In November 2017, Castle Water achieved recommended supplier status in the first aggregated further competition, enabling participating public sector customers in England to access the Crown Commercial Service, (CCS), framework for the provision of water and wastewater services. The framework allows public sector customers in England to switch to a single retail provider for their billing and account management services and secure their retail costs for 2-3 years.
Having switched to Castle Water through the framework, the partnership has benefited from competitive water rates, an experienced Commercial Relationship Manager, highly-rated customer support with experience to advise on a huge range of value-added services to help them get the most from their water services.
