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 2020:
| Volume charge | £1.9101 | 45 m3 x £1.9101 = £85.95 |
| Fixed charge (for 90 days) | £9.42 | £38.20 yearly charge ÷ 365 days x 90 days = £9.42 |
| Sub total | £85.95 + £9.42 = £95.37 | |
Sewerage charges from 1st April 2020:
| Volume charge | £3.3364 | 45 m3 x £3.3364 x 95% = £142.63 |
| Fixed charge (for 90 days) | £13.28 | £53.85 yearly charge ÷ 365 days x 90 days = £13.28 |
| Sub total | £142.63 + £13.28 = £155.91 | |
Total:
Water - £95.37
+
Sewerage - £155.91
- Government contribution - £12.50 credit
= £238.78 for a family of 4 using 45 cubic metres of water in 90 days on a dual supply.
