The Back Boiler Replacement Grant is part of the UK Government’s ECO4 Scheme, designed to help eligible households replace old, inefficient back boilers with modern, energy-efficient combi boilers completely free of charge.
Back boilers, typically found behind fireplaces, are outdated and expensive to run. Replacing them not only reduces your energy bills but also makes your home safer and more eco-friendly. If you’re on qualifying benefits or meet certain income or property conditions, you could be eligible.
