Loft Conversion Grants UK: What's Actually Funded

Last updated: 2 July 2026

Straight talk: there's no general government grant to turn your loft into a room. But loft insulation, disabled adaptations and energy-efficiency measures are funded — here's exactly what you can and can't claim in 2026.

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. If you searched for a loft conversion grant but really want cheaper, warmer loft insulation, jump to our loft insulation grant guide.

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.

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.

Loft Conversion Grants — Common Questions

No. There is no general government grant that pays for turning a loft into a habitable room. Energy and fuel-poverty schemes fund efficiency and disability need, not living-space improvements that add value. However, loft insulation is often funded (sometimes free), and a Disabled Facilities Grant can fund a loft conversion in the specific case where it's needed to meet a disabled person's assessed needs.
Not for a standard conversion. The main council route relevant here is the Disabled Facilities Grant, which can fund a loft or upper-floor conversion only where it is necessary and appropriate to meet a disabled resident's needs — for example an accessible bedroom or bathroom where no ground-floor option exists. Councils also administer energy-efficiency schemes such as the Warm Homes: Local Grant, which fund insulation and heating, not room conversions.
Yes — and this is what most people searching for loft grants actually need. Loft insulation is funded, and often completely free, through ECO4 for households on a qualifying benefit and through the Warm Homes: Local Grant. It cuts heat loss and lowers bills. See our loft insulation grant guide and use the eligibility checker to see what you qualify for.
The maximum is up to £30,000 in England, £36,000 in Wales and £25,000 in Northern Ireland. It's means-tested for adults (income and savings over £6,000 are considered) but not for disabled children under 18. It funds adaptations that let a disabled person live safely at home — ramps, stairlifts, accessible bathrooms, suitable heating, and, where genuinely needed, an extension or upper-floor conversion.
Many loft conversions on houses fall under permitted development and don't need a full planning application, subject to volume limits and rules on dormers and roof height. Flats and maisonettes usually need full planning permission. Separately, every habitable loft conversion needs building-regulations sign-off covering structure, fire escape, insulation and staircase safety. These are legal approvals, not grants.
The conversion work itself is generally charged at standard-rate VAT. However, qualifying energy-saving materials such as insulation installed in residential homes currently benefit from a 0% VAT rate (running until 31 March 2027). So the insulation element of your project can be cheaper. Ask your installer to itemise energy-saving materials separately on the quote.
