About the ECO tool

We’ve developed this tool because we needed it to administer the Energy Company Obligation (ECO).


While we designed it to assist our administration, we’ve also made it publicly available to help others, such as energy companies, the wider supply chain and consumers.

Eligibility

Eligibility for CERO Rural and HHCRO Rural may differ and depends on when a measure was/is to be installed. This tool refers to these different time periods as ‘ECO2t’ and ‘ECO3’. The table below details the time period for each:

ECO Time Period Comments
ECO2t 01 April 2017 to 30 September 2018 The ECO2t extension ran from 1 April 2017 and introduced a rural minimum requirement under CERO.
ECO3 1 October 2018 to 31 March 2022 The ECO3 Order is going through the parliamentary process and is anticipated to come into force in winter 2018; there is a possibility it will not be in force on 1 October 2018. Under article 13 of the draft ECO3 Order measures that are completed between 1 October 2018 and the date the ECO3 Order comes into force can contribute towards ECO3 where they are compliant with the ECO3 Order. Rural delivery under ECO3 will also have to meet the household eligibility criteria outlined in our guidance.

You can find further information about the CERO Rural and HHCRO Rural requirements under ECO at our webpage Energy Company Obligation.
