Tender Debriefs: Your Rights and How to Use Them (2026)
A tender debrief is feedback from the buyer on your submission. It tells you your scores, where you underperformed, and why you won or lost. It is one of the most commercially valuable things available to any tendering organisation — and one of the most consistently underused.
Most organisations request a debrief after a loss. Fewer request one after a win. Almost none analyse the feedback systematically and apply it to the next submission. The organisations that do are the ones with the highest long-term win rates. For the complete overview of how the tendering process works, see our guide to tendering for contracts.
Your Legal Right to a Tender Debrief
You have a legal right to request a debrief after any above-threshold public sector procurement. Under the Procurement Act 2023, contracting authorities must provide feedback to unsuccessful suppliers on request. This right applies to every supplier that submitted a tender — not just those who were shortlisted.
The buyer must respond within a defined period. They must provide your scores on each evaluated criterion. They must explain the reasons for the award decision. And they must — where possible — provide comparative information showing how the winning submission scored against yours.
This is a significantly stronger transparency requirement than the previous regime. Use it. Every debrief you receive and act on directly improves your competitive position in the next submission.
What Information a Debrief Must Include
Under the Procurement Act 2023, the award decision notice sent during the standstill period must already include your scores and those of the winning supplier. The debrief builds on this. It provides the qualitative explanation — why your submission scored as it did, what the winning submission did differently, and what specifically would have earned higher marks.
A complete debrief should tell you four things. First, your score on every evaluated criterion. Second, the winning supplier’s score on every criterion where comparison is possible. Third, the specific weaknesses in your responses that reduced your scores. Fourth, any compliance issues — missing documents, exceeded word counts, or failed mandatory requirements.
If the debrief you receive does not cover all four areas, ask follow-up questions. You are entitled to enough information to understand your result and improve for the next submission.
How to Request a Tender Debrief
Request the debrief immediately after receiving the award decision notice. Do not wait. For unsuccessful submissions on above-threshold contracts, the standstill period gives you a limited window — and you may want to use the debrief information to assess whether a challenge is warranted. Our guide to the standstill period covers this process.
Send your debrief request in writing — email to the named procurement contact is standard. Reference the contract name and number. State that you are requesting a debrief under the Procurement Act 2023. Ask specifically for your scores on each criterion, the reasons for the decision, and any comparative scoring information available.
For below-threshold contracts, buyers are not legally required to provide a debrief. However, most will provide informal feedback if asked professionally. Always request it regardless of threshold — the information is valuable.
How to Use Debrief Feedback Effectively
Receiving a debrief is the start, not the end. The value is in what you do with the information. Most organisations read the feedback, feel relieved or disappointed, and file it away. The organisations with the highest win rates treat every debrief as a specific, actionable brief for improvement.
After every debrief, do three things systematically.
Map the feedback to your submission. Read the feedback against the specific questions and responses it refers to. Identify exactly which section underperformed and why. Was it insufficient evidence? An unanswered question component? Generic methodology? Weak social value? The feedback names the problem — your submission shows you where it appeared.
Identify patterns across multiple debriefs. A single debrief tells you what went wrong on one bid. Five debriefs from similar contracts tell you what your organisation systematically underperforms on. Conduct win loss analysis across your last three to five submissions. The pattern is where the improvement is.
Update your bid library and standard content. If the debrief identifies that your methodology responses are consistently generic, update your standard methodology content before the next submission. If your social value commitments are consistently scored as lacking local specificity, build a more locally tailored approach into your standard preparation process. Apply the learning systematically — not just to the next similar bid but to your approach overall. Our bid review checklist includes a debrief learning check as a standard step before every new submission.
Debrief After a Win
Most organisations only request debriefs after losses. This is a significant missed opportunity. A win debrief tells you exactly what scored highest — and why. That information is directly replicable on the next submission.
After every win, request the same debrief you would after a loss. Ask what your highest-scoring responses contained, ask what differentiated your submission from the shortlisted competitors, ask whether any sections underperformed even though you won overall. The answers tell you what to replicate and what to strengthen.
When a Debrief Suggests a Challenge
Most debriefs reveal a straightforward explanation for the outcome. Your evidence was insufficient. A question component was not fully addressed. Your price was outside the competitive range. These are improvement areas — not grounds for a formal challenge.
Occasionally, a debrief reveals something more concerning. Evaluation criteria applied inconsistently. Scores that do not correspond to the mark descriptors. A procedural irregularity. If the debrief raises these concerns, you may have grounds to appeal. Our guide to appealing a bid decision covers what constitutes valid grounds for a formal challenge and what the process involves.
Frequently Asked Questions About Tender Debriefs
How quickly should I request a tender debrief?
Immediately — on the same day you receive the award decision notice. For above-threshold contracts, the standstill period runs for eight working days from notification. If you want to assess whether a challenge is warranted, you need the debrief information as quickly as possible. For below-threshold contracts, there is no standstill period — but early request still signals professionalism and gets you the information while the buyer’s memory is fresh.
Can a buyer refuse to provide a debrief?
For above-threshold procurements, no — the Procurement Act 2023 requires buyers to provide feedback on request. They cannot simply decline. However, they may limit the information provided to what is legally required. If you believe the debrief is insufficient, ask specific follow-up questions. Reference your right to feedback under the Act. Escalate to the buyer’s senior responsible officer if necessary.
What should I do if the debrief reveals very low scores?
Treat it as valuable intelligence, not as a verdict. Low scores on specific criteria tell you exactly where to focus your improvement effort. Review the relevant sections of your submission against the mark descriptors. Identify what a higher-scoring response would have contained. Build that content into your approach before the next similar submission. Consistent low scores on the same criterion across multiple bids indicate a systematic weakness — address it at the process level, not just in the next individual response.
How do I compare my debrief scores to the winner’s?
The award decision notice sent during the standstill period should include both your scores and the winning supplier’s scores. If the notice does not include comparative scoring, ask for it specifically in your debrief request. Buyers are required to provide this information where it is available. The comparison shows you not just where you lost marks but how many marks you would need to recover to win a similar contract.
Should I share debrief feedback with my whole team?
Yes — selectively and constructively. Share the specific feedback relevant to each team member’s contribution. The person who wrote the methodology section should see the methodology feedback. The pricing lead should see the price evaluation feedback. Whole-team awareness of the patterns across multiple debriefs — without individual blame — is one of the most effective ways to build a consistently improving submission process.
Does a debrief ever lead to a contract being re-awarded?
Rarely — and only where a formal challenge is commenced and succeeds. A debrief alone does not change the award decision. However, a debrief that reveals a genuine evaluation error or procedural breach provides the basis for a formal challenge that could result in the decision being reconsidered. Our guide to appealing a bid decision covers what happens when a challenge is pursued.
