7. Update on Action Items Action Item 278
RMDS to investigate why both suppliers are not currently being contacted as outlined in WP13
Working Practice needs to be amended so that both suppliers are advised of duplicate MPRN scenario
The current level of duplicate MPRNs is 2 to 3 per month
One Supplier maintains if a duplicate MPRN is registered and then de-registered as a result of ESB Networks identifying the MPRN as a duplicate, the supplier will have incurred costs signing up that MPRN and there doesn’t appear to be a mechanism to recoup these costs.
Feedback requested. 7
