Competitive Dialogue

Competitive dialogue exists for procurements where the contracting authority genuinely does not know what the solution should look like. It is most common in complex infrastructure, public-private partnerships, large-scale IT transformation, and defence programmes where the technical, legal, and financial aspects are so intertwined that a detailed specification cannot be written without structured market engagement.

What is Competitive Dialogue?

Article 30 of Directive 2014/24/EU makes competitive dialogue available when a contract meets the "particularly complex contract" test: the contracting authority cannot objectively specify the technical means capable of satisfying its needs, or cannot identify the legal or financial structure of the project. It is a more demanding threshold than the one required for the competitive procedure with negotiation.

The procedure runs in three broad phases.

Phase 1: Selection. The contracting authority publishes a contract notice on TED describing its needs (not a full specification) and the applicable selection criteria. Any supplier may submit a request to participate. The buyer shortlists a minimum of three candidates who meet the criteria. The minimum period to submit a request is 30 days.

Phase 2: Dialogue. The contracting authority conducts structured dialogue with each shortlisted candidate separately during the dialogue phase. The purpose is to develop one or more solutions that best meet the buyer's needs. Dialogue may cover technical, legal, financial, and commercial aspects. It continues until the buyer has identified solutions capable of meeting its requirements. All information shared by candidates is treated as confidential and must not be disclosed to competing participants without consent.

Phase 3: Final tenders. Once dialogue is concluded, the buyer invites all remaining participants to submit final tenders based on the solutions developed. Final tenders are evaluated against the published award criteria. The buyer may clarify, specify, and optimise final tenders but may not fundamentally change the core elements agreed during dialogue.

In the UK, the Procurement Act 2023 merged competitive dialogue into the broader "competitive flexible procedure," giving buyers the flexibility to design a dialogue-type process without a separately named procedure.

Why it matters for bidders

Participating in competitive dialogue is resource-intensive. The dialogue phase can last many months and requires significant internal investment in developing and presenting solutions. However, shortlisted suppliers gain a direct channel to shape the eventual specification, which can create a competitive advantage if the buyer adopts elements of your solution as the basis for the final tender requirement.

Confidentiality obligations run both ways: your proposed solutions cannot be shared with competitors, giving you protection for commercially sensitive approaches disclosed during dialogue.

Example

A French rail authority needs to procure a next-generation train management system with a contract value of EUR 200 million. The technical architecture, data integration requirements, and operational model are undefined. It runs a competitive dialogue, shortlists four technology firms, conducts six months of structured technical and commercial dialogue with each, and then invites final tenders. The authority awards the contract on the basis of the most economically advantageous tender.

Frequently Asked Questions

How is competitive dialogue different from the competitive procedure with negotiation?

Both procedures involve structured engagement with shortlisted suppliers, but competitive procedure with negotiation requires the buyer to be able to define a minimum specification at the outset. Competitive dialogue is reserved for contracts where even the minimum specification cannot be defined without market input.

Can a buyer favour one candidate during the dialogue phase?

No. Contracting authorities must treat all candidates equally and must not provide information in a discriminatory manner. Sharing one candidate's proposed solution with a competitor is expressly prohibited by the directive.

Is there a minimum number of candidates for competitive dialogue?

Yes. Directive 2014/24/EU requires at least three shortlisted candidates, provided at least three economic operators meet the selection criteria.

Can a buyer award a contract without asking for final tenders?

No. Even after the dialogue phase concludes, the buyer must invite all remaining participants to submit final tenders and must evaluate them against published award criteria.
