The Hidden Dangers Buried in Your Subcontract

Episode 141 of The Subcontractors Blueprint sees Jacob Austin deliver a blunt commercial warning to every subcontractor in the UK who has ever signed a subcontract without reading it in full. Covering ten hidden dangers regularly buried in subcontracts by main contractors — from time bars and termination for convenience to back-to-back obligations and retention traps — this episode exposes the clauses that look routine on the surface but carry a sting that only surfaces when something has gone wrong on site. Jacob's message is direct: subcontract review isn't admin, it's the difference between protecting your margin and losing money you'll never get back.

KEY TAKEAWAYS

  • Why the clock on a time bar starts the day the event happens — not when you raise it in your next application.
  • How termination for convenience lets a main contractor walk away owing you what you spent, not what you were contracted to earn.
  • The one step in the day work procedure that, if missed, gives the contractor contractual grounds to reject your sheet outright — not reduce it.
  • Why agreeing back to back with a contract you haven't read means accepting obligations you don't even know you have.
  • How a final account time bar can wipe out months of built-up entitlement before anyone on site notices the deadline has passed.
  • Why "actual and proven losses" in a delay damages clause is far more dangerous than any fixed LED rate.

BEST BITS

"You've signed it. That's not them offering you a defence. It's a door closing in your face."

"Every pound that you earn, every pound that you lose flows from that document."

"The countdown on a time bar starts when the event occurs, not when you get around to raising it."

"Your subcontract isn't a formality to be dealt with after you've mobilised. It's a document that sets out your entire commercial relationship with the contractor on that project."

"If the subcontract says you're liable for the main contractor's losses, there's no cap."

"If you forget about it, you're probably forgetting some profit along with it."
