Understanding the ECO4 Boiler Scheme
Background: What is the ECO4 Scheme?
The Energy Company Obligation (ECO4) is a government-backed scheme designed to reduce fuel poverty and carbon emissions across the UK. Launched as the fourth phase of the ECO initiative, ECO4 places legal obligations on major energy suppliers to fund the installation of energy-efficient heating measures—including free boiler replacements—for eligible households.
