Bidder Suitability in Procurement Law 2026

Bidder suitability: the bidder- and company-related requirements for participation in public award procedures. Criteria and evidence.

Definition: Bidder suitability refers to the personal, professional, economic and financial conditions that a company taking part in an award procedure must meet to be eligible for contract award.

Last updated: January 2026 · Legal basis: Directive 2014/24/EU Articles 57–64, BVergG 2018 §§ 70–82, GWB § 122, VgV §§ 42–48

What is bidder suitability?

Bidder suitability is the bidder- and company-related element of bid review and ensures that only capable, reliable and qualified companies are awarded public contracts. In award procedures, bidder suitability is generally checked before the substantive examination and evaluation of the bid. A bidder that does not meet the suitability requirements must be excluded from the procedure – regardless of how strong the bid otherwise is.

Bidder suitability is to be distinguished from the general concept of "suitability": "suitability" describes the overall procurement-law concept, while "bidder suitability" emphasises the person-related aspect – the specific capability and reliability of the company participating in the procedure.

Components of bidder suitability

Bidder suitability is made up of several requirement areas that must all be met cumulatively.

Reliability and absence of grounds for exclusion

First, it is examined whether the bidder is subject to mandatory or discretionary grounds for exclusion (Article 57 of Directive 2014/24/EU). Mandatory grounds for exclusion – e.g. convictions for corruption, fraud or money laundering – lead to automatic exclusion. Discretionary grounds for exclusion (e.g. grave professional misconduct, tax arrears) can lead to exclusion at the contracting authority's discretion.

Authorisation to pursue the professional activity

The bidder must have the legal authority to provide the service tendered. This includes trade licences, registrations in professional or trade registers and sector-specific licences.

Economic and financial standing

The bidder must be financially stable enough to perform the contract. Contracting authorities may require minimum annual turnover, evidence of creditworthiness or adequate professional indemnity insurance.

Technical and professional ability

The bidder must demonstrate that it has the necessary expertise, experience, references and technical resources to perform the contract properly.

Timing and sequence of the check

Bidder suitability is in principle checked before bid evaluation; the sequence of the steps may, however, vary depending on the type of procedure. In multi-stage procedures (participation contest + bid stage), suitability is checked at the first stage. In single-stage procedures (open procedure), the contracting authority can, under § 42(1) VgV, limit the suitability check to the most economically advantageous bid (so-called "bid examination first").

Suitability check and equal treatment

The contracting authority is bound by the suitability requirements set out in the procurement documents and may not subsequently tighten or relax them during the procedure. Unequal treatment of individual bidders in the suitability check is a serious breach of procurement law and can lead to the procedure being annulled.

Bidding consortia

For bidding consortia, suitability is in principle assessed on the basis of the combined capability of all members. Grounds for exclusion, however, apply individually: a single member subject to a mandatory ground for exclusion can lead to the exclusion of the entire consortium where that member is to take on an essential role.

FAQ

Can a bidder that meets a ground for exclusion still be admitted? In certain cases, yes – if it credibly demonstrates that it has restored its reliability through self-cleaning measures (Article 57(6) of Directive 2014/24/EU, § 125 GWB).

When does the contracting authority check bidder suitability? In single-stage procedures after bid opening; in two-stage procedures already in the participation contest. The suitability check precedes the substantive bid evaluation.
