How do I get access to ECOES?

Access to ECOES is almost always restricted to MRA parties. Electricity Suppliers and Distribution Business will however be set up with ECOES access once Market Assurance clears a Party for Controlled Market Entry (CME) and has an MPID live in MDD. Upon completion of both stages MRASCo will instruct the ECOES Service Provider to create a Company Group for the Party.

Meter Operators, PPMIPs, Data Aggregators, Data Collectors, Meter Asset Providers and other electricity agents may also be entitled to access ECOES. Once an Agent has an MPID live in MDD MRASCo will instruct the ECOES Service Provider to create a Company Group for the Agent.

I’m an electricity customer and have been told my address details are wrong in ECOES, can you correct this for me?

Data in ECOES is a reflection of that held in Registration Systems and as such must be corrected ‘at source’. This correction should be initiated by your current Supplier.

I have a number of Meter Serial Number updates however they have not been changed on ECOES, what should I do?

MRASCo cannot make any changes to ECOES, this is a MOPs responsibility to ensure changes to ECOES are made.

How much does access to ECOES cost?

This is determined on a case by case basis. Assuming the CAS accepts the request, the applicant and the CAS will agree the proposed terms of access and costs and charges. This will include costs for admin, data access, audit and any bespoke reports or extracts which need to be created. The agreed terms and costs will be subject to MEC agreement.

What is ECOES?

ECOES (the Electricity Central Online Enquiry Service) is funded by electricity suppliers and distributors and governed under the Master Registration Agreement (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.
