Our water supply charges
Each year we set our charges according to price limits that are determined by our regulator Ofwat every five years.
Here at Bristol Water we supply your fresh drinking water, so the water that you get from your taps in your home.
This can be a bit confusing when your bill arrives, as it will be a joint one with your sewerage service provider. They are responsible for taking water away from your house, like water from appliances, sinks and toilets, via their sewerage network. For the majority of our customers this will be Wessex Water.
How are charges set?
Bill charges for 2025-2026 have been published in line with Ofwat's final determination, and will take effect from 1 April 2025.
Every five years, water companies have to submit proposals to the industry regulator Ofwat, that set out plans for investment, spending and how they will raise money. Our charges are then set according to price limits that they agree.

For 2025/2026, the average water bill in the Bristol Water supply area will increase by 5% - from £222 to £234. An increase of £1 per month.
We know that price rises are always unwelcome, so rest assured if you’re struggling to pay, or think you might, we can give you a helping hand.
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. If you opt for a meter, we offer a money back guarantee scheme so you are entitled to a refund of your bill if your metered bills are higher than your 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.
