There is no general government grant for a loft conversion in the UK. Turning a loft into a habitable bedroom, office or bathroom is classed as a home improvement that adds value, so it isn't covered by energy or fuel-poverty grant schemes. What is funded is different: free loft insulation (through schemes like ECO4), Disabled Facilities Grants of up to £30,000 in England where a loft room is genuinely needed to meet a disabled person's assessed needs, and energy-efficiency measures such as insulation and low-carbon heating.

The Honest Answer: Is There a Grant for a Loft Conversion?
Let's be clear, because a lot of pages online are not: there is no dedicated UK grant that pays for a standard loft conversion. If you want to convert your loft into a bedroom, home office, or extra bathroom, you will normally be funding that yourself.
The reason is simple. Government grants in this space exist to tackle fuel poverty, poor energy efficiency, and disability need — not to add living space and value to a home. A loft conversion typically increases a property's value, so it falls outside what schemes like ECO4 or the Warm Homes: Local Grant are designed to pay for.
That said, several parts of what people call a "loft project" genuinely are fundable. Below is exactly what you can and can't get help with.
What You Can Actually Get Funding For
| Measure | Funded? | Route |
|---|---|---|
| Turning a loft into a habitable room | No general grant | Self-funded / home improvement loan |
| Loft (roof) insulation | Yes — often free | ECO4, Warm Homes: Local Grant |
| Home adaptations for a disabled person | Yes — up to £30,000 (England) | Disabled Facilities Grant |
| Low-carbon heating & energy efficiency | Yes | ECO4, Boiler Upgrade Scheme |
| Energy-saving materials (e.g. insulation) | 0% VAT until 31 March 2027 | VAT relief |
1. Loft Insulation — Often Completely Free
This is the big one, and it's almost certainly what many people searching for "loft grants" actually need. Loft insulation (insulating the roof space to stop heat escaping) is funded — and often free — through schemes such as ECO4 for households on a qualifying benefit, and the Warm Homes: Local Grant. If you're insulating an existing loft — not converting it — this is your route. Read our full loft insulation grant guide.
2. Disabled Facilities Grant — Up to £30,000
The Disabled Facilities Grant (DFG), run by your local council, is the one route where a loft or upper-floor conversion can sometimes be funded — but only where it is necessary and appropriate to meet a disabled person's assessed needs (for example, creating an accessible bedroom or bathroom where no suitable ground-floor option exists). It is not a grant for adding space for its own sake. The maximums are:
- England: up to £30,000
- Wales: up to £36,000
- Northern Ireland: up to £25,000
The DFG is means-tested for adults (based on income and savings over £6,000), but not means-tested for disabled children under 18. It can also fund a heating system suited to the person's needs. If this applies to your household, our energy grants for disabled people guide has more detail, and you should speak to your council's home adaptations or occupational therapy team.
3. Energy-Efficiency Measures Within a Project
If your wider works include improving efficiency — better insulation, a low-carbon heating system — those specific measures may be fundable even when the conversion itself isn't. ECO4 can fund insulation and heating for eligible households, and the Boiler Upgrade Scheme offers £7,500 toward a heat pump. These are separate from the conversion and judged on their own eligibility rules.
4. VAT Relief on Energy-Saving Materials
You won't get the conversion VAT-free, but the government currently applies a 0% VAT rate to qualifying energy-saving materials such as insulation installed in residential homes (this reduced rate runs until 31 March 2027). So the insulation element of a loft project can be cheaper. See our VAT relief guide for what qualifies.
Watch out: Be sceptical of any company advertising a "loft conversion grant" that asks for an upfront fee. There is no national grant that pays for a standard loft conversion. Legitimate energy-grant assessments (like ECO4) are free — you should never pay upfront to "unlock" one.
Loft Conversion vs Loft Insulation — Don't Confuse the Two
This is the heart of the confusion, so it's worth spelling out:
- Loft conversion = structural work to turn the roof space into a usable, habitable room (stairs, floor strengthening, windows, insulation, building-regulations sign-off). No general grant.
- Loft insulation = laying or topping up insulation in the roof space to cut heat loss and bills. Often free through energy grants.
If your real goal is a warmer home and lower bills, you want loft insulation, and there's very likely funding for it. If you genuinely want the extra room, read on for how conversions are actually paid for.
Why Loft Conversions Aren't Grant-Funded
Three practical reasons a standard loft conversion sits outside grant schemes:
- It adds value. Energy and fuel-poverty grants target hardship and efficiency, not improvements that increase a property's worth.
- It's discretionary. Unlike a broken boiler or a cold, damp home, extra living space is a choice rather than a health or affordability necessity.
- Planning and building regs, not grants, govern it. Most house loft conversions fall under permitted development, but every habitable conversion needs building-regulations sign-off. Flats and maisonettes usually need full planning permission. These are approvals to build safely and legally — not sources of funding.
How People Actually Fund a Loft Conversion
Since grants aren't available for the conversion itself, the realistic options are:
- Savings or staged payments to the builder
- A further advance on your mortgage, or remortgaging to release equity
- A secured or unsecured home-improvement loan
Whatever you choose, make sure your quotes separate out the insulation and energy-efficiency elements — those may qualify for the 0% VAT rate or, in the right circumstances, a separate energy grant, which can shave real money off the total.
