ECOES

What is ECOES?

ECOES (the Electricity Central Online Enquiry Service - www.ecoes.co.uk) is funded by electricity Suppliers and Distribution Business and governed under the MRA. 

ECOES was designed to assist Suppliers in the customer transfer process by allowing the triangulation of data; it is also used to provide benefit to MRA parties in other key areas.

Access to ECOES Data

Access to ECOES is available to suppliers, distributors, supplier agents (e.g. Meter Operators and Data Collectors) and non-domestic customers. Other parties may be granted access if approved by the MRA Executive Committee (MEC) in line with the principles set out in MAP15.

In order to help Suppliers check that they have correct information about customers prior to a customer transfer, some of the data contained in ECOES is provided to suppliers on a monthly DVD.

MEC has agreed that some other parties may request access to ECOES data. In order to obtain access, third parties must complete an application process, sign a licence agreement and pay any agreed fees and charges. In addition, all users of ECOES information are subject to an annual information security audit.

The application process is administered by the Central Administration Service (CAS), provided by Gemserv. An application form is available to download below, along with a document providing guidance for third party users of ECOES. An example of an access licence and the governance surrounding access can also be downloaded below.
