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.

How Poor Plumbing is Causing Pollution

It may seem like a small mistake – one wrongly connected bit of plumbing. But that is all it takes to see waste from toilets, showers and washing machines flowing into our rivers and seas and polluting our environment. 

Andrew Broadbent, chair of the National Misconnections Group, explains why it’s important to ‘Connect Right’:

"Sewage and wastewater from toilets, baths, showers, dishwashers, washing machines and sinks should go straight into the sewers. From there it flows safely to wastewater treatment works where it is cleaned and recycled back into our rivers and seas. However, sometimes these appliances can be wrongly plumbed into surface water drains –separate pipes which should only collect rainwater (from roofs). Not only are these misconnections illegal, but they can result in chemicals, sanitary items and faecal matter flowing directly into our water environment and even harming our health and wildlife.

One misconnection in your home may seem quite minor on its own – just one washing machine or a sink. 

However, in some cases water companies have found as many as 12% of properties in one treatment area are misconnected.

It’s this build-up of pollution which can have a serious impact on the seas where we paddle and swim and the rivers where we fish and canoe and which are home for a wide variety of wildlife.

The recent enthusiasm for DIY and home improvements has probably added to the problem, as many people just don’t realise there are separate pipes for sewage and rainwater, and just connect to whichever is nearest! These plumbing mistakes can often happen during renovation projects, extensions and new builds.

So, who is responsible and how can we help prevent this pollution?

Ultimately the legal responsibility for getting plumbing right in the first place, and putting right misconnections, rests with the property owner. An easy way to making sure you’re not part of the problem is to employ a qualified, approved plumber listed on the WaterSafe register. This UK scheme is backed by the water industry and ensures plumbing businesses have the knowledge and qualifications to connect waste pipes properly.

The water industry is also working together on a ConnectRight campaign – with simple steps for households to take to check where their waste is flowing. So, if you do one thing today visit and help keep our beaches, seas and rivers clean for everyone to enjoy."
