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.

Emergency Plumber Search

Find a local WaterSafe approved plumber to help with your emergency.

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.

A Planned Approach to Finding a Good Plumber 

When undertaking any plumbing work, either scheduled or emergency, it’s important to take a planned approach in order to get a good plumber who delivers what you need; and to protect yourself from rogue traders and the consequences of sub-standard, potentially dangerous, work.

John Peerless, Principal Trading Standards Officer at Brighton and Hove City Council, and a former Chair of the Chartered Trading Standards institute, shares his tips for choosing and hiring the right plumber for your project:

We all want to have a worry-free experience when hiring a plumber to complete work on our homes and businesses, but many consumers simply don’t know enough about the process to feel comfortable. By following a few simple guidelines, you can be sure you’re hiring the right person for your job and protecting yourself from unscrupulous traders and businesses.

Firstly, you’ll want to identify the plumber you’d like to employ and verify their credentials. If you’ve used the WaterSafe postcode search, you’re guaranteed that the plumber you’ve found is accredited as a member in good standing of their trade association.

Why? WaterSafe have already done the vetting for you. The alternative is you’ll need to call the trade association yourself to validate the plumber’s claim to its membership.

That’s why I’m delighted to be part associated with WaterSafe, advising its Board of Directors on consumer protection issues. As a consumer, you can be reassured that WaterSafe approved plumbing businesses are fully qualified to carry out plumbing work in homes and business premises. They are specifically trained in Water Fittings Regulations, which enables them to ensure there should be no risk from poor installation or sub-standard materials that could cause contamination of the drinking water supply.

WaterSafe approved plumbing businesses must also adhere to the WaterSafe code of conduct and customer commitments – where they fail to meet these standards, a disciplinary process applies. Furthermore, a WaterSafe approved plumbing business which fails to uphold the standards will be subject to a range of penalties; in serious cases, this would result in its membership of WaterSafe being revoked.

You may also choose to get referrals or references. If possible, always ask to look at the work done, and be wary of any refusals or delays.

And one final piece of advice, always pick a plumber who will provide:

  • A physical address,
  • A contact telephone number,
  • An established time in business,
  • Their WaterSafe Registration, and
  • Their Gas Safe Registration (if they work on gas systems)

Even reputable tradesmen can make mistakes, so be sure that you have sufficient information to contact them if things go wrong so they can put it right.
