Wholesale controls

pr14banner

When we next set prices in 2014 we will set separate price controls for retail and wholesale services. We will set two wholesale controls, one for wholesale water services and one for wholesale wastewater services.

The wholesale control covers the technical services that the companies provide ‒ such as treating water so it is fit to drink, and transporting it through a network of pipes to a customer’s property.

Our wholesale incentives are intended to benefit:

  • customers, by giving companies a sharper focus on delivering what their customers want and giving customers more say over the price they pay and the services they receive
  • the environment, by encouraging companies to use water more efficiently and incentivising them to choose environmentally sustainable and lower-carbon solutions
  • regulated companies (both incumbents and entrants) and investors, by allowing companies greater scope to innovate and for well-performing companies to outperform the controls we set
