Home Energy Scotland Grant & Loan 2026: Up to £18,000

Working out how to pay for a heat pump, new insulation, or solar panels is where most home upgrades stall. The kit is expensive, the savings take years to arrive, and borrowing at normal rates eats into the benefit. This is where the Home Energy Scotland Grant and Loan comes in – a Scottish Government scheme that hands you free grant money and lets you borrow the rest interest-free.

Here’s the honest version of how it works in 2026, what you can actually get, and the traps that catch people out. You could pick up up to £7,500 in free grant funding for a heat pump, plus up to £7,500 more as an interest-free loan on top. For energy efficiency work like insulation, grants cover up to 75% of the cost. And if you live somewhere rural, there’s an extra £1,500 uplift that pushes the total as high as £18,000.

This guide covers every measure the scheme funds, exactly who qualifies, how repayment works, and the step-by-step application. It also flags the things the official pages bury – like the glazing rule that trips up a lot of homeowners, the change that means standard solar panels no longer qualify, and what happens if the money runs out before your application lands.

What the scheme actually is (and who runs it)

The Home Energy Scotland Grant and Loan is a pot of Scottish Government money designed to get homes off fossil fuel heating and better insulated. It launched in 2022 and has funded thousands of installations since.

It’s delivered by Home Energy Scotland, a free advice service run by Energy Saving Trust on the government’s behalf. Energy Saving Trust is authorised and regulated by the Financial Conduct Authority, which matters because they’re handling the loan side. The scheme splits into two types of funding that work together:

• Grants – money you never pay back, aimed mainly at clean heating and insulation.
• Interest-free loans – money you do pay back, but at 0% interest, to cover the rest of the cost.

You can take a grant, a loan, or a combination. For most people the smart move is to take every pound of grant you’re entitled to first, then borrow the shortfall interest-free.

Who qualifies

The eligibility rules are refreshingly simple, and this is where the scheme beats most funding out there. You qualify if the property is an existing home in Scotland (not a new build), you are the homeowner who lives there, and it is your only or primary private residence.

That’s it. You do not need to be on any benefits. There’s no income cap for the core scheme. If you own your home and live in it, you’re through the door.

What “primary residence” really means

This phrase does a lot of quiet work, so let’s be clear about it. Your primary residence is the home you actually live in most of the time – your main address. That rules out three groups: holiday home owners (a second property for weekends doesn’t count), landlords (if you rent it out and don’t live in it), and second-home owners generally (the scheme funds one home per person, the one you live in). If you own a home you don’t live in, this particular scheme isn’t for you – landlords should look at the separate Private Rented Sector Landlord Loan instead.

What it covers: grants vs loans by measure

This is the heart of the scheme, and the funding split changes depending on what you’re installing. Some measures come with generous grants. Others are loan-only. Here’s the full breakdown.

The headline deal here is the heat pump: £7,500 grant plus £7,500 loan, covering up to £15,000. One important catch – only heat pumps that provide 100% of your heating and hot water qualify. Hybrid heat pumps are not funded at all. And note that replacement heat pumps get the loan but not the grant: if you already have one and want a new one, you can borrow up to £7,500 interest-free, but the £7,500 grant is off the table.

For insulation, the grant covers up to 75% of the combined cost of your measures, up to the caps below, with the rest available as a loan.

The glazing trap: the rule that catches people out

This one deserves its own section, because a lot of homeowners get it wrong. You might see “up to £8,000 for glazing” and assume you can swap out your tired old double glazing for new units on an interest-free loan. You can’t.

So if your home already has double glazing that’s failed or misted up, this scheme will not help you replace it. The money is strictly for homes still on single glazing that want to move up. There’s one small mercy: if your home needs double or triple glazing but you can only afford secondary glazing, the scheme will accept a secondary glazing application – you just have to include a cover letter explaining the situation.

The rural uplift: up to £18,000

If you live somewhere remote, the scheme recognises that installers cost more to get to you and gives you extra. A £1,500 uplift is added to both the heating and the energy efficiency grants for homes in remote rural areas, island communities, and off-gas accessible rural areas.

What the scheme does NOT cover

Knowing the exclusions saves you wasted time and disappointment. The scheme will not fund:

• Existing double, triple or secondary glazing replacement – only single-glazing upgrades qualify.
• Standalone solar PV panels or battery storage – only within a full heating package, never on their own.
• Spray foam insulation – not funded under any circumstances.
• Hybrid heat pumps – only full systems providing 100% of heating and hot water.
• Second homes and holiday homes – primary residence only.
• Rental properties where you’re the non-resident landlord.
• New build homes – the property must be existing.
• Non-automated, non-pellet stoves and room heaters.
• Work already started or completed – you cannot get funding retrospectively.

That last point is critical. Do not start any installation before you have a written funding offer. Begin work early and you lose the funding entirely.

Grants vs loans explained

Let’s keep this simple, because the two work very differently. A grant is free money – the government pays it toward your installation and you never pay it back, so you want to claim as much as you’re entitled to. A loan is money you borrow and repay, but here it’s at 0% interest, which makes it far cheaper than a normal bank loan or credit card. Think of it as spreading the cost with no penalty for doing so.

For a heat pump, the two combine neatly. The £7,500 grant knocks the price down, and the £7,500 loan lets you spread the remaining cost over years without paying a penny in interest. The only cost of borrowing is the small admin fee, which we’ll cover next.

Repayment terms and the admin fee

If you take any loan funding, the scheme runs standard checks and charges one modest fee. You pay a one-off admin fee of 1.5% of the total loan value, capped at £150 per application. That’s the only charge on the loan – there’s no interest on top.

• Borrow £5,000 → admin fee is £75.
• Borrow £10,000 → admin fee is £150 (the cap).
• Borrow £15,000 → admin fee is still £150 (capped).

So on a £10,000 interest-free loan, your total cost of borrowing is £150 and nothing else. Compare that to a typical bank loan at 7% over 10 years, where you’d pay several thousand pounds in interest, and the value is obvious.

Repayments begin after you receive your first payment from the scheme, including any deposit drawdown. So the clock starts once money lands, not when you apply.

Credit checks for loan applicants

Because the loan is real borrowing, the scheme carries out affordability and credit checks before approving loan funding, plus identity and anti-fraud checks before releasing any money. What this means for you: if your credit is poor, the loan portion may be declined, even though the grant side doesn’t need a credit check. If you’re worried about this, you can still apply for grant-only funding and cover the rest yourself. Don’t assume the loan is automatic – it’s a proper lending decision.

Step-by-step: how to apply

The process runs through Home Energy Scotland from start to finish. Here’s the full journey.

1. Call Home Energy Scotland. Phone the free advice line on 0808 808 2282 (Monday to Friday 8am to 8pm, Saturday 9am to 5pm). Prefer email? Use the contact form on their website and you’ll hear back within 10 working days.
2. Get advice and check your options. An advisor works out what you’re eligible for. For energy efficiency measures like insulation, you’ll need a valid EPC, and the improvement must appear in that EPC’s recommendations. For clean heating and renewables like heat pumps, you do not need an EPC.
3. Application referral. After your call, you’ll get an email with a link to start your application, usually within two working days.
4. Complete the online application. Register on the portal, agree to the terms, confirm you won’t start work until you have a written offer, and upload your EPC (for efficiency measures) and itemised installer quotes. Progress saves as you go.
5. Processing. The team aims to process applications within 10 working days. Missing documents slow this down – they’ll send up to three reminders, and if you don’t respond, the application expires.
6. Funding offer and installation. If approved, you get a written funding offer. You must review and sign the funding agreement electronically within 14 days. Only then can work start – and once signed, you have 9 months to complete everything and submit your final claim.

Deposit drawdown: get up to 60% upfront for renewables

Here’s a feature many homeowners miss. For renewable systems – heat pumps, solar thermal and the like – you don’t have to wait until the job’s done to see money.

How to claim your funding after installation

You claim per measure as each installation finishes, so individual installers can be paid without waiting for the whole project to wrap up. To claim, submit through the portal with the invoice for the completed work, a post-installation EPC (which must not still recommend the measure you just installed), your payment account details, and an MCS certificate for renewable installations.

Claims are processed within 10 working days of all documents being received, and payment goes out by BACS, taking three to five working days. One responsibility sits with you: Energy Saving Trust pays you, not the installer, so it’s your job to pay your installer once the funding lands – and to submit proof of payment (a bank statement or receipt) within 10 working days.

Choosing an installer

The scheme has firm rules on who can do the work, and they vary by measure. Get this wrong and your funding falls through.

• For insulation (solid wall, underfloor, flat roof or room-in-roof): your installer must be registered with TrustMark for those measures. Find registered installers on the TrustMark website.
• For heat pumps and renewables: both your installer and the product must be certified under the Microgeneration Certification Scheme (MCS) for the system being installed. Micro-hydro is the one exception, assessed case by case.
• Whatever you install: get at least three quotes, check the installer is accredited with a relevant trade body, and ask what guarantees and warranties they provide on the work and the products.

You can search for MCS-certified installers on Energy Saving Trust’s Renewables Installer Finder, which also carries customer reviews.

How to combine it with other schemes

The Home Energy Scotland funding doesn’t have to stand alone. Two combinations are worth knowing about.

Solar and the Smart Export Guarantee

If you’re adding solar as an eligible PV-T system, or you already have panels, the Smart Export Guarantee (SEG) pays you for the electricity you export to the grid. Energy suppliers set their own SEG rates, so you can shop around for the best one. The smart play is to fund eligible kit through the interest-free loan, then earn SEG income on top from the power you don’t use yourself. Just check the eligibility rules for both, because being eligible for one doesn’t guarantee eligibility for the other.

Warmer Homes Scotland

If you’re on a low income or receiving certain benefits, you may qualify for Warmer Homes Scotland, a separate government scheme offering free or heavily subsidised improvements. It’s worth running the self-assessment tool before you commit to the Grant and Loan, in case you’re entitled to more support. The Home Energy Scotland advisor can point you toward whichever route fits best – being eligible for one scheme doesn’t mean you’re eligible for another.

Mistakes to avoid

• Starting work before you get a written offer. The big one. Begin early and you lose all funding – it can never be granted retrospectively.
• Assuming the glazing loan covers existing double glazing. It only covers single-glazing upgrades, and it’s loan-only.
• Applying for a hybrid heat pump. Only full systems that provide 100% of heating and hot water qualify.
• Forgetting the EPC recommendation. For insulation, the measure must be listed in your EPC’s recommendations or it won’t be funded.
• Missing the 14-day signing window on your funding offer.
• Letting documents lapse. Ignore the reminders and your application expires.
• Assuming funding is guaranteed. It runs first-come, first-served and can run out.

What happens if the funding runs out?

This is the risk the official pages state plainly but few homeowners register: funding is allocated on a first-come, first-served basis and is subject to availability, or until the end of the financial year, whichever comes first.

The 9-month deadline: don’t get caught out

Once you sign your funding agreement, the clock starts. You have 9 months to complete all installations and submit your final claim, and your funding offer expires at the end of that period. Nine months sounds generous, but heat pump and insulation installers can have long waiting lists, especially in peak season. If your installer can’t start for three months, you’ve already burned a third of your window.

To stay safe, line up your installer before you apply so work can begin as soon as your offer lands, book the job in early rather than leaving it to the back end of the 9 months, and track your deadline. If you’re heading toward it with work unfinished, contact the Services Delivery Team on 0808 108 9414 as early as possible – leaving it late risks losing funding you’ve already been offered.
