The government is launching a new voucher scheme to support insulation improvement and heat pumps.
The scheme will be delivered to households through vouchers, available from the end of September. These will be through a central approved application portal. The vouchers will fund 2/3 of the cost of measures, up to the value of £5,000.
Companies delivering the measures must be MCS accredited or registered for TrustMark.
It will be possible to join the Renewable Heat Incentive (RHI) scheme after applying for the Green Homes Grant, allowing for grant recipients to have Green Homes Grant funding for the renewable heating system deducted from RHI payments. It is important to note that households are able to claim the Grant for energy efficiency measures both before and after accreditation to the RHI so if you are looking to install insulation as a primary measure you can also claim full RHI for your heat pump system. However, it is not possible to claim a Green Homes Grant voucher for your renewable heating system if you have already applied to the RHI or are receiving RHI payments.
The available measures are split into “primary” and “secondary” categories. Households will need to install at least one of the primary measures below to qualify for funding.
Insulation: Solid wall, cavity wall, under-floor, loft, flat roof, room in roof.
Low carbon heat: Ground source, water source and air source heat pumps.
“Top ups” are allowed (e.g. additional loft insulation up to the recommended level, solid wall insulation for other walls where a wall has been previously insulated), but replacements are not included.
So long as there is at least one primary measure in the package of works, households will also be able to install secondary measures. Secondary measures can only be subsidised up to the amount of subsidy provided for primary measures. (e.g. if a household receives £1,000 for primary measures, they can only receive a maximum of £1,000 towards secondary measures).
The secondary measures are:
• Draught proofing
• Windows and doors: Double/triple glazing (where replacing single glazing), secondary glazing (in addition to single glazing), upgrading to energy efficient doors (where replacing doors installed prior to 2002).
• Heating controls and insulation: appliance thermostats, hot water tank thermostats, hot water tank insulation, smart heating controls, zone controls, delayed start thermostat, thermostatic radiator valves
For low-carbon heating to be installed, households will need to have adequate insulation (e.g. wall and loft, where applicable). These can be installed as part of a package – they do not have to already be in situ.
The following properties are eligible:
• All owner-occupied homes (including long-leaseholders, shared ownership)
• Landlords of private rented sector domestic properties
New-build domestic properties and non-domestic properties are not eligible.
