Suitability Requirement in Procurement Law 2026

Suitability requirement in procurement law: minimum requirements for bidders set by the contracting authority. Permissible criteria, proportionality and evidence.

Definition: Suitability requirements are the minimum conditions set out by the contracting authority in the procurement documents that a bidder or candidate must meet in relation to authorisation to pursue the professional activity, economic and financial standing, and technical and professional ability in order to participate in the award procedure.

Last updated: January 2026 · Legal basis: Directive 2014/24/EU Article 58, BVergG 2018 §§ 70–82, GWB § 122, VgV §§ 42–48

What are suitability requirements?

Suitability requirements are the procurement-law-compliant method by which contracting authorities ensure that only capable and suitable companies take part in award procedures. They are defined by the contracting authority before the procedure begins, published in the contract notice and the procurement documents and are binding on all bidders.

Suitability requirements must be confined to the three categories listed in Article 58 of Directive 2014/24/EU. Requirements outside those categories – for example, purely economic-policy criteria – are not permissible under procurement law.

Permissible categories of suitability requirements

Authorisation to pursue the professional activity

Contracting authorities can require bidders to be entered in a relevant professional or trade register or to hold a particular administrative authorisation. Examples:

Entry in the commercial register
Trade registration for the tendered activity
Authorisation as a tax adviser, lawyer, architect, etc.

Economic and financial standing

Requirements concerning the financial strength of the bidder may include:

Minimum annual turnover (overall or contract-specific)
Submission of balance sheets or annual financial statements
Evidence of professional indemnity insurance
Creditworthiness evidence (bank reference)

The minimum turnover required must not in general exceed twice the estimated contract value (Article 58(3), second subparagraph, of Directive 2014/24/EU).

Technical and professional ability

Requirements concerning expertise, experience and resources:

Reference lists of comparable contracts from the past three to five years
Evidence of specialists with specific qualifications
Technical equipment and capacities
Certifications (e.g. ISO 9001, ISO 27001 for IT security)
Quality assurance measures

Principle of proportionality

Suitability requirements are subject to the principle of proportionality: they must relate to the subject matter of the contract and must not unduly restrict competition. This is a key safeguard against excessively restrictive suitability requirements that would in practice only allow certain large companies to participate. Procurement chambers and courts examine the proportionality of suitability requirements closely.

Impermissible suitability requirements include, for example:

A minimum annual turnover that is many times the contract value
A requirement for a particular company size without objective justification
Reference requirements that only a few companies can meet

Publication duty and binding effect

Suitability requirements must be fully published in the contract notice before the procedure starts; subsequent changes or additions are in principle not permitted. The contracting authority is bound by the published requirements and may not interpret them differently to favour or disadvantage individual bidders.

Possible forms of evidence

Bidders may demonstrate compliance with suitability requirements through various forms of evidence:

European Single Procurement Document (ESPD): Preliminary self-declaration that must be accepted as standard above the EU thresholds
Suitability evidence: Official certificates, attestations and documents
Reliance on third-party capacity: Use of third-party capacities (Article 63 of Directive 2014/24/EU)

FAQ

May a contracting authority change suitability requirements during the procedure? No. Suitability requirements must be published before the procedure starts and are binding. Subsequent changes breach the principle of equal treatment.

Can a bidder challenge suitability requirements? Yes. Excessive or discriminatory suitability requirements can be challenged in review proceedings before the procurement chamber or the Federal Administrative Court (Austria), provided this is done in good time before the bid deadline expires.
