The Eco4 Boiler Replacement Grant
Is part of the UK government’s efforts to encourage homeowners to upgrade their heating systems and improve the energy efficiency of their homes. By installing a new, high-efficiency boiler, homeowners can reduce their energy bills and reduce their carbon footprint. The grant is non-repayable and is based on the results of a free energy assessment, which is carried out prior to installation. The assessment considers the energy efficiency of the home, the type of boiler being replaced, and the age of the existing system.
