Leaks on water mains can be slow and gradual or erupt very quickly with visible water flooding.
If the water leak is in your garden then there's probably a fault on your supply pipe – which you're responsible for.
Where possible, immediately turn the water off at your stop tap. If this isn't possible, we'll arrange for someone to attend as a priority.
We offer up to one hour’s free detection work to help locate the leak on your private supply pipe.
For more information read our Code of Practice on water leaks, which details our responsibilities for the ownership of supply pipes and eligibility for repair.
Contact our customer call centre on 0330 303 0368 (calls charged at local rate) and we will arrange for someone to visit your home.
If there is a water leak outside the boundary of your property, for example on the road or footpath, we will repair it as quickly as possible and restore water supplies.
