Low carbon heating and hot water solutions are one of most impactful ways you can reduce your homes carbon emissions, with 31% of household emissions currently coming from central heating[₁], technologies such as heat pumps are one of the best ways to sustainably heat your home, lower your heating bills and reduce your carbon footprint. To further support the switch to renewables, there are two renewable incentives currently available in the UK;
What is RHI?
The RHI is a government scheme developed to promote the use of renewable heating system technology to help reduce the UK’s carbon emissions and meet the UK’s target of reaching net zero emissions by 2050.
Qualifying for the scheme means homeowners can receive regular payment contributions over a seven-year period. Homeowners can also benefit from fuel savings, courtesy of highly efficient renewable heating systems such as Vaillant’s heat pump range. The RHI will close to new applications in March 2022.
How much could you earn?
How much you can earn over the seven-year period depends on the type of heating system and the property age and size. To calculate the RHI funding on offer, homeowners must have an Energy Performance Certificate (EPC) less than two years old and as part of the installation the MCS accredited installer will conduct a MIS 3005 heat loss calculation. This is a room-by-room heat loss calculation taking into account the size of windows, the floor and ceiling type, how the walls are constructed and the type of doors in the property.
An EPC will also examine the status of other typical energy efficiency areas within the property, such as double glazing and loft and cavity wall installation which may help reduce the house’s overall energy consumption. To qualify for the RHI a minimum of 270mm loft insulation must be in place and any cavity wall construction must be internally insulated unless deemed exempt.
When do you receive the RHI payments?
Once the installation has been completed and commissioned by an MCS accredited installer, the installer will issue an MCS certificate and the homeowner can register the install online. Subject to eligibility the RHI payments will be paid every quarter for seven years.
Who is eligible?
All homeowners could be eligible for the RHI when retrofitting a heat pump, subject to the building having the appropriate measures and all relevant planning requirement being met. New build properties are not eligible unless they are self-build properties. To claim the RHI you must choose an MCS approved installer and the property must be in England, Scotland or Wales.

- EPC reference number – located on the top right of the first page of the EPC document
- The serial number of the heat meter fitted to the system if required – located on the calibration report for the heat meter
- The serial number of the electrical meter – located on the meter
- MCS installation certificate number – supplied by the installer Successful applications take approximately 30 minutes to complete. For more information go to: https://domesticrhi.ofgem.gov.uk/apply
