Report a leak

We have thousands of miles of water mains and water leaks can occur at any point. Your help is vital as we work round the clock to find and repair leaks on our network.

Each year our customers help us find and fix thousands of leaks and save millions of litres of water.

The South East is an area of ‘serious water stress’, so our leak detection team are dedicated to finding water leaks across our region, using sophisticated monitoring and acoustic systems.

However, the support of our four and a half million customers to report leaks can make a huge difference.

If you are aware of a leak please phone our 24-hour Leakline:

We will investigate and repair any leaks on our network as soon as possible.

Thank you for helping to preserve our precious resources.
