Switch to Castle Water for award winning business water services for companies and organisations of all sizes.
More 5-star reviews than all other water retailers combined.
Castle Water is the UK’s leading independent business water retailer, supplying hundreds of thousands of businesses, charities and public bodies throughout England and Scotland.
Our association with the Crown Commercial Service continues to grow and we remain focused on upholding the highest standards that our brand embraces, providing all our customers with a market leading service and, importantly, value for money to the public sector in the UK.
When you switch to Castle Water, your organisation will have the full support of our Crown Commercial Service team and a dedicated Portfolio Manager.
With fair pricing, a smooth transfer process, straightforward billing options, instant online access to your account and support to improve sustainability and cut costs, you’ll be glad you made the switch.
While our full team is always available to provide support, your Castle Water account will be allocated to a dedicated Portfolio Manager, so you’ll have the ease of one point-of-contact who will help to ensure your organisation gets the most out of our services.
Our job is to let you get on with yours. One simple bill for all your water and wastewater, paid securely by Direct Debit means you can spend more time where you’re needed most. Log in to MyAccount to see everything all in one place, anywhere, anytime.
Whether your organisation is a single site or multi-site customer, you can choose the invoicing option that’s right for your current processes. From one invoice with one payment for multiple accounts, to separate invoices, to EDI billing.
We’ll work with your organisation to help cut costs, build resilience, and reduce its carbon footprint.
Your Castle Water Portfolio Manager can provide support to identify opportunities to improve water efficiency and help manage water efficiency projects.
It’s easy to submit regular meter readings on MyAccount so your bills stay up-to-date and you only pay for the water you use.
Plus, for every meter reading you submit that we use to calculate your bill, we donate £1 to Save the Children’s Emergency Fund.
Trade effluent requirements can be complex. Castle Water’s dedicated, expert trade effluent team has the experience and technology required to understand it like no one else – and we make the process simple.
Everything you need to stay in control of your account, all in one place.
