When it comes to electricity and gas, switching your business supplier is as easy as switching your domestic supplier.

However, when it comes to business water suppliers, unlike your domestic water, you have the choice of which water supplier to use.

Water deregulation in England came into force in 2017, enabling business customers to use the service provider of their choice. This gave UK businesses the opportunity to shop around for the best deal, allowing them to negotiate cost savings as well as taking advantage of other services on offer such as flexible payment options, consolidated billing and tailored water management services. The competitive nature of the deregulated supply also encouraged retailers to improve their customer service and provide more services to benefit their customers, such as online service portals and water efficiency advice.

Since then, businesses of all sizes have saved millions of pounds by switching their business water supplier and negotiating a better deal.

How does it work?

When you switch business water supplier, you won’t notice any changes to your water supply. The basic infrastructure of getting water to your taps is the same - the regional sewerage and water companies will act as ‘wholesalers’, providing your water and wastewater needs. The difference is that, as business water suppliers, we act as the ‘retailer’, buying water and sewerage services from the wholesalers and packaging and pricing our own services. As the UK’s leading independent business water supplier, Castle Water has greater buying power enabling us to negotiate better deals and pass on savings to you and all our customers.
