Green Homes Grants


From the end of this month, homeowners and landlords will be able to apply for Green Homes Grants of up to £5,000 to pay for environmentally friendly and energy efficient home improvements that will help save on energy bills and keep homes warm during winter.


There are however restrictions on what improvements can be made to qualify for the grants and the vouchers will only cover up to two-thirds of the cost of qualifying works. Those on lower incomes may be eligible for the full cost of improvements under the scheme up to £10,000.

There are two categories of measures allowed under the scheme:

Primary measures include:


Insulation of walls and roofs

  • Solid wall

  • Cavity wall

  • Under-floor insulation (solid floor; suspended floor)

  • Loft

  • Flat roof

  • Room in roof

  • Park home insulation

Low carbon heat (when insulated to a certain level)

  • Air source heat pump

  • Ground source heat pump

  • Solar thermal

  • Biomass pellet boilers

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 (replacing single glazed or solid doors installed before 2002)

Heating controls and insulation

  • Hot water tank thermostats

  • Hot water tank insulation

  • Heating controls (e.g. smart heating controls, zone controls, intelligent delayed start thermostat and thermostatic radiator valves)

‘Secondary’ measures will only be funded alongside 'primary’ measures, and the amount offered for secondary ones will be capped at that offered for a primary one. It is worth keeping in mind that these grants are only for new measures, and can’t be used to update existing insulation or double glazing, for example. New extensions, converting your home, insulating a conservatory with no fixed heating or installing a new fossil fuel boiler are also not covered.


Before applying, you will need to check whether you are eligible for a voucher and whether the improvements may be suitable for your home. It is advisable to research the available options carefully to check whether your home would benefit. Check on the Simple Energy Advice (SEA) website for more details and to find SEA accredited tradespeople to quote for eligible work. They advise obtaining at least 3 quotations for the intended work.


By the end of September, you will be apply for the voucher via the Government website and when your application has been approved, work can then be commissioned using one of the above accredited tradespeople. Vouchers must be redeemed and all the intended work completed by 31st March 2021.
