The Government's Green Homes Grant is one of its headline policies in looking to stimulate growth in the economy and provide jobs in the face of the continuing challenges of the coronavirus pandemic. 

What does the Green Homes Grant cover?

The Green Homes Grant has been created to help homes in England become more energy efficient and will issue vouchers to households which can be redeemed against measures thatboth bring renewable energy sources into homes and retrofit existing homes for better efficiency. 

According to the Department for Business, Energy and Industrial Strategy, these will be categorised into primary and secondary measures. 

The vouchers will be able to be spent on the following primary measures:

  • Solid wall, underfloor, cavity wall, loft, room in a roof, park home (see Trustmark for more information) or flat roof insulation 
  • Air source or ground source heat pump
  • Solar thermal
  • Biomass pellet hybrid heat pump

The secondary measures are made up of the following:

  • Double or triple glazing, or secondary glazing, when replacing single glazing
  • Draught-proofing 
  • Replacing and upgrading energy efficient doors
  • Hot water tank thermostats
  • Hot water tank insulation
  • Heating Controls (Smart heating controls, zone controls, intelligent delayed start thermostat and thermostatic radiator valves)

If you already have primary insulation measures in place, you can apply for grant money to improve them. You must apply for at least one primary measures as part of the Green Home Grant to be eligible for funding for the secondary measures.  

You cannot receive more funding for secondary measures than you do for primary ones – meaning if you claim £1,000 for insulation or a heat pump installation, you'll only be able to claim up to £1,000 for replacing windows in your property, for example.

How much money am I eligible to? 

The Government will pay two-thirds of the cost of energy-saving home improvements, up to the value of £5,000 per household. As an example, if the cost to install cavity wall and floor insulation in a semi-detached or end-of-terrace house was £4,000, the household would pay £1,320 and the Government would contribute £2,680 in vouchers. 

Low-income households are eligible for the Government to pay the full cost of improvements, up to the value of £10,000. If any member of the household receives a qualifying benefit the owner-occupier is eligible for the low income scheme. These include: 

• 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 Allowance • Severe Disablement Allowance • Industrial Injuries Disablement Benefit • Contribution based Jobseekers allowance (JSA) • Contribution based Employment & Support Allowance (ESA) • Housing benefit

At present, the scheme is only eligible for households in England, not Scotland, Wales or Northern Ireland. Find out more about schemes available in these regions through the Energy Saving Trust website

You are able to claim the Green Homes Grant alongside the Renewable Heat Incentive scheme where applicable; however, you must notify Ofgem and the value of the Green Homes Grant will be deducted from your RHI payments. You cannot receive funding from Energy Company Obligation (ECO) for the same measure as the Green Homes Grant. 

How to apply for the Green Homes Grant 

Homeowners in England can now access advice on improving their home’s energy efficiency from the Simple Energy Advice service, which will suggest which home improvements the Green Home Grant could fund for their property. 

This service will help you create a plan for your home, then offer a list of approved businesses who can carry out the work from their local area. You can download your plan, before contacting installers to get quotes for the improvements that you have selected. You'll need to keep a record of these quotes, as these will need to submitted as part of the application process.

Vouchers for the Green Homes Grant are now available through the Government's Green Homes Grant site.  The scheme is currently scheduled to run until March 2021, and all work will need to be completed before this deadline. 

Who can carry out the work?

The list provided to households will be made up of TrustMark registered businesses, including those approve via the Microgeneration Scheme (MCS). TrustMark is a Government Endorsed Quality Scheme, with Business and Energy Secretary Alok Sharma stating: “Our TrustMark scheme will guarantee that building work is completed to a high standard by accredited tradespeople, ensuring consumers are fully protected.”

Tradespeople who wish to be involved in the Green Homes Grant will have to register for TrustMark or get MCS accreditation.
