Water Self-Supply

Achieve complete control over water consumption and cost by dealing directly with wholesalers.

The opening of the UK’s water retail market in April 2017 gives non-household customers more choice over where and how they source their water, and most importantly the ability to supply themselves.

The Waterscan Water Self-Supply service is designed to provide you with complete control of water consumption and cost by dealing directly with wholesalers to achieve a greater saving, an enhanced service above that of national retailers, ensure accuracy in billing and give you the opportunity to influence the market. Waterscan will navigate the complexities of the market for you; support you in achieving and maintaining your licence and deliver comprehensive management of the administration of self-supplying water to your business.

Uniquely, with direct access to market data combined with our extensive water management experience, Waterscan is able to build a robust, tailored and evidence-based strategy. This transparency creates real efficiencies to drive down operational costs, achieve corporate social responsibility goals while creating further opportunities for investment in infrastructure and sustainability initiatives.

Water Self-Supply Service

This service is delivered through two stages, the first of which is to obtain your self-supply licence. Utilising our experience and approved systems, Waterscan will deliver all the licence application requirements on your behalf, working with you to understand and compile the necessary information to achieve success.

Once successful, Waterscan will represent you in market transactions and act as a managing agent to ensure licence compliance and deliver all the services a retailer would and more. Our existing Waterline© software system will be used to supply, receive and, most importantly, validate billing and settlement data; monitor and resolve emergencies and wholesaler issues; and inform the market dataset to reflect reality on the ground – all without taking a margin.

Ultimately, obtaining a self-supply licence puts you in control, enables Waterscan to deal directly with wholesalers for you, provides immediate benefit from market changes and delivers a combination of administrative and efficiency savings for you.

  • Compilation and submission of all relevant licence application forms on your behalf

  • Management of the application process with MOSL and Ofwat

  • Accurate data management on Central Market Operating System (CMOS)
