Under the UK Government’s domestic Renewable Heat Incentive (RHI) scheme, you could receive quarterly cash payments over seven years if you install or have already installed an eligible renewable heating technology.
The Renewable Heat Incentive (RHI) is a UK Government scheme set up to encourage uptake of renewable heat technologies amongst householders, communities and businesses through financial incentives. It is the first of its kind in the world and the UK Government expects the RHI to contribute towards the 2020 ambition of 12% of heating coming from renewable sources.
The domestic RHI was launched on 9th April 2014 and provides financial support to the owner of the renewable heating system for seven years. The scheme covers England, Wales and Scotland and is targeted at - but not limited to - off-gas households.
The UK Government's Department for Business, Energy & Industrial Strategy (BEIS) makes key policy decisions and energy regulator Ofgem E-Serve administers the scheme. Policy documents can be found on the UK Government website. The eligibility requirements and rules of the scheme are on Ofgem's website.
Ofgem have also published a document of case studies from the domestic RHI for information.
Further information about the domestic Renewable Heat Incentive can be found on this page. Please note that this information is not an exhaustive list of criteria for the scheme.
The UK government consulted on proposed changes to the domestic RHI scheme and these came into force in two phases.
Changes made included:
Please see the following guidance from Ofgem for more information about these changes:
This is not an exhaustive list of all of the changes to the scheme and further information can be found in the full RHI consultation response available on the Department of Business Energy and Industrial Strategy (DBEIS) website.
If you have any further questions at this stage then please find details in the full RHI consultation response
If you have questions about the policy decisions made in the consultation response you can contact BEIS at firstname.lastname@example.org or 020 7215 5000.
If you have questions about an existing DRHI application or a system already approved for DRHI payments please contact Ofgem eServe, the scheme administrators, at 0300 003 0744 between 9:00am-5:00pm Monday-Friday or at email@example.com.

RHI cash payments are made quarterly over seven years. The amount you receive will depend on a number of factors - including the technology you install, the latest tariffs available for each technology and - in some cases - metering.
You can estimate how much money you could earn through RHI using the Department for Business, Energy and Industrial Strategy's RHI payment calculator.
Please note there are some elements that could affect RHI payment.
Air to air heat pumps, all log stoves, pellet stoves without back boilers and hybrid PVT are not supported by RHI.
Water source heat pumps can potentially be eligible for the Domestic RHI – they are included in the definition of a ground source heat pump.
Certain cooker stoves and certain high temperature heat pumps may also be eligible.
All systems must also be listed as eligible on the Domestic Renewable Heat Incentive Product Eligibility List
All biomass fuel used by RHI participants must be sourced from a supplier on the Biomass Suppliers List (BSL) at the time the fuel was purchased. This is a list of suppliers of sustainable biomass fuel and it is advisable to check whether your fuel supplier is registered before entering into any long term supply contract.
Not all fuels from suppliers on the BSL are sustainable as they may supply more than one type of fuel. You should check with your supplier, or prospective supplier, which of their fuels are registered.
You must apply within one year of the commissioning date of your system.
You can apply for RHI via Ofgem's website. Providing you have all the relevant information to hand and your application does not require a manual review, you should receive an immediate decision. To check if your application will need manual review, visit Ofgem’s website.
If you are unable to apply online then you can contact Ofgem via their Domestic RHI Applicant Support Centre on 0300 003 0744 Monday to Friday from 09:00 to 17:00 or by emailing: DomesticRHI@ofgem.gov.uk.

Table last updated December 2018
The table above is taken from information published from Ofgem. You can see the tariffs on their Domestic RHI tariffs and payments pages.
These tariffs have been set by the UK Government at a level designed to compensate for the difference between costs of installing and operating renewable heating systems and fossil fuel systems, including non-financial costs such as disruption, on the basis of 20 years of heat produced. Fossil fuel costs used are those for off-gas households.
Most domestic systems payments will be based on an estimated heat output (’deeming’) and in some cases, meters are required to determine the technology’s heat output.
Changes to the domestic RHI mean that new heat pumps registering for the scheme must be metered
Further details can be found in Ofgem’s factsheets:
Metering and Monitoring Service Packages are an optional form of monitoring you could choose to provide peace of mind the renewable heating installation is working as expected.
The package works like a service contract between you and your installer, providing data and analysis to check the system is working efficiently.
A limited number of MMSPs are available for air source heat pumps, ground source heat pumps and biomass pellet boilers only. Applicants that successfully register for an MMSP will be paid additional support to help cover the cost of installing and operating the package.
You can register for MMSP when you apply to the domestic RHI scheme or afterwards. If you are successful you will receive MMSP payments alongside your quarterly RHI payments.
See Ofgem’s Essential Guide to Metering and Monitoring Service Packages (MMSP) for further details including information about eligibility, how to apply and expected payments.
