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 2021:

Volume charge £1.9336 45 m3 x £1.9336 = £87.01
Fixed charge (for 90 days) £9.78 £36.98 yearly charge ÷ 365 days x 90 days = £9.78 
Sub total £87.01 + £9.78 = £96.79

 

Sewerage charges from 1st April 2021:

Volume charge £3.2938 45 m3 x £3.2938 x 95% = £140.81
Fixed charge (for 90 days) £13.60 £55.15 yearly charge ÷ 365 days x 90 days = £13.60 
Sub total £140.81 + £13.60 = £154.41

 

Total:

Water - £96.79
+
Sewerage - £154.41

-
Government contribution - £12.50 credit

= £238.70 for a family of 4 using 45 cubic metres of water in 90 days on a dual supply.
