0784S - Transition to the Central Switching Service and the Retail Energy Code v3.0

This Modification details the transitional arrangements that will be required to the Uniform Network Code (UNC) in order to implement the Central Switching Service (CSS) and transition to the Retail Energy Code version 3.0 (REC v3). This Modification will assist the technical transition of mastering data items (including the Registration) from UNC to REC. For the avoidance of doubt there is a separate Modification under the Significant Code Review (SCR) that will enact the REC v3.

Impacted Codes (cont): Transitional arrangements are considered within REC Transition Schedule, in addition to the Ofgem Faster Switching Programme artefacts. Consequential impacts will be required to other Codes as a result of that implementation. This Modification deals specifically with the impact to the UNC. Impacts to IGT UNC will need to be assessed during development of this Modification. An equivalent IGT UNC Modification will be developed as necessary.
