Assessed Household Charge
The Assessed Household Charge is only available for customers who have requested a water meter, but cannot have one installed on their property. This applies to properties where there is a shared supply pipe, such as flats.
This new charging system was agreed with our regulator, Ofwat in 2007. Properties are placed in one of three bands, based on the number of bedrooms, or a single occupier tariff.Our charges for 2010/2011 are highlighted in the table below.
| Band | No of bedrooms | Water charges | Wastewater charges | Annual total |
|---|---|---|---|---|
| 1 | Studio / One bedroom | £129 | £93 | £222 |
| 2 | Two bedrooms | £138 | £98 | £236 |
| 3 | Three or more bedrooms | £171 | £113 | £284 |
| Single occupier tariff | n/a | £100 | £75 | £175 |
Banding
If you were formally on the Average Household Charge and did not complete our survey to be placed on the Charge in 2007, your property will have been placed in band three by default.
Eligibility
If you have previously requested a water meter and were advised that one cannot be installed at your property, you may be eligible to be placed on our Assessed Household Charge tariff.
