The Warm Homes Plan 2026–2027
The UK Government's Warm Homes Plan is the successor to the ECO4 scheme, announced in January 2026. It will provide continued support for energy efficiency improvements with a higher income threshold and a greater focus on low-carbon heating.
Warm Homes Plan Key Facts
What is the Warm Homes Plan?
The Warm Homes Plan is the UK Government's next phase of energy efficiency support, announced in January 2026. It is designed to succeed the ECO4 scheme when it ends on 31 December 2026, and will provide continued funding for home energy efficiency improvements — including insulation, low-carbon heating systems, and smart heating controls — for eligible households across England, Scotland and Wales.
How Does the Warm Homes Plan Differ from ECO4?
The key differences between the Warm Homes Plan and ECO4 are: The Warm Homes Plan has a higher income threshold of £36,000 per year (compared to approximately £31,000 under ECO4's LA Flex route), it places a greater emphasis on low-carbon heating solutions such as heat pumps and solar panels, and it is expected to be more directly funded by the Government rather than solely through energy supplier obligations.
Should I Wait for the Warm Homes Plan?
No. If you are eligible for a free boiler grant under the current ECO4 scheme, you should apply now rather than waiting for the Warm Homes Plan. ECO4 funding is available until 31 December 2026, and there is no guarantee that the Warm Homes Plan will cover gas boiler replacements in the same way. The Warm Homes Plan is expected to focus more heavily on low-carbon heating alternatives such as heat pumps.
Important: ECO4 funding ends on 31 December 2026. If you qualify for a free boiler grant, apply now to avoid missing out. The application to installation process typically takes 4–8 weeks.
