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 supplying water and taking away and treating used water.

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 2019:

Volume charge £1.8477 45 m3 x £1.8477 = £83.15
Fixed charge (for 90 days) £9.18 £37.34 yearly charge ÷ 366* days x 90 days = £9.18 
Sub total £83.15 + £9.18 = £92.33

 

Sewerage charges from 1st April 2019:

Volume charge £3.5832 45 m3 x £3.5832 x 95% = £153.18 
Fixed charge (for 90 days) £9.81 £39.88 yearly charge ÷ 366* days x 90 days = £9.81 
Sub total £153.18 + £9.81 = £162.99

 *2020 is a leap year

Total:

Water - £92.33
+
Sewerage - £162.99

-
Government contribution - £12.50 credit

= £242.82 for a family of 4 using 45 cubic metres of water in 90 days on a dual supply.
