Limitation periods in UK commercial litigation set strict deadlines. Learn when time starts running and how to avoid your claim becoming statute-barred.

Limitation Periods in Commercial Litigation: Why Waiting Can Kill Your Claim Completely

Beth Reed April 30, 2026

A limitation period is the legal time limit for bringing a claim. If a claim is issued after this deadline, it is usually statute-barred under the Limitation Act 1980. If you miss a limitation period, your claim may be struck out entirely, regardless of its merits.

Introduction

In commercial litigation, no matter how strong your case, how clear the breach, or how significant the financial loss, a claim brought too late can be dismissed outright. This is due to limitation periods, a fundamental but often overlooked aspect of litigation that sets strict deadlines for bringing legal claims. Missing the limitation period can not only remove your ability to bring a claim, but can also make it significantly harder to gather the evidence needed to prove it.

To bring a successful commercial litigation claim, businesses must understand the importance of proactive risk management and early assessment of potential disputes. Keeping clear and accurate records of interactions with clients, suppliers, and partners can make the process of handling a litigation claim much easier. However, even the most well-documented claim can fail if it is not brought within the relevant time limits. Understanding limitation periods is therefore not just a legal technicality—it is a critical part of protecting your commercial position.

What is a Limitation Period?

A limitation period is the legally prescribed time limit within which a claimant must initiate court proceedings. If this period expires before a claim is issued, the claim will usually become “statute-barred”. This means that the court will not allow the claim to proceed, regardless of its merits, under the Limitation Act 1980.

In the England & Wales , the most common limitation periods in commercial litigation include:

6 years for most breach of contract claims from the date of cause of action accrues (usually the breach)
6 years for tort claims (such as negligence) from the date of first actionable damage
12 years for contracts executed as deeds (such as a settlement deed, transfer executed as a deed or a deed of covenant)
3 years for certain negligence claims involving latent damage (running from the date of knowledge, with an overriding 15 years longstop)

These timeframes may seem like quite a long time, but they can pass quickly—particularly in complex commercial relationships where disputes evolve gradually.

When Does Time Start Running?

One of the most important, and most misunderstood, aspects of limitation law is determining when the clock starts running.

A common assumption is that time begins when a problem is discovered. In reality, the position is often much stricter:

Contract claims: Time usually runs from the date of breach, not when the loss is discovered.
Negligence claims: Time generally runs from when damage occurs, although there are limited exceptions where the claimant’s “date of knowledge” is relevant.
Continuing breaches: These can complicate matters, but they do not necessarily restart the limitation period, often, the clock begins at the first actionable breach.

This distinction is critical. A business may only become aware of a problem years after it occurred, by which time the limitation period may already be close to expiring, or may have expired entirely.

The Practical Impact of Delay

In a commercial context, delays in bringing claims are common. Businesses may hesitate for a number of legitimate reasons:

Wanting to preserve valuable commercial relationships
Attempting to resolve disputes through negotiation
Internal uncertainty about liability or quantum of loss
Waiting to see whether issues resolve themselves

However, while these considerations are understandable, they do not stop the limitation clock from running.

Delays can have a compounding negative effect. Not only is there a risk that the claim becomes time-barred, but the quality of evidence may deteriorate over time. Documents may be misplaced or deleted, key personnel may leave the business, and memories of events may become unreliable. This can significantly weaken a claim, even if it is still technically within time.

Why Do Limitation Periods Exist?

Although it may seem harsh that a claim with strong legal merit can be dismissed purely on timing, limitation periods serve important purposes within the legal system.

Firstly, they provide certainty and finality. Businesses need to operate without the indefinite threat of litigation hanging over historic transactions. Limitation periods ensure that, after a certain point, potential liabilities are effectively closed.

Secondly, they protect the integrity of evidence. Over time, evidence becomes less reliable. Witness recollections fade, documents are lost, and reconstructing events becomes increasingly difficult. Limitation periods encourage claims to be brought while evidence is still fresh.

Finally, they promote efficiency within the courts. By preventing very old claims from being litigated, the legal system can focus on disputes where a fair and accurate determination is still possible.

The “Cliff Edge” Risk

A key feature of limitation periods is their strict, all-or-nothing nature. They operate as a hard deadline, not a flexible guideline.

If a claim is issued even one day after the limitation period expires, it is at real risk of being struck out entirely. The court has very limited discretion to extend time limits in most commercial cases, and, outside specific statutory gateways (for example in personal injury and defamation), it generally cannot disapply limitation simply because of delay.

This creates what is often described as a “cliff edge” risk. A claim issued in time can proceed in full, but a claim issued late may fail completely, regardless of its strength.

Exceptions and Extensions

While limitation periods are strict, there are some limited mechanisms that may extend or affect them:

Standstill Agreements

Parties can agree to pause the limitation clock while negotiations are ongoing. These agreements are common in commercial disputes and can provide valuable breathing space, but they must be carefully drafted to be effective.

Acknowledgment or Part Payment

If a defendant acknowledges a debt in writing or makes a partial payment, the limitation period may restart from that point.

If a defendant acknowledges a relevant debt in writing or makes a partial payment, the limitation period may restart from that point, provided the acknowledgment is in writing, signed, and made before the original limitation period has expired; once a claim is already time–barred, later acknowledgments or payments do not revive it.

Latent Damage

In certain negligence claims, time may run from the date the claimant became aware (or ought reasonably to have become aware) of the damage, subject to an ultimate longstop period.

Fraud or Concealment

In cases involving deliberate concealment or fraud, the limitation period may be postponed until the claimant discovers the wrongdoing or could with reasonable diligence have discovered it, under section 32 of the Limitation Act 1980.

However, these exceptions are narrowly applied and should not be relied upon without clear legal advice.

What Advice Do We Give to Clients?

If you suspect that you may have grounds for a commercial litigation claim, it is crucial to seek legal advice as early as possible. Early engagement allows for a proper assessment of the claim, identification of key dates, and development of a strategy that protects your position.

Taking early action provides several advantages:

Maximising the time available to investigate and gather evidence
Preserving legal options, including negotiation and settlement
Avoiding last-minute pressure as limitation deadlines approach

Where negotiations are ongoing, a standstill agreement can be used to pause the limitation period and allow discussions to continue without the risk of losing the claim.

In addition, businesses should ensure that they have robust internal systems in place to:

Identify potential disputes at an early stage
Record key contractual and transactional dates
Maintain clear and organised documentation
Escalate legal risks appropriately

Proactive management of potential claims is far more effective—and far less costly—than reacting to problems when it is too late.

The Commercial Consequences of Missing Limitation

Failing to comply with limitation periods can have serious and far-reaching consequences:

Loss of the right to bring a claim entirely (because the claim becomes statute–barred and is liable to be struck out if issued late)
Reduced leverage in negotiations, as the opposing party may know the claim is time-barred
Financial loss, potentially amounting to significant sums
Reputational damage, particularly where stakeholders expect action to be taken
Exposure to professional negligence claims, in cases where advisors fail to act in time

In high-value commercial disputes, the financial impact can be substantial. Claims worth millions may be lost—not because they lacked merit, but because they were brought too late.

Conclusion: Time Is a Critical Factor

Limitation periods are a fundamental aspect of commercial litigation that businesses cannot afford to overlook. They impose strict deadlines that operate regardless of commercial realities, negotiations, or internal decision-making processes.

In many cases, the greatest risk to a claim is not its legal strength, but the passage of time.

Businesses should therefore treat limitation as a core part of their risk management strategy. Early identification of issues, careful tracking of deadlines, and timely legal advice are essential to preserving valuable claims.
