Pre-Qualification Questionnaire: What It Is and How to Pass

A pre-qualification questionnaire (PQQ) is a first-stage assessment document buyers use to check whether suppliers meet the minimum eligibility criteria before inviting them to the full tender stage. Pass it and you compete for the contract. Fail it — through missing information, inadequate evidence or non-compliance — and you’re out before the scored quality questions begin. For the complete guide to the public sector procurement process, visit our pillar guide Tendering for Contracts.

What Is a Pre-Qualification Questionnaire?

A PQQ is a structured document issued at the first stage of a restricted procurement procedure. It asks suppliers for information about their organisation — financial standing, relevant experience, insurance, policies, accreditations and legal compliance — so the buyer can assess eligibility for the full tender stage. The PQQ is a gateway, not the award. Suppliers who pass are shortlisted and invited to submit a full tender response. Suppliers who fail are excluded — regardless of their actual delivery capability. The PQQ sits at the start of the restricted procedure. Our guide to types of tendering procedures explains where it fits in the full procurement timeline.

PQQ vs Selection Questionnaire — What Is the Difference?

The Selection Questionnaire (SQ) has largely replaced the PQQ in formal procurement language under the Procurement Act 2023. In practice, many buyers and suppliers still use PQQ as shorthand. Both terms describe the same first-stage eligibility assessment — you’ll encounter both across the UK public sector. Our dedicated guide to the selection questionnaire covers the current SQ format in full. This guide focuses on the PQQ concept and practical completion — the disciplines that apply whether the document is labelled a PQQ or an SQ.

What Does a Pre-Qualification Questionnaire Assess?

Financial Standing

Buyers assess financial standing to confirm your organisation can deliver the contract without risk of insolvency. They typically request two or three years of filed accounts and require annual turnover of at least double the annual contract value. Some PQQs also assess financial ratios against defined thresholds. If your financial standing falls short, a consortium arrangement — bidding with a financially stronger partner — can provide a route through. Our guide to government contracts for SMEs covers this in full.

Insurance Requirements

Most PQQs require evidence of public liability, professional indemnity and employers liability insurance at specified minimum levels. Check your coverage meets or exceeds the stated minimums before submitting. An inadequate insurance level is a mandatory fail on most PQQs — it disqualifies your submission regardless of everything else.

Relevant Experience

Buyers ask for two or three examples of comparable contracts delivered within the last three to five years. Strong responses name the client, describe the scope and scale, state the contract value and duration, and quantify outcomes with measurable statistics. Vague sector experience earns minimal marks. Specific, comparable, quantified case studies earn the highest scores and strongest shortlist positions. Our guide to writing case studies for tenders gives you the complete framework for building evidence that passes the experience assessment every time.

Policies and Compliance Documentation

PQQs typically ask suppliers to confirm they hold appropriate policies covering health and safety, quality management, environmental management, equality and diversity, data protection and modern slavery. Some require the policies themselves as attachments; others ask for confirmation and key details. Keep your policies current and signed before opportunities arise — a PQQ deadline will not wait for you to draft one. Our guide to being tender ready covers the full framework for keeping your compliance documentation submission-ready.

Accreditations and Certifications

ISO 9001, ISO 14001, Cyber Essentials, Constructionline and a range of sector-specific certifications appear regularly across public sector PQQs. Review which accreditations are most common in your target sectors and obtain them proactively — before you encounter a PQQ that requires them as a mandatory pass criterion.

Legal and Compliance Declarations

Every PQQ includes mandatory declarations covering your organisation’s legal status, legislative compliance and grounds for exclusion. Mandatory exclusion grounds include serious criminal convictions, tax evasion, fraud, corruption and modern slavery offences. Discretionary grounds include insolvency, professional misconduct and significant failures on previous public contracts. Complete these accurately and honestly. False declarations are grounds for immediate disqualification — and potentially debarment from future public procurement under the Procurement Act 2023. If your organisation has any relevant compliance history, seek specialist procurement legal advice before submitting.

How Pre-Qualification Questionnaires Are Assessed

Assessment runs in two stages. First, buyers check mandatory criteria — financial standing, insurance, legal declarations and policy requirements — on a pass/fail basis. A single mandatory failure excludes your submission, regardless of everything else. Where the PQQ includes scored quality questions, buyers then rank passing suppliers by quality score. The highest-scoring suppliers — up to the shortlist number — proceed to the full ITT. In competitive PQQs, the quality of your experience responses can be the deciding factor in whether you make the shortlist at all.

How to Complete a Pre-Qualification Questionnaire Successfully

Read every document before writing anything. Note every mandatory requirement, minimum threshold and compliance declaration. Identify any criterion your organisation doesn’t currently meet and decide whether you can close the gap before the deadline — or whether to decline the opportunity. Our guide to the bid no bid decision gives you the framework for making that call. Gather every required document before you start. Company accounts, insurance certificates, accreditation certificates and signed policies should all be assembled and checked for currency before you complete the first section. Documents discovered to be missing or outdated at submission stage create failures you cannot fix against a live deadline. Write experience responses to the highest possible standard. Use the full word count. Name specific clients, contracts, values and outcomes. Quantify every performance claim. Choose the most directly comparable examples available — mirroring the contract type, sector and scale of the opportunity. Our guide to quality tender responses applies here just as powerfully as it does to full ITT answers. Maintain a well-organised bid library. Current accounts, insurance certificates, accreditations, policies and standard experience responses — kept up to date between opportunities — make PQQ completion faster and stronger every time. Submit early. Portals close at the stated deadline to the second. Submit at least 24 hours before the deadline, confirm receipt and save the confirmation. Our tender submission checklist covers every pre-submission step.

Frequently Asked Questions About Pre-Qualification Questionnaires

What is a pre-qualification questionnaire?

A first-stage assessment document buyers use to check whether suppliers meet minimum eligibility criteria before inviting them to the full tender stage. It covers financial standing, experience, insurance, policies, accreditations and legal compliance. Pass and you’re shortlisted for the ITT. Fail and you’re out of the competition.

What is the difference between a PQQ and an ITT?

The PQQ is the eligibility filter — it determines which suppliers make the shortlist. The ITT is the full competitive stage — where quality responses are written, pricing is submitted and the contract is awarded. Our guide to ITT meaning and how it works covers the ITT stage in full.

What is the difference between a PQQ and a selection questionnaire?

They describe the same thing. PQQ is the older term; Selection Questionnaire (SQ) is the current standard under the Procurement Act 2023. Our guide to the selection questionnaire covers the current SQ format in full.

What financial information do I need for a PQQ?

Most PQQs require two or three years of filed company accounts — turnover figures, profit and loss statements and balance sheets. Buyers typically require annual turnover of at least double the annual contract value. Have your most recent accounts ready before monitoring for opportunities — outdated financials are a preventable compliance failure.

Can I fail a PQQ and still win the contract?

No. A PQQ failure excludes you from the competition entirely. You cannot proceed to the ITT or submit a quality response. Passing the PQQ is the gateway to competing — it doesn’t guarantee a win, but failing it makes winning impossible.

How do I improve my PQQ success rate?

Keep your policies, accreditations and insurance current at all times. Build strong, quantified case studies from every comparable contract you deliver. Apply a disciplined bid no bid check before every PQQ. Write experience responses to the highest standard — specific, quantified and directly comparable.
