Our dedicated team will provide your organisation with:

  • Full service support for correct consents and licenses and the application process
  • Wholesaler negotiation for bespoke consent limits
  • Guidance to meet regulatory obligations
  • Support and data reporting to help reach your sustainability and environmental targets

Consolidated billing

Consolidated billing provides a convenient way to receive and manage your multi-site costs in one simple invoice. This service is ideal for multi-site customers who wish to receive a single invoiced amount for all their water and wastewater charges, requiring just one single monthly payment. Depending on the size of your school or campus, consolidated billing could be the right option for you.

Standby water services

During water outages, we can provide standby water supplies to meet your needs. Whether it’s simply the supply of bottled water, or bulk supplies and tankered water, contact us and we can work with you to establish a continuity plan that meets your needs.

Effective water management at independent schools

With so much water needed for the day-to-day running of your school, a water efficiency strategy can bring huge benefits. The majority of independent schools need facilities for boarders, which means the provision of washing and toilet facilities that are used 24/7, as well as laundry facilities. From breakfast to supper, boarders need feeding, so the kitchens will be preparing daily meals for everyone.

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.

“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.” - Kate Locke, Business Manager at Verulam School
