What is the Free Boiler Scheme - ECO4 ?

To reduce UK energy consumption, the government has proposed a cost-effective solution – a free boiler scheme under ECO4. This scheme is available to vulnerable households across England, Scotland and Wales that qualify for assistance in improving their homes’ energy efficiency with an eligible gas, oil or LPG boiler up to five years old. Funded by  UK’s major utility providers through the Energy Company Obligation (ECO4) program – which allocated over £1.3 billion last year alone – this grant offers real financial support for families in need of improved heating solutions
