In a landmark moment for the water industry, the Water Services Regulation Authority (Ofwat), the independent regulator of water and sewerage in England and Wales, has given its approval for the merger of two long-standing water companies: Sutton & East Surrey Water (SESW) and Veolia Water UK. This paves the way for a new era for Sutton and East Surrey Water, which aims to create a stronger, more efficient water company that can better serve its customers in the South East of England.

The Proposed Merger

The proposed merger between SESW and Veolia Water UK was first announced in late 2019. The two companies have been working closely together since then, under the watchful eye of Ofwat, to ensure that the merger would benefit their customers and comply with all regulatory requirements.

The Benefits for Customers

According to SESW, the merger will bring several benefits to its customers. These include:

  • Improved water quality: The combined expertise and resources of the two companies will allow for better water quality monitoring and treatment.
  • Investment in infrastructure: The merger will enable significant investments in the water network, leading to improved reliability and reduced leakage.
  • Better customer service: The merger will lead to a more streamlined customer service experience, with a single point of contact for customers and improved digital services.
The Road Ahead

The merger is expected to be completed by the end of 2021, subject to final regulatory approval. During this time, both companies will continue to operate separately, with SESW focusing on delivering the best possible service to its customers in the meantime.


With Ofwat’s approval, SESW is one step closer to realizing its vision of a stronger, more efficient water company. The merger represents an exciting new chapter for the company and its customers, who can look forward to improved water quality, better customer service, and significant investments in infrastructure.

The Water Regulations Watchdog, commonly known as Ofwat (Office of Water Services), is an independent regulatory body established in 1991 under the Water Industry Act 1991. It is responsible for regulating water and sewerage companies in England and Wales, ensuring that they provide high-quality services at reasonable prices to their customers. Ofwat’s mission is to secure the best possible deal for consumers through effective regulation.

Regulatory Functions

Ofwat sets the rules that water and sewerage companies must follow, including price controls and environmental standards. It also oversees company performance through regular monitoring and reporting, enforcing penalties for non-compliance, and providing guidance to help companies improve their services.

Recent Application by SES Water

In March 2023, South East Water (SESW), one of the ten largest water and sewerage companies in England and Wales, submitted an application to Ofwat seeking approval on various business plans, including proposed price changes and investment initiatives. The application comes in the context of Ofwat’s current price review, which sets the prices that water companies can charge their customers for the next five years. The application includes detailed plans on how SESW intends to invest in infrastructure upgrades, improve customer service, and mitigate climate change risks.

Proposed Price Changes

SESW requested a price increase of around 6% per year for the next five years, which is slightly above the rate of inflation. The company argues that this increase is necessary to cover the costs of the investments required to maintain and improve its aging water infrastructure, as well as to meet the environmental standards set by Ofwat.

Investment Proposals

A significant portion of SESW’s application focuses on its investment plans, which include a £1.3 billion programme to upgrade and maintain its water network over the next five years. This includes projects such as replacing aging pipes to prevent leaks, improving water quality, and implementing smart technologies to enhance network efficiency and reduce customer disruptions.

Environmental Standards

Ofwat’s regulatory framework includes strict environmental standards, which companies must adhere to in order to secure approval for their business plans. SESW’s application includes details on how it intends to meet these standards, such as reducing leakage by a further 15%, achieving net-zero greenhouse gas emissions from its operations by 2030, and implementing measures to protect water resources and enhance biodiversity.


The application by South East Water to Ofwat marks an important step in the regulatory process for water and sewerage companies in England and Wales. The approval of SESW’s business plans, including its proposed price changes and investment initiatives, will have significant implications for the company’s customers, stakeholders, and the wider water sector. Ofwat’s decision on the application will set a precedent for future regulatory decisions and will reflect its commitment to securing the best possible deal for consumers while ensuring that water companies can invest in the necessary infrastructure upgrades to meet the challenges of the 21st century.
