- Internal Wall Insulation – Available for terraced houses, small semi-detached homes and bungalows.
How do you qualify for a Great British Insulation Scheme grant in Wales?
There are 2 routes to qualifying for a Great British Insulation grant.
- The General Group.
- The “low-income” Group.
The General Group qualification for a Great British Insulation Scheme grant in Wales.
You need to say Yes to the following 2 questions to qualify.
- Is your Council Tax Banding in Wales an A, B, C, D or E (or in England A to D)? If you don’t know, you can find your Council Tax Banding on Gov.Uk, and
- Is your EPC (Energy Performance Certificate) rating a D, E, F or G.? You can find your EPC on the EPC Register. Don’t worry if your property doesn’t have an EPC – we can take care of that.
2 yeses and you qualify.
These rules apply to both owner-occupiers and privately renting tenants.
However, the Government have decided that if you are a privately renting tenant and you want cavity wall insulation or loft insulation you will need to receive a qualifying benefit. You will not require a qualifying benefit if you want Internal Wall Insulation.
The “Low Income” Group qualification for a Great British Insulation Scheme grant.
The personal qualification criteria for the “low income” group is that you are in receipt of a qualifying Government Benefit. Your EPC (Energy Performance Certificate) must still be a D, E, F or G rating.
