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.
Our commitment to personalised service means that we’re not just another water supplier – we’re your dedicated partner in success. With Castle Water, you can expect prompt and attentive customer support that’s designed to meet your unique business needs. Say goodbye to the hassle of managing multiple providers and complicated billing systems – our streamlined approach makes it easy to consolidate all your water services into one simple, transparent bill.
We offer an individual, responsive service, whether you’re a small company just looking for a water provider or you’re a large industrial customer with several sites and complex wastewater needs.
There are many UK-based companies which offer water treatment services. However, many of these businesses do not have the background in water efficiency and management which naturally lends itself to providing an all-round better service.
Servicing more than 250,000 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.
