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 2022:
| Volume charge | £1.9219 | 45 m3 x £1.9219 = £86.49 |
| Fixed charge (for 90 days) | £10.2255 | £41.27 yearly charge ÷ 365 days x 90 days = £10.23 |
| Sub total | £86.49 + £10.23 = £96.71 | |
Sewerage charges from 1st April 2022:
| Volume charge | £3.1317 | 95% x 45 m3 x £3.1317 = £133.88 |
| Fixed charge (for 90 days) | £13.4778 | £54.66 yearly charge ÷ 365 days x 90 days = £13.48 |
| Sub total | £133.88 + £13.48 = £147.36 | |
Total:
Water - £96.71
+
Sewerage - £147.36
- Government contribution - (£50 yearly credit ÷ 365 days x 90 days) - £12.50 credit
= £231.57 for a family of 4 using 45 cubic metres of water in 90 days on a dual supply.
