Measures confirmed for new Green Homes Grant Scheme

The full list of measures for the impending Green Homes Grant Scheme has now been confirmed by BEIS.

The measures fall into two categories – primary and secondary.

For households to qualify for secondary measures they must install at least one of the primary measures.

Primary Measures

The primary measures that homeowners must install to be eligible for secondary measures funding are:

  • Insulation (solid wall, cavity wall, under-floor, loft, flat roof, room in roof, park home)
  • Low carbon heat (air source heat pump, ground source heat pump, solar thermal)

It has also been confirmed that “top-ups” are allowed. For example, this would be solid wall insulation for other walls where a wall has been previously insulated. Replacements are not included.

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. Households will need to have adequate insulation for low-carbon heating to be installed.

It is important to note that secondary measures can only be subsidised up to the amount of subsidy provided for primary measures. For example, if a household receives £2,000 for primary measures, they can then only receive the same (a maximum of £2,000) towards any secondary measures.

Want to install under the Green Homes Grant Scheme?

Quality assurance is at the heart of the Green Homes Grants scheme and the government has now clarified that tradespeople who want to install under the scheme must be TrustMark accredited, and also, MCS certified for heat pump installations and solar thermal.
