Common Questions About Energy Grants

Clear answers to the most common questions about energy funding schemes available to Scottish homeowners.

Last updated: February 2026|Reviewed for accuracy

General

Yes. Under schemes like ECO4, energy companies fund home improvements for eligible households. There is typically no cost to the homeowner if you meet the criteria.

Large energy suppliers are required by the UK Government to fund energy efficiency improvements in qualifying homes. The funding comes from obligations placed on these companies.

No. This is an independent informational resource. We aim to help Scottish homeowners understand what funding may be available. Always confirm details with official scheme providers.

Most schemes cover all of Scotland, including Glasgow, Edinburgh, Dundee, Aberdeen, and rural areas. Availability may vary by region and installer coverage.

Eligibility

Eligibility is usually based on your household income, any benefits you receive, your property type, and its current energy efficiency rating (EPC).

You can use our eligibility checker for an initial indication, then confirm with an official scheme provider.

Qualifying benefits typically include Universal Credit, Pension Credit, Income Support, Income-based JSA, Income-related ESA, Working Tax Credit, Child Tax Credit, and Housing Benefit.

Yes. Through the LA Flex (Local Authority Flex) route, households with annual income under approximately £31,000 may qualify, particularly if the property has a low EPC rating or occupants are vulnerable to cold.

In some cases, yes. Private tenants may be eligible but typically need written consent from their landlord before improvements can proceed.

Yes. The property must generally have an EPC rating of D, E, F, or G. The type of improvements offered will depend on the property construction and what measures would be most effective.

Possibly. If existing loft insulation is below the recommended 270mm depth, or if cavity walls are uninsulated, you may still qualify for improvements.

Schemes & Funding

ECO4 (Energy Company Obligation, Phase 4) is a UK Government scheme requiring large energy suppliers to fund energy efficiency improvements in qualifying homes. It runs until March 2026.

Warmer Homes Scotland is a Scottish Government programme that provides free energy efficiency improvements to homeowners receiving certain qualifying benefits.

Home Energy Scotland offers interest-free loans and cashback grants for energy efficiency improvements and renewable energy systems. Available to all Scottish homeowners, not just those on benefits.

Different measures may be funded through different schemes. A property assessment will determine which route is most appropriate for each improvement needed.

The current ECO4 scheme runs until March 2026. A successor scheme (ECO5 or similar) is expected but details have not been confirmed. Funding criteria can change.

Improvements

Depending on eligibility and property needs, improvements may include loft insulation, cavity wall insulation, solid wall insulation, boiler replacement, heating controls, and in some cases heat pumps or solar panels.

The specific measures will be determined by a property assessment. The aim is to improve the property to at least EPC band C (or D where C is not practically achievable).

Loft insulation typically takes a few hours. Cavity wall insulation takes 1-2 days. Boiler replacement takes 1-2 days. External wall insulation may take 2-4 weeks.

Loft and cavity wall insulation cause minimal disruption. Boiler replacement may require a day without heating. External wall insulation involves scaffolding and several weeks of work.

Yes. Work carried out under funded schemes must meet quality standards. Insulation typically has a 25-year guarantee. Boilers come with manufacturer warranties, usually 5-10 years.

Process & Timeline

From initial application to completed work, the process typically takes 4-12 weeks. This varies depending on the type of improvement, demand, and documentation requirements.

A qualified surveyor visits your property to assess its current energy efficiency, identify suitable improvements, and check that proposed measures are appropriate for the building type.

You will typically need to provide proof of benefits or income, proof of address, and consent for the work to proceed. The installer or referral agent will guide you through requirements.

Yes. Applications may be declined if the property does not meet criteria, if proposed measures are not suitable, or if funding allocations have been reached. Criteria can change over time.
