S charges will be stopped provided that the Supplier accepts responsibility for transaction charges and appropriate additional charges (e. g. such as required to gain access) v NIE does not propose to change current arrangements for deregistration, MPRN termination and/or service removal v. These are driven by customer request or as a result of NIE fieldwork and observation v NIE consequently proposes: v. The current arrangements will remain in place v.
