Employment Tribunal discrimination claim time limits explained, including the three-month deadline, continuing acts, ACAS Early Conciliation rules, and when tribunals may extend time on a just and equitable basis under the Equality Act 2010.

Discrimination claims in the Employment Tribunal arise under the Equality Act 2010 and cover unlawful treatment based on protected characteristics such as sex, race, disability, age, religion or belief, sexual orientation, gender reassignment, and pregnancy or maternity.
Although discrimination claims can be legally complex and fact-sensitive, they are also highly time-sensitive. Strict deadlines apply, and missing them can prevent a claim from being heard, regardless of its strength.
This article explains the legal time limits for bringing discrimination claims, how those limits are calculated, how Early Conciliation affects deadlines, and when tribunals may allow late claims.
Standard Time Limit for Discrimination Claims
The general time limit for bringing a discrimination claim in the Employment Tribunal is:
Three months less one day from the date of the discriminatory act.
This applies to claims under the Equality Act 2010, including:
- Direct discrimination
- Indirect discrimination
- Harassment
- Victimisation
- Failure to make reasonable adjustments
Example
If a discriminatory act occurs on 10 January, the deadline is usually 9 April.
What Counts as the “Date of the Act”?
Identifying the correct starting point is critical. The time limit usually begins from the date when the discriminatory act occurred. However, this can be more complex than a single event.
The relevant date may be:
- The date of a discriminatory decision (for example, refusal of promotion)
- The date of a dismissal
- The date of a specific incident of harassment
- The date an employer failed to make reasonable adjustments
In some cases, the discrimination may not be a single act but part of a broader pattern.
Continuing Acts and Ongoing Discrimination
Discrimination often occurs over time. In such cases, the tribunal may treat multiple incidents as part of a continuing act.
Where a continuing act is established:
- The time limit runs from the last act in the series
- Earlier incidents may still be considered as part of the overall claim
Example
An employee experiences repeated harassment over several months. The tribunal may treat the entire course of conduct as a continuing act, meaning the limitation period starts from the last incident.
However, tribunals apply this carefully. Not all repeated complaints will qualify as a continuing act; isolated incidents separated by time may be treated individually.
ACAS Early Conciliation and Its Effect on Time Limits
Before issuing a discrimination claim, most individuals must notify ACAS for Early Conciliation.
This process affects limitation periods:
- The time limit is paused while Early Conciliation is ongoing
- It resumes when ACAS issues a certificate ending the process
Practical impact
The limitation period is effectively extended by the duration of Early Conciliation, which can range from days to several weeks.
If the time limit is close to expiring when ACAS is contacted, it is possible for the deadline to pass during conciliation, but the law preserves the right to proceed once the certificate is issued.
“Just and Equitable” Extension of Time
Unlike some employment claims, discrimination claims have a more flexible approach to late applications.
Under section 123 of the Equality Act 2010, tribunals may allow a claim to proceed outside the normal time limit if it is considered just and equitable to do so.
This is a discretionary test. There is no automatic extension.
Factors the tribunal may consider include:
- Length of delay and reasons for it
- Whether the claimant was aware of their rights
- Whether evidence is still available and reliable
- Whether the employer would suffer prejudice due to delay
- Whether the claimant acted promptly once aware of the issue
- The overall fairness to both parties
Important point
The burden is on the claimant to justify the delay. Tribunals do not extend time automatically.
Difference from Unfair Dismissal Time Limits
Discrimination claims differ from unfair dismissal claims in one key respect:
- Unfair dismissal: strict “not reasonably practicable” test
- Discrimination: flexible “just and equitable” discretion
This means discrimination claims may sometimes proceed even after significant delay, but success is not guaranteed.
Common Situations Affecting Time Limits
1. Ongoing workplace grievance procedures
Internal grievances do not stop the tribunal time limit. Employees often assume waiting for an outcome preserves their rights, but the limitation period continues to run.
2. Resignation followed by later awareness
In some cases, individuals only later realise that treatment was discriminatory. Delay in recognition may be considered under the “just and equitable” test, but it does not automatically extend time.
3. Multiple incidents over time
Where there are repeated incidents, identifying whether they form a continuing act is crucial. If not, each incident may have its own limitation period.
4. Disability-related issues
In disability discrimination cases, failures to make reasonable adjustments may be ongoing. This increases the likelihood of a continuing act argument, depending on the facts.
Why Time Limits Matter in Discrimination Claims
Time limits in discrimination cases serve several purposes:
- Ensuring evidence remains reliable
- Encouraging prompt resolution of workplace disputes
- Providing certainty for employers
- Avoiding prolonged exposure to historic allegations
However, tribunals also recognise that discrimination may not always be immediately obvious, which is why the “just and equitable” discretion exists.
How to Calculate the Deadline
To calculate the limitation period:
- Identify the date of the discriminatory act
- Add three calendar months
- Subtract one day
- Adjust for ACAS Early Conciliation (pause period)
- Confirm the final filing date with the Employment Tribunal
Because errors are common, careful attention to dates is essential.
Practical Steps When Considering a Claim
Individuals considering a discrimination claim typically:
- Record all relevant incidents and dates
- Identify potential protected characteristics involved
- Keep written evidence such as emails or messages
- Contact ACAS Early Conciliation as soon as possible
- Avoid delaying while internal processes are ongoing
- Prepare a clear timeline of events
Early action reduces the risk of missing strict deadlines and losing the right to bring a claim.
Common Questions from our Readers
What is the time limit for discrimination claims in the Employment Tribunal?
Generally, three months less one day from the date of the discriminatory act, subject to ACAS Early Conciliation and possible tribunal discretion.
Can the tribunal accept a late discrimination claim?
Yes, if it considers it just and equitable to do so, but this is discretionary and not guaranteed.
Does ACAS Early Conciliation extend the time limit?
Yes. The limitation period is paused while ACAS Early Conciliation is ongoing.
Do ongoing workplace issues extend the deadline?
Only if they are legally treated as a continuing act of discrimination.
Is ignorance of the law a valid reason for delay?
Generally, no. However, tribunals may consider all circumstances when applying the just and equitable test.
Key Takeaways
Discrimination claims in the Employment Tribunal must usually be brought within three months less one day of the discriminatory act. The deadline can be extended by ACAS Early Conciliation and may be further relaxed where it is just and equitable for the tribunal to allow a late claim.
Correctly identifying the date of the act, recognising continuing discrimination, and acting promptly are critical to preserving legal rights. Although tribunals have discretion to accept late claims, reliance on this is uncertain, making early action essential.
