Grant
Renewable Heat Incentive (RHI)
The Renewable Heat Incentive (RHI) is the new Government-backed scheme superseding the grants system from the Low Carbon Buildings Programme (LCBP), providing excellent financial pay-back for a wide range of microgeneration heat production technologies.
Available for domestic, “non-for-profit” and commercial users, the Renewable Heat Incentive (RHI) gives owners of heat-generating technologies, including biomass, air and ground source heat pumps and solar thermal, attractive financial returns on their investment. Due to be introduced in April 2011, it is designed to reduce CO2 emissions across the UK and reduce our dependance on traditional fossil fuels, including oil and gas. Please refer to the table below for a list of the proposed Tariffs.
