Check insulation grants and home insulation options
Insulating your home is one of the most effective ways to cut bills and improve comfort. This hub explains the main insulation types, who may qualify for support and how to check your options.
Why insulation matters
A poorly insulated home loses heat through the roof, walls and floors. Adding insulation reduces heat loss, lowers energy use and can significantly improve EPC ratings.
Loft insulation grants
Loft insulation top-ups to current standards are commonly funded under ECO4 and the Great British Insulation Scheme. It is one of the most cost-effective upgrades for many homes.
Cavity wall insulation grants
Cavity wall insulation may be available where the property has unfilled cavities and is suitable for treatment. A surveyor will confirm suitability before installation.
Solid wall insulation grants
Solid wall insulation (internal or external) is often the most expensive measure. ECO4 and Warm Homes routes may contribute, with householder contributions sometimes required.
Who may qualify for insulation support?
- Homes with EPC D-G
- Households on lower incomes or qualifying benefits
- Vulnerable occupants under local authority flexible eligibility
- Tenants (with landlord permission) and social tenants via providers
EPC and income considerations
Schemes typically combine property efficiency (EPC) with household circumstances (income, benefits, vulnerability). The best route varies by region and council.

Frequently asked questions
Is insulation always free?
Not always. Some measures may be fully funded for eligible households; others require a contribution. An approved installer can confirm.
Can tenants apply for insulation grants?
Yes, with the landlord’s permission in most cases. Some schemes are designed to be tenant-led; social tenants typically access support via their housing provider.
Does my home need a survey first?
Yes. An accredited installer or surveyor will check suitability for the specific insulation type before any work is approved.
Will insulation cause damp?
Properly specified and installed insulation should not cause damp. A retrofit assessment considers ventilation alongside the insulation measures.
Which insulation gives the biggest saving?
For most uninsulated homes, loft and cavity wall insulation deliver the largest immediate savings. Solid wall insulation is more expensive but impactful for older homes.
