Approved Plumber Search

Find a local plumber you can trust using our free online directory search.

WaterSafe approved plumbers are certified by our national accreditation body, with specific training in the UK’s Water Fittings Regulations and Byelaws.

Hiring a WaterSafe approved plumber ensures that all plumbing work meets high standards and protects the quality of drinking water in your home and business, in England, Scotland, Wales, and Northern Ireland.

Water Support Services search

When planning a plumbing project, you may wish to hire specialised contractors, rather than a fully qualified WaterSafe Plumber.

These Water Support Services contractors include:

  • Groundworkers
  • Catering installers
  • Point of Use

These contractors are not approved WaterSafe plumbers, but they are recognised by the water company schemes APLUS, TAPS, WaterMark and WIAPS to carry out specific types of work in compliance with the Water Fittings Regulations and Byelaws. 


Groundworkers can work on the supply pipe (the underground pipe) supplying your property, up to the internal stop valve.

Catering installers

Catering Installers can install commercial kitchen equipment.

Point of Use installers

Point of Use Installers can install cold water chillers connected directly to the mains.

For further information or help, you should contact the relevant water company scheme.

For leaks, burst pipes, or other plumbing emergencies, WaterSafe’s emergency search will give you the contact details of a plumber who can help right away.

If you have no water, very low pressure or concerns about the quality of your water, you should contact your local water company straight away.

WaterSafe Calls for Customers to Only Trust Approved Plumbers

As part of a continued national awareness drive, WaterSafe, the UK’s national plumbing register, has launched a new nationwide media campaign designed to encourage consumers to check for credentials when choosing a plumber.

The high-profile campaign, fronted by renowned broadcast journalist and consumer expert Alice Beer, is called ‘Trust Approved Plumbers’ (TAP) and reveals where the nation places its trust, with an onus on what consumers place as priority when choosing a plumber.

The campaign launch (taking place on 25 September) follows new research carried out by WaterSafe which found that over half (54%) of UK homeowners would trust a tradesperson based on first appearances rather than professional credentials. More so, over two-thirds (67%) say fresh breath and attractive smell affect their opinion of a tradesperson, while for a third (30%) a trader’s togs affect how trustworthy they think they are.

Yet, in stark contrast, as little as 30% of Brits actually check a tradesmen’s professional credentials and are happy to judge them rather face value. This is despite the fact that it is estimated that rogue plumbers have cost the nation £2.6billion in recent years.

In a bid to raise awareness of the importance of checking a plumber’s credentials, WaterSafe has teamed up with broadcaster and consumer champion Alice, in a national media drive to urge homeowners to TAPTrust Approved Plumbers.

Julie Spinks, Director of WaterSafe, comments: “It’s a great shame that, while consumers are increasingly cautious in all others areas of their everyday life, there is still a lack of awareness about the importance of qualifications and how to check them, when it comes to choosing a tradesperson.

"The reality, however, of not using a properly qualified plumber is not only dangerous; it’s a false economy and could end up costing the homeowner a small fortune to repair, not to mention the safety hazards.

“Our message is simple – when choosing a plumber always use the WaterSafe website to make sure you get a qualified professional every time. In this way we, as a nation, can Trust Approved Plumbers. All homeowners need to do is go to the website, type in their postcode and it will provide them with several approved plumbing businesses in their geographical area….go to the WaterSafe website.”
