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.

Variable 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:

Variable charge £1.9184 45cm3 x £1.9184 = £86.33
Fixed charge (for 90 days) £9.24 £37.48 yearly charge ÷ 365 days x 90 days = £9.24 
Sub total £86.33 + £9.24 = £95.57

 

Sewerage charges:

Variable charge £3.5695 45cm3 x £3.5695 x 95% = £152.60 
Fixed charge (for 90 days) £9.78 £39.68 yearly charge ÷ 365 days x 90 days = £9.78 
Sub total £152.60 + £9.78 = £162.38

 

Total:

Water - £95.57
+
Sewerage - £162.38

-
Government contribution - £12.50 credit

= £245.45 for a family of 4 using 45 cubic metres of water in 90 days on a dual supply.
