Vulnerable Customers DR to implement CER decision in advanced stage of drafting Main elements in proposal: Replace the 2 existing special needs flags in the data model with a new single ‘customer attribute’ flag. This will affect the relevant CoS, CoLE and CoCD messages. Allow multiple segments on this field in messages to cover e.g. visually impaired, elderly. Add validations to prevent the creation of de-energisation calls for elderly during designated winter months and life support all year. Add validations to prevent scheduling such a call created earlier for life support or elderly within the designated months. Use existing correspondence address functionality to facilitate the sending of ESBN correspondence to a carer address where a visually impaired customer requests it of a supplier. Addition of attribute flags to printed work instructions and selected call screens. Next stage will be to issue revised Discussion Request

E.g. New Connections, Meter Re-configurations. The purpose of this item is to allow Suppliers to identify which meter has been exchanged for which new meter in the case of like for like exchanges. A like for like exchange can be defined as the exchange of one meter for another with the same configuration e.g. a Day / Night Meter for a Day / Night Meter. It is proposed to provide this item only where a like for like meter exchange has taken place. i.e. not for New Connections or where a meter has been re-configured from NQH to QH or where a non like for like exchange has taken place.
