Vouchers worth up to £5,000 will be issued to homeowners in England to make their homes more energy efficient under a new Government scheme that launches in September - here's what we know about the scheme after a new update on 4 August.

As part of the Green Homes Grant scheme, eligible homeowners will be able to use the vouchers to help pay for environmentally friendly improvements such as installing loft, floor and wall insulation or replacing single glazing with double-glazing. 

Chancellor Rishi Sunak outlined the plans, which will see the Government put aside £2 billion for green home upgrades, as part of his economic statement in July.

The Government has now released more details about what the vouchers will cover and who will be eligible. 

How will the Green Homes Grant work?

The idea is that the Government will give homeowners in England vouchers towards the cost of energy efficient improvements, which should cover much – and in some cases all – of the cost. You'll have to apply for a voucher once the scheme is up and running in September. You'll then be able to spend it to improve your home. 

The aim of the scheme is to help homeowners and promote energy efficiency, but also to help boost the economy during the coronavirus pandemic by creating jobs. 

The Green Homes Grant applies to England only – so unfortunately won't cover homes in Scotland, Wales or Northern Ireland (see advice for these areas later in the blog).

What will the vouchers cover?

After announcing that the vouchers could be used for roof and cavity wall insulation in July, the Government has now, in its 4 August update, confirmed the full list of improvements covered by the scheme. As expected, it is more complex than it originally appear
