Employment Tribunal Time Limits: The 2026 Rules Explained

September 3, 2026

Miss an employment tribunal deadline, and your claim can be over before it starts. These limits are strict, and once they pass, a tribunal will only rarely let a late claim through. Knowing how your deadline works, and what can pause or extend it, is often the difference between having your day in tribunal and losing the right to be heard.

This guide sets out the time limits that apply to employment claims, how to work out your own deadline, and what happens if you miss it. Whether you are weighing up a claim for unfair dismissal, discrimination or unpaid wages, understanding where you stand puts you on much firmer ground.

A key change to employment tribunal time limits from 1 October 2026

The deadline for bringing most tribunal claims depends on when the event you are complaining about took place, not when you decide to claim.

• For events on or after 1 October 2026, the standard time limit is six months less one day. This follows the Employment Rights Act 2025, which doubled the previous limit.
• For events before 1 October 2026, the older limit of three months less one day applies.
• Where your complaint covers a series of linked events, such as repeated unlawful deductions from your pay or discrimination, it is the date of the last event that decides which limit applies.

A dismissal on 15 September 2026 falls under the three-month rule, while a dismissal on 15 October 2026 falls under the six-month rule. If you are not sure which side of the line your situation falls on, seek advice quickly rather than assuming you have the longer period.

Why employment tribunal time limits matter

Employment tribunals resolve disputes between employees and employers, and they work to a tight timetable. Deadlines exist so claims are brought while events are recent, evidence is intact, and memories are fresh.

Miss yours, and you may lose the right to have your claim heard at all. That is why speed matters. The moment something goes wrong at work, whether it is a dismissal, a discriminatory act or a pay error, the clock starts running.

Common employment tribunal claims

Employees bring all sorts of tribunal claims. Among the most common are:

• Unfair dismissal, where you believe you were dismissed without a fair reason or a fair process.
• Discrimination, connected to a protected characteristic such as age, sex, race, religion or disability.
• Unlawful deduction from wages, where your employer has not paid you what you are owed.
• Redundancy pay disputes, including claims for statutory redundancy pay.
• Equal pay, where you are paid less than a colleague of the opposite sex doing equal work.

Each type has its own rules, and in some cases its own deadline.

How long you have to make a claim

For most claims, the deadline turns on the six-month or three-month rule set out above, depending on the date of the event. The table below summarises the main deadlines.

For example, if a pay error happened on 2 November 2026, after the 1 October change, add six calendar months to reach 2 May 2027, then take off one day. Your deadline is 11:59 pm on 1 May 2027. For an event before 1 October 2026, you would use three months less one day instead of six and work it out the same way.

Which claims have long carried a six-month limit?

A group of claims carried a six-month limit even before the 2025 changes, including:

• Statutory redundancy pay claims.
• Equal pay claims.
• Unfair dismissal claims connected with industrial action.
• Certain claims against a trade union.

From 1 October 2026, six months becomes the norm for most claims too, so for events on or after that date most employees will have the same longer deadline. Breach of contract claims brought in the employment tribunal in England and Wales also move to a six-month limit from that date.

What decides when the clock starts?

Working out exactly when your deadline begins can be less obvious than it sounds. As a rule, it runs from the date the problem happened, but the precise starting point depends on the claim:

• Unfair dismissal: the clock starts on the effective date of termination. This is usually the last day of your notice period, or the date of dismissal if you were dismissed without notice.
• Pay and wages: it starts on the date you should have been paid correctly but were not.
• Discrimination: it starts on the date of the last discriminatory act you are including in your claim.

Things get more involved where your situation covers more than one type of claim, or where there have been several incidents. One point catches many people out: going through a grievance, disciplinary or appeal process does not extend your deadline. Even if those steps run on for months, you still have to contact Acas before your time limit expires.

How to work out your employment tribunal time limit

The basic method is simple:

1. Identify the trigger date, meaning the date the problem happened, such as your dismissal or a pay error.
2. Add the number of calendar months that applies to your claim, either three or six depending on the date of the event.
3. Take off one day. That gives your final deadline, which ends at 11:59 pm.

Be careful with dates near the end of a month, where adding calendar months does not always land neatly. If you are unsure which date applies, or your claim includes several issues, get legal advice early. A miscalculation here can cost you the claim.

How does Early Conciliation affect your deadline?

Before you can bring most claims, you must first notify Acas. This starts a process called Early Conciliation, in which an independent conciliator speaks separately to you and your employer to see whether an agreement can be reached. Many disputes settle at this stage, often through a settlement agreement.

Contacting Acas pauses your time limit while Early Conciliation runs, but only if you contact them within your original deadline. The conciliation period can now last up to twelve weeks for notifications made on or after 1 December 2025, and the days spent in conciliation do not count towards your limit. Once conciliation ends, Acas issues a certificate, and you then have at least one month from the date on that certificate to lodge your claim if the ordinary deadline has already passed or is close.

If you notify Acas too late, you lose the benefit of this pause altogether.

Failure to engage in the Early Conciliation process could have repercussions on any compensation awarded by a tribunal.

What happens if you miss the employment tribunal time limit?

If your deadline passes, you can still submit a claim, but there is no guarantee it will be accepted. A tribunal judge decides whether to let a late claim proceed, and in most cases the limits are applied strictly.

The test the judge uses depends on the claim. For unfair dismissal, a judge will usually only extend time where it was not reasonably practicable for you to claim in time. For discrimination, the question is whether it is equitable to allow more time. Neither test is easy to meet, so relying on an extension is a gamble.

Can the employment tribunal time limit be extended?

In limited situations, yes. The usual grounds are:

• It was not reasonably practicable for you to claim in time, for example because of serious illness or because you were misled about your rights.
• It is just and fair to extend, a more flexible test that mainly applies in discrimination cases.

To ask for extra time, you would have to explain to the tribunal why you missed the deadline and back it up with evidence. Extensions are the exception rather than the rule, so the safest course is always to act well inside your time limit rather than hope for leniency.

Exceptions worth knowing about

Beyond the standard deadlines, a few situations work differently:

• Interim relief: in certain automatic unfair dismissal cases, such as whistleblowing or trade union dismissals, you can apply for interim relief within just seven days of your dismissal. This is where you can ask to continue receiving pay and benefits until the final hearing. This can help keep you afloat financially while your claim is decided, and the application is not subject to Early Conciliation.
• Continuing acts: where discrimination or unlawful deductions form part of an ongoing series, the deadline can run from the last act rather than the first.
• Multiple claims: if your case brings together several types of claim, different deadlines might apply to each.

These situations can be complex, so advice is well worth having if your circumstances do not fit the standard pattern.

Helpful advice for the tribunal process

A few simple habits give you the best chance of a good outcome:

• Act straight away. Do not wait for a grievance or appeal to finish before checking your deadline.
• Note the trigger date. Record the exact date the problem happened and work out your limit at once.
• Notify Acas within time limits. This protects your position and opens the door to a possible settlement.
• Keep records. Save relevant emails, payslips and correspondence to support your claim. It is also helpful to keep a chronology of key events such as dates of meetings or discussions.
• Seek legal advice. An experienced employment solicitor can confirm your deadline and strengthen your case.

Frequently asked questions

What is the time limit for an employment tribunal claim?

For events on or after 1 October 2026, most claims must be started within six months less one day of the date the problem happened. For events before that date, the limit is three months less one day. In almost all cases, you must notify Acas before the deadline expires.

Has the employment tribunal time limit changed in 2026?

Yes. Under the Employment Rights Act 2025, the standard limit for most claims rises from three months less one day to six months less one day for events on or after 1 October 2026. Which limit applies depends on the date of the event, not the date you claim.

Which claims have a six-month time limit?

Statutory redundancy pay and equal pay claims have long carried a six-month limit, along with certain claims linked to industrial action, certain claims against a trade union, and certain claims by members of the armed forces. From 1 October 2026, six months also becomes the standard limit for most other claims.

Can an employment tribunal time limit be extended?

Sometimes. A tribunal may extend the deadline provided that it was not reasonably practicable to claim in time (for unfair dismissal), or if it is equitable to do so (mainly in discrimination cases). Extensions are rare, so it is safer to claim within your limit.

How does Early Conciliation affect my deadline?

Notifying Acas to start Early Conciliation pauses your time limit while the process runs, provided you contact them within your original deadline. Conciliation can last up to twelve weeks, and once it ends you have at least one month from the certificate date to lodge your claim if the deadline has passed or is near.

What happens if I miss the employment tribunal time limit?

You can still submit a claim, but a tribunal judge decides whether to accept it. In most cases, the limits are applied strictly, so tribunals often reject late claims.
