How to check for a leak at your property
Common sources of leaks in the home include toilets, dripping taps, showers, radiators and pipework.
Also look out for poorly plumbed appliances and overflows from a water tank or cistern in the loft. Check outside taps too.
Some leaks are hidden from view and easy to miss. If you're on a meter, a higher than normal bill may mean that there is a leak on one of your pipes or appliances.
Not sure where your meter is?
You can also sometimes find it in a wall-mounted box on the side of your home.
Now you can check your meter in a few simple steps:
If you're not on a meter, signs of a leak could be:
If you have a leak on your supply pipe outside your home, check with your water supplier as they may be able to help repair it. If you think you have a leak inside your property you'll need to contact a plumber. You can use our postcode search to find a WaterSafe recognised plumber near you.

Assuming the worst has happened, the first thing you should do is turn off all water at the stop tap (sometimes called stop cocks or stop valves).
The stop tap controls the water entering your home and is often sited under the kitchen sink, but it depends on where the service point enters the property. Sometimes you will have an additional stop valve in your loft or airing cupboard.
A good tip is to find these stop valves and label them before any plumbing emergencies occur. Try to gently turn them off and back on again. If it won’t budge, don’t force it - you’ll need to get a plumber to replace it.
The next thing you should do is open all cold water taps so the pipework and storage system drains quickly, this will help to reduce the damage. Do not turn on hot taps. Turn off the central heating system and, if it uses a solid fuel boiler, allow the fire to die out. Switch off any electric immersion heater, and then call a WaterSafe plumber.

Toilets are the cause of one of the most common leaks in the home, with around 1 in 10 homes and businesses having a leaky loo.
A toilet leaking clean water from the cistern to the pan can waste up to 400 litres of water a day (that’s five full bath tubs) and add around £300 a year to your water bill if left unfixed. See more useful facts and figures in this short film from Thames Water: https://play.buto.tv/bJ6n2
The sound of a constant trickle at the back of the toilet pan is an obvious sign that something’s not right. However, some leaks are silent and easy to miss.
To check if you have a leaky loo, contact your local water supplier who may be able to provide you with toilet leak detection strips free of charge.
To save water, money and energy don’t delay in getting your leaky loo fixed. If you need to replace a faulty toilet cistern, think about fitting a dual flush version that will save you several litres of water every time you flush.
