Non-Domestic Easy Guide for applicants

Domestic RHI

The Domestic RHI covers homes in England, Scotland and Wales. It is intended for people who live in homes they own, private landlords, social landlords and people that build their own homes.

Within these categories, anyone who installed a renewable heating system from 15 July 2009 and meet the other eligibility criteria can apply. The system will need to be registered with Microgeneration Certification Scheme (MCS).

  •  Available to home-owners, private landlords and self-builders
  • NOT available for new builds or third party owners
  • Both the installer and the heat pump must be MCS certified
  • All equipment must be new at point of commissioning
  • System(s) must have been installed on or after 15th July 2009
  • Any system installed after the domestic RHI launch date must be applied for within 12 months of commissioning.
  • Before applying, home-owners and private landlords must have a Green Deal Assessment (this is not required for self builds due to current efficiency standards within building regulations). During the assessment you will be informed if you need to install loft and cavity wall insulation to qualify. This must be installed prior to making an application unless you have a valid reason why it is not possible. An updated EPC will be supplied with deeming calculations based on your building’s heat losses.
  • If you are a legacy applicant of a self build properrty, you will not require a Green Deal Assessment of your property, providing it was built to currrent building regulations. You will require an EPC.

Information required for application:

  • MCS certificate (supplied by installer/heat pump manufacturer)
  • EPC number
  • Green Deal Advice Report Number (not applicable for self builds)
  • Commissioning Certificate
  • Further information may be needed for second homes or properties with a back-up system.
  •  Made quarterly over a seven year period at 19.33p/kWh
  • Payments will be based on deeming calculations (from your EPC).
  • Any public grants used for funding will be deducted from the RHI payments over the seven year period.

The official domestic RHI calculator is now available online. This tool will enable you to calculate the potential income from a ground source heat pump installation.

Ofgem has published the following basic guides for the domestic RHI, which are listed below and available to download.
