Who Supplies My Water? Find Your Water Supplier Today. (2022)

Who supplies my water? Who is my water supplier? These are common questions we wonder when we move into a new property. Selectra can help you get all the information you need about your water bill and water supplier, and answer your questions about water meters, water hardness, and more!

Water supply in the UK is broken up into over 20 companies that cover all UK residential areas. Unlike with other home bills, you don't get a choice of water supplier, therefore it's important to investigate who supplies your water.

How Does Water Work in The UK?

In the UK, there are generally two types of companies that handle the water supply. The first are the larger water and sewerage companies that handle both clean drinking water and wastewater treatment. The second are known as the water-only companies that provide just the clean drinking water.

Depending on your area, your clean drinking water and your sewerage might be handled by two separate companies. If this is the case, you will be billed by both of them, but usually you will only receive one bill from one company, who will bill you one behalf of the other.

For example, if you live in the South East:

  1. Your clean water will be provided by South East Water
  2. Your sewerage will be handled by Southern Water

Your bill will only be from South East Water, who will bill you on behalf of Southern Water, but this will be clear on your bill.

Who Supplies My Water?

Finding out who supplies my water in the local area is very simple. The water supplier operating in your local area will be responsible for supplying you with a reliable water supply that meets UK water quality standards. This includes ensuring that water is safe for human consumption and that water contaminants are below thresholds set by the Drinking Water Inspectorate.

In addition to water quality, water pressure is another crucial aspect of your home water supply. Too little water pressure results in boilers and appliances not functioning properly, as well as inconsistent water flow from taps and showerheads.

Water Bill Rates

Most homes in the UK have to pay for their water supply. Your water bill gets paid to the local water supplier who is in control of the water supply in your area. In some cases, water rates in your bill will also include a fee to cover sewerage and sanitation services that are often part and parcel of the work water suppliers do. Check out our detailed

How To Pay Your Water Bill guide to get the full picture of your water bill.

Water bills and water rates across the UK are regularly looked at by Ofwat, the industry regulator for residential water suppliers. This is supposed to ensure a balance between affordability and water suppliers being able to maintain infrastructures such as district piping and water quality equipment.

Don't expect water rates to be identical across every water bill in the UK. Water rates will vary depending on where you live in the UK, based on how hard it is to supply water to your area. Find out more about water in your town or city specifically.

You should find out who supplies your water to know exactly what your water bills will be like.

Check out our comprehensive guide on UK Water Rates to find out more.

What Is the Average UK Water Bill

The average UK water bill is how much we spend on our water and sewerage services in the UK. This depends on many factors.

As mentioned above, by far the biggest influence will be who is my water supplier. Since each UK region’s water is supplied by a different water company, the water rates will vary accordingly.

Other factors which influence your water bill will be how much you use and whether you are eligible for any support for your bills.

Who Supplies My Water Meter?

The water supplier operating in your community will be responsible for setting up and checking a water meter in your home. Not everyone has a water meter currently because there are different regional requirements as well as local water supply considerations. However, you can inquire about getting a water meter installed by contacting the relevant water supply company.

There are types of water meters that are provided by water companies. A standard water meter and a smart water meter. Find out more about both in our guides.
