The deadline for bringing most Employment Tribunal claims will change significantly from 1 October 2026.
At present, many employment claims must normally be started within three months of the relevant workplace event. Under the new rules, that period will increase to six months for the majority of Employment Tribunal claims.
The reform gives employees more time to understand their legal position, collect evidence and consider possible resolution. It also gives employers a longer period during which a workplace decision may lead to Acas Early Conciliation or formal Tribunal proceedings.
However, the change does not mean that every current workplace dispute automatically receives a six month deadline.
The date of the dismissal, discriminatory act, deduction from wages or other relevant workplace event will remain important. Employees dealing with an existing dispute should not delay action because they expect the new rules to protect an older claim.
Maison Lex provides specialist employment law advice for employees and practical employment law support for employers across the UK.
What Is an Employment Tribunal Time Limit?
An Employment Tribunal time limit is the period within which a person must begin the process of bringing a workplace claim.
The applicable period normally runs from a specific legal event. Depending on the claim, this may include:
- The effective date of termination following a dismissal
- The date of an alleged discriminatory act
- The date on which wages should have been paid
- The date of an alleged detriment
- The date of a contractual breach
- The final event within a continuing series of related acts
Identifying the correct starting date is essential.
The date an employee submits a grievance, receives an appeal decision or decides that an internal process has failed may not be the date from which the legal deadline runs.
Different claims can also arise from the same workplace situation. Each claim may have its own legal starting point and limitation rules.
Employees who need a broader explanation of workplace protections can read the Maison Lex guide to rights under UK employment law.
What Is Changing on 1 October 2026?
From 1 October 2026, the time limit for bringing the majority of Employment Tribunal claims will increase from three months to six months.
The government has stated that the reform is intended to provide more time for workplace disputes to be considered, for advice to be obtained and for possible resolution before formal Tribunal proceedings begin.
This change forms part of the wider implementation of the Employment Rights Act 2025. The Act is being introduced through different commencement dates during 2026 and 2027 rather than through one single implementation date.
A detailed explanation of the wider reforms is available in the Maison Lex Employment Rights Act 2025 guide and implementation timeline.
The longer period may give employees more time, but it should not be treated as a reason to postpone advice or evidence gathering.
Employers should also prepare for disputes to remain legally active for a longer period after a workplace decision has been made.
Which Employment Tribunal Claims Will Be Affected?
The extended deadline will apply to the majority of claims that currently have a three month time limit.
This may include claims involving:
- Unfair dismissal
- Workplace discrimination
- Unlawful deductions from wages
- Whistleblowing detriment
- Certain contractual disputes
- Breaches of statutory employment rights
The precise deadline will continue to depend on the legal claim, the relevant facts and the date on which the workplace event occurred.
Employees considering a dismissal claim can review the Maison Lex complete guide to unfair dismissal in the UK.
A resignation can also raise different legal questions where an employee believes that serious employer conduct left them with no reasonable option but to leave. Further guidance is available in the Maison Lex article explaining constructive dismissal in the UK.
Equal Pay Claims Already Have a Longer Time Limit
Equal pay claims currently operate under different limitation rules from many discrimination and dismissal claims.
An equal pay claim is generally subject to a six month period running from the end of the relevant employment, while many other Equality Act claims have traditionally been subject to a three month period. The Employment Rights Act 2025 is intended to reduce this difference by extending the time limit for other Employment Tribunal claims.
Employees and employers can read more about the developing position in the Maison Lex guide to UK equal pay reform in 2026.
The six month reform should still not be treated as one universal calculation for every employment claim. The legal starting point and the type of claim must be checked separately.
The Date of the Workplace Event Will Matter
One of the most important parts of the reform is its transitional position.
The new six month period will generally apply where the relevant workplace event happens on or after 1 October 2026.
Where the event happens before 1 October 2026, the existing limitation period may continue to apply, even where the deadline itself falls after the commencement date.
For example, an employee dismissed shortly before 1 October 2026 should not assume that the approaching reform has automatically doubled the time available to start the claim.
By contrast, a dismissal or relevant workplace event occurring after the new rules take effect will generally fall within the extended period.
This means that two employees facing similar situations several days apart may have different deadlines.
The correct date should therefore be calculated from the relevant legal event rather than from the date on which the employee first obtained advice.
Does Acas Early Conciliation Still Apply?
The requirement to notify Acas has not been removed.
Before bringing most Employment Tribunal claims, a prospective claimant must normally notify Acas and consider Early Conciliation.
Early Conciliation provides an opportunity for the employee and employer to explore possible resolution before formal proceedings progress. The underlying process will continue after the time limits increase.
Acas notification can affect the calculation of the final Tribunal deadline. This can become technical where:
- Several workplace events are involved
- More than one legal claim may exist
- Events occurred on different dates
- A continuing act is alleged
- The Acas certificate is issued close to the original deadline
Employees should avoid calculating the final deadline through an informal estimate or a general online date calculator.
The responsibility for notifying Acas within the relevant time limit normally remains with the prospective claimant.
Does Raising a Grievance Extend the Tribunal Deadline?
Raising a grievance does not automatically stop or extend the Employment Tribunal deadline.
The same principle generally applies where an employee is waiting for:
- A disciplinary outcome
- A grievance decision
- An internal appeal
- A response from human resources
- The completion of an investigation
- A settlement proposal
- A subject access request
Acas expressly confirms that grievance, disciplinary and appeal procedures do not change the applicable Tribunal time limit. A person may still need to notify Acas before the internal procedure has concluded.
The move to six months may reduce some immediate pressure, but it does not suspend the limitation period while the parties continue internal discussions.
Employees attending a disciplinary process may also find the Maison Lex guide on preparing for a disciplinary hearing at work useful.
Questions about evidence and workplace recordings can raise separate legal and practical issues. Maison Lex has also explained the position on secretly recording a disciplinary meeting in the UK.
What Should Employees Do Before the Rules Change?
Employees with an existing workplace dispute should first identify when the relevant legal event occurred.
A dispute that began before 1 October 2026 may remain subject to the previous limitation period, even where grievances, appeals or settlement discussions continue after the new rules take effect.
Important documents should be preserved, including:
- Employment contracts
- Dismissal or resignation letters
- Grievance correspondence
- Disciplinary documents
- Payslips
- Performance reviews
- Relevant emails and messages
- Notes of workplace meetings
- Copies of relevant policies
- Records showing when decisions were communicated
Employees should also separate the strength of the underlying complaint from the deadline for bringing it.
A person may have substantial concerns about how they were treated, but the Tribunal must still have jurisdiction to consider the claim. Missing the deadline can create a serious procedural problem regardless of the merits of the dispute.
Employees facing changes to pay, duties, hours or other contractual terms can also review the Maison Lex guide explaining when an employer can change a contract without consent.
Can a Late Employment Tribunal Claim Still Be Considered?
A claimant may attempt to present a claim after the normal time limit has expired.
This does not mean that the Tribunal will automatically accept it.
The Tribunal has limited discretion to consider certain late claims. The applicable test depends on the type of claim being brought.
A discrimination claim may involve a different test from an unfair dismissal claim. The Tribunal may consider the explanation for the delay, the circumstances surrounding it and the particular statutory requirements.
Government guidance confirms that late claims may be considered on a case by case basis, but there is no guarantee that an extension will be granted.
Employees should therefore avoid relying on judicial discretion as an alternative to meeting the correct deadline.
A potentially strong claim can still fail to proceed where it was started too late.
What Does the Change Mean for Employers?
The longer limitation period will also affect employers.
A workplace matter that appears to have concluded internally may still lead to Acas notification or Tribunal proceedings several months later.
Employers should consider reviewing:
- Employment contracts and staff handbooks
- Grievance and disciplinary policies
- Dismissal and appeal procedures
- Manager training materials
- Document retention practices
- Settlement authority and approval processes
- Internal reporting of legal disputes
- Insurance notification requirements
- Exit procedures
- Records explaining significant workplace decisions
Official guidance recommends that employers update policies and employee handbooks that continue to refer to a three month Tribunal time limit.
Managers should also record the reasoning behind employment decisions while the facts remain clear.
An unclear dismissal letter, undocumented performance concern or incomplete meeting note may become harder to explain several months after the event.

Will the Extended Deadline Lead to More Claims?
The additional time may allow some employees to obtain advice and consider a claim where they might previously have missed the shorter period.
It could also provide more time for employers and employees to resolve disputes through internal procedures, direct negotiation or Acas Early Conciliation.
The practical result will depend on how the parties use the additional period.
An employer that investigates concerns promptly, communicates decisions clearly and considers settlement constructively may be able to resolve a dispute before formal proceedings are issued.
A delayed or poorly documented response may allow the dispute to become more difficult and expensive to manage.
The extended period should therefore be treated as an opportunity for structured resolution rather than inactivity.
Could the Dispute Be Resolved Through a Settlement Agreement?
A settlement agreement can be used to resolve an existing or potential workplace dispute without a final Employment Tribunal hearing.
Under a settlement agreement, an employee normally agrees to waive specified legal claims in return for an agreed financial package and other contractual terms.
The agreement may address:
- Compensation
- Notice pay
- Outstanding wages or holiday pay
- Bonuses or commission
- An agreed employment reference
- Confidentiality
- Return of company property
- Post termination restrictions
- Legal fees
- The termination date
A settlement agreement must meet specific legal requirements. The employee must receive independent advice from a qualified adviser before the agreement can become legally binding.
Employees who have received an agreement can read the Maison Lex guide explaining what a settlement agreement is and how it works.
Maison Lex also provides dedicated advice through its settlement agreement solicitors service.
The longer Tribunal deadline may give the parties more time to negotiate, but discussions should not continue without a clear understanding of the applicable legal deadline.
Practical Example
Consider two employees who believe that they were unfairly dismissed.
The first employee’s employment ends before 1 October 2026. The previous limitation period may continue to apply because the relevant dismissal occurred before the new rules took effect.
The second employee is dismissed after 1 October 2026. The new six month period will generally apply.
The claims may appear similar, but the deadlines may be different.
The employer may also need to retain documents and prepare for possible proceedings over a longer period in the second case.
This example shows why the date of the relevant workplace event must be established before any Tribunal deadline is calculated.
What Should Employers and Employees Do Now?
Employees should not delay action on the assumption that every existing dispute will soon receive a six month deadline.
Employers should not assume that a workplace issue has ended simply because three months have passed.
Both parties should:
- Identify the relevant workplace event
- Record the date accurately
- Understand the possible legal claims
- Preserve important evidence
- Consider internal resolution
- Check whether Acas notification is required
- Obtain advice before the deadline becomes uncertain
The reform provides more time, but it does not make Employment Tribunal deadlines less important.
In some cases, the longer period may allow the parties to resolve the dispute. In other cases, it may extend uncertainty and increase the importance of reliable records and early legal advice.

Frequently Asked Questions
When will the Employment Tribunal time limit increase?
The time limit for the majority of Employment Tribunal claims will increase from three months to six months on 1 October 2026.
Will the six month deadline apply to existing disputes?
Not automatically. The date of the relevant dismissal, deduction, discriminatory act or other workplace event will need to be considered.
Will I still need to notify Acas?
Yes. Most prospective claimants will still need to notify Acas before bringing Employment Tribunal proceedings.
Does raising a grievance pause the deadline?
No. A grievance, disciplinary procedure or internal appeal does not automatically stop or extend the Employment Tribunal deadline.
Will equal pay claims receive a new time limit?
Equal pay claims already operate under a longer limitation period. The October 2026 reform principally affects claims that are currently subject to a shorter period.
Can an employer and employee settle during Acas Early Conciliation?
Yes. Acas Early Conciliation gives the parties an opportunity to explore resolution before formal Tribunal proceedings continue.
Can the Tribunal accept a late claim?
A Tribunal may consider certain late claims, but acceptance is not automatic. The applicable legal test depends on the type of claim and the reasons for the delay.
