What Is the Free Home Insulation Grant
The Free Home Insulation Grant UK, part of the ECO4 and Great British Insulation Scheme, provides 100% funded loft, cavity wall, solid wall, and floor insulation to eligible households. Aimed at reducing heat loss and tackling fuel poverty, this government-backed program covers installation costs—typically £200–£500 savings per year—ensuring warmer homes and lower bills.
This initiative addresses the UK's commitment to carbon reduction while helping households most affected by rising energy costs. All installations are performed by certified professionals following PAS 2035 standards, the government's specification for whole-house retrofit projects.
Who Qualifies
The Free Home Insulation Grant UK targets households most in need of energy efficiency improvements:
- Households on qualifying benefits (Universal Credit, Pension Credit, etc.)
- Homes with EPC ratings D, E, F or G needing insulation upgrades
- Homeowners and private tenants (with landlord consent)
- Targeted local authority or FLEX areas may extend to moderate incomes
By focusing on low-income and inefficient homes, the grant maximizes impact on energy savings and carbon reduction.
