How are my Direct Debit payments calculated?

For customers who don't have a water meter, your annual charges are divided by the number of payments you choose to pay over.

For customers with a water meter, we estimate how much water you'll use in a year and divide the total into regular payments over 12 months. We calculate your estimated charges using your actual meter readings. The charges are calculated based on:

  • the amount of water recorded on the last 2 meter readings, plus standing charges
  • annual price increases
  • any balance outstanding (either because you used more water than we originally estimated or have missed a payment). The following year we'll adjust the amount you pay (up or down) based on how much water you're actually using

It takes at least 14 days to set up a Direct Debit, so your first payment will be taken on your chosen date after this period. You'll receive a schedule of payments in the post. If you register for My Account you can set up a Direct Debit online at a time that suits you.

The £5 annual discount will be taken off your first payment.
