ECO4 Scheme Update – Can You Still Apply?

The UK Government’s ECO4 (Energy Company Obligation) scheme has helped thousands of households improve their home energy efficiency through funded upgrades such as boiler replacements, air source heat pumps, solar PV and insulation. Plumbwise has previously supported customers by processing ECO4 claims and delivering these improvements.

The scheme is now approaching its final phase. ECO4 is currently scheduled to run until December 2026, but it will not be replaced in the same form after this date. Instead, the Government plans to move towards a new programme known as the Warm Homes Plan, which will change how funding is delivered.

This means eligible households can still apply for ECO4 support now, but applications must be assessed, approved and installed before the scheme closes. As funding is limited and demand remains high, acting sooner rather than later is important.

ECO4 continues to focus on supporting people on lower incomes, those receiving qualifying benefits and households with poorly insulated homes. Grants may still be available for heating upgrades and energy efficiency measures, subject to eligibility and availability of funding.

Plumbwise continues to help customers understand their options, check eligibility and plan energy-saving improvements while ECO4 remains active. We also stay up to date with changes to Government schemes, so we can advise customers as new support programmes are introduced.

If you are wondering whether you can still apply for ECO4, or what will replace it, now is the best time to explore your options and secure any available support.

  • ECO4 is still open – eligible households can still apply for funded energy efficiency improvements while the scheme remains active.
  • The scheme is ending in 2026 – ECO4 will not continue in its current form, so acting now could help you secure support before it closes.
  • Support may be available for heating and insulation upgrades – including boilers, air source heat pumps, solar PV and home insulation, subject to eligibility.
  • Plumbwise can guide you through your options – from checking eligibility to advising on current and future energy efficiency schemes.
