28. Update on Action Items Action Item 278 (WP13 Duplicate MPRNs)
RMDS to investigate why both suppliers are not currently being contacted as outlined in WP13
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. 28

29. Action 278 (WP13) Response Specific Cases:
One recent example of the dual registration issue has been identified:
MRSO is reviewing this and will revert to the supplier
Any provided examples will also be reviewed 29

30. Action 278 (WP13) Response (contd.)
Working Practice
This has been further amended. When there are 2 registrations:
Database will recommend an MPRN for deletion based on the registration history and the technical aspects
MRSO will decide which MPRN to terminate
It requires approval for implementation 30
