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 2019:
| Volume charge | £1.8477 | 45 m3 x £1.8477 = £83.15 |
| Fixed charge (for 90 days) | £9.18 | £37.34 yearly charge ÷ 366* days x 90 days = £9.18 |
| Sub total | £83.15 + £9.18 = £92.33 | |
Sewerage charges from 1st April 2019:
| Volume charge | £3.5832 | 45 m3 x £3.5832 x 95% = £153.18 |
| Fixed charge (for 90 days) | £9.81 | £39.88 yearly charge ÷ 366* days x 90 days = £9.81 |
| Sub total | £153.18 + £9.81 = £162.99 | |
*2020 is a leap year
Total:
Water - £92.33
+
Sewerage - £162.99
- Government contribution - £12.50 credit
= £242.82 for a family of 4 using 45 cubic metres of water in 90 days on a dual supply.
