Learn how limitation periods apply to victimisation claims under the Equality Act 2010, including the three-month rule, continuing acts, ACAS Early Conciliation, tribunal extensions, and key timing issues in Employment Tribunal proceedings in England and Wales.

Victimisation is a specific form of unlawful discrimination prohibited by the Equality Act 2010. It occurs when a person suffers a detriment because they have carried out, intend to carry out, or are believed to have carried out a protected act, such as making a discrimination complaint, supporting another person’s complaint, or giving evidence in discrimination proceedings.
Like other Equality Act claims, victimisation claims are subject to strict limitation periods. Missing the applicable deadline can result in a claim being dismissed regardless of its merits. Understanding when the limitation period starts, how it is calculated, how ACAS Early Conciliation affects deadlines, and when extensions may be available is therefore essential for anyone considering an Employment Tribunal claim.
This guide explains the legal rules governing limitation periods for victimisation claims in England and Wales, including the practical issues that commonly arise in tribunal proceedings.
What Is Victimisation Under the Equality Act 2010?
Victimisation occurs when someone is treated unfavourably because they have carried out a protected act connected with discrimination law.
Examples of protected acts include:
- Making a discrimination complaint.
- Raising concerns about harassment.
- Supporting a colleague’s discrimination claim.
- Giving evidence in tribunal proceedings.
- Providing information that may assist a discrimination complaint.
- Alleging that discrimination has occurred.
Examples of victimisation may include:
- Being excluded from opportunities.
- Being denied promotion.
- Receiving unjustified disciplinary action.
- Being labelled a troublemaker.
- Being subjected to detrimental treatment after raising concerns about discrimination.
Victimisation is distinct from bullying or ordinary workplace disputes because it requires a connection between the detrimental treatment and a protected act under equality legislation.
The Standard Limitation Period for Victimisation Claims
Victimisation claims brought under the Equality Act 2010 generally must be presented to the Employment Tribunal within:
Three months less one day
The limitation period is governed by section 123 of the Equality Act 2010, which applies to discrimination, harassment, and victimisation claims alike.
This means that if an act of victimisation occurred on 15 January, the normal deadline for presenting a claim would ordinarily expire on 14 April, subject to any adjustments resulting from ACAS Early Conciliation.
When Does the Limitation Period Start?
A crucial issue in victimisation cases is identifying the date from which time begins to run.
Single Acts of Victimisation
Where the alleged victimisation consists of a single identifiable act, time normally runs from the date that act occurred.
Examples include:
- A disciplinary warning issued because an employee raised a discrimination complaint.
- A refusal to consider an employee for promotion after they gave evidence in tribunal proceedings.
- A dismissal allegedly linked to a protected act.
The limitation period usually begins on the date of the decision or detrimental act itself.
Ongoing Victimisation
Victimisation does not always occur as a single event. In some cases, a claimant may argue that the treatment formed part of a continuing pattern.
Examples might include:
- Repeated exclusion from meetings after raising discrimination concerns.
- A series of retaliatory management actions over several months.
- Ongoing denial of opportunities linked to a protected act.
In these circumstances, the tribunal must determine whether the conduct constitutes a continuing act.
Continuing Acts and Victimisation Claims
Section 123 of the Equality Act 2010 provides that conduct extending over a period is treated as occurring at the end of that period.
If the tribunal concludes that victimising conduct formed part of a continuing course of conduct:
- Time runs from the final act in the series.
- Earlier incidents may still be considered.
- The entire pattern of behaviour may fall within the claim.
However, tribunals do not automatically treat repeated events as continuing acts.
They examine factors such as:
- Whether the incidents were linked.
- Whether there was a common policy or approach.
- Whether the same individuals were involved.
- Whether the conduct formed part of a sustained pattern.
Separate acts may each have their own limitation period.
Victimisation Following Internal Complaints
Many victimisation claims arise after an employee:
- Raises a grievance.
- Complains about discrimination.
- Supports another employee’s complaint.
- Participates in an investigation.
A common misconception is that the limitation period begins when the grievance process concludes.
In reality:
- Time usually runs from the alleged victimising act itself.
- Internal grievance procedures do not generally stop the limitation clock.
- Waiting for an employer’s final response can create limitation risks.
This is one of the most common reasons claimants encounter timing difficulties.
Failure to Act and Victimisation
Some victimisation claims are based on alleged failures to act rather than positive actions.
Examples include:
- Refusing to investigate a complaint because a protected act was carried out.
- Ignoring concerns raised by an employee who previously complained about discrimination.
- Withholding opportunities following a protected act.
In such cases, the tribunal will examine:
- Whether there was a specific decision not to act.
- When that decision was made.
- Whether the conduct formed part of an ongoing pattern.
Determining the limitation start date can be more complex where omissions are involved.
ACAS Early Conciliation and Victimisation Claims
Before bringing most Employment Tribunal claims, a prospective claimant must notify ACAS and engage in Early Conciliation.
Effect on Limitation Periods
Where ACAS is notified within the applicable limitation period:
- The limitation clock pauses.
- The period between ACAS notification and receipt of the Early Conciliation certificate is excluded from the calculation.
- Additional statutory protection may apply if the original deadline would otherwise expire during the conciliation period.
Minimum Post-Certificate Period
If ACAS is notified in time, a claimant will normally have at least one month after receiving the Early Conciliation certificate to submit the tribunal claim.
Important Limitation
Early Conciliation does not revive a claim that was already out of time before ACAS was contacted.
Extensions of Time in Victimisation Claims
Victimisation claims benefit from the same extension provisions as other Equality Act discrimination claims.
The Just and Equitable Test
Section 123 permits the tribunal to allow a claim outside the normal limitation period where it considers this to be just and equitable.
Factors commonly considered include:
- The length of the delay.
- The reason for the delay.
- Whether the claimant understood their rights.
- The availability of evidence.
- The effect on witnesses.
- The prejudice suffered by each party.
The tribunal has a broad discretion, but extensions are not automatic.
Common Limitation Issues in Victimisation Cases
Misidentifying the Relevant Act
Claimants sometimes focus on the consequences of victimisation rather than the act itself.
The tribunal will generally look at:
- The date of the detrimental treatment.
- The date of the relevant decision.
- The final act in any continuing course of conduct.
Waiting for Internal Procedures
Employees often delay tribunal action while waiting for:
- Grievance outcomes.
- Appeals.
- Internal investigations.
These procedures usually do not suspend limitation periods.
Confusion Over Continuing Acts
Not every repeated event forms part of a continuing act.
Tribunals frequently hear disputes about whether incidents are:
- Separate acts with separate limitation periods; or
- Components of a single continuing course of victimisation.
ACAS Timing Errors
Incorrectly calculating the impact of Early Conciliation can result in claims being lodged late.
Only the tribunal can ultimately determine whether a claim was presented in time.
Compensation and Limitation Considerations
Victimisation claims can involve significant compensation where liability is established.
Potential awards may include:
- Financial losses.
- Loss of earnings.
- Future losses.
- Injury to feelings awards.
- Interest on compensation.
However, a claimant must first overcome any limitation challenge before the tribunal can consider compensation.
Consequently, limitation disputes are often among the most important preliminary issues in victimisation litigation.
Practical Considerations for Potential Claimants
Individuals considering a victimisation claim should carefully identify:
- The date of the alleged victimising act.
- Whether conduct may amount to a continuing act.
- Whether ACAS notification occurred within time.
- Whether any extension arguments may be required.
Keeping records of:
- Grievances.
- Emails.
- Meeting notes.
- Witness details.
- ACAS correspondence.
can assist in resolving limitation disputes if they arise.
Key Takeaways
Victimisation claims under the Equality Act 2010 are generally subject to a limitation period of three months less one day from the act complained of. Where victimising conduct extends over a period, tribunals may treat it as a continuing act and calculate time from the final incident. ACAS Early Conciliation pauses the limitation clock when initiated in time, but it does not revive already expired claims. Although tribunals have discretion to accept late claims where it is just and equitable to do so, extensions are not routinely granted. Correctly identifying the relevant act, calculating the deadline, and understanding the interaction between limitation rules and ongoing workplace processes are therefore essential aspects of any victimisation claim.
