What is suitability evidence?

Suitability evidence is the formal documentation with which bidders in an award procedure record and credibly substantiate their suitability vis-à-vis the contracting authority. The type of evidence required depends on the suitability criteria of the specific procedure and must be stated by the contracting authority in the contract notice and the procurement documents.

European procurement law distinguishes between preliminary evidence (in particular the European Single Procurement Document) and final evidence (official certificates and documents).

European Single Procurement Document (ESPD)

The European Single Procurement Document (ESPD) is the central instrument for simplifying suitability evidence above the thresholds. It is a self-declaration by the bidder confirming in advance that it meets the suitability criteria required and that no grounds for exclusion apply. The ESPD is a standardised EU form (Implementing Regulation (EU) 2016/7) and must be accepted as preliminary suitability evidence by all contracting authorities above the EU thresholds.

Only the bidder anticipated for award subsequently has to submit the full evidence (with a possibility for the contracting authority to request it).

Types of suitability evidence

The evidence required depends on the category of suitability requirement.

Evidence of authorisation to pursue the professional activity

Extract from the commercial register (no older than six months)
Trade licence or administrative operating permit
Evidence of membership of a professional chamber
Concession, licence or administrative authorisation

Evidence of economic and financial standing

Annual financial statements / balance sheets for the last two to three financial years
Bank references or financing evidence
Evidence of professional indemnity insurance (policy, insurance confirmation)
Turnover certificate (where appropriate, audited by a public accountant)

Evidence of technical and professional ability

Reference list of comparable contracts with contract volume, period of performance and contact persons at the reference giver
CVs and qualification evidence for the staff intended for the contract
Certification evidence (ISO 9001, ISO 14001, ISO 27001, etc.)
Equipment lists and inventories of technical resources
Subcontractor lists

Subsequent request for suitability evidence

Contracting authorities are in principle entitled and obliged to request missing or incomplete evidence later, provided this does not unduly favour the bidder. § 56 VgV and the corresponding national rules allow missing documents to be requested within a reasonable time. What is substantively a mandatory part of the bid itself cannot be requested later.

Currency and validity

Suitability evidence must as a rule be up to date; many contracting authorities set a maximum age (e.g. no older than six months). For official certificates, the issuing deadlines of the competent authorities must also be observed. Expired evidence can lead to exclusion.

Pre-qualification

Pre-qualification is an upstream procedure in which companies demonstrate their suitability once and can use the result for multiple award procedures. In Germany, the chambers of industry and commerce, chambers of crafts and sector-specific associations operate pre-qualification bodies. In Austria, the ANKÖ system (Contractor Register of Austria) offers comparable services.

FAQ

Must a bidder submit all suitability evidence with the bid? Above the EU thresholds, the ESPD is sufficient initially. Full suitability evidence only has to be provided by the bidder anticipated for award.

What is the difference between the ESPD and traditional suitability evidence? The ESPD is a self-declaration by the bidder without external confirmation. Traditional suitability evidence consists of official documents issued by third parties (authorities, certification bodies).

Can a contracting authority waive suitability evidence? Below the thresholds, a simplified suitability check based on self-declaration is possible. Above the thresholds, the statutory minimum requirements are mandatory.
