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.

What should be included in a plumbing contract?

Before you accept a quotation, you should form a proper contract. Verbal agreements are difficult to enforce and aren’t recommended.

A simple contract could be signed acceptance of the quote, while a more detailed contract could detail conditions and clauses that are binding on both parties – including what happens when things go wrong (which we cover in more detail here).

It is normal for start and finish times to be detailed in the plumbing contract. You may want to stipulate what time they will arrive and leave, and that they should come every day until the job is complete.

If the work is inside your home, check whether you need to remove any furniture, carpets, or curtains. Check what safeguards the plumber will make to protect your home, and confirm that the plumber carries public liability insurance in the event of any damage. Every WaterSafe approved business is required to hold public liability cover of at least £2 million and employers’ liability insurance where appropriate.

Be sure to check what items are excluded from the contract, as well. Pipework boxing or re-decorating as a consequence of the work will often be excluded from the price.

Spell out payment arrangements clearly in the contract. Check whether a deposit is required and when final payment becomes due. It is always preferable to make payments in a phased way up to completion.
