Home Energy Scotland Grants in Perth

Home Energy Scotland is a Scottish Government programme that offers grants and interest-free loans for energy-efficient heating and insulation. It’s Scotland-specific, and it’s the main funding route for Perth homeowners looking to upgrade their heating or improve their insulation.

The funding is property-based, not means-tested. There’s no income threshold and no benefits requirement. If the property qualifies, you qualify. Subject to eligibility check.

NK Heating Solutions is an MCS and TrustMark registered installer, which are the accreditations required for HES-funded work. We’ll support you through the application and carry out the installation.

Grants range from £1,500 to £7,500 depending on the measure, with interest-free loans available alongside, and rural and island properties can often claim more on top. The full breakdown, including the rural uplift, is below.

What Home Energy Scotland Funds

Here’s exactly what Home Energy Scotland covers, and how much you could receive. All figures are subject to eligibility check. Figures verified August 2026.

Air source heat pumps – grant of £7,500, with an interest-free loan of up to £7,500. The heat pump must provide 100% of your heating and hot water. Hybrid heat pumps are not eligible. If you’re replacing an existing heat pump, the grant doesn’t apply, but the interest-free loan is still available.

High heat retention storage heaters – grant of £2,500, with a loan of up to £5,500. These are available where a heat pump isn’t suitable for the property. An MCS-certified installer confirms this, or an EPC showing you live in a flat.

Solid wall insulation (internal or external) – grant of £7,500, with a loan of up to £2,500.

Flat roof and room-in-roof insulation – grant of £3,000, with a loan of up to £1,000.

Loft, cavity and underfloor insulation – grant of £1,500, with a loan of up to £500.

Energy-efficiency grants (insulation measures) cover up to 75% of the combined cost, capped at £7,500. An EPC is required for all energy-efficiency measures. It’s not required for heat pumps.

Rural and island uplift: if your property is in a rural area, an additional £1,500 applies to both heating and energy-efficiency grants. Rural households can claim up to £18,000 in total grant funding.

Funding is first-come, first-served and subject to availability. Agreements run for nine months. Interest-free loans carry a 1.5% admin fee, capped at £150.

A note on boiler grants. If you’ve searched for a boiler grant, here’s the honest answer. Home Energy Scotland does not fund replacing a gas boiler with another gas boiler. The grant covers switching to an air source heat pump, and at £7,500 it covers a significant portion of the cost. If your gas boiler needs replacing, a like-for-like swap is a private purchase, but switching to a heat pump with HES funding is worth looking at.

How to Check If You Qualify and How to Apply

If the EPC recommends insulation or a heating upgrade, that’s a strong signal you qualify. An EPC is required for insulation measures. It’s not required for heat pumps. The property can be owner-occupied or privately rented with the landlord’s agreement.

Here’s what the application process looks like:

Get in touch with Home Energy Scotland or NK Heating Solutions to discuss what measures suit your property. Get an EPC if you don’t already have one (needed for insulation measures). Apply to Home Energy Scotland. You manage the application yourself. NK Heating Solutions will support you through it, but we don’t manage HES applications on your behalf. HES approves the funding and confirms your grant and loan amounts. NK Heating Solutions carries out the work as the accredited installer. On completion, a Qualitymark guarantee is issued covering 25-year system and 2-year workmanship.

What NK Heating Solutions does at the support stage: we help you understand what you’re eligible for, provide the survey and quote that feeds the application, and explain what documentation Home Energy Scotland needs. We stop short of managing the application itself.

The timeline varies. HES agreements allow nine months. NK Heating Solutions can give you a realistic picture after the initial survey. Funding is subject to availability, so starting sooner is better.

FAQs

Am I eligible for the Home Energy Scotland grant?

Eligibility is property-based, not means-tested. There’s no income or benefits threshold. It’s driven by your property’s current Energy Performance Certificate and what improvements it recommends. If the EPC recommends insulation or a heating upgrade, that’s a strong signal you qualify. The property can be owner-occupied or privately rented with the landlord’s agreement. Subject to eligibility check.

How much grant funding can I get from Home Energy Scotland?

It depends on the measure. Air source heat pumps: £7,500. Solid wall insulation (internal or external): £7,500. Flat roof and room-in-roof insulation: £3,000. Loft, cavity and underfloor insulation: £1,500. High heat retention storage heaters: £2,500. Interest-free loans are available alongside each grant. If your property is in a rural area, a £1,500 uplift applies. All figures are subject to eligibility check.

Can I get a grant for a new boiler?

Home Energy Scotland does not fund replacing a gas boiler with another gas boiler. The grant covers switching to an air source heat pump, and at £7,500 it’s a substantial contribution. If your home is on gas and the boiler needs replacing, a like-for-like gas boiler is a private purchase. But switching to a heat pump with HES funding may cover a significant portion of the cost. That’s the honest answer.

Do I have to pay anything myself?

Grants cover a significant portion of the cost, but rarely 100%. Energy-efficiency grants cover up to 75% of the combined cost, capped at £7,500. Interest-free loans are available to bridge the gap. The out-of-pocket amount depends on the measure, the property and the quote. NK Heating Solutions can give you a realistic picture after the survey. Loans carry a 1.5% admin fee, capped at £150.

Does NK Heating Solutions handle the application for me?

For Home Energy Scotland: no. You manage the HES application yourself. NK Heating Solutions supports you through it by providing the survey, the quote and guidance on what documentation is needed. For Warmer Homes Scotland, Warmworks manages that scheme’s applications as the appointed delivery partner. Get in touch with NK Heating Solutions to talk through your options either way.

What accreditations does NK Heating Solutions hold for grant-funded work?

MCS (held for 12 years), TrustMark, PAS2030 (held since 2021), Qualitymark, NICEIC, BPEC and Gas Safe (registered for 30 years). These aren’t optional. MCS is required for HES-funded heat pump installations. TrustMark is required for HES-funded insulation work. PAS2030 is the overarching standard for all government-funded energy efficiency work. NK Heating Solutions holds every accreditation the funding requires.

Is my work guaranteed after the grant?

Yes. All government-funded work carried out by NK Heating Solutions comes with a Qualitymark insurance-backed guarantee. That’s 25-year system cover and 2-year workmanship cover. NK Heating Solutions is the installer and the guarantee issuer. The guarantee is insurance-backed.
