Within the Ofgem Switching Programme (OSP) that will introduce the Central Switching Service (CSS) it is expected that the source of the Meter Asset Provider identity (MAP Id) for gas Registrable Meter Points (RMP) will be the UK Link system. This data will be passed to CSS within a Synchronisation flow. Population and maintenance of the MAP Id will need to consider which industry party or parties will provide and retain responsibility for maintaining the MAP Id to the UK Link systems.

Part A of this Change was implemented as part of Minor Release Drop 4.

Part B of this Change was implemented as part of June 2020 Release.

Part C is a CSS deliverable and has been approved to be added to the scope for the November 21 Release
