Green Homes Grant


What is the Green Homes Grant? 

Earlier this year, the Government launched its £2 billion Green Homes Grant scheme. This scheme allows people to make energy improvements to their homes.  

This offers homeowners and residential landlords the chance to apply for vouchers to put towards the cost of making energy-efficient improvements to their property. A 1-year extension for the Green Homes Grant has been announced on the 18th November by the Department for Business, Energy & Industrial Strategy, until the end of March 2022. 

The scheme allows homeowners across England to claim vouchers to cover two-thirds of the cost of eligible improvements up to £5,000, or 100% of the cost for homeowners on low incomes, up to £10,000. Measures covered include insulation of walls, floors and roofs, double or triple glazing when replacing single glazing, and lo-carbon heating like heat pumps.   

Housing estate


You may be eligible if you live in England and: 

• You own your own home (including long-leaseholders and shared ownership) 
• You own your own park home on a residential site (including Traveller sites) 
• You’re a residential landlord in the private or social rented sector (including local authorities and housing associations) 

You cannot get the Green Homes Grant for newly built homes which have not been previously occupied.


How Much Can You Get? 

Vouchers will cover 2/3s of the cost of eligible improvements, up to a maximum government contribution of £5,000.  

If you, or someone in your household, receive certain benefits you may be eligible for a voucher covering 100% of improvement costs. The maximum value of the voucher however is £10,000. 


What Can The Voucher Be Used For?

It is recommended that you seek advice on how best to improve energy efficiency and heating in your home. You can use the Simple Energy Advice (SEA) website to check what energy efficiency or low carbon heating improvements may be best suited to your home.

Getting work done during national restrictions 

Tradespeople, including Green Homes Grant installers, can continue to work in people’s homes under the national restrictions from 5 November. You can still apply for a grant and get the work done. Your installer will follow the COVID-19 Secure guidelines.  If you would prefer, to minimise contact during national restrictions, you can ask your installer to provide a quote remotely using a video call or detailed photos. For further guidance on how to protect yourself and your tradesperson while getting work done during coronavirus, visit the TrustMark Work Safe, Safe Work website. You can still apply for a grant and get the work done.

The aim of the scheme is to cut carbon dioxide production and help homeowners reduce their energy bills - this could mean a generous saving of up to £600 a year. Homes will be made warmer and more energy-efficient, which will go a long way towards a green recovery and a cleaner environment. The additional benefit will give much-needed support to over 100,000 jobs in the industry. 

Your chosen installer can commence work once your voucher has been issued. You may be asked to pay a deposit before any work starts - this will be no more than you would normally pay a tradesperson, and will not exceed your contribution amount of the measure under this scheme.


Tradespeople and businesses that are appropriately certified to install energy efficiency and/or low carbon heating improvements in homes need to register with TrustMarkto carry out work under the scheme. This confirms to homeowners that you will install measures to high standards. 

You will be added to a directory of TrustMark registered  installers and homeowners can then contact you to obtain a quote. 

Tradespeople and businesses that install low carbon heating improvements in homes will also need to be MCS certified. 

Once you are registered with TrustMark, you need to apply to become a Green Homes Grant installer so you can deliver work in the 600,000 homes that will receive vouchers. 


Key Points

1. The PM’s extension for the Green Homes Grant is until the end of March 2022 for the £1.5 billion voucher element, and until the end of December 2021 for the £500 million Local Authority Delivery element. 
2. Green Homes Grant vouchers remain valid for 3 months from the date they are issued or until 31 March 2022, whichever is earlier, and need to be redeemed before the end date on each one. Homeowners can request an extension for circumstances outside of their control.  
3. Homeowners (both freehold and leasehold owner-occupiers), and landlords can apply for vouchers of up to £5,000 towards the cost of installing energy-efficient and low-carbon heating improvements in their homes. Some homeowners on income-based or disability benefits may be eligible for vouchers covering the full cost of improvement, up to a value of £10,000.  
4. There are 2 elements to the scheme, a voucher scheme available to all homeowners and domestic landlords and a Local Authority Delivery scheme, through which funding will be allocated to local authorities to support lo-income, fuel poor households.  
5. Vouchers will help more than 600,000 households across England to save up to £600 a year on energy bills, whilst both elements of the scheme supporting 100,000 jobs in green construction and helping the UK to reach net-zero carbon emissions by 2050. 
6. Tradespeople need to be TrustMark registered and have a Microgeneration Certification Scheme or Publicly Accessible Standards certification to carry out these home improvements as part of the scheme. This will assure homeowners that tradespeople have been thoroughly vetted and meet the required standards of good customer service, technical competence and good trading practices.
