M15 Acceptance Criteria
The M15 Acceptance Criteria document defines the acceptance criteria for M15, including the Meter Point Administration Number (MPAN) states that will be ‘acceptable’ and ‘unacceptable’ at M15.
M15 is planned to take place in October 2026, and is currently defined as ‘Full Transition Complete’, i.e., all MPANs have been migrated to the MHHS arrangements and none remain in the legacy arrangements.
The M15 Acceptance Criteria document was approved and baselined to v1.0 at the Testing & Migration Advisory Group (TMAG) (now the Migration & Cutover Advisory Group (MCAG)) meeting on 20 December 2023.
Minor updates were made to this document as part of the third Migration Framework consultation. These consultation Artefacts were approved by MCAG on 25 February 2025.
