Welcome to Thames Water
We take care of water for 16 million people, enabling our customers, communities, and environment to thrive.
Protect our most precious resource: water
As temperatures rise, it's more important than ever to use water wisely. We're asking all our customers to be mindful of how they use water at home.
Small changes - like fixing a leaky loo or using a water butt - can help you save water, energy, and money.
