Free Loft Insulation Grants in 2026
Free loft insulation grants in 2026 are available through ECO4 and the Warm Homes Local Grant for low-income households in the UK. Uninsulated homes lose around 25% of heat through the roof. Loft insulation takes 1–2 hours to install and can save approximately £355 per year on energy bills.
Loft insulation is one of the easiest energy upgrades you can make to your home. It takes a couple of hours, causes almost no disruption — whether you're in Birmingham or the Scottish Highlands — and an uninsulated home loses around 25% of its heat through the roof. If you're on a low income or receive certain benefits, you can get it done completely free.
Two government schemes currently fund free loft insulation: ECO4 (closing December 2026) and the Warm Homes: Local Grant. Here's how to find out if you qualify.
Could you get free loft insulation?

The savings depend on your current insulation levels. According to the Energy Saving Trust:
- An uninsulated home loses around 25% of its heat through the roof
- Topping up from 120mm to the recommended 270mm can save around £20 per year
- Installing from scratch (0 to 270mm) saves significantly more, as you're eliminating a major source of heat loss
- Loft insulation lasts around 40 years with no maintenance, so it pays for itself many times over
Savings figure from Energy Saving Trust. Actual savings depend on your home, heating system, and energy tariff.
ECO4 — Free Loft Insulation (Ends December 2026)
ECO4 is the main route for free loft insulation in the UK. It's funded by energy suppliers and covers homes in England, Scotland, and Wales.
Who qualifies
- You receive a qualifying benefit — Universal Credit, Pension Credit, Income Support, Income-based JSA or ESA, Child Tax Credit (income under £18,500), or Housing Benefit
- Or your council refers you under ECO4 LA Flex — typically household income below £31,000, or a health condition worsened by cold housing
- Your home has an EPC rating of D, E, F, or G
- Your current loft insulation is below the recommended 270mm
⚠️ ECO4 closes 31 December 2026 with no successor scheme announced. If you're eligible, apply now — demand for installations increases as the deadline approaches.
Warm Homes: Local Grant — Free Loft Insulation
The Warm Homes: Local Grant can also fund loft insulation at no cost. It's delivered through your local council in England — councils like Hull (which secured £3.4M in funding) are actively delivering installations.
Who qualifies
- Household income of £36,000 or less — or you live in an eligible postcode area, or someone receives qualifying benefits
- EPC rating of D, E, F, or G
- Privately owned or privately rented property in England

What to Expect During Installation
Loft insulation is one of the least disruptive home improvements:
- Assessment — An assessor checks your loft space, measures existing insulation, and confirms the work needed (30–60 minutes).
- Installation — Mineral wool rolls are laid between and over the joists to reach 270mm. A standard loft takes 1–2 hours.
- Access hatch — The installer insulates the loft hatch too, which is a common source of heat loss.
- Updated EPC — After installation, you can get a new EPC certificate showing the improvement.
You don't need to clear your loft completely, but moving items away from the hatch area helps. The installer works from the hatch — there's usually no need for scaffolding.
When Loft Insulation Isn't Suitable
Loft insulation isn't right for every home. You may not be suitable if:
- Flat roof — Different insulation methods are needed for flat roofs
- Converted loft — If your loft is a living space, you need rafter insulation instead
- Damp or roof damage — Any leaks or damp issues must be fixed before insulating
- Already at 270mm — If your loft insulation is already at the recommended depth, you won't qualify for more
If loft insulation isn't suitable, you may still qualify for other measures like cavity wall insulation, solid wall insulation, or heating upgrades through the same schemes.
⏰ ECO4 closes December 2026 — some suppliers have already met their targets

Frequently Asked Questions
Can I get free loft insulation if I'm not on benefits?
Yes. The Warm Homes Local Grant accepts households with income below £36,000, regardless of benefits. Your council can also refer you under ECO4 LA Flex if you're on a low income or have a health vulnerability.
My loft already has some insulation. Can I still get more?
Yes, if it's below 270mm. Many homes built before the 2000s have 100mm or less. A top-up to 270mm is eligible under both ECO4 and the Warm Homes Local Grant.
I use my loft for storage. Is that a problem?
Insulation can be installed around stored items, though the installer may need items moved from certain areas. If you use your loft as a living space, rafter insulation is needed instead — which is also available through grants.
Is loft insulation safe?
Yes. Modern mineral wool insulation is non-combustible, doesn't rot, and doesn't attract pests. It's the most common type installed under government schemes.
How long does loft insulation last?
Mineral wool loft insulation lasts 40+ years with no maintenance needed. It doesn't degrade over time.
Will loft insulation make my home warmer in summer too?
Yes. Loft insulation reduces heat transfer in both directions — it keeps warmth in during winter and reduces heat entering through the roof in summer.
