What Is Consideration in a Commercial Contract?

Consideration is one of the fundamental requirements for a legally binding commercial contract in England and Wales. It refers to the exchange of value between the parties to an agreement. Without consideration, a promise is generally not enforceable as a contract, even if both parties intended to be bound.

In commercial settings, consideration is central to enforceability, as it distinguishes a binding contract from a mere gift or informal promise. It is a key concept used by courts when determining whether obligations can be legally enforced through damages, claims, or other remedies.

The Legal Definition of Consideration

The classic definition of consideration comes from Currie v Misa (1875), where it was described as:

• A right, interest, profit, or benefit gained by one party, or
• A forbearance, detriment, loss, or responsibility given or undertaken by the other party.

In simple terms, consideration is what each party brings to the bargain.

In commercial contracts, this usually takes the form of:

• Payment of money
• Supply of goods
• Provision of services
• A promise to do or not do something

Why Consideration Is Required in Contract Law

English contract law requires consideration to ensure that agreements are genuine exchanges rather than one-sided promises. It helps courts distinguish between:

• Binding commercial agreements, and
• Gratuitous promises (which are generally not enforceable)

This principle is part of common law doctrine and applies across most business transactions unless the contract is executed as a deed, which does not require consideration.

The Core Principles of Consideration

1. Consideration Must Move from the Promisee

Only a party who has provided consideration can enforce a contract.

This means:

• A person must give something in exchange to claim the benefit of the contract
• Consideration does not need to move directly between the two parties, but it must be provided by the claimant

This principle is illustrated in Dunlop Pneumatic Tyre Co Ltd v Selfridge & Co Ltd (1915), which confirmed that only a party to whom consideration is provided can enforce contractual obligations.

2. Consideration Must Be Sufficient, Not Adequate

The courts require consideration to have legal value, but they do not assess whether it is economically fair.

This means:

• Even a small or nominal amount can be valid consideration
• The courts will not intervene simply because the deal is commercially unequal

For example, £1 can be valid consideration if it forms part of a genuine agreement.

However, consideration must not be illusory or meaningless.

3. Past Consideration Is Not Valid

Consideration must be given in exchange for the promise at the time of contracting. Something done before a promise is made is generally not valid consideration.

This principle was confirmed in Re McArdle (1951).

Example:
If a contractor voluntarily completes repair work and the client later promises payment, that promise is not usually enforceable because the work was completed before the promise was made.

4. Existing Duties Are Generally Not Enough

Performing an existing legal or contractual duty is usually not valid consideration for a new promise.

However, there are important exceptions in commercial practice, particularly where additional benefit is obtained.

Key Exceptions in Commercial Contracts

1. Part Payment of Debt

Under Pinnel's Case (1602) and Foakes v Beer (1884), paying part of a debt is not normally sufficient consideration for discharge of the full debt.

However, exceptions may apply if:

• Payment is made earlier than required
• Payment is made in a different form (e.g. goods instead of money)
• Payment is made to a third party with creditor agreement

2. Practical Benefit Rule

Modern commercial law recognises that practical benefits can amount to valid consideration.

In Williams v Roffey Bros & Nicholls (Contractors) Ltd (1991), the court held that if one party obtains a practical benefit or avoids a disadvantage, this may be sufficient consideration.

Example:
A contractor agrees to complete work on time for the same price after renegotiation because the employer avoids penalty costs and project delays. The practical benefit can support a valid variation of the contract.

3. Promissory Estoppel

Where one party relies on a promise and changes their position, courts may prevent the promisor from going back on their word, even without formal consideration.

This principle was established in the High Trees case (Central London Property Trust Ltd v High Trees House Ltd (1947)).

Promissory estoppel typically applies where:

• A clear promise has been made
• There is reliance on the promise
• It would be unfair to allow the promisor to withdraw it

However, it is generally a defensive doctrine and does not create a new cause of action.

Consideration in Commercial Contract Variations

Commercial contracts often change over time. For a variation to be enforceable, it must usually include fresh consideration unless it falls within recognised exceptions.

Common issues include:

• Increased workload without increased payment
• Changes in delivery obligations
• Extensions of deadlines without adjustment

Businesses often address this by including variation clauses in contracts, setting out how changes will be agreed and enforced.

Consideration in Modern Business Practice

In practice, consideration in commercial contracts often appears in structured forms such as:

• Service agreements (fees for services)
• Supply contracts (goods for payment)
• Licensing agreements (usage rights for royalties)
• SaaS agreements (subscription payments for software access)

Electronic contracting has not changed the requirement for consideration, but it has made it easier to document exchanges of value through digital signatures and automated payment systems.

Legal Risks Where Consideration Is Missing or Defective

If consideration is absent or invalid, a contract may be unenforceable. This can lead to:

• Inability to recover losses through courts
• Disputes over unpaid invoices or services
• Challenges in enforcing verbal agreements
• Uncertainty in business relationships

Common problem areas include informal agreements between businesses, unclear renegotiations, and reliance on verbal promises without documented exchange.

Time Limits for Claims Involving Consideration Issues

If a dispute arises relating to a breach of contract where consideration is in question, the standard limitation periods apply:

• 6 years from the breach for standard contracts
• 12 years for contracts executed as deeds

These limits are set under the Limitation Act 1980.

Common Questions from our Readers

Is consideration always required in a commercial contract?

Yes, unless the contract is made as a deed. Deeds are binding without consideration but require formal execution.

Can a small payment count as consideration?

Yes. The law requires legal sufficiency, not economic equivalence.

Is a promise to do something in the future valid consideration?

Yes, provided it forms part of a reciprocal exchange between the parties.

Can contracts be enforced without consideration?

Generally no, unless promissory estoppel applies or the contract is executed as a deed.

Key Takeaways

Consideration is a core requirement in commercial contract law in England and Wales. It refers to the exchange of value between parties and ensures that agreements are legally enforceable rather than informal promises. While the courts do not assess fairness, they require that each party provides something of legal value.

Key principles include that consideration must move from the promisee, must be sufficient but not necessarily adequate, and must not be past or purely nominal. Important exceptions exist, including practical benefit and promissory estoppel, which reflect modern commercial realities.

Understanding consideration is essential for businesses to ensure contracts are valid, enforceable, and capable of supporting legal remedies in the event of dispute.
