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