Who Qualifies for a Cavity Wall Insulation Grant in 2025? Eligibility Criteria Explained

With energy bills continuing to rise, many UK households are searching for ways to improve home efficiency and cut costs. One of the most effective solutions is cavity wall insulation — and thanks to government-backed initiatives like the Energy Company Obligation (ECO4) scheme, you may be able to get it installed for free or at a heavily reduced cost.

But who qualifies for a cavity wall insulation grant in 2025? In this blog, we’ll break down the latest eligibility criteria and explain how you can check if you’re entitled to one.

What Is a Cavity Wall Insulation Grant?

Before we jump into the qualifications, let’s quickly cover what these grants are. A cavity wall insulation grant is a form of financial assistance provided by the UK government and approved energy companies to help households insulate their homes. It’s part of an effort to reduce carbon emissions, combat fuel poverty, and improve energy efficiency in homes across the UK.

Under schemes like ECO4, eligible homeowners, tenants, and landlords can get their cavity walls professionally insulated without paying the full cost — in some cases, it’s completely free.

Who Qualifies for a Cavity Wall Insulation Grant in 2025?

The eligibility criteria for cavity wall insulation grants are based on several factors, including your income, benefits status, property type, and Energy Performance Certificate (EPC) rating. Let’s break it down:

✅ 1. You Receive Qualifying Benefits

If you or someone in your household claims certain government benefits, you’re likely to qualify for a grant. These benefits include:

• Universal Credit

• Pension Credit (Guarantee or Savings Credit)

• Income Support

• Income-based Jobseeker’s Allowance (JSA)

• Income-related Employment & Support Allowance (ESA)

• Housing Benefit

• Child Tax Credit

• Working Tax Credit

• Child Benefit (subject to income thresholds)

✅ 2. Your Household Income Is Below a Certain Threshold

Even if you’re not claiming benefits, you might still be eligible if your combined household income is under a specific threshold — typically under £31,000 per year, depending on the scheme and region.

✅ 3. Your Home’s EPC Rating Is D, E, F, or G

Cavity wall insulation grants are often targeted at properties with poor energy efficiency. If your home’s Energy Performance Certificate (EPC) rating is D or below, you may qualify for funding.

✅ 4. Your Property Type Is Suitable for Cavity Wall Insulation

Not every home can have cavity wall insulation. Your property needs to:

• Have unfilled cavity walls

• Be of a construction type suitable for insulation (e.g., not timber or steel-framed)

• Be structurally sound with no severe damp issues

A professional home survey will confirm whether your property is eligible.

✅ 5. Landlord Consent for Rented Properties

If you’re renting your home, you’ll need your landlord’s permission to apply for a cavity wall insulation grant. The good news is that many landlords support it since it boosts the property’s value and lowers tenant energy costs.
