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.

Information for Customers

Hiring a WaterSafe approved plumber ensures that all plumbing work meets high standards and protects the quality of drinking water in homes and businesses.

WaterSafe approved plumbers have specific training in Water Fittings Regulations and Byelaws, which helps them protect you from poor installation or use of sub-standard plumbing products which could contaminate your drinking water.

Saves you money

We understand you need to manage your money carefully, but putting cost before plumbing credentials can have serious consequences.

Water safety in the home is very importance, and using unqualified plumbers who don’t know the law around fixtures and fittings could put your drinking water at risk.

Using an unqualified plumber is not only dangerous, it’s false economy – it could end up costing thousands of pounds and a lot of hassle to put mistakes right.

WaterSafe research shows Britons have spent £2.6 billion on fixing plumbing disasters, with nearly a quarter of people polled revealing they had fallen victim to a rogue plumber and a further 23 per cent knowing someone it had happened to. The average cost of a repair job came in at £426 – a cost we aim to help more customers avoid.

We recommend always getting three quotes from qualified plumbers, where possible, to ensure you get a reasonable price.

Saves you time

For most types of plumbing work, plumbers have a legal duty to notify the water supplier before they start work and this can lead to delays. Approved plumbers can carry out some work without the need to give advanced notification.

A ‘work completed’ certificate issued by a WaterSafe recognised plumber also provides a defence for property owners who are challenged by a water supplier enforcing the Water Fittings Regulations and Byelaws. A WaterSafe approved business will be required to put their work right if it does not meet the legal requirements.
