Payments for renewable energy heating systems

The UK Government introduced the world's first Renewable Heat Incentive to encourage the uptake of renewable heating technologies and help meet our target of 12% of heating coming from renewables by 2020
 

Non-Domestic Properties

 

The Renewable Heat Incentive started for non-domestic properties in 2011.   It provided an annual cash back payment for 20 years for renewable heating systems such as biomass, heat pumps and solar systems installed after 15 July 2009 (or after 4 December 2013 for non-domestic air source heat pumps and biomass CHP). The non-domestic RHI applied to business premises, public sector and community organisations together with district heating systems for multiple dwellings.  This scheme closed to new applicants on 31 March 2021.
 
 
 

Domestic Properties

 
For domestic properties, the RHI commenced in April 2014 and the level of tariff is higher than the commercial scheme but paid over a shorter 7 year period.  The amount of heat produced from the biomass boiler, heat pump or solar thermal scheme is normally deemed meaning that a heat meter is not required.
 
The tariffs are index linked annually.
 
From 1 April 2021 the domestic RHI tariffs are as follows:
  • Air source (air to water) heat pumps 10.92p/kWh (with a heat demand limit of 20,000kWh per annum)
  • Biomass boilers 7.01p/kWh (with a heat demand limit of 25,000kWh per annum)
  • Ground source heat pumps 21.29p/kWh (with a heat demand limit of 30,000kWh per annum)
  • Solar thermal 21.49p/kWh
 
Households need to meet certain minimum energy efficiency targets such as loft and cavity wall insulation.  Publicly funded grants received towards the installation, including RHPP are deducted from RHI payments. For biomass and heat pumps, the RHI is based on an estimated figure of heat (and hot water) demand from a domestic Energy Performance Certificate (EPC) up to the heat demand limits above. For heat pumps, this will be combined with an estimate of the heat pump's efficiency to determine the renewable proportion of the heat.  An electricity meter will be required with all heat pump installations to measure the electricity consumption of the heat pump.  For solar thermal systems, the payments will be based on the estimate of the system's performance completed as part of Geowarmth's installation of the solar system.
 
The domestic RHI applies to retrofit installations in single domestic dwellings and self build new homes.  It is limited to heating systems of less than a total of 70kW thermal output, although only MCS registered products up to 45kW output will qualify.  For larger domestic properties this means say a 60kW biomass boiler or heat pump will not qualify for the domestic RHI but two 30kW MCS certified products would qualify.
 
Second homes can also qualify under the domestic RHI but heat produced in second homes is usually metered rather than deemed.  Metering is also required in domestic dwellings if there is a fossil fuel boiler also installed.
 
A higher RHI payment can be obtained if Geowarmth install an optional metering and monitoring package.

The domestic RHI applies to installations since 15 July 2009 not just to installations completed since the launch of the scheme.  RHI applications must be made by 31 March 2022.  an Energy Performance Certificate is also required.
 
From 26 March 2016 all heat pumps must be ErP compliant and achieve a minimum seasonal performance factor (SPF) of 2.5 in order to qualify for the RHI.  The Energy Labelling Directive introduces a product label and a package label similar to that found on other domestic appliances.  All Geowarmth installations use high efficiency heat pumps which are ErP compliant and Geowarmth undertake the calculations to demonstrate the appropriate SPF has been achieved.

The domestic RHI scheme closes on 31 March 2022.
