Limitation Period for Disability Discrimination Claims in Employment Tribunals

Disability discrimination claims are among the most complex cases heard by employment tribunals in England and Wales. Unlike some employment disputes that arise from a single event, disability-related claims frequently involve ongoing workplace issues, repeated failures to make reasonable adjustments, lengthy sickness absence procedures, capability processes, or continuing patterns of discriminatory treatment.

Employees, workers, job applicants, apprentices, contractors in certain circumstances, and some former employees are protected against disability discrimination under the Equality Act 2010. However, regardless of the strength of a claim, strict time limits apply. Missing the applicable limitation period can result in a tribunal refusing to hear the claim altogether.

Understanding when the limitation period starts, how it is calculated, and when it may be extended is therefore essential for anyone considering legal action. This guide explains the time limits that apply to disability discrimination claims, the role of Acas Early Conciliation, the concept of continuing discrimination, and the practical issues that frequently arise in disability-related employment disputes.

What Is Disability Discrimination?

Disability discrimination occurs when an individual is treated unlawfully because of a disability or because of something connected to their disability.

Under the Equality Act 2010, a person is generally considered disabled if they have a physical or mental impairment that has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities. Certain conditions are automatically treated as disabilities for legal purposes.

Workplace disability discrimination can take several forms, including:

• Direct disability discrimination.
• Indirect disability discrimination.
• Discrimination arising from disability.
• Failure to make reasonable adjustments.
• Harassment related to disability.
• Victimisation following a complaint of discrimination.

The protection applies throughout the employment relationship, including recruitment, training, promotion, disciplinary procedures, sickness absence management, redundancy exercises, dismissal, and post-employment references.

The Legal Framework

The primary legislation governing disability discrimination is the Equality Act 2010.

Employment tribunals have jurisdiction to hear most workplace disability discrimination claims. Successful claimants may recover compensation for financial losses, injury to feelings, personal injury in appropriate circumstances, pension losses, and other consequential losses arising from unlawful discrimination.

Unlike ordinary unfair dismissal claims, compensation in discrimination cases is generally uncapped, making disability discrimination litigation particularly significant for both employers and claimants.

What Is the Limitation Period for Disability Discrimination Claims?

The standard limitation period for disability discrimination claims in the employment tribunal is:

Three months less one day from the act of discrimination complained of.

This limitation period applies to most disability discrimination claims brought under the Equality Act 2010.

Examples include:

• Refusal to provide reasonable adjustments.
• Disability-related harassment.
• Discriminatory disciplinary action.
• Discriminatory performance management.
• Disability-related dismissal.
• Refusal to recruit a disabled applicant.
• Victimisation following a discrimination complaint.

Tribunals generally apply these deadlines strictly. A claim submitted after the limitation period may be dismissed unless the tribunal exercises its discretion to extend time.

When Does the Time Limit Begin?

One of the most important questions in disability discrimination cases is identifying precisely when the limitation period starts.

Single Discriminatory Acts

Where there is a single identifiable act, time usually begins running on the date the act occurred.

Examples include:

• Refusal of a job application.
• A disciplinary warning.
• A decision not to promote an employee.
• Termination of employment.

The tribunal normally focuses on the date the decision was made and communicated rather than the date when its consequences were fully experienced.

Disability-Related Dismissal

Where a disability discrimination claim arises from dismissal, the limitation period usually runs from the effective date of termination. This is generally the last day of employment or the expiry of a notice period.

Failure to Make Reasonable Adjustments

Reasonable adjustment claims can be more complicated because they often involve omissions rather than positive acts.

Examples may include:

• Failure to provide specialist equipment.
• Failure to adjust working hours.
• Failure to modify absence management procedures.
• Failure to make workplace accessibility changes.

In these situations, determining when the failure occurred can require careful legal analysis of the facts and the employer’s decisions.

Continuing Acts of Disability Discrimination

Many disability discrimination claims involve conduct occurring over weeks, months, or even years.

Examples may include:

• Repeated failures to implement reasonable adjustments.
• Ongoing discriminatory sickness absence management.
• Continuous exclusion from workplace opportunities.
• Persistent disability-related harassment.
• Long-term refusal to accommodate medical restrictions.

The Equality Act recognises the concept of a continuing act.

Where discrimination forms part of an ongoing course of conduct, the tribunal may determine that the limitation period runs from the final act in the series rather than from the first incident. Acas explains that discrimination claims generally run from the date of the last act of discrimination relied upon in the claim.

This principle is particularly important in disability cases because workplace problems often develop gradually rather than arising from a single event.

However, tribunals distinguish between:

• A continuing discriminatory state of affairs; and
• The continuing consequences of a past decision.

For example, a single decision made years ago may not become a continuing act simply because its effects remain ongoing.

Failure to Make Reasonable Adjustments and Ongoing Breaches

Reasonable adjustment claims often generate disputes about limitation periods.

An employer’s obligation to make reasonable adjustments can arise when workplace arrangements place a disabled person at a substantial disadvantage compared with non-disabled colleagues.

Examples may include:

• Adjusted working hours.
• Home working arrangements.
• Modified duties.
• Accessible workstations.
• Additional support measures.

Where an employer repeatedly fails to implement adjustments despite ongoing requests, the claimant may argue that the failure constitutes a continuing act extending the limitation period. Whether this argument succeeds depends on the specific facts and tribunal findings.

Because these cases can involve ongoing obligations, limitation disputes frequently become a significant preliminary issue before the substantive discrimination allegations are considered.

Acas Early Conciliation and Disability Discrimination Claims

Before most employment tribunal claims can proceed, the claimant must notify Acas and engage with the Early Conciliation process.

Purpose of Early Conciliation

Acas attempts to resolve disputes without formal litigation by facilitating discussions between the parties.

The process is confidential and can result in settlement without the need for a tribunal hearing.

Effect on Limitation Periods

One of the most important features of Early Conciliation is its effect on tribunal deadlines.

Where Acas is notified within the original limitation period:

• The limitation clock is paused.
• Time effectively stops running during conciliation.
• The clock resumes when Early Conciliation ends and a certificate is issued.

Acas specifically states that Early Conciliation pauses the employment tribunal time limit when notification occurs within the applicable deadline.

Minimum Additional Time

Following the conclusion of Early Conciliation, claimants will generally have at least one month to submit their tribunal claim. Calculating the precise deadline can be complicated, particularly where multiple claims are involved.

Internal Grievances Do Not Stop Time Running

A common misunderstanding is that raising a grievance extends tribunal deadlines.

This is incorrect.

Many employees pursue internal procedures before considering tribunal proceedings. While this can be an important step, Acas makes clear that grievance procedures, appeals, investigations, capability reviews, and disciplinary processes do not automatically stop or extend the limitation period.

A claimant who waits for an employer’s final response may unintentionally miss the tribunal deadline.

Can a Tribunal Extend the Time Limit?

Unlike unfair dismissal claims, disability discrimination claims are subject to a more flexible extension test.

Section 123 of the Equality Act 2010 allows a tribunal to hear a late claim where it considers it just and equitable to do so.

When considering whether to extend time, tribunals may examine factors such as:

• The length of the delay.
• Reasons for the delay.
• Whether evidence remains available.
• The impact on both parties.
• The interests of justice.
• Whether the claimant was aware of the discrimination.
• Whether disability-related difficulties contributed to the delay.

Although the tribunal possesses broad discretion, extensions are not automatic and should not be relied upon as a substitute for complying with the normal limitation period.

Common Limitation Issues in Disability Cases

Long-Term Sickness Absence

Employees experiencing lengthy periods of sickness absence sometimes assume that tribunal deadlines are suspended while they are absent from work.

This is not generally the case.

The limitation period usually continues running unless paused through Acas Early Conciliation or extended by the tribunal.

Ongoing Workplace Adjustments

Disputes concerning workplace adjustments often involve arguments about whether the conduct constitutes a continuing act.

The answer depends heavily upon the facts and the nature of the employer’s conduct.

Capability Procedures

Capability dismissals involving disabled employees frequently give rise to allegations concerning:

• Failure to make reasonable adjustments.
• Discrimination arising from disability.
• Indirect disability discrimination.
• Unfair dismissal.

Each claim may involve different factual issues but often shares the same limitation framework.

Evidence and Record Keeping

Individuals considering disability discrimination claims should keep detailed records of relevant events.

Useful evidence may include:

• Occupational health reports.
• Medical evidence.
• Emails and correspondence.
• Adjustment requests.
• Grievance documents.
• Meeting notes.
• Sickness absence records.
• Performance management documentation.
• Acas Early Conciliation certificates.

A clear chronology can be particularly important when establishing whether conduct formed part of a continuing discriminatory course of action.

Common Questions from our Readers

How long do I have to bring a disability discrimination claim?

In most cases, three months less one day from the discriminatory act or the final act in a continuing course of discrimination.

Does Acas Early Conciliation extend the deadline?

It pauses the limitation period provided Acas is notified within the original time limit.

Does raising a grievance stop the clock?

No. Internal grievance and appeal procedures do not normally extend tribunal limitation periods.

Can a tribunal hear a late disability discrimination claim?

Potentially. Tribunals have discretion to extend time where it is just and equitable to do so. However, extensions are not guaranteed.

What if discrimination happened over a long period?

A claimant may argue that the conduct formed a continuing act of discrimination, allowing time to run from the final discriminatory act. The tribunal will determine this based on the evidence.

Final Thoughts

The limitation period for disability discrimination claims is a critical aspect of employment law. Most claims must be brought within three months less one day of the discriminatory act, although continuing acts of discrimination may allow time to run from the final act in an ongoing course of conduct.

Disability-related disputes frequently involve complex issues such as reasonable adjustments, long-term sickness absence, capability procedures, and continuing workplace treatment. These factors can make identifying the correct limitation date more challenging than in many other employment claims.

Acas Early Conciliation plays a vital role by pausing the limitation period when commenced within time, but internal grievance procedures do not normally extend tribunal deadlines. Because tribunals generally enforce limitation periods strictly, anyone considering a disability discrimination claim should identify key dates, preserve evidence, and monitor tribunal deadlines carefully.
