MP200 Faster Switching consequential changes to the SEC

Several SEC Sections and Appendices must be amended in order to facilitate the go-live of the Centralised Switching Service (CSS). These changes are deemed as consequential changes that will have a minor, if any, impact on SEC Parties.

In order to successfully deliver the Faster Switching Programme, consequential changes must be made to the SEC. The detailed amendments have been provided by the DCC and can be found in Annex A.
The current obligations for Network Parties to ensure RDPs send registration data to the DSP will be removed. These will be replaced with obligations on the DCC in its role as the Centralised Registration Service (CRS) to ensure the CSS sends the required registration data to the DSP. Suppliers and Other SEC Parties remain unaffected by any SEC consequential changes.
In addition to clarifying obligations on the CRS, changes will also be required to the SEC Appendices that detail the new interface between the DSP and CSS systems. The DSP and the CSS systems Service Provider are currently discussing the detailed design for these interfaces.
To ensure that there were no unintended consequences, the Proposed Solution was presented to both the Security Sub-Committee (SSC) and the Technical Architecture and Business Architecture Sub-Committee (TABASC) in late June/early July 2021. The proposed changes were subsequently presented to the Panel to confirm they are ready for inclusion in the upcoming Ofgem Significant Code Review.
Furthermore, Ofgem issued a consultation to the wider industry to understand their opinions of the Proposed solution and the legal text. There were no responses to the consultation.
