Green Homes Grant – how they work and how to apply

Here's how the Green Homes Grant works, including latest details of which energy efficiency measures are covered, advice on which projects to undertake and how to find a tradesperson

Post updated: October 15th, 2020

Green Home Grants

In July the Chancellor announced that homeowners will be able to claim vouchers of up to £5,000 for energy-saving home improvements, with the poorest getting up to £10,000.

As part of a £2 billion Green Homes Grant announced for England, eligible homeowners will be able to use the vouchers to pay for environmentally friendly improvements.

But if you were hoping to be able to access your £5,000 voucher and spend it on the home improvements of your choice, you may be disappointed.

How will the vouchers work?

Restrictions mean that energy efficiency measures permitted under the scheme are being divided into two categories: “primary” and “secondary”.

In order to qualify for funding to cover secondary measures, home owners must first carry out one of the primary measures.

And, the amount of money offered by the government for secondary measures is capped at the amount the home owner claimed for primary improvements. So if you receive £1,000 towards primary upgrades, your grant for any secondary measures will be capped at £1,000.

How much can I get?

The government will provide a voucher that covers two-thirds of the cost of qualifying works to your home. The maximum value of the voucher is £5,000.

If you are on a low income and receive certain benefits, you can receive a voucher covering all of the cost of the improvements up to £10,000. A full list of qualifying benefits are available on the Simple Energy Advice website.

The installer will request and receive payment from the government for the costs covered by the voucher.

When can I get works done under the scheme?

You can apply for the voucher from 30 September 2020.

In the meantime, you can find out what improvements can be made to your home and obtain quotes from certified tradespeople.

You must redeem the voucher and ensure improvements are completed by 31 March 2021.

What energy efficiency measures are covered by the Green Homes Grant?

The list of primary measures are set out as:


  • Solid wall insulation
  • Cavity wall insulation
  • Under-floor insulation
  • Loft insulation
  • Flat roof insulation
  • Room in a roof insulation
  • Park home insulation

Low carbon heat (where the home is suitably insulated)

  • Air source heat pump
  • Ground source heat pump
  • Solar thermal
  • Biomass pellet boilers

So long as at least one of these primary measure is in the package of works, households will also be able to install secondary measures.

The list of secondary measures include:

Windows and Doors

  • Draught proofing
  • Double/triple glazing (where replacing single glazing)
  • Secondary glazing (in addition to single glazing)
  • Energy efficient replacement doors

Heating controls and insulation

  • Hot-water tank thermostats
  • Hot water tank insulation
  • Heating controls (Smart heating controls, zone controls, intelligent delayed start thermostat and thermostatic radiator valves)

What home improvements should I do?

The first place to start is understanding whether your home is in need of any of the primary measures. Air source heat pumps and biomass pellet boilers are no doubt improvements most households will not have heard of, let alone understand, so these projects will need to be thoroughly researched first.

Cavity and solid wall insulation can make a significant difference to the energy efficiency and comfort of your home.  We expect these will be popular projects to undertake, alongside loft and other insulations, to stop heat leaking from your home.

Once you have identified at least 1 primary measure, your voucher can be used to help contribute to the cost of a secondary measure. Replacing single glazing or getting secondary glazing will make the most difference if you don’t already have double glazing. Please note you can’t upgrade existing double glazing under the scheme. And you can’t use the voucher to update existing insulation in your home.

And remember, the amount you get towards the cost of secondary measures cannot exceed the amount you get for primary measures.

Use the Simple Energy Advice (SEA) website to get more details and check what energy efficiency or low carbon heat improvements can be made to your home.

How do I find a tradesperson and start works?

You will need to have the works done by a tradesperson registered with TrustMark or Microgeneration Certification Scheme (MCS), who are accredited to take part in the Green Homes Grant voucher scheme.

Use the Simple Energy Advice (SEA) website to find accredited tradespeople or businesses in your area that are able to undertake the work and obtain quotes from them.

You should get at least 3 quotes to make sure you are getting the best value for money.

Speak to all of them to see what home improvements they would recommend.

Once the works are agreed, vouchers can be issued from the 30th September online, so work can commence.

With most good tradespeople booked-up well in advance, we’d suggest getting on with it!

Watch out for scammers

You can’t necessarily use your local builder to install your chosen works under the Green Homes Grant scheme. You need to use firms registered with the Microgeneration Certification Scheme (MCS) or Trustmark.

Within days of the government scheme being announced, homeowners started to receive scam emails and phone calls. Do not respond to unsolicited emails and calls about the scheme.

How do I apply for the Green Homes Grant

You need to take the lead in applying for the Green Homes Grant yourself, although your installer will claim the voucher. To recap, you need to:

  1. Identify the qualifying projects you would like to undertake. See the Simple Energy Advice (SEA) website to help you with this.
  2. Find a registered installer/installers. You can use the Simple Energy Advice (SEA) website or go to Trustmark or the MCS direct.
  3. Get a detailed quote before works start. The registered installer will need to claim the voucher for a third of the costs from government. Their quote should include this sum for transparency and you should talk about how the scheme works with them in detail so there aren’t any unexpected costs at the end.

Lower bills, lower emissions

The government said if a homeowner of a semi-detached or end-terrace installed cavity wall and floor insulation, costing around £4,000, the homeowner would pay just £1,320 – with the government paying £2,680. Doing so could save the owner over £200 annually on their bills and reduce their carbon footprint by cutting 700 kg of CO2 a year from their home alone.

The scheme aims to upgrade over 600,000 homes across England.

Better insulation could save some people £600 a year on energy bills.

Funding is only currently available until March 2021.

  1. Are Listed buildings exempt? The age range of the properties in the application suggests they will not be approved although surely they are the most inefficient of most homes out there?

    I have a conservatory roof which leaks and is extremely cold in the winter and difficult to heat. I am am looking at trying to replace it as I also use it as a bedroom and it really is unbearable. Any advice or help would be greatly appreciated.

  7. There are some really stupid comments on here. Why can’t people be bothered to do their own research on the government’s site?

    Comment by Paul — September 30, 2020 @ 11:16 pm

  8. Hi,

    We have just purchased an old cottage to which is in urgent need of roof insulation. We were hoping to take advantage of the Green Grant Scheme but unfortunately we have been notified that there is evidence of bats in the loft space.

    Due to the next phase of bat assessment/survey, which is not able to take place until June, the loft space is currently rendered inaccessible to do any work and take advantage of the grant. Is there any way we can get around this as we will miss the March deadline through circumstances out of our control?

    Comment by Graham Stewart — September 12, 2020 @ 2:29 pm

  16. I live on my own & I am on income support, do come under this government scheme I have my own home .

    Comment by Pauline Heather — September 12, 2020 @ 12:19 pm

  17. It seems that, from current information on the simpleenergyadvice website, in order to access the funding the work MUST be carried out by one of their approved installers.
    There appear to be very, very few of these. Entering my postcode in mid Yorkshire produces just 22 companies that are authorised to fit double glazing let alone the ones actually covered by the grants. Yes, that’s 22 in the whole of England. Seriously?
    It seems that the website is in error as it only returns results for me that are based around Leeds. There are no other companies shown for the rest of the UK but I guarantee they exist. This will make it practically impossible to obtain quotes that would be eligible for the grants. It needs sorting urgently.

  26. I would like to get some of the secondary measures installed (replacement double glazing), we got some of the secondary measures installed last year (insulation).

    I wonder if this previous work will allow us to qualify for the grant for the secondary measures or does the work have to all begin after September 2020?

  31. Our double glazing is completely worn out. It is aluminium and probably around 40 years old. Virtually every room has a problem with the window. One window is nearly falling off. We have it shut permanently. The list is long for other problems like not staying open or steamed up inside glazing.

  66. Does the grant cover solar panels.

    Comment by Christine — July 15, 2020 @ 1:57 pm

  67. We all hope the details will be announced well in advance to allow people time to prepare. Last time around the property had to have an EPC less than a year old confirmimg what energy saving measures the property needs and the “grant” was actually a cashback so homeowners had to be able to fund the whole cost themselves then get the cash back. So this time around we need a simpler and better consumer focused process.

    Comment by ann moyies — July 9, 2020 @ 11:05 pm

  80. As always without the detail no policy is actually defined. I remember a precious incarnation of green grants that saw us get a surveyor travel several hundred miles ( ie not green) to survey and months later be told we had 10mm too Loft insulation much to qualify. Windows had to have their appalling retrofit draft exclusion which we refused as it would probably have caused us listed building issues. Let us hope that there is flexibility in this scheme and it is all not simply absorbed by over restrictive guidance or too small a group of companies that are accredited. What was wrong with simply taking VAT off green improvement products. Will boilers be included. What was wrong with actual kickstarting green infrastructure like electric car charger installations etc. I await the detail and sincerely hope our civil service has learnt from past implementation and guidance mistakes.
