PSQ and participation

Three tests, three moments. Participation is only the first.


Conditions of participation test legal, financial, and technical capacity: proportionate, timed to the buyer’s request, and separate from exclusion grounds and award criteria. Missing pre-award insurance alone is not failure. Part of our guide on UK public procurement.

Takeaways

  • Participation, exclusion, and award are different tests: prepared separately, answered separately.
  • Core supplier information goes through the platform once, then confirmed per procurement.
  • Performance insurance cannot be required in place before award; commitment plus evidence is the permitted form.

What are conditions of participation?

The buyer’s proportionate conditions on legal capacity, financial standing, and technical ability to perform, set under section 22 of the Procurement Act 2023, assessed separately from the award criteria under section 23, with the Cabinet Office conditions of participation guidance setting out what proportionate means in practice. Proportionate is doing real work in that sentence: conditions must fit the contract, not the buyer’s anxiety. What they are not: exclusion grounds (which live in Schedules 6 and 7 and belong to exclusions and debarment) and not award criteria, which score the tender rather than qualifying the tenderer. Which procedure stages each answer belongs to is on open versus competitive flexible.

What do you prove, and when?

  • Core supplier information. Standard company, financial, and compliance particulars via the central platform, confirmed per procurement, timed to the buyer’s request, not re-proven from scratch each time.
  • Financial capacity. What the buyer proportionately requires, noting audited accounts cannot be demanded unless company law (or an overseas equivalent) requires an audit; alternative evidence must be assessed where audit is not legally required.
  • Technical ability. Track record, resources, and key capability matched to this contract, evidenced, not asserted.
  • Association routes. Consortium membership, subcontracting, or guarantees can carry capacity the bidder alone lacks, structured deliberately, with the buyer’s direction rights understood.
  • Security evidence. Certifications and controls timed to the pack; the matrix is on Cyber Essentials and ISO 27001.

Timing follows the buyer’s timetable under equal-treatment duties; the pack’s dates govern, and the same dates bind all tenderers. Confirm timing, form, and the exact questionnaire wording against the current conditions-of-participation guidance and the buyer’s documents before relying on any summary here.

What is the insurance-timing rule?

Current guidance restricts requiring performance-related insurance to be in place before award. The permitted condition is commitment: the supplier will hold the required levels on commencement, evidenced by certificates or an insurer letter plus commitment, verified before award. Legal-requirement cover, such as employer’s liability type obligations, may still be required outright. The practical consequence: do not no-bid a UK tender solely for lacking the full insurance tower at submission, and do not treat the commitment as free, because the premium lands before first revenue.

What does this mean for the bid/no-bid call?

A participation condition unmeetable at the buyer’s date (financial standing, technical evidence, committed cover) is a capacity fail in week one. An exclusion ground is a different, harder conversation owned by specialists. An award criterion is scored, not gated. Keep the three tests in three columns and the call stays honest.
