The compliance work most contractors do twice

A typical subbie engagement requires: insurance evidence, RAMS, method statement, training records, modern slavery statement, sometimes ConstructionLine or SafeContractor evidence, and various site-specific paperwork.

Most contractors collect this paperwork once when the subbie is onboarded. Then they collect it again when it expires. Then again when a new client asks. Then again when a tender requires it. The same documents, requested four or five times a year.

The cost is hours of admin time, not the cost of the documents themselves. For a company with 30 active subbies, that's typically a junior PM tied up for a whole Monday morning, every week.

Where AI fits in the subbie pipeline

AI does three things well in this workflow. It extracts data from supplier documents into a structured format (so the next request is already filled in). It tracks expiries automatically and chases the subbie before the document lapses. And it assembles the evidence pack for any tender or audit from the documents on file.

None of this requires the subbie to do anything different. The change is on your side: less manual collection, less chasing, less last-minute scramble before a tender deadline.

What good subcontractor automation looks like

The system holds a current, verifiable record for every active subbie: insurance status, training, RAMS, accreditations. It sees the expiry dates and chases automatically.

When a tender lands and asks for "evidence of your subbie compliance for the last twelve months," the response is an automatically assembled pack, produced in minutes instead of hours.

When an audit happens, the auditor is given the same pack. The audit takes one morning instead of two days.

What it costs vs. what it saves

Setting up a subcontractor compliance workflow well typically costs £5–15k, depending on the size of the subbie pool.

For a company with 30 active subbies, the time savings are usually 4–6 hours a week of admin or junior PM time. That's £8–12k a year, fully loaded, just on time.

The bigger value is the tenders won because the compliance pack was ready and the audit findings that didn't happen. Those don't show up in a payback calculation but they're what makes this workflow strategic, not just tactical.
