The ECO4 Scheme (Energy Company Obligation Phase 4) is a UK government-backed initiative designed to improve home energy efficiency while supporting low-income and vulnerable households. Introduced in 2022 as the latest phase of the long-running ECO program, ECO4 aims to reduce carbon emissions, cut energy bills, and ensure that more homes across the UK are warm, healthy, and affordable to heat.https://eco4homeimprovements.co.uk
