Our water supply charges
Each year we set our charges according to price limits that are determined by our regulator Ofwat every five years.
Each year we set our charges according to price limits that are determined by our regulator Ofwat every five years. Your supply is either unmetered, metered, or assessed and this affects the way we charge for your water supply:
Unmetered
We use the rateable value of your property and calculate the cost for the year in advance.
Metered
We read your meter twice a year and you pay for the water you use.
All domestic customers can ask for a meter to be installed free of charge. For those who opt for a meter, we offer a money back guarantee on your meter; customers are entitled to a refund of their bills if their metered bills are higher than their unmetered bills.

Assessed
Where you have requested a meter, but it is not possible for us to install one and you do not wish to remain on unmetered charges, you may be placed on an assessed charge and billed per number of bedrooms.
For 2024/25, the average water bill in the Bristol Water supply area will be £222 a year, an increase of £9 (4.2%) from last year. This works out as 61p per day for your water, which is treated, regularly monitored, and then transported straight to your tap.
The increase in your average bill is influenced by several key factors:
- CPIH inflation of 4.2%;
- the outcome of the CMA PR19 Final Determination, which increased K factors and bills for 2024/25;
- mitigated by performance, regulatory adjustments, and customer movements.
