Home Energy Scotland Solar PV and Battery Loan Guide

Key Takeaways

• The Home Energy Scotland Grant and Loan provides homeowners in Scotland with grants, interest-free loans, or a combination of both for clean heating and insulation.
• Clean heating systems such as heat pumps receive grant funding of up to £7,500, with an additional optional £7,500 interest-free loan.
• Energy efficiency improvements receive grant funding up to 75% of combined costs, capped at £7,500.
• Rural and island properties qualify for an additional £1,500 uplift on heating and efficiency grants, allowing up to £18,000 in total grant funding.
• Interest-free loan funding of up to £5,000 is available for solar thermal and hybrid solar PV / water heating (PV-T) installations.
• Installations must be delivered by certified Microgeneration Certification Scheme (MCS) contractors using certified products.

Overview of the Home Energy Scotland Funding Framework

The Home Energy Scotland Grant and Loan provides homeowners in Scotland a grant, interest free loan or a combination of both to install clean heating systems and energy efficiency measures. Funded by the Scottish Government and delivered via Home Energy Scotland and the Energy Saving Trust, the scheme supports homeowners transitioning away from fossil fuel heating systems.

To be eligible, the property must be an existing home located in Scotland, and the applicant must be the homeowner living in the property as their only or primary private residence. Importantly, applicants do not need to be in receipt of government benefits to qualify for funding support.

Clean Heating and Energy Efficiency Funding Allocations

Funding allocations under the scheme vary depending on the technological classification of the measure installed:

Heat Pumps and Clean Heating Systems

• For clean heating installations—including air source, ground source, and water source heat pumps, or heat network connections—grant funding of up to £7,500 is available.
• Homeowners can additionally access an optional interest-free loan of up to £7,500 to cover remaining installation costs.
• Only heat pumps that provide 100% of heating and hot water requirements are eligible for funding; hybrid heat pumps are not eligible for funding under the rules.

Energy Efficiency and Fabric Measures

• For building fabric measures such as insulation, grant funding is available up to 75% of the combined cost of measures, subject to a maximum grant cap of £7,500.
• Homeowners must provide a valid Energy Performance Certificate (EPC) recommending the specific fabric improvement.

Rural and Island Uplift

Recognising the higher logistics and supply chain expenses in remote geographies, an uplift of £1,500 is available for rural and island homes to both the heating and energy efficiency grants. This allows eligible remote households to claim up to £18,000 in non-repayable grant assistance.

Solar Technologies and Battery Storage Under the Loan Scheme

Homeowners planning solar installations must understand how the Scottish funding framework distinguishes between different microgeneration technologies:

Hybrid Solar PV-T and Solar Thermal Systems

Under the scheme's scheduled funding table:

• Solar thermal installations qualify for an optional interest-free loan of up to £5,000, though direct grant funding is not available.
• Hybrid solar PV / water heating systems qualify for an optional interest-free loan of up to £5,000.
• The scheme rules stipulate that only solar PV-T systems are eligible for funding under this category; standalone conventional solar PV is not funded via direct grants.

Quality Certification Requirements

All funded renewable technologies must adhere to strict quality standards:

• Installers must be certified under the Microgeneration Certification Scheme (MCS).
• Installed equipment must be certified under MCS or Solar-Keymark product standards.

Application Milestones, Deposit Drawdown, and Timelines

Navigating the application process requires adherence to statutory milestones:

1. Advisor Referral: Homeowners contact Home Energy Scotland (freephone 0808 808 2282) to discuss property eligibility and obtain an electronic application referral link.
2. Application Processing: After successful submission of the online application form with contractor quotes, the delivery team aims to process the claim within 10 working days.
3. Funding Offer and Agreement: Once a written funding offer is issued, the applicant must review and sign the funding agreement electronically within 14 days. Work must not commence prior to formal agreement execution.
4. Deposit Drawdown: To assist with upfront material costs, homeowners can claim a deposit drawdown of up to 60% of funding for renewable systems upon submission of an approved installer quote.
5. Completion Period: Homeowners have 9 months from signing the agreement to complete installations and submit their final completion claim with MCS certification.
