Subcontractor compliance management: the complete UK guide

The subcontractor readiness pack

A site-ready pack is a defined set of live, in-date documents that prove a subcontractor is safe, insured and legally entitled to work. The exact list depends on the trade and the principal contractor, but the core is remarkably consistent across UK construction and field services.

Building a live readiness record, not a folder graveyard

The classic failure is a well-meaning shared drive that grows into a graveyard of expired PDFs. The fix is to model each subcontractor as a record with typed documents, expiry dates and owners, so the system tells you when something's lapsed rather than the site manager finding out at the gate.

Handling the pre-start check like a pro

Before a subcontractor steps on site, a good pre-start check confirms every document is present, in date and matches the trade being carried out. Credbase turns this into a single link the site manager can open on a phone: green ticks, red flags, done.

Renewals, the rhythm that keeps you audit-ready

1. 60 days out: friendly heads-up to the subcontractor.
2. 30 days out: formal renewal request with an upload link.
3. 14 days out: internal escalation flag.
4. 0 days: subcontractor auto-flagged as not site-ready.
5. Post-renewal: file the new document, old version archived.

Sharing evidence with the principal contractor

Half the value of a well-run subcontractor record is being able to hand a principal contractor a live evidence pack in one click. Credbase generates a share link that reads from the same live record, always current, revocable and stamped with your brand.

What changes as your book grows

Ten subcontractors: a checklist works. Fifty: you need automatic reminders and per-trade packs. Two hundred and up: you need dashboards, per-project readiness views and the ability to answer a client's compliance question in under a minute. All of this is native in Credbase.
