Limitation Period for Breach of Commercial Contract Claims

Claims for breach of commercial contract in England and Wales are subject to statutory time limits known as limitation periods. These rules determine the maximum time within which a claimant must issue court proceedings. Once the limitation period expires, the defendant can raise a complete legal defence, preventing the claim from proceeding, even if it is otherwise valid.

The primary legislation governing these time limits is the Limitation Act 1980.

Core Limitation Period for Breach of Contract

Six-year rule for commercial contracts

The standard limitation period for breach of a commercial contract is six years.

• This applies to most simple contracts, including written, oral, and implied agreements
• The limitation period is set under section 5 of the Limitation Act 1980
• Time begins to run from the date the cause of action accrues, usually the date of breach

In most commercial disputes, this six-year period is the starting point for assessing whether a claim is still actionable.

When Time Starts Running

Date of breach as the starting point

For breach of contract claims, time normally runs from:

• The date the contractual obligation was breached
• Not the date the claimant discovers the breach (in most cases)

This can create practical difficulty where breaches are not immediately identified, but the law generally prioritises certainty over discovery.

Example

If a supplier fails to deliver goods on 1 January 2020, the limitation period usually runs from that date. The claimant must issue proceedings by 1 January 2026.

Simple Contracts vs Deeds (Specialty Contracts)

Simple contracts (6 years)

Most commercial agreements fall into this category:

• Supply of goods or services
• Consultancy agreements
• Commercial leases (contractual elements)
• Partnership agreements (contract claims)

Deeds (12 years)

Where a contract is executed as a deed:

• The limitation period extends to 12 years
• Common in certain guarantees, long-term property arrangements, and formal commercial instruments

The distinction is significant in high-value commercial transactions.

Accrual of Cause of Action in Commercial Contexts

Immediate breach claims

Where a breach occurs once (e.g. non-payment or non-delivery):

• Limitation begins immediately at breach

Repudiatory or continuing breaches

More complex contracts may involve:

• Ongoing obligations (e.g. maintenance contracts)
• Repeated failures to perform

In such cases:

• Each breach may generate a separate limitation period
• A continuing failure does not indefinitely extend time unless legally recognised as separate breaches

Anticipatory breach

Where one party indicates in advance they will not perform:

• The innocent party may treat the contract as breached immediately
• Time may begin running from acceptance of repudiation

Effect of Expiry of the Limitation Period

Once the limitation period expires:

• The claim becomes statute-barred
• The defendant gains a complete procedural defence
• The court will usually strike out or dismiss the claim if properly raised

Importantly:

• The debt or obligation is not automatically extinguished in all contexts
• Enforcement through the courts becomes unavailable

Circumstances That Can Extend or Delay Time

The Limitation Act 1980 includes limited exceptions.

Fraud, concealment, or mistake

Under section 32:

• Time does not start running until the claimant discovers, or could reasonably discover, the issue

This is particularly relevant in cases involving:

• Concealed contractual breaches
• Fraudulent misrepresentation linked to contract performance

Disability

Where a claimant lacks legal capacity:

• Time may be suspended until capacity is restored

Acknowledgment or part payment

In some contract and debt-related claims:

• A written acknowledgment of liability can restart the limitation period
• Part payment may also restart the clock in certain circumstances

Contractual Attempts to Change Limitation Periods

Commercial contracts sometimes attempt to modify limitation periods, for example:

• Extending liability periods beyond six years
• Using contractual limitation clauses or “survival clauses”

However:

• Such clauses are subject to statutory controls and reasonableness tests
• They cannot remove the court's statutory framework entirely
• Deeds are commonly used where longer enforceability is required

Interaction with Court Procedure

Issuing the claim

For limitation purposes:

• A claim is generally “brought” when the claim form is issued by the court, not merely prepared

This distinction is critical in close-to-deadline cases.

Forum

The same limitation rules apply whether proceedings are brought in:

• County Court
• High Court (King's Bench Division / Business and Property Courts)
• Arbitration (subject to the Arbitration Act 1996, but limitation principles still apply)

Practical Risks in Commercial Contract Disputes

Key risks arising from limitation rules include:

• Delay in identifying breach leading to loss of claim
• Misidentifying the correct breach date
• Assuming ongoing negotiations suspend limitation (generally incorrect)
• Failing to distinguish between multiple breaches and a single continuing breach
• Overlooking deed-based longer limitation periods

Common Questions

Does negotiation extend limitation periods?

No. Negotiations do not normally stop time running unless a formal standstill agreement is entered into.

Can a claim be brought after six years if damages are only discovered later?

Generally no, unless an exception applies (e.g. fraud or concealment).

Does partial performance restart the limitation period?

It may, depending on whether it amounts to acknowledgment of liability.

Key Takeaways

The limitation period for breach of commercial contract claims in England and Wales is generally six years from the date of breach under the Limitation Act 1980. The period extends to twelve years where the contract is executed as a deed. Time normally runs from the breach itself, not from discovery, and once expired the claim becomes statute-barred, providing a complete defence. Limited exceptions exist, particularly in cases involving fraud, concealment, disability, or acknowledgment of liability.

Careful identification of the breach date, contract type, and any potential extension provisions is essential to determining whether a claim remains enforceable.
