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.

Why Should We Care About Leaky Loos?

Rosie Rand, Water Efficiency Project Manager at Thames Water, asks: "Why should we care about leaky loos?"

"So, leaky loos – why should you care??? Well a toilet that is constantly leaking clean water from the cistern into the pan can waste around 200 to 400 litres of water a day (2.5 – 5 bath tubs a day) and could add around £300 a year to your water bill if left unfixed. 

The worst of leaking toilets can waste up to 8,000 litres a day (100 bath tubs a day) and could cost you over £6,000 a year if not fixed!

Leaky loos have become a more significant problem recently due to a number of factors; the change in design of toilets from siphon to dual flush drop valves, along with more households replacing their water systems to mains-fed bathrooms.

1 in 20 households have a leaky loo, and this can be even more common in non-households, and yet they often go unnoticed. The leak could look minimal, and some people may even think this is a design feature to keep the toilet bowl fresh. Would you spot a toilet leaking? 

This video shows a toilet leaking around 600 litres a day and costing around £450 on an annual metered water bill – it doesn’t look like much water does it?

How to check if a loo is leaking:

If you can hear a flow of water when the toilet hasn’t been flushed or can see a slight but constant trickle at the back of the toilet pan, you may have a leaky loo.

Wait until 30 minutes after the last flush then wipe the back of the pan dry with toilet tissue.

  • Place a new, dry sheet of toilet tissue across the back of the pan. 
  • Leave it in place for up to three hours without using the toilet (it might be best to do this overnight).
  • If the paper is wet or torn in the morning, you know you have a leaky loo.

Once you know what a leaky loo looks like, it is surprising how many you spot while out and about. You may even find you have one at home too.

They normally are pretty straight forward for an approved plumber or keen DIY-er to fix, either by adjusting or replacing the bits inside a cistern with new parts for under £10. ( WaterSafe tip: Make sure the new parts are compatible with the WC and compliant with the water fittings regulations, for example, being approved by WRAS).

The water we use in our homes plays such an important part of our daily lives that it’s easy to turn on the tap without thinking about it. But to help us make sure there is enough water to go around, we need to use what we need and save where we can. So even if you are not on a water meter, it is still important to fix leaking toilets.

So next time you are using a loo, whether it is at home or when you are out or at work, check whether it is leaking and if it is, either get it fixed or report it to the right person!

Many people don’t think we have to worry about how much water we use in the UK, especially when it’s not hot or sunny outside. But the South East of the UK is classed as 'seriously water-stressed' by the Environment Agency. This means we have to do whatever we can to ensure water is used carefully, in order to protect the environment and ensure there is enough to go round for all our customers, whatever the weather.

We live in a country where it seems to rain a lot, yet London can receive less water than places like Sydney or Istanbul. There is also greater pressure on the amount of water we have available, with increasing population and changing weather patterns, making it more important for us to be ‘Water Smart’.  Water Saving Week is a great time to start thinking about the water you use.

So what else can people do to help? There are a lot of very simple and easy things that everyone can do to be Water Smart and reduce the amount of water they use without enjoying it less. For example, one minute less in the shower each day could save around 3,000 litres (around 40 baths) of water each year, which would save money on your water and energy bills too. Other things like turning off taps when you don’t need it to be running, or fixing drips and leaks is a great way to save water too.
