What is the ECO4 scheme in Scotland?
ECO4 is a UK Government scheme funding free insulation, solar panels, and heating upgrades for low-income Scottish households on qualifying benefits, running until December 2026.
ECO4 is the fourth phase of the Energy Company Obligation scheme, which requires larger energy suppliers to fund energy efficiency improvements in low-income and vulnerable households across Great Britain. In Scotland, ECO4 works alongside other schemes like Warmer Homes Scotland to tackle fuel poverty and reduce carbon emissions.
Who Qualifies for ECO4 in Scotland?
You typically need a qualifying benefit like Universal Credit or Pension Credit, plus an EPC rating of D–G — both criteria must be met.
To qualify for ECO4 in Scotland, you must meet TWO criteria:
Eligibility Criteria
1. Receive a Qualifying Benefit
- Universal Credit
- Pension Credit (Guarantee or Savings Credit)
- Income Support
- Working Tax Credit
- Child Tax Credit
- Child Benefit (if household income under £31,000)
- Housing Benefit
- Jobseeker's Allowance (income-based)
- Employment and Support Allowance (income-related)
2. Have an EPC Rating of D-G
Your home must have an Energy Performance Certificate (EPC) rating of D, E, F or G. If you don't know your EPC rating, we can check this for you during your free eligibility assessment.
Important: Both Criteria Required
You must meet BOTH requirements to qualify for ECO4. If you are not on a qualifying benefit but have a low income, you may be eligible for Warmer Homes Scotland instead. Call 0141 230 0198 for advice on which scheme suits you.

What else do people ask about ECO4 in Scotland?
Common questions cover cost (it's genuinely free), tenancy rules, EPC requirements, and whether you can combine multiple measures — answered below.
Is ECO4 really free?
Yes, ECO4 is completely free for qualifying households. The energy companies are legally required to fund these improvements as part of their obligations under the scheme. There are no upfront costs, no hidden fees, and nothing to pay back.
How long does ECO4 run until?
ECO4 has been extended and now runs until December 2026. This gives qualifying households plenty of time to apply and have energy efficiency improvements installed.
Can I get ECO4 if I am a private tenant?
Yes, private tenants can qualify for ECO4, but you will need permission from your landlord as the improvements become part of the property. We can help you discuss this with your landlord and explain the benefits to them.
Can I get ECO4 if I am a homeowner with no benefits?
No, ECO4 requires you to be receiving a qualifying benefit. However, if you have a low income (even without benefits), you may qualify for Warmer Homes Scotland instead. Call 0141 230 0198 and we will advise you on the best option.
What if my EPC rating is A, B or C?
Unfortunately, homes with EPC ratings of A, B or C do not qualify for ECO4, even if you are on qualifying benefits. However, if your home genuinely has poor energy efficiency, the EPC may be outdated. We can arrange a new assessment.
Can I get solar panels and insulation through ECO4?
Yes, many qualifying households can receive multiple measures through ECO4. For example, you might get loft insulation, cavity wall insulation AND solar panels installed — all at zero cost. The exact measures depend on your home needs and current energy efficiency.
