Welcome to Thames Water
We take care of water for 16 million people, enabling our customers, communities, and environment to thrive.
Save water this summer
It’s been a very dry spring and warmer weather is increasing demand for water. We’re investing £20 billion over the next 5 years to deliver our biggest ever upgrade. Our teams are fixing hundreds of leaks a week, improving our network across London and the Thames Valley.
Small changes at home can make a big difference, helping to reduce your bills and protect the environment.
