Conditional contractor approval when documents are missing

A supplier can be commercially attractive while one part of its prequalification file is incomplete. The dangerous shortcut is to mark it “approved” without saying approved for what. A conditional procurement decision may allow a buyer to continue a tender or reserve capacity; it should not silently become permission for people to start work on site.

This guide sets out a practical decision record for a contractor whose required evidence is missing or still under review. It concerns the buyer's own process in Great Britain. It does not turn every document request into a statutory rule; legal duties, the contract and site-specific risks determine which gaps are critical.

Name the missing fact, not merely the missing file

Start with the proposed scope, legal entity, site, dates and work activities. Then ask what the absent item was meant to prove. Is the problem that a file was not uploaded, that no current policy exists, that the policyholder does not match the bidder, or that nobody has checked whether a qualified worker will do the work? Those are different issues and can need different responses.

HSE's Using contractors guidance asks a client to identify the job, select someone suitable, assess risk and coordinate the work. Evidence should be proportionate to the job. It is therefore more useful to describe a concrete gap, such as “no evidence that the named electrical supervisor is competent for this installation”, than to use a generic red status with no explanation.

Separate three possible decisions

Do not use “conditional approval” as a universal rule for every risk. If the missing evidence concerns a required legal authorisation, an unresolved insurance coverage issue or a safety-critical competence question, the relevant work must wait until an authorised person has resolved it. A buyer's software status cannot waive a statute, policy term or contractual condition.

Keep the work-start gate separate

Before mobilisation, recheck the condition against the actual delivering entity and activity. Has the required evidence arrived? Is it current through the relevant period? Has someone competent reviewed it? Does it address the work in the contract, not only a generic trade description? If the answer is no, keep the affected work on hold and escalate to the person authorised to decide what happens next.

For construction work, HSE's planning guidance explains why key arrangements must be made before the construction phase. A conditional commercial selection cannot substitute for the planning, coordination and information required for safe site work. The broader prequalification-to-mobilisation handover shows how to transfer a completed decision to the site team.

Make the exception visible and finite

Use an exception record with: supplier and entity; work package; missing item and reason; legal or contractual source if one applies; risk owner; permitted procurement activity; activities expressly blocked; evidence requested; deadline; reviewer; result; and date the condition was closed. A due date alone is weak if nobody owns the decision after the due date passes.

If the only issue is a rejected insurance document, the specific remediation guide gives a narrower path. If the issue is an insurance policy whose scope is unclear, use the initial insurance evidence check and seek broker or insurer clarification. Do not claim that a general conditional approval settles coverage.

When evaluating contractor prequalification software, ask whether it can represent a conditional procurement state and a separate start-work gate, keep the underlying evidence, notify the responsible reviewer and show the decision history. Ask for a live demonstration of those exact controls. This article does not assert that Complys currently automates them or determines whether a contractor is legally safe to appoint.

Primary sources and publication gate

• HSE — Using contractors: work definition, suitable contractor selection, risk and coordination.
• HSE — Planning for construction work: planning and appointments before the construction phase.
• HSE — Commercial clients under CDM 2015: client arrangements and capable appointments on construction projects.

Owner check before integration: Compare the whole live prequalification checklist, onboarding checklist and P4-005 handover. If one already provides this exact conditional procurement-versus-work-start decision in depth, merge these steps there. The three HSE sources support the risk and planning principles; the three-state table is an editorial operating model, not a legal classification created by HSE.
