Commercial Renewable Heat Incentive

The Renewable Heat Incentive can be received by owners of non-domestic buildings for 20 years based on the metered heat delivered from ground source heat pumps. Owners of ground source heat pumps systems (and other eligible renewable heat technologies) installed since 15 July 2009, can apply to Ofgem to be paid 9.56 pence/kWhour of renewable heat generated for the next 20 years.

The Renewable Heat Incentive can be received by owners of non-domestic buildings for 20 years based on the metered heat delivered from ground source heat pumps.

The RHI tariff table below shows the technologies eligible for Commercial RHI and the subsidy received for each technology. The RHI provides a major incentive for owners to invest in ground source heat pumps and solar thermal renewable heat technologies. The tariffs are based on pence/kWh of renewable heat delivered.

The rates are relevant to those considering investment in renewable energy systems. The grants vary with the technology and scale used for installations from the start of the month as follows:

¹No RHI is paid for air to water heat pumps if they are also capable of providing cooling.
Tariffs for ground source heat pumps over 100kW were degressed by 10% from April, and a further 20% from July 2020.

Additional specialist commercial RHI tariffs
