How is my unmetered 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, account maintenance and managing enquiries.
Variable charge - This is based on the Rateable Value of your property. This is the figure that we use to calculate this charge on.
Here is an example of how we calculate unmetered bills:
 |
A yearly bill for a family living in a house where the property's Rateable Value was set at 250 on a dual supply (water and sewerage including surface water drainage) |
Water charges from 1st April 2023:
| Variable charge | £1.5764 | RV 250 x £1.5764 = £394.10 |
| Fixed charge (annual) | £173.42 | £173.42 per year |
| Sub total | £394.10 + £173.42 = £567.52 | |
Sewerage charges from 1st April 2023:
| Variable charge | £3.7432 | RV 250 x £3.7432 = £935.80 |
| Fixed charge (annual) | £168.93 | £168.93 per year |
| Sub total | £935.80 + £168.93 = £1,104.73 | |
Total
Water - £567.52
+
Sewerage - £1,104.73
- Government contribution - £50.00 credit
= £1,622.25 for a year on a dual supply where the Rateable Value of the property is 250.
As there is no meter at this property, this charge is not based on how much water is being used. There's more information here on switiching to a meter.
