ECO Scheme Grants

The Energy Company Obligation (ECO) is a government energy efficiency scheme in Great Britain to help reduce carbon emissions and tackle fuel poverty.
The scheme began in April 2013, and over time it has been amended. The ECO3 scheme closed on 31 March 2022.
The latest policy, ECO4, applies to measures completed from 1 April 2022 and will cover a four year period.
