If you don’t have a water meter, click here to find out how we calculate what you owe. If you're on a water meter you’re billed based on the amount of water used at your property. Here’s a list of reasons your bill might be higher than you expected.

• Your previous bill may have been based on an estimated reading which was too low. When this happens, your following bill will include any charges not covered by the amount on your previous bill.
• Your latest bill may cover a longer period of time than your previous bill. The longer the bill period, the more water you will use
• The number of people living at the property may have increased; for example, a friend or relative could have moved in, you may have had a baby, or you may have had visitors over to stay.
• You may have dripping taps; a dripping tap can waste 18 litres a day and could add an extra £20 a year to your bill!
• You may have carried out renovation or decorating work, using more water than usual.
• The time of year can affect your bill; we normally expect your summer bill to be higher than your winter one. This is because we tend to use more water in the summer.
• You may have a leak on an appliance like a washing machine or boiler, or a leak on your pipes (although these are rare!) If you think your pipes may be leaking, click here to find out what to do.
