Williams v Roffey Brothers and Nicholls (Contractors) Ltd [1991] 1 QB 1 Court of Appeal

This was an action in debt for building work done pursuant to a promise made by the defendants whereby they undertook to pay more for this work than they had stipulated in the original contract. The defendant claimed that the promise to pay the extra money was unsupported by consideration, but the Court of Appeal disagreed; the defendants had received a real benefit in return for their promise to pay more.
