Non-Domestic Renewable Heat Incentive (RHI)

The Renewable Heat Incentive (RHI) is the world’s first long-term financial support programme for renewable heat. RHI is a UK government scheme that pays participants who generate and use renewable energy to heat their buildings. The government expects the RHI to make a significant contribution towards meeting targets for the reduction of greenhouse gas emissions and the effects of climate change.

Non-domestic RHI has been open to commercial, industrial, public sector, not for profit and heat networks since November 2011. The scheme is designed to bridge the gap between the cost of fossil fuel heat installations and renewable heat alternatives through financial support for owners.

Domestic RHI was launched 9 April 2014 and open to homeowners, private landlords, social landlords and self-builders.

Non-Domestic Renewable Heat Incentive

The non-domestic Renewable Heat Incentive (RHI) helps meet the cost of installing renewable heat technologies for businesses, public sector and non-profit organisations. These include, for example, businesses, hospitals, schools, and district heating schemes such as in the case of where one boiler serves multiple homes.

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