Gate one submissions and final decisions

RAPID’s role in the gated process (working with the partner regulators and Natural Resources Wales) is to assess the progress made in development of each solution and to provide advice and recommendations to enable Ofwat to make decisions on continued funding for progression of the solutions.

The following decisions will be made at gate one:

  • whether solution and options within it should progress to gate two;
  • applying incentives and allowable costs;
  • whether alternative and/ or additional solutions should enter the process;
  • and what is required for gate two submissions.
