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 2018:

Volume charge £1.8382 45cm3 x £1.8382 = £82.72
Fixed charge (for 90 days) £9.00 £36.50 yearly charge ÷ 365 days x 90 days = £9.00 
Sub total £82.72 + £9.00 = £91.72

 

Sewerage charges from 1st April 2018:

Volume charge £3.4150 45cm3 x £3.4150 x 95% = £145.99 
Fixed charge (for 90 days) £9.88 £40.08 yearly charge ÷ 365 days x 90 days = £9.88 
Sub total £145.99 + £9.88 = £155.87

 

Total:

Water - £91.72
+
Sewerage - £155.87

-
Government contribution - £12.50 credit

= £235.09 for a family of 4 using 45 cubic metres of water in 90 days on a dual supply.
