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 | |
Total:
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.
