Home Energy Scotland Grant and Loan 2026: How to Claim Up to £15,000 in Grants

The Home Energy Scotland grant is one of the most generous energy efficiency funding programmes available anywhere in the UK. Backed by the Scottish Government, it offers homeowners grants of up to £7,500 for insulation (75% of the cost) and a further £7,500 for clean heating systems such as heat pumps, with optional interest-free loans on top. If you live in Scotland and your property needs upgrading, this guide explains exactly how the scheme works, what you can claim, and how to apply.

How Much Can You Get from Home Energy Scotland?

Home Energy Scotland offers homeowners grants of up to £15,000 in total: up to £7,500 towards a clean heating system such as a heat pump, and up to £7,500 (75% of the cost) towards insulation and other energy efficiency measures, with optional interest-free loans on top. Rural and island homes get an extra £1,500 on each grant, up to £18,000 in grants. Standard solar PV panels are not funded.

To apply, call Home Energy Scotland free on 0808 808 2282. An adviser will assess your home and recommend suitable measures before helping you complete the application. The interest-free loan is repaid over up to 10 years, and there are no arrangement fees. If you also meet the criteria for Warmer Homes Scotland, you may be referred for fully funded improvements instead.

What Is the Home Energy Scotland Grant?

Home Energy Scotland (HES) is the Scottish Government’s national energy advice service. It provides free, impartial guidance on reducing energy bills and cutting carbon emissions, but its most valuable offering is direct financial support through grants and interest-free loans for home energy improvements.

The programme is delivered by Energy Saving Trust on behalf of the Scottish Government and is available to homeowners across Scotland for the home they live in, which must be their only or main residence and an existing property. Unlike many UK-wide schemes, HES funding is not means-tested for the basic grant, meaning homeowners at any income level can apply.

The scheme covers two main categories of improvement: insulation measures and renewable heating systems. Each category has its own grant cap, and you can claim from both simultaneously, giving a combined maximum of £15,000 in grant funding.

Home Energy Scotland Grant Amounts for 2026

The grant amounts depend on the type of improvement and whether you qualify for any rural or island top-ups. Here is a breakdown of the current funding levels.

Homeowners in remote rural areas and island communities can access an additional £1,500 on each grant, heating and energy efficiency, recognising the higher installation costs in these locations. This means a rural household could receive up to £18,000 in total grant funding.

Interest-Free Loans to Bridge the Gap

Where the grant does not cover the full cost, the Home Energy Scotland loan provides additional support. Interest-free loans of up to £7,500 for a heating system and, for energy efficiency, up to each improvement’s loan limit (for example £2,500 for solid wall insulation or £8,000 for replacing single glazing) are available, repayable over up to 10 years with no interest charged.

You can combine the grant and loan for the same project. For example, if an air source heat pump installation costs £12,000, you could receive a £7,500 grant and a £4,500 interest-free loan, meaning zero upfront cost and monthly repayments of around £37.50 over ten years.

The loan is subject to a credit check, but the criteria are more relaxed than a typical personal loan. There are no arrangement fees or early repayment penalties.

Who Is Eligible for the Home Energy Scotland Grant?

Eligibility for the HES grant is broader than most UK energy schemes. The main requirements are as follows.

• You must own the home in Scotland that you live in
• It must be your only or main private residence
• The home must have been built and occupied before the application date
• You must not have already received an HES grant for the same measure on the same property
• The work must be carried out by a Home Energy Scotland approved installer
• For heat pump grants, the installer must be MCS-certified

There is no income threshold for the standard grant, which sets it apart from schemes like ECO4 and the Warm Homes Local Grant in England. However, if you are on certain benefits, you may qualify for additional support through the Warmer Homes Scotland programme instead.

How to Apply for the Home Energy Scotland Grant

The application process is straightforward but must follow a specific sequence. Here is a step-by-step guide.

Step 1: Call Home Energy Scotland

Phone 0808 808 2282 (freephone, Monday to Friday, 8am to 8pm, Saturday 9am to 5pm). An adviser will discuss your property, current heating system, and which improvements would benefit you most. You can also request a callback through the Home Energy Scotland website.

Step 2: Get a Home Energy Assessment

HES may arrange a free home energy assessment where an assessor visits your property, checks insulation levels, inspects the heating system, and identifies eligible improvements. This step is essential for determining exactly which measures you can claim for.

Step 3: Receive Your Grant Offer

Based on the assessment, HES will issue a formal grant offer letter detailing the approved measures and funding amounts. Funding agreements are valid for nine months, so plan the work to finish within that window.

Step 4: Choose an Approved Installer

You must use an installer from the HES approved list. For heat pumps, this means an MCS-certified installer. For insulation, the installer must hold appropriate PAS 2030 accreditation and be TrustMark registered.

Step 5: Complete the Work and Claim

After installation, submit your completion paperwork and invoices to HES. The grant is paid directly to you, usually within four to six weeks of a successful claim.

Which Measures Offer the Best Value?

Not every improvement delivers the same return. Here is how the most popular measures compare when funded through the Home Energy Scotland grant (loft and cavity wall costs are Energy Saving Trust figures).

Insulation measures typically deliver the best return: the grant pays 75% of the cost, up to each measure’s limit. A semi-detached household insulating an empty loft and cavity walls could save about £390 a year (Energy Saving Trust), paying about £890 after the grants, or less with the optional loans.

Combining the Home Energy Scotland Grant with Other Schemes

The Boiler Upgrade Scheme only covers England and Wales, so it isn’t available for homes in Scotland; the HES grant is the heat pump grant here. You can combine HES funding with the following.

• Warm Home Discount – The £150 energy bill rebate is separate and can be claimed alongside HES grants
• Warmer Homes Scotland – If you qualify on benefits, you may receive fully funded improvements through this route instead
• Local authority grants – Some Scottish councils offer additional funding that can be stacked with HES
• SEG payments – If you install solar panels alongside other measures, Smart Export Guarantee payments provide ongoing income

If you are unsure which combination of schemes works best for your property, you can request a free quote through Home Energy Quotes — up to three approved installers who cover your area may contact you, with no charge and no obligation.

Common Mistakes to Avoid

Thousands of Scottish homeowners miss out on HES funding each year due to avoidable errors. Watch out for these common pitfalls.

• Starting work before receiving the grant offer – Any work completed before approval will not be funded
• Using a non-approved installer – The grant will be rejected if the installer is not on the HES approved list
• Letting the offer expire – Funding agreements last nine months, and delays in scheduling installers can eat into this window
• Not claiming both categories – Many homeowners apply for insulation but forget they can also claim for a heat pump or vice versa
• Assuming you do not qualify – There is no income threshold for the standard grant, so even higher earners are eligible

Frequently Asked Questions

Can private landlords apply for the Home Energy Scotland grant?

No. The Home Energy Scotland Grant and Loan is for homeowners improving the home they live in, which must be their only or main residence. Landlords should ask Home Energy Scotland about the support available for rented homes.

How long does the Home Energy Scotland application take?

From initial call to grant offer typically takes four to eight weeks, depending on whether a home assessment is needed and current demand. The installation itself then needs to be completed within the nine-month funding agreement. In total, expect the full process from first call to completed work to take three to six months.

Do I need to pay anything upfront?

For insulation measures where the grant covers the full cost, you may pay nothing upfront. For higher-cost measures like heat pumps, you may need to pay the installer the difference between the total cost and the grant amount. The interest-free loan can cover this gap if you prefer not to pay out of pocket.

Is the Home Energy Scotland grant taxable?

No. The HES grant is not treated as taxable income for homeowners. Landlords should consult their accountant, as the tax treatment may differ depending on whether the improvements are classified as capital expenditure or repairs.

Can I combine the HES grant with the Boiler Upgrade Scheme?

No, because the Boiler Upgrade Scheme only covers England and Wales. For a home in Scotland, the HES grant is the equivalent: up to £7,500 towards a heat pump, or £9,000 for rural and island homes, with an optional interest-free loan of up to £7,500 on top.
