Government Green Homes Grant offers subsidised energy-efficient home improvements for homeowners and landlords

Green Homes Grant

With the government’s launch of the £2bn Green Homes Grant to help homeowners and landlords in England and Wales make their homes more energy efficient and save money on their energy bills, we are optimistic that this will be a much-needed financial boost for households in Cornwall. The grant provides a greatly subsidised or 100% grant solution, with average savings from installing energy-efficient home improvements of up to £600/year per household.

The scheme launches on 30th September and provides householders with an opportunity to access grants for energy efficient home improvements.To find out more about the scheme, check eligibility and home improvement measures available, and to apply for a voucher, visit the government’s Simple Energy Advice service.

Who can apply?
As a homeowner or landlord, you can apply for a Green Homes Grant voucher and pay as little as a third of the cost of energy-efficient improvements up to a value of £5,000. So for every £1 you spend, the government will pay up to £2.

If you are a homeowner on a low income and receiving certain benefits, you need not pay anything at all, as the government will pay 100% of the costs, up to £10,000.

You qualify for the Green Homes Grant low-income scheme if you receive at least one of the following benefits:

  • Income based Jobseekers allowance (JSA)
  •  Income based Employment & Support Allowance (ESA)
  • Income Support (IS)
  • Pension Guarantee Credit
  • Working Tax Credit (WTC)
  • Child Tax Credits (CTC)
  • Universal Credit (UC)
  • Disability Living Allowance (DLA)
  • Personal Independence Payment (PIP)
  • Attendance Allowance
  • Carer’s Allowanc
  •  Severe Disablement Allowance
  •  Industrial Injuries Disablement Benefit
  • Contribution based Jobseekers allowance (JSA)
  • Contribution based Employment & Support Allowance (ESA)
  • Housing benefit

We understand that current circumstances might mean that spending money on making your home more energy-efficient is not priority at the moment. However, taking advantage of the Green Homes Grant scheme can save up to £600 per year on your energy bills, making life better month to month while you enjoy a warmer healthier home.

What improvements come under the voucher scheme?
At least one primary home insulation or low-carbon heating must be installed with your voucher.

Primary measures options available:

Cavity wall insulation

Room in roof insulation
Park Home insulation

Low-carbon heat (where the home is suitably insulated)
Air source heat pump

Once you have chosen to install at least one of the primary measures, your voucher can be used to help with the cost of secondary measures, if you wish.

Secondary measures options available:

Windows and doors

Secondary glazing (in addition to single glazing)

The amount the government will pay is capped according to the amount you have received for the primary measure(s). For example, if you have received £500 for a primary measure, such as cavity wall insulation, the maximum you will be able to receive for a secondary measure will be £500.

How do I apply for the voucher?

Green Homes Grant voucher applications can only be made online at the government’s Simple Energy Advice service. It is likely that this funding will be oversubscribed very quickly so we advise that you apply quickly to avoid disappointment.

To find out if you are eligible for a voucher and what improvements may be suitable for your home, please visit the government’s Simple Energy Advice service. You can also choose the improvements you would like and see an estimate of how much they may cost.

You will then need up to three quotes from TrustMark approved installers. For your nearest TrustMark approved tradesperson, go to or phone 0333 555 1234

Once you have decided on the improvements you would like to make and have your quote(s), then you can make an application on the government’s Simple Energy Advice service.

When does the work need to be completed and how is the work paid?
Based on the industry news we have seen so far, we understand that applicants will need to submit the quote(s) from their chosen installer as part of their grant application and the work will need to be completed before 31 March 2022 which is the extended phase of this programme. Once the work is complete the government will pay the installer the value of the voucher, however any shortfall in funding would need to be paid by the applicant to the installer before they start work. Vouchers will remain valid for 3 months and need to be redeemed before the end date on each one.
