Approved plumber / contractor

If you're looking for a plumber, we recommend you take a look at WaterSafe.


Please Note:

It is the individual plumber that is the 'Approved Plumber' NOT the plumbing company. To check which plumbers are approved within an organisation, click on the company link in your WaterSafe search results and look under the heading 'Recognised Plumbers'.

When we compiled the information on our approved plumbers search, the companies listed employed qualified named plumbers or underground installers, who are familiar with the requirements of the Water Regulations.

The WaterSafe Search page aim is to help you find the nearest qualified plumbing engineer local to you to help keep water supplies safe and healthy in homes and businesses.

Your contract will be with the approved plumber/underground installer and NOT Anglian Water so we cannot give assurance of their availability or guarantee their work.

Please make sure you receive a Certificate of Water Regulations Compliance from the plumber or underground installer, after they have completed the work.

We accept certificates of work from all seven existing approved contractor schemes. To gain discount on your connection please ensure that the plumber/underground installer is approved with APLUS and NOT one of the other schemes.

WaterSafe brings together thousands of qualified contractors employed by businesses from the seven existing approved contractor schemes across the UK.
