As of 2026, HES provides interest-free loans for energy efficiency and renewable heating measures, with a maximum combined loan amount of £38,500 per household (Home Energy Scotland, 2026). The loan covers a range of measures including solid wall insulation, cavity wall insulation, loft insulation, air source heat pumps, ground source heat pumps, solar PV, solar thermal, and battery storage. Loans are available to homeowners and private tenants in Scotland, though private tenants need landlord permission. The interest-free period is up to 10 years for most measures, with no early repayment penalties.
The specific loan amounts for each measure in 2026
Each eligible measure has a maximum loan amount set by Home Energy Scotland. These caps are intended to cover a significant portion of typical installation costs but may not cover the full project cost for larger properties or more complex installations.
- Air source heat pump: up to £9,000 (including installation) (Home Energy Scotland loan measure list, 2026).
- Ground source heat pump: up to £12,500 (including installation) (same page).
- Solar PV (panels and battery storage): up to £6,000 for solar PV, plus up to £4,000 for battery storage (Home Energy Scotland loan eligibility criteria).
- Solid wall insulation: up to £8,000 (internal or external) (Home Energy Scotland loan measure list).
- Loft insulation, cavity wall insulation, and other fabric measures: up to £1,500 per measure (same source).
The total loan cap for a single property is £38,500 across all eligible measures combined. This means you could, for example, take out a loan for a ground source heat pump and solid wall insulation simultaneously, provided the combined amount does not exceed the cap.
Interest rates and repayment terms — it is a 0% loan
Home Energy Scotland loans are interest-free at 0% APR for the full term (Home Energy Scotland loan terms page). The repayment term is typically 5 to 10 years depending on the measure. Heat pumps and solar PV have a 10-year term, while insulation measures have a 5-year term (Home Energy Scotland loan repayment schedule).
There are no fees for application, administration, or early repayment (same source). The loans are unsecured, meaning you do not need to use your home as collateral. Repayments start one month after the loan is paid out. Missed payments may incur standard debt collection charges but not interest.
Who qualifies for a Home Energy Scotland loan in 2026
You must own the property or be a private tenant with landlord permission (Home Energy Scotland eligibility criteria). The property must be in Scotland and be your permanent residence, not a holiday home or buy-to-let. There is no income or household earnings cap — the loan is not means-tested.
For some measures, such as heat pumps, the property must have an Energy Performance Certificate (EPC) rating of E, F, or G at the time of application. However, there is no EPC requirement for insulation-only loans (Home Energy Scotland loan eligibility page). You must also be able to pay any remaining cost above the loan cap yourself, as the loan covers up to 100% of eligible measure costs but total project cost may exceed the per-measure cap.
How the loan interacts with other grants — you can stack them
Home Energy Scotland loans can be combined with the Scottish Government’s Warmer Homes Scotland grant, which is for low-income households (Home Energy Scotland “Combining funding” page). However, you cannot receive a loan and a grant for the same measure from HES — you can use a loan for one measure and a grant for another on the same property.
The loan is not compatible with the UK Government’s ECO scheme (Energy Company Obligation) for the same measure, but you can use ECO for one measure and the HES loan for another (DESNZ guidance on ECO and devolved schemes, 2026). Solar PV and battery storage loans can be stacked with the Smart Export Guarantee (SEG) income from exporting electricity (Ofgem SEG guidance). The loan is not affected by the GB-wide Boiler Upgrade Scheme (BUS), which applies only to England and Wales.

What a Home Energy Scotland loan actually costs you over the full term
Because the loan is 0% interest, the total repayment equals the loan amount — there is no extra cost (HES loan terms). For example, a £9,000 air source heat pump loan over 10 years equals 120 monthly payments of £75, with total repaid of £9,000. A £1,500 loft insulation loan over 5 years equals 60 monthly payments of £25, with total repaid of £1,500.
The only additional costs are the measure installation costs above the loan cap, which you must pay directly to the installer. Payback time depends on energy savings. Based on Energy Saving Trust figures for a typical 3-bed semi-detached home, a heat pump might save £250 to £400 per year on heating bills (Energy Saving Trust, 2026). With a loan repaid in 10 years, net savings would start in year 11.

How to verify an installer and apply for the loan
All heat pump and solar PV installers must be MCS certified under the Microgeneration Certification Scheme (MCS register and Home Energy Scotland installer requirements). Insulation installers must be registered with TrustMark and have relevant insulation certification, such as NICEIC for solid wall insulation (TrustMark website and HES installer list). Gas boiler replacement is not covered by HES loans, so boiler installers need Gas Safe registration only if a boiler is involved — but boilers are not eligible for this loan.
The application process requires you to first get a quote from an MCS or TrustMark certified installer, then apply online via Home Energy Scotland. The loan is approved before work starts (Home Energy Scotland “How to apply” page). After installation, the installer must provide an MCS certificate or TrustMark certificate, and the loan is paid directly to you (the homeowner, not the installer) within 30 days of submission.
