Pipework responsibility
The owner or occupier of the premises is responsible for ensuring the design and materials used for the plumbing inside the building meet the national legal requirements.
This applies to all plumbing fixtures, including pipes, taps, tanks, toilets and appliances. It also includes the service pipe from your property to the external stop tap.
You are also responsible for the repair and maintenance of your plumbing system, so it is worth checking your insurance policy to make sure you are adequately covered.
