Termination Hiding Inside a Variation

Episode 145 of The Subcontractors Blueprint sees Jacob Austin examine one of the most common and costly manoeuvres in UK construction — the unlawful omission variation. When a main contractor strips scope from a subcontract and hands it to a competitor, the variation clause is almost never broad enough to make that lawful. This episode breaks down the implied contractual right that protects subcontractors — established in Abbey Development v PP Brickwork — and sets out exactly how to identify a partial termination dressed as a variation instruction, serve the right notices, and claim the profit and overhead you've lost.    

KEY TAKEAWAYS

- Why the variation clause is almost never broad enough to let a main contractor omit your work and hand it to a competitor

- The Abbey Development v PP Brickwork case and the implied right it gives every subcontractor to complete work they've been awarded

- Five telltale signs that an omission instruction is actually a partial termination in disguise

- Why silence on the day the instruction arrives could cost you the entire claim even if your legal argument is solid

- How to quantify the loss correctly: it's not just the omitted work, it's the profit and overhead you'd budgeted against it

- When the scale of omissions crosses into repudiation — and why that opens a much larger claim

BEST BITS

"The variation clause is there for adjusting the scope. It's not a mechanism for the main contractor to reassign your work to a competitor while keeping you on site for everything else."

"You take on the obligation, you get the right to finish what you started."

"The work hasn't disappeared from the site, it's just disappeared from your order."

"The instruction arrives on the contractor's standard official looking variation form it doesn't make it valid."

"Compliance without any protest at all will be read as acceptance by your contractor."

"Even a valid claim that misses the deadline is one that you've lost so more than anything be sure to submit on time."
