The latest information on the Government’s Green Homes Grant for insulation and low carbon heating in England.

Back in July Chancellor Rishi Sunak announced a new energy-saving initiative, the Green Homes Grant, which will see homeowners in England receive up to £5,000 towards insulation for their properties. It comes as part of a wider £3 billion package to help the UK meet its 2050 target of achieving net zero carbon emissions, and aims to support more than 100,000 green jobs and upgrade 600,000 homes across England. The scheme is now open, and the government has shared more details about the scheme, who’s eligible, and what improvements will be covered by the vouchers.

Here’s everything you need to know.

What improvements can I get through the Green Homes Grant?

Qualifying improvements are split into two categories: primary measures and secondary measures. You must choose at least one primary measure, such as insulation or renewable heating, and then you can use the voucher to help cover the cost of secondary measures, such as draft proofing or double glazing.

The subsidy for the secondary measure is capped at the value of the subsidy provided for the primary measures. For example, if you receive £400 for a primary measure, such as cavity wall insulation, you will be able to receive a maximum of £400 for a secondary measure, such as an energy efficient replacement door.

How do I apply for the Green Homes Grant?

Click here to get started. You'll need the following information to hand:

  • The name and date of birth of the property owner
  • The name and date of birth of anyone living in the property that receives benefits
  • A quote for the work from a TrustMark-registered tradesperson
  • The TrustMark license number of your chosen tradesperson

How do I find a registered tradesperson?

Use the scheme’s official online tool on the Simple Energy Advice website to check your eligibility, learn about the improvements best suited to your home, get an estimate of costs, and find accredited tradespeople to contact for quotes. 

What happens if I’m claiming other energy-related grants or funding?

There are two initiatives that could be impacted by the Green Home Grant.

Energy Company Obligation

According to Simple Energy Advice, you will not be able to claim Green Homes Grant subsidy vouchers towards the cost of a measure which has also received funding under the Energy Company Obligation (ECO). However, you can claim both ECO and Green Homes Grant subsidy providing they are each for different measures – for example loft insulation and cavity wall insulation.

Renewable Heat Incentive

The Domestic Renewable Heat Incentive (RHI) gives households money towards renewable heating costs in their home. Payments are made for seven years and are based on the amount of renewable heat made by your heating system.

Simple Energy Advice says that you’ll be able to claim both the Domestic RHI and the Green Home Grant for the renewable heat installation. You must claim the Green Home Grant first and then notify Ofgem that you have used it when you apply for accreditation to the Domestic RHI. The Green Homes Grant will then be deducted from your Domestic RHI payments.

Households can claim the Green Homes Grant for energy efficiency measures both before and after accreditation to the Domestic RHI.
