Great Britain: Performance of the two UK Renewable Heat Incentive Schemes

Submitted by Baerbel Epp on November 3, 2014
UK RHI statisticsThe UK has two Renewable Heat Incentives (RHI) that assist solar thermal. The non-domestic variant (non-dRHI) has operated since November 2011. The variant for households (dRHI) has operated since April 2014. Whereas the share of solar thermal applications within the non-DRHI is still low with 3 % (left chart), every fifth new domestic renewable heating system contains a solar water heater (right chart). For solar thermal, the non-dRHI currently pays 0.10 GBP/kWh for 20 years and the dRHI currently pays the end-user tariff at a rate of 0.192 Pound Sterling (GBP)/kWh for 7 years. Both rates will be annually adjusted for inflation through the payment period. The pie charts show the numbers of accreditations of non-dRHI and dRHI technologies.

Great Britain: Domestic Renewable Heat Incentives with Extensive Rules

Submitted by Baerbel Epp on April 23, 2014
The domestic Renewable Heating Incentive (dRHI) for England, Wales and Scotland has been launched on 9 April 2014. For solar thermal, the dRHI will pay the end-user tariff at a rate of 0.192 Pound Sterling (GBP)/kWh for 7 years. The existing non-domestic RHI scheme continues at a new rate adjusted for inflation of 0.094 GBP/kWh for 20 years. The dRHI applies to biomass boilers & stoves, ground-source & air-source heat pumps heating and solar thermal DHW for single homes. The subsidy is for properties capable of getting a domestic Energy Performance Certificate (EPC) which confirms the property is a domestic dwelling. The recipient of the subsidy is the owner of the heating system. So this can be the person owning and living in the home, a private landlord or a registered social landlord. In general it is not applicable to a new home unless this has been self-built. Other requirements are that the property should also have a Green Deal Assessment (GDA) and where the GDA recommends installing loft and cavity wall insulation, these must first be fitted before applying for the dRHI. New self-built house can be exempt from the GDA requirement, as these will be assumed to have adequate building insulation. There are initial costs to the user to first obtain the EPC and GDA. (Find more information in the database of incentive programmes.)
