To register as a Green Homes Grant Scheme Installer, the installer must first be certified with Trustmark for each type of measure they wish to install.
To get Trustmark certification the installer should already be installing under PAS2030 or PAS 2035 standards and should talk to their industry certification body, or another Trustmark Scheme Provider, and they will help them register with Trustmark.
For low-carbon / renewable heat measures such as Air Source Heat Pumps, Ground/Water Source Heat Pumps, Solar Thermal and Biomass Boilers the installer must also be an MCS certified Contractor.
Once they have a Trustmark registration number the installer can then apply online
to the Green Homes Grant Scheme Administrator for registration with the scheme.
If installers don't register with the Scheme Administrator before the customer applies for the voucher, the installer may have issues getting the voucher reimbursed.
