If they choose to switch they should apply to their new retailer, either directly or through an appointed intermediary, and enter into a contract with the retailer The new retailer should initiate a switch request. Industry standard processes should manage objections from the current retailer and necessary customer protections. The MO should manage most data exchange Market operator Current retailer Wholesalers When the switch is complete the MO should update a central register of service points which it maintains, and inform wholesalers if necessary. The central register will be developed top-down to produce a single record of the constable premises and service points The new retailer should be responsible for obtaining a switching meter read, which is communicated to the current retailer through industry processes. The current retailer should then issue a final bill which the customer then pays Contracts Data/communication flows Financial flows

The wholesaler should then invoice the retailer The whole process should be repeated after 2, 8 and 13 months to resettle for each settlement period Data/communication flows Financial flows

Click to edit Master title Systems architecture and data model Systems Architecture: To enable the MO to deliver its defined services IT systems will be required, e.g. a registration system and database; and a charge calculation system Data model: The data model for the market, and for the MO in particular, includes centrally held records of: premises, service points, and associated meters and market participants; service requests and notifications; and meter readings, wholesale charging schemes, and derived wholesale charges. The central data model will not hold customer-level data.
