Can Consumer Contracts Be Frustrated When Supply or Prices Change?
In modern consumer markets, prices, supply chains, and the availability of goods and services can change rapidly. A product that was readily available when a consumer entered into a contract may later become difficult to obtain, while the cost of supplying that product may increase substantially.
This raises an important legal question: can a consumer contract be frustrated simply because the price has increased or the goods have become more difficult to obtain?
Under English contract law, the doctrine of frustration of contract may discharge parties from their contractual obligations in certain exceptional circumstances. However, frustration is a narrow doctrine and does not normally apply merely because performance has become more expensive, inconvenient, or commercially difficult.
What Is Frustration of Contract?
Frustration occurs where, after a contract has been formed, an unforeseen event occurs without the fault of either party and fundamentally changes the nature of the contractual obligations.
The doctrine may apply where an unexpected event
makes contractual performance impossible;
makes performance illegal;
prevents the agreed purpose of the contract from being achieved; or
fundamentally transforms the obligation into something substantially different from what the parties originally agreed to.
The courts have repeatedly emphasized that frustration is not intended to provide a general escape from a contract simply because circumstances have become less favorable.
Taylor v Caldwell: The Foundation of the Doctrine
One of the leading authorities on frustration is Taylor v. Caldwell (1863).
The parties had agreed to hire a music hall for a series of events. Before the events could take place, the hall was destroyed by fire.
The court held that the continued existence of the music hall was an implied condition of the contract. Since the premises no longer existed, performance had become impossible, and the contract was therefore discharged.
The case established an important principle: where the continued existence of a particular thing is fundamental to contractual performance, its destruction may frustrate the contract.
Does an Increase in Price Frustrate a Consumer Contract?
Ordinarily, no.
A significant increase in the cost of goods or services will not, by itself, frustrate a contract.
For example, suppose a consumer purchases a laptop for £1,000. Before delivery, the seller discovers that production costs have increased and that obtaining the same laptop now costs £1,500.
The seller will generally remain bound by the original agreement. The increase in cost represents a commercial risk rather than frustration of the contract.
Allowing every substantial price increase to frustrate a contract would undermine contractual certainty. Businesses routinely enter into contracts knowing that market conditions, supply costs, labor costs, and other commercial factors can change.
Davis Contractors Ltd v Fareham UDC
The principle can be seen in Davis Contractors Ltd v Fareham UDC (1956).
A building contract took considerably longer and became more expensive to perform because of unexpected difficulties. The contractor argued that the contract had been frustrated.
The House of Lords rejected that argument.
The court emphasized that frustration requires more than an increase in expense or difficulty. The question is whether the circumstances have fundamentally changed the nature of the contractual obligation.
This remains an important principle when considering whether changes in supply costs can discharge contractual obligations.
What If the Goods Become Difficult to Obtain?
The position is similar where goods become scarce or more expensive to source.
In Tsakiroglou & Co Ltd v Noblee Thorl GmbH (1962), the usual route for transporting goods became unavailable because of the closure of the Suez Canal. An alternative route was available, although it involved greater expense and delay.
The House of Lords held that the contract had not been frustrated.
The case demonstrates that increased expense, delay, or difficulty will not necessarily amount to frustration where performance remains possible.
For consumer contracts, this means that a seller will generally not be able to avoid its obligations simply because obtaining the goods has become more expensive or inconvenient.
When Could Supply Problems Actually Frustrate a Contract?
There may, however, be exceptional circumstances where a supply problem goes beyond ordinary commercial difficulty.
For example, frustration may become relevant where an unforeseen event
makes performance legally prohibited;
destroys the essential subject matter of the contract;
makes performance objectively impossible;
removes the fundamental purpose of the agreement; or
creates circumstances so radically different that performance would amount to something fundamentally different from what was originally agreed.
A relevant authority is Metropolitan Water Board v Dick, Kerr & Co Ltd (1918).
During the First World War, government action prevented a contractor from continuing work for an indefinite period. The circumstances went considerably beyond an ordinary increase in cost or difficulty and fundamentally affected the contractual obligations.
The case illustrates why the courts examine the nature and effect of the intervening event, rather than simply asking whether performance has become more expensive.
Consumer Contracts and the Consumer Rights Act 2015
The position can be particularly important in consumer transactions because consumers may have statutory rights in addition to their contractual rights.
The Consumer Rights Act 2015 provides important protections concerning contracts for goods, digital content, and services.
Depending on the nature of the transaction, consumers may have rights relating to matters such as:
satisfactory quality;
fitness for purpose;
conformity with the contract;
reasonable care and skill;
delivery; and
remedies where contractual or statutory requirements are not satisfied.
A business cannot necessarily rely on changing market conditions as a means of avoiding statutory consumer protections.
Accordingly, the doctrine of frustration should not be treated as a general mechanism allowing a business to cancel a consumer contract whenever the transaction becomes commercially unattractive.
Commercial Risk vs Frustration
The central distinction is between ordinary commercial risk and a genuinely frustrating event.
Businesses commonly face fluctuations in:
raw material prices;
transportation costs;
energy costs;
labour costs;
exchange rates;
product availability; and
supplier prices.
These risks will ordinarily remain part of the commercial bargain unless the contract itself provides otherwise.
If a seller could automatically terminate a contract whenever its costs increased, contractual commitments would become uncertain and consumers would have significantly less protection.
The courts therefore set a relatively high threshold before concluding that a contract has been frustrated.
What About Contracts With Price-Adjustment Clauses?
The wording of the contract is also important.
Some consumer or commercial agreements may contain clauses dealing specifically with changes in price, supply, taxation, delivery, or other market conditions.
Such provisions may determine what happens when circumstances change.
However, a contractual term does not necessarily give a business unlimited freedom to impose new prices or avoid its obligations. In consumer contracts, applicable statutory protections and rules concerning unfair terms may also need to be considered.
The precise wording of the agreement should therefore be examined before determining whether a price increase or supply disruption gives either party a right to terminate or modify the contract.
A Practical Example
Imagine that a consumer orders a television from a retailer for £2,000.
The retailer accepts the order and agrees to deliver the television within seven days.
Before delivery, the manufacturer's price increases substantially, and the retailer discovers that purchasing another unit will cost £2,700.
The retailer may argue that fulfilling the order at £2,000 is commercially unreasonable.
However, the increase in cost alone would generally not frustrate the contract.
The seller would need to establish circumstances that go substantially beyond ordinary commercial difficulty.
The position could be different if, for example, the product had become permanently unavailable, its sale had become unlawful, or an extraordinary intervening event had fundamentally changed the contractual obligation.
Why Frustration Is Applied Narrowly
The doctrine of frustration exists to deal with exceptional situations, not to redistribute ordinary commercial risks after a contract has been concluded.
If every significant movement in market prices could frustrate a contract, parties could frequently escape agreements simply because the bargain had become less profitable.
That would undermine one of the fundamental principles of contract law: contractual certainty.
The courts therefore look for a fundamental change in circumstances rather than merely an increase in cost or inconvenience.
What Should Consumers Do When a Seller Refuses to Perform?
If a seller refuses to honor an agreement because the product has become more expensive or difficult to obtain, the consumer should not automatically assume that the contract has been frustrated.
The consumer should consider:
What exactly did the original contract require?
Had the seller already accepted the order?
Was a specific product or item promised?
Does the contract contain a price-adjustment or cancellation clause?
What caused the supply problem?
Has performance actually become impossible or merely more expensive?
What statutory consumer protections apply?
What remedies are available under the contract and applicable legislation?
The answer will depend on the facts and the precise contractual terms.
Conclusion
Changes in supply and prices rarely frustrate a consumer contract.
Under English law, frustration requires an exceptional intervening event that fundamentally changes the nature of the contractual obligation. A substantial increase in price, higher production costs, supply-chain difficulties, or the need to obtain goods through a more expensive route will generally not be sufficient on their own.
Cases such as Taylor v. Caldwell, Davis Contractors Ltd. v. Fareham UDC, Tsakiroglou & Co. Ltd. v. Noblee Thorl GmbH, and Metropolitan Water Board v. Dick, Kerr & Co. Ltd. demonstrate the high threshold applied by the courts.
For consumers, the position may also be affected by statutory protections, including those contained in the Consumer Rights Act 2015.
Ultimately, the distinction is between an ordinary change in commercial circumstances and an event that fundamentally transforms the contract. Where a seller attempts to rely on increased prices or supply difficulties to avoid its obligations, the contract and applicable consumer legislation should be carefully reviewed before accepting that position.
Frequently Asked Questions
1. Can a seller cancel my order because the price of the product has increased?
Not necessarily. An increase in the seller's costs will generally not, by itself, frustrate a contract. The contractual terms and applicable consumer legislation must be considered.
2. Does a shortage of goods automatically frustrate a consumer contract?
No. A shortage may create difficulty, but frustration generally requires circumstances that make performance impossible, unlawful, or fundamentally different from the original contractual obligation.
3. Can consumers rely on the Consumer Rights Act 2015?
Potentially, yes. The Consumer Rights Act 2015 provides statutory protections for consumers in relation to qualifying contracts for goods, digital content and services. The specific rights and remedies depend on the nature of the transaction and the circumstances.
