Renewable Heat Incentive

The non-domestic Renewable Heat Incentive (RHI) was first implemented in 2011 to reward businesses who generate heat using eligible renewable technologies.

The following renewable heat technologies receive support under the RHI:

  • Biogas Combustion
  • Solid Biomass (including CHP)
  • Ground/Water Source Heat Pumps
  • Air Source Heat Pumps
  • Deep Geothermal
  • Biomethane Injection
  • Solar Thermal

Preliminary accreditation (preliminary registration for biomethane plants) is available to help developers plan their projects.

As of October 2015, RHI claimants using biomass feedstocks in their installation need to demonstrate compliance with Sustainability Criteria. Further details can be found here.

Below are some of the services Greenspan offer to assist RHI claimants:

  • Guidance on legislation
  • Support on meeting requirements and claiming under the RHI
  • Greenhouse gas emissions calculations for current and future biogas feedstocks
  • Management of applications to Ofgem for the RHI
  • Periodic data submission to Ofgem for operational RHI installations
  • Heat Loss Assessments
  • Schematics
