Educational guides on how workplace documents fit together — which document is typically completed before another, what is used alongside it and what follows. Connected to workplace forms, checklists and registers. Informational only — not legal advice; employers remain responsible for required documents and compliance.
What a subcontractor approval workflow is
A subcontractor approval workflow is the chain of documents a main contractor or principal uses to decide whether a subcontractor is suitable for a package of work — a pre-qualification questionnaire, evidence such as insurance and competence, a review of method statements and risk assessments, an agreement checklist, and a record of the approval.
This page is an educational overview of how those documents connect within a contracting chain. It is not an official template and not legal advice — the main contractor decides what approval requires.
Why these documents connect
Subcontractor documents connect because work flows down a chain: the main contractor takes on duties towards the principal and then needs assurance that each subcontractor can deliver its package safely. Pre-qualification and evidence gate the agreement, and the agreement and RAMS gate mobilisation.
Linking them avoids the common gap where a subcontractor is engaged on price alone, with no review of competence, insurance or method, and no record of the decision.
The typical sequence
- Required before: a pre-qualification questionnaire from the subcontractor.
- Required before: insurance, competence and reference evidence reviewed.
- Used with: a review of the subcontractor’s method statements and risk assessments.
- Used with: a subcontractor agreement checklist setting out scope and conditions.
- Completed after: the subcontractor recorded as approved for the package.
- Completed after: mobilisation and induction once approval is in place.
Who owns each step
- A main contractor’s commercial or procurement lead owns pre-qualification.
- A safety or technical reviewer owns the RAMS and competence review.
- A project manager owns the agreement and approval decision.
- The main contractor remains responsible for its own duties and for compliance.
Common mistakes
- Engaging on price without checking competence or insurance.
- Approving the company but not the specific people on site.
- No clear scope, so the subcontractor works beyond what was agreed.
- Letting evidence lapse during a long project.
Records and retention (high level)
Subcontractor approval records are generally kept by the main contractor for the duration of the works and a period afterwards, in line with its obligations and data-protection duties.
This page does not state a required period — confirm retention with the applicable law and the official authority.
Sharing the workflow as a PDF
Pre-qualification, evidence and the agreement are commonly completed and stored as PDFs so they can be held together against the subcontractor record. Exporting to PDF supports the record; it does not make the approval official or guarantee compliance.
Employer notes
- Decide what approval depends on before engaging a subcontractor.
- Review the actual evidence and RAMS, not just price.
- Set a clear scope and conditions for the package.
- Keep evidence current through long projects.
Subcontractor notes
- Provide the evidence the main contractor requests.
- Keep insurance and competence current through the project.
- Stay within the package scope you were approved for.
- Do not start before approval is recorded.
Country considerations
How subcontractors are assessed and what duties flow down a contracting chain vary by country and by sector, and the official authority differs. This page is general and high-level — not a statement of any country’s law and not a guarantee of validity.
Confirm current requirements with the official authority for your country and a qualified professional.
Who is responsible
The main contractor or principal is responsible for its own duties in the contracting chain, for what approval requires, and for compliance. This page is an educational overview with a template example; it does not approve anyone and does not transfer responsibility.
