Ofgem Energy Company Obligation (ECO) Eligibility System
This function allows you to search an individual postcode.
The results table show you if a postcode is in an eligible CERO Rural or CSCO area, and if so under which ‘eligibility criteria’ and ECO time period it is eligible. For information on the different eligibility criteria and ECO time periods please refer to the help page.
You should note that postcode boundaries may move over time so you may wish to repeat the search at a later date. This database will be updated on a quarterly basis.
Note: CSCO will close at midnight on 31 March 2017 so this tool should not be used to identify CSCO eligible postcodes after this date.
