What Is a Selection Questionnaire (SQ / PQQ)?
A Selection Questionnaire (SQ) — still often called a PQQ (Pre-Qualification Questionnaire) in supplier shorthand — is the information contracting authorities use to check whether suppliers meet conditions of participation before or alongside scored tender evaluation. It typically covers exclusion grounds, economic and financial standing, technical ability and mandatory policies. Failing an SQ gate ends the bid regardless of how strong your written quality answers are. This guide explains SQs for UK public tenders in 2026 and how to prepare a reusable evidence pack.
Put this into practice
SQ failures are preventable with early monitoring and gate checks. TenderLedger helps you spot mandatory requirements before you invest in full drafting.
Why this matters commercially
Pass/fail selection is where many SMEs exit — often on paperwork, not capability.
Reusable SQ evidence shortens every future bid.
Financial standing tests can surprise fast-growing firms.
Exclusion and debarment questions need honest, complete answers.
SQ and award-stage answers must stay consistent.
How suppliers usually do this manually
Starting SQ the night before the deadline from scratch.
Different people answering financial vs technical sections without reconciliation.
Uploading expired insurance certificates.
Treating PQQ as optional because ‘we know the buyer’.
No central store of policies and certificates.
Signals worth tracking
Conditions of participation listed in the notice or SQ pack.
Turnover multiples, insurance levels, and certification requirements.
Requests for case studies with named referees and contract values.
Self-declarations on exclusions, modern slavery, and conflicts.
Whether selection is a separate stage or submitted with the tender.
Common mistakes to avoid
Leaving blanks instead of explaining ‘not applicable’ where allowed.
Over-claiming certifications you cannot evidence.
Using group turnover without clarifying bidding entity.
Ignoring consortium/SQ rules when bidding jointly.
Updating award-stage stories that contradict SQ declarations.
How TenderLedger supports this workflow
Summaries flag likely participation gates from notices and packs.
Qualification scoring encourages SQ readiness checks before writing.
Buyer patterns show typical gate stringency in your sector.
Earlier alerts give time to renew certificates.
Pursuit records keep SQ outcomes for learning.
Example in practice
A scale-up failed three SQs on cyber certification, paused bidding for six weeks to obtain Cyber Essentials, then passed subsequent gates.
A regional contractor created a live ‘SQ vault’ in SharePoint; average SQ completion time fell from three days to four hours.
Practical workflow
Build a standing SQ pack: policies, accounts, insurance, accreditations, case studies, org chart.
Quarterly refresh of expiry-dated documents.
On each bid: map SQ questions to pack artefacts within 24 hours.
Legal review of exclusion/debarment answers when anything is non-standard.
Version-control what you submitted on each portal.

About this data
TenderLedger aggregates UK public procurement signals from official sources including Find a Tender (FTS) and Contracts Finder. We combine notice metadata, contracting authorities, and award history into a consistent opportunity view for suppliers.
For these pages, we structure insights using procurement patterns commonly visible in award notices, framework call-offs, and DPS activity. The examples below are designed to mirror how supplier teams qualify bids day-to-day.

FAQs
Is SQ the same as PQQ?
In practice suppliers often use the terms interchangeably for selection/pre-qualification information. Follow the labels and forms in the live procurement documents.
Is the SQ scored?
Many selection questions are pass/fail conditions of participation. Some technical ability evidence may be assessed; award criteria scoring usually sits in the tender response proper.
What if I fail one SQ question?
A failed mandatory gate typically excludes you. Clarify via the portal if the requirement is ambiguous — do not assume a workaround.
Do frameworks use SQs?
Yes — joining frameworks/DPS usually involves selection-style information, then later mini-competition responses.
How early should I prepare SQ evidence?
Continuously. Certificates and accounts are slow to obtain; do not wait for a live notice.
