About us

Who we are

We are a local water supplier, which for more than 150 years has supplied fresh, clean drinking water to our customers and communities. Throughout our history, the people at SES Water have remained committed to delivering this core purpose – it’s what we’ve done and it’s what we will always do.

What we do

We supply around 160 million litres of clean water every day to more than 750,000 people in parts of Surrey, Kent, West Sussex and South London.

Our purpose

We believe it’s not just our duty
to supply water, but to use it as
a force for local good. That’s why
we are doing all we can to support
the communities we serve,
while protecting and enhancing
our local environment.

It’s been another busy year for the Company and, as many will be aware, we’ve also had an additional focus on managing the strategic review initiated by our previous shareholders, Sumitomo Corporation and Osaka Gas.

This strategic review concluded in the purchase of the Company by Pennon Group plc at the start of 2024 and approval of the merger by the CMA on 14 June 2024. We’re excited about the opportunities our new shareholder will bring to the business and our customers, and on behalf of the Board and the Company I would like to thank Sumitomo Corporation and Osaka Gas for the strong support over their many years of ownership of our Company.

The Board and I take our obligations for good corporate governance extremely seriously and these standards are kept under continuous review. As ever, the strength and depth of the Company means it is well placed to progress in what has become an increasingly challenging sector to operate in.

Both our Environmental Scrutiny Panel (ESP) and our Customer Scrutiny Panel (CSP) continue to consistently scrutinise and challenge the work we do. Both groups play a key role in monitoring our performance and challenge the progress of our improvement plans. We welcome their constructive feedback, and I would like to thank the members on both panels for their continued support.

Overall, I’m proud that we’ve continued to deliver industry leading water quality – the foundation and core responsibility of any water company.

We’ve also advanced innovation and have started seeing the benefits from the deployment of our smart network technology, helping us to achieve our target for leakage reduction. In fact, our smart network has enabled us to reduce our leakage by nearly 15% since 2020.

Just as important has been assisting our customers wherever we can through our financial support schemes and priority services register, providing the extra care to those customers that need it. In moments where customers have been affected by burst pipes, I’ve witnessed great compassion and dedication among our teams to go the extra mile and be there for our customers.

I’m also proud of the operational teams who manage our network 24/7 and who have kept the supplies running throughout adverse weather conditions across the year, ranging from especially dry periods in the summer to a very wet winter. With the ever-changing climate a constant reminder, what I have seen this year has just re-confirmed my confidence in our teams being prepared for any situation.

In addition, our water resources put us in good stead for the summer months ahead, following an especially wet winter, and we are proud to have not implemented a hosepipe ban within our supply area for over a decade.

And while managing all the above I’ve been consistently impressed by our ability as a team to develop and submit an exciting and ambitious PR24 submission, alongside our visionary long-term delivery strategy. Through the deployment of cutting-edge technology we are planning to balance the needs of a growing population and focus on the environment, while delivering industry leading water quality for decades to come. It’s all about the best quality water all day, every day, today, tomorrow and into the future.

With customers in mind I’m not only pleased with what we have done to deliver high-quality water every day, but also the part the team has played in many community outreach programmes, from our education programme to community support, assisting those who require that extra little bit of help.

We’ve also held more community events and developed more partnerships with local charities and groups than ever before, and this has helped us forge a closer bond with our customers. It has been positive to hear some of the feedback received from these events, which also provides us with valuable customer insight, although we acknowledge there is more to be done here to raise levels of customer satisfaction.

With our smaller size, and being focused on providing drinking water only, we can be agile, fast, risk-taking and innovative. This has allowed us to develop a close relationship with our communities and push the boundaries of technology for the greater good of our customers, water network and the industry as a whole.

The Board has also maintained a close working relationship with our regulator Ofwat and other key stakeholders, such as Consumer Council for Water (CCW), keeping them regularly apprised of important business matters.

It’s pleasing to see our recent efforts on debt and equity raising have improved the liquidity and financial resilience of the Company. However there continues to be significant adverse pressure on overall financial results from escalating operational costs due to inflation and meeting performance commitments.

Cost of living and macro-economic conditions have also hit cash collections and therefore have increased our bad debt provision in the year. It’s also worth noting no dividends were paid to our shareholders this year.

Meanwhile we’ve continued to make great strides in enhancing and protecting the biodiversity across all our operational sites, and I was delighted to see us achieve a third Biodiversity Benchmark Award from The Wildlife Trusts – this time for our water treatment works at Bough Beech Reservoir. We remain the only UK water company to hold this prestigious award, which is a fantastic achievement.

In summary, our performance has been good in a very demanding year, and I would like to thank the SES Water team for all they have done and the dedication to the future plans which they exhibit every day. Working in an industry which is rightly scrutinised from all angles requires the workforce to have a great deal of resilience and determination and it is a testament to this team that we continue to be a high-performing Company. Great job team.

As I reflect on the past year, it’s clear the public and political pressure on water companies is intense and there is significant focus on how they adapt to better serve customers and the environment in the future.

With that backdrop in mind, I’m very proud of how we’ve performed, achieving c70% of our performance commitments and leading the industry in a number of key areas – in particular our water quality, our leakage reduction and continuing to build the resilience in our network.

STRATEGIC REVIEW OUTCOME

As we release our Annual Report, we do so off the back of completing a strategic review of the business which concluded with acquisition of the Company by Pennon Group plc at the start of 2024, which the CMA has now approved.

It’s clear Pennon has been impressed by our business, our performance and our people. It has ambitious plans for growth and wants us to be part of that vision for the future as we embrace the challenges the sector faces. It shares our aspirations for our customers and, over time, will create exciting opportunities for our people.

Understandably, strategic reviews can create uncertainty and I am personally thankful for the support of our Board throughout the process. At the heart of this new era for the Company is ensuring we continue to be industry-leading for our customers and the environment. It is clear our strong performance has demonstrated our value, as we proudly move into the Pennon Group.

SUPPORTING OUR CUSTOMERS

Continued levels of high inflation and the cost of living crisis continue to impact our day-to-day operations. This has posed a significant challenge for our customers and I’m all too aware of the impact necessary but tough decisions can have, such as the increase in our annual tariff for household and non-household customers.

Customers rightly expect us to deliver high standards of service and value for money. It was therefore extremely disappointing to experience a rare, severe, mains burst where a small number of customer homes in Gatton Park, Redhill, were flooded.

Our focus was unstinting and fully on looking after those customers impacted and our teams mobilised with commendable efficiency, working around the clock to address the situation head-on, offering steadfast support to our customers.

Our efforts not only mitigated the impact of the situation but also embodied the spirit of solidarity and empathy that defines our Company.

More broadly we continue to provide support for those customers who require extra care, with 2,800 more customers now receiving financial help from our water support programme and a 30% increase in customers now on our Priority Services Register.

INDUSTRY LEADING PERFORMANCE

I was delighted to see that for 2023 our water quality risk index score is likely to place us as the top-ranking company for water quality in the Drinking Water Inspectorate’s 2024 report.

We’ve maintained our industry leading leakage performance, reducing leakage by nearly 15% since 2020, by using our smart network technology and staying at or below the maximum allowed level of leakage every year since the target was first set back

in 1999. I was pleased to see BBC South East feature our smart network technology for the first time. It was great to see the dedication of our teams and how they go the extra mile for our customers in action.

We’ve also laid 6.2 kilometres of new water mains in the past year and progressed a number of key mains replacement schemes across our supply area. As a result, we’re on track to meet our target for the number of mains repairs in the remaining year of the Asset Management Plan (AMP).

We also completed an important mains replacement scheme on the busy A22 Godstone Road in Purley, directly benefitting 27,000 properties in the Purley area and vastly improving the resilience of the local water supply network. This means we’re nearing completion of a 15-year resilience programme we’ve been progressing since 2010. By 2025, every property across our region will be supplied by more than one treatment works. This was an outstanding achievement amidst an incredibly busy year.

In addition, achieving a third Biodiversity Benchmark Award from The Wildlife Trusts for enhancing and protecting the biodiversity at our Bough Beech site proved to be another standout success for us this year – alongside retaining the awards we already hold at our Elmer and Fetcham Springs sites. I’m proud we remain the only water company to currently hold the award. Furthermore, our vehicle fleet now comprises 43% electric and hybrid vehicles, with the aim to reach 100% by 2030.

We also continue to deliver our commitment to achieve zero serious pollutions, with no category 1 or 2 pollution incidents caused in over 16 years.

THE LOOK AHEAD

We submitted our most ambitious plan ever to Ofwat with our PR24 submission totalling an expenditure of £413m. It proposes an increase of £13m per year to reduce leakage, install smart meters for all customers, improve the resilience of our water treatment works and supply network to climate change, and protect and improve our local environment. We’ve considered a range of future scenarios for climate change, population growth, technology advancement and abstraction reduction, identifying the investment we need to make over the next five years and beyond. We’re pleased to have spoken to so many customers across our communities about these plans and hear their feedback.

CONNECTING WITH OUR COMMUNITIES

We’ve established stronger connections and fostered deeper relationships with key stakeholders. This heightened engagement with our local MPs and local councillors

is important for us as it reinforces our dedication to transparency, collaboration, and proactive involvement in local communities.

Building new partnerships and strengthening our relationships with local organisations has been another key priority for us this year and we have continued to play an active role in the communities we serve. The past year has seen us award more than £20,000 to three local charities and support 27 local community events, which has led to more than 1,100 conversations with customers. We’ve also welcomed more than 3,200 students and teachers to our ‘Flow Zone’ education centre at Bough Beech reservoir, helping them to learn more about water and how they can use less and help protect the environment. I’m proud that we’ve opened up our visits to schools outside our supply area ensuring we educate our future customers, too.

As we look ahead, we do so with confidence that we remain industry leading in a number of key performance areas. Our ambitious PR24 plan will further help us deliver on our promises for our customers, as we embark on our new journey with the Pennon Group.
