Non-domestic Renewable Heat Incentive (RHI)

The non-domestic Renewable Heat Incentive (RHI) helps businesses, public sector and non-profit organisations meet the cost of installing renewable heat technologies.

Types of heating

You can claim for:

  • biomass
  • heat pumps (ground source, water source and air source)
  • deep geothermal
  • solar thermal collectors
  • biomethane and biogas
  • combined heat and power (CHP) systems

Payments are made over 20 years and are based on the heat output of your system.

The money is paid through the Non-domestic Renewable Heat Incentive (RHI) scheme.


You can apply if your equipment was installed in England, Scotland or Wales on or after 15 July 2009.

Your equipment must meet certain requirements.
