You Think the Tender Evaluation Was Unfair. What Can You Actually Do?

Losing a tender you expected to win is frustrating on its own. Losing it and suspecting the scoring was wrong, inconsistent or quietly tilted towards the incumbent is worse, and most experienced bidders have had that feeling at least once. The difficult part is that feeling something was unfair and having a legal basis to challenge it are two different things, and the window to act on the second one is usually measured in days.

This guide sets out what an unsuccessful bidder can actually do after a disappointing result: what you are entitled to ask for, how long you have to act, what a formal challenge can and cannot achieve, and how to decide whether it is worth pursuing at all.

Quick answer

If you think a tender evaluation was unfair, ask the contracting authority for a debrief in writing on the day you receive the outcome. Under EU procurement law, every unsuccessful tenderer can request the reasons for the rejection of its tender. A tenderer whose bid was admissible can also request the characteristics and relative advantages of the winning tender and the name of the winner. The authority must normally answer within 15 days of your request.

At the same time, check the standstill period, the pause before the contract can legally be signed. In many systems, only formal proceedings started within that period stop the signature. Deadlines to challenge vary sharply by country, from as little as five days in some cases to 30 days or more in others, so treat the result as urgent from the moment it lands.

Disagreement with a score is not the same as an unfair evaluation

Every evaluation involves judgment. A panel scoring a technical answer 3 out of 5 instead of the 4 you expected is not, by itself, evidence of anything improper. It may simply be their assessment of how well you answered against the published criteria. Formal challenges succeed when there is a specific, evidenced breach of the rules the buyer had to follow, not because the losing bidder believes its answer was better.

The practical test is this: can you point to a specific rule, published criterion or legal principle that was breached, and can you back that up with something more concrete than your impression of the result? The legal principles behind that test are straightforward: buyers must treat suppliers equally, avoid discrimination, act transparently and keep requirements proportionate. Those principles come directly from Article 18 of Directive 2014/24/EU. On price, the same directive requires a buyer to ask for an explanation where a tender looks abnormally low for the work involved (Article 69). If the honest answer to the test is no, a debrief is still worth requesting for next time, but a formal challenge is unlikely to go anywhere.

Step one: request a debrief before you do anything else

Whatever you eventually decide, request a debrief the same day you receive the outcome. Article 55 of Directive 2014/24/EU sets out what you can ask for in writing. Any unsuccessful tenderer can ask for the reasons its tender was rejected. A tenderer that submitted an admissible tender can also ask for the characteristics and relative advantages of the tender selected and the name of the successful tenderer. The contracting authority must respond as quickly as possible and in any event within 15 days of receiving the written request.

There is a limit. Article 55(3) lets a contracting authority withhold certain of this information where releasing it would impede law enforcement, be contrary to the public interest, prejudice the legitimate commercial interests of a particular economic operator, or prejudice fair competition between operators. The clause covers both the information about the winner's bid and the reasons for your own result, so expect some detail to be redacted and ask for the rest.

Ask specifically for your score against each award criterion, not just a total; the scoring rationale or evaluator commentary if the buyer holds it; the winning bid's score against the same criteria; and the final ranking. A debrief that only gives you a pass or fail and a total score is much harder to assess than one broken down by criterion, so ask for the breakdown rather than accepting whatever is offered first.

The standstill period: why the clock is already running

Before a contracting authority can sign with the winning bidder, most contract awards covered by the EU procurement directives are subject to a standstill period, a mandatory pause between telling bidders the outcome and entering into the contract. There are exceptions, including some framework and dynamic purchasing system awards, cases where the winner was the only tenderer left in the running, and contracts where prior publication was not required. It is sometimes called the Alcatel period, after the 1999 Court of Justice case (C-81/98, Alcatel Austria) that led to it. Its purpose is to give unsuccessful bidders a real opportunity to seek a debrief and, if necessary, challenge the decision before the contract becomes binding.

Under the EU Remedies Directive (Directive 89/665/EEC as amended by Directive 2007/66/EC, Article 2a), the minimum standstill is 10 calendar days from the day after the award decision is sent, if it is sent by fax or electronic means. If other means are used, the minimum is either 15 calendar days from the day after dispatch or 10 calendar days from the day after receipt, depending on how the Member State has implemented the rule. Countries can set longer periods on top of this baseline, and the award letter must tell you the exact standstill period that applies.

In the United Kingdom, where a standstill applies under the Procurement Act 2023, the minimum period is 8 working days beginning with the day the contract award notice is published. The authority can set a longer period, and the notice must state the last day. Some awards are exempt under section 51, including certain framework call-offs, dynamic market contracts, light touch contracts and urgent direct awards, though a buyer may still run a voluntary standstill.

If a supplier both starts proceedings and notifies the contracting authority that it has done so during that period, the contract is automatically suspended and cannot be signed until the matter is resolved or a court lifts the suspension. Both steps are needed; starting the claim without telling the authority does not trigger the suspension. The Act governs contracting authorities in England, Wales and Northern Ireland, plus reserved and cross-border bodies in Scotland. Devolved Scottish authorities stay under Scotland's own procurement legislation, including the Public Contracts (Scotland) Regulations 2015.

The mistake many bidders make is waiting for the debrief before deciding whether to challenge, only to find the standstill has expired and the contract is signed. If you think you may want to challenge, say so in writing within the standstill window, even before your debrief is complete. Under the Remedies Directive, where an independent first-instance body reviews an award decision, the authority cannot conclude the contract until that body has decided on interim measures or on the review itself. A strongly worded email to the buyer, on its own, does not have that effect.

How long you have to challenge, and why it varies by country

There is no single European deadline for bringing a formal challenge. Each country runs its own review system with its own body and time limits, and the differences are large enough that assuming your neighbouring market works like your home market is a genuine risk. Four examples show the range.

Two things are worth taking from that table even without memorising the figures. First, several of these deadlines are measured in single-digit or low double-digit days. Second, some systems stack more than one deadline on top of each other; Germany is the clearest case, where missing the objection deadline can close the whole route regardless of how much time is technically left. Treat any figure in this guide as a starting point for your own check, not a substitute for confirming the current rule in the country where you bid, ideally with a lawyer who practises there.

What a formal challenge can actually achieve

Be realistic about outcomes before committing time and cost. Article 2 of the Remedies Directive requires every Member State to give its review body three powers: interim measures, including suspending the award procedure; setting aside unlawful decisions, including discriminatory specifications; and damages. On top of those, the remedies available in practice typically include:

• Interim measures, stopping the contract being signed while the challenge is heard. Automatic suspension usually depends on acting within the standstill period. Depending on national law, other interim relief may still be available before the contract is signed; the Remedies Directive requires review bodies to have that power but does not make it automatic.
• A declaration of ineffectiveness affecting a signed contract. The exact consequences are set by national law, which may cancel all contractual obligations retroactively or only those still to be performed. Under Article 2d the central case is a contract awarded without the required publication of a contract notice, an unlawful direct award. A breach of the standstill period leads to ineffectiveness only where it deprived you of pre-contractual remedies and is combined with another breach of the procurement rules that affected your chances of winning. A standstill breach on its own is not enough.
• An order to re-run the evaluation, or part of it, where the breach affected the scoring but not the legality of the whole procedure.
• Damages, where the breach caused you loss. Once a contract has been signed, national law may limit the review body to damages, and in practice damages are often the only realistic remedy once performance has started.

What a challenge only rarely achieves is the contract simply being reassigned to you. Courts and review bodies generally correct a flawed process rather than substitute their own judgment for the buyer's. The more likely outcomes are a re-run competition, a corrected evaluation or compensation, not an automatic win.

A decision checklist before you challenge

A challenge costs time, and usually money, even when it succeeds. Work through these questions honestly first:

• Is the contract value large enough that the likely remedy, whether re-run, correction or damages, justifies the legal cost?
• Do you have specific, evidenced grounds from the table above, rather than a general sense that you should have won?
• Do you still have time before the relevant deadline, including time to instruct a lawyer who knows the local procedure?
• Have you requested and reviewed the debrief, so you are challenging what happened rather than what you assume happened?
• Are you prepared for an adverse costs order if the challenge fails, where that risk applies in the relevant country?
• Is this a buyer you plan to keep bidding to, and if so, have you weighed the commercial side of a formal challenge against raising your concerns informally first?

If most of these point the wrong way, a formal challenge may not be worth it, but that does not mean saying nothing. Raising specific, evidenced concerns in writing to the buyer, naming the exact criterion or process point in question, can still prompt a useful response and is worth doing even when litigation is not.

The first 48 hours after a disappointing result

1. Request a written debrief immediately, asking for your score against each criterion, the winning bid's score against the same criteria, and the final ranking.
2. Check the standstill end date stated in the award letter for this specific procurement, not a general rule of thumb, and put it in the calendar.
3. Re-read the original tender documents and evaluation criteria before forming a view, so any objection is anchored to what was published.
4. Write down exactly what you believe went wrong while it is fresh, even if you have not decided whether to challenge.
5. If a formal challenge looks plausible, contact a lawyer who practises procurement law in that country before the standstill closes, not after.
6. Decide, using the checklist above, whether a formal challenge, an informal complaint, or accepting the result and improving the next bid is the right call.

Where Tendly fits in

This guide is general information, and the deadlines above are the reason to get case-specific help fast. Tendly offers it at three points: after a result you think is wrong, when a tender is cancelled and re-listed, and before you bid at all.

If you have already lost and the result looks wrong, Tendly's Appeal service starts with a free initial assessment. A tender expert reads the tender documents, the award decision and your debrief, and tells you whether the evaluation looks unfair and whether you have grounds to appeal. If you do, the team analyses the evaluation criteria, prepares the appeal, submits it on your behalf once you have approved it, and follows the case through to a re-evaluation or a reopened tender.

Not every unfair-looking result ends in an appeal. Instead of choosing a winner, a buyer can cancel the tender and re-list it with changed criteria, a familiar experience for companies bidding outside their home market. That normally means every participant rewriting and resubmitting its documents against the new requirements. Tendly's tender experts can adapt your existing submission to the new criteria quickly, so you stay in the competition rather than starting again from a blank page.

Before you bid, the same expertise comes through Tendly's Strategist service: a personal tender expert who checks which award criteria and weightings the buyer published, prepares your tender documents, keeps an eye on the outcome and works to increase your chances of winning.

Frequently asked questions

Is a debrief mandatory, or can a buyer refuse to give one?

Under Article 55 of Directive 2014/24/EU, a buyer must, on written request, give you the reasons your tender was rejected, and, if your tender was admissible, the characteristics and relative advantages of the winning tender and the winner's name, normally within 15 days. It may withhold certain information where disclosure would impede law enforcement, harm the public interest, prejudice a company's legitimate commercial interests or prejudice fair competition. A blanket refusal to explain your own result is not what the directive provides for.

What is the standstill period, in plain terms?

It is the mandatory pause between telling bidders the outcome and signing the contract with the winner. Its purpose is to give unsuccessful bidders a real window to seek a debrief and challenge the decision before it becomes hard to undo. The EU minimum is 10 calendar days after an electronic notification; national periods can be longer, and where a standstill applies under the UK Procurement Act 2023 the minimum is 8 working days.

Does starting a challenge cost money even if I lose?

In many countries, yes. Court or review-body fees, your own legal costs, and in some systems the risk of paying the other side's costs if you lose, are all realistic considerations. Factor them into the checklist above and ask a local lawyer about the cost exposure in that jurisdiction.

Will challenging a decision hurt my chances with that buyer in future?

It can affect the relationship, though public buyers are legally required to treat suppliers equally regardless of past challenges. Many experienced bidders raise informal, evidenced concerns first and reserve formal challenges for serious breaches, partly for this reason.

Can I challenge after the contract has already been signed?

Sometimes, but the options narrow. Once a contract is signed, stopping the signature is no longer available, and challenges typically shift towards damages or, in the more serious cases such as an unlawful direct award, a declaration that the contract is ineffective. Acting during the standstill period preserves more options.

Do these rules apply the same way in every country Tendly covers?

No. The debrief right and the standstill concept come from shared EU law, but the review body, the exact deadlines and the procedure are set nationally, and non-EU markets such as the UK and Switzerland run their own systems. Always confirm the current rule for the specific country before acting.

Key takeaways

A disappointing result is not automatically an unfair one, and the difference matters because formal challenges succeed on evidenced breaches of the rules, not on a stronger conviction that you should have won. What matters most in the first hours after a result is speed: request a debrief in writing immediately, find the standstill end date for that specific procurement, and get local legal advice quickly if a challenge looks realistic. In most European systems the window to stop a contract being signed is short and does not wait for your debrief to arrive.
