Who qualifies for the Home Energy Scotland Glazing Loan in 2026
The loan is available to owner-occupiers and private-sector tenants in Scotland, provided the tenant has the landlord’s written consent. The property must be your main home, second homes, holiday lets, and buy-to-let properties are not eligible. You also cannot have received a similar Home Energy Scotland loan for the same glazing measure in the past 10 years (Home Energy Scotland, 2026).
If you live in a flat or maisonette, the building must be your primary residence, and you must have a legal interest in the property (freehold or long leasehold). Social housing tenants (council or housing association) are not eligible for this loan, though they may qualify for other schemes through their landlord.
Step-by-step application process for the 2026 glazing loan
Applying for the Home Energy Scotland Glazing Loan is straightforward, but following the correct order is essential to avoid delays.
Step 1: Check your property’s eligibility. Use the online eligibility checker on the Home Energy Scotland website, or call their free advice line on 0808 808 2282. They will confirm whether your property type and location qualify (Home Energy Scotland, 2026).
Step 2: Get at least one quote from a registered installer. You do not need multiple quotes, but the installer must be registered with either the Microgeneration Certification Scheme (MCS) or TrustMark for glazing work. Ask the installer to confirm their certification before proceeding.
Step 3: Apply online or by post. Complete the application form with your quote, property details, and proof of ownership (such as a recent council tax bill or Land Registry title) or landlord consent if you are a tenant. You can upload documents via the online portal or post them to Home Energy Scotland.
Step 4: Receive a loan offer letter, then order the work. Once approved, Home Energy Scotland will send you a loan offer letter. You do not pay upfront, the loan is paid directly to the installer after the work is completed and verified. The installer must provide a completion certificate before the funds are released (Home Energy Scotland, 2026).
What the loan covers, approved glazing types and U-value requirements
The loan covers double glazing, triple glazing, secondary glazing, and energy-efficient doors. All installed products must meet minimum thermal performance standards set by Building Standards Scotland (Section 6, Energy). For windows, the maximum U-value is 1.6 W/m²K. For doors (solid or glazed), the maximum U-value is 1.8 W/m²K (Home Energy Scotland, 2026).
Secondary glazing is also eligible, provided it meets the same U-value standard of 1.6 W/m²K. The loan cannot be used for repairs or replacement of existing double glazing that is already in good condition, it is intended for upgrading single-glazed or poorly performing windows and doors.
You can combine the glazing loan with other Home Energy Scotland loans for heating systems or renewables, but you cannot use two loans for the same measure. For example, you could take a glazing loan for windows and a separate renewables loan for a heat pump, but not two glazing loans for the same property.
The direct answer How to get the Home Energy Scotland Glazing Loan in 2026
You apply through Home Energy Scotland after getting a quote from an MCS- or TrustMark-registered installer, and the loan is interest-free for up to 10 years, covering up to £7,500 for windows and doors. No upfront payment is required; the loan is paid to the installer after work completion. The loan is available only to owner-occupiers or private tenants with landlord consent in Scotland (Home Energy Scotland, 2026).
How to verify your installer, MCS certification and TrustMark registration
For glazing work to qualify for the loan, your installer must be registered with either the Microgeneration Certification Scheme (MCS) or TrustMark. These schemes ensure the installer meets industry standards for quality and consumer protection. To verify an installer, use the MCS Installer Database at mcscertified.com or the TrustMark website at trustmark.org.uk. Both databases are free to search and list all registered companies (MCS, 2026; TrustMark, 2026).
If the installer is not registered on either scheme, the loan will not be approved. Always ask the installer to confirm their certification before getting a quote.
