Yes, you can still get free loft insulation in 2026. But time is running out.
The two main government-backed schemes are closing their doors soon. Applications for the Great British Insulation Scheme (GBIS) close on 31st January 2026. The Energy Company Obligation (ECO4) follows shortly after, ending on 31st March 2026.
If you've been putting this off, now is the time to act.
This guide breaks down exactly what's available, who qualifies, and what to do if you don't. No jargon. No confusion. Just the facts you need to make a decision.
The Two Main Schemes: GBIS and ECO4
Both schemes aim to help UK households reduce energy bills through improved insulation. They work slightly differently, but the goal is the same: get your home properly insulated at little or no cost.
Great British Insulation Scheme (GBIS)
GBIS targets homes with poor energy efficiency. It's designed to help both low-income households and those in "able-to-pay" groups living in inefficient properties.
The scheme covers loft insulation, cavity wall insulation, and other energy-saving measures. For eligible homeowners, the cost can be fully covered.
Key deadline: Applications close 31st January 2026.
Energy Company Obligation (ECO4)
ECO4 has been running longer. It requires large energy suppliers to fund home improvements for vulnerable and low-income households.
This scheme focuses on whole-house retrofits. Loft insulation is often a key part of the package.
Key deadline: ECO4 expires 31st March 2026.
Do You Qualify for Free Loft Insulation?
Eligibility depends on your circumstances and your property. You don't need to tick every box. Meeting one or more of the following criteria could make you eligible:
Personal Eligibility
- You receive government benefits : This includes Universal Credit, Pension Credit, Child Tax Credit, Housing Benefit, and others.
- You're a pensioner or over 70 : Age-related eligibility applies under certain conditions.
- You live in a lower council tax band : Bands A–D in England, or A–E in Scotland and Wales.
Property Eligibility
- Your home has an EPC rating below D : Properties rated E, F, or G are prioritised.
- Your current loft insulation is 100mm or less : The recommended depth is 270mm. If you're well below that, you likely qualify.
If you're a tenant, you'll need your landlord's written permission before applying. But don't let that stop you. Many landlords are happy to approve free improvements that add value to their property.
What Does the Grant Actually Cover?
For a typical 3-bedroom semi-detached home, loft insulation costs around £930. Through GBIS or ECO4, this can be partially or fully covered depending on your eligibility.
The grant pays for:
- Materials : Mineral wool, glass wool, or other approved insulation types.
- Installation : Carried out by certified professionals.
- Associated work : Clearing the loft, fitting loft boards in limited areas, and ensuring proper ventilation.
There's one important rule: grants only cover work done by PAS 2030–2035 certified installers. DIY work doesn't qualify. Neither does hiring an uncertified contractor.
This is where working with the right company matters.
What If You Don't Qualify?
Not everyone meets the criteria. And that's okay.
Maybe your household income is slightly above the threshold. Maybe your council tax band is too high. Maybe your EPC rating is already a D.
You still deserve quality insulation at a fair price.
At ComfySeal, we believe in transparent pricing with no hidden fees. If you don't qualify for a grant, we'll give you a clear, upfront quote. No surprises. No awkward conversations later.
We offer a range of insulation solutions to suit different budgets:

Whatever your situation, we'll find a solution that works.

What's Coming Next? The Warm Homes Plan
The government has announced a replacement scheme called the Warm Homes Plan. It's set to run for 3–5 years and will be administered by local authorities.
Details are still emerging. But the goal is to make grants more accessible for both on-gas and off-gas homes.
If you miss the current deadlines, this may be your next opportunity. We'll keep our customers informed as more information becomes available.
For now, though, the smart move is to act while GBIS and ECO4 are still open.
How to Apply

Why Loft Insulation Matters (Even If You Pay)
Grants are great. But even without one, loft insulation is one of the smartest investments you can make.
Here's why:
- Lower energy bills : A properly insulated loft can save you hundreds of pounds per year.
- Improved comfort : No more freezing bedrooms in winter or overheated rooms in summer.
- Higher property value : A better EPC rating makes your home more attractive to buyers and lenders.
- Reduced carbon footprint : Less energy wasted means a smaller environmental impact.
The payback period is typically just a few years. After that, it's pure savings.
Final Thoughts
Free loft insulation is still available in 2026. But the window is closing fast.
GBIS applications end on 31st January 2026. ECO4 follows on 31st March 2026. Once they're gone, you'll need to wait for the Warm Homes Plan: or pay out of pocket.
