How do water rates work across the UK?
In England and Wales there are regional differences in domestic water rates. Your domestic water rate will depend on the availability of water in your region and the size of your region.
The majority of people are charged a yearly water rate which covers the domestic water supply and associated costs such as maintaining water quality. A minority of people have a water meter instead, which in some cases may prove a cheaper alternative.

- Meteredyour domestic water readings are taken from a water meter and you pay for the units of water you use.

What's the difference between water and sewage charges?
There are two parts to your water bill:
- Water charges are for the fresh water that comes out of your taps.
- Sewerage charges are for the water you use that goes back into the system as waste to be treated - assumed to be about 95%. This is also known as foul or grey water.
The sewage charge includes any water that runs from your property into public sewers.
How can I get a surface water drainage rebate?
Almost everybody pays for surface water drainage as part of the sewage element of their domestic water bill.
If you can prove that no water from your property drains into a public sewer - if you have a soakaway for example - you may be able to apply for a refund of your most recent charges. For further information, please contact your domestic water supplier.
How can I limit how much I spend on water?
