This research is structured around 5 evaluation questions covering both the scheme and levy, focusing on:

  • participant experience of the GGSS and GGL

The report draws on:

  • process evaluation reports for the GGSS and GGL
  • the first annual pulse survey of GGSS applicants and AD plants funded on the non-domestic Renewable Heat Incentive (ND RHI) scheme (undertaken between August and September 2023)
  • a review of literature on the UK biomethane market and its context
  • analysis of scheme and levy application and monitoring data
  • findings from 31 interviews

The department commissioned RSM UK Consulting LLP, supported by Winning Moves and Ricardo Energy, to undertake this research.
