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.
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 2018:
| Volume charge | £1.8382 | 45cm3 x £1.8382 = £82.72 |
| Fixed charge (for 90 days) | £9.00 | £36.50 yearly charge ÷ 365 days x 90 days = £9.00 |
| Sub total | £82.72 + £9.00 = £91.72 | |
Sewerage charges from 1st April 2018:
| Volume charge | £3.4150 | 45cm3 x £3.4150 x 95% = £145.99 |
| Fixed charge (for 90 days) | £9.88 | £40.08 yearly charge ÷ 365 days x 90 days = £9.88 |
| Sub total | £145.99 + £9.88 = £155.87 | |
Total:
Water - £91.72
+
Sewerage - £155.87
- Government contribution - £12.50 credit
= £235.09 for a family of 4 using 45 cubic metres of water in 90 days on a dual supply.
