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.

WaterSafe Warning to Use Approved Plumbers After ‘Pink Water’ Costs Firm Thousands

Homeowners and businesses are being urged to use the national WaterSafe directory to find approved plumbers after a fruit farm was fined thousands for contaminating the public water supply.

Poor plumbing landed Haygrove Ltd, based in Herefordshire, in court after the farm’s faulty pipework turned local people’s water pink.

Customers are now being advised to use the free online register, WaterSafe, to find qualified plumbers who are trained in the Water Fittings Regulations and Byelaws.

WaterSafe is a service which brings together approved plumbing businesses and is backed by all UK water companies.

Haygrove Ltd had to pay more than £6,000 in fines and court costs, and more than £5,000 in compensation to Severn Trent Water – a total of more than £11,000 – after pleading guilty to offences under the Water Industry Act last year.

Severn Trent Water investigated the fruit farm after receiving reports of pink water from local residents. Strawberry fertiliser was found to be leaking into the mains water supply due to badly connected plumbing.

Water companies are advising customers not to put cost-cutting ahead of quality when it comes to plumbing work and instead strongly recommend using WaterSafe approved installers.

They are also reminding homes and businesses that it’s a legal requirement for customers who want to alter private plumbing connected to the network to notify their water company beforehand, so they can check the work is safe.

Ian Mitchell, Water Fittings Regulations Manager at Severn Trent Water and WaterSafe Board member said: 

“WaterSafe is a free, invaluable service, to help keep the water supply healthy after it reaches customers’ homes and businesses.

“It is a fast and simple way for anyone in the UK to know their plumber is qualified and the work is being carried out within the law and not putting people’s health at risk.

“We would urge everyone to use the WaterSafe service, not only because it helps to protect the quality of the water supply, but also because ultimately it could save them a court appearance and a large fine.”
