Renewable Heat Incentive (RHI)

The Renewable Heat Incentive (RHI) is a government incentive, which pays the owner of eligible renewable installations over time for the heat that is produced. The RHI is run by Ofgem, who manage both the application process and payments.

The scheme covers both domestic and non-domestic properties and is designed to help meet the cost of installing renewable heat technologies.

The types of heating covered by the scheme are:

  • Ground source heat pumps
  • Air source heat pumps
  • Water source heat pumps
  • Biomass
  • Solar thermal hot water
  • Biomethane and biogas

As part of your RHI application for a heat pump system you will require an SPF calculation, which conforms to EN14825. You can visit to get help with your SPF calculations.
