Overview

The Scotland SME Loan Scheme is one of the most generous business decarbonisation finance products in the UK. Administered by Energy Saving Trust (EST) on behalf of the Scottish Government, it provides 0% interest loans of up to £100,000 for SMEs installing energy efficiency or renewable energy equipment — including commercial solar PV. The headline feature in recent years has been a cashback bonus of up to 50% of the loan value, meaning a £20,000 solar project can be funded by a £20,000 0% loan with up to £10,000 of that effectively converted into a grant.

Programme funding is set on an annual cycle; the cashback element has been particularly popular and the budget has sometimes run dry mid-year, so timing matters. The loan portion is repaid over 8 years from operating cashflow.

Eligibility criteria

  • Trading from premises in Scotland.
  • SME or third-sector status — under 250 employees, under £43m turnover. Sole traders qualify.
  • Project must be on the EST-approved equipment list (solar PV systems from MCS-certified installers are typically pre-approved).
  • Project must deliver verifiable energy savings or renewable generation.
  • You must have received an EST-approved energy audit or recommendation report before applying (EST will arrange one for free).
  • Subsidy control / state aid compliance — declare cumulative subsidies received.

How to apply

Step 1 — Request a free EST audit.

Energy Saving Trust will arrange a free site visit by an accredited assessor. The audit identifies which technologies suit your premises and qualify for the loan.

Step 2 — Receive the recommendation report.

Typically 2-4 weeks after the audit. The report lists eligible projects, indicative capex, projected savings and loan options.

Step 3 — Apply for the loan.

Online application via EST's portal — typically 30-45 minutes to complete with the audit data and an installer quote.

Step 4 — EST credit review.

Typical timeline 6-8 weeks. EST may visit your premises a second time before approval.

Step 5 — Sign the loan agreement.

Loan terms are typically 8 years, monthly direct debit. Cashback (if available) is paid as a credit against the loan balance after commissioning.

Step 6 — Project delivery and commissioning.

Funds released to your installer on milestones — typically 50% on mobilisation, 50% on commissioning evidence.

Step 7 — Repayment.

First payment typically falls 30-60 days after commissioning. Most loans allow early repayment without penalty.

Watch-outs and pitfalls

  • Cashback budget runs out. The cashback element has been oversubscribed in some years. Apply early in the financial year (April-July) for the best chance of cashback availability.
  • Audit is mandatory before application. You cannot apply for the loan without an EST audit and recommendation report. Build 4-8 weeks into your project timeline for the audit step.
  • Installer must be on the EST approved list. Most MCS-certified installers qualify automatically.
  • Cashback rules change annually. Check the current cashback percentage and any caps for your project type — the headline rate has been 50% in some years but lower in others.
  • Loan repayment is from your existing cashflow. Even though the energy savings typically cover the repayment, the loan creates a real obligation on the business balance sheet — directors are jointly and severally liable in some legal structures.
