The event will comprise a series of presentations by the Authority, followed by optional one-to-one sessions with participating organisations. How to participate: Each organisation must indicate when registering whether it wishes to attend: • in person; or • virtually using Microsoft Teams. Attendance in either format is subject to confirmation by the Authority. Each organisation will be limited to one one-to-one session lasting no longer than 15 minutes. Due to time and capacity restrictions, the Authority may be unable to offer sessions to all attendees. Subject to the Authority’s final confirmation, sessions will be allocated on a first come, first served basis. The Authority reserves the right to determine the final allocation and scheduling of sessions. The one-to-one sessions are for preliminary market engagement only and will not be used to evaluate or down-select suppliers or solutions. Please note: This is an invitation-only event. Invitations will be extended only to organisations that formally register their interest by 17:00 GMT on Friday 30 October 2026 and whose attendance is subsequently confirmed by the Authority.

In-person attendees without confirmation will not be permitted entry, and virtual joining instructions must not be forwarded or shared with other individuals or organisations.
