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|
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.
