Explains the limitation period for age discrimination redundancy claims in the UK, including the 3-month less 1 day rule, continuing acts, ACAS Early Conciliation, tribunal time limit extensions, and how deadlines apply in redundancy selection and dismissal cases under the Equality Act 2010.

An age discrimination redundancy claim arises where an employee believes they have been treated less favourably during a redundancy process because of their age, or that age was a factor in selection, consultation, redeployment, or dismissal decisions. These claims are brought under the Equality Act 2010, which prohibits direct and indirect discrimination, harassment, and victimisation on the basis of protected characteristics, including age.
In redundancy situations, age discrimination claims often overlap with unfair dismissal and redundancy pay issues, making time limits a critical procedural requirement. Employment Tribunal claims are strictly time-bound, and missing the limitation period can prevent a claim from being heard unless an extension is granted in limited circumstances.
Standard Limitation Period for Age Discrimination Claims
Three months less one day rule
The standard time limit for bringing an age discrimination claim in an Employment Tribunal is:
- 3 months less 1 day from the date of the discriminatory act
This applies to:
- Direct age discrimination during redundancy selection
- Indirect discrimination (e.g. redundancy criteria disadvantaging older or younger workers)
- Harassment linked to age during consultation or selection
- Victimisation connected to raising age discrimination concerns
This limitation period is set by the Equality Act 2010 framework and applied consistently across discrimination claims.
The time limit normally begins on:
- The date of the act complained of, or
- The date of the last act in a series of connected discriminatory events
How the Time Limit Works in Redundancy Situations
Age discrimination in redundancy can occur at different stages, and each stage may affect when time starts running.
1. Redundancy selection stage
If age influences scoring, selection pools, or criteria:
- Time runs from the date the decision is made or communicated
2. Consultation stage
If discriminatory comments or decisions occur during consultation:
- Each act may start its own limitation period
- Or form part of a continuing series of discrimination
3. Dismissal stage
If dismissal itself is discriminatory:
- The clock usually runs from the effective date of termination
4. Failure to redeploy
If an employer fails to offer alternative roles due to age:
- Time may run from the refusal decision or last failure in a continuing process
Continuing Acts in Age Discrimination Claims
Age discrimination in redundancy often involves multiple linked events.
Where a tribunal accepts a continuing act, the limitation period runs from:
- The last discriminatory act in the series
This can include:
- A sequence of redundancy meetings
- Repeated use of discriminatory selection criteria
- Ongoing refusal to adjust processes
If the tribunal does not treat events as continuing:
- Each act has its own separate 3-month limitation period
- Earlier incidents may be excluded if out of time
This distinction is often decisive in redundancy-related discrimination cases.
ACAS Early Conciliation and Time Limits
Before issuing an Employment Tribunal claim, the claimant must notify ACAS for Early Conciliation.
This process affects limitation periods by:
- Pausing (“stopping the clock”) the limitation period
- Extending the deadline by the duration of conciliation
Key points:
- ACAS must be contacted before the original limitation expires
- The time remaining resumes after the ACAS certificate is issued
- The extension is automatic but strictly calculated
If ACAS is contacted after time has already expired:
- The claim is already out of time
- The tribunal must rely on discretion to extend time
Extensions of Time for Age Discrimination Claims
Just and equitable extension
Employment Tribunals can extend the limitation period if it is just and equitable to do so.
This is a discretionary test under the Equality Act 2010.
Factors considered include:
- Length of delay
- Reason for delay
- Whether the claimant knew or could reasonably have known their rights
- Availability of evidence and witness reliability
- Prejudice to both parties
Tribunals apply this test strictly, and extensions are not guaranteed.
Interaction with Redundancy and Other Claims
An age discrimination redundancy case may involve multiple legal claims, each with its own time limit:
- Age discrimination: 3 months less 1 day
- Unfair dismissal: 3 months less 1 day from termination
- Statutory redundancy pay: 6 months less 1 day
- Protective award (collective redundancy): usually 3 months less 1 day
Each claim must be assessed separately when calculating deadlines.
Effective Date of Termination in Redundancy Claims
For dismissal-related claims, the limitation period usually runs from the effective date of termination (EDT), which is:
- The last day of employment
- Or the end of the notice period (if notice is worked or paid in lieu)
However, where discrimination occurs earlier (for example during selection), the limitation period may begin before termination.
Consequences of Missing the Limitation Period
If a claim is filed late:
- The employer may apply to strike out the claim
- The tribunal may refuse to hear it
- The claimant must rely on a discretionary extension
- Older events may be excluded from consideration
Even where a claim has merit, limitation rules are strictly enforced.
Practical Steps to Manage Limitation Risk
To reduce the risk of missing deadlines in age discrimination redundancy cases:
- Identify each potentially discriminatory act
- Determine whether events form a continuing series
- Calculate the 3-month less 1 day deadline for each act
- Notify ACAS before the earliest deadline expires
- Keep records of redundancy scoring, consultation notes, and communications
- Consider all related claims together (discrimination, unfair dismissal, redundancy pay)
Key Takeaways
The limitation period for an age discrimination redundancy claim in the Employment Tribunal is generally 3 months less 1 day from the discriminatory act, which may include redundancy selection decisions, consultation conduct, or dismissal. Where discrimination occurs over time, the tribunal may treat it as a continuing act, extending the start date to the last incident. ACAS Early Conciliation pauses the limitation clock, but only if initiated within time. Tribunals can extend deadlines only where it is just and equitable, making strict attention to timing essential in all redundancy-related discrimination cases.
