Summary of Workshop Workload 15 Dec, 2010 Harmonisation Working Group

DR1031 – V2.0 Change to COS Registration for Keypad Change Request This Discussion Request proposes to change the Change of Supplier (CoS) process for a keypad meter where no physical metering changes, meter configuration changes or energisation are required. The current enduring solution process is as follows: when a Supplier sends in MM 010 CoS keypad Registration the customer is obliged to contact NIE to complete the Keypad CoS on the keypad meter e.g. manually perform Retained Credit and CoS processes which will also include providing codes, reads and the new Keypad Premise Number to the customer over the telephone and the ordering of the new Keypad Premise Card to be sent to the customer. This Discussion Request proposes that the New Supplier will be responsible for contacting the customer to perform the retained credit process when the customer is at the physical keypad meter and within the timeframe in order to complete the Change of Supplier process. The New Supplier may also provide CoS Reads on 210 MM, which must be taken and dated the same day as the retained credit has been completed and received within the specified timeframe. DR was discussed recently in a round of Supplier Workshops DR updated to V2 to reflect the discussions at these Workshops At today’s Meeting Approval to MCR and Approval 15 Dec, 2010 Harmonisation Working Group
