MWB Business Exchange Centres Ltd v Rock Advertising Ltd

Factual and Procedural Background

MWB Business Exchange Centres Ltd ("MWB") operated managed office space in central London. Rock Advertising Ltd ("Rock") provided marketing services and had occupied premises managed by MWB as licensee for seven to eight years. In August 2011, Rock expanded its business and entered into a written licence agreement for larger premises at an increased fee, commencing 1 November 2011. The licence fees were £3,500 per month (excluding VAT) for the first three months, increasing to £4,433.34 per month from February 2012.

Rock was unable to meet these financial commitments due to business underperformance and by late February 2012 had arrears exceeding £12,000. On 30 March 2012, MWB exercised its contractual right to lock Rock out and subsequently purported to terminate the licence effective 4 May 2012.

MWB claimed arrears of licence fees and damages, while Rock counterclaimed for loss and damage resulting from alleged wrongful exclusion. Rock asserted that on 27 February 2012 an oral agreement was made with MWB's credit controller to reschedule licence fee payments from February to October 2012, involving lower initial payments followed by higher payments to clear arrears by year-end. Rock paid £3,500 on that date as the first instalment under this schedule. Alternatively, Rock argued that MWB was estopped from denying the variation due to acceptance of this payment.

MWB denied any agreement was reached on 27 February and relied on a subsequent email on 29 February 2012 insisting on minimum monthly payments of £5,320. The County Court judge found that an oral agreement was made and that MWB's representative had ostensible authority to agree it but soon treated it as a proposal after internal rejection, leading to the 29 February email. The judge held that Rock's promise to pay under the revised schedule constituted good consideration, rejecting MWB's argument to the contrary. However, the judge found that clause 7.6 of the original licence agreement, requiring written and signed variations, precluded oral variation and dismissed Rock's estoppel argument.

MWB was awarded judgment on its claim and Rock appealed on two grounds: first, that clause 7.6 did not preclude oral variation of the contract including the clause itself, and second, that the estoppel argument was wrongly dismissed. MWB contended the judge was correct but erred in finding good consideration for the oral variation.

Legal Issues Presented

1. Whether clause 7.6 precluded any variation of the agreement other than one in writing and signed by both parties;
2. Whether Rock provided any good consideration for the oral variation;
3. Whether the judge ought to have held that MWB was estopped from enforcing its rights under the original agreement.

Arguments of the Parties

Appellant's Arguments

• The judge was wrong to hold clause 7.6 precluded oral variation; parties could vary the contract orally or otherwise, including clause 7.6.
• The oral agreement made on 27 February 2012 was binding on MWB.
• The estoppel argument should have succeeded because Rock suffered detriment by paying £3,500, making it unconscionable for MWB to enforce the original terms.

Appellee's Arguments

• The judge was correct to dismiss Rock's claim.
• The oral variation lacked consideration because payment of an existing debt by instalments does not constitute good consideration.
• Clause 7.6 required written and signed variations to be effective.
• Estoppel did not apply as Rock did not suffer detriment and MWB did not waive its rights.

Court's Reasoning and Analysis

The court first addressed the effect of clause 7.6, an anti-oral variation clause requiring written and signed variations. After considering conflicting authorities, including United Bank Ltd v Asif and World Online Telecom v I-Way Ltd, the court preferred the reasoning in World Online Telecom and the subsequent authoritative decision in Globe Motors. The court emphasized the principle of party autonomy, holding that such clauses do not preclude oral variations if the parties agree to them.

The judge’s factual finding that an oral variation agreement was reached on 27 February 2012, and that MWB’s representative had ostensible authority, was upheld as reasonable on the evidence.

Turning to consideration, the court analyzed the traditional rule from Foakes v Beer that payment of an existing debt is not good consideration for a promise to accept less. However, the court distinguished this case on the facts, finding that the oral variation conferred a practical commercial benefit on MWB beyond mere accommodation of Rock’s financial difficulties. This included immediate partial payment of arrears and retention of Rock as a tenant, avoiding the loss associated with vacant premises ("avoiding a void").

The court relied on the principle from Williams v Roffey Bros that practical benefit can constitute good consideration, and rejected MWB’s submission that Foakes v Beer and In re Selectmove precluded such a finding here. The court concluded the oral variation was supported by sufficient consideration and therefore binding.

On estoppel, the court noted the doctrine requires a representation that strict rights will not be enforced, reliance, and inequity in enforcing those rights. The court found no detriment to Rock beyond payment of sums it was contractually obliged to pay, and that MWB had given reasonable notice of reverting to original terms shortly after the oral agreement. Therefore, it was not inequitable for MWB to enforce the original agreement. The court also held that waiver and proprietary estoppel did not add to the promissory estoppel argument and were similarly unavailing.

Holding and Implications

The court ALLOWED the appeal on the basis that clause 7.6 did not preclude oral variation of the licence agreement and that the oral variation agreement reached on 27 February 2012 was supported by good consideration and thus binding on the parties.

The estoppel argument was not upheld, as it was not inequitable for MWB to enforce its original rights given the circumstances. The court’s decision directly affects the parties by recognizing the oral variation agreement as enforceable, overturning the previous judgment. No new precedent was established beyond confirming the applicability of existing principles of party autonomy and practical benefit as consideration in contract variations.
