About this episode

Jacob Austin discusses unlawful omission variations in UK construction and the rights of subcontractors.

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…
