The Energy Companies Obligation (referred to as ECO1), which ran from January 2013 to March 2015, was a Government scheme for Great Britain that placed legal obligations on larger energy companies to deliver energy efficiency measures to domestic premises.

There were three main obligations under ECO1 which energy companies were required to meet. The obligations were the Carbon Emissions Reduction Obligation (CERO), the Carbon Saving Community Obligation (CSCO) and the Home Heating Cost Reduction Obligation (HHCRO). CSCO also had a sub-obligation focused on rural areas (the CSCO rural sub-obligation).

Below we have published the final report for ECO1 which details our final determinations on energy companies’ achievement against their obligations.

Suppliers continue to be obligated to deliver energy efficiency measures under ECO2 and we will continue to provide regular monthly public reports.
