Don't have a water meter?

If you don't have a water meter you won't be able to do this test. Instead, you should check the areas of your home that are leakage hotspots. Click the button below for more.

Common indoor leaks

Step 1: Turn off all of your water using appliances

To perform a leak test, the first thing you'll need to do is turn off any water using appliances you might have. This includes appliances such as dishwashers and washing machines.

Step 2: Wait 30 minutes to allow any tanks or cisterns to fill up and then take a meter reading

Now you should wait 30 minutes to allow any tanks or cisterns to fill up then take a meter reading (including the red digits) and make a note of this as you'll need to check whether the reading goes up later. The video below explains how to read your meter.

Pipework responsibility

As your two meter readings were different it's likely you have a leak on your underground supply pipe. This is the water pipe leading from your property boundary to your internal pipework. 

If you live in a rented property it is your landlord’s responsibility to find and repair the leak. Please let them know you have a leak.

If you’re a business customer, speak to your water retailer for advice or click here to find out how you can apply for an allowance.

If you’re a household customer, have a water meter and you repair the leak within 6 weeks, you may be entitled to claim for the cost of the water lost during the time you had the leak. You can read more and check if you are eligible here.

  • Speak to your insurer - Check your home insurance policy to see if you’re covered for leaks on your water supply pipe
  • Check if you have a separate policy - Have you taken out a separate insurance policy which covers you for leak repairs on your water supply pipe?

    It’s always worth checking if you have one of these policies and whether it covers the cost of replacing any blocked paving or pressed concrete that needs removing to repair the leak.
  • We can help if your insurance policy doesn’t cover repairs - If your insurance policy doesn’t cover repairs to your water supply pipe then please call us on 0345 672 3723. Depending on where the leak is located, we may be able to help with the repair, subject to a number of conditions. Click here for further details about our ‘private leak repair scheme’.
