In this guide, we’ll walk you through how cavity wall insulation grants work, who qualifies in 2025, and how you can start the process of securing your free upgrade today.

What Is a Cavity Wall Insulation Grant?

A cavity wall insulation grant is financial support provided by the UK government to help homeowners and tenants insulate the walls of their properties at no cost. These grants are part of the ECO4 scheme, which aims to make homes more energy-efficient and reduce fuel poverty across the UK.

If your home was built after 1920 and before the 1990s, there’s a good chance it has cavity walls — external walls with a gap between two layers of brick. Without insulation, that gap lets heat escape, causing you to spend more on heating your home.

Insulating those cavities means warmer rooms, less wasted energy, and lower heating bills.

Who Is Eligible for a Cavity Wall Insulation Grant in 2025?

The ECO4 scheme supports households most in need of energy-saving home improvements. Eligibility for insulation grants 2025 depends on a combination of household income, benefit status, and property type.

You may qualify if:

• You own or privately rent your home (with landlord permission).

• Your home has uninsulated cavity walls.

• Someone in your household receives benefits such as:

  • Pension Guarantee Credit

  • Universal Credit

  • Housing Benefit

  • Working or Child Tax Credits

  • Income Support

  • Income-based Jobseeker’s or Employment Support Allowance

Don't receive benefits? You might still qualify under LA Flex (Local Authority Flexible Eligibility) if your income is low, your property has a poor EPC rating, or you have a long-term health condition affected by the cold.

How Do Free Cavity Wall Insulation Grants Work?

Once approved, the grant covers the entire cost of the insulation installation — no hidden fees or upfront payments. Certified installers drill small holes in your external walls and inject insulation material (like mineral wool or polystyrene beads) to fill the cavity. The process is quick, clean, and non-invasive.
