Water Bill Higher Than Expected?

How to carry out a self-leak test

Is your bill higher than expected after a read has been taken? If you can’t think of a logical reason for the increased usage, chances are you have a leak.

They’re not always noticeable but they can waste a lot of water (and money) if they’re not fixed! It’s important for both the finances of your business and the environment to take the right steps…

1. Firstly, turn off your internal stop tap (usually located under the kitchen sink)

2. Find your meter, it should be outside your property. If you’ve found one, but aren't sure it's yours, you can check the meter serial number matches that on your invoices

3. If it’s safe, open the chamber and remove the polystyrene protection

4. Is the small meter dial moving? You may have a leak. Leaks within your property boundary are your responsibility, so you’ll need to call a plumber

If there’s no change to the water meter readings throughout this whole test then no water is escaping and there is no leak, you’re probably just using more water.

Wholesalers sometimes issue leakage allowances. In order to claim for one, you’ll need to send them the following information:


  • Who repaired the leak (e.g. plumber, yourself)

  • The date of the repair

  • A meter reading taken directly after the repair

  • A meter reading taken at least 14 days later
