Short answer. Before a tender, a buyer may consult the market and take advice from companies like yours, as long as that doesn’t distort competition (Article 40). Taking part is lawful and often useful: you can find out what is coming and help the buyer write requirements that a real market can meet. The price is visibility. If you helped prepare the procedure, the buyer must take measures so that you don’t start with an advantage. That usually means passing the relevant information you exchanged to every other bidder and giving them enough time (Article 41). Exclusion is a last resort. It’s allowed only where nothing else can keep the competition fair, and only after you’ve had the chance to show that your involvement doesn’t distort it. So take part, but assume that anything relevant you say may end up in front of your competitors.

EU law · What Article 40 allows

“Before launching a procurement procedure, contracting authorities may conduct market consultations with a view to preparing the procurement and informing economic operators of their procurement plans and requirements” (Article 40). For that purpose a buyer “may for example seek or accept advice from independent experts or authorities or from market participants”. It may use that advice to plan and run the procedure, “provided that such advice does not have the effect of distorting competition and does not result in a violation of the principles of non-discrimination and transparency”.

Three things follow from the wording:

• It’s optional. The buyer may consult. Nothing in the Directive obliges it to, or prescribes a format. Questionnaires, meetings, information days and written requests for information all fit. You’ll also see it called market engagement, a market survey or a request for information (RFI). The Directive’s term is “market consultation”.
• It works in both directions. Its purpose is to prepare the procurement and also to inform the market of the buyer’s plans and requirements.
• It has a limit. Advice from market participants may be used only if it doesn’t distort competition or breach non-discrimination and transparency. That limit applies throughout, together with the general principles of equal treatment, transparency and proportionality (Article 18(1)).

A related tool is the prior information notice. Buyers “may make known their intentions of planned procurements” by publishing one (Article 48(1)). It isn’t a consultation in itself, but it is often the first public sign that a contract is coming.

EU law · If you took part: Article 41

Article 41 applies where a candidate or tenderer, or an undertaking related to it, “has advised the contracting authority, whether in the context of Article 40 or not, or has otherwise been involved in the preparation of the procurement procedure”. So it isn’t limited to formal consultations. A feasibility study, a pilot or a draft specification you wrote for the buyer can count too.

The buyer must then “take appropriate measures to ensure that competition is not distorted by the participation of that candidate or tenderer”. The Directive names two measures that these must include:

1. Sharing information. The buyer must communicate to the other candidates and tenderers the “relevant information exchanged in the context of or resulting from the involvement” of the company concerned.
2. Time. The buyer must fix “adequate time limits for the receipt of tenders”.

Exclusion is the last resort. The company concerned “shall only be excluded from the procedure where there are no other means to ensure compliance with the duty to observe the principle of equal treatment”. Before any exclusion, it “shall be given the opportunity to prove that their involvement in preparing the procurement procedure is not capable of distorting competition”. The measures taken must be documented in the procurement report under Article 84.

The same situation appears among the optional exclusion grounds: a buyer may exclude “where a distortion of competition from the prior involvement of the economic operators in the preparation of the procurement procedure, as referred to in Article 41, cannot be remedied by other, less intrusive measures” (Article 57(4)(f); see exclusion grounds).

Where the rule comes from

Article 41 writes down a principle the Court set out under the earlier Directives. In Fabricom (Joined Cases C‑21/03 and C‑34/03, 3 March 2005), Belgian law barred anyone who had carried out research, experiments, studies or development for a contract from bidding for it. The Court held that the Directives preclude such a rule where the person “is not given the opportunity to prove that, in the circumstances of the case, the experience which he has acquired was not capable of distorting competition” (ruling, point 1). It also held that a buyer can’t keep a related undertaking out of the procedure until the end of the examination of tenders where that undertaking says it has gained no unfair advantage (ruling, point 2).

What the later case law adds

Nothing direct so far. On 11 October 2026 we searched the 198 judgments and orders that the EU Publications Office links to Directive 2014/24, or to Directive 2004/18 from 14 July 2016. 154 have an English text. None interprets Article 40 or 41. Two orders and judgments describe preliminary market consultations run by the European Commission for its own purchases, under the EU’s Financial Regulation rather than the Directive (for example T‑38/21, where the Commission sent a survey to industry associations and, on that basis, drew up a database of potential suppliers). They show what a consultation can look like in practice, but they say nothing about Articles 40 and 41. The method is described in our analysis of the scoring formula.

EU law · What happens to what you share

Two rules pull in different directions:

• Confidentiality. Unless the Directive or national law provides otherwise, the buyer “shall not disclose information forwarded to it by economic operators which they have designated as confidential, including, but not limited to, technical or trade secrets and the confidential aspects of tenders” (Article 21(1)).
• Equal information. Where you were involved in preparing the procedure, the buyer must pass the “relevant information exchanged” to the other candidates and tenderers (Article 41).

The Directive doesn’t say how the two fit together in every case. It does make clear that the duty in Article 41 attaches to relevant information, and that confidentiality must be designated. Information you never marked as confidential is the easiest to pass on.

National law · Where your country may add rules

National law can say more about how consultations are announced and documented, and about access to information (Article 21(1) refers to national legislation on access to information). Check the national rules and any consultation notice before you send material.

Our analysis · What you share, and where it may end up

This table is our reading of Articles 21, 40 and 41. The documents and national law can change the answer for a given procedure.

Three made-up situations.

• A supplier answers a questionnaire about available technologies and price ranges. It hasn’t drafted anything for the buyer. Answering can count as advising the buyer, so Article 41 applies (“whether in the context of Article 40 or not”). The buyer publishes a summary of the answers with the tender documents. That is the kind of measure Article 41 names, and with it in place, exclusion would be hard to justify.
• An engineering firm wrote the feasibility study that the tender is based on and now wants to bid for the works. The buyer publishes the study and extends the tender deadline. If it still considers exclusion, it must first give the firm the chance to show that its involvement can’t distort competition (Article 41; Fabricom, ruling point 1).
• A subsidiary of a bidder advised the buyer. Article 41 covers “an undertaking related to a candidate or tenderer”. The bidder should expect the same measures as if it had advised the buyer itself.

Practice · Taking part without losing out

1. Read the consultation notice. Who will see the answers? Will a summary be published? Is there a confidentiality procedure?
2. Decide what you’re willing to see in a competitor’s hands. Anything relevant may be passed on. Share what helps the buyer and doesn’t hand away your edge.
3. Mark confidential material, and explain why. Article 21(1) protects information you designate as confidential. A general stamp on every page is weaker than a specific reason for a specific item.
4. Argue for functional requirements. It’s legitimate, and safer, to ask for a specification written in terms of performance or with “or equivalent” than for one that matches your product (see technical specifications).
5. Keep a record of meetings, questions and documents exchanged, with dates. If your involvement is questioned later, it’s your evidence.
6. If you prepared material for the buyer, expect it to be published and the deadline to be set with that in mind. If exclusion is raised, ask in writing for the chance to show that your involvement doesn’t distort competition (Article 41) and for the measures considered.
7. Once the tender is published, questions go through the formal clarification route, and answers go to every tenderer (see clarification questions).
