How Do We Stop Letting Subcontractors Start on Site Before Their Insurance and Paperwork Are In?

Main contractors chase subcontractor insurance, accreditations and bank details by email. We build a supplier portal that collects, checks and tracks expiry.

Quick answer — TL;DR

Subcontractor paperwork falls behind because it is collected by email into a shared folder and nobody owns the expiry dates. We build a subcontractor portal where each firm uploads its insurances, accreditations and company details once, dates are read and checked, expiries are chased automatically, and site and commercial teams see a simple status before an order is placed or a gang arrives.

Monday morning, a new gang at the gate

A dryliner your QS placed an order with last week turns up on site. The site manager asks the office whether they are approved. Someone searches the shared drive and finds a public liability certificate from two years ago, no employer's liability certificate and a bank details form in an email thread. The dryliner says they sent everything to the buyer. The buyer is on holiday.

Multiply that by every trade on every job, and a surprising part of your commercial and admin time goes on chasing, filing and re-checking documents for firms you have used for years.

Why the folder never stays current

Documents are collected once, at the start of a relationship, and then left. Insurances renew every year on different dates. Accreditation schemes renew on their own cycles. Company details change. Nobody gets a reminder, so the folder quietly goes stale.

  • Documents arrive as email attachments to whoever asked for them.
  • Expiry dates are not recorded anywhere except on the certificate itself.
  • Site teams cannot see approval status without phoning the office.
  • The same firm is asked for the same documents by different buyers.
  • Bank detail changes arrive by email with no call-back check, which is how payment fraud gets in.

What the gaps cost

Orders get placed with firms whose cover has lapsed, and nobody knows until a claim or an audit. Clients and frameworks ask for evidence of your supply chain checks, and building that pack by hand takes days. Admin staff spend hours each week on chasing emails. What your policy requires from each subcontractor is your decision, and your insurers and advisers set it; the problem we fix is knowing, at any moment, who meets it.

The subcontractor portal we build

  1. Each subcontractor gets a secure link to their own record, where they upload insurance certificates, accreditations and company details once.
  2. Documents are read on upload: insurer, policy type, cover level and expiry are extracted and shown back to the subcontractor to confirm.
  3. Your requirements per trade are set as rules, for example the insurances and levels your policy asks for a groundworker compared with a decorator.
  4. Each firm shows a status: approved, missing items, or expiring soon, with the reason.
  5. Reminders go to the subcontractor before expiry, then escalate to your buyer if nothing arrives.
  6. Bank detail changes are held until a named person confirms them by phone on a number already on file.
  7. Status is visible when an order is raised in your job costing system and on the site manager's phone at the gate.

A supply chain you can see

Subcontractors keep their own documents current because the portal asks them to, not your admin team. Buyers see approval status when they place an order. Site managers see it at the gate. When a client or framework asks for supply chain evidence, it is a report rather than a week of searching. And bank detail changes stop being a risk hidden in an inbox.

It also changes the conversation with good subcontractors. Firms that keep their records current are easy to order from, and your buyers can see at a glance which firms on a tender list are ready to start. The ones that never answer a reminder show themselves early, before they are on your programme rather than after.

Signs your subcontractor records need this

  • Insurance certificates are filed in a shared drive by whoever received them.
  • You find out cover has lapsed after the event.
  • Site teams phone the office to ask if a firm is approved.
  • Subcontractors complain they are asked for the same documents repeatedly.
  • Bank detail changes are accepted by email.

FAQ

Frequently asked questions

The questions readers ask us after this guide.

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

Does it replace our accreditation scheme membership?

No. Schemes like Constructionline or CHAS stay as they are. We record each firm's status and expiry alongside your own requirements.

Will subcontractors bother to use it?

Uploading once is less work for them than answering the same email from three buyers. A firm that does not respond is flagged to your buyer.

Can it read certificates from any insurer?

It reads common layouts and asks a person to check anything it is unsure of. Nothing is marked approved on an unchecked read.

Does it decide whether a firm is approved?

It applies the rules you set. What those rules are is your decision with your insurers and advisers.

What affects the cost?

The number of subcontractors, how many trades have different rules, and the systems we connect to for orders and payments.
