Grants and incentives

There are many reasons to consider installing low carbon technology in your home or community. However to promote the uptake of small-scale renewable and low-carbon technologies, there are a range of incentives and grants available.

Your eligibility may be dependent on where you live and the technology type.

MCS certification is a route for consumers to access incentives. Before progressing with any installation, you should always check that your Installer is MCS certified and using MCS certified products. You can check this in our Installer search.


THE UK government announced new laws that will ensure households and businesses with small-scale renewable technologies, are paid for exporting their excess electricity to the grid.

This new scheme will allow solar PV owners to continue earning from their solar system’s generation.

The Smart Export Guarantee requires medium – large electricity supply companies (those with more than 150,000 electricity customers) to offer a Smart Export Guarantee (SEG). Smaller suppliers can do so on a voluntary basis.



The Green Homes Grant is a £2 billion government-funded voucher scheme designed to help with the installation of energy efficiency measures on homes in England to reduce energy bills and carbon emissions.

The voucher of up to £5,000 will cover at least two thirds of the cost of some energy-saving home improvements. Some homeowners on qualifying benefits can get a voucher for up to £10,000 towards the cost of these home improvements.

Low carbon heating including Air Source Heat Pumps, Ground/Water Source Heat Pumps, Solar Thermal and Biomass Boilers are included in the Green Homes Grant scheme as primary measures. To be eligible for a voucher, the low carbon heating must be installed by an MCS certified Contractor who is also TrustMark approved.

The scheme launched on 30 September 2020 and closes at the end of March 2021.

The Renewable Heat Incentive (RHI) is a government backed financial incentive scheme designed to encourage UK homes to swap to renewable heating systems. Under the RHI, heat pump system owners are rewarded for the renewable heat they generate over a seven year period.

How do RHI payments work?

After joining the RHI scheme, you receive a quarterly tariff payment for every kilowatt hour (kWh) of renewable heat you produce. You get these payments for seven years. It’s possible for households to install more than one technology and receive payments for each system they use.
