What Is Water Self Supply?

Since April 2017 both the English and Scottish water markets have been open to competition enabling any business to choose their water retailer. For all large and multi-site water users, the water regulators have approved water self-supply as one of the most cost effective and transparent ways to purchase water.

The Benefits of Self-Supply

  • Buy water at the wholesale price
  • Pay NO retail margin
  • Full visibility of your consumption and cost data at a per meter level
  • Direct relationship with wholesalers enabling quick resolution of any issues

These benefits will only increase over time as wholesale costs are expected to decrease in the next few years.

Our Fully Managed Water Self-Supply Service

We provide a fully managed service that will enable a hassle free switch to self supply and provide on an ongoing basis the following services:

  • Single point of contact for all sites across the country
  • Accurate and consolidated billing and detailed consumption data for water, wastewater and trade effluent
  • Management of all problems and emergencies with any wholesaler across the country
  • Automatic Meter Reading (AMR)
  • Option to work with any water efficiency or leak detection company including with one of our strategic partners who provide these services

To maximise water efficiency gains we have partnered with trusted national water efficiency and engineering companies allowing our clients to pick the best provider for their specific industry and scenario. This ensures a choice of the best water reduction service at the best price rather than a single choice of provider.
