Who is my water supplier?
In the UK, your water supplier is typically determined by your location. Most UK residents receive water from monopoly suppliers, meaning a single company provides water to each area. Once you move into a new area, you should register with the local water company to start paying for your water service.
Sometimes, water and sewerage services are divided. One company supplies your water, while another handles sewerage. Depending on your location, you may receive separate bills for water and sewerage services or a combined bill.
To identify your water and sewerage service providers, enter your postcode on the WaterUK website. This will show you the companies servicing your area and where to register to pay your water bill.
Can I change my water supplier?
Currently, domestic properties in the UK cannot change their water or sewerage service providers; only certain businesses can. Due to strict regulation, all UK water companies must meet high standards and cannot overcharge. This ensures a consistent water service across the UK, reducing the need for a competitive market like that of energy providers.

The benefits of the UK water supplier system
While you cannot choose your water supplier, the UK system ensures several benefits. All water suppliers in the UK must adhere to rigorous standards for water quality and service reliability. Prices are regulated by Ofwat, the government body overseeing water and sewerage services. This regulation keeps prices fair and prevents significant cost disparities between regions.
Suppliers are also required to reinvest in their infrastructure, which leads to ongoing improvements in service quality. Environmental protection is another critical aspect of the UK water supply system. Suppliers must follow stringent environmental standards to safeguard water sources and minimize their ecological footprint. Additionally, customer protection measures are in place, allowing Ofwat to investigate and address any issues with your water supply.
Comparing water suppliers when you move
Although Ofwat ensures consistent service, there are some factors to consider when moving:
Water hardness varies depending on the source of the water. There are 25 water suppliers in England, Scotland, and Wales, each sourcing water differently, which can affect its mineral content. Your preference may vary, and in hard water areas, you might want to use a water filter. Check Ofwat's website for water hardness comparisons.
Water rates, regulated by Ofwat, are proposed by suppliers every five years and reviewed to set fair pricing. This process makes it easy to compare costs before moving, though prices may vary slightly between regions.
If you're moving and looking to save on water bills, check if the new home has a water meter. Without a meter, reducing water usage won't lower your bill. Contact the local water supplier to see if a meter can be installed in your new home.
