170 for the 3 (three) weighted questions, and achieve a Pass for all other questions. If a potential provider achieves a score of “0- Unacceptable” against any of the 3 (three) weighted questions, this will result in the respondent being excluded from tendering for this requirement. The potential providers who have met the minimum pass criteria, will then be ranked (highest to lowest) on their combined score achieved against the 3 (three) weighted questions in Part 2. The Authority will take the highest ranking potential providers through to the ITT stage up to a maximum of 6 (six) Potential Providers. In a case of a tied ranking which identifies more than 6 (six) potential providers, the Authority will take forward the potential providers who have achieved the highest score for the weighted question (PSQ_2.3.1) If this still results in more than 6 (six) potential providers, the Authority reserves the right to increase the maximum number of potential providers to take through to the invitation to tender stage. Further details can be found within the "Supplier Guidance" published with the PSQ.

Commercial outcome & contract awards
Published awards, contracts and bid statistics — not a forecastAwards 1
| Awarded to | Value | Date | Status |
|---|---|---|---|
| supplier not published | — | 2 Feb 2026 | CancelledThe procurement is being abandoned due to: 1. All bids received were deemed to be commercially non-compliant, in-line with the ITT pack sent out to all invited bidders. As a result of this, all bids received were not brought forward to the second stage of evaluation (Technical Compliance). 2. Bidders submitted requests for material changes to the draft contract off the back of the self-reported non-compliance that have been deemed unacceptable. 3. The ITT pack outlined that negotiations do not apply to this tendering process, which the ITT rules do not permit the Authority to have further dialogue with the bidders to negotiate acceptable contracting positions. 4. The Authority is now reviewing its requirement for GSA9 Support and how any such requirement may be fulfilled in the future. Any future opportunities will be advertised on Defence Sourcing Portal. |
