The one who won the contract and subcontracts it all

You signed and someone else does the work. As far as the site is concerned there is still one name on the contract, and it is yours.

Updated on 13/08/2026

You win the maintenance contract for twelve sites and you do not have twelve teams: you have arrangements with local firms who deliver it. **The client did not contract those firms, they contracted you**, so anything they ask, they ask in your name. This position carries a very specific trap: the paperwork you will be required to produce is not yours, and you answer for it anyway.

What you answer for, depending on who is looking

**Your insurer****Who actually did the work****Whoever can prove it**

Important

**You are the position with the worst information about what actually happens, and the one that has to answer about it fastest.** Whoever is on site sees it; the site lives with it; you find out from a report that arrives on the 5th of the following month, if it arrives. Closing that gap is not about control: it is the only thing that lets you answer without phoning someone who may not pick up.

What to set up before the first job

  1. 1

    What each subcontractor must provide, written and up front

    And no less than the site requires of you, or you pay the difference.

  2. 2

    How their paperwork arrives without chasing

    It is third-party documentation, so it has to be requested and chased.

  3. 3

    What evidence each job leaves behind

    The report, who did it and when. If nothing remains, for answering purposes it did not happen.

  4. 4

    What happens if a subcontractor subcontracts

    If you do not decide it, they will.

Watch out

The classic mistake here is **requiring less of the subcontractor than the client requires of you**, usually because requiring everything would make them dearer or slower. That gap does not disappear: it sits on your balance sheet as a hole that opens on its own the day someone asks. And it is usually discovered at the worst possible moment — after something has happened and the papers of whoever was there have to be produced.

Worth knowing

What liability the party who subcontracts assumes towards the client and the authorities, and what verification duties they carry over their suppliers, **depends on the contract and the sector, and is settled by your adviser**. Here we cover the part fully within your control: what you require, how it reaches you, and what is recorded about each job.

Can I require of my subcontractor exactly what is required of me?

It is advisable. The gap between what is asked of you and what you ask is your risk.

Must I show my supplier's papers to the client?

It depends on the contract, but being able to is worth it before they ask.

What if the subcontractor sends nothing?

That is the normal scenario. Which is why the request has to chase on its own.

A real case

The situation

The client asks for the documentation of the firm that did the work, which is not yours.

What you do

  1. Keeps each subcontractor's file alongside the contract it serves

What you get

It is handed over without phoning anyone or waiting for a reply.

The situation

Each subcontractor sends their papers whenever they remember, in whatever format.

What you do

  1. Requests specific documents and chases until they arrive

What you get

What arrives is comparable across all twelve firms.

The situation

The subcontractor is asked for less than the client asks of you.

What you do

  1. Writes down what is required and checks it is complete

What you get

The gap is visible before anyone asks about it.

The situation

A site's job report arrives the following month, or not at all.

What you do

  1. Captures the evidence of the work when and where it happens

What you get

The month closes on what happened rather than what is remembered.

The situation

A subcontractor subcontracts in turn and you find out afterwards.

What you do

  1. Records which firms are authorised under each contract

What you get

The chain stops growing without anyone knowing.

The situation

Twelve sites, twelve firms and no overall view of who is current.

What you do

  1. Shows the status of every supplier at once

What you get

You act on the two that are failing instead of all twelve.
