How the Scheme Works

The ECO4 flex scheme in London operates under the broader energy company obligation framework, where large energy suppliers fund home energy efficiency improvements.

The Importance of Flexible Eligibility

Flexible eligibility under the ECO4 flex scheme in London allows local authorities to declare households eligible even if they don’t receive qualifying benefits. This is essential for addressing fuel poverty in London boroughs such as Lewisham and Ealing, where many homes are older and less efficient. Councils issue a statement of intent, setting eligibility criteria for approval. This inclusive mechanism enables more residents to access grants, insulation upgrades, and heating improvements, creating warmer homes, reducing carbon emissions, and lowering energy costs for vulnerable households.
