ECO Energy Companies Obligation

The Energy Companies Obligation (ECO) is a government energy efficiency scheme for Great Britain which has replaced the Carbon Emissions Reduction Target (CERT) and the Community Energy Saving Programme (CESP) programmes, both of which came to a close at the end of 2012. It operates alongside the Green Deal and places obligations on larger domestic energy suppliers to domestic householders, with a focus on vulnerable consumer groups and hard-to-treat homes.
