ECO 4 funding is a scheme in Scotland designed to improve the energy efficiency of homes and reduce carbon emissions. The program provides financial assistance to eligible homeowners, private landlords, and social housing providers to install energy-saving measures such as insulation, boilers, and also renewable energy technologies. The scheme is funded by the Scottish Government and also is part of the wider initiative to achieve Scotland's net-zero discharges target by 2045. ECO 4 is available up until 2026 and also is expected to provide substantial benefits to the environment, including a reduction in carbon emissions, lower energy bills for homeowners, and the production of environment-friendly work in the construction industry.
