Our charges

Household charges

Ofwat control the amount we charge and it’s our responsibility to inform them exactly what we’re charging and how we plan to use the money. We review these charges every year to make sure our customers always get the best value service.

You can download a simple guide to our household charges below, or the full scheme if you want more detail. There are also some answers to frequently asked questions further down this page.


The District Valuer on behalf of the Inland Revenue originally assessed rateable values. They were based on the size of the property, the number of rooms inside the property, the amenities available and the overall location. No new rateable values have been set since March 1990 following the introduction of the Poll Tax.

Water companies are still legally entitled to use rateable value as the basis for charges, but we are not able to use council tax banding. New properties built since 1990 do not have a rateable value and are metered. If you have a property with rateable values you can choose to have a water meter installed. Call us on 0330 678 1485 to find out more.

Metered charges are made up of three elements – water supply, used water and surface water drainage.

Water supply and used water charges are based on the volume of water used. The amount used is calculated based on the difference between two meter readings.

These charges are levied for the removal and treatment of surface water or rainwater from your property.

Charges are based either on the rateable value of the property or based on property type, for example terraced, semi-detached or detached. If your charges are currently based on rateable value you can opt to be billed based on property type. If no surface water drains from your property or its surrounding area either directly or indirectly to the public sewer, you can claim exemption from this charge.

Please be aware the following charges differ depending on the rateable value of your property and where you live:

  • Sending cleaned and treated wastewater back into rivers and the sea
  • Converting solid material from sewage into gas for energy

Each year our bills increase for inflation, to reflect the increase in our costs. There are some other adjustments to reflect new investment and changes in cost which are agreed with our regulator, Ofwat, every five years.
