Use the actual criterion, submitted evidence and assessment reason to decide whether the next bid needs better writing, a better offer or more capacity.
An unsuccessful UK bidder can use an assessment summary to identify a weak submission, a weak offer or a mismatch with the buyer's priorities. Those are different problems. The score alone rarely explains which one caused the result; the useful evidence is the connection between the published criterion, the assessed tender and the buyer's reason for the score.
The government's assessment summaries guidance, updated in August 2026, describes the information suppliers should receive under the Procurement Act 2023. It gives a disciplined starting point for a commercial review because it explains both the required assessment information and the limits of what the summary must contain.
Section 50 requires a summary for each assessed tender; guidance explains the final-stage scope. A tender rejected at an earlier stage of a competitive flexible procedure is not an assessed tender for this purpose. Official guidance nevertheless recommends prompt written feedback for unsuccessful intermediate-stage suppliers, using an appropriate level of explanation and a similar structure.
This distinction affects how a company interprets the result. Failure to progress from participation can concern organisational capacity or the selection method. Losing after a final tender can concern the proposed offer's assessment against award criteria. A sales meeting that calls both outcomes a price loss can send the next bid in the wrong direction.
Framework call-offs and direct awards have different treatment: the guidance says the statutory assessment-summary requirement does not apply to those awards in the same way. It does apply when awarding a framework that is itself a public contract. Identify the procurement route before deciding what information the buyer should have supplied.
Regulation 31 requires simultaneous provision; section50 places the summaries before the contract award notice. The notice starts the standstill period; receipt of the summary does not itself start that period. Official guidance does not prescribe a fixed interval between sending summaries and publishing the notice.
Save the summary's receipt time and the notice reference separately. They serve different purposes: one records when the explanation reached the company, and the other identifies the formal procurement event. The UK contract award notice and contract-details distinction explains why the award notice should not be read as proof that the contract has already been entered into.
The commercial learning exercise should begin promptly while the bid team remembers its choices. If the company needs to assess a possible legal challenge, that is a separate decision requiring attention to the actual procedure and applicable deadlines. Do not let a scheduled internal lessons meeting become the organisation's only response to a time-sensitive concern.
Regulation31 specifies criteria, relative importance, assessment method and available scores. It may refer suppliers back to the full methodology instead of reproducing it. Retrieve that version, especially if documents changed during a multi-stage procedure.
Create a compact record with one line for each assessed criterion or subcriterion: available score, awarded score, stated reason and the relevant passage in the submitted tender. Include subtotals where the published method uses them. This recreates the buyer's assessment structure before anyone introduces a theory about the overall outcome.
Use the actual submitted file. Working drafts can contain a strong explanation that was shortened, removed or placed in an attachment the buyer did not assess. Reviewing the version the team wishes it had sent produces a misleading account of the result and obscures the specific editorial or approval decision that changed the evidence.
Consider a hypothetical service proposal assessed on mobilisation, continuity and support. The buyer accepts the mobilisation timetable but says the support answer names roles without demonstrating how absence cover will work. The company has an established cover arrangement, yet the submitted answer does not describe it.
That is initially an evidence problem. The next response needs to explain who covers the role, how they gain access to the relevant work and how the arrangement sustains the promised service. It does not automatically require hiring another permanent employee. The business should confirm the arrangement exists before rewriting the answer, then use the actual operating model to support the claim.
If the review instead reveals that nobody can cover the specialist, the issue is delivery capacity. A clearer paragraph would only make the gap more visible. The corrective action belongs with the service owner and pricing team, because providing the missing capacity can change costs and staffing. Both situations may produce similar scores, but they require different investments.
An unsuccessful supplier receives information about its own assessed tender and the assessment of the most advantageous tender, subject to applicable treatment of sensitive information. The buyer is not required to produce a direct comparison of every sentence in the competing offers.
Regulation31 requires reasons linked to relevant tender information; restating a criterion does not provide that connection. It also recognises that commercially sensitive information may need to be withheld, while the remaining explanation should still allow the score to be understood. The bidder should look for the described outcome or evidence that earned credit, rather than assume it has received the winner's full solution.
For a framework with several successful suppliers, the guidance recommends using the lowest-scoring successful tender as the relevant comparison for an unsuccessful bidder. That is useful commercially: it can show the gap to entry. It does not describe every appointed supplier or establish that all winners offered an identical delivery model.
An absent score is not necessarily a clerical omission. Where the methodology provides for assessment to stop after a failed pass/fail criterion, the buyer need not assess every remaining criterion. The summary should explain the failure and the extent of the assessment.
Before projecting how a lower price might have changed the result, check whether the tender progressed far enough for that price to matter. A hypothetical discount calculation has little meaning if a mandatory technical threshold had already ended the assessment. The immediate learning task is to understand the threshold and the evidence used to assess it.
A useful clarification request identifies the criterion, the stated score, the relevant submitted evidence and the specific uncertainty. This gives the buyer something concrete to address. A broad request to explain why the company lost is less likely to resolve whether the issue was absent evidence, interpretation of a commitment or an unresolved delivery concern.
Assign each substantiated weakness to an owner and a deliverable. An evidence gap might require a verified service example; a pricing problem might require a revised delivery model; a capacity gap might require a partner agreement before the company pursues comparable work. Keep those changes tied to the assessment that justified them.
For future competitions, the guide to investment across a competitive flexible procedure helps decide when to fund that improvement. A stronger submission library is useful only when its examples and commitments remain true for the next offer. The valuable outcome of the review is a better-supported commercial decision about which work to pursue and what the company must change to compete credibly.
