Your bill

Understanding your water bill

Your bill is calculated in one of two ways:  

  • Metered charges are based on the amount of water you use. This is measured using a water meter. If your home is metered, the account type will show as metered on the top right hand side of your bill below your customer number.  The meter serial number can be found on page three of your bill along with your latest meter readings.
  • Unmetered charges are based on your home’s rateable value and not the amount of water you use. We are required by law to use the rateable values set by the Inland Revenue in 1990. Rateable values are different for each property. Ofwat has more information.

Your bill will be sent by Bristol Wessex Billing Services Ltd (BWBSL), a joint venture company owned by Wessex Water and Bristol Water. This joint arrangement relates to billing and payments only.  

If you receive your water from Bournemouth Water or Cholderton and District Water Company you'll receive two bills: one for your water supply and another from us for your sewerage services.
