Non-Domestic RHI

Renewable Heat Incentive for Commercial Ground Source Heat Pumps

The Non-Domestic Renewable Heat Incentive Scheme (NDRHI) in Great Britain closed to new applicants on 31 March 2021.


The RHI is a Government scheme designed to reward businesses that use carbon-neutral fuel sources including Ground Source Heat Pumps for heating and hot water. Payments are calculated based on the amount of heat you use. Typically the cost of installing a Ground Source Heat Pump is paid off by the incentive in less than five years with returns averaging 20% p.a. for 20 years.

Does your business qualify for the Renewable Heat Incentive?

For a commercial property to qualify for the Non-Domestic Renewable Heat Incentive, your business must be registered at the address of the property and you must be paying business rates. Domestic schemes can also qualify for the Non-Domestic RHI if the heat pump is used to heat two or more domestic properties from one heat source. For domestic heat pumps, heating just one property, please refer to the Domestic Renewable Heat Incentive.
