The Green Homes Grant: Get up to £5,000 for insulation and double glazing

By Matt Mostyn Thursday 01 October 2020

With the official launch of the Green Homes Grant on the 30th September, homeowners in England can now get up to £5,000 of vouchers to make some brilliant energy-saving home improvements. It’s all part of the UK Government’s new Green Homes Grant scheme, which is designed to help pay for a range of greener home upgrades.

It’s a big step in the right direction towards cutting our carbon emissions, saving us money and boosting the economic recovery after the coronavirus lockdown. We could do with a bit of good news after that particular curve-ball!

Here’s where you can find out everything you need to make the most of this new scheme, including details of what the Green Homes Grant is, what it covers, who’s eligible and how to apply. 

What is the Green Homes Grant?

The Green Homes Grant scheme helps homeowners and landlords in England to apply for some very useful money-saving and energy-saving vouchers. 

As the Government explains, the benefits will be far-reaching. Households could gain up to £600 a year in savings on energy bills, and the scheme should also help to support over 100,000 green jobs.1 

With the way we heat our homes accounting for 15% of the UK’s carbon emissions, the Green Homes Grant is a great initiative to help us kick  carbon into submission. And because we’re committed to reaching net-zero carbon emissions2 by 2030, as well as helping you to halve your own carbon footprint, we’re 100% on board! 

The vouchers are worth up to two-thirds of the cost of making your home more energy efficient. For most people, the maximum contribution will be £5,000 – but households on low incomes will be eligible for up to 100% funding, up to a maximum of £10,000.

600,000 people could benefit from the Government’s new scheme – which is part of a £3bn wider investment in green technology to help us shrink our impact, reduce our emissions and lighten our carbon footprint.

What does the Green Homes Grant scheme cover? What improvements can I get?

The grant covers a selection of key energy-saving home improvements, and the measures are split into two parts – primary and secondary.

Of course, there are a couple of rules involved for anyone who wants to qualify. As part of the deal, you need to carry out at least one of the primary measures before you can qualify for the secondary ones. 

On top of that, the secondary measures mustn’t cost more than the primary one(s).

Here’s a list of the included measures:

Primary measures

Under the scheme, you can choose one or more of the following:

Secondary measures

Once you’ve carried out a primary measure, you can then choose one or more of the following:

  • Double glazing, triple glazing, and secondary glazing (if upgrading from single glazing)

  • Upgrades to energy-efficient doors (for example, replacement of doors fitted before 2002)

  • Draught-proofing

  • Hot water tank/appliance tank thermostats/heating controls, as well as thermostatic radiator valves, smart heating controls, or zone controls

What isn’t covered by the Green Homes Grant scheme?

It’s been confirmed that new-build homes and all non-domestic properties – for example, commercial premises – won’t qualify for the green home vouchers.

If you’re eligible, you can only get funding for the secondary improvements up to the amount of funding you're receiving for the primary measures. 

So for example, if you've been given £1,000 towards cavity wall and roof insulation, you can only receive up to £1,000 towards any secondary measures, like double glazing or thermostats. 

As for suppliers, only accredited suppliers can quote on and do the work. TrustMark Registered Business or MCS Certified tradespeople count as an accredited supplier under the Green Homes Grant scheme. Installers will also need to follow additional requirements, so be sure to check with them.

How do I know what work I need in my home?

Air source heat pumps, solar thermal energy, low emissivity glass. Sometimes energy-efficient home improvements can sound like a foreign language – especially to the uninitiated! If you’re not sure where to begin doing energy-saving work in your home, there are a few good places to start.

First of all, you could check out our online energy guides. These cover a range of topics, and will give you the lowdown on everything from air source heat pumps and the world’s best low carbon heating options, to smart home technology, eco-boilers and the easy ways to reduce your carbon footprint

There’s also a brilliant online resource called Simple Energy Advice. It’s a Government-endorsed website that offers advice on this scheme, as well as impartial, independent advice on everything from planning new home improvements to making your home greener.

How much is the Green Homes Grant?

For most homeowners, Green Homes Grant vouchers will be worth about two-thirds of the cost of the improvements – up to a maximum of £5,000 per household. 

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.

Who can apply for the Green Homes Grant?

The Government has confirmed that all owner-occupied homes (including long-leaseholders and shared ownership properties) will be eligible to use the general £5,000 voucher scheme.

Landlords of private rented and social domestic housing can also use the scheme, along with park home owners. 

Leaseholders, and those with a share-of-freehold type lease will likely need to get permission from the (other) freeholder(s) before making any changes that affect the building.

When is the Green Homes Grant available?

The Green Homes Grant launched in September 2020, and at this stage it will run until March 2021. 

It’s currently not 100% clear if this will be the end of the scheme. For instance, applications made before the deadline may or may not be implemented after the closing date – and a new scheme may perhaps take its place after this one.

The UK's annual carbon emissions in 2019 were 351.5 million tonnes of CO2 (excluding other greenhouse gases) according to provisional BEIS data (published March 2020, available at: https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/875485/2019_UK_greenhouse_gas_emissions_provisional_figures_statistical_release.pdf). 39 million tonnes of CO2 is about 11% of the UK's 2019 carbon emissions.
