For small UK principal contractors

Can this subbie start on site Monday?

You already chase insurance, CSCS and RAMS on WhatsApp. SubbiePack is one list per firm: who is in date, who is expiring, who is blocked from site — with the files you were sent.

Monday at the gate. The list is for this moment.

The Monday problem

The files are in the chat. The answer is not.

Sunday night you still send the same message: have you got public liability, CSCS and RAMS? Photos come back mixed with jokes, invoices and a van that will not start. Monday morning you still cannot say who can start.

SubbiePack does not replace the relationship. It replaces the chase with a list your office can open on a phone.

The files live in a pile and a phone. The list is meant to replace the chase.

What you keep on file

Four document types. Three of them block the gate.

Each subbie has one current file per type, with an expiry you type (DD/MM/YYYY). PDF or photo. We record what they uploaded and the date they typed. We do not say the file is genuine.

File To be in date
Public liability insurance Required
Employers’ liability Optional — not every sole trader has it
CSCS Required
RAMS Required

Example — J. Hughes Joinery

Current files

One current file each. Typed expiry, not a check with anyone else.

  • Public liability in date

    Expires 14/03/2027 · PL-hughes.pdf

  • Employers’ liability not held

    Optional. Sole trader, no employees.

  • CSCS in date

    Expires 02/11/2026 · card photo

  • RAMS in date

    Expires 30/06/2026 · RAMS-joinery.pdf

How the list works

Blocked, expiring, or in date — in that order

The homepage when you are paid is a mobile list, not a spreadsheet. Tap through to the subbie and the file.

Blocked from site blocked

A required file is missing or the typed expiry has passed. Public liability, CSCS and RAMS are required. They should not start until that is put right.

Expiring expiring

Still in date, but inside your reminder window — 30, 14 or 7 days. Chase now, not on the morning they are due on site.

In date in date

Required files are present and the dates you typed are still ahead. Employers’ liability does not block a sole trader who does not have it.

Ask the subbie

Send a link. They upload from a phone.

Generate a single-use link for one subbie and one document type. It lasts 7 days. They open it, send a PDF or photo, type the expiry. They do not need an account.

You see waiting on them versus they uploaded. That is the WhatsApp chase, without the chat.

Public liability insurance

Northside Contracts asked K. Patel Electrical to send this file from a phone. No account needed.

Expiry date (DD/MM/YYYY)
31/12/2026
PDF or photo
Choose file

We record the file and the expiry you type. We do not check whether the file is genuine.

Reminders

The office gets the email. Not a panic text.

When a file hits 30, 14 or 7 days, and on the day it expires, SubbiePack emails the firm. You set those windows in settings.

The copy is plain UK. No “certificate invalid”. There is no WhatsApp API in version one — that would be a promise we could not keep.

Example reminder — fictional

To office@example-firm.test

Subject Northside Brickwork — public liability in 14 days

Public liability for Northside Brickwork is due on 18/09/2026. Open the list if you want the file they already sent, or send them a new upload link.

Logged on the firm. Not sent to the subbie.

Sites and a pack

Who can start on that job, and a ZIP to send on

A site is a name and an optional address line. Assign the people on that job. The site view is who can start (all required files in date) versus who cannot.

The pack is a ZIP of current in-date files for that site. For sending on. It is not a certificate, and we do not issue one.

Example site — fictional

Hart Lane extension

Who can start, and a pack of current in-date files. The pack is not a certificate.

One firm

£29 a month. An extra office login is included.

Your login only sees your subcontractors. There is no public directory. The owner can invite one office or site manager by email — same data, no extra bill. The owner can revoke.

Without a subscription you cannot add subcontractors. Cancel in the Stripe customer portal when you want. Status changes when Stripe confirms it, not because a success page loaded.

  • GDPR export (JSON/ZIP) and delete this firm
  • Activity log: who added, uploaded, packed, or was reminded
  • Name, trade, phone, optional work email — not NI numbers, dates of birth or home addresses
