What fittings are approved to use on the UK Water Supply System?

It is very important that any work you carry out on your water supply is done in the correct way, using the right fittings, to ensure that water remains safe and wholesome.

The Water Regulations Advisory Service (WRAS) can provide a free service to let you check which fittings meet the regulations. You can find the guide by clicking on the link below:

You should also be aware that you may need to tell us what you plan to do and you will have to have our permission. For more details please click the link Fittings Notification Regulations. This is a legal requirement and you risk a fine if you fail to tell us before you start work.
