Boiler Grants in London- What you’ll get?

Low-income residents of London who own their homes or live as private tenants and receive certain government benefits can apply for the boiler replacement grant. It’s provided free of charge under the ECO4 scheme, aiming to transform every inefficiently heated home into a sustainable living space.
