Options for the timings of upcoming CRM auctions Decision Paper (SEM-26-024)

In early 2026, the SEM Committee consulted on options for the timings of upcoming CRM auctions. Following review of the consultation feedback and further engagement with the SOs, the SEM Committee has decided on a solution that prepares for a glide-path towards a longer lead time, whereby the expectation is that there would be consecutive auctions for CY2031/32 and CY2032/33 held in late 2027/early 2028. Therefore, whilst auction timetables have not yet been set or approved, the SEM Committee anticipates the following indicative timeframes for upcoming T-4 auctions:

•    T-4 2030/31 to be held in Q1 2027;
•    T-4 2031/32 to be held in Q4 2027/Q1 2028; and
•    T-4 2032/33 to be held three months thereafter.

Certain auction processes for the latter two auctions would be run in parallel, the detail of which is provided in this paper.

Considerations on the longer-term auctions, including in relation to five-year lead times, will be developed through the CRM Development Programme, the next stage of which is intended to open for consultation in July 2026.
