Standby water services

During weather-related water outages, or when leaks cause disruption to your water supply, we can provide standby water supplies to meet your needs. It is reassuring to know that you can access water wherever and whenever you need it. Whether it’s simply the supply of bottled water, or bulk supplies and tankered water which need to be delivered to address water supply in emergencies, Castle Water customers are assured of water supply continuity.


Consolidated billing

Consolidated billing provides a convenient way in which to receive and manage your multi-site costs in one simple invoice. This service is ideal for large, multi-meter and multi-site customers who wish to receive a single invoiced amount for all their water and wastewater charges, requiring just one single monthly payment. For multi-site customers we can also offer billing options that may be more preferential.

multi site

Direct Debit

Monthly Direct Debit is the easiest way to pay your bills and allows you to spread your water costs evenly over the year. Many customers choose to pay by monthly Direct Debit, just follow the quick and simple process here.


Meter reading

We take meter readings twice a year, or monthly if you are a large site or have a contract stipulating monthly reads. However, you can also provide additional meter reads yourself via our website (here) at any time.


Focus Academy Trust saved £7,500 on their annual water bill by switching to Castle Water as their sole water supplier, enabling them to reduce their water bills and re-direct funds towards front line resources.

Castle Water recovers over £13K in leak allowance for Verulam School

Award-winning customer service and fast leak repair

When a series of unexpected increased water bills indicated a leak, and call outs from private contractors were unsuccessful, Verulam School turned to Castle Water for support with leak concerns. Castle Water immediately organised a site visit to fix the unrepaired leak and completed a leak allowance application on the customers behalf. This resulted in Verulam School being granted a full leak allowance by their water network Wholesaler of over £13,600.

Kate Locke, Verulam School’s Business Manager, said: “I want to thank Castle Water for all your help in guiding us through this process and securing a leak allowance for the school. As you can imagine, the £13,629.20 allowance is a huge amount for a state school, and we are extremely grateful for all your support.”
