MWB Business Exchange Centres Ltd v Rock Advertising Ltd [2016] is a pivotal Court of Appeal authority exploring the extension of the practical-benefit doctrine to the part payment of a debt. The ruling suggests that preserving an underlying commercial relationship — such as avoiding a void in property occupancy — may constitute sufficient consideration to support a downward variation of a contract.

Facts of the Case

Rock Advertising (the defendant) occupied managed office premises in London under a licence agreement with MWB (the claimant). Rock fell into arrears of approximately £12,000. The parties reached an oral agreement to reschedule the payments, whereby Rock would pay less in the early months and more towards the end of the year to clear the debt. Rock made an initial payment of £3,500 in accordance with this new schedule. However, MWB subsequently locked Rock out of the premises and sued for the original arrears, arguing the rescheduling agreement was not legally binding because it lacked consideration.

Legal Issues

The primary issue was whether the agreement to reschedule payments was supported by consideration. Under the long-standing rule in Foakes v Beer, part payment of a debt is generally not sufficient consideration because the debtor is only performing an existing legal obligation. The court had to determine if the “practical benefit” rule established in Williams v Roffey Bros (which applies to promises to pay more for services) could be extended to “downward” variations where a creditor agrees to accept less or deferred payment.

Judgement

The Court of Appeal ruled in favour of Rock Advertising, holding that the rescheduling agreement was supported by consideration. The court reasoned that MWB received practical benefits beyond the mere receipt of money:

  • Avoiding a vacancy: by retaining Rock as a licensee, MWB ensured the property would not stand empty, which would have resulted in further loss to the company.
  • Immediate payment: MWB recovered some arrears immediately and gained an improved prospect of recovering the full amount over time.

The court concluded that “avoiding a void” was an identifiable commercial advantage that constituted sufficient consideration in law.

Note: the Supreme Court later heard an appeal in this case ([2018] UKSC 24). It allowed the appeal on the grounds of a “No Oral Variation” clause in the contract, meaning it did not have to decide the consideration point. The Court did, however, note that the issue was “difficult” and “ripe for re-examination” by an enlarged panel in the future.

Authority and Significance

  • Narrowing Foakes v Beer: the decision suggests that Foakes v Beer may now be confined to cases where the creditor obtains no benefit other than the promise to pay the debt itself.
  • Unified practical benefit: the ruling implies there is no “coherent distinction” between agreements to pay more for work and agreements to accept less for a debt; if a practical benefit exists, consideration is satisfied.
  • Commercial reality: the decision reflects a judicial willingness to mirror the practicalities of business life, where retaining a defaulting tenant is often more valuable than having a vacant property and a right to sue.
  • Supreme Court scepticism: despite the Court of Appeal ruling, the Supreme Court’s later comments indicate that extending Williams v Roffey to debts remains controversial and requires a higher-level review to reconcile it with House of Lords precedent.
