Green Homes Grant

What is the Green Homes Grant?

Homeowners and landlords in England can apply for a voucher towards the cost of installing energy-efficient and low-carbon heating improvements to homes, which could help save up to £600 a year on energy bills.

The government will provide a voucher that covers up to two-thirds of the cost of qualifying improvements to your home. The maximum value of the voucher is £5,000. You may be able to receive a higher level of subsidy if you are a homeowner and either you or a member of your household receives one of the qualifying means-tested benefits, covering 100% of the cost of the improvements. The maximum value of these vouchers is £10,000. Landlords cannot apply for the low-income part of the scheme

How It Would Work?

As an example, a homeowner installing cavity wall and floor insulation costing £4,000 would only pay about £1,320. The Government will contribute the remaining £2,680 through the voucher scheme.
Those on low incomes will be able to get more. In that case, the Government will cover the full cost of the energy-efficient improvements, so you won't have to pay anything – and the vouchers could be worth up to £10,000 per household.
Local Authorities will also be making support available for low-income households in their local area through the Green Homes Grant: Local Authority Delivery. More information on participating Local Authorities will be made available on GOV.UK in due course.

What improvements can you get?

Vouchers must be used to install at least one primary home insulation or low carbon heating measure.
If you choose to install at least one of the primary measures, you can use your voucher to help cover the cost of secondary measures. 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 a cavity wall insulation, you will be able to receive a maximum of £400 for a secondary measure such as an energy-efficient replacement door.

The primary and secondary measures are set out below:
