ECOES
ECOES is a website that allows authorised parties to search for supply details (past and present) using such things as the 13-digit MPAN bottom line number, the meter serial number or the postcode. The user can determine a wide range of data relating to the supply including the full address, meter details, the current energisation status and also the appointed parties (i.e. the supplier, distributor, MOP, DC and DA). The site is populated by MPAS.
