How we calculate your bill

Information about how much we charge for 2021–22.

We review our charges every year – these are then approved by our Board.

  • The charges below are for the year 1 April 2021 to 31 March 2022
  • The majority of our customers live at a metered property
  • To help you calculate how much your bill may be, please see our water usage guide


Metered properties

Water meters record the amount of water used – we charge the following per cubic metre (one cubic metre = 1,000 litres).

Service Annual standing charge* Charge £ per cubic metre
Water supply £21.50 £1.487
Wastewater £23.81 £2.045
Surface water drainage £21.60**
Highway drainage £10.80

* For normal domestic meters
** In certain circumstances a surface water rebate is available.

 


Other charging methods

If you don't have a water meter you may be charged in one of the following ways:

  • By an assessment of the annual volume of water supplied to your home (assessed).
  • By the rateable value of your home at 31 March 1990 (unmetered).
  • If your home doesn't have a rateable value and you're not on an assessed charge, a fixed annual fee.

Has your bill gone up?

While everyone’s been at home more, we’ve all been using more water – so your bill may have gone up. Using less water could reduce your costs.
