concerned tenderers

Concerned tenderers is a legal term in public procurement that describes all suppliers who have participated in a procedure and are entitled to be notified of the award decision. The concept defines who the contracting authority is obligated to inform before signing the contract with the winning supplier.

Who qualifies as a concerned tenderer?

Under EU Directive 2014/24/EU and the Remedies Directive 2007/66/EC, a concerned tenderer is any economic operator that has submitted a bid in the tender procedure and has not yet been definitively excluded. Candidates — those who sought an invitation to participate in a restricted or negotiated procedure — are also considered concerned if they have not yet received notification that their application was rejected.

In practice: if five suppliers submit tenders and all are qualified, all five are concerned tenderers. If two were excluded during prequalification and notified accordingly, only the three remaining are concerned.

What rights do concerned tenderers have?

The Remedies Directive and Directive 2014/24/EU grant concerned tenderers several key rights:

• Notification: The contracting authority must send an award decision notice to all concerned tenderers simultaneously
• Statement of reasons: The notice must include the name of the winner and a summary of the relevant reasons based on the award criteria
• Standstill period: A standstill period of at least 10 calendar days (15 days for non-electronic communication) must pass before the contract can be signed
• Right to challenge: Concerned tenderers may seek interim measures or file a formal review if they believe the award was unlawful

If the winning tenderer is the only concerned tenderer, the standstill period does not apply — there is no one else to protect. Tools like Cobrief help suppliers monitor award decisions and key deadlines, ensuring the window for challenging a decision is not missed.

Concerned tenderers is a cornerstone concept in procurement law. It ensures that all participants who have invested time and resources in a competition have a genuine opportunity to verify that the process was fair and to act before the contract becomes final.
