This quarterly release provides a summary of the deployment of renewable heat technologies under the Non-Domestic Renewable Heat Incentive (RHI) and Renewable Heat Premium Payments (RHPP) householder voucher schemes. Note that from January 2015 RHPP figures were no longer included in this release, and that from March 2016 quarterly data is now included within the Renewable Heat Incentive (RHI) and Renewable Heat Premium Payments (RHPP) monthly deployment data release.

Since its inception in April 2014, the number of applications for the Renewable Heat Incentive (RHI) in Great Britain made by households increased to over 114,000. The most common technology type introduced were air source heat pumps. The RHI scheme is a payment scheme meant to support renewable heat generation.

This statistic shows the amount of heat paid for under the Renewable Heat Incentive (RHI) since the scheme was launched in April 2014 in the United Kingdom (UK). A total of 3,285,847 megawatt hours was paid for under the domestic component of the scheme between 9 April, 2014 and 31 December 2018.

Great Britain has begun a transformation to a low carbon heat system, launching the non-domestic Renewable Heat Incentive (RHI) in 2011 and further implementing RHI in the domestic sector in 2014. A large proportion of applicants are located in regions with large rural areas such as Scotland and the South West. Both regions had applications and accreditations exceeding 11 thousand units. This trend is likely to be attributable to the fact that many rural areas are not on the gas grid, and will be replacing solid fuel or oil burning systems with systems powered by renewable sources of energy, such as air source heat pumps, ground source heat pumps, biomass and solar thermal systems.

This statistic shows the fuel types being replaced with renewable systems under the Renewable Heat Incentive (RHI) since the domestic program was formally launched in April 2014 in the United Kingdom (UK). Oil was the most common heating system to be displaced, with a total of 19,275.

Air source heat pumps, also known as reverse-cycle air conditioners, is a system which transfers heat from inside to the outside of a building or vice versa. Electricity was the most common fuel to be replaced by air source heat pumps. As of December 2019, 30 percent of the fuel types displaced by this renewable technology were originally run on electricity.

Great Britain has begun a transformation to a low carbon heat system, launching the non-domestic Renewable Heat Incentive (RHI) in 2011 and further implementing RHI in the domestic sector in 2014. Scotland has the largest number of RHI applications and accreditations. Under the RHI, fossil fuels have been replaced by air source heat pumps, ground source heat pumps, biomass and solar thermal systems.
