Thames Water is the UK’s biggest water and wastewater services provider, providing 2.7 billion litres of drinking water and safely removing 4.6 billion litres of wastewater every day. Our people provide essential services around the clock to c.16 million customers across London, the Thames Valley, and surrounding areas.
In 2025, we started the biggest upgrade to our network in 150 years, which will see a record-breaking investment of over £20 billion, fixing leaks, reducing pollution and protecting water quality, over the next five years. In 2024/25, we invested £2.2 billion, and we will continue to spend wisely on improving resilience, service, and efficiency, as well as provide more support for customers in vulnerable circumstances.
We also have additional responsibilities to society and the natural environment. What we do and how we do it delivers significant public value, which is why we have ambitious plans to self-generate more of our own power, reduce our carbon emissions and increase biodiversity across our sites.

Anglian Water supply water and water recycling services to more than six million domestic and business customers in the east of England and Hartlepool. Our services are at the heart of every single family and community in our region. We clean water to the highest standard, deliver it to millions of homes, and carefully manage it to ensure it never runs out.
We’re the largest water and water recycling company in England and Wales by geographic area. We’re also one of the driest regions in the country, with just 600 millimetres of rain each year, on average a third less than the rest of England. In fact some areas have a lower annual rainfall than Jerusalem. That’s why it’s vital that we look after the water that we’ve got.
