Answer 6 questions to see which grants apply to your Scottish household — HES, Warmer Homes, ECO4 and more.
Scotland has devolved energy policy. Schemes like the Boiler Upgrade Scheme (BUS), the Warm Homes Local Grant, and GBIS operate in England and Wales. Scottish homeowners access equivalent support through Home Energy Scotland and Warmer Homes Scotland — often with better terms, including interest-free loans with cashback.

💡 After your solar installation: claim SEG payments
Scottish solar owners can earn money exporting surplus electricity to the grid via the Smart Export Guarantee (SEG). With Scotland's solar radiation levels, a 4kWp system typically exports 500–900 kWh/year — worth £75–£180 at average SEG rates.

Does Scotland have its own solar grant scheme?
Yes. Scotland has several devolved energy grant schemes that operate independently of the England and Wales programmes (ECO4, BUS, GBIS). The main route for solar panels in Scotland is the Home Energy Scotland (HES) Grant and Loan scheme, run by Energy Saving Trust on behalf of the Scottish Government. This provides interest-free loans of up to £15,000 for solar panels and heat pumps, plus cashback grants of up to £7,500. Lower-income households may also qualify for Warmer Homes Scotland, which funds free measures including solar and heating upgrades.
What is the Home Energy Scotland Grant and Loan?
The Home Energy Scotland Grant and Loan is Scotland's flagship scheme for homeowners wanting to install renewable energy systems, including solar PV panels, heat pumps, battery storage, and solar thermal. It provides an interest-free loan of up to £15,000 to cover installation costs, repaid over up to 12 years. Additionally, a cashback grant is available: up to £2,500 cashback on solar PV panels, £7,500 cashback on heat pumps, and £1,500 on battery storage. The loan element means you get the system installed now and pay back gradually — with your energy savings often covering the repayments.
Who qualifies for the HES Grant and Loan?
To qualify for the Home Energy Scotland Grant and Loan, you must: own your home in Scotland (homeowners only — not renters), have the property as your main residence, not have received previous HES funding for the same measure in the last 5 years, and have your property assessed as suitable for the technology. There is no income requirement for the loan — it is open to all Scottish homeowners. The cashback element is also available to all, though Warmer Homes Scotland provides additional free support for lower-income households.
What is Warmer Homes Scotland?
Warmer Homes Scotland is a Scottish Government programme providing free energy efficiency measures to lower-income households. It targets owner-occupiers and private tenants who are in or at risk of fuel poverty. Eligible measures have included insulation, heating systems (including heat pumps), draught-proofing, and in some cases solar panels. Households qualify if they receive qualifying benefits (Universal Credit, Pension Credit, Housing Benefit, etc.) or have a low income and live in an energy-inefficient home. Apply via Home Energy Scotland on 0808 808 2282.
Can I get both a HES loan and Warmer Homes Scotland?
Not typically for the same measure — double funding is not permitted. However, a household might receive Warmer Homes Scotland funding for insulation and then use the HES loan for solar panels separately, as these are different measures. Home Energy Scotland advisers will help identify which combination works for your situation. Call them on 0808 808 2282 for a free assessment.
Does Scotland have ECO4?
Yes — ECO4 applies in Scotland as well as England and Wales. Scottish households who receive qualifying benefits (Universal Credit, Pension Credit, etc.) and have an EPC rating of D or below can access free solar panels, insulation, and heat pumps through ECO4 via their energy supplier — the same as in England. The ECO4 Scotland route runs until March 2026. The successor, the Warm Homes Plan, will be replaced in Scotland by continued Warmer Homes Scotland funding under the devolved block grant.
What is the Area-Based Scheme in Scotland?
The Scottish Government's Area-Based Scheme (ABS) targets entire communities with the highest levels of fuel poverty and poorest housing stock — particularly in rural and island communities. Rather than individual applications, local authorities identify eligible streets or estates and arrange whole-area upgrades. If your community has been identified for ABS funding, you may receive free insulation and heating improvements regardless of your income. Contact your local council to find out if ABS projects are planned in your area.
