How does the Green Grant work?
Well, to start with there are ‘primary’ and ‘secondary’ measures, these are:
Insulation is the primary measure, so either solid wall, cavity wall, under floor or loft. ‘Top up’ insulation can also apply to in these areas to meet the recommended requirements. It’s worth mentioning at this point that replacing a conservatory roof with a solid conservatory roof (although contains insulation) doesn’t quality in this category. More on this later.
The second primary measure is the installation of Low Carbon Heat, such as an air source heat pump, ground source heat pump or solar thermal.
One of these has to be installed first for you to be eligible.
Secondary measures can only be subsidised by the amount provides for the primary method. For example if a household receives £1000 for cavity wall insulation, then they can only receive a maximum of £1000 towards secondary measure.
This only applies if it remains within the allocated grant. For example, if £5000 is granted and £4000 is spent on a primary measure, then only £1000 remains available for the secondary measure.
So what classes as a secondary measure?
Heating controls and insulation such as appliance thermostats, hot water tank insulation, smart heating controls and draft proofing all apply.
Windows come into this category, but only if single glazing is being replaced with double or triple glazing. Double with double, or double with triple cannot be replaced . Doors also are eligible, but only if a door installed prior to 2002 is being upgraded.
