Your plumbing fixtures must meet Water Supply (Water Fittings) Regulations 1999.
This applies to all plumbing fixtures, eg, pipes, taps, tanks, toilets and appliances, and also includes the service pipe from your house to the external stop tap.
Sometimes we can help with leaks on your service pipe. Find out more about our free leak repair service.
Making changes to your plumbing
There are certain water systems that you must tell us about before you begin installation work, eg, rainwater harvesting systems.
Find out more about how to notify us and see a list of installations we must be told about.
You are responsible for the repair and maintenance of the plumbing system, so it is worth checking your insurance policy to make sure you are covered adequately.
