ECO4 Scheme

The ECO4 scheme (Energy Company Obligation Phase 4) is a UK government programme that helps eligible households access funded energy-efficiency upgrades to make their homes warmer, more efficient, and cheaper to run.

The scheme is funded by large energy suppliers and focuses on supporting low-income, fuel-poor, and vulnerable households through improvements such as insulation and heating upgrades.

Improveasy supports the delivery of the ECO4 scheme by guiding households through eligibility checks and coordinating trusted, accredited installations.

What Is the ECO4 Scheme?

The ECO4 scheme is the latest phase of the Energy Company Obligation and runs from April 2022 to March 2026. It places a legal obligation on energy suppliers to fund energy-efficiency improvements in eligible homes.

Rather than offering a cash payment, the ECO4 scheme provides fully or partially funded upgrades, delivered through approved installers and managing agents.
