If you think you might have a water leak, you can carry out a simple two-part test to confirm it and help identify where the leak is coming from.
This guide covers:
Test 1: Checking if there’s a leak
Test 2: Using the stopcock to locate the leak
Test 1: Is there a leak?
Step 1: Make sure no water is being used
Turn off all taps and make sure your washing machine and dishwasher are not running. There should be no water being used in the property.
If you’ve recently flushed a toilet or run a bath or shower, wait around 30 minutes before continuing — this allows any water already in the system to finish draining.
Step 2: Take a water meter reading
Go to your water meter. (If you’re not sure where it is, see our guide: How do I find my water meter and submit a reading?)
Take a clear photo of the meter showing the current reading, and send it to us for reference.
Step 3: Check the dial
Look closely at the small dial or indicator on the meter face.
If the dial is moving, even though no water is being used, this suggests there’s a leak somewhere in your property.
If it’s not moving, no leak is currently detected.
Test 2: The stopcock test
If you’ve confirmed a leak, this test helps you find out whether it’s inside the property or between the meter and the stopcock.
Step 1: Turn off your stopcock
Locate your stopcock and turn it clockwise to shut off the water.
(If you’re unsure where to find it, see our guide: Where is my stopcock?)
Step 2: Check the water is off
Turn on the cold tap in your kitchen sink. When the stopcock is closed, no water should flow — it may take a few seconds to stop completely.
Step 3: Check your water meter again
Go back to your meter and look at the dial.
If the dial is still moving even though the stopcock is closed and no water is coming from the tap, the leak is between the meter and the stopcock (outside or under the property).
If the dial is not moving, the leak is after the stopcock, somewhere inside the house (for example, a leaking pipe, toilet, or tap).
Step 4: Restore the water supply
Turn the kitchen tap off, then turn the stopcock anti-clockwise to open it again.
Step 5: Report what you’ve found
Let Bunch and your landlord or letting agent know the results of your test. They can help arrange any necessary repairs.
