At Castle Water we’re committed to providing businesses with great-value water services.

When we launched Castle Water in 2014, we had a clear vision. To create an independent water retailer providing an excellent water service at the best possible price.

We're now the UK’s leading independent business water supplier, providing water and wastewater services to hundreds of thousands of businesses, charities and public bodies in England and Scotland. We're licensed by Ofwat and The Water Industry Commission for Scotland (WICS).

Servicing more than 350,000 customers, we're proud of the savings we've delivered with no ties to traditional network owners, which means we can fight for cost reductions while offering quality customer care.

Businesses use millions of gallons of water every day, but we focus on helping our customers use only what they need, while giving free advice about saving water. Our industry-leading partners are also on hand to offer additional water-efficiency services.

We’re clear on our corporate responsibility too, working with Save The Children to support its emergency fund, so children caught up in emergencies can access safe, clean drinking water when they need it most.

We love what we do and we’ll continue to shake up the water business with our customer-focused approach and fair prices.

Open water market

If you have a business in England or Scotland, you can take advantage of the open water market. With deregulation, businesses are no longer restricted to buying from local water boards or Network Owners. All businesses, regardless of size, can now choose their water and wastewater supplier – similar to the way you choose your energy or telecoms supplier. You can find out more about the open water market at: The open water market applies to business customers only.

Castle Water offers services to any type of business or organisation located anywhere in the UK. Unlike many water suppliers, we are not associated with any of the UK’s traditional Water Network Owners.
