ECO4 Scheme Extended to December 2026: What You Need to Know
✅ Good news: ECO4 has been extended!
The ECO4 scheme has been extended to 31st December 2026, giving eligible homeowners across Wales and South West England more time to access free energy upgrades.
The ECO4 scheme has been extended and now runs until December 31st, 2026. If you've been thinking about upgrading your home's energy efficiency in Wales or South West England, there's still time — but don't leave it too late.
What is ECO4?
The Energy Company Obligation (ECO4) is a government scheme that requires large energy suppliers to fund energy efficiency improvements in homes across Great Britain. Since its launch, ECO4 has helped thousands of households across Wales and South West England reduce their energy bills and carbon footprint through measures like boiler upgrades, insulation, and heat pumps.
Why has it been extended?
The government has extended ECO4 to December 2026 to ensure continuity of support for eligible households while the new Warm Homes Plan is finalised. This is great news for homeowners who haven't yet had a chance to apply — there's now more time to take advantage of the scheme.
What does this mean for homeowners in Wales and South West England?
If you're eligible for ECO4 funding, you now have until December 31st, 2026 to take advantage of the scheme. Homeowners in Swansea, Cardiff, Neath, Bristol, Bath, and surrounding areas should check their eligibility now — installation slots fill up quickly, and the process takes time from survey to completion.
You may be eligible for ECO4 if:
- You receive certain benefits (Universal Credit, Pension Credit, Child Benefit, etc.)
- Your household income is under £31,000
- You have a health condition made worse by living in a cold home
Don't wait — installation slots are limited
Even with the extension, installation slots are limited and the process takes time. From initial eligibility check to completed installation typically takes around 2 months. The sooner you apply, the sooner you'll benefit from lower bills and a warmer home.
