Heat Pump Grants in Scotland 2026 — Home Energy Scotland

Scottish homeowners have access to some of the best heat pump funding in the UK. You can combine a £7,500 Boiler Upgrade Scheme grant with Home Energy Scotland's interest-free loan and cashback, potentially cutting the cost of a heat pump installation by £10,000 or more. Here's how each funding stream works in 2026, what you're actually eligible for, and how to apply without tripping up.

What Funding Is Available for Heat Pumps in Scotland in 2026?

Scotland has two main funding routes that can work together. The first is the UK-wide Boiler Upgrade Scheme, which gives you a £7,500 upfront grant. The second is the Home Energy Scotland (HES) interest-free loan, which offers up to £7,500 for a heat pump, plus an additional cashback element that you don't have to pay back.

The cashback amount through HES has historically been up to £7,500, though this is subject to available funding. You should check directly with Home Energy Scotland for the current cashback figure, as it can change during the financial year. The interest-free loan runs for up to 12 years, so repayments are manageable even on a modest household budget.

On top of these, some Scottish homeowners on lower incomes may qualify for Warmer Homes Scotland, which can cover the full cost of a heat pump installation. That scheme is means-tested and run by the Scottish Government through local delivery partners.

How Do Home Energy Scotland Loans and Cashback Actually Work?

Home Energy Scotland is funded by the Scottish Government and delivered by the Energy Saving Trust. It's not a grant in the traditional sense. It's an interest-free loan with a cashback bonus attached.

Here's how it breaks down for heat pumps in 2026:

• Loan amount: Up to £7,500, repaid interest-free over up to 12 years
• Cashback: Up to £7,500, paid after installation and not repayable
• Eligibility: You must own your home in Scotland and the property must be your main residence
• Installer requirement: Your installer must be MCS certified

The cashback is the bit that really matters. If you receive the full £7,500 cashback, you're effectively getting a grant. The loan portion just gives you a way to spread the remaining cost without paying any interest, which is a far better deal than any high-street personal loan.

To apply, you phone Home Energy Scotland on 0808 808 2282 or fill in the form on their website. They'll arrange a home energy assessment, talk you through your options, and process the loan application. The whole process typically takes a few weeks before you get approval.

Can You Stack the BUS Grant with Home Energy Scotland Funding?

Yes, and this is where Scotland genuinely has an advantage over England and Wales. The £7,500 BUS grant and the Home Energy Scotland loan and cashback are separate schemes run by different bodies, and they can be used on the same installation.

The Boiler Upgrade Scheme is administered by Ofgem on behalf of the UK Government, and it applies across England and Scotland. Your MCS certified installer applies for the BUS grant on your behalf, and the £7,500 is deducted directly from your invoice. You never handle that money yourself.

The Home Energy Scotland loan and cashback sit on top of this. So the maths can look very favourable indeed.

There's one thing to watch: the total grant and cashback funding you receive typically can't exceed the total cost of the installation. If your heat pump costs £12,000 and you've already got £7,500 from BUS, the HES cashback element may be capped so the combined support doesn't go above £12,000. Always confirm this with your HES adviser before committing.

What Would a Typical Scottish Installation Actually Cost After Grants?

Take a 1970s three-bedroom semi in Stirling. The homeowner gets three quotes for an 8.5kW air source heat pump, and the middle quote comes in at £13,500 including a new hot water cylinder and controls.

Here's how the funding stacks up:

That £2,500 can then be covered by the HES interest-free loan, repaid over 12 years at roughly £17 per month with zero interest. The homeowner has paid nothing upfront and owes just over £200 a year.

Compare that to the cost of a new gas boiler installation at around £3,000 to £4,500, and the heat pump is arguably the cheaper option once grants are applied. And it'll likely save money on energy bills too, particularly if you're on a heat pump electricity tariff.

The £7,500 Boiler Upgrade Scheme Grant — What Scottish Homeowners Need to Know

The BUS grant has been running since 2022 and was increased from £5,000 to £7,500 in late 2024. It's confirmed to continue through to at least March 2028, according to Ofgem's BUS guidance.

To qualify in Scotland, your property must:

• Have a valid Energy Performance Certificate (EPC)
• Be replacing a fossil fuel heating system (gas, oil, LPG, electric storage heaters, or coal)
• Not be a new build
• Use an MCS certified installer for the work

One common point of confusion: you don't apply for the BUS grant yourself. Your installer does it through the Ofgem portal. They'll need your EPC reference number and property details. Once approved, the £7,500 is knocked off your invoice before you pay.

If you're replacing an oil boiler in a rural Scottish property, you're almost certainly eligible. Oil prices have been volatile, and plenty of Scottish homeowners in the Highlands, Borders, and Dumfries and Galloway are making the switch for exactly this reason. You can find MCS certified installers in Glasgow and across Scotland through our directory.

Step-by-Step: How to Apply for Heat Pump Grants in Scotland

The process isn't complicated, but the order matters. Get it wrong and you could miss out on funding.

Step 1: Contact Home Energy Scotland. Call 0808 808 2282 or visit homeenergyscotland.org. They'll book a free home energy assessment and talk you through what you're likely to qualify for.

Step 2: Get your EPC. If you don't already have one, you'll need an Energy Performance Certificate. Your HES adviser can point you to an assessor, or you can find one on the Scottish EPC register.

Step 3: Get quotes from MCS certified installers. You need at least one quote, but getting two or three is wise. Every installer must be MCS certified to qualify for either the BUS grant or HES funding. Our guide on questions to ask before hiring will help you compare properly.

Step 4: Apply for the HES loan and cashback. Submit your application through Home Energy Scotland with your chosen quote. They'll process the loan and confirm the cashback amount.

Step 5: Your installer applies for the BUS grant. Once you've accepted a quote, your installer submits the BUS application through Ofgem. This must happen before installation begins.

Step 6: Installation and sign-off. After the heat pump is installed, your installer registers it with MCS and completes the BUS process. HES will release the cashback once they've confirmed everything is in order.

The whole process from first phone call to a working heat pump typically takes 8 to 16 weeks, depending on installer availability and how quickly the paperwork goes through.

"I'm Worried the Funding Will Run Out Before I Get Approved"

This is the single biggest concern we hear from Scottish homeowners, and it's a fair one. The BUS grant has a fixed budget each financial year, and Home Energy Scotland cashback depends on annual Scottish Government allocations.

Here's the reality in 2026: the BUS grant budget was significantly increased for this phase, and uptake across Scotland, while growing, hasn't exhausted the fund. But it's worth acting sooner rather than later. In previous years, some HES cashback funding was paused temporarily when demand spiked, so there's no guarantee it'll be available at the same level all year.

The best protection is to start the process now. Even if you're not ready to install for a few months, getting your HES application in early secures your place. And the BUS voucher, once issued, is valid for three months.

Don't let the fear of missing out paralyse you into doing nothing. The funding is there right now, and the application process is free. If it turns out you don't qualify, you've lost nothing but an hour of your time.

Frequently Asked Questions

Can I get a heat pump grant in Scotland if I have gas central heating?

Yes. The BUS grant and Home Energy Scotland funding both cover properties switching from gas boilers to heat pumps. You don't need to be off the gas grid to qualify. Your property just needs a valid EPC and the installation must be done by an MCS certified installer.

How much does a heat pump cost in Scotland after grants?

A typical air source heat pump installation in Scotland costs between £10,000 and £15,000 before grants. After the £7,500 BUS grant and up to £7,500 in HES cashback, your out-of-pocket cost could be as low as £0 to £3,000, depending on the total installation price and the cashback available at the time.

Do I apply for the BUS grant myself in Scotland?

No. Your MCS certified installer applies for the BUS grant through Ofgem on your behalf. You'll need to provide them with your EPC reference number and some property details, but the actual application is their responsibility. The £7,500 is then deducted from your final invoice.

Can I get Home Energy Scotland funding if I'm a private tenant?

The HES interest-free loan and cashback for heat pumps are generally available to homeowners only. If you're a private tenant, you'd need your landlord to apply. Landlords can access HES loans, but the cashback amounts may differ. Contact Home Energy Scotland directly to check what's available for your situation.

How long does the Home Energy Scotland loan application take?

Most applications are processed within two to four weeks, though it can vary depending on demand. The free home energy assessment needs to be completed first, and that booking can take a week or two. From first contact to loan approval, expect roughly three to six weeks in total.
