What Is the Limitation Period for Employment Tribunal Claims Generally?

Employment Tribunal claims in England and Wales are subject to strict statutory time limits. These limitation periods determine how long a worker has to bring a claim after an employment-related issue occurs, such as dismissal, discrimination, unpaid wages, or other breaches of employment rights.

The system is designed to ensure disputes are brought promptly while evidence is still available. Missing the deadline will usually prevent the claim from being heard, regardless of its merits.

General Limitation Period for Employment Tribunal Claims

Standard rule: 3 months less one day

Most Employment Tribunal claims must be submitted within:

• 3 months less one day from the relevant act or event

This applies to the majority of employment disputes, including:

• Unfair dismissal
• Wrongful dismissal (breach of contract linked to termination)
• Discrimination claims
• Unlawful deductions from wages
• Detriment and whistleblowing claims

The general rule is confirmed in official guidance stating that most claims must be made within three months of the employment ending or the incident occurring.

When the Limitation Period Starts

The starting point depends on the type of claim:

Dismissal-related claims

The time limit usually starts from the effective date of termination (EDT), typically:

• The last day of employment where notice is worked, or
• The date of dismissal where employment ends immediately

Pay and wage disputes

The time limit begins on:

• The date the employee was not paid correctly, or
• The date of the unlawful deduction

Discrimination claims

The clock generally starts from:

• The date of the discriminatory act, or
• The last act in a series of discriminatory events

This can be important where conduct occurs over time.

ACAS Early Conciliation and Its Effect on Time Limits

Before lodging a claim, most claimants must notify ACAS and engage in Early Conciliation.

This process has a direct impact on limitation periods:

• The limitation clock is paused when ACAS is notified (if done in time)
• It remains paused during the conciliation period
• It resumes when the ACAS certificate is issued

ACAS Early Conciliation can last up to 12 weeks in some cases.

After conciliation ends, claimants usually have:

• At least 1 month from the certificate date to submit the claim (if time would otherwise have expired during conciliation)

Extended Limitation Periods (6 Months Less One Day)

While most claims follow the 3-month rule, certain Employment Tribunal claims have longer time limits:

• Statutory redundancy pay claims
• Equal pay claims
• Some trade union-related claims
• Certain armed forces-related claims

These typically allow 6 months less one day from the relevant date.

Continuing Acts and Series of Events

Some workplace issues do not occur as a single incident. In these cases, tribunals may treat the issue as:

• A continuing act, or
• A series of connected events

Where this applies:

• Time may run from the last act in the series, rather than the first
• Gaps between events may break continuity and reset limitation arguments

This is particularly relevant in discrimination and wage deduction cases.

Tribunal Discretion to Extend Time

Employment Tribunals have limited discretion to extend time limits.

Unfair dismissal and wages

• Extensions are rare
• The claimant must show it was not reasonably practicable to present the claim in time

Discrimination claims

• Tribunals may extend time if it is “just and equitable”
• This is a broader discretion but still applied strictly

Factors considered include:

• Reason for delay
• Length of delay
• Impact on the respondent
• Availability of evidence

County Court Alternative (Where Applicable)

Some employment-related disputes can be brought in the civil courts as breach of contract claims:

• Limitation period: 6 years
• Applies to certain contractual disputes outside tribunal jurisdiction limits

However, most statutory employment rights must be pursued through the Employment Tribunal system.

Common Mistakes With Limitation Periods

1. Misidentifying the start date

Incorrectly calculating the EDT or act date can result in late claims.

2. Assuming grievances pause time

Internal procedures do not usually stop or extend limitation periods.

3. Ignoring ACAS timing requirements

Failure to notify ACAS within time can prevent reliance on the pause mechanism.

4. Missing the “3 months less one day” rule

Even small miscalculations can render a claim out of time.

Practical Consequences of Missing the Deadline

If a claim is out of time:

• The tribunal will usually refuse to hear it
• The claim may be struck out without a full hearing
• Only limited exceptions may apply (extension tests or discretion)
• Alternative legal routes may be restricted or unavailable

Time limits are therefore one of the most decisive factors in employment litigation.

Key Takeaways

The general limitation period for Employment Tribunal claims in England and Wales is:

• 3 months less one day from the relevant act or termination date
• Extended by ACAS Early Conciliation if started in time
• Extended to 6 months less one day for certain statutory claims
• Subject to limited tribunal discretion in exceptional cases

Correctly identifying the start date, understanding ACAS effects, and applying the correct limitation category are essential to determining whether a claim can proceed.
