Homeowners, self-builders, landlords and local authorities can get a grant towards the costs of an air source heat pump as part of the Government Renewable Heat Incentive scheme.

As part of the drive to install one million heat pumps (including air source heat pumps) , across the UK homes before 2030, the Government is offering some great funding incentives.

The Renewable Heat Incentive Scheme (RHI), set up by the a UK government, administered by Ofgem  to promote usage of renewable heat technologies. There are two schemes, the domestic and non-domestic scheme. The RHI covers specific renewable technologies including Air Source Heat Pumps, and provides home owners and businesses a generous financial incentive for adopting these environmentally friendly renewable technology. The RHI is payable quarterly for seven years to homeowners, self-builders, private landlords and local authorities. Once you have installed an air source heat pump we will provide with all the information that you need to for you to register with Ofgem for the RHI.

The Current RHI scheme is only confirmed in until March 2022 and it is not currently known what the position will be for installations after this date. So now is the ideal time to install with the current generous cash incentive.

Homes that are not currently connected to the national gas grid, which is estimated at in excess of more than 3.6 million in England and Wales are ideal for this initiative. These properties, currently using, oil, coal and electric heating are very expensive to heat and have higher carbon emissions. This means they have the highest potential to help the Government meet the reduced carbon emissions target. These properties also have the largest potential for financial savings by changing to renewable technology.

The Domestic RHI is ideal for retrofit properties as well as new self-build properties. For an average 3 bed family home, in the UK needing 15,000 KWH per annum, the total RHI payment received could be in excess of £9,500. Often clients receive in the region of £10.5k under under the RHI and this covers nearly all of the costs of the air source heat pump installation. BEIS provides a handy RHI calculator to estimate what you may receive under the RHI

The RHI incentive is not available for new build properties, but with the upcoming current planned legislation the way we heat, build and power homes will have to change. From 2025 the Government intends to ban carbon based central heating systems (including gas), therefore the New Build property sector in particular new home developers, will need to also adopt renewable technologies. The committee on Climate change has indicated that by 2030 2.5 million air source heat pumps should be installed in UK new homes.

How to apply for the Renewable Heat Incentive Scheme

The Government requires a domestic Energy Performance Certificate (EPC) which is less than 24 months old and the installation must have been carried out by a Microgeneration Certification Scheme (MCS) accredited engineer.

Applicants must own or occupy the property where the technology has been installed.

Our packages include support on the application to the Renewable Heat Incentive Scheme which you must complete to get the invaluable RHI. If you need to renew your EPC, then this will cost approximately £60 to £120 but we can include this in your installation package.

You have 12 months to apply after the installation is complete and your technology with also be the Registered on the MCS database. Ofgem administers the scheme and further information can be accessed here.

To find out more, there is a very useful Mitsubishi Ecodan selection tool which provides an estimate of how an ASHP (Ecodan) can deliver heat to your home. The tool estimates

  • Annual running costs versus fuel types,
  • Carbon emissions,
  • Calculates the Payback period (the time taken to recoup the cost of the ASHP
  • Rate of return for an ASHP.


The Heat Pump ha s built in  meters to be MCS compliant, and these meters provide data to the ASHPs Application or Reporting tool so the homeowner can see some data on the performance. In certain situations for example where the property has an additional heating source additional meters are required . There are a number of different types of meter which we can advise you of.

The Metering and Monitoring Service Pack (MMSP) provides an extra RHI payment totalling £1,610 over the seven years although this meter is very expensive to buy and the cost can be in excess of £1k alone.  Under MMSP  the  RHI is paid on actual performance of the ASHP derived from the electricity used to generate heat
