Missed the Tribunal Deadline? What You Can Do

This article applies to England, Wales and Scotland.

In brief: Missing the tribunal deadline is serious but not always final. Check first whether you are actually late: where discrimination continued over time the clock runs from the last incident. Note that a few dismissal claims, including whistleblowing, carry a separate seven-day interim relief deadline that cannot be extended.

Last updated: August 2026

By Yerty | This guide was created using analysis of tribunal cases and official ACAS/Gov.uk guidance.

You have worked out that the deadline has passed. Maybe by three days, maybe by three months. You are trying to find out whether that is the end of it, and most of what you have read so far has told you to "seek urgent legal advice" without telling you anything about where you actually stand.

This guide explains how late claims are treated, what the two tests are, and what our analysis of published tribunal decisions shows about how often extensions are actually granted.

Important: This guide provides information about UK employment law. Yerty is not a law firm and does not provide legal advice. Every situation is different. Data describes past cases and cannot predict the outcome of any individual application. If you are outside the deadline, consider getting advice quickly.

Read This First If You Were Dismissed in the Last Week

Most of this guide concerns the three-month deadline. A small group of dismissal claims carry a far shorter one, and unlike every other limit on this page it cannot be extended at all.

Interim relief is an application to keep your pay running while your claim proceeds. Under section 128 of the Employment Rights Act 1996 it must be presented before the end of the period of seven days immediately following the effective date of termination. The Act contains no provision allowing a tribunal to extend that period.

It is available where the principal reason for dismissal was one of a defined list, including:

making a protected disclosure (whistleblowing)
designated health and safety duties, or acting as a health and safety representative or safety committee member (s.100(1)(a) and (b) only, not every health and safety dismissal)
acting as a working time or employee representative
trade union membership or activities
selection on a prohibited blacklist

You also do not need an ACAS certificate first. Interim relief applications are one of the express exemptions from mandatory early conciliation under the 2014 Regulations.

If you were dismissed within the last seven days for any of those reasons, that is the deadline that matters today, not the three-month one. Consider taking advice immediately.

There Are Three Questions Here, Not One

Almost everything written about missed deadlines answers a single question: will the tribunal forgive me? It is a fair question, and it is the weakest of the three worth asking.

Am I actually late? More people than you would expect are not.
If I am late, will the tribunal let me in anyway? This is where most guides start.
If I get in, is the claim worth pursuing? Almost nobody publishes an answer to this.

This guide takes them in that order, because the first is the strongest position available and it is the one people give away by conceding it too early.

Missing the deadline does not automatically end your claim. Both the Employment Rights Act 1996 and the Equality Act 2010 give tribunals power to allow a late claim, and you are entitled to ask them to use it.

In the cases we can see, nearly everyone asks. Of the decided out-of-time cases in our dataset, only around 2% had no extension application recorded. That describes cases that reached a published judgment. It cannot tell you how many people miss a deadline and never claim at all, because those people never appear in the record.

When it goes wrong, it usually goes wrong completely. In our sample, around 95% of cases where the deadline was missed lost the whole claim rather than part of it.

What Changes on 1 October 2026

The time limit for most tribunal claims increases from three months to six months on 1 October 2026, under the Employment Rights Act 2025. For breach of contract claims in Scotland the change comes on 9 November 2026.

The date that matters is when the thing happened, not when you claim.

If you were dismissed, or the act you are complaining about took place, before 1 October 2026, your deadline is still three months less one day. If it happened on or after that date, you have six months. Where the treatment was a course of conduct rather than a single act, it is the date of the last act that decides.

That means two people reading this page in November 2026 can have completely different deadlines depending on when their employment ended. If your case is from before the change, the new six-month limit does not rescue you.

The provisions are enacted and the government timetable gives 1 October 2026, which is what ACAS currently publishes. Some implementing and transitional instruments were still completing their passage when this guide was written. The direction is settled; check for updates before relying on a specific date.

Are You Actually Late?

Start here, not with the extension. A meaningful share of people who believe they have missed the deadline have not, and conceding lateness you did not need to concede gives away the stronger position by default.

Your claim	The clock starts	Where it says so
Unfair dismissal	The effective date of termination	s.111(2) Employment Rights Act 1996
Discrimination	The date of the act complained of	s.123(1) Equality Act 2010
Discrimination, ongoing treatment	The end of the period	s.123(3)(a) Equality Act 2010
Discrimination, a failure to do something	When the employer decided not to do it	s.123(3)(b) Equality Act 2010

Two of those rows catch people out.

A failure to act. If your complaint is that your employer refused to do something, such as withholding a reference or never answering a grievance, the law treats the clock as starting when they decided, not when you found out. Section 123(4) says that decision is taken to have been made either when they did something inconsistent with acting, or when the period in which they might reasonably have been expected to act ran out.

Treatment that continued. Where discrimination amounted to conduct extending over a period rather than a one-off act, section 123(3)(a) treats it as done at the end of that period, so the clock runs from the last point rather than the first.

This is narrower than it sounds, and the distinction is where these arguments are won and lost. A run of separate incidents is not automatically conduct extending over a period. In Hendricks v Commissioner of Police for the Metropolis [2002] EWCA Civ 1686 the Court of Appeal framed the question as whether there was "an act extending over a period, as distinct from a succession of isolated or specific acts for which time would begin to run from the date when each act was committed", directing tribunals to look at whether the employer was responsible for an ongoing situation or a state of affairs.

So a continuing discriminatory regime, policy or persistent course of treatment may qualify. Three unrelated incidents eighteen months apart, each complete in itself, generally will not, and in that situation each has its own deadline.

In our analysis, tribunals considered a continuing act argument in 2,335 cases:

Tribunal found	Claims in time	Claims out of time
Continuing act established	485	143
Continuing act rejected	19	1,681
Other or not classified	7

Where the argument was accepted, 77% of those claims were in time. Where it was rejected, 99% were out.

The 143 in that first row matter. Establishing a continuing act does not by itself make you in time. It moves the start date to the end of the conduct, and you still have to have claimed within the limit running from that point. Those 143 claimants won the argument and were late anyway.

Across the cases we examined where a claim escaped a time bar, around a third got through by showing they were never late rather than by being forgiven for it, 548 cases against 990.

The two routes are still not equivalent. Where a continuing act is established and the claim was brought in time from the end of it, you are in time as of right: no discretion, no balancing exercise, no judgment about whether you deserve it. Asking for an extension puts you at the mercy of a discretion that succeeds between roughly 13% and 22% of the time, and which on the unfair dismissal route has not succeeded at all in our data where the claim was more than a year late.

The argument succeeds in around 27% of the cases where it is run, which is unremarkable in itself. What matters is what winning it gets you.

A single dismissal has no continuing act. A sustained course of harassment very well might. Around 91% of these arguments are run in cases involving a discrimination claim, because section 123(3) is an Equality Act provision.

Note also that the three-month limit is three months less one day. Dismissed on 15 January, your deadline is 14 April.

The Two Different Tests: Which Applies to You?

This is the most important thing on this page, and our data says it matters more than most guides suggest.

	Unfair dismissal and most Employment Rights Act claims	Discrimination and Equality Act claims
The test	Was it "not reasonably practicable" to claim in time?	Is it "just and equitable" to allow it?
The question	Could you have claimed in time?	Is it fair to let you claim now?
How hard	Stricter	More flexible

The wording matters. Section 111(2)(b) of the Employment Rights Act allows a late unfair dismissal claim only "within such further period as the tribunal considers reasonable in a case where it is satisfied that it was not reasonably practicable" to claim in time. Section 123(1)(b) of the Equality Act simply allows "such other period as the employment tribunal thinks just and equitable".

One asks about your capability. The other asks about fairness. They are genuinely different questions, and they produce genuinely different answers.

What the Data Shows

We analysed published Employment Tribunal decisions from 2000 to 2026 where a tribunal ruled on whether a late claim could proceed. Three findings from that analysis should change how you think about your own position.

Being slightly late helps far less than you would think. At one to seven days late, around 78% of applications were still refused. A claim one week late and one a month late are close to the same bet, 22.2% against 22.4%. There is no forgiving cliff-edge just past the deadline, and being a few days over is not the obviously excusable position most people assume it is.

Which test applies to you matters more than how late you are. At the same delay of one to seven days, a discrimination claim was extended 44.1% of the time against 11.1% for unfair dismissal. That gap appears at every length of delay, and it is wider than the gap between a claim a week late and one over a year late.

These are observed rates rather than a controlled comparison. Discrimination and unfair dismissal cases differ in more than the test applied to them, so we cannot say the test alone produces the gap. What we can say is that the just and equitable discretion is legally broader, and that in our sample it produced substantially higher extension rates at every delay.

Extensions appear to be getting harder. The observed grant rate fell from 17.3% (2019–21) to 13.4% (2023–26), down more than a fifth, while the proportion of claims lost on time limits stayed broadly flat. We would not present that as proof tribunals have become stricter, since the mix of cases reaching a published judgment changes over time. But the direction is consistent, and it arrives immediately before the deadline itself doubles.

The full analysis, including the complete breakdown by length of delay, what happens to claims after they get past the deadline, and our full method and its limits, is set out in our data report on tribunal time limit extensions.

What this means for you

If your claim is under the Equality Act, the position is meaningfully better than the headline figures suggest, and length of delay is not decisive. If your claim is unfair dismissal with no discrimination element, the position is harder: of late unfair dismissal claims brought with no discrimination claim alongside them, around 5.5% were allowed to proceed, roughly one in eighteen. That is the extension being granted, not the case being won. It is the most common claim type, under the strictest test, with nothing to soften it.

What to do next

You may still have options. Find out which apply to you.

Check your options

Neither figure is a reason not to apply. There is no tribunal fee for presenting a claim, and applying preserves the possibility of the tribunal considering it where not applying removes it. That is not the same as saying an application is free of cost: it takes time, preparation and emotional effort, and tribunals can in defined circumstances make costs orders against claimants. Taking advice can help you weigh that.

One thing worth knowing before you decide it is not worth the effort. Of claims that did get past the deadline, roughly seven in ten went on to succeed at a merits hearing, with a median award of £12,856. Those claimants are a heavily selected group, though. Apparent merit is weighed in some admission decisions, only cases producing a published judgment are visible at all, and anyone who won on time and then settled never reached a merits hearing. The point stands nonetheless: for these claimants the time limit was the gate, not the case.

Test 1: "Not Reasonably Practicable"

This applies to unfair dismissal, unlawful deductions from wages, whistleblowing detriment and most other Employment Rights Act claims.

Redundancy payments are the exception and are more generous. Section 164 of the Employment Rights Act gives six months from the relevant date, not three, and then allows a further six months where it appears to the tribunal "just and equitable" that the payment should be made. If your claim is for a statutory redundancy payment, neither the three-month limit nor the test below applies to it.

The leading authority is Palmer and Saunders v Southend-on-Sea Borough Council [1984] ICR 372, where the Court of Appeal held the question is whether it was "reasonably feasible, having regard to all the relevant circumstances," for the claim to be presented in time.

Not knowing about the deadline rarely helps. In Wall's Meat Co Ltd v Khan [1979] ICR 52 the Court of Appeal held that ignorance or mistake only assists where the claimant's state of mind was itself reasonable, and not where it "arises from the fault of the claimant". Our data agrees: of the reasons appearing in these judgments, ignorance of the time limit is the one that leans towards refusal.

But the test is meant to be read generously. Marks and Spencer plc v Williams-Ryan [2005] ICR 1293 confirmed it should have "a liberal interpretation in favour of the employee", and tribunals must make clear findings about why a claim was late (London International College v Sen [1993] IRLR 333), so your explanation will be examined rather than skimmed.

There is a second hurdle that catches people out. Section 111(2)(b) does not stop at "not reasonably practicable". The claim must then have been presented "within such further period as the tribunal considers reasonable". So even where something genuinely prevented you claiming in time, delay after that obstacle lifted can still sink the application. If you were in hospital until March, a claim in April is a very different proposition from one in August.

Test 2: "Just and Equitable"

This applies to discrimination, harassment and victimisation claims under the Equality Act 2010, and it is the more forgiving of the two, as our figures show.

It is also broader. The tribunal weighs everything relevant rather than working through a fixed list. In Adedeji v University Hospitals Birmingham NHS Foundation Trust [2021] EWCA Civ 23 the Court of Appeal warned against mechanically applying the checklist borrowed from the Limitation Act 1980, holding that tribunals should assess all relevant factors "including the length of, and reasons for, the delay".

"More forgiving" is not the same as forgiving. Adedeji itself is the warning, and we cover it below.

How ACAS Conciliation Affects Your Deadline

In almost all cases you must contact ACAS for early conciliation before submitting a claim. There are narrow exemptions, including where you are applying for interim relief, where another claimant has already conciliated the same dispute and you are joining their claim, and where the employer contacted ACAS first. For everyone else it is a mandatory step, and it pauses your deadline in two separate ways that are easy to conflate. Under section 207B of the Employment Rights Act, and its Equality Act equivalent:

Day A is the day you contact ACAS. Day B is the day you receive your certificate.
The period from the day after Day A until Day B is not counted towards your time limit.
Separately, if your deadline would have expired between Day A and one month after Day B, it instead expires at the end of that month.

Most explanations mention the first rule and miss the second. The conciliation period itself also lengthened from six weeks to twelve for cases notified on or after 1 December 2025, so the pause available is longer than older guidance describes.

One limit that is easy to miss: the pause only operates on a deadline that is still running. Contacting ACAS after the limit has already expired does not revive it, because there is no clock left to stop.

In the judgments we analysed, discussion of the Day A and Day B calculation appeared around 1.4 times more often in decisions granting an extension than refusing one. That is an association in our sample rather than proof the rules help, but it does not support the common assumption that conciliation dates are a frequent cause of claims failing. They are still worth calculating carefully, because when they go wrong the consequence is total.

Real Examples: When Tribunals Say Yes and No

Three days late, and refused. In Adedeji, a consultant surgeon filed three days after the deadline. He had already received his ACAS certificate and believed contacting ACAS again would restart the clock. His own legal adviser had warned him twice. The Court of Appeal refused to extend time. It described him as "a highly educated man with ready access to legal advice", and found that he had not acted on the advice he was given.

Three days, an honest misunderstanding, professional advice available, no extension. Our data confirms this is not an aberration: at that degree of lateness roughly four in five applications fail.

Five years late, and granted. At the other end, around a quarter of granted extensions ran to more than six months, and one was allowed five years out of time. Tribunals plainly do allow very late claims where the circumstances justify it.

The lesson from the pair matches the lesson from the table: no length of delay is automatically fatal, and none is automatically safe.

How to Explain Your Delay to the Tribunal

Whichever test applies, you are being asked to account for the whole period, not just the moment you realised.

Be specific about dates. A tribunal will want to know when you learned of the right to claim, what happened in the intervening weeks, and when you acted once you knew.

Explain the reason, not the feeling. Illness, a hospital admission, a disability affecting your ability to deal with paperwork, or wrong information from someone you were entitled to rely on are all things a tribunal can weigh. "I was overwhelmed" is true for almost everyone and distinguishes you from nobody.

Do not overstate. If part of the delay has no good explanation, say so. An account that collapses under questioning is worse than a modest one that holds.

On a common situation: many people wait for an internal grievance or appeal to conclude before claiming. An internal process does not extend your deadline, and you may want to consider starting ACAS conciliation while a grievance is still running. Our data does not show that waiting for a grievance is treated as a poor reason, so if that is what happened, explain it plainly rather than apologising for it.

What to Do Right Now

Options available to you include:

Contact ACAS today if you have not already. In almost all cases you need a certificate before you can submit a claim, and conciliation may pause a deadline that has not yet fully run on parts of your claim. The main exception is an interim relief application, which is exempt and carries its own seven-day deadline.

Check whether you are actually late before conceding that you are. Where treatment continued over a period, the clock may run from the last incident rather than the first, and where you have several claims some may be in time even if others are not. This is the strongest position available and the easiest one to give away.

Identify which test applies. If any part of your claim is discrimination under the Equality Act, the more flexible test applies to that part, and on our figures that materially changes the picture.

Submit as soon as you can. Delay after discovering the problem is itself a factor.

Get advice quickly if you can. Represented claimants obtained extensions more often in our analysis. The comparison is not like-for-like, and Adedeji shows advice only helps if followed, but an extension application is a discrete legal argument and advice suits it well.

Common Myths About Late Claims

"A few days late will be fine." It usually is not. Around 78% of applications at one to seven days late were refused in our analysis, and the Court of Appeal upheld a refusal at three days in Adedeji.

"I did not know about the deadline, so they will understand." Ignorance only assists where it was itself reasonable, and not where it arose from your own fault. It is the reason that leans most towards refusal.

"My grievance was still running, so the clock was paused." An internal grievance or appeal does not extend the tribunal deadline. Only ACAS early conciliation does that.

"Contacting ACAS again gives me more time." It does not. This was the mistake in Adedeji, and the claim was lost on it.

"All my incidents count as one continuing act." Not automatically. A continuing discriminatory situation or state of affairs can count as one act ending at the last point. A run of separate, self-contained incidents usually cannot, and each keeps its own deadline. This is the distinction tribunals spend most time on.

"The deadline has passed, so I am late." Not necessarily. Where discrimination continued over a period the clock runs from the last incident. Around a third of claims that survive a time bar do so by establishing they were never late.

"If I am late, there is no point applying." In the decided cases we analysed, roughly one in five extension applications on the discrimination route succeeded. Not applying removes even that possibility.

If the Tribunal Route Closes

Worth knowing, and rarely said: missing the tribunal deadline does not necessarily end every claim you have.

Employment tribunals can hear certain breach of contract claims arising on termination, subject to a cap. But breach of contract is also an ordinary civil claim, and in England and Wales section 5 of the Limitation Act 1980 allows six years from the date the cause of action accrued. Different rules apply in Scotland.

This does not rescue every claim. Unfair dismissal, discrimination, whistleblowing and most other employment rights are creatures of statute and can only be brought in an employment tribunal, within the tribunal's time limits. If those are gone, they are gone. What may survive is a genuinely contractual claim.

So if part of what you have is contractual (unpaid notice, a bonus owed under your contract, sums due under its terms), the tribunal deadline may have passed while the civil route remains open.

Understand the costs difference before going near it. In an employment tribunal each side normally pays its own costs whatever the outcome. In the civil courts the general rule is that the losing party pays the winner's costs, which can substantially exceed the sum in dispute. That is a materially different risk from the one you have been weighing up to this point, and it is a decision to take advice on rather than act on alone. But the route existing at all is worth knowing, and for some readers it is the difference between a closed case and a live one.

The Bottom Line for Workers

Missing the deadline is serious and usually, though not always, fatal. Take the three questions in order.

Check first whether you are actually late. Around a third of the claims that survive a time bar do so by never having been late. That route puts you in time as of right rather than at the mercy of a discretion.

If you are late, establish which test applies. In our sample the difference between the two tests was wider than the difference between a short delay and a long one.

And if you get through, the claim is worth having. There is no fee for presenting a claim, and not applying converts a difficult case into a closed one. That is a reason to consider applying, not a promise that it will work.

Frequently Asked Questions

Can I still claim if I have missed the employment tribunal deadline? Yes. You can ask the tribunal to extend time. Whether it is granted turns on which legal test applies to your claim. In the decided cases we analysed, discrimination claims were extended considerably more often than unfair dismissal claims at the same length of delay.

How late is too late for an employment tribunal claim? There is no fixed cut-off. Around a quarter of granted extensions were more than six months out of time, and one was allowed five years late. Equally, roughly 78% of applications made within a week of the deadline were still refused.

What is the difference between "just and equitable" and "not reasonably practicable"? "Not reasonably practicable" applies to unfair dismissal and most Employment Rights Act claims, and asks whether claiming in time was reasonably feasible. "Just and equitable" applies to Equality Act discrimination claims and asks whether allowing the late claim is fair. The second is more flexible.

Does the tribunal time limit change in October 2026? Yes. From 1 October 2026 the limit for most claims increases from three months to six months under the Employment Rights Act 2025, with 9 November 2026 for breach of contract claims in Scotland. The date of the act decides which limit applies, not the date you claim.

Does raising a grievance pause the tribunal deadline? No. An internal grievance or appeal does not extend the time limit for a tribunal claim. Only ACAS early conciliation pauses the clock, under section 207B of the Employment Rights Act 1996 and its Equality Act equivalent.

Does not knowing about the deadline count as a reason? Rarely on its own. Ignorance or a mistake only assists where the claimant's state of mind was itself reasonable, and not where it arose from their own fault. It is the reason most associated with refusal in the judgments we analysed.

How does ACAS early conciliation affect my deadline? The period between contacting ACAS and receiving your certificate is not counted towards the limit. Separately, if the deadline would expire between that first contact and one month after the certificate, it expires at the end of that month instead.

Am I definitely late if the deadline has passed? Not necessarily. Where discrimination continued over a period, section 123(3) of the Equality Act treats it as done at the end of that period, so the clock runs from the last incident. In our analysis, around a third of claims that survived a time bar did so this way.

Is there ever a deadline shorter than three months? Yes. An application for interim relief under section 128 of the Employment Rights Act must be presented within seven days of the effective date of termination, and there is no power to extend it. It applies to a defined list of dismissals including whistleblowing, union activities, blacklisting, and the narrower health and safety categories in s.100(1)(a) and (b) of the Act, meaning designated safety duties or acting as a safety representative or committee member. Other health and safety dismissals, such as leaving a place of danger, are not within it.

Do repeated incidents always count as one continuing act? No. Section 123(3) covers conduct extending over a period, which the Court of Appeal in Hendricks treated as an ongoing situation or state of affairs rather than a succession of isolated acts. Separate, self-contained incidents generally each carry their own deadline.

Is a claim allowed in late still worth pursuing? On our figures, yes. Around 70% of claims rescued by an extension went on to succeed at a merits hearing, with a median award of £12,856. Those claimants are heavily selected, though: merit is weighed in some admission decisions, only published cases are visible, and those who settled after winning on time never reached a merits hearing.

Can I still claim breach of contract if I have missed the tribunal deadline? Possibly. Breach of contract is also an ordinary civil claim, and in England and Wales the Limitation Act 1980 allows six years from when the cause of action accrued. Different rules apply in Scotland. It is a different forum with different costs risks, so take advice.

Are extensions getting harder to obtain? Our analysis suggests so. The grant rate fell from 17.3% (2019–21) to 13.4% (2023–26), a drop of more than a fifth, while the proportion of claims lost on time limits stayed broadly flat.
