The ECO4 Deadline: Your Last Chance for Government-Backed Home Efficiency

Time is running out for one of the UK’s most significant energy support programmes. The Energy Company Obligation, known as ECO4, is officially drawing to a close on December 31, 2026. For homeowners who have been waiting to improve their home’s efficiency—whether through insulation, heat pumps, or other measures—the final months of the year are the last opportunity to leverage this funding. ECO4 has been a vital tool for thousands of families, providing free or heavily subsidised energy efficiency upgrades, particularly for those in homes with an EPC rating of D or lower. Because there will be no "ECO5" follow-up in the same format, all work must be fully installed and commissioned by the year-end deadline. If you receive qualifying benefits, or if your property meets the local authority flexible eligibility criteria, you should act now. While other government grants like the Boiler Upgrade Scheme will continue to provide support for heat pump installations into 2027 and beyond, the breadth of support provided by ECO4 for fabric and heating improvements is unique. Don’t let this opportunity pass by; contact an approved installer immediately to assess your eligibility and start the process before the final cutoff.
