Non-Domestic RHI

Government subsidies for renewable space and water heating

The Non-Domestic Renewable Heat Incentive Scheme (NDRHI) in Great Britain closed to new applicants at the end of midnight on 31 March 2021. The Department for Business Energy and Industrial Strategy (BEIS) has consulted on changes and published decisions in their government response documents which are available on the BEIS website.


The Renewable Heat Incentive (RHI) is a government scheme designed to increase the use of renewable energy to generate heat for UK properties.

If you install renewable energy heating such as Air Source or Ground Source Heat Pumps, Biomass Boilers or Solar Thermal systems, you may qualify for payments from the Renewable Heat Incentive.

For electricity-generating renewable technologies such as Solar PV and Wind Turbines, please refer to The Feed-in Tariff.

The Non-domestic RHI is open to industry, businesses and public sector organisations. The scheme is designed to incentivise businesses by generating a healthy return on an investment in renewable heating technology.
