Green Homes Grant for Homeowners

What are the benefits of doing green home improvements?

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.

What are the primary and secondary measures? 

The available measures are split into ‘primary’ and ‘secondary’ categories. Households will need to install at least one of the qualifying primary measures to be able to use the voucher on any secondary measures. The secondary measure will be subsidised up to the subsidy value of the primary measure, e.g. if a household receives £1,000 for primary measures, they will receive a maximum of £1,000 towards the secondary.

Primary measures


  • solid wall, cavity wall, under-floor, loft, flat roof, room in roof, and park home insulation.

Low carbon heat: 

  • air source heat pump, ground source heat pump, solar thermal, and biomass pellet boilers.

Secondary measures

Windows and doors: 

  • draught proofing, double/triple glazing (where replacing single glazing), secondary glazing (in addition to single glazing), and energy efficient replacement doors. 

Heating controls and insulation: 

  • hot water tank thermostats, hot water tank insulation, heating controls to include: smart heating controls, zone controls, delayed start thermostat, and thermostatic radiator valves.


Getting the voucher

You should receive a separate voucher for each measure that you apply for. Each voucher will be valid for up to 3 months from the date of issue, and must be used by the named person and registered household that applied for it.
Installation can only commence once the voucher has been issued, and won’t apply to any work started before then.

You can request an extension to your voucher, any time before it expires. You will not be able to extend the validity of your voucher after the scheme ends.


Getting the work done

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.


What to do after the work is complete and how to redeem your voucher
