  normal, and  37% was due to an increase in weather dependent demand from 

normal. 

•  Between April and September 2021, demand in all three of our operating regions stayed higher than 2019 (pre-

Covid).  The  weather  dependent  demand  seen  from  people  being  at  home  using  water  in  the  garden  has 

significantly  reduced  in  this  period  compared  to  2020/21.  From  this  it  can  be  concluded  that  Covid-19  alone 

impacted total demand and PCC over and above the effects of the weather.  

The first half of 2021/22 saw the continuation of lockdowns and meant our people continued to review, adapt, and develop 

innovative approaches and a new water efficiency strategy for the remainder of the 2020-25 period. As we moved into the 

second half of the year and out of Covid-related restrictions, we were able to initiate various new approaches alongside 

returning to our tried and tested interventions. We remain committed to a long-term target on reducing the water taken 

from the environment by delivering effective campaigns and interventions to reduce PCC to 118 litres per person per day 

by 2040 and 110 by 2050.   

Highlights of our new water efficiency strategy include: 

•  Our new home water and energy saving retrofit programme, effectively targeting the highest users of water. 

•  Video calls to survey customer’s homes and offer a continuation of our home water and energy saving retrofit 

programme. 

•  An online water and energy calculator allowing customers to produce personalised reports with tailored water and 

energy saving solutions. 

•  A  highly  engaging  online  school  education  programme  providing  teachers  with  interactive,  curriculum  linked 

resources for KS2 children.  

•  Gold Sponsorship of the 2022 Waterwise Conference. 

•  Active and leading involvement in two national water efficiency behaviour change campaigns  - Water’s Worth 

Saving and Pledge21.

Integrating water efficiency as a core customer journey in our smart metering programme. 

In addition, we have completed several phases of customer research to understand changes in work location, staycations, 

water use now and in the future. Customers told us that working from home has increased and they were using more or 

much more water. Frequent surveys have allowed us to understand the trends and changes over time. 

We will continue to carry out research and data analysis throughout 2020-25 to make sure we have a clear picture of what’s 

changing and how the pandemic continues to impact PCC. 

Ofwat has acknowledged the impact of the pandemic on  PCC  and has agreed to defer the application of any financial 

incentives to 2024/25, at which point it expects to conduct a comprehensive review to ascertain appropriate incentives. 

The PCC reporting methodology is broken down into reporting components and then into elements. We can confirm that 

that the reporting methodology used to provide these figures is consistent with a ‘green’ (I.e. compliant) assessment against 

each component. 

Case study – Tackling leaky loos  

Leaking toilets are the single biggest waste of water in the home, equivalent to an extra two people’s water use and occur 

in 5-8% of homes. For our customers this would mean between 110,000 and 176,000 homes with a leaking toilet right now 

- wasting around 23 million litres of water every day - which far outweighs the water saving benefit of the dual flush toilet.  

Because  of  this,  tackling  leaky  loos  forms  a  key  component  of  our  water  efficiency  strategy.  It’s  an  area  that  we  can 

demonstrate success over the past year with the greatest number of repairs in a single year and being shortlisted in the 

Water Industry Awards 2022.  

The programme is also great news for customers. In addition to the provision of an essential plumbing repair service free 

of charge, we are also supporting customers to reduce their bills. The repair of a single leaking toilet in a metered home 

could save the occupants hundreds of pounds each year.   

For years, we have offered a free repair service for leaky loos to all our customers. We have concentrated our work on 

helping customers identify leaky loos and promoting our free service in tandem with actual repairs.  

With the culprit being a leaky drop valve system (button flush) that can often trickle a minimal rate for years before becoming 

obvious, unsurprisingly a leaky loo may not always be particularly obvious to customers. In turn, we’ve developed a range 

of marketing and communications activities – ranging from free leak detection packs to Facebook advertising, to targeting 

new housing estates, to door-to-door customer engagement – which in turn has seen the number of leaking toilets repaired 

increase from 1,167 in 2020/21 to 2,348 in 2021/22.  

Collectively, this has saved a huge 504,820 litres every day.  

Tim Wagstaff, our Water Efficiency Manager, said: “We are doing what other companies are not, which is tackle one of the 

biggest areas of water wastage in the home; leaking toilets. We are working collaboratively as a sector with the bathroom 

industry to put a permanent solution in place. For now, our leaky loo programme is a cost-effective way of significantly 

reducing PCC now while supporting our customers to avoid a large bill for a plumber at a time when household costs are 

rising.”

As we move into 2022/23, we are progressing lots of exciting and innovative approaches to help us help more customers. 

We have developed a TV advert that will soon go ‘live’, and we will continue to identify new approaches to targeting homes 

that have a higher propensity to have a leaky loo. 

Unplanned outage - PR19NES_COM13 

We have achieved this PC.  

This is common, penalty-only measure, which is used to assess the health of our assets for our water abstraction and 

water  treatment  activities.  It  is  designed  to  make  sure  water  companies  appropriately  maintain  and  improve  the  asset 

health  of  their  non-infrastructure  or  above-ground  water  assets  for  the  benefit  of  current  and  future  generations  and 

demonstrate their commitment to asset stewardship responsibilities.  

Ofwat set us the very ambitious target of having only 2.34% of unplanned outages by the end of 2025. We have once again 

improved performance reporting 4.57% across the company beating our target of 5.36%. 

The new Water Treatment Works (WTW) in Berwick has had a positive impact on unplanned outage and investment made 

in Horsley and Warkworth have also reduced overall unplanned outage. We continue to inform Ofwat of any unplanned or 

planned situations when we’re unable to meet PWPC because of any asset failures or the inability to treat water to required 

standards. In addition, we continue to improve our processes and simplify the data entry process for operations. Internal 

engagement  through  regular  meetings  and  outage  reviews  means  our  people  have  a  clear  awareness  of  the  need  to 

accurately record outages. Our improvement plans remain centred on proactive maintenance regimes, continued operator 

asset care and delivery of future investment to our water treatment assets. 

The unplanned outage reporting methodology is broken down into reporting components and then into elements. We can 

confirm  that  that  the  reporting  methodology  used  to  provide  these  figures  is  consistent  with  a  ‘green’  (I.e.  compliant) 

assessment against each component.

Interruptions to supply and the impact of Storm Arwen  

Storm Arwen hit the North East of England over 26 and 27 November 2021 and was one of the most powerful and damaging 

winter storms in a decade. There was widespread and sustained loss of power across the region and a major incident was 

declared.  The  loss  of  power  had  a  significant  consequential  impact  on  provision  of  water  to  our  customers,  primarily 

because of loss of power to our assets and associated loss of communications. 

We have three PCs to assess the extent to which customers water supplies were interrupted during the year. 

•  Customer interruptions between 1 and 3 hours duration, measured in average mm:ss across the year. 

•  Customer interruptions of greater than 3 hours duration, measured in average mm:ss across the year. 

•  A count of properties interrupted for greater than 12 hours.  

We have conducted a thorough and independent review into the effectiveness of our response to the storm, to make sure 

we can learn any lessons and improve our response to any future events.  

The overall findings from this review were that our response was robust, quickly mobilised and effectively organised. It also 

concluded that we went beyond our duty in organising alternative water supplies and made sure customers on our Priority 

Services Register received the support they required.  

In the context of what was a very challenging and exceptional event to respond to, the review also identified a small number 

of areas where we could have been more robust - especially in relation to provision of back-up power - and had this been 

the case then we could have lessened the impact on customers.  

The  terms  attached  to  these  three  PCs  allow  us  to  make  a  representation  to  Ofwat  for  an  exemption,  where  a  civil 

emergency  has  occurred,  as  is  the  case  for  Storm  Arwen.  On  this  basis  we  believe  we  would  be  entitled  to  seek  an 

exemption  for  the  entire  impact  of  the  storm  on  our  performance.  However,  given  the  outcome  of  our  review,  we  are 

proposing to accept a small proportion of the performance impact in relation to those areas where our response could have 

been more robust .2 

Below we provide two sets of figures: 

1.  What our performance would be if the impact of Storm Arwen is included in full (Ofwat has asked us to provide 

these figures). 

2.  What our performance would be, if in line with our representation, we accept a small portion of the impact. It is 

these figures which we believe to be the fairest reflection of our performance for the year. 

2the portion of the ODI we are proposing to accept is based on the difference between the total ODI impact calculated based on all Arwen related interruptions being 

included in their entirety, and what the total Arwen related impact would have been if our response had been more robust. i.e., we are proposing to accept the ODI impact 

relating to the extent to which shortfalls in our response extended customer outages.

Interruptions to supply between one and three hours - PR19NES_BES14 

The figure below includes the full impact of Storm Arwen. This exceptional weather event added 0m:24s to this measure.  

The figure below includes a small proportion of the impact of Storm Arwen, consistent with the representation we have 

made to Ofwat. We believe to be the fairest reflection of our performance for the year. 

We performed strongly across the year and have achieved this PC under all three scenarios described above.  

This  is  one  of  our  two  supply  interruption  bespoke  measures  for  2021-25.  We  used  three  years  of  data  from  2018/19 

through  to  2020/21  to  establish  a  ‘baseline’  level  of  performance  from  which  we  can  measure  our  performance  as  a 

percentage change. 

For this measure, all interruptions between one hour and two hours 59 minutes are added up to give the total time that 

customer  supplies  were  lost  across  our  supply  area.  We  then  divide  this  total  time  by  the  total  number  of  connected 

properties  we  serve.  This  gives  an  average  time  in  minutes  and  seconds  that  we  have  interrupted  each  customer  for 

between  one  and  three  hours.  The  Baseline  average  of  the  last  three  years  is  08:17mm:ss.  If  Ofwat  accepts  our 

representation, we expect to outturn at 87.9% compared to baseline (outturn at 07:17mm:ss). This performance will result 

in a reward of £0.604M. 

An  interruption  to  the  water  supply  can  either  occur  on  a  planned  basis  when  we  carry  out  network  maintenance,  or 

unexpectedly when a burst, third party damage or other failures occur in the network. We recognise that interruptions to 

the water supply can cause our customers real inconvenience - especially when they’re unexpected and we cannot warn 

customers in advance.  

Our performance in this area is dependent on which water mains fail and where they are located, and we have found that 

one event can have a large impact on our figures. For example, if we have been able to restore supply quicker (under three 

hours) due to better network connectivity or being closer to a depot to swiftly collect the maintaining supplies trailer and

deploy  an  overland  rider,  then  this  measure  will  be  seen  to  be  improving.  Whereas  the  >3hour  measure  may  suffer 

adversely consequently.  

We shall be looking at further initiatives to drive improvements to performance, as we will continue to share learnings and 

carry out training to increase everyone’s awareness of keeping an interruption as short as possible without any implications 

to health and safety and / or the environment.

Water supply interruptions greater than three hours - PR19NES_COM04 

The figure below includes the full impact of Storm Arwen. This exceptional weather event added an additional 6m:57s. 

The figure below includes a small proportion of the impact of Storm Arwen, consistent with the representation we have 

made to Ofwat. We believe to be the fairest reflection of our performance for the year. 

We performed strongly across the year. If Ofwat accepts our representation, we will achieve our PC.   

This is a common measure designed to incentivise companies to minimise the number and duration of supply interruptions. 

For this measure, all interruptions of three hours or longer are added up to give the total time that customer supplies were 

lost across our supply area. We then divide this total time by the total number of connected properties we serve. This gives 

an average time in minutes and seconds that we have interrupted each customer for three hours or longer. Reducing the 

number and duration of interruption events improves the reliability of supply and reduces negative social and public health 

impacts  on  customers.  If  Ofwat  accepts  our  representation,  we  expect  to  outturn  at  05:51  mm:ss  against  a  PC  of 

06:08mm:ss. Excluding Storm Arwen we would have achieved our target. 

An  interruption  to  the  water  supply  can  either  occur  on  a  planned  basis  when  we  carry  out  network  maintenance,  or 

unexpectedly when a burst, third party damage or other failures occur in the network. We recognise that interruptions to 

the water supply can cause our customers real inconvenience - especially when they’re unexpected and we cannot warn 

customers in advance.  

Our performance in this area is dependent on which water mains fail and where they are located, and we have found that 

one event can have a large impact on our figures. One burst in Teesside in April 2021 added a massive 41 seconds to the 

results  this  year.  This  strategic  main  burst  in  Longbank,  Middlesbrough,  affected  circa  7,000  properties  with  a  supply 

interruption  (many  more  with  low  pressure)  and  our  people  worked  hard  to  make  sure  water  was  restored  as  quickly 

possible so no property exceeded 12 hours. Many properties were restored in under three hours through means of rezoning 

15 July 2022

FOR YEAR ENDED 31 MARCH 2022 

water from another source, however, many more properties were then affected for approximately three to six hours as it 

took a while longer to further rezone water and to recharge the remaining areas. 

We continue to learn from the events we have had by holding weekly reviews to share what went well and where we could 

have done things differently, sometimes changing processes to prevent similar occurrences. We endeavour to improve our 

response times to all reports of nil supply, understand when to escalate an event, and acknowledge our forward thinking, 

such  as  when  restoring  supplies  through  alternative  methods  (before  the  repair  is  completed).  Our  focused  approach 

means that all teams involved know to keep supply interruptions as short as possible.    

We continue to carry out Post Interruption Reviews for events over three hours that affected more than 100 properties. 

The aim of these meetings is to understand and record what  we could do better and share any learning to reduce the 

likelihood of a similar event occurring again and allow others to gain knowledge from other’s experiences. 

We have also begun developing a MOWBI, which is a mobile pumped water storage unit that enables some properties 

restored temporarily. These are particularly useful in those events where a property requires a more complicated repair or 

there is a health and safety reason. We anticipate this will mean some customers may experience a shorter interruption in 

the future, even while the permanent solution is still ongoing.

Interruptions to supply greater than 12 hours - PR19NES_BES09 

The  figure  below  includes  the  full  impact  of  Storm  Arwen.  This  exceptional  weather  event  added  an  additional  5536 

properties. 

The figure below includes a small proportion of the impact of Storm Arwen, consistent with the representation we have 

made to Ofwat. We believe to be the fairest reflection of our performance for the year. 

This is our second bespoke supply interruptions measure for 2020-25 where we report the number of properties which are 

affected by a Water Supply Interruption for 12 hours or longer. This is a very stretching target to meet over the next few 

years as it could only take one large event that could result in losing the ability to achieve our performance commitment 

for this measure. If Ofwat accepts our representation we will outturn behind our PC at 917 properties which will result in a 

penalty of £1.4M. 

We continue to drive good performance through our focused approach of restoring customer supplies where interruptions 

have been seen to be lengthy or complicated.  Much emphasis has been placed on providing alternative supplies such as 

overland riders or redirecting water from elsewhere and in some cases escalation to event management has also played 

its  part  in  this  year’s  success.  This  year  we  have  developed  a  MOWBI  which  is  a  mobile  storage  until  which  can  be 

transported  to  single  properties  experiencing  a  loss  of  supply  which  temporarily  restores  supply  to  the  property  at  a 

sufficient pressure until the permanent resolution is in place.  

We continue to carry out Post Interruption Reviews for events over 12 hours with the aim to understand what we could do 

better and share any learning’s to reduce the likelihood of a similar event occurring again.

Leakage Northumbrian Water (NW) - PR19NES_COM05 

We have not achieved this PC.  

This  is  a  common  measure  with  several  industry-wide  reporting  methodology  changes  for  2020-25  which  aim  to  help 

companies calculate leakage more consistently.  

Leakage  from  the  water  network  is  measured  in  Megalitres  (millions  of  litres)  lost  per  day.  Leakage  levels  fluctuate 

throughout the year as the weather changes, and we report the average daily level at the end of the year. Our PC is the 

percentage  reduction  of  three-year  average  leakage  against  our  2019/20  baseline.  We  are  still  seeing  the  effects  of 

2020/21 on the three-year average figures as it was a tough period for a number of reasons - customer reported leaks 

were much lower during lockdown, and we were also hit by extreme weather with a significant freeze thaw weather event 

which caused lots of mains bursts. Despite this we still performed better than average in 2020/21 compared to other water 

companies but there is more to do to hit our targets.  

For 2020/21 we were required to deliver a reduction of 3%. Northumbrian Water (NW) has seen leakage average 130.5 

megalitres per day (Ml/d) in 2021/22. This gives three-year rolling average performance of 134.7Ml/d (an   reduction of 

0.1%  against  the  baseline),  whereas  the  level  required  to  achieve  our  target  was  130.8Ml/d.  This  incurs  a  penalty  of 

£683,000.  

After a difficult winter in 2020/21, we started in a poor position and have worked throughout the year to reduce the number 

of outstanding leaks and to minimise the average run times with increased resources, which is reflected in our visible leak 

repairs performance, something customers tell us is very important to them. Leakage is more difficult to calculate during 

the summer months, due to increased (and sometimes unpredictable) demand levels and the number of leaks that break 

out  because  of  the  ground  drying  out.  We  saw  significant  supply/demand  issues  in  the  Tyneside  zone  throughout  the 

summer, and resources were diverted to this area to maintain supplies to our customers. To better understand this problem, 

we have invested in fast logging monitors so we can get more accurate estimates of our customer consumption, and we 

have carried out some flow balances on the strategic network to see exactly where the water demand has increased.   

There  have  been  several  innovative  interventions  employed  alongside  the  standard  Active  Leakage  Control  processes 

throughout the year as well. 6,000km of mains have been surveyed via satellite to highlight potential points of interest;

Digital twins of the network have been developed to tackle problematic District Metered Areas by identifying specific areas 

of focus for our leakage technicians; acoustic logging trials have been carried out with multiple suppliers and further studies 

have been done to review our plumbing losses value. 

We have made a good reduction this year in annual performance but recognise it wasn’t enough to achieve the three year 

average target. We are providing additional investment in the NW region to help us get back on track with meeting our 

targets by 2025. This includes additional Leakage Technicians, scaling up the digital twin project, continuing to improve 

data quality for all water balance components and maximising the benefit of existing pressure management schemes. 

The leakage reporting methodology is broken down into reporting components and then into elements. We can confirm 

that  that  the  leakage  reporting  methodology  used  to  provide  these  figures  is  consistent  with  a  ‘green’  (I.e.  compliant) 

assessment for all but one of the components, and we can confirm that the one component assessed as Amber has no 

material impact on our reported performance. 

Leakage Essex & Suffolk Water (ESW) - PR19NES_COM06 

We have not achieved this PC.  

This  is  a  common  measure  with  several  industry-wide  reporting  methodology  changes  for  2020-25  which  aim  to  help 

companies calculate leakage more consistently. Leakage from the water network is measured in Megalitres (millions of 

litres) lost per day. Leakage levels fluctuate throughout the year as the weather changes, and we report the average daily 

level  at  the  end  of  the  year.  Our  PC  is  the  percentage  reduction  of  three-year  average  leakage  against  our  2019/20 

baseline. We are still seeing the effects of 2020/21 on the three-year average figures as it was a tough period for a number 

of reasons - customer reported leaks were much lower during lockdown, and we were also hit by extreme weather with a 

significant freeze thaw weather event which caused lots of mains bursts. Despite this we still performed better strongly in 

2020/21  compared  to  other  water  companies  with  Essex  &  Suffolk  Water  (ESW)  having  some  of  the  lowest  levels  of 

leakage in the country.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

For 2020/21 we were required to deliver a reduction of 3.7%. ESW has seen leakage average 59.3 megalitres per day 

(Ml/d) in 2021/22. This gives three-year rolling average performance is 63.1Ml/d (a reduction of 3.2%) whereas the level 

required to achieve our target was 62.8Ml/d. This incurs a penalty of £54,000.  

After a difficult winter in 2020/21, we started in a poor position and have worked throughout the year to reduce the number 

of outstanding leaks and to minimise the average run times with increased resources, which is reflected in our visible leak 

repairs performance, something customers tell us is very important to them. Leakage is more difficult to calculate during 

the summer months, due to increased (and sometimes unpredictable) demand levels and the number of leaks that break 

out because of the ground drying out. To better understand this problem, we have invested in fast logging monitors so we 

can get more accurate estimates of our customer consumption.   

There  have  been  several  innovative  interventions  employed  alongside  the  standard  Active  Leakage  Control  processes 

throughout the year as well. 2,000km of mains in Suffolk have been surveyed via satellite to highlight potential points of 

interest;  digital  twins  of  the  network  have  been  developed  to  tackle  problematic  District  Metered  Areas  by  identifying 

specific areas of focus for our leakage technicians; acoustic logging trials have been carried out with multiple suppliers and 

further studies have been done to review our plumbing losses value. 

We have made a good reduction this year in the annual performance and despite missing our PC, we remain one of the 

industry leading companies in terms of leakage per property. Our focus is now on delivering the interventions that will get 

us back on track for next year. These include scaling up the digital twin project, continuing to improve data quality for all 

water balance components and maximising the efficiency of our existing leakage technicians. 

The leakage reporting methodology is broken down into reporting components and then into elements. We can confirm 

that  that  the  leakage  reporting  methodology  used  to  provide  these  figures  is  consistent  with  a  ‘green’  (I.e.  compliant) 

assessment against each component. 

Case study - Jellyfish; innovative trial for smart metering 

We are working with internet experts B4T and Welsh Water in trialling an innovation in smart water metering which could 

help customers avoid large bills. 

B4T’s Jellyfish device clips on to existing water meters, which are typically in underground chambers and do not easily 

connect to 4G, 5G or Wi-Fi. Jellyfish gets around this problem by connecting wirelessly over 0G, a low-power technology 

from Sigfox. 

Data is analysed by B4T’s software to identify and prioritise leakage which helps to prevent damage to people’s homes – 

and  wallets.  Preliminary  results  showed  the  device  was  96%  reliable,  even  from  the  most  challenging  of  underground 

meter boxes. 

We have helped to fund the project – which is taking place in Cardiff and Tywyn, north Wales – and will analyse additional 

benefits for our own smart water metering programme. The Jellyfish device, a unique alternative to installing smart water 

meters,  is  being  utilised  in  Welsh  Water’s  ‘Cartref’  programme,  which  aims  to  reduce  instances  of  leaks  in  customers’ 

pipes.

Gary  Adams,  Head  of  our  Smart  Programme,  said:  “This  timely  collaboration  with  Welsh  Water  and  B4T  presents  an 

opportunity  to  further  our  understanding  of  new  and  innovative  solutions  in  the  smart  metering  space  and  proactive 

identification of leakage. 

“Working closely together we can learn quickly and reduce the need to replicate costly large-scale trials so we can deliver 

value to our customers.” 

Alex Barter, managing director of B4T, added: “B4T are on a mission to redefine smart water metering. 

“Jellyfish  was  designed  from  a  blank  sheet  of  paper  to  meet  the  unique  demands  of  the  UK  water  sector  and  our 

environmentally-charged business principles.” 

Hampshire-based B4T are the leading internet-of-things experts for the water industry. 

Visible leak repair time (days) - PR19NES_BES04 

We have achieved this PC.  

This is a bespoke PC to incentivise us to reduce the time it takes to repair customer-reported visible leaks. This will reduce 

the amount of water wasted through leaks, something our customers tell us is very important to them and demonstrates 

that we are responding.  

We’re delighted with our final performance of 6.7 days, against a target of eight days and an improvement on last year. 

This translates into an ODI reward of £0.339M. 

We’ve been promoting our leak portal to encourage customers to report leaks online making it quicker and easier for them 

to report. We also made improvements in how contacts were categorised in corporate applications midway through the 

year, with monthly performance consistently bettering the target. Ongoing communication in how to prioritise customer-

reported visible leaks has been paramount, as well as their link to the Leakage ODI.  

We introduced a new work pattern for our repair crews which includes Saturdays, with most of the work completed on a 

Saturday being visible leaks.

We are currently working with a data science consultant to improve prioritisation, report visualisation and publicity of how 

the target reduces further through 2020-25, and how we can continue to attain target while identifying more efficient means 

of repairs. 

Mains repairs (was bursts) - PR19NES_COM12 

We have achieved this PC.  

This is a common PC and is measured per 1,000km of the entire water main network conveying treated water around the 

distribution  point  (excluding  communication  and  supply  pipes).  Proactive  (found  because  of  active 

leakage 

control/detection by the company) and reactive (customer reported) repairs are reported separately. 

We measure the number of mains bursts by counting the repairs we make to water mains each year. This year we repaired 

110.9 mains bursts per 1,000km, which is well below our PC of 137.1. We will once again receive a reward – this year it is 

£1.411M. 

Since  2019/20  our  burst  performance  from  April  through  to  December  has  been  very  consistent  in  terms  of  bursts 

accumulated  over  this  period.  It  was  the  winter  weather  conditions  experienced  during  January,  February,  and  March, 

which has had the biggest influence on our final year end performance. In contract to the 2020/21 reporting year, this winter 

was particularly benign across both the North East and Essex and Suffolk. 

In 2020/21 we replaced approximately 16km of distribution main in the north and 7km of distribution main in ESW. We 

have updated our predictive burst modelling capabilities, with refreshed models taking into consideration many new factors 

such as the proximity of a pipe to a bus route or water courses. Our continued programme of employee training on calm 

network operations, has proved to be effective in reducing the number of bursts we create whilst operating the network.

Abstraction Incentive Mechanism (AIM) - PR19NES_BES18 

We have achieved this PC.  

Abstraction  Incentive  Mechanism  (AIM)  AIM  is  a  common,  financially  incentivised  measure.  Our  PC  in  this  area  (the 

number of days beyond the collar level) is zero and once again, it was not triggered this year.  

We report the number of days in  our WRMP Annual Review which we submit on 30 June. The Annual Review is then 

approved each year by the Environment Agency. 

Our one AIM scheme site at Ormesby Broad, Norfolk, is designed to protect its valuable designated habitats and ecology. 

This year’s summer (May to September inclusive) rainfall was around the long-term average once again. We managed 

broad water levels to remain well above the AIM trigger point and performance was as expected, given the average rainfall 

over the summer period.

OUTCOME 8: Our drinking water is clean, clear and tastes good  

AMBITIOUS GOAL: Promote confidence in our drinking water so that nine out of ten of our

•  Water quality compliance (CRI) – common  

•  Event Risk Index (ERI) – bespoke 

•  Discoloured water contacts – bespoke  

•  Satisfaction with taste and odour of tap water – bespoke 

Water quality Compliance Risk Assessment (CRI) - PR19NES_COM03 

We have not achieved this PC.  

CRI  is  a  common,  penalty-only,  calendar  year  PC  using  a  risk-based  monitoring  methodology,  which  assesses  water 

quality compliance against our statutory obligations.  

Our CRI was 6.36 (to 2 decimal places) against a PC level of 0, with penalties applying for performance higher than 2.0, 

incurring a penalty of £6.078M. This is marginal improvement to our overall score in 2020. For 2021 most of our CRI score 

is derived from compliance failures in our Essex and Suffolk operational area whilst in 2020 it was primarily the North East. 

When a failure occurs at an asset or in a supply area which is subject to an agreed programme of work with the DWI, the 

DWI’s compliance assessment will increase the associated CRI score. In 2021, this effect increased the CRI total by 2.8 

units. 

The  biggest  impact  on  CRI  for  2021  was  a  bacteriological  failure  from  a  water  treatment  works  in  Essex  area,  which 

accounted for 2.453 units. This represents more than 30% of the final figure and this single failure would exceed the penalty 

deadband itself in any year. There was no definitive cause for the bacteriological failure at Hanningfield following a detailed 

root  and  branch  investigation.  A  few  minor  issues  were  observed,  and  these  have  been  rectified.  We  now  have  one 

outstanding action left which is the inspection of the treated water reservoir; this is planned for later this year. A sampling

FOR YEAR ENDED 31 MARCH 2022 

campaign at the time of the failure demonstrated that the result was confined to the treatment works and had no impact on 

customer supplies or public health. 

More than 85% of the sample failures recorded in 2021 were at customers’ taps at the point use. Over half of these results 

were  because  of  internal  plumbing  or  the  property  supply  pipe  and  therefore  did  not  attract  any  CRI  points.  In  these 

circumstances, we work closely with the customer to understand the issue and determine a root cause. Support for the 

customer  can  take  several  forms,  including  the  issue  of  precautionary  advice  and  bottled  water  while  investigations 

continue, education and awareness on tap hygiene and cross contamination in the home, and the replacement of lead 

communication pipes supplying a property where the risk is shown to be elevated. Our aim is to make sure customers 

retain a high level of trust in the tap water we provide. 

We are seeing the benefits of the enhanced service reservoir maintenance programme and recorded just three service 

reservoir (SR) failures in 2021, a large improvement to previous years. These were all in the Essex region. In the North 

East where most of the scrutiny has previously been, compliance was 100% for the year. 

In  the  last  12  months,  we  have  also  completed  the  full  replacement  of  a  treatment  site  in  Berwick  (Murton),  which  will 

provide more reliable supplies and meet future drinking water standards. This will be supplemented in the next year with 

the completion of the new Horsley works feeding large proportions of Tyneside, this new works is partially in supply. The 

replacement of three sites in Northumberland is to be completed in 2022 along with the completion of the installation of UV 

treatment at two works supplying the Durham and Wearside areas. 

We are continuing with the enhanced programme of treated water storage tank inspections to mitigate some of the risks 

identified at these sites, alongside a risk review of treatment processes. We’re disappointed to not hit our high standards 

in this area as we are committed to achieving industry-leading levels of CRI and are delivering our long-term plans to reach 

this, as well as working closely with the Drinking Water Inspectorate (DWI). We’ve accelerated and increased funding in 

our base capital programme as part of a transformation plan with the DWI.  

We are continuing to prioritise our efforts around water treatment where CRI risk is highest, and areas of focus include 

filter  media  refurbishment,  carbon  regeneration,  and  water  quality  minor  works  activities  such  as  on-line  monitoring 

capability to increase resilience and control of the treatment processes.  

The journey of water from treatment through to customer tap is important, and in our networks, we are continuing with the 

enhanced service reservoir maintenance programme, inspecting and (where applicable) repairing a higher number of tanks 

per annum to maintain the integrity of these assets and minimise any water quality risks. We are using a combination of 

physical assessment and technologies such as Remote Operating Vehicles (ROVs).  

We are also trialling smart network innovation to allow real time operational decisions to be made on the quality of water 

being supplied through our networks and so improve the customer experience.

Case study: Water industry skills champion Aleck Bruce  

One of our Training and Competence Specialists has been named the Water Industry’s Skills Champion for 2021 after 

helping to shape training that will support thousands of people across the country and make sure key services continue to 

be delivered by highly trained teams. 

Aleck Bruce, from Darlington, received the accolade from the Institute of Water, an organisation which supports the careers 

of people within the industry, and Energy & Utility Skills, which backs skills development across the wider sector. 

He was recognised for having played a key role in developing a wide range of industry training standards, including those 

that shape Apprenticeships and safety procedures. 

Aleck chaired the UK committee which implemented the e-version of the industry’s National Water Hygiene Card and was 

part of the Industry Hygiene Best Practice Group, which guides the work of water companies and suppliers. 

He has also chaired a group involved in producing the new Apprenticeship standards for water production and network 

operation for the Institute for Apprenticeships and Technical Education. These will help to make sure those striving to work 

in the industry, or who are using Apprenticeships to update their skills, receive training that meets the highest and most up 

to date standards. 

Additionally, Aleck chairs the industry-wide Water Assurance Assessment Panel, and regularly sits on the apprentice final 

decision panels as an industry expert. 

He said: “It’s vital that the people who work in our sector are trained to the best possible standards, whether they have just 

started their careers or have been in the industry for 30 years. 

“It’s a privilege to play such an active role in helping to shape training that will not only enable this, but which will help keep 

people safe while delivering the essential services we provide. 

“I’m honoured to have been recognised by the Institute of Water and EU Skills in this way.” 

Erin Price, our Head of Talent and Training, added: “We’re really proud of the work Aleck does, not only within Northumbrian 

Water but for the industry. It’s vital work that goes on behind the  scenes but makes such an impact on the successful 

delivery of water and wastewater services across the whole of the UK, and the award is really well deserved.”

Event Risk Index (ERI) - PR19NES_BES13 

We have not achieved this PC.  

This is a bespoke, penalty-only, calendar year measure and this PC incentivises us to promote a proactive approach to 

risk mitigation of water quality events, including understanding the impact of events on customers.  

Events are assessed by the DWI, and the assessment considers the seriousness of an event, our response, the population 

impacted, and the duration. During 2021, 37 events were notified to the DWI for assessment, resulting in 289.699 units 

against  a  PC  of  224  units,  incurring  a  penalty  of  £0.072M.  This  represents  a  deterioration  from  last  year  and  we  are 

disappointed we have not reduced the occurrence and/or impact of water quality events on our customers.  

The outcome in 2021 was influenced by two events which together generated 216.7 units. A communications failure on a 

telemetry station at Mosswood, one of our major water treatment works (WTW) in the North East, resulted in sub-optimal 

treatment for a short duration. This was a high-potential situation which is why it attained such a high ERI score, however 

the quick response by the site team meant that customers supplied by this site did not experience any impact to service.  

The second event related to Storm Arwen in November 2021, one of the most powerful and damaging storms in a decade. 

The  Met  Office  issued  a  red  weather  warning  and  while  the  storm  was  notable  both  for  its  extreme  wind  speeds  and 

freezing temperatures, many sources point out that what made the storm particularly rare and destructive was the direction 

of the wind. Significant power disruptions were experienced across Northumberland and parts of County Durham because 

of the extreme wind speeds, and this interrupted supplies over several days.  

The  situation  was  declared  a  civil  emergency  under  The  Civil  Contingencies  Act  (2004).  We  commissioned  Jacobs  to 

prepare  a  report  into  our  storm  preparedness  and  response.  Jacobs’s  findings  concluded  that  our  extreme  event 

preparedness was up to industry standard and that we went above and beyond to attend to our customers in the aftermath 

of the storm.  

We’re committed to improving on ERI performance and investing in our assets. 

We received positive feedback to our response, particularly around alternative water provision, customer communications 

and resilience.

“We have our water back. Please pass on our thanks to your technicians for all their hard work.”  

“Well done to the guys who worked tirelessly to reinstate our supply – give them a good Christmas bonus.”  

“Thank you for the excellent work you had to do to get us all linked again to mains water. On behalf of Scremerston stand 

up and take a bow.”  

“Mrs X says she really appreciates getting through to speak to someone. She says that whatever is happening, she can 

always speak to someone here and that has been very rare over the storm period. 

Discoloured water contacts - PR19NES_BES11 

We have achieved this PC.  

This is a bespoke calendar year measure that reflects the number of times we’ve been contacted by customers due to the 

appearance of their tap water not being clear, per 10,000 population. The appearance measure covers seven contact types 

including discolouration (brown/black/orange and blue/green/pink), aerated water, particles, and general conditions.  

Our PC this year was 9.75, which we’ve beaten, earning a reward of £1.168M. We’ve continued to perform better than our 

PC for the seventh year in a row.  

Our plan continues to focus on appearance: discoloured water – brown, orange, or black, which is our major contributor of 

contacts to this measure. Very occasionally, and for a short time, customers’ tap water may appear discoloured. This is 

caused by the disturbance of harmless material in our water supply network, possibly caused by a burst, leak or third-party 

activity. We are continuing to progress with our programmes of work agreed with the DWI to improve the number of trunk 

mains in which flow can be automatically raised with less risk of disturbing mains material and causing discolouration in 

downstream supply areas. Continuing to flush smaller sized pipes closer to customers is happening on a prioritised basis 

as well as investigations into how to improve the other contact types such as water coloured white due to aeration. We’ll 

also look for innovations that can cleanse parts of the network which cannot be managed with our current techniques.

We’ve  increased  the  number  of  text  messaging  alerts  to  inform  customers  that  we  are  aware  of  an  issue  and  are 

investigating  the  potential  cause.  We’ve  also  continued  with  employee  training,  to  make  sure  we  are  using  the  correct 

operational techniques, which we know helps to manage the number of contacts we receive while we work on the network.  

Taste and smell contacts - PR19NES_BES12 

We have achieved this PC.  

This bespoke measure reflects the number of times we’ve been contacted by customers to report perceptive issues with 

the taste or smell of their tap water. We want our customers to be satisfied with the taste and smell of our tap water.  

We received 847 taste and smell contacts in 2021. This level of performance is better than the upper quartile (top 25%) 

threshold,  and  better  than  our  stringent  PC  of  960  contacts.  An  outperformance  reward  of  approximately  £0.158M  is 

payable  for  this  measure.  The  drinking  water  we  supply  is  very  high  quality,  but  occasionally  some  of  our  customers 

perceive different tastes or odours. This could be due to:  

• 

The use of chlorine to maintain good hygiene in our water supply network.  

•  A change in where a customer’s water comes from, or how it is treated.  

• 

Issues with a customer’s own plumbing inside their home.  

•  A change in a customer’s perception.  

Around 40% of customer taste and smell contacts are recorded as chlorine based. We have been carefully controlling the 

level of chlorine in the water, balancing the needs of water safety and water acceptability. Customer engagement has also 

identified  that  change  causes  concern  for  customers  and  can  therefore  trigger  contact.  Water  supplies  for  most  areas 

routinely come from the same source. However, to carry out asset maintenance, or in response to reactive issues like a 

burst pipe, water to an area can be re-zoned through a different route or come from a different source treatment works. It 

may also be necessary for us to change the source of supply in drier weather to protect resources and preserve stocks.

Internal sewer flooding - PR19NES_COM08 

We have not achieved this PC.  

This is a common measure with financial incentives associated with under and out performance.  

Internal sewer flooding is one of the worst performance failures our customers can experience. We have maintained the 

internal sewer flooding performance we reported last year which showed a substantial reduction of 48% in 20/21.  

Our target was to improve further but 2021/22 proved much wetter than normal, with major storms and floods such as 

Storms Arwen and Dudley. This wet weather had major impacts across our region and meant that our performance is not 

quite where we expected it to be, despite delivering all the activities in our flooding improvement plan to schedule. 

We have estimated the impact of the wet weather has led to 20% more incidents featuring in our 2021/22 performance 

compared  to  expectation.  Even  though  this  was  a  challenging  year,  we  know  this  isn't  good  enough.  We  have 

underperformed against our PC and in accordance with our structure for this measure, an underperformance payment of 

£630,000 will be paid. We have apologised to the affected customers and have worked hard to mitigate the damage by

clearing blockages as quickly as possible, or by repairing the pipe/defect if it is relatively straightforward and cost effective 

to do so  - particularly where there is a risk of repeat flooding. For hydraulic incapacity (of the sewer network) we will carry 

out investigations to confirm the cause and identify a solution. This is then prioritised along with all our investments. We 

have paid affected customers Guaranteed Standards Scheme (GSS) payments in line with our statutory obligations.   

We’re working to make sure this is minimised in future, and that we can cope with increasingly wet weather conditions. We 

are continuing our monthly review of our tactical plans to identify the initiatives that are working well and those we could 

improve. This has already helped us plan our approach for 2022/23 and will inform the decisions we need to make for the 

next  three  years  so  that  we  can  achieve  our  future  targets.  While  we  already  perform  relatively  well  against  the 

recommendations recently laid out in Ofwat and CCW’s joint sewer flooding research report, we recognise that areas for 

improvement exist. 

We will also be publishing our DWMP in June 2022 and this will help inform our plans for future investment up to 2060 

around sewer flooding and other performance areas, such as pollution and storm overflow discharges. This investment will 

help us to reduce sewer flooding in future.

Repeat sewer flooding - PR19NES_BES17  

We have significantly outperformed our PC.  

In line with our ambition to reduce sewer flooding in the home as a result of our assets and operation, our bespoke PC for 

repeat sewer flooding (properties which have flooded internally more than once in the last five years) remains an important 

performance measure for us and for our customers.  

This result is down to several factors including increasing rigour through our manager-led investigations of all potential 

repeat  flooding  incidents  that  understand  cause,  effect,  and  accurate  categorisation.  Our  broader  flooding  tactical  plan 

continues to drive down the risk of internal, and therefore repeat flooding incidents, through tackling customer misuse, 

improving the network in known flooding hotspots and delivering more property level protection schemes. Collectively these 

activities drive down the risk of internal and repeat sewer flooding accounting for the 76% reduction we have achieved in 

repeats since 2019/2020.  

In accordance with our incentive structure for this measure, we’ve earned an outperformance payment of £1.157M.

External sewer flooding - PR19NES_BES16 

We have not achieved this PC.  

This is a bespoke measure with financial incentive.  

We  continue  to  improve  our  external  sewer  flooding  performance,  reducing  our  reported  numbers  by  a  further  12% 

compared  to  last  year’s  performance.  This  further  reduction  in  external  sewer  flooding  incidents  means  that  we  have 

reduced our overall number of incidents by 28% since we first implemented our sewer flooding reduction plan. 

The wet weather we experienced also impacted our expected external sewer flooding performance meaning that despite 

this further improvement our performance was also not where we anticipated that it would be for 2021/22.   

The extreme weather event on 5 October 2021 led to a total of 258 contacts being received on that day, compared with a 

typical  average  of  around  28  contacts.  This  is  the  fourth  highest  daily  contact  we  have  received  since  28  June  2012 

(Thunder Thursday). As part of our response to this event, we set up a dedicated project team to assist with investigating 

all these potential flooding incidents. 

As  a  result  of  our  performance,  we  have  underperformed  against  our  PC  and  in  accordance  with  our  structure  for  this 

measure, an underperformance payment of £1.649M will be paid. 

In response to the increased number of external flooding incidents associated with wet weather, we have expanded our 

sewer flooding studies to investigate chronic repeat external incidents, as well as reviewing appropriate measures that we 

could provide for properties through our existing Property Level Protection programme. We have paid affected customers 

Guaranteed Standards Scheme (GSS) payments in line with our statutory obligations.

Risk of sewer flooding in a storm - PR19NES_COM11 

We have achieved this PC.  

This is a common measure with no financial incentive.  

As  result  of  the  supporting  hydraulic  modelling  work  that  we  carried  out  as  part  of  our  Drainage  and  Wastewater 

Management  Plan  (DWMP),  we  achieved  our  2024/25  performance  commitment  for  this  measure  last  year,  four  years 

ahead of schedule. As our first DWMP is nearing completion and will be published in draft by the end of June 2022, this 

modelling work has now been completed and there has been no further opportunity to reduce our reported number further.   

Our 2021/22 performance therefore remains at 16.11% in accordance with the number we published in our last APR.   

This measure is reputational only and therefore no outperformance reward has been earned.   

As we develop future DWMPs into and beyond the next regulatory reporting period, we will seek to lead the industry by 

further outperforming any future performance commitment in line with ambitious goal to eradicate sewer flooding in the 

home as a result of our assets and operations.

Sewer blockages - PR19NES_BES15 

We have not achieved this PC.  

Blockages are a significant contributing factor to sewer flooding which is why we have this bespoke measure in place.  

We have made a reduction in the number of sewer blockages we reported compared to last year, but despite this we have 

not achieved our PC. In accordance with our structure for this measure, we’ve incurred an underperformance penalty of 

£0.883M. 

Analysis we have carried out shows our improvement plan initiatives such as our industry leading Bin the Wipe campaign 

are having a significant impact – we have now engaged more than 75,000 households and this has led to a 45% reduction 

in blockages in the areas we have visited.  

However, there is more we can do to increase our reach across the region, which is why we are now targeting an additional 

100,000 households in prioritised locations by sending an additional 100,000 households letters explaining about the work 

we are doing to reduce sewer blockages, and the impact that flushing wipes down the toilet has on our network and on the 

environment.  Our plan is that Bin the Wipe will engage 270,000 households directly by December 2022.   

Our  FOG  (fats,  oils  and  grease)  advisors  are  doing  a  great  job  educating  food  service  establishments  on  grease 

management  and  best  practice  to  prevent  FOG  from  entering  our  network.  They  are  also  targeting  repeat  domestic 

offenders which has uncovered blockages forming in the network, allowing us to clear them before they cause an issue.   

We  are  also  improving  our  training,  rigour,  and  governance  that  we  have  in  place  for  our  blockage  investigations  and 

reporting and continue to review and analyse the data trends that we observe. We have begun to embed continued training 

and  learning  on  clearing  and  removing  blockage  material  from  the  system  to  prevent  blockages  forming  downstream, 

increased awareness and investigation to identify possible secondary blockages within the vicinity of the originally reported 

incident, and further assessment and recording of blockages first reported as odour contacts.  

Using a third party to provide an independent assessment of our performance data will help us to make sure we effectively 

and efficiently manage sewer blockages and continue to have the right interventions in place to help reduce the numbers 

that we report.

Case study – Bin the wipe  

Our war on wipes continues to help protect homes and the environment from pollution. 

Our industry leading Bin The Wipe campaign aims to help people understand the problems caused by sewer blockages 

containing wipes that have been flushed down the toilet. 

By  helping  people  understand  that  this  can  cause  waste  to  back  up  into  people’s  homes,  or  be  forced  out  into  the 

environment, we hope to encourage people to put wipes into the bin, not down the loo. 

When we first launched Bin The Wipe at the start of 2020, we trialled a different initiative in parts of Redcar, giving away 

bins. More than 50% of homes do not have bins in their bathrooms, and the aim was to make better flushing habits as easy 

as possible. 

While this pilot was a success, resulting in a 43% reduction in the number of blockages caused by wipes in the area, a trial 

of the letters and tracking took place in Stockton, with even greater success, and this is now being rolled out in flushing 

hot spots across the North East. 

Over the last year we’ve targeted hot spot areas across the North East including around 4,500 homes in Redcar and 6,000 

homes in Billingham.  

Customers  receive  letters  explaining  the  issues,  and  how  a  team  will  be  monitoring  the  area’s  sewers,  finding  flushed 

wipes, and tracking back up the network to the properties from which they were flushed. 

As the team close in on streets, or even individual homes from which wipes are being flushed, further letters and doorstep 

conversations will reinforce the need for people to stop using their toilets as bins. 

Simon Cyhanko, our Head of Wastewater Networks, said: “Wipes that have been flushed down the toilet are the number 

one contributor to blockages in our sewers. We find them in more than 60% of the blockages we clear. 

“We know not everybody in the area flushes wipes, and we thank those who dispose of them properly. However, those 

who do are putting not just their own homes, but those of the people who live near them, at risk of sewer flooding.

Sewer collapses (per 10,000km sewer) - PR19NES_COM14 

We have achieved this PC.  

This is a common measure with an associated penalty.   

We are continuing to reduce our sewer collapse number and have outperformed our PC once again, reducing our reported 

sewer collapse number by a further 10% compared to last years’ performance.  

We carried out specific training within our operational teams to embed the learning and best practice we have identified 

throughout  the  year.  We’re  also  seeing  several  sewer  collapses  avoided  through  proactive  investigations,  for  example 

those identified as part of our find and fix activities associated with our Flooding Other Causes Programme.  

In  accordance  with  our  incentive  structure  this  measure  is  penalty  only  and  therefore  we  do  not  earn  a  reward  for  our 

outperformance.

FOR YEAR ENDED 31 MARCH 2022 

Leading in innovation  

Innovation is at the heart of everything we do as it’s one of our five core values. We are working hard to enable innovation 

right across the business so we can deliver the ambitious goals set out in our  Business Plan and to make sure we are 

leading, in both the water sector, and beyond. This year, in addition to building on the strong foundations we have laid with 

regards to fostering an innovation culture within the business, we have also focused our efforts externally; on bringing in 

external funding to grow our innovation capacity and growing our external partnerships. 

Innovation culture 

Innovation has replaced creativity as one of our five company values and we are enabling more of our employees to play 

an  active  role  in  innovation.  Our  innovation  ambassadors  are  at  the  core  of  this  process,  enabling  and  spreading  an 

innovative culture across our business and driving the implementation of new ideas so innovation becomes business as 

usual. This group has grown from 14 in 2018 to over 80 people in 2021 spanning all aspects of the business and across 

all levels. We also engage monthly via our Innovation Connect newsletter and invite external organisations that excel in 

innovation  to  a  quarterly  Innovation  Connect  virtual  call.  Alongside  our  core  skills  training  programme  and  the  NWG 

Innovation University which offers bite-sized training covering all the core elements of innovation, we are running a Creative 

Leadership  programme  with  the  Royal  College  of  Arts  to  extend  the  thinking  of  35  of  our  key  leaders  across  the 

organisation. In addition, innovation has been a key part of our last two Leadership Conferences to emphasise the role our 

leadership teams have in growing the innovation culture across the business.  

Innovation Festival  

The Innovation Festival has now been successfully run five times in three different formats always bringing newness and 

generating genuine business impact. The festivals are an important element of our innovation programme and are key to 

generating ideas given their outward facing nature that creates and builds meaningful partnerships. These events are now 

widely  anticipated  and  attract  industry-wide  participants  nationally  and  from  across  the  globe.  This  year,  the  global 

pandemic had loosened its grip slightly, so we opted to run our first hybrid event. This was our biggest festival with 54 

activities taking place, 38 sprints and six of which were hybrid in format (both physical and virtual). The festival attracted 

62 sponsors from 22 sectors, 800 organisations with participants from over 40 countries. In addition, Sydney Water ran its 

first Innovation Festival at the same time using the same blueprint as ours. We passed on our expertise to help them run 

their event, further reinforcing our leadership in innovation globally. We also had eight sprints that had global hubs including 

US, India, Ireland, and Australia. The hybrid nature of the event meant it was very inclusive and accessible and attracted 

a more diverse audience than we would be able to work with in our normal business activities. The equivalent professional 

services value of this contribution is estimated to be between five and six million pounds.  

Since our first Festival we have taken more than 200 ideas back into the business and put more than £1.5M back into the 

local economy, demonstrating our convening power to bring others into our regions. In 2021 we reached more people than 

ever  across  social  media  channels  (LinkedIn,  Twitter,  and  Facebook),  building  up  a  strong  innovation  community  with 

thought leadership and impactful content that had a social reach of  over 2.3M. The festival output projects cover many 

aspects  of  the  business,  including  the  Tipping  Point  tool  that  has  the  potential  to  save  many  millions  in  our  asset 

programmes. 2021 also saw the fruition of the National Underground Asset Register (NUAR) as the tender was secured 

by Atkins. This idea was one of the first to come out of our inaugural festival and was the first years’ worth of work in a 

week in 2018 which demonstrates what is possible from the festival and brings to life our very strong cross sector convening 

power.

Innovation fund  

During 2021 there have been three rounds of the Ofwat Innovation Fund. This competition is set up to fund projects that 

are beyond business as usual and encourages collaboration across the water sector and beyond. This competition has 

great potential for us as it will enable us to fund and run innovation projects that would normally be beyond our capacity, 

both in terms of costs and personnel. Having been successful in the first round in February 2021 we secured funding for 

two  projects,  the  UK  Water  Sector  Centre  of  Excellence  (Spring)  and  a  sector-first  project  to  turn  ammonia  into  green 

hydrogen  fuel,  collaborating  with  Organics,  Wood  Group,  and  Warwick  and  Cranfield  Universities.  In  round  two,  we 

submitted five bids into the Catalyst round (one stage process for projects between £100K-£1M).  We picked up three 

winning bids out of the 13 funded, securing £1.79M, which was approximately a third of the fund allocated (£5.2M). The 

projects were: SuPR Loofah, a sector first phosphorus removal technology, Support for All, a platform to help vulnerable 

customers, and Treatment to Tap, a sensor as a service business model to improve water quality. In the Transform round, 

we submitted three bids and were successful in securing full funding for The National Leakage Research and Test Centre 

(£5.3M), an ambitious, first of its kind leakage test centre for the sector to significantly fast forward technology development 

in this vital space, and phase 1 funding for Stream (£880K of a £5.7M bid), an open data platform for the water sector. 

Throughout  the  funding  competition  so  far,  we  have  won  a  total  funding  amount  of  £12.25M  for  eight  winning  bids.  In 

addition, we’ve submitted the most bids (21), secured the highest number of winning bids (8), and have secured £12.25M 

in funding which is already more than we originally contributed to the Ofwat fund for 2020-25 (£11.5M). In addition, we 

have also had success in securing funding from the Smart Factories Innovate UK bid (£50K), which will create a blueprint 

for water capture and re-use from an innovative semi-conductor factory, £100K from the Digital Catapult’s Made Smarter 

competition  for  a  novel,  cheaper  water  quality  sensor,  and  £500K  from  the  European  Space  Agency  for  collaborative 

project  with  MGISS  and  NGN  around  Interruption  Prevention  Alert  Service demonstrator.  We  are  going  to  continue  to 

leverage this momentum in future Ofwat and other funding mechanisms. 

Value from innovation  

During the last year we have been focusing on speeding up the achievement of value from innovation, by supporting the 

seed of an idea through to it becoming business as usual. We have a very active innovation pipeline with more than 80 

ideas being considered across the business. The estimated value of ideas in the pipeline, if successful is worth more than 

£37M. We actively support employees to come forward with innovative ideas and support their development. We have had 

some brilliant technologies adopted through this process which are now making a difference, such as the Pressure Vessel 

which can be quickly deployed to reduce interruptions to supply, and a burst rising main sensor which is a simple device 

that is deployed in rural wastewater sites to alert failure which is preventing pollution events. These are a few examples of 

how innovation is really making a difference to our customers, now and for a more resilient future.

Case study – Water Breakthrough Challenge  

We  have  secured  £1.8M  worth  of  funding  for  three  different  projects  which  will  help  to  further  improve  services  for 

customers and make operations more efficient. 

We’ve  acquired  the  significant  amount  of  funding  thanks  to  three  winning  bids  in  the  second  round  of  the  Water 

Breakthrough Challenge, Catalyst Stream competition ran by Ofwat and innovation foundation Nesta. 

The large-scale financial backing, which will see the money split between three different projects, will be a great investment 

into the region, and will support work into initiatives aimed at improving water quality, as well as wastewater and customer 

services. 

The first project to receive funding is called ‘Support for All’. This is aimed at helping to establish a region-wide cross-utility 

Priority Services Register so that customers in vulnerable circumstances can receive help from all their utility companies 

when needed. 

The  second  project  is  called  ‘Treatment-2-Tap’  and  will  see  engineers  adding  water  quality  sensors  to  the  final  leg  of 

water's journey from treatment works to tap. This will then be studied, in collaboration with four other water companies, 

and the data gained will help to further improve the water quality for the customer. 

The final project is known as SuPR Loofah (Sustainable Phosphorus Recovery) and this initiative involves the recovery of 

phosphorus from wastewater using an innovative, micro-algae coated on loofah material and held in place by a sustainable 

polymer coating. Once the ‘SuPR Loofah’ is full of phosphorus it will be removed, replaced and the phosphorus recovered, 

preventing environmental damage. 

All three projects are customer focused and are set to have a positive benefit to customers across the North East. 

Angela MacOscar, our Head of Innovation, said: “Our customers are at the heart of everything we do, and here we have 

three incredible projects that are set to deliver great benefits for them. 

 “We are incredibly proud that out of the 13 winning bids, we have managed to secure three of them  – this shows how 

Northumbrian Water is truly leading the way when it comes to innovation both in the region and in the sector. 

“I can’t wait to see what happens to all three of these projects over the coming months, and I’m looking forward to see 

each of them making a real-life difference to the people in our communities.”

OUTCOME 11: We help to improve the quality of rivers and coastal waters for the benefit of 
people, the environment and wildlife 

AMBITIOUS GOAL: Have the best rivers and beaches in the country 

AMBITIOUS GOAL: Have zero pollutions as a result of our assets and operations 

• 

Treatment works compliance – common  

•  Bathing water compliance – bespoke  

•  Pollution incidents – common 

•  Water Industry National Environment Programme (WINEP) – bespoke  

•  Delivery of WINEP requirements – bespoke 

Our care and respect for our natural environment goes far beyond  our regulatory requirements. We work constantly to 

protect and bring about improvements for our coasts, rivers, and watercourses in all areas of our operations.  

Our vision is to be the leader within our sector for environmental performance for our customers and communities - and 

we have achieved several significant successes towards this, including:  

•  We achieved the top four-star rating in the Environment Agency’s most recent annual Environmental Performance 

Assessment  and  secured  a  ‘green’  assessment  in  areas  such as  serious  pollution  incidents  and  self-reported 

pollution incidents among others.  

•  Our pollution numbers associated with combined sewer overflows have fallen by over 95%.  

•  Our work has also contributed to 32 of the North East’s 34 designated Bathing Waters achieving the top ratings 

of ‘excellent’ or ‘good’ in Defra’s most recent classifications (in 2021), up from 26 in 2013.  

•  We  also  have  an  ambitious  goal  to  achieve  net-zero  status  in  relation  to  our  operational  greenhouse  gas 

emissions  by  2027,  having  already  reduced  our  carbon  emissions  by  over  68%  since  2019,  significantly 

outperforming against our target.   

• 

This has all been achieved while offering our customers the lowest wastewater bill in England. 

We are proud of the level of environmental investment we committed to in the current five-year investment period, which 

reflects our customers’ priorities as we understood them pre-Covid, but we understand that times and expectations have 

changed.  

In November, we, along with all other wastewater companies, were contacted by the Environment Agency (EA) and Ofwat 

about  measures  to  ensure  permitted  ‘Flow  to  Full  Treatment’  requirements  are  being  achieved  at  our  Wastewater 

Treatment Works. This was followed by a further request from Ofwat in March 2022

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

We  are  investing  £45.56M  in  flow  measurement  schemes  up  until  2025.  This  will  give  us  much  greater  coverage  of 

MCERTS  (the  EA’s  Monitoring  Certification  Scheme)  flow  monitoring  and  have  completed  investigations  to  establish 

whether we can install the same monitoring to additional sites for completion between 2025 and 2030. 

We are complying fully with the Ofwat and EA investigations and provided extensive information to the EA and Ofwat in 

November and December last year. 

In early March 2022, Ofwat issued a formal notice (a Section 203 notice) requiring us to provide further information with a 

deadline  for  submission  in  early  April.  This  notice  is  a  formal  investigatory  step  and  indicates  that  Ofwat  will  carefully 

consider  the  information  in  light  of  our  legal  obligations.  It  does  not  necessarily  imply  that  any  enforcement  action  will 

follow, but it is a more formal process. We recognise the issue’s importance to our stakeholders and customers and the 

gravity of the investigation, and we fully complied with the requirements. 

Our investigations so far have shown that overall, across the 189 locations where we have these permits and based upon 

our  own  assessment  of  compliance,  we  have  identified  circumstances  where  we  may  not  have  always  achieved  the 

required FFT levels at four smaller sites. 

•  Seahouses Wastewater Treatment Works, which serves 2,579 customers, where we installed extra pumps in late 

March.  

•  Stokesley  Wastewater  Treatment  Works,  which  serves  8,318  customers,  where  it  appears  grit  and  silt  have 

penetrated part of our system, reducing the available flow. We have now corrected this issue.  

• 

Togston Wastewater Treatment Works, which serves 628 customers, where we are assessing the effectiveness 

of  recently  installed  new  pumps  along  with  checking  for  any  further  hydraulic  restrictions  on  site.  This  was 

completed at the beginning of June 2022.  

•  Newbiggin Wastewater Treatment Works, which serves 37,633 customers, has a unique system for pumped inlet 

flows. Analysis indicates that it is inconsistent in being fully compliant. We optimised site settings and controls, 

which enabled us to move the site to consistent and full compliance and supplemented this with a hydraulic study 

of the site, all completed by June 2022.  

For each of these sites we are now collecting data to confirm that they are operating in a fully compliant manner – this 

requires a period of time as the sites need to operate under periods of sustained heavy rainfall to verify full compliance. 

We  will  also  continue  further  investigations  of  additional  sites,  to  make  sure  we  are  compliant  with  our  environmental 

permits and will update customers and stakeholders appropriately.  

We publish regular updates on this matter on our website.  

Our challenge now is to demonstrate how we can do even more to invest to protect and enhance our rivers so we have 

committed to nine ambitious pledges that we believe will be effective for our unique water environment and make a real 

difference to our communities. 

1.  We will work with the Environment Agency, Natural England, The Rivers Trust and Catchment Partnerships 

to identify, and have plans in place to eliminate, all impediments to our rivers achieving good ecological status 

caused by our operations. 

2.  We will invest in monitoring to provide 100% near Realtime Data on all Storm Overflows by 2023.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

3.  We will introduce final effluent, in-river upstream and downstream monitoring to get a greater understanding 

of environmental impacts of treated water by 2030. 

4.  We will implement Water Quality monitoring at the highest priority Storm Overflow locations by 2025. 

5.  We will reduce spills from storm overflows to an average of 20 per year by 2025. 

6.  We will work closely with The Rivers Trust through our strategic partnership and North East Catchments Hub 

to focus on river needs for investment through catchment and nature-based solutions, and to identify at least 

2 inland bathing water sites where applications for designation can be made at the earliest opportunity. We 

are  proud  that  already  95%  of  the  NE  population  lives  within  an  hour’s  drive  from  a  beach  with  Good  or 

Excellent bathing waters. 

7.  We will work with partners to achieve 100% of coastal bathing waters at Good or Excellent by 2030. 

8.  We  will  work  in  partnership  to  improve  500km  of  bluespaces  (such  as  river  banks  and  accessible  water 

environments) for the public to enjoy in our regions by 2030. 

9.  We will double the number of our Water Rangers – our citizen scientist volunteers who are trained to help us 

monitor environmental conditions around rivers and take action to address wider river issues such as littering, 

fly tipping or signs of pollution. 

We have recently published A Vision for our Coasts and Rivers, a report that outlines the pledges and how we will play 

our part in enhancing the local environment. It details our new long-term commitments to water quality, and our programme 

of work to 2025 that will help us achieve our goals.

Treatment works compliance - PR19NES_COM15 

We have not achieved this PC.  

This  is  a  common  measure.  It  differs  slightly  from  that  reported  by  the  Environment  Agency  (EA)  in  its  annual 

Environmental  Performance  Assessment  (EPA)  of  water  companies  in  England.  This  measure  is  reported  as  the  total 

number of failing sites (rather than the number of failing discharges) where one or more numeric permitted discharges 

have been confirmed as failing in a calendar year. This is expressed as a percentage of the total number of discharges on 

the EA register. For both NW and ESW in 2020-25, this measure now includes both STW and WTW discharges and is 

subject to penalty for under-performance (EPA does not include ESW sites). 

Our result of 98.03% has slightly declined since last year and as this performance is below the 99.00% deadband we will 

incur a penalty of £0.579M.  

This result has been associated with three treatment work sites in our Northumbrian operating region (one STW and two 

WTW) and one WTW in the Essex and Suffolk area. The STW failing discharge was due to an ammonium failure with the 

WTW failures being chlorine (one works) and iron (two works) from a total of 204 eligible treatment works.  

We have completed extensive investigations to establish the root cause of these events and identified corrective measures 

to mitigate the likelihood of a reoccurrence. Most of the corrective actions have been fully implemented with the remainder 

nearing  completion.  These  corrective  measures  have  included  additional  enhancement  to  both  the  sites  operating 

procedures and preventive maintenance schedules  along with the installation of additional process infrastructure. Each 

failure has or continues to undergo a thorough investigation process to identify any further mitigation measures to avoid 

future failures.  

The EPA metric specifically applies to treatment works in the Northern region which have three failing discharges against 

a total of 177 (one STW and two WTW). 

Although 2021 has resulted in a penalty for performance below our PC we have continued to achieve our 4-star company 

status in the Environmental Performance Assessment (EPA) from the EA.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

We remain focused and proactive in using leading indicators in monitoring our treatment works taking regular samples that 

are analysed for compliance, including phosphorous and ammonia, and specific substances that may accumulate to cause 

a problem in the water environment.  

We  continue  to  do  our  best  to  deliver  against  the  challenging  new  standards,  whilst  also  adapting  to  challenging 

circumstances, as well as a very stretching settlement from Ofwat.  

We must also continue to be adaptive and plan to meet future requirements including the challenges of emerging themes 

whilst satisfying our continued obligations in contributing to a ‘Good’ Water Framework Directive (WFD) status in our rivers. 

Bathing water compliance - PR19NES_BES19 

We have achieved this PC.  

Our stretching bespoke measure is to contribute to all the region’s bathing waters being ‘Good or Excellent’. Previously for 

2015-20 our PC was to contribute to all the regions bathing waters being ‘Sufficient or better’.  

Covid-19 had impacted the Environment Agency (EA’s) regulatory bathing water sampling during 2020 and as a result, 

bathing waters were not classified for the 2020 bathing season in England. This meant that the classifications for 2019 

were taken forward into 2020.  

Bathing water classifications were assessed for the 2021 bathing season with 32 out of 34 bathing waters either Good (7) 

or Excellent (25).  

The two bathing waters that haven’t met our PC of ‘Good’ or ‘Excellent’ are Marsden (‘Sufficient’) and Cullercoats (‘Poor’).  

We have conducted a WINEP investigation at Marsden to understand the deterioration from Good in 2019 to Sufficient in 

2021. The classification is affected by significantly higher than normal sample results in both August 2018 and August 

2019 that are linked to rainfall events. The study has concluded that local diffuse sources represent the predominant cause 

and removal of our only asset, a storm overflow, would not improve the classification.  

The terms of this performance commitment provide scope for an exemption where it can be proved that NWL assets are 

not contributing to any deterioration in classification. We have written confirmation from the EA that this is the case for 

15 July 2022 
PAGE 104 OF 206 

 
 
 
 
 
 
 
 
 
 
 
NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

Marsden and accordingly have reported our performance for the year as 33/34 (or 97.06%) comprising 32 beaches rated 

as Excellent or Good along with Marsden rated as Satisfactory but with a written exemption confirmed by the EA. 

Cullercoats had deteriorated from Good in 2016, to Sufficient in 2017, and has been classified as Poor for 2018, 2019 and 

2021.  Due  to  the  break  in  classification  for  2020,  the  5-year  consecutive  count  before  de-designation  for  Poor  bathing 

waters has been reset in 2021. This means that the earliest Cullercoats could be de-designated due to five consecutive 

Poor classification will now be 2026 instead of at the end of the 2022 season.  

Our WINEP investigation at Cullercoats commenced in 2020 and builds on the extensive partnership investigations with 

the EA and local authority undertaken since 2017. A detailed review was carried out of all previous studies including the 

NEP investigation in 2011 that identified an uncharted polluted drainage culvert belonging to the local authority that was 

capped off from the beach. Further targeted investigations and surveys were then carried out to determine the most likely 

cause.  Indications  are  that  contaminated  groundwater is  the  most  likely  primary  reason  for  the  deterioration  in  bathing 

water quality and that there is no evidence that our assets have an impact. We have had positive engagement with the 

Cullercoats  Collective,  a  local  interest  group  with  wider-ranging  membership  including  members  of  Surfers  Against 

Sewage, but with a broad town-wide remit. We remain committed to working with our partners including North Tyneside 

Council and the EA to improve the seawater quality at Cullercoats for our customers, local businesses, and recreational 

users. 

Another local community group we’ve been engaging with is Marske Litter Action to develop public understanding of how 

our wastewater system works and promote our Bin The Wipe campaign. In 2022 we are training the group to be Water 

Rangers, to help us monitor environmental conditions and improve the coastal area. 

We continue to work in partnership to make improvements and maintain standards as seawater quality can be affected by 

many different sources, such as run-off from agriculture, seabirds and urban pollution, as well as from our assets.  This 

includes working closely with the EA to understand all bathing water quality compliance issues and identify priority beaches 

for closer attention. Our bathing waters continue to be among the cleanest in the country.

Pollution incidents (Category 1-3 Wastewater) - PR19NES_COM09 

We have achieved this PC.  

We  aim  to  avoid  all  pollution  and  our  PC  for  all  wastewater  category  1,  2  and  3  incidents  is  a  common  measure  for 

pollution using the EA’s EPA methodology.   

Our 2021 performance for category 1-3 wastewater pollution incidents was inside our PC target at  22.98 incidents  per 

10,000km of sewer and we have earned a reward of £0.227M.  

This performance reflects a decision by the Environment Agency to exclude a number of incidents which occurred during 

Storm Arwen from its assessment of our performance – as these were deemed to be outside our control. 

While  we  remain  an  upper  quartile  company  for  pollution  incident  performance,  we  are  disappointed  to  have  lost  our 

Frontier Company status for the first year since 2018. We are determined to regain this position in 2022 and beyond. 

One of the main reasons behind our increase in wastewater category 3 incidents was associated with power issues at 

sewage  pumping  stations  (SPSs).  These  were  either  related  to  the  incoming  power  supply  or  internal  power  issues 

affecting the service of the stations. We have conducted a thorough cause analysis to understand the reasons for these 

incidents and put in place measures to increase the resilience of these assets.  

We are pleased that our number of more serious category 1 and 2 pollution incidents remains very low at one in 2021, a 

category 2 incident at a sewage treatment works associated to a compliance issue. This compares to one in 2018, two in 

2019 and one again in 2020. Our aim is to have zero serious incidents. 

We continuously learn and improve our pollution performance through our company-wide zero-tolerance approach to it. 

By constantly examining all aspects of pollution through our pollution best practice group and learning from others, such 

as through the industry Pollution Reduction Task Force group, we target our efforts to effectively reduce the number of 

incidents. In April 2022, we updated our published Pollution Incident Reduction Plan which outlines the initiatives that we 

are conducting to further improve performance. Examples of the interventions in progress are: 

•  A programme to install innovative telemetry to more than 150 descriptively permitted STWs by 2025.   

15 July 2022 
PAGE 106 OF 206 

 
 
 
 
 
 
 
 
 
NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

•  We continue to develop, trial, and use innovative sensor and monitors, for example, smart air valve monitors on 

rising mains and low-cost monitors on sewers near to watercourses, to increase our visibility of the wastewater 

system.  

•  A new programme of find (CCTV) and fix (root cutting and lining) launched in 2021 targeting around 25km of high-

risk sewers initially and continuing into 2022.  

•  An action plan developed and delivered to inform developers (nationally and regionally) of the measures required 

to mitigate against pollutions occurring in our wastewater system. 

Outside of our measures of service for pollutions, we continue to work hard to reduce those incidents attributable to our 

water treatment and supply networks. There were 22 incidents in 2021, mainly on our water supply network that included 

zero serious incidents. We continue to develop our processes, procedures, and response to these types of incidents that 

typically involve a burst water main and chlorinated water impacting a nearby watercourse. This has included environmental 

impact and pollution process training for all our water distribution employees and contractors.   

The EA’s expectation is that we will pro-actively ‘self-report’ at least 80% of all pollution incidents to them rather than rely 

on others to point out a problem. We consistently achieve high levels of self-reporting in surpassing  the 80% requirement 

with an improvement to 89% in 2021 compared with 81% in 2020 and 80% for 2019. From 2020 onwards, the EA also 

expects a self-reporting level of 90% or more for sewage pumping stations (SPSs) and sewage treatment works (STWs). 

We again achieved 100% self-reported in 2021 against this new metric having attained 100% in 2020 also. 

We  were  prosecuted  for  a  pollution  incident  that  occurred  in  May  2017  at  Heads  Hope  Dene  in  Castle  Eden  County 

Durham. This was caused by a blockage in our combined sewer causing raw sewage to enter the stream. We are investing 

£5M on upgrades to the sewer network in the area to protect the environment and improve the resilience of our assets.

Case study – Saltburn, a mini treatment works  

In February 2022 a sewerage treatment facility was built from  scratch in Cat Nab car park, Saltburn, while repairs to a 

damaged sewer pipe took place.   

A third party working in the Cat Nab car park on behalf of Redcar and Cleveland Council damaged the sewer pipe that 

pumps  sewage  and  storm  flows  to  be  treated  at  Marske  sewerage  treatment  works.  A  sheet  pile,  as  part  of  riverbank 

stabilisation  work,  was  driven  through  the  pipe  which  crosses  underneath  the  watercourse.  When  the  pipe  is  fully 

operational, it carries up to 200 litres a second.   

We  worked  on  a  construction  plan  to  carry  out  a  repair  and  install  environmental  mitigation  measures. The  location  of 

where the main was damaged, next to the watercourse, made this a complex repair. Our team came up with an innovative 

idea to build a bespoke mini treatment works.  

It was an industry first for a bespoke facility of this scale to be built and in such a quick turnaround (within two days). The 

plan was to construct a treatment works that would capture as much of the flows from the pipe as possible and will help us 

to protect the environment even more. 

We worked closely with the Environment Agency and to help protect the environment we ran tankers continuously and 

placing straw bale dams in the beck to collect debris.  

Once the treatment works was built, we started to dig into the ground to expose the pipe and assess what equipment and 

fittings were required to fix it. After digging down almost five meters to the pipe, damage was also found to a second pipe, 

adding to the repairs needed.  

The location and landscape made the repair especially complex, with a high degree of environmental and personal risk, 

but we used a range of methods to mitigate those, including:  

•  Creating a pop-up sewage treatment works within two days to reduce the environmental impact.  

•  Re-routing the course of the beck to allow safer working.  

It took five weeks to fully complete the repair of the pipes damaged and remove the temporary treatment works and other 

mitigations. The project was a truly one team effort, requiring input from a wide range of colleagues, from operations and 

project management, to support from our Customer and Communications teams, as well as Esh-Stantec.

Water Industry National Environment Programme (WINEP) - PR19NES_BES31 

This is a bespoke PC which is reputational only until 2025, when a penalty could apply for underperformance. It’s measured 

by  the  cumulative  number  of  WINEP  schemes  completed  each  year  across  our  operating  areas  (including  both 

Northumbrian Water and Essex & Suffolk Water). It is limited to schemes that were confirmed on 1 April 2019 within WINEP 

and therefore had certain (green) status. Only sites signed off  by the Environment Agency (EA) can count towards the 

measure. 

The WINEP is a key part of the overall programme of measures to meet the requirements of the Environment Agency 

(EA)’s Water Industry Strategic Environmental Requirements (WISER) document. This includes objectives to meet Water 

Framework Directive (WFD) ‘Good’ status in our rivers by 2027 and prevent deterioration in status, together with other 

international regulatory drivers, including the Urban Wastewater Treatment (UWWT) and Habitats Directives. The EA sets 

an expectation in its WISER guidance that companies will deliver 100% of the environmental improvement schemes listed 

in WINEP. 

We work very closely with our local EAs to make sure we have a common understanding of the specific requirements of 

our obligations, and to make sure the mitigation measures we implement will satisfy the WINEP’s environmental objectives. 

We have regular engagement with local EA representatives and provide information, as required to make sure we agree 

on key decisions throughout a scheme’s delivery cycle. A governance process has been agreed, based on an EA guidance 

document, to avoid late decisions on any changes to the obligations and in developing the evidence requirements for EA 

sign off on completion. These include procedures for Change Protocol and for WINEP measures sign off. 

In response to Covid-19, the EA acknowledged anticipated delays to scheme delivery due to the restrictions during lock-

down on water company and laboratory work. Reflecting this and other developments, the EA has agreed a revised delivery 

profile for schemes up to 2025. 

We are on track with delivery against the EA’s revised profile, however for our PC, Ofwat requires us to report against the 

original expected delivery profile – which indicates that we are behind schedule.  

Our targets for the first four years are reputational only, but if we should fail to complete the agreed total by 31 March 2025, 

we would pay a financial penalty in 2024/25.

The EA also reports WINEP delivery performance in its Environmental Performance Assessment (EPA). For this it uses 

its revised delivery profile and hence the EPA indicates that we are on track with WINEP delivery. 

Delivery of Water Industry National Environment Programme requirements - 
PR19NES_NEP01 

This  is  a  bespoke,  reputational  only  PC  that  tracks  our  ability  to  meet  or  not  meet  our  requirements  for  WINEP.  The 

measure  specifically  tracks  the  completion  of  the  required  schemes  in  each  year  and  Ofwat  specifies  performance  for 

2021/22 will be reported based on the latest WINEP programme on 31 March 2022, and the schemes delivered by this 

date.  

Failing to complete the designated WINEP schemes for any given year would result in a ‘not met’ result. 

All our forecasted WINEP deliverables (post accepted changes) for 2021/22, have been completed for sign off and there 

will be none recorded as ‘not met.’ 

While this ODI measures for this five-year period, it is like the EPA measure, against which we have consistently delivered 

100% of schemes since its introduction in 2011.

Case study – WADER  

We are taking part in a multi-million pound project aimed at improving river water quality in Northumberland. 

The LIFE Water and Disturbance Environmental Restoration (WADER) project aims to improve the ecological condition of 

more than 49,000 hectares of habitat and water quality for the species that depend on them. 

Focused on the River Tweed catchment, Tweed Estuary and Northumberland Coast, the Natural England-led project sees 

our people working to help reduce nitrates entering the water from agriculture. 

The Tweed catchment and estuary support internationally important over-wintering birds, such as the purple sandpiper 

and turnstone, as well as Arctic tern breeding colonies, and will help to control invasive species. 

Other partners include the Environment Agency, Tweed Forum and Newcastle University. 

Funding from partners and EU LIFE totalling £5.8M will see the five-year project deliver COP26 conservation pledges. EU 

LIFE is the European Union’s funding instrument for the environment and climate action. 

Our involvement represents part of our Water Industry National Environment Programme (WINEP) work, complementing 

its own investment in reducing the impact on water quality from its own operations and assets. 

Rob Cooper, one of our Catchment Advisers, said: “This beautiful part of Northumberland is so important for these species, 

and for those who love to visit and enjoy the surroundings that nurture them. 

“It’s  so  important  that  we  work  with  partners  on  projects  like  this,  supporting  other  industries  and  protecting  our 

environment. 

“It’s vital that the interaction between land management and river water quality is looked at holistically, if we are to make 

the improvements, we, our customers and communities, want to see. 

"Our efforts to support agriculture in reducing nitrate loss  from fields into water courses and aquifers  – water stored in 

underground rock - complements everything we are working to achieve in terms of our own operations.”

leading by example 

AMBITIOUS GOAL: Be leading in the sustainable use of natural resources, through achieving 
zero avoidable waste by 2025 and being carbon neutral by 2027 

•  Greenhouse gas emissions – bespoke  

•  Bioresources – bespoke 

Our ambition is to be the first water company to achieve Net Zero carbon emission by 2027 and we continue to remain on 

track to achieve this.  

Greenhouse gas emissions - PR19NES_BES21 

The chart below shows the reduction in our emissions compared to 2019/20 baseline figures.  

This is a bespoke PC that incentives us to reduce greenhouse gas emissions arising from our operational activities. The 

baseline was re-calculated for 2021/22 using the newest carbon accounting workbook. 

This year we have reduced our operational emissions to just 22 thousand tonnes of CO2e – down from 69 thousand tonnes 

in 2019/20. 

We have achieved this by: 

• 

Installing our first large scale solar array at Lumley Water Treatment Works, with six more large scale farms being 

built this year. 

•  Being the first and are the only water company to use 100% of our sewage sludge to create energy (or power 

from poo), and we’ve enhanced our activities in energy creation further with the implementation our second Gas 

to Grid plant at Bran Sands. 

•  Using biomethane purchased through the market to reduce our reliance on natural gas.

•  Continuing to be efficient in our travel – avoiding unnecessary journeys and travelling by public transport. 

• 

Leading the industry with our offshore wind Power Purchase Agreement (PPA), which was the first of its type in 

the  UK.  This  10-year  deal  has  us  sourcing  approximately  30%  of  our  electricity  demand  from  the  Race  bank 

offshore wind farm. 

•  Powering all sites using renewable electricity. 

•  Using electric vehicles wherever possible. 

We are on track to achieve zero avoidable waste by 2025. This will mean eliminating, re-using, or recycling 90% of our 

waste from operations, developing resource recovery technologies and working with partners to contribute to the circular 

economy in their regions. 

Our figures have been subject to external third party assurance to confirm compliance with ISO14064, a copy of this report 

can be found here.  

For our performance in this area, we are receiving a reward of £7.646M.  

Bioresources - PR19NES_BES22 

We have achieved this PC.  

This bespoke PC is reputational only. The measure for bioresources performance is the percentage of sewage sludge 

treated and converted to biosolids at one of our two Advanced Anaerobic Digestion (AAD) sites and the percentage of 

biosolids that are beneficially recycled to land.  

Our aim is to continue to treat 100% of our sewage sludge together with any imported organic material through the AAD 

process, and for 100% of the resultant biosolids to be safely and efficiently recycled to agricultural land. Our performance 

has remained at 100% achievement, therefore fully maintaining our committed performance which was first achieved as 

early as 2014/15. We are also the most efficient company in this area, and our  industry leading strategy remains at the 

forefront of the sector and is a clear example of our continued aspirations to drive innovation and excellence.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

Key enablers in delivering the strategy have been:  

•  Continued optimisation of two centralised AAD sludge treatment centres for all our bioresources and for trading 

in the bioresources market. We have regularly taken in bioresources to support other neighbouring companies on 

an ad hoc basis. 

•  Harnessing  the  opportunity  of  upgrading  biogas  to  biomethane,  and  injection  into  the  natural  gas  grid  at  both 

sites. We are the only company to have 100% of our energy-rich biogas used through this valuable route.  

•  A transport strategy based on a network of local dewatering sites at six strategic sludge handling centres and 

onward transport of sludge cake to the two AAD sludge treatment centres.  

• 

Fertiliser biosolids products recycled safely and beneficially to agriculture under the Biosolids Assurance Scheme 

(BAS).  

The  EA’s  Satisfactory  Sludge  Use  and  Disposal  metric,  that  forms  part  of  their  annual  Environmental  Performance 

Assessment (EPA), has been suspended since 2018 with shadow reporting only, however, it will be included for the 2022 

calendar reporting year.  

We confirm that all regulations and good practice codes have been complied to under the existing EPA metric. We continue 

to work closely with the EA in the development of the EA’s National Sludge Strategy.

•  Water environment improvements – bespoke  

Water environment improvements - PR19NES_BES20 

We have achieved this PC.  

This is a bespoke measure with this being the first full year of our programme following feasibility work in 2020/21.  

Linking improvements to public access is an innovative partnership approach to investing in the environment. All water 

environments are in scope, including lakes and reservoirs, streams and rivers, canals, wetlands, coasts, and beaches. 

Improvements must cover at least two out of three aspects of access and recreational facilities, wildlife and biodiversity, 

and water quality, and must include elements above our regulatory obligations. 

We have continued to outperform our PC of 10 km, achieving 34.6km of water environment improvements through delivery 

of 10 partnership projects across our NW and ESW operating areas.  

We’ve worked closely with the Water Environment Governance Group (WEGG), an independent group made up of external 

expert stakeholders who are passionate about improving the environment, which helps steer our activity and approves and 

signs  off  projects  against  the  ODI.  This  year  we  have  launched  a  new  funding  scheme  –  bluespaces  –  to  provide  the 

platform for developing and delivering partnership projects to support this ODI.  

We will receive a reward of £189,000 for our performance this year. We committed to reinvest at least 50% of any reward 

received above costs in new water environment projects. This year we have agreed an internal target to improve 248km 

of accessible water environments in our regions by 2025, which will see us investing close to £1M in above and beyond 

activities throughout 2020-25 to improve the water environment in partnership for the benefit of our customers. The level 

of  investment  annually  in  years  three,  four  and  five  will  be  substantially  above  the  50%  reward  reinvestment  level  we 

committed to in developing this bespoke ODI. We have invested £171,139 in water environment improvements in year 

two, including in staff resources and investment in projects.

The Science, Water and Nature Conference took place in Colchester, and the main message that emerged from the two-

day get-together was that building new collaborations is key for a sustainable future. 

The event began with a video message from His Royal Highness The Prince of Wales, a champion of sustainability for 

over 50 years, before delegates learned about the biodiversity challenges faced by the water industry, landowners, and 

economists. 

Speakers included our Water Director, Keith Haslett, Ian Barker, from the Institute of Water, Matthew Morris, the Duchy of 

Cornwall’s land manager, HM Treasury economist Lucy Watkinson and David Hill, Chairman of the Environment Bank.  

A site visit to the spectacular Abberton Reservoir, which was enhanced in 2015, allowed attendees to see at first-hand a 

perfect example of what can be achieved through diverse partnerships. 

Three workshops on the second day allowed attendees to break off into smaller groups and focus on future innovation, 

regulatory and legislative changes, and costings. 

Heidi Mottram, our Chief Executive, said: “The water sector is totally dependent on a healthy and thriving natural world for 

its core purpose, so I believe we have a responsibility to be at the forefront of leading the charge to collaborate across 

sectors and put individual interests aside for the good of our shared natural environment and society. 

“There couldn’t be a better time to be having these conversations. With recent and upcoming changes to the legislative 

and regulatory outlook, there is huge opportunity to think and do things differently. 

“We need to think at a landscape scale to deliver natural capital initiatives that deliver multiple benefits. 

“Building new collaborations is essential for a sustainable future; and I am excited to see what new partnerships will be 

forged from this conference.”

Catchment management  

Catchment management covers the whole water cycle and this ambitious goal links across our water, wastewater, and 

conservation activities. We carry out catchment activities both across our own network and assets, and in partnership with 

others, working to influence and to make shared decisions to improve the environment and showing leadership in integrated 

catchment management.  

We work towards this ambitious goal in various ways: 

• 

Integrated Catchment Planning 

•  Collaborative working at regional scale  

•  Catchment Based Approach (CaBA) and Catchment Partnerships  

• 

Landscape partnerships  

•  Catchment and Nature-based solutions  

•  Water environment  

•  Water resources  

•  Conservation 

During 2021/22 we delivered the following:  

Field to Tap – farm advice and grants programme: 

•  We carried out advisory visits to 39 farms and had telephone conversations with a further 26 farmers.   

• 

23  grants  were  offered;  £34,151  of  grant  funding  was  paid  to  farmers  in  our  highest  risk  areas  and  a  further 

£163,247.50 in grant funding has been agreed and will be paid when the farmer completes the work.   

•  Capital grants were for on-farm interventions such as clean and dirty water separation, muck storage, pesticide 

handling areas, cover crops, precision spraying equipment and soils assessments. 

• 

In addition, we attended 16 events, organising/co-hosting seven of them and presenting at six, reaching a total 

audience of more than 830 people. 

South Tyne and Blackwater Holistic Water Management Projects: 

These two projects had a slow start due to Covid-19 lockdowns, but despite this we brought together stakeholders to 

form online advisory groups and successfully ran online applications for grants. 

•  On the South Tyne, the Advisory Group met three times and a window for grant applications was opened in June 

2021.  Four  applications  for  funding  were  received,  three  for  river  restoration  projects  and  one  for  a  research 

‘sediment fingerprinting’ project. All four applications met the project’s aims of delivering river restoration and/or 

biodiversity benefits and all four projects were approved, to a value of £120,223. Further grant applications are 

expected in 2022-23.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

•  On the Blackwater, the lapsed Blackwater Partnership has been reinstated and a window for grant applications 

opened in Autumn 2021. One application was received, and approved, for support towards a beaver enclosure 

and on-farm water storage to a value of £35,000. A further window for grant applications will open again in 2022 

and further grant applications are expected.   

• 

In all cases the grant applicants had secured additional funding, effectively leveraging our financial support into 

delivering larger projects to benefit the wider environment.   

Peatland Restoration 

In 2021/22 we provided £100,000 of funding to the Peatscapes Partnership to support peat restoration as part of the Tees-

Swale project, addressing issues of colour in our raw water sources in the Tees catchment.   

Berwick Nitrates Investigation and Field Trials 

The Measures Specification for the WINEP Investigation into rising nitrates in our groundwater sources in the Berwick area 

required  us  to  look  at  both  catchment  management  interventions  and  the  underlying  hydrogeology  to  improve  our 

knowledge of the nitrate issue and better understand the actions that could be taken to prevent further deterioration. It also 

included  support  for  a  PhD  study  which  aimed  to  design  a  better  monitoring  system  for  soil  nitrate  concentration  and 

leaching events in the Fell Sandstone catchment study area. 

We engaged with farmers in the geographic catchment overlying the aquifer. Due to Covid-19 restrictions we were unable 

to  establish  a  formal  partnership  as  we  had  originally  planned,  but  instead  engaged  1-2-1  and  we  are  now  building  a 

partnership following Covid restrictions being lifted. 

In the Berwick area we have trialled a range of on farm interventions to help change behaviour around nutrient applications 

and to improve Nitrogen Use Efficiency (NUE) in the catchment, despite the challenges of face-to-face engagement during 

the pandemic. The trials work will support and encourage the uptake of these mitigation options as well as informing the 

design of a grant scheme for PR24 (2025-30) catchment interventions.

Case study – new partnership aims focus on the North East environment  

We’ve teamed up with The Rivers Trust to form the North East Catchments Hub, a new approach to drive work that will 

inform investment to benefit water and the environment in the region. 

This  exciting  new  partnership  will  bring  together  local,  regional,  and  national  expertise  in  a  regional  Hub  to  develop 

improvements for water quality and the wider environment around the North East. 

As well as playing an important part in the creation of our PR24 Business Plan for 2025-30, the Hub – an industry first – 

will create three new full-time job roles within three of the region’s rivers Trusts (Tyne, Wear, and Tees) plus an extra part-

time managerial role. 

The Hub will form a focal point for our planning and partnership working to improve the environment through catchment 

and nature-based solutions. The combined expertise and best practice will create opportunities to unlock additional funding 

and consider alternative, sustainable ways to invest for environmental benefit. 

It  also  builds  on  the  success  of  the  Northumbria  Integrated  Drainage  Partnership,  which  brings  us  together  with  the 

Environment Agency and all 13 lead local flood authorities in the North East region, to reduce flood risk in partnership and 

in a way that promotes sustainable drainage. 

Mike Madine, our Head of Wastewater Service Planning, Quality and Performance: “This partnership with The Rivers Trust, 

and  the  creation  of  the  North  East  Catchments  Hub,  is  an  industry-leading  approach  to  delivering  improvements  to 

watercourses  and  the  wider  environment.  It  will  create  opportunities  to  invest  effectively  and  significantly  enhance  the 

things we can do in this area. 

“Catchment planning is something that no individual organisation can substantially tackle alone, and that’s recognised by 

both ourselves and The Rivers Trust. It’s really exciting to be coming together like this, because we know we can do so 

much more by working in partnership.” 

Dr Ceri Gibson, CEO at Tyne Rivers Trust, which will be hosting a citizen science catchment monitoring demonstrator as 

part of the work, said: “Catchment Partnerships are an established and effective mechanism for identifying and delivering 

holistic improvements for rivers and land management. Everyone involved appreciates that working together to collect and 

share critical information will reap greater benefits. We are pleased to apply our local expertise and lived knowledge in 

working with natural processes to support Northumbrian Water in identifying and developing the most appropriate nature-

based solutions throughout the region.” 

The partnership is initially for one year, but its remit includes developing a platform for growth into future years.

THEME SIX: BUILDING SUCCESSFUL ECONOMIES IN OUR REGIONS 

OUTCOME 13: We are proud to support our communities by giving time and resources to their 
important causes  

AMBITIOUS GOAL: Be the most socially responsible water company 

Following the launch of our new Purpose statement in 2021, we have this year updated the Our Purpose report, published 

as part of our suite of corporate annual reports. In consultation with customers, we have identified the accreditations that 

demonstrate us living up to our Purpose statement, and the measures through which we will track our commitment to it.  

We  also  launched  a  new  community  investment  strategy  in  2021  linked  to  our  Purpose.  This  focuses  our  community 

investment  activity  in  three  specific  areas  that  are  tied  to  Ambitious  Goals  set  in  our  Business  Plan  and  supported  by 

customers. These are in areas where we believe we should be the identified lead in our communities because they are 

central to our Purpose and where our leadership is crucial for success. These are: 

•  Ending Water Poverty. 

•  Water For Health. 

•  Protecting The Water Environment. 

We seek to work towards these goals through a variety of different approaches: 

• 

Financial contributions – such as through our Branch Out grants scheme, through which we invested £66,500, 

which  helped  our  partners  bring  in  additional  funds  in  excess  of  £2M;  or  funding  the  SeaScapes  Landscape 

Partnership project on the Durham coast through investment of £370,000 from 2021-2025. 

•  Volunteering – through our Just An Hour scheme, where 37% of our employees volunteered for 235 community 

and charitable causes, including local food banks, WaterAid and beach cleans; while our partnerships with Wildlife 

Trusts have leveraged £241,000.  

•  Educational impact – our Ripple Effect water efficiency programme has almost 4,000 engagements; and 9,586 

took part in our Powered By Water health programme. More than 100 16- to 25-year-olds took part in a virtual 

assessment centre at our Innovation Festival – which is set to help them understand how to be successful when 

applying for jobs, assessing skills that are core to many career areas. 

•  Playing a leadership role – including Chief Executive, Heidi Mottram, speaking on behalf of the UK water sector 

at the Marrakech Partnership for Global Climate Action event at COP26; while our ‘Give Back’ sprints at our 2021 

Innovation Festival enabled charities and community groups to tackle their own innovation challenges. 

Overall, we have once again delivered on our long-standing practice of investing in our communities (more than 7% of our 

profits were reinvested).  

We  have  again  achieved  significant  external  accreditation  for  our  responsible  business  practices.  This  includes  being 

named on the Ethisphere Institute’s World’s Most Ethical Companies list for the eleventh time in 12 years, and again being 

the  only  water  company  featured.  We  were  also  the  first  water  company  to  achieve  the  Good  Business  Charter 

accreditation, backed by both the CBI and TUC. Business in the Community’s Responsible Business Tracker cited us as 

top performers for nature stewardship and digital transformation, while we were also featured as a good practice example 

in BiTC’s recent Embedding Purpose: Lessons from Business report.

several further ways:  

• 

ISO accreditations for Environmental Management, Asset Management and Emissions Reporting.  

•  Good Business Charter. 

•  BiTC Responsible Business Tracker.  

•  Awarded Advanced Good Work Pledge by North of Tyne Combined Authority.

Case study – Drop Swap  

Our  new  charity  cash  boost  initiative  has  seen  hundreds  of  thousands  of  e-drops  donated  by  customers  to  help  local 

charitable causes in both our Northumbrian Water (NW) and Essex & Suffolk Water (ESW) operating areas.  

More than 370,000 e-drops were donated by NW customers and more than 211,000 by ESW customers to the nominated 

charitable causes over the last two month voting period through using our free app.   

Drop Swap sees tens of thousands of pounds being donated every year with customers deciding where the funding goes.   

We’re helping organisations such as Feeding Families, Oasis Community Housing and Little Sprouts in the North East and 

CYP Yellow Door, Southend Foodbank and Waveney Foodbank in Essex & Suffolk. All the good causes receive a cash 

donation and are offered support through our employee volunteering programme, Just an Hour.  

Louise Hunter, our Corporate Affairs Director, said: “We already support our local communities in many ways – gifting time 

and expertise via our amazing  employee volunteers to  donating cash  and equipment to community and  environmental 

projects.  

“The Drop Swap initiative is a fantastic addition to the great support we give our communities and it will help the charitable 

causes that matter the most to our customers. The idea originally came from a session with our customers at our 2019 

Innovation Festival and so I’m especially pleased to see it brought to life as a great example of how our customers can 

shape how we deliver our services.  

“We want to help as many deserving causes as possible, through this funding channel, across our local communities of 

the North East, Essex, Suffolk and the London Boroughs. We’re urging customers to download and start using our free 

app to help the causes that are close in their hearts.”  

The app is available for customers to use around the clock to access services, such as updating water meter readings and 

making account payments. Customers will be rewarded with ‘e-drops’ to vote for their local charity of choice when using 

the app and can nominate other charitable causes to benefit from future support.  

Alex  Hawkins,  Charity  Manager  at  CYP  Yellow  Door  said:  “We’re  grateful  to  have  been  involved  in  Essex  and  Suffolk 

Water’s Drop Swap initiative, where we were nominated for some community funding. It’s a great incentive, and we’re over 

the moon with the number of customer votes we received for our cause. Thanks to everyone who voted, and the donation 

from Essex & Suffolk Water will help support the fantastic work we do in the community.”

FOR YEAR ENDED 31 MARCH 2022 

Juliet Sanders, CEO of Feeding Families said: “We’re grateful to have been involved in Northumbrian Water’s Drop Swap 

initiative, where we were nominated for some community funding.  

“It’s a great incentive and we’re thrilled with the number of customer votes we received for our cause. Thanks to everyone 

who voted and the donation from Northumbrian Water will help support the fantastic work we do in the community. This 

year it is needed more than ever and so it couldn't come at a better time.”  

We’re delighted to be working with Essex Community Foundation and County Durham Community Foundation, helping to 

deliver this new initiative across the whole of its operating area. This extends a longstanding partnership through which 

thousands of pounds worth of project grant funding has been delivered in the area.  

Sharing their feedback about DropSwap our customers have said: 

“A brilliant way to help water services and accounts to run smoothly and help good causes as a result.” 

“A great idea and very good that it has been created by a water company.” 

"I think Drop Swap is an amazing thing to do -giving back and helping charities is such a lovely thing to do so I absolutely 

love it." 

Case study – Ground breaking ethnicity programme  

We have been part of a ground-breaking ethnicity programme, to help attract a more diverse workforce. 

By participated in the Workforce Integration Network (WIN) Design Labs programme, launched by the Equal Group and 

the Greater London Authority, we aim to tackle the under representation of the Black, Asian and minority ethnics (BAME) 

community, particularly young black men, within the infrastructure and construction sectors. 

Interactive sessions and workshops were designed to help the eleven companies involved engage with a more  diverse 

talent pool, with a targeted approach towards recruitment. 

As part of the programme, we’ve developed a detailed action plan. Some of our commitments include: 

•  Working with diverse recruiters to increase the representation of the BAME community within the water company 

and providing diverse interview panels. 

•  Diversifying the supply chain by refreshing the responsible procurement strategy and carrying out sustainable 

procurement assessments. 

•  Upgrading our HR systems to allow people to self-disclose or update their ethnicity / religion / sexual orientation 

at all recruitment stages from interview to even years into the role, to understand how sustainable recruitment is 

for diversity, inclusion and equity. 

We  also  plan  to  launch  a  four-year  diversity  and  inclusion  strategy,  which  will  see  employee  network  support  groups 

established and a series of online learning events delivered. 

Our Diversity, Inclusion and Wellbeing Manager, Michael Nicholas, said: “Essex and Suffolk Water is committed to being 

reflective of the communities we serve but currently we have room for improvement in this area.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

 “Taking  part  in  this  invaluable  project  and  developing  an  action  plan  is  a  positive  step  forward  to  creating  a  diverse 

workforce and it springboards our commitment to being the national leader on diversity and inclusion within our industry.” 

A spokesperson at the Equal Group, said: “We are delighted Essex  and Suffolk Water are committed to increasing the 

representation of young Black men in their organisation through the publication of their action plan. 

“Essex and Suffolk Water have been such active participants in the GLA WIN Design Lab programme and we look forward 

to seeing them, and continuing to support them, in creating a more diverse workforce.” 

OUTCOME 14: We work in partnership with companies and organisations to achieve the goals 
that are most important to our customers  

AMBITIOUS GOAL: Spend at least 60p in every £1 with suppliers in our regions 

We have achieved this PC.  

As one the largest businesses in the regions where we operate, and in keeping with our commitment to our communities, 

we believe it is important to maximise the positive impact of our spending. We therefore prioritise working with a supply 

chain that upholds our social, economic, and environmental standards and shares our vision of continuous improvement. 

After making strong and sustained progress since 2017/18 we are delighted to have reached this target over the past year, 

with local spending in 2021 at 60.34%, up from 58% in 2020. 

Several actions over the past year have helped to get us to this level: 

• 

Training and support delivered around the business through our ‘spend wisely’ campaigns, making sure teams 

are taking into consideration local sourcing when getting quotes for work.  

•  Contributions at events to share insights and access to opportunities with local suppliers. These include taking 

part in a programme to help County Durham businesses get ready to win construction work, and an Innovate UK-

funded  event  delivered  by  RTC  North  helping  businesses  who  wish  to  break  into  or  grow  within  water  sector 

supply chains. 

•  We  have  established  a  great  network  with  other  North  East  organisations  through  the  County  Durham  Pound 

group who have similar same goals and challenges to us regarding local spend and social value. This will assist 

us with spend analysis to show leakage outside of the local area and where new opportunities lie. 

To  calculate  our  local  procurement  spending,  we  established  a  baseline  by  defining  local  procurement  and  mapping 

suppliers to local and non-local categories. We define ‘local spend’ as spending with suppliers with a postcode that falls 

within its operating areas. This is based on the ‘pay site’ defined on the supplier’s invoices.  

In calculating local procurement expenditure, we include both capex and opex, but exclude certain spend categories, such 

as power, banking payments and inter-company payments. Excluding these items removes approximately 20% of total 

expenditure.  

For smaller companies, the invoice location is generally near  where the company is based and where their employees 

work and live. However, for companies operating over larger geographical areas, using invoice postcodes is less effective. 

Examples include temporary staffing contractors and capital framework partners who have a head office out of our regions

FOR YEAR ENDED 31 MARCH 2022 

but source our requirements from our local areas. To address this, a manual adjustment is made to better reflect where 

their employees work and live.  

In the last year we updated our Responsible Procurement Strategy, through which we have developed the ‘Impact Initiative 

7’.  This  sets  out  a  series  of  key  activities  within  seven  key  initiatives,  which  we  believe  will  make  the  biggest  positive 

difference when sourcing goods and services. 

As part of this, to enable us to achieve the strategy’s outcome to protect relationships with local suppliers and continue to 

create awareness and opportunities, we have identified four key activities: 

•  Maintain 60p in every £1 of supply chain spend with local businesses in our operating regions in the North East, 

Essex and Suffolk. 

•  Build and maintain external relationships with local organisations to offer business mentoring and provide meet 

the buyer events. 

•  Provide a pipeline of tendering opportunities on our website and use social media platforms such as LinkedIn to 

alert businesses of upcoming opportunities. 

•  Membership of the County Durham Pound – a collaborative group of local partners who seek to work together to 

increase  collective  local  spending,  create  business  Opportunities  for  local  SMEs,  VCSEs  and  other  local 

businesses. 

Our focus now will be on at least maintaining this level until 2025 and beyond and considering how we can do more to 

make sure the economic benefit of this spending is as big as possible.

Material issues or circumstances 

No other material issues or circumstances were considered. 

Deloitte  LLP  have  carried  out  assurance  on  the  ring-fencing  certificate,  in  accordance  with  the  Company’s 

Instrument of Appointment. The assurance was in the form of agreed upon procedures, and the report can be found 

[on our website]. 

CONDITION P26 (CREDIT RATING) 

The Directors confirm that throughout 2021/22 the Appointee has ensured that it, and an Associated Company as 

issuer of debt on its behalf, has maintained an issuer credit rating which is an investment grade rating. 

VIABILITY STATEMENT 

When considering long-term viability the Directors note that, in their opinion, the PR19 FD and the amendments 

made by the CMA in March 2021 still result in a settlement which is extremely challenging. The level of asymmetric 

risk in the settlement package is significant and not matched by the level of return and allowed costs are insufficient 

for an efficient company like NWL to deliver the stretching service levels set out in the FD for its customers. This 

also results in lower financial headroom available for the management of downside shocks and there is likely to be 

pressure on projected credit ratings as reflected in the current negative outlook from S&P. 

Financial forecasts over longer-term timeframes are inherently subject to more risk that the assumptions adopted 

will not be realised. As set out above, the Directors have confirmed that the business remains a going concern. In 

considering the longer-term viability, the Directors note the challenges inherent in the PR19 FD referred to above 

and that some of the downside stress test scenarios would place pressure on projected credit ratings in the next 

three years, particularly higher operating and capital costs. The longer-term view beyond three years assumes that 

the 2024 price review will provide a sufficient rate of return to enable the Company to finance its functions for the 

period  2025-30,  as  well  as  setting  stretching  but  achievable  targets  and  allowing  sufficient  totex  to  enable  an 

efficient company to meet its obligations and service level targets. 

The Directors have assessed the future prospects of the Company and consider that the Company should be able 

to manage its business risks, continue to operate and meet its liabilities as they fall due over the eight years to 

March 2030 given the long-term nature of the business.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

In arriving at their conclusion, the Directors have taken into account: 

• 

• 

the Licence which is in place on a rolling 25 year basis; 

the Board’s five year plan, extended to eight years for the purposes of this assessment and updated to 

reflect current macro-economic circumstances; 

• 

revenue from wholesale and household retail price controls to March 2025 provided by the PR19 FD, as 

revised by the CMA in March 2021; 

• 

the financial strength of the Company at the balance sheet date and the fact that the Company has a 

£450m committed bank facility as back up liquidity, of which £283m was undrawn, maturing in December 

2025 with the intention of extending until 2030 in due course; 

• 

the Board Treasury Strategy, approved in April 2022, which sets out a framework for raising c.£1.3bn of 

funding over the next four years to meet borrowing requirements; 

• 

the key financial ratios over the planning horizon of the Company’s financial forecast to March 2027 and 

extended forecast to March 2030, as reflected in investment grade credit ratings; 

• 

• 

the Board’s flexible dividend policy; 

the principal risks and uncertainties facing the Company and the mitigating controls, as described in the 

the NWL Annual Report and Financial Statements for the year ended 31 March 2022, which are monitored 

by the Audit Committee, R&CSC and Board; and 

• 

the work of the Audit Committee, on behalf of the Board, to review and approve the baseline plan and 

stress  test  scenarios  and  to  review  the  outputs  of  the  stress  testing  in  the  context  of  the  Company’s 

financial resilience. 

To support the Directors in their assessment of viability, the Audit Committee carried out a thorough review process. 

This included discussing and approving appropriate updates to the Board approved plan to reflect latest economic 

projections, in particular inflation assumptions and discussing an appropriate forward testing period. This concluded 

that  the  base  forward  plan  should  be  updated  to  reflect  the  latest  inflation  forecast  published  by  the  Bank  Of 

England’s Monetary Policy Committee in May 2022. 

The Audit Committee also discussed and approved the range and severity of stress test scenarios to be applied to 

the baseline plan, taking account of the principal risks of the business. The stress tests are set out in detail below. 

The Audit Committee then reviewed the detailed outcomes of the stress testing and the potential impact on the 

Company’s key financial ratios and discussed appropriate mitigating actions which could be taken if the need arose. 

Following this process, the Audit Committee recommended approval of the viability statement to the Board. 

The Directors have chosen a period of eight years to March 2030 to assess the viability of the Company to align 

with the business planning process for the regulatory price review period to March 2025, and the next price review 

period to March 2030. Whilst the Directors do not believe that it is possible to test financial resilience beyond March 

2025  to  the  same  level  of  robust  detail,  given  uncertainty  of  revenue  and  returns  past  this  point,  they  have 

performed an assessment of viability beyond the current price control period against an extended plan applying 

reasonable assumptions for the next price review which includes a sufficient rate of return to enable the Company 

to finance its functions.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

The  financial  forecast  has  been  stress  tested  under  a  number  of  plausible  and  severe  adverse  scenarios.  The 

scenarios were selected after considering the principal risks and uncertainties facing the Company and the key 

economic and financial variables which could impact on the forecast. The combined impact of multiple scenarios 

has also been tested. 

The  stress  tests  were  assessed  in  the  context  of  NWL’s  overarching  financial  objective  of  maintaining  prudent 

investment grade credit ratings from S&P and Moody’s, and the Board’s target of retaining regulatory gearing of 

around 70%. Whilst the viability statement relates specifically to NWL, both rating agencies take account of NWGL 

metrics  in  their  methodologies,  therefore,  the  impact  on  both  NWL  and  NWGL  financial  plans  have  been 

considered. 

The table below sets out the stress tests performed, the severity of the adverse scenarios applied, the outcome in 

the context of the key financial ratios and potential mitigating actions where required.

The baseline plan is compatible with retaining the Company’s investment grade credit ratings. None of the stress 

test scenarios undermined the Company’s long term financial resilience. However, certain stress test scenarios 

indicated  a  risk  of  a  credit  rating  downgrade,  specifically  higher  operating  and  capital  costs  and  a  substantial 

increase  in  the  cost  of  raising  new  finance  into  AMP8.  However,  in  the  Board’s  opinion,  even  the  most  severe 

scenarios were not indicative of falling below BBB/Baa2 rating. 

To  the  extent  that  any  of  these  scenarios,  in  isolation  or  combination,  would  place  retention  of  the  Company’s 

investment grade credit rating or liquidity position at risk, the  Board would seek to take mitigating actions. This 

includes: 

• 

• 

• 

actions to support pension deficit repair payments utilising an asset-backed funding arrangement; 

flexible and efficient financing of new debt; 

strong management of costs and delivering efficiencies through innovation, taking care not to impact on 

service levels to customers; and 

• 

application of the Board’s flexible dividend policy. 

While outperformance of the FD cost allowance would also help mitigate such an outcome, the Directors do not 

consider this to be a key mitigating factor given the level of challenge and stretch implied by the FD. 

The Board engaged Deloitte LLP to provide third party assurance, in the form of agreed upon procedures.

BOARD STATEMENT ON ACCURACY AND COMPLETENESS OF DATA AND 
INFORMATION 

In  the  opinion  of  the  Board,  based  on  the  governance  and  assurance  arrangements  in  place,  the  data  and 

information contained in this Annual Performance Report and provided to Ofwat during the year is complete and 

has a high degree of accuracy.  Our Data Assurance Summary provides a detailed review of the assurance work 

carried out in the year and the findings of our assurance providers, upon which this opinion is based.  

Governance Arrangements & Assurance Framework 

The Board is committed to providing regulatory data and information that is accurate, clear and transparent in order 

to  maintain  the  trust  of  our  customers  and  stakeholders.    The  Board  takes  ownership  of  the  arrangements  for 

governance and assurance of regulatory submissions and reporting.  This is monitored and controlled through the 

Board’s Audit Committee and Risk & Compliance Sub-committee, which report regularly to the Board. 

The Board has put in place a comprehensive assurance framework, shown in the diagram below.  This has Board 

oversight  at  its  core,  supported  by  a  risk  management  framework  and  multiple  layers  of  internal  and  external 

assurance. 

The Risk & Compliance Sub-committee, on behalf of the Board, carried out its annual review of the effectiveness 

of the Company’s risk management and internal control systems. This review confirmed that the Company has 

strong systems of internal control and robust processes in place to enable it to identify, evaluate and manage the 

risks  it  faces  and  to  ensure  that  its  obligations  are  met.  These  systems  and  processes  are  embedded  in  the 

organisation  and  are  reviewed  regularly  by  the  Board,  its  Committees  and  Sub-committee.  The  annual  review 

confirmed that the risk management and internal control systems have operated effectively through the year and 

that there have been no significant failings or weaknesses.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

Activities in the Year 

We published our annual Assurance Plan in March 2022, following consultation with customers and stakeholders, 

which set out how we intend to meet our obligations and the commitments we made to customers and stakeholders 

in our Business Plan 2020-25 and how we provide information of appropriate quality.   

In  developing  this  Assurance  Plan  we  thoroughly  reviewed  our  risks,  strengths  and  weaknesses  against  the 

stretching commitments in our Business Plan, identifying which areas required increased focus to ensure quality 

of reporting. 

The Board, through the work of its Audit Committee, has overseen a plan to improve regulatory data through the 

year.  This plan was designed to address areas of risk identified in reports from our assurance providers for the 

2020/21 APR, as well as areas where the source of data has changed during the year and where there are new 

reporting requirements.  This included: 

• 

conflicting  data  being  received  from  field  activities  (eg  notes  and  job  types  not  matching)  which 

necessitated significant manual review and correction; 

• 

• 

• 

asset information held outside of corporate systems in spreadsheet form; 

improving accuracy in the use of complex spreadsheets; and 

streamlining business process for reporting bioresources data. 

As part of the approval process for this APR, the Audit Committee received assurance reports from the Internal 

Audit manager, the external technical assurer,  PricewaterhouseCoopers LLP, and the financial auditor, Deloitte 

LLP.  We have also published a Data Assurance Summary as part of our suite of annual reporting.  This describes 

the assurance activities carried out throughout the year and for data provided in the APR, and reports any key 

findings of our assurance providers.  This confirms there were no significant issues to report. 

Conclusion 

The Board is satisfied that the governance and assurance arrangements it has put in place are comprehensive and 

robust  and  have  operated  effectively  throughout  the  year.    On  this  basis,  the  Board  is  confident  that  the  data 

reported has a high degree of accuracy.  However, no assurance process can give an absolute guarantee of total 

accuracy, especially given the extremely large volume of data in the APR and the fact that some of the reported 

information is dependent on expert judgement and assumptions, for example accounting separation data.

STATEMENT ON RUSSIA SANCTIONS REGULATIONS 

At Northumbrian Water Limited we are committed to ensuring  compliance with all applicable legislation in force 

from time to time both within our own business and within our extensive supply chain. As such, we have set out 

below  the  steps  we  have  taken,  and  will  continue  to  take,  in  relation  to  ensuring  compliance  with  ‘The  Russia 

(Sanctions) (EU Exit) Regulations 2019 (as amended)’ (the “Regulations”). 

•  Having conducted a review of our Tier 1 supply chain, we consider that there is a very low risk of non-

compliance with the Regulations within Tier 1 of our supply chain. 

•  We  have  contacted  all  strategic  Tier  1  chemical  suppliers  asking  them  to  confirm  any  connection  to 

Russia,  specifically  with  regards  to  any  Russian  entities  or  individuals  subject  to  sanctions  under  the 

Regulations. Only one such supplier informed us that they had an operational site within Russia, but they 

confirmed to us that the site had now been shut down. 

•  Our standard contracts/terms and conditions include a contractual obligation on all suppliers to ensure 

that they comply with all applicable statutes, regulations, byelaws and other legal requirements in force 

from time to time. 

•  We will continue to monitor our supply chain and our investors (both debt and equity, including ultimate 

controllers of the regulated company) to ensure their continued compliance with the Regulations.  

• 

In addition, we do not engage with any known restricted or sanctioned entities in any form of financial or 

transactional services in relation to our debt portfolio and in relation to the applicable laws and regulations, 

including but not limited to the Regulations, that prohibit such activity. 

•  Our  commercial  banking  and  financing  relations  consist  only  of  banking  groups  governed  by  the  UK 

Financial  Regulation  Authorities  and,  alongside  their  strict  compliance  requirements,  we  would  further 

provide support and assistance for any of our direct or indirect transactions that give rise to any knowledge 

or suspicions of any breaches of the Regulations or of any other applicable financial sanctions. 

•  We confirm that we have no transactions with any of the Russian banks subject to current sanctions under 

the Regulations or banned from SWIFT messaging.

FOR YEAR ENDED 31 MARCH 2022 

REGULATORY ACCOUNTING POLICIES AND DISCLOSURES 
for the year ended 31 March 2022 

(a)  Regulatory Accounts - Basis of Accounting 

The Regulatory Accounting Statements, on pages 125 to 177 of the APR, have been prepared in accordance 

with  the  Regulatory  Accounting  Guidelines  (RAGs)  issued  by  Ofwat.  They  have  been  prepared  on  a 

consistent basis to the Company’s Financial Statements, with the following exceptions: 

• 

income relating to energy generation and meter reading, which is recorded as revenue in the statutory 

accounts, has been recorded as negative operating expenditure; 

• 

rental income and amortisation of deferred capital income, which are recorded as revenue in the statutory 

accounts, have been recorded as other income below operating profit; 

• 

profit on disposal of fixed assets, which is recorded as operating costs in the statutory accounts, has been 

recorded as other operating income; 

• 

borrowing  costs  that  are  directly  attributable  to  the  acquisition  or  construction  of  an  asset,  which  are 

capitalised in the statutory accounts, are charged to the income statement; and 

• 

the prior year provision for innovation fund costs in the Statutory Financial Statements has been reversed 

in the Regulatory Accounting Statements, in accordance with Ofwat guidance in IN 22/01 Expectations 

for monopoly company annual performance reporting 2021-22. 

The information reported in the Regulatory Accounting Statements relates to NWL’s Appointed business only, 

except where stated. The Appointed business comprises Regulated Activities, defined in Condition A of the 

Licence  to  be  ‘functions  of’  and  the  ‘duties  imposed  on’  a  water  and  sewerage  undertaker  by  the  Water 

Industry Act 1991. Such duties are consequently those necessary for the Company to fulfil its duty as a water 

and sewerage undertaker. 

The  accounts  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. 

(b)  Revenue recognition  

The revenue recognition policy is the same in the regulatory and statutory accounts, other than the exceptions 

related  to  income  from  energy  generation,  meter  reading,  rental  income  and  deferred  capital  income,  as 

explained above. 

RAG 1.09 requires companies to recognise all revenue billed to properties which receive a service, other than 

if confirmed as void, and to assume that it is probable that this will be collected, disapplying IFRS 15 in this 

respect. NWL complies with this requirement. 

Revenue  from  water  and  sewerage  charges  billed  to  customers  is  recognised  pro-rata  over  the  period  to 

which it related. For consumption by measured customers which has not yet been billed, revenue is estimated 

and accrued using a defined methodology based upon historical usage and the relevant tariff per customer. 

15 July 2022 
PAGE 137 OF 206 

 
 
 
 
 
NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

Invoices raised or payments received where the service has not been provided are not recognised in revenue 

in the year but are treated as receipts in advance. 

Additional charges added to a customer’s account as a result of debt recovery activity, such as court costs or 

solicitors’ fees, are recognised as negative operating costs when payment is received in both the statutory 

and regulatory accounts. They are not recognised in revenue. 

Charges for water and sewerage services remain due in full whilst a property contains furnishings and fittings 

or when a property is unfurnished and water is being used for  any purpose including refurbishment. If the 

Company has turned off the supply of water at the mains to a property at a customer’s request, then water 

supply charges are not payable. 

If the supply of water is turned off and the property is unfurnished the property is considered unoccupied and 

charges are not payable. If, however, the supply of water is turned off and the property remains furnished it 

is considered ready for occupation and in this case sewerage charges in respect of the drainage of surface 

water and contribution to highway drainage continue to be payable. 

If a property is recorded as empty in the billing system an empty property process is followed. The purpose 

of this process is to verify whether the property is occupied or not and, if occupied, to identify the chargeable 

person and raise a bill.  No bills are raised in the name of ‘the occupier’. 

The empty property process comprises a number of steps including an initial letter asking the occupier to 

either contact the Company or return a completed registration form, a check of the property record against 

Land Registry information and visits to the property by Company representatives. If these steps confirm that 

a property appears to be empty, then the supply may be turned off. 

New properties are charged from the date a meter is installed, if consumption is being recorded on the meter. 

If the property is unoccupied but water is being registered, the developer will be charged.  Once the developer 

is no longer responsible for a property, if no new occupier has been identified the property will be treated as 

unoccupied and the empty property process followed, as outlined above. 

A  retrospective  review  has  confirmed  that  the  measured  household  income  accrual  at  31  March  2021  of 

£57.9m was marginally higher than the amounts subsequently billed to customers of £55.8m. 

(c)  Bad debt policy  

The policy for bad and doubtful debts is applied consistently between the statutory and regulatory accounts. 

(i)  Bad debt write offs 

Debt is only written off after all available economic options for collecting the debt have been exhausted and 

the debt has been deemed to be uncollectable. This may be because the debt is considered to be impossible, 

impractical, inefficient or uneconomic to collect. 

Situations where this may arise and where debt may be written off are as follows: 

•  where the customer has absconded without paying and strategies to trace their whereabouts and collect 

outstanding monies have been fully exhausted; 

15 July 2022 
PAGE 138 OF 206 

 
 
 
 
NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

•  where the customer has died without leaving an estate or has left an insufficient estate on which to levy 

execution; 

•  where the customer does not have any assets or has insufficient assets on which to levy execution; 

•  where the value of the debt makes it uneconomic to pursue; 

•  where county court proceedings and attempts to recover the debt by debt collection agencies have proved 

unsuccessful; and 

•  where the customer has been declared bankrupt, is in liquidation or is subject to insolvency proceedings 

or a debt relief order and no dividend has been or is likely to be received. 

For debt to be written off there must be a legitimate charge against the debtor. If it is considered that part or 

all of the debt is incorrect or unsubstantiated, then such elements are dealt with through the issue of a credit 

note.  

(ii)  Bad debt provisioning  

The Company’s detailed bad and doubtful debts provision policy has remained unchanged during the year 

and  has  been  consistently  applied  in  the  current  and  prior  periods.  The  bad  debt  provision  is  charged  to 

operating costs to reflect the Company’s assessment of the risk of non recoverability of debtors. It is calculated 

by applying expected recovery rates to debts outstanding at the end of the accounting period. These recovery 

rates take into account the age of the debt, payment history and type of debt. 

Higher provisioning percentages are applied to categories of debt which are considered to be of greater risk, 

including those with a poor payment history as well as to those of greater age. Bad debt provisioning rates 

are reviewed annually to reflect the latest collection performance data from the Company’s billing system. 

Actual amounts recovered may differ from the estimated levels of recovery which could impact on operating 

results. A comparison of the provision against historical collection rates is carried out at the end of each year 

to validate and, if necessary, adjust the level of provision. 

An  assessment  of  the  potential  impact  of  Covid-19  on  the  economic  circumstances  of  our  household 

customers was made at 31 March 2020 and a provision of £6.5m created, which was retained at 31 March 

2021. Cash collection has remained in line with expectations during the pandemic, therefore management 

has concluded that this provision is no longer required and it has been released at 31 March 2022. 

Household  customers  are  facing  significant  cost  of  living  pressures  caused  by  high  energy  costs  and  the 

consequent inflationary pressures on food, fuel and other household costs. An assessment has been made 

of the risk to collection, which has considered the increase in debt experienced during the financial crisis in 

2008, and an additional provision of £2m has been created. 

The  provision  has  reduced  from  £111m  at  31  March  2021  to  £92.4m  at  31  March  2022,  reflecting  cash

(d)  Capitalisation policy 

The policy for the capitalisation of costs as items of property, plant and equipment and intangible assets is 

applied consistently between the statutory and regulatory accounts, in accordance with IAS 16 Property, Plant 

and Equipment and IAS 38 Intangible Assets. 

The application of this policy is summarised below. Further detail is provided in the accounting separation 

methodology statement published on our websites. 

The cost of construction or purchase of new or replacement  infrastructure and non-infrastructure assets is 

capitalised.  Cost  includes  any  costs  directly  attributable  to  bringing  the  asset  into  condition  for  use  in  the 

business, including directly attributable overhead costs but excluding general overhead costs. The costs of 

infrastructure and non-infrastructure assets are depreciated over their useful economic lives. 

On the infrastructure network, capital replacement of assets includes any renewal of a full pipe length of main 

or sewer and replacement of ancillaries such as stop taps, valves, meter chambers and manhole covers. 

Subsequent maintenance expenditure is treated as an operating cost unless it provides an enhancement of 

economic benefits in excess of the expected standard of performance such as an extension in the estimated 

useful life or an increase in capacity, in which case it is capitalised. Examples of maintenance costs charged 

as operating costs include pipe and tank cleaning, inspections, surveys and zonal studies. 

The Company has reviewed its Intangible Assets following publication of IFRIC guidance to IAS 38 Intangible 

Assets regarding ‘Customer’s Right to Receive Access to the Supplier’s Software Hosted on the Cloud’ and 

‘Configuration or Customisation Costs in a Cloud Computing Arrangement’. As a result, costs of configuring 

and implementing ‘software-as-a-service’ systems, where the Company does not control the asset, are now 

expensed  to  the  income  statement  in  the  year  in  which  they  are  incurred.  These  costs  were  previously 

capitalised and classified as intangible assets. This change has been applied retrospectively. The impact of 

the change is set out in note 27 of the NWL Annual Report and Financial Statements for the year ended 31 

March 2022. 

(e)  Accounting separation policy 

Cost allocations have been prepared in accordance with RAG 2.08 and RAG 4.10 for the definitions for the 

regulatory accounting tables. All costs are recorded in the accounting records by cost centre. Cost centres 

are  defined  either  as  a  direct  department,  comprising  operational  and  customer  functions,  or  a  support 

department. Direct departments are mostly directly allocated to service activities based on the nature of the 

function,  although  some  costs  require  apportionment  on  an  appropriate  basis.  Support  departments  are 

apportioned across the price controls either based upon a specific analysis of the costs or by apportionment 

by an appropriate cost driver. Once allocated to the appropriate price control the costs are then allocated to 

service activities pro-rata to full time equivalent staff numbers of the direct departments. 

Fixed assets directly involved in the activities within each business unit are recorded against that business 

unit using direct allocation per the location or asset type. Where an asset is utilised in more than one business 

unit, the asset is allocated to the business unit of principal use and costs are recharged to other different 

business units on the same basis used to allocate operating expenditure. 

Further detail is provided in the accounting separation methodology statement published on our website.

Differences between Statutory and Regulatory Definitions 

Differences between statutory and RAG definitions are explained in note (a) of the Regulatory Accounting Policies and Disclosures. 

The differences which result in a change to profit for the year reflect the following accounting treatments: 

• 

capitalisation of borrowing costs, which are capitalised in the  Statutory Financial Statements but charged to the Income 

Statement in the Regulatory Accounting Statements, along with the associated depreciation and deferred tax; and  

• 

Innovation  Fund  costs,  which  are  provided  in  the  Statutory  Financial  Statements  but  removed  from  the  Regulatory 

Accounting Statements, along with the associated tax. 

Other changes are presentational in nature: 

• 

income relating to energy generation and meter reading has been reclassified from revenue in the statutory accounts to 

negative operating costs; 

• 

rental income, amortisation of deferred income and other contributions to capital investment have been reclassified from 

revenue in the statutory accounts to other income; and 

• 

profit on disposal of fixed assets has been reclassified from operating costs in the statutory accounts to other operating 

income.

Differences Between Statutory and Regulatory Definitions 

Differences between statutory and RAG definitions are explained in note (a) of the Regulatory Accounting Policies and Disclosures. 

The change in net assets and total equity reflects the different treatment of borrowing costs, which are capitalised in the Statutory 

Financial  Statements  but  charged  to  the  income  statement  in  the  Regulatory  Accounting  Statements,  along  with  the  associated 

depreciation and deferred tax; and the removal of the provision for Innovation Fund costs from the Regulatory Accounts along with 

the associated tax. Other changes reflect the disaggregation of cash balances and trading balances between the appointed and non-

appointed businesses.

Explanation of Financial Flows 

The purpose of this table is to provide transparency of financial flows to investors, comparing actual flows, and the main elements of performance which contribute to these flows, against the 

financial flows assumed by Ofwat under the notional structure at the last price review. 

The table shows performance for 2021/22 and cumulative performance for the first two years of the 2020-2025 price control period. All of the financial values are expressed in the same 2017/18 

price base as the PR19 price review. The commentary below focuses on 2021/22 performance except where stated. 

Return on regulatory equity (RORE) 

At PR19, the base notional RORE was set at 4.40% for 2021/22. The regulatory equity base represents the proportion of RCV funded as equity rather than debt. Ofwat’s notional structure for 

PR19 assumed net debt at 60% of RCV, equating to base regulatory equity of 40%, or £1,619m at March 2022. 

NWL’s actual average gearing in 2021/22 was 69.6%, due to having higher net debt than assumed by Ofwat’s notional structure, resulting in actual regulatory equity of 30.4% of RCV, or £1,224m. 

On the Company’s actual structure, this equated to a base return of £53.8m.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

Explanation of Financial Flows (continued) 

Financing 

This section of the report relates to performance from financing, excluding tax. 

Gearing is calculated as net debt divided by RCV. NWL’s average gearing was 69.6%, remaining above Ofwat’s notional structure 

assumption of 60% but below our target level of around 70%. The more efficient capital structure has generated a financing benefit 

of £17.1m. The CMA redetermination removed the gearing sharing mechanism for NWL, though it would not have come into effect 

during the year if it had been applied. 

Corporation tax reports the difference current tax funded in the FD and the actual tax rate applied to profit before fair value, adjusted 

for capital allowances. This has shown an outperformance of £15.6m in 2021/22, due to a combination of lower taxable profits and 

accelerated ‘super deductions’ on capital investment. A reconciliation of our current tax to FD allowance is provided on page 155. 

All tax losses acquired from related parties in the year were paid for in full. 

Cost of debt performance is reported in real terms, rather than nominal. As reported in table 4H, 60% of the Company’s debt is at 

fixed rate and not impacted by indexation. In 2021/22, the real cost of debt was 1.39% lower than allowed in the FD due to relatively 

high CPIH inflation, generating a £39m outperformance on cost of debt. 

Hedging instruments shows the impact of interest rate swaps on the cost of debt reported in the year, and equated to a negative 

return of cost of £33.4m in the year. This reflected adverse mark to market movements on inflation-linked swaps which will reverse 

over the remaining term of the instruments. 

The net effect of financing and tax in the year was an outperformance of FD allowance by £38.3m, or 3.12% of actual regulatory 

equity. 

Operational Performance 

This section of the report explains the impact of operational performance on wholesale totex, ODIs and retail costs, each of which is 

explained elsewhere in this report. 

Wholesale totex performance reflects the performance presented in table 4C, and excludes variations due to timing of expenditure. 

The  underperformance  of  £11.9m  reflects  overspends  on  each  price  control,  other  than  bioresources.  As  explained  in  the 

commentary  to  table  4C  on  page  190,  this  primarily  relates  to  higher  operating  costs  caused  by  the  unprecedented  increase  in 

energy costs during the year. 

ODI performance against our PCs is reported in the tables in section 3, with table 3H reporting the summary incentive rewards and 

penalties (excluding C-MeX and D-MeX explained below). The reported performance for the year for in-period adjustments is a net 

penalty of £19.9m. This includes the full impact of Storm Arwen on interruptions to supply however, as explained on page [X], we 

have  made  a  representation  to  Ofwat  for  an  exemption  in  respect  of  Storm  Arwen,  as  it  was  declared  a  civil  emergency.  If  our 

representation is accepted in full then the ODI performance would improve by £22.4m to a net reward of £2.5m in the year. Our 

performance against each ODI is explained earlier in this report. 

Performance rewards on C-MeX and D-Mex are based on comparative performance across the sector and are not  finalised until 

later in the year. For the purposes of this table, the performance is reported a year in arrears so the rewards of £2.9m for C-MeX and 

£0.4m for D-MeX relate to 2020/21 performance. Our performance has improved on both measures therefore we would expect to 

earn a larger reward for 2021/22 which will be reported in next year’s APR. 

Retail  costs  were  higher  than  the  PR19  allowance  by  £11.7m,  as  explained  in  the  narrative  to  table  2C  and  due  in  part  to  the 

allowance not being increased each year for inflation.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

Exceptional items of £0.4m reflects the company’s share of benefits from the disposal of surplus land and properties. 

The net effect of operational performance in the year was an underperformance of FD allowance by £39.8m, 3.25% of regulatory 

equity, though this would reduce by more than half if our representation on Storm Arwen is accepted in full. 

Total Shareholder Return 

The  total  shareholder  return  comprises  base  RORE,  financing  performance,  operational  performance  and  growth  in  the  RCV  as 

allowed  in  the  FD.  Our  total  shareholder  return  of  £141.1m  performance  comprises  £52.3m  RORE  and  £88.8m  growth  in  RCV, 

reflecting the high levels of inflation in the latter part of the year. 

Retained Value 

Our dividend policy is set out on page 175 and we explain how this dividend policy is applied on pages 175 to 176. This explains 

that we paid no dividends between April 2019 and April 2021, reflecting the impact of the PR19 FD and the uncertainty surrounding 

the CMA redetermination process and the Covid-19 pandemic. A final dividend for the year ended 31 March 2021 was paid during 

2021/22 which reflected cumulative financial performance over the previous two years, including the final year of the previous price 

review period. 

It is therefore more appropriate to consider dividends and retained value on a cumulative basis.  For the price control period to date, 

gross dividends of £83.6m have been paid, including amounts related to the previous price control period. The average shareholder 

return for the price control is £94.0m, generating a retained value of £10.4m. 

Return on Regulatory Equity 

This commentary explains the differences between the base return at PR19 and actual return. 

The FD RORE for 2021/22 was 4.40%. Actual returns on actual regulatory equity for 2021/22 were 4.27%, an underperformance of 

0.13%.  The reasons of this variance have been explained in the commentary above, but are summarized below. 

Financing outperformance was 3.12%, due largely to the benefit of having gearing above the notional structure (1.39%), lower current 

tax as a result of lower profits and accelerated super deductions (1.28%) and the impacts of higher inflation on the cost of debt in 

real terms (3.19%), partially offset by the impact of high inflation on hedging instruments (-2.73%). For the real cost of debt, 57% of 

our debt is fixed rate and does not vary with inflation, therefore when inflation is comparatively high, the real cost of debt appears 

lower. 

Operational  underperformance  was  -3.25%,  due  to  wholesale totex  performance  which  was  heavily  impacted  by  energy  costs  (-

0.98%), a net ODI underperformance caused primarily by interruptions to supply during Storm Arwen for which we have made a 

representation to Ofwat to exclude as it related to a civil emergency (-1.62%), and inflationary pressures on retail costs (-0.96%). 

These are partially offset by positive C-MeX and D-MeX performance in 2020/21 (0.27%) and proceeds from the disposal of surplus 

land (0.04%).

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

APPOINTED BUSINESS TAXATION 

The rate of UK corporation tax for the current year was 19%. The Company's deferred tax liabilities have been restated from 19% to 

25%, in response to Finance Act 2021 which provides for an increase in the tax rate with effect from 1 April 2023. The movement in 

the year has been calculated at the higher rate. 

Current tax for the Appointed business is derived by adjusting the Company's statutory position by the amount relating to the activities 

of the Non-appointed business. The Appointed business credit for the year of £8.4m includes £7.6m relating to a carry back of tax 

losses, £0.7m payable for UK:UK transfer pricing items, £0.7m receivable from the Non-appointed business in respect of tax losses 

that will be surrendered by the Appointed business, and £0.8m receivable from fellow group companies for similar loss surrenders. 

The surrenders have not required the disclaimer of any capital allowances by the Appointed Business and payments for the losses 

will be made at the full rate of corporation tax. 

The prior years' corporation tax credit of £1.7m reflects revisions to tax reliefs for capital expenditure and R&D claims made. 

The current corporation tax credit of £8.4m reflects a swing of £20.0m compared to the charge of £11.6m in 2020/21 and is explained 

by the decrease in profit before tax and fair value movements (-£7.4m), additional tax reliefs for capital expenditure (notably super 

deductions) (-£12.6m), deductions for previous provisions (-£2.5m), a one off deduction on the change of basis of accounting for 

'software as a service' (-£4.2m), tax losses (+£6.1m), and other small variances (+£0.6m). 

The deferred tax charge for the Appointed business is derived by adjusting the Company's statutory charge (£171.7m) by amounts 

relating to accounting differences (i.e. capitalised interest: charge of £5.1m; Innovation Fund: credit £0.6m) and the activities of the 

Non-appointed business (charge of £1.2m).  The Appointed business charge of £166.0m includes £153.4m in relation to the rate 

restatement, £5.4m for the current year, £4.2m relating to SaaS and £3.0m for prior years related to the matters referred to above.  

Deferred tax in the year and at the balance sheet date is all provided at 25%, being the rate at which temporary differences  are 

expected to reverse. 

An  explanation  of  why  the  current  tax  credit  for  the  Appointed  business  is  lower  than  the  result  of  applying  the  standard  rate  of 

corporation tax to profit before tax is provided in the table opposite:

The Company expects to continue to incur high levels of capital expenditure during the remainder of the 2020-25 regulatory review 

period which should result in claims for tax reliefs in excess of depreciation. 

In particular, the temporary increase in the rate of capital allowances provided in Finance Act 2021 that commenced in the current 

year  will  also  apply  to  qualifying  expenditure  incurred  in  the  year  ended  31  March  2023.  This  will  attract  allowances  of  130% 

(compared to the normal 18%) in the case of assets with an economic life of less than 25 years, and 50% (compared to the normal 

6%) in the case of assets with an economic life of 25 years or more.

FOR YEAR ENDED 31 MARCH 2022 

CURRENT TAX RECONCILIATION TO FD 

An allowance for corporation tax was made in the Final Determination (FD) at PR19.  Actual performance differs to the FD for a 

number of reasons.  As far as current tax is concerned, the charge for the year is reconciled to the FD allowance as follows: 

Current tax charge (at 19%) allowed in price limits 
Net decrease in profit before tax and depreciation 
Increase in allowable pension contributions 
Increase in tax reliefs for capital expenditure 
Increase in capital allowances due to 'super deductions' 
Decrease in amortisation of grants and contributions 
Decrease in provisions 
Increase in service income taxed via capital allowances 
Change in accounting basis for 'software as a service' 
Other 
Tax losses arising in the year 
Credit arising from carry back of tax losses 
Adjustment in respect of prior years

The Company is required, by section 3.30 of RAG 3.13, to publish details of its Tax Strategy relating to the Appointed Business within 

the Annual Performance Report.  For the avoidance of doubt, the Company has a single Tax Strategy which applies to its Appointed 

and Non-appointed businesses, as well as to its subsidiaries. 

The Tax Strategy set out below is for the Company’s financial year ended 31 March 2022 in order to satisfy the requirements of 

Schedule 19, Finance Act 2016. 

Aim 

The Company is committed to fully complying with all its statutory tax obligations, including the payment and recovery of taxes at the 

right time and the provision of all relevant information to HM Revenue and Customs (HMRC) to support the amounts of tax concerned. 

The Company’s Board owns and approves the Tax Strategy which comprises the following four components: 

a) Tax governance arrangements 

The Board reviews and approves all significant investment and business operating decisions directly or delegates the appropriate 

authority.  The Company’s Audit Committee considers significant tax related matters as part of its monitoring of internal controls and 

financial reporting arrangements.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

Day-to-day management of the Company’s tax affairs is delegated to the Tax Manager and to other appropriately qualified staff who 

have responsibility for specific taxes.  All staff with responsibility for tax report to members of the Company’s senior management 

team which, in turn, reports to the Board. 

The Company's tax affairs are conducted in a business-like manner in accordance with the Company's commitment to corporate 

responsibility. 

b) Tax risk management framework 

The Company’s Risk Committee oversees the risk assessment process applied by the business which includes an assessment of 

tax risks.  Significant risks identified by the business are escalated for the Committee to consider. 

As far as possible, through the activities of its Board, Committees and personnel responsible for tax matters, the Company seeks to 

reduce or eliminate the level of tax risk arising from its operations by ensuring appropriate processes and controls are in place. 

The Company only takes tax positions which are justifiable and based on law, with advice taken from reputable professional firms 

where  necessary.    In  accordance  with  internal  governance  procedures,  any  transaction  that  is  likely  to  have  material  tax 

consequences must be referred to the Board. 

To help manage tax risk, the Company’s taxation affairs are only handled by appropriately qualified and experienced staff and, where 

necessary, training is given to non-tax staff who are involved in processes which have tax implications. 

The  Company  does  not  tolerate  or  condone  any  form  of  tax  evasion,  whether  committed  or  facilitated  by  its  own  staff  or  any 

associated persons (e.g. agents and other persons who perform services for or on behalf of the Company) and manages this risk by 

the use of appropriate processes. 

c) Approach to tax planning 

The  Company  considers  tax  as  part  of  its  business  decision  making  process.    When  entering  into  commercial  transactions,  the 

Company seeks to obtain the benefit of tax incentives, reliefs and exemptions available under UK tax legislation, consistent with the 

purpose and the letter of the law. 

The tax affairs of the Company are arranged and managed in response to, and in support of, its business or commercial activities.  

Related party transactions are managed and documented to ensure they are in compliance with local tax law and practice. 

d) Relationship with HMRC 

The Company seeks to have a transparent and constructive relationship with HMRC on all taxation matters and keeps HMRC aware 

of significant transactions and business developments.  All contact with HMRC is conducted in a professional and courteous manner. 

The Company seeks to obtain certainty from HMRC at the earliest opportunity on the tax treatment of complex or uncertain issues.  

Discussions  with  HMRC  are  held  at  least  annually  to  review  past  and  present  tax  risks  and  agree  on  the  steps  required  to  take 

matters forward.  Resolution of any disputed matters will be sought through open discussion and negotiation with HMRC, but the 

Company is prepared to litigate in cases where it believes the technical basis of a decision is incorrect. 

The Company takes an active role in the development of the UK’s legislative framework through participation at company or industry 

level in Government consultations on significant new tax laws.

Household retail revenue, reported in table 2I, was £56.0m, which was £0.5m higher than allowed in the FD. 

Household retail costs excluding pension deficit repair costs, in table 2C above, were £54.9m, which was £5.9m higher than allowed 

in the FD, giving rise to a margin of 2%. 

The operating costs are £9m lower than 2020/21, due mainly to a reduction in the bad debt provision. This includes the release of 

the £6.5m provision created for Covid-19 risk charge which is no longer required due to cash collection remaining strong throughout 

the pandemic. The retail cost base is higher than the allowance in the FD, reflecting inflationary pressures on staff and other costs 

which were not allowed in the FD.

NON-HOUSEHOLD WATER AND WASTEWATER REVENUES BY TARIFF TYPE 

NWL exited the NHH retail market at 1 April 2017 and transferred its NHH retail business to an acquiring licenced retailer, NWGB, 

another subsidiary of NWGL. 

In accordance with RAG 4.10, as NWL has exited all NHH market activities, we are no longer required to publish tables 2G and 2H. 

NWL still provides wholesale water and wastewater services to NHH properties in our areas of supply. The NHH wholesale revenue 

for the year ended 31 March 2022 was £135.0m, as reported in table 2I.

2I  REVENUE ANALYSIS for the 12 months ended 31 March 2022 (continued) 

Wholesale revenue control reconciliation to FD 

Charges for 2021/22 were set in accordance with the price controls set by Ofwat in its PR19 Final Determination. The changes to 

allowances resulting from the CMA redetermination take effect in price controls from 2022/23. 

During the COVID-19 pandemic we have seen an increase in household consumption due to the impact of various lockdown periods 

and customers working from home. This increased consumption has continued during the year. Various initiatives have continued 

during the year which have led to a reduction in the number of household voids to a rate of 3.53% at the year end. 

For  our  non-household  charging  base,  during  the  year  we  have  seen  consumption  broadly  in  line  with  anticipated  levels.   Non-

household voids have remained relatively stable. 

Wholesale water revenue in 2021/22 was £5.1m (1.2%) higher than the revenue cap income allowance. This is split between the 

resources and network+ price controls which were £8.3m (10.2%) higher and £3.2m (1.0%) lower than revenue cap respectively. 

Within the network+ price control, grants and contributions income was £6.7m (32%) lower than the allowed revenue for the period, 

this is partly due to the impact of COVID-19 pandemic which has slowed down construction.  

Wholesale wastewater revenue in 2021/22 was £1.0m (0.4%) lower than the revenue cap income allowance.  This is split between 

the network+ and bioresources price controls which were £1.3m (0.6%) higher and £2.3m (10.6%) lower respectively.  Within the 

network+ price control, grants and contributions income is £1.2m (31.9%) lower than the allowed revenue for the period, this is partly 

due to the impact of COVID-19 pandemic which has slowed down construction.  

The revenue imbalances in the table above (for water resources and the network+ controls) will be incorporated into the Revenue 

Forecasting Incentive model and will be adjusted within charges for 2023/24 against the relevant price controls.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

Reconciliation of infrastructure charges and network reinforcement costs 

Infrastructure charges are set at a level to fund investment in reinforcement of our networks, to meet the demand arising from new 

development of household properties. We are required to ensure that revenue from infrastructure charges broadly matches network 

reinforcement expenditure over a five year rolling period. 

We review infrastructure charges annually, taking account of extra capacity expected to be required as a result of new developments 

in  the  following  five  years.  Our  forecast  reflects  applications  received  for  the  provision  of  new  infrastructure,  pre-development 

enquiries and a longer term view of local authority plans and strategic studies. 

Water 

During  2021/22,  expenditure  on  water  network  reinforcement  projects  was  greater  than  infrastructure  charges  receipts.  The  net 

position  at  the  end  of  2021/22  was  that  the  cumulative  expenditure  on  water  network  reinforcement  is  £3.5m  less  than  the 

infrastructure charge income received (2020/21: £5.2m). The projected network reinforcement expenditure over the next five years 

has  been  reassessed  and  is  expected  to  be  significant  to  support  new  development  growth.  Our  plan  is  to  increase  water 

infrastructure charges to fund the next five year’s reinforcement expenditure whilst accounting for the £3.5m surplus of receipts that 

exist presently. 

Wastewater 

During 2021/22, expenditure on wastewater network reinforcement projects was less than infrastructure charges receipts. The net 

position at the end of 2021/22 was that the cumulative expenditure on wastewater network reinforcement is £0.3m less than  the 

infrastructure charge income received (2020/21: £1.3m more). The projected network reinforcement expenditure over the next five 

years has been reassessed and is not expected to be significant. We have reduced wastewater infrastructure charges to fund the 

next five year’s reinforcement expenditure whilst accounting for the £0.3m surplus of receipts that exist presently.

Services provided to the non-appointed business: 

Basis of recharge 

Treatment of imported sludge 

Treatment of tankered waste 
Other 

The average unit cost per tonne dry solid is calculated using operating 
costs only and excluding payroll.  This gives a unit rate which is more 
than the incremental cost but less than the income received therefore 
sharing the benefit of the activity. 

The recharge comprises recovery of operating costs of operator time and 
sampling and analysis and a charge for the use of appointed business 
assets, calculated using the Biological and Sludge elements of the trade 
effluent charge set out in the Company’s Wholesale Charges Scheme. 

  Other assets are specifically identified to the appropriate business.

FOR YEAR ENDED 31 MARCH 2022 

Information in relation to allocations and apportionments 

The appointed and non-appointed businesses operate separate accounting records including sales and purchase ledgers.  Revenue, 

operating costs, assets and liabilities are taken directly from these records. 

Revenue is separately recorded between wholesale water and wastewater and household and non-household retail services and no 

apportionment has been necessary.  Operating costs have been allocated between wholesale water and wastewater and household 

and non-household retail services in accordance with the guidance set out in RAG 4.10. 

Overhead costs incurred in the appointed business which relate to the non-appointed business have been allocated using an activity 

based approach to comply with RAG 5.07. 

Interest has been allocated between the appointed and non-appointed businesses on the basis of actual cash balances held by these 

businesses  during  the  year  at  market  rates.    Capital  costs  and  the  related  depreciation  charges  are  specifically  identifiable  to  the 

appropriate business and service. 

The  surrender  of  tax  losses  to  the  non-appointed  business  recognises  that  the  appointed  business  has  tax  losses  while  the  non-

appointed business has taxable profits which will be offset within the appointee’s tax return.

In addition, a special dividend of £159.0m was paid from the non-appointed business for the purpose of settling a legacy intercompany 

loan arrangement between the non-appointed business and NWGL. 

After the balance sheet date, the Board approved a final dividend of £55.4m for the year ended 31 March 2022. 

Dividend policy 

The  Board  has  a  policy  which  takes  into  account  the  principle  of  incentive  based  price  cap  regulation,  including  operating  and 

investment performance. When declaring dividends, the Directors consider the Company’s five-year plan and give due consideration 

to business performance, the prospects of the Company and the principal risks facing the business. 

Specifically, the Board determines the level of dividend declared by reference to: 

• 

• 

the Company’s ability to finance its functions;  

the Company’s cumulative financial performance and past outperformance; and  

•  maintaining the Company’s investment grade credit ratings.  

The Directors have also had regard to:  

• 

how the Company has satisfied its statutory and regulatory obligations, performed against the performance commitments 

in the final determination and the level of service provided to its customers; and  

• 

employees’ interests and, specifically, compliance with the pension deficit repair plan agreed with the Pension Trustee in 

respect of the NWPS, as submitted to the Pensions Regulator. 

Application of Policy 

Final dividend for the year ended 31 March 2021 

The Board approved the payment of a final dividend of £123.3m in respect of the year ended 31 March 2021.  Prior to this payment, no 

dividends had been paid in respect of the years ended 31 March 2020 or 31 March 2021, reflecting the impact of the PR19 FD and the 

uncertainty surrounding the CMA redetermination process and the Covid-19 pandemic. In approving the £123.3m dividend the Board 

took  account of  the Company’s financial position  at 31 March  2021,  cumulative  financial  performance over  the two  years  since  the 

previous dividend payment and the impact of the CMA redetermination on the five year plan which remained compatible with investment 

grade credit ratings.  The Board also took into account the principal risks facing the business, performance against statutory obligations 

and regulatory commitments, as reported in the 2020/21 APR, levels of customer service and C-MeX performance, positive ongoing 

employee engagement and payments made under the agreed schedule of contributions for the NWPS.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

During the year, the Board approved the payment of an interim dividend of £58.2m.  In reaching this decision, the Board took account 

of the underlying financial performance of the business, excluding the deferred tax restatement, and the Company’s updated five year 

plan which remained compatible with investment grade credit ratings.  The Board also took into account the principal risks facing the 

business,  strong  performance  against  the  majority  of  regulatory  ODI  commitments,  continued  high  levels  of  customer  service  and 

positive ongoing employee engagement. 

Final dividend for the year ended 31 March 2022 

After the balance sheet date, the Board approved the payment of a final dividend of £55.4m in respect of the year ended 31 March 2022.  

In  reaching  this  decision,  the  Board  took  account  of  the  underlying  financial  performance  of  the  business,  excluding  non-cash 

movements in  respect  of the  deferred  tax  restatement,  valuation  of derivatives  and  the impact  of high  inflation  on  index-linked  debt 

accretion, and the Company’s five year plan which remained compatible with investment grade credit ratings.  The Board also took into 

account the principal risks facing the business, continued high levels of customer service, performance against regulatory commitments, 

as reported elsewhere in this APR, and positive employee engagement. 

In considering performance for customers, the Board took account of the full range of performance commitments [reported on page X 

of the APR] both where the PC was achieved and where performance fell short of the target, noting that the overall performance was a 

net ODI reward.  Areas of positive performance included: 

• 

excellent customer service results on C-MeX (top two in the industry) and D-MeX, along with further extension of affordability 

support to customers and reduction in number of void properties; 

• 

continued industry-leading performance on interruptions to supply (excluding the exceptional storm Arwen event) and positive 

outcomes on burst mains and contact levels on appearance, taste and smell of water; 

awarding of 4* EPA, reflecting excellent overall environmental performance; and 

further progress on reducing greenhouse gas emissions towards our objective of being net zero by 2027. 

• 

• 

In respect of areas requiring improvement, the Board took account of the action plans being carried out to improve these areas, including: 

• 

the  substantial  investment  to  improve  water  quality  and  compliance  risk  index  score,  working  closely  with  the  DWI  on  a 

transformation plan; 

• 

• 

additional commitment both in terms of resources and investment to reduce leakage levels; and 

innovative  approaches to  reduce  the  causes  of sewer  flooding, such as  the  Bin The Wipe  campaign,  as  part  of a  broader 

flooding tactical plan. 

The Board also considered the significant interruptions to supply resulting from storm Arwen, noting that these were largely caused by 

power supply failures and recognising the tremendous effort put in by our teams to minimise disruption and return customers to supply 

as quickly as possible. 

The Board is fully aware of, and co-operating with, the ongoing investigations into FFT.  These investigations have not concluded and 

the Board will respond as appropriate in due course.

INDEPENDENT AUDITOR’S REPORT TO THE WATER SERVICES REGULATION 
AUTHORITY (THE WSRA) AND THE DIRECTORS OF NORTHUMBRIAN WATER LIMITED 

Opinion 

We have audited the sections of Northumbrian Water Limited’s Annual Performance Report for the year ended 31 March 2022 (“the 

Regulatory Accounting Statements”) which comprise:

flows (table 1F) and the related notes; and 

• 

the regulatory price review and other segmental reporting tables comprising the segmental income statement (table 2A),

notes. 

We have not audited lines 1F.4, 1F.9 to 1F.11, 1F.15 to 1F.20 and 1F.23 of the statement of financial flows (table 1F), the Outcome 

performance table (tables 3A to 3I) or the additional regulatory information in tables 4A to 4U, 5A to 5B, 6A to 6F, 7A to 7F, 8A to 

8D, 9A, 10A to 10E and 11A. 

In  our  opinion,  Northumbrian  Water  Limited’s  Regulatory  Accounting  Statements  have  been  prepared,  in  all  material  aspects,  in 

accordance with Condition F, the Regulatory Accounting Guidelines issued by the WSRA (RAG 1.09, RAG 2.09, RAG 3.13, RAG 

4.10  and  RAG  5.07)  and  the  accounting  policies  (including  the  Company’s  published  accounting  methodology  statement(s),  as 

defined in RAG 3.13, appendix 2), set out in section 4. 

Basis for opinion 

We conducted our audit in accordance with International Standards on Auditing (UK) (“ISAs (UK)”), including ISA (UK) 800,  and 

applicable law, except as stated in the section on Auditors’ responsibilities for the audit of the Regulatory Accounting Statements 

below,  and  having  regard  to  the  guidance  contained  in  ICAEW  Technical  Release  Tech  02/16  AAF  ‘Reporting  to  Regulators  on 

Regulatory Accounts’ issued by the Institute of Chartered Accountants in England & Wales. 

Our responsibilities under ISAs (UK) are further described in the Auditors’ responsibilities for the audit of the Regulatory Accounting 

Statements within the Annual Performance Report section of our report. We are independent of the Company in accordance with 

the ethical requirements that are relevant to our audit, including the Financial Reporting Council’s (FRC’s) Ethical Standard as applied 

to public interest entities, and we have fulfilled our 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.

FOR YEAR ENDED 31 MARCH 2022 

Emphasis of matter – special purpose basis of preparation 

We draw attention to the fact that the Regulatory Accounting Statements have been prepared in accordance with a special purpose 

framework,  Condition  F,  the  Regulatory  Accounting  Guidelines,  the  accounting  policies  (including  the  Company’s  published 

accounting methodology statement(s), as defined in RAG 3.13, appendix 2) set out in the statement of accounting policies and under 

the historical cost convention. The nature, form and content of the Regulatory Accounting Statements are determined by the WSRA. 

As a result, the Regulatory Accounting Statements may not be suitable for another purpose.  It is not appropriate for us to assess 

whether the nature of the information being reported upon is suitable or appropriate for the WSRA’s purposes. Accordingly we make 

no such assessment. In addition, we are not required to assess whether the methods of cost allocation set out in the accounting 

methodology statement are appropriate to the circumstances of the Company or whether they meet the requirements of the WSRA. 

The Regulatory Accounting Statements are separate from the  statutory financial statements of the Company and have not been 

prepared under the basis of international accounting standards in conformity with the requirements of the Companies Act 2006 (“UK 

IASs”). Financial information other than that prepared on the basis of UK IASs does not necessarily represent a true and fair view of 

the financial performance or financial position of a Company as shown in statutory financial statements prepared in accordance with 

the Companies Act 2006. 

The Regulatory Accounting Statements in section 4 have been drawn up in accordance with Regulatory Accounting Guidelines with 

a number of departures from IASs. A summary of the effect of these departures in the Company’s statutory financial statements is 

included in the tables within section 1. 

Our opinion is not modified in respect of this matter. 

Conclusions relating to going concern 

In auditing the Regulatory Accounting Statements, we have concluded that the directors’ use of the going concern basis of accounting 

in the preparation of the Regulatory Accounting Statements is appropriate. 

Our  evaluation  of  the  directors’  assessment  of  the  company’s ability  to  continue  to  adopt  the  going  concern  basis  of  accounting 

included: 

•  Assessing  financial  facilities  including  availability  and  access  at  the  balance  sheet  date,  the  nature  of  the  facilities, 

repayment and expiration terms and associated covenants; 

•  Assessing management’s ability to raise funds to finance the £350m bond falling due in February 2023; 

•  Evaluating  management’s  going  concern  assessment  and  the  linkage  to  the  business  model  and  medium-term  risks 

including effects of changes in water availability and usage and potential regulation; 

• 

challenging assumptions used in the forecasts, including the effects of AMP 7 from the Ofwat final determination and the 

subsequent CMA final decision;  

• 

• 

evaluating the amount of headroom in the forecasts focusing on cash and covenants associated with financing activities;  

performing  sensitivity  analysis  to  assess  how  the  headroom  within  the  forecasts  is  affected  by  variations  within  the 

assumptions; and  

• 

assessing the model used to prepare the forecasts, testing of clerical accuracy of those forecasts and assessing historical 

accuracy of forecasts prepared by management.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

Based  on  the  work  we  have  performed,  we  have  not  identified  any  material  uncertainties  relating  to  events  or  conditions  that, 

individually or collectively, may cast significant doubt on the company’s ability to continue as a going concern for a period of at least 

twelve months from when the financial statements are authorised for issue.  

Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of 

this report. 

Other information 

The  other  information  comprises  all  of  the  information  in  the  Annual  Performance  Report  other  than  the  Regulatory  Accounting 

Statements and our auditors’ report thereon. The directors are responsible for the other information. Our opinion on the Regulatory 

Accounting Statements does not cover the other information and we do not express any form of assurance conclusion thereon. 

In connection with our audit of the Regulatory Accounting Statements, our responsibility is to read the other information and, in doing 

so, consider whether the other information is materially inconsistent with the Regulatory Accounting Statements or our knowledge 

obtained in the audit, or otherwise appears to be materially misstated. If we identify an apparent material inconsistency or material 

misstatement,  we  are  required  to  perform  procedures  to  conclude  whether  there  is  a  material  misstatement  of  the  Regulatory 

Accounting 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 the other information, we are required to report that fact. 

We have nothing to report based on these responsibilities. 

Responsibilities of the Directors for the Annual Performance Report 

As  explained  more  fully  in  the  Statement  of  Directors’  Responsibilities  set  out  in  section  4,  the  directors  are  responsible  for  the 

preparation of the Annual Performance Report in accordance with Condition F, the Regulatory Accounting Guidelines issued by the 

WSRA and the Company’s accounting policies (including the Company’s published accounting methodology statement(s), as defined 

in RAG 3.13, appendix 2). 

The directors are also responsible for such internal control as they determine is necessary to enable the preparation of the Annual 

Performance Report that is free from material misstatement, whether due to fraud or error. 

In preparing the Annual Performance Report, the directors are responsible for assessing the 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 Company or to cease operations, or have no realistic alternative but to do so. 

Auditors’ responsibilities for the Audit of the Regulatory Accounting Statements within the Annual 
Performance Report 

Our objectives are to obtain reasonable assurance about whether the Regulatory Accounting Statements as a whole are free from 

material misstatement, whether due to fraud or error, and to issue an auditors’ 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 the Regulatory 

Accounting Statements.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

Irregularities,  including  fraud,  are  instances  of  non-compliance  with  laws  and  regulations.  We  design  procedures  in  line  with our 

responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our 

procedures are capable of detecting irregularities, including fraud, is detailed below. 

We considered the nature of the company’s industry and its control environment, and reviewed the company’s documentation of 

their policies and procedures relating to fraud and compliance with laws and regulations. We also enquired of management about 

their own identification and assessment of the risks of irregularities. 

We obtained an understanding of the legal and regulatory framework[s] that the company operates in, and identified the key laws 

and regulations that: 

•  Had a direct effect  on the determination of material amounts and disclosures in the Regulatory Accounting Statements. 

These included Regulatory Accounting Guidelines as issued by the WRSA, UK Companies Act, pensions legislation and 

tax legislation; and 

• 

do not have a direct effect on the Regulatory Accounting Statements but compliance with which may be fundamental to the 

company’s ability to operate or to avoid a material penalty. These included the company’s operating licence, regulatory 

solvency requirements and environmental regulations. 

In common with all audits under ISAs (UK), we are also required to perform specific procedures to respond to the risk of management 

override. In addressing the risk of fraud through management override of controls, we tested the appropriateness of journal entries 

and other adjustments; assessed whether the judgements made in making accounting estimates are indicative of a potential bias; 

and evaluated the business rationale of any significant transactions that are unusual or outside the normal course of business. 

In addition to the above, our procedures to respond to the risks identified included the following: 

• 

reviewing financial statement disclosures by testing to supporting documentation to assess compliance with provisions of 

relevant laws and regulations described as having a direct effect on the financial statements; 

• 

performing  analytical  procedures  to  identify  any  unusual  or  unexpected  relationships  that  may  indicate  risks  of  material 

misstatement due to fraud;  

• 

enquiring of management, the audit committee and external legal counsel concerning  actual and potential litigation and 

claims, and instances of non-compliance with laws and regulations; and  

• 

reading  minutes  of  meetings  of  those  charged  with  governance,  reviewing  internal  audit  reports,  and  reviewing 

correspondence with HMRC and WSRA. 

A further description of our responsibilities for the audit of the Regulatory Accounting Statements is located on the Financial Reporting 

Council’s website at www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report. 

Use of this report 

This report is made, on terms that have been agreed, solely to the Company and the WSRA in order to meet the requirements of 

Condition F of the Instrument of Appointment granted by the Secretary of State for the Environment to the Company as a water and 

sewage undertaker under the Water Industry Act 1991 (“Condition F”). Our audit work has been undertaken so that we might state 

to the Company and the WSRA those matters that we have agreed to state to them in our report, in order (a) to assist the Company 

to meet its obligation under Condition F to procure such a report and (b) to facilitate the carrying out by the WSRA of its regulatory

functions, 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 WSRA, for our audit work, for this report or for the opinions we have formed. 

Our  opinion  on  the  Regulatory  Accounting  Statements  is  separate  from  our  opinion  on  the  statutory  financial  statements  of  the 

Company for the year ended 31 March 2022 on which we reported on 15 July 2022, which are prepared for a different purpose. Our 

audit report in relation to the statutory financial statements of the Company (our “Statutory audit”) was made solely to the Company’s 

members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our Statutory audit work was undertaken 

so that we might state to the Company’s members those matters we are required to state to them in a statutory audit report and for 

no other purpose. In these circumstances, to the fullest extent permitted by law, we do not accept or assume responsibility for any 

other purpose or to any other person to whom our Statutory audit report is shown or into whose hands it may come save where 

expressly agreed by our prior consent in writing.

NORTHUMBRIAN WATER LIMITED ANNUAL PERFORMANCE REPORT  
FOR YEAR ENDED 31 MARCH 2022 

WHOLESALE TOTEX COMPARISON TO FD ALLOWANCE 

Totex (net of business rates, abstraction licence fees and grants and contributions) 

Actual  totex  in  2021/22  across  all  price  controls  was  £9.2m  lower  then  the  FD  allowance.  This  has  been  allocated  as  £39.8m 

underspend due to timing of expenditure, representing capex, and £30.6m overspend relating to ‘efficiency’, representing opex. 

The cumulative position for the first two years of the price control period is a total underspend of £25.2m, allocated on a similar basis 

as £42.0m underspend due to timing and £16.8m overspend relating to efficiency. 

The underspend due to timing is principally due to slower progress on enhancement projects. Enhancement costs and allowances 

are reported in tables 4L and 4M of our APR, which can be found on our website. However, in summary, for the first two years of the 

price control period: 

•  Water resources and water network+ enhancement expenditure is £53.1m lower than allowance; 

•  Wastewater network+ and bioresources enhancement expenditure is £21.8m lower than allowance. 

The  underspend  is  due  to  the  extended  lead  times  on  projects  exacerbated  by  the  Covid-19  pandemic.  Underlying  capital 

maintenance investment is higher then FD for the first two years. 

The overspend on operating costs is due primarily to unprecedented increase in energy costs during the year. 

Totex - business rates and abstraction licence fees 

Actual totex in 2021/22 was £3.1m lower than the FD allowance. This primarily relates to some rates rebates on wastewater treatment 

sites for both the 2021 and 2017 valuations which were settled during the year after extended discussions with the Valuation Office 

Agency. 

The  original  Ofwat  determination  set  consistent  cost  sharing  rates  for  abstraction  and  rates  variances.  However,  our  CMA 

redetermination amended teh sharing rates for different elements of these costs. In order for the sharing rate calculation to work 

correctly, a hybrid sharing rate has been used and reported in the row for ‘Customer cost sharing rate – business rates’ in line with 

Ofwat guidance. The individual rates are shown below

Shadow RCV 

Actual RCV at 31 March 2022, as published by Ofwat, was £4,547.9m. 

The projected ‘shadow’ RCV, adjusted for the customer share of cost variances was £4,554.1m, the small increase reflecting the 

customer share of overspends due to increased energy costs.

FOR YEAR ENDED 31 MARCH 2022 

Disallowable costs  

Costs classified as disallowable are:  

• 

pollution incidents (EA enforcement undertakings); 

•  Section 74 fines and fixed penalty notices; 

• 

• 

compensation claims; and 

the reversal of the prior year provision for innovation fund costs, in accordance with Ofwat guidance in IN 22/01 Expectations 

for monopoly company annual performance reporting 2021-22. 

Recharges in respect of ‘principal use’ of assets  

These relate to assets which are shared across more than one business unit, which mainly relate to IT systems and office buildings. 

The capital is allocated to Water Network+ as the ‘principal user’ and an appropriate proportion recharged to the other business 

units, including retail. The values are reported on table 2A.

and the environment. Our revenue allowance includes £2.5m per annum, which is recovered through customer charges, to contribute towards the Innovation Fund. 

To date there have been three rounds of competition, with four sets of projects awarded. However, only the projects from the ‘Innovation in Water Challenge’ were launched in 2021/22. NWL 

was the project lead on two projects, Organics Ammonia and UKWIR Centre of Excellence. as reported in the table above. 

Income received from the Innovation fund for these two projects was £475k and the NWL expenditure was £475k. This cost has been included in the totex tables 4D and 4E but reported as 

‘totex not subject to cost sharing’ in table 4C.  The company contribution of £25k is not in the appointed business expenditure. 

Innovation fund income received from customers was £2.526m (20/21 £2.512m).  £0.099m has been transferred to other companies for innovation projects that they are leading on. £0.028m 

has been allocated to the two projects above that NWL is leading on.  There was also a payment to Ofwat of £0.116m for the innovation partner administration charge.
