How is my metered bill calculated?

Your bill is made up of a fixed charge and a variable charge.

Fixed charge - This covers our costs for operational activites, for example: managing the infrastructure for supplying water and taking away and treating waste water, reading and maintaining your meter, account maintenance and managing enquiries.

Volume charge - This is based on the amount of water you use in cubic metres. 5% allowance is given for the water that doesn’t go back into our sewers for drinking, cooking and gardening.

Here is an example breakdown of how we calculate metered bills:

  A family of 4 use 45 cubic metres of water in 90 days on a dual supply (water and sewerage including surface water drainage)

 

Water charges from 1st April 2022:

Volume charge £1.9219 45 m3 x £1.9219 = £86.49
Fixed charge (for 90 days) £10.2255 £41.27 yearly charge ÷ 365 days x 90 days = £10.23 
Sub total £86.49 + £10.23 = £96.71

 

Sewerage charges from 1st April 2022:

Volume charge £3.1317 95% x 45 m3 x £3.1317 = £133.88
Fixed charge (for 90 days) £13.4778 £54.66 yearly charge ÷ 365 days x 90 days = £13.48
Sub total £133.88 + £13.48 = £147.36

 

Total:

Water - £96.71
+
Sewerage - £147.36

-
Government contribution - (£50 yearly credit ÷ 365 days x 90 days) - £12.50 credit

= £231.57 for a family of 4 using 45 cubic metres of water in 90 days on a dual supply.
