Pre-Qualification Questionnaire (PQQ)

A Pre-Qualification Questionnaire (PQQ) is the selection stage document used in multi-stage procurement procedures to filter suppliers before they are invited to submit a full tender. It separates the question of whether a supplier is qualified from the question of who offers the best value. Only suppliers that pass the PQQ stage receive the invitation to tender documents, protecting both buyers and bidders from investing resources in a full tender evaluation that includes suppliers who should not have been in the competition at all.

What is a Pre-Qualification Questionnaire (PQQ)?

A PQQ typically covers three areas aligned with Article 58 of Directive 2014/24/EU:

Exclusion grounds. Suppliers declare whether they or their directors have been subject to criminal convictions, insolvency, serious professional misconduct, or other grounds that require or permit exclusion. See exclusion grounds and mandatory exclusion grounds for detail.

Economic and financial standing. Suppliers provide financial data to demonstrate they meet the minimum financial thresholds. This typically includes turnover figures, financial ratios derived from accounts, and evidence of insurance coverage. See economic and financial standing.

Technical and professional ability. Suppliers provide references for comparable past contracts, details of key staff, certification evidence (such as ISO 9001 and ISO 14001), and information about their delivery approach and capacity. See technical and professional ability.

Responses to a PQQ are assessed on a pass/fail basis against the minimum stated criteria, sometimes followed by a scored shortlisting stage where the criteria are applied to reduce the pool further. Only shortlisted suppliers proceed to the invitation to tender.

In the UK, the term PQQ has largely been replaced by the Selection Questionnaire (SQ), which introduced a standardised format across central government and devolved administrations. The underlying purpose is identical: to qualify suppliers before inviting bids.

In EU procurement, the European Single Procurement Document (ESPD) serves a similar function as a self-certification tool, with buyers specifying the criteria and suppliers completing the ESPD as a preliminary evidence declaration.

Why the PQQ Matters for Bidders

The PQQ stage is where many bids are eliminated before the buyer ever reads a commercial proposal. Common reasons for PQQ failure include: turnover below the financial threshold; insufficient reference contracts meeting the value or scope criteria; missing certifications; or incomplete or inaccurate responses. Each of these failures costs the supplier the entire bid investment without any opportunity to demonstrate value.

Treating the PQQ as a routine administrative step rather than a substantive evaluation is a strategic error. A well-structured PQQ response, with clear evidence, strong references, and complete answers to all questions, is the foundation of a winning bid.

Example

A Czech facilities management company responds to a PQQ for a national public building maintenance framework. The PQQ requires: minimum annual turnover of EUR 5 million; at least three references for comparable facilities management contracts each worth EUR 1 million or more in the last five years; and ISO 9001 certification. The company meets all three criteria and submits a well-organised PQQ with audited accounts, three strong references with contact details, and a current ISO 9001 certificate. It is shortlisted and invited to submit a full tender.

Frequently Asked Questions

Is the PQQ scored or assessed on a pass/fail basis?

Both approaches are used. Some PQQs apply a pure pass/fail assessment: suppliers either meet each criterion or they do not. Others use a scored shortlisting approach: suppliers that pass the minimum thresholds are then scored on additional criteria (such as the depth of their experience or the strength of their references) and the top-scoring suppliers are invited to tender. The procurement documents will specify which approach applies.

Can a supplier improve its PQQ response if it falls short?

Only within the limits of the procurement rules. Contracting authorities may ask for clarification of ambiguous responses but cannot allow suppliers to improve or supplement a materially deficient submission after the deadline. If the deadline has passed and the response is incomplete, the supplier is typically excluded.

How long is a PQQ response valid?

A PQQ response is valid for the specific procurement in which it was submitted. It does not create a standing qualification that applies to other procurements. Some framework agreements maintain approved supplier lists that function similarly to standing PQQ results, but each open competition requires a fresh submission.
