Non-Domestic Renewable Heat Incentive

This scheme focuses on the non-domestic sector including industrial, commercial, public sector, not-for-profit organisations and communities with district heating schemes. Producers of biomethane are also included.

To claim the Non-Domestic RHI your installation must be accredited by Ofgem. It must have been installed on or after the 15 July 2009, and have not previously received public funding or grants.

Eligible technologies

  • Solid biomass meeting emissions limits
  • Solid biomass contained in municipal waste
  • Ground (and water) source heat pumps*
  • Air to water source heat pumps
  • Geothermal
  • Solar thermal (up to 200kW)*
  • Biogas combustion
  • Combined heat and power (CHP)*
  • Biomethane injection*

Ground (and water) source heat pumps, solid biomass and solar thermal plants of 45kW or less (and their installers) must also be MCS Accredited.

Eligible heat uses

  • Heating a space - rooms or enclosed spaces within a building
  • Heating water for direct use
  • Carrying out a process (within a building) excluding the generation of electricity
  • Carrying out a process (other than in a building) for cleaning or drying on a commercial basis

The heat generated must be in the form of water or steam, and satisfy a new or existing heat requirement. This must not be created artificially purely to claim the RHI.

Metering requirements

All installations require at least one heat or steam meter to correctly measure the eligible heat output (EHO).

Ofgem categorises each installation as having standard or multiple metering arrangements.

Installations with multiple metering arrangements require an Independent Report on Metering Arrangements (IRMA) to be completed.

Fuel requirements

For biomass and biogas installations, there are rules on the type and origin of the fuel.

The current Non-Domestic RHI tariff rates are published by Ofgem.
