Five Ways Contractors Hide Illegal Payment Clauses

Episode 140 of The Subcontractors Blueprint sees Jacob Austin expose five ways main contractors are disguising illegal payment clauses in bespoke subcontract amendments — nearly 30 years after pay when paid was banned under the Housing Grants, Construction and Regeneration Act 1996. Jacob maps the specific clause patterns to watch for, explains why the 2009 amendment to the Construction Act extended that prohibition to pay when certified arrangements, and shows how the Scheme for Construction Contracts protects subcontractors when unlawful provisions have already been signed. The core message: these clauses survive only because subcontractors don't read their contracts and don't challenge them.

KEY TAKEAWAYS

  • Why retention release clauses tied to main contract practical completion are void — and how to challenge them.
  • How contractors dress up "back to back" variation arrangements to avoid paying you for changes they won't recover themselves.
  • Why a floating payment due date linked to the main contract valuation cycle fails the Construction Act.
  • The one conditional payment clause that is still lawful — and why tight commercial management is your only real protection when it applies.
  • Why the Scheme for Construction Contracts is already on your side, even when the contractor's terms aren't.
  • Why challenging a non-compliant clause by email costs nothing — and why waiting until the money is gone costs everything.

BEST BITS

"So if you sign up to a non-compliant clause and never challenge it, you can guarantee the main contractor is going to use it against you."

"How many times do they actually 100% transfer the same scope from their contractor to your contract?"

"There are no legal technicalities after the fact that do a better job of managing your money than you getting your hands on it at the right time."

"If you don't know, you can't manage your position and you can't challenge it, so you always need to start by reading that subcontract."

"These kind of clauses have survived this long because subcontractors don't challenge them and quite often don't even appreciate that they're sat there in their subcontracts because they haven't read them."

"The law doesn't enforce itself, but you can enforce it."
