The domestic Renewable Heat Incentive

Submitted by Baerbel Epp on May 4, 2014
The domestic Renewable Heating Incentive (dRHI) for England, Wales and Scotland has been launched on 9 April 2014. For solar thermal, the dRHI will pay the end-user tariff at a rate of 0.192 Pound Sterling (GBP)/kWh for 7 years. The existing non-domestic RHI scheme continues at a new rate adjusted for inflation of 0.094 GBP/kWh for 20 years. The dRHI applies to biomass boilers & stoves, ground-source & air-source heat pumps heating and solar thermal DHW for single homes. The subsidy is for properties capable of getting a domestic Energy Performance Certificate (EPC) which confirms the property is a domestic dwelling. The recipient of the subsidy is the owner of the heating system. Northern Ireland does not yet have a domestic Renewable Heat Incentive.
This table was set up by Chris Laughton, Founder and Managing Director of The Solar Design Company in Great Britain.

  • Not for a new, unoccupied house unless self-built.

Requirements for installation

  • Domestic Energy Performance Certificate (EPC).
  • Green Deal Assessment (GDA) unless self-built home.
  • If GDA recommends loft and cavity wall insulation, this must be first fitted.
