As the home-owner, you are responsible for repairing and maintaining any pipes connecting your home to the water board's network. If you're a tenant, you'll need to check with your landlord to find out which of you is responsible.
This includes pipes running inside and outside the home, within the property boundary. The external stop tap usually marks the edge of the boundary.
If you rent your home, your landlord or letting agent may be responsible for these pipes. Check your tenancy agreement or speak to your letting agent or landlord to confirm this.
If you're moving in to a new home, and the property is over 20 years old, we recommend that you find out about the condition of the pipework.
If supply pipes are neglected it can affect the water supply and damaged pipes can go unnoticed, storing up problems for the future.
Leaks and bursts on private property are your responsibility.
