Employment Tribunal Time Limit Change to 6 Months: Full Details for 2026

Employment Tribunal Time Limit Change to 6 Months If you are considering making an Employment Tribunal claim, one date matters more than almost anything else: the deadline. Until now, the general rule for most Employment Tribunal claims has been that you have three months less one day to start the process. That relatively short window can be difficult to manage, particularly where you are still trying to resolve the dispute internally, going through a grievance or negotiating with your employer. That is changing. From 1 October 2026, the time limit for most Employment Tribunal claims will increase from three months to six months. The change is being introduced as part of the Government’s employment law reforms and is intended to give employees and employers more time to resolve workplace disputes before a claim needs to be brought. But there is an important point here. The new six-month limit does not mean that every existing employment dispute suddenly has another three months added to its deadline. Transitional rules determine which time limit applies, so the date on which the relevant employment problem occurred can make a significant difference. What Are the Current Employment Tribunal Time Limits? At the moment, most Employment Tribunal claims have a time limit of three months less one day. The exact date depends on the type of claim. For an unfair dismissal claim, for example, the time limit normally runs from the effective date of termination. For a discrimination claim, it usually runs from the date of the discriminatory act, although a continuing course of conduct can make the calculation more complicated. For pay claims, the relevant date will depend on the particular payment issue. Acas currently explains that most claims have a three-month-minus-one-day deadline, while certain claims already have a six-month-minus-one-day time limit. These include statutory redundancy pay claims and equal pay claims, among others. That distinction is important because the law is not currently operating on one universal Employment Tribunal deadline. When Does the Employment Tribunal Time Limit Change to 6 Months? The change takes effect on 1 October 2026. From that date, the time limit for most Employment Tribunal claims will increase from three months to six months. The Government’s current implementation timetable confirms that the change will take effect on 1 October 2026. There is a separate commencement date for certain breach of employment contract claims in Scotland. For those claims, the change takes effect on 9 November 2026.  In England and Wales, the relevant breach of contract change takes effect on 1 October 2026. For most readers dealing with employment disputes in England and Wales, therefore, 1 October 2026 is the key date to remember. What Does the New 6-Month Deadline Mean? The change is significant because it gives people more time to decide whether to bring a claim. Under the current system, three months less one day can disappear surprisingly quickly. An employee may first raise a grievance. The employer may investigate it. There could be an appeal. The parties may then discuss a settlement. By the time all of that has happened, a substantial part of the Tribunal limitation period may already have passed. From 1 October 2026, the longer limitation period should provide more breathing space in many cases. However, it is important not to treat the six-month period as a reason to delay. Employment disputes can involve complicated facts, multiple potential claims and different limitation dates. Waiting until the end of the available period can create unnecessary pressure and may make it harder to obtain documents, identify witnesses and build a case. Does the Six-Month Time Limit Apply to Claims Before 1 October 2026? This is one of the most important questions surrounding the change. The new six-month limit will generally apply to claims where the relevant problem occurs on or after 1 October 2026. Where the relevant problem occurred before that date, the existing three-month time limit will generally continue to apply. That means employees with an existing dispute should not simply wait until October and assume the new rules will apply. For example, imagine an employee is dismissed on 15 September 2026. Under the existing rules, the relevant limitation period will generally be based on the current three-month-minus-one-day framework. By contrast, if an employee is dismissed on 5 October 2026, the new six-month regime will generally apply. The exact calculation can become more complicated where there are multiple acts, continuing discrimination or more than one potential claim. How Long Do You Have to Make an Employment Tribunal Claim in the UK? For most claims arising from 1 October 2026 onwards, the basic time limit will be six months less one day. That does not mean you have six calendar months from the moment you decide to take legal action. The clock usually starts from the relevant event giving rise to the claim. For example, in an unfair dismissal case, the relevant date will normally be the effective date of termination. For discrimination, the calculation may be based on the date of the discriminatory act or the last act in a continuing course of conduct. This is why simply adding six months to the date you think the dispute started can sometimes produce the wrong answer. If there is any doubt, obtain legal advice and calculate the deadline carefully. Does Acas Early Conciliation Still Apply? Yes. The change to six months does not remove the requirement to notify Acas before bringing most Employment Tribunal claims. If you are considering a claim, you will normally need to notify Acas and go through the Early Conciliation process before submitting your Tribunal claim. The process itself has not changed because of the new six-month limitation period. Early Conciliation gives the parties an opportunity to resolve the dispute without going to Tribunal. If an agreement is reached, Acas can record it in a legally binding COT3 agreement. If the dispute is not resolved, Acas issues an Early Conciliation certificate. The claimant can then proceed with an Employment Tribunal claim, subject to the applicable limitation rules. What Happens If You Miss the Employment Tribunal Deadline? Missing the deadline does not necessarily mean that a Tribunal claim is automatically impossible. However, the position can become considerably more difficult. Employment Tribunal time limits are generally strict. In some circumstances, a Tribunal has discretion to accept a late claim, but the rules differ depending on the type of claim and the reason for the delay. You should therefore never rely on the possibility of a Tribunal extending the deadline. If you believe your deadline has already passed, it is still worth obtaining legal advice immediately. The fact that a claim is late does not necessarily mean there are no options, but you need to understand the specific rules that apply to your case. Does Raising a Grievance Extend the Tribunal Deadline? No. This is an important point that employees sometimes discover too late. You might raise a formal grievance with your employer and wait for the outcome before deciding whether to bring a Tribunal claim. You might also appeal the grievance decision. That internal process does not automatically extend the Employment Tribunal limitation period. So, if you are considering a claim, you need to keep the Tribunal deadline in mind even while an internal process is ongoing. Does the Change Mean Employees Should Wait Longer Before Taking Action? Not necessarily. The purpose of extending the limitation period is to give people more time, not to encourage them to leave everything until the last minute. There can be good reasons for taking advice early. An employment solicitor can help identify the potential claims, preserve evidence, assess the strength of the case and work out the relevant deadlines. Early advice can also help with settlement negotiations or a grievance before the relationship deteriorates further. The additional three months may provide useful breathing space, but it does not remove the need for careful planning. What Does the Change Mean for Employers? The longer limitation period is not only relevant to employees. Employers should also understand that workplace disputes may remain capable of turning into Tribunal claims for longer. That makes good HR processes even more important. A business dealing with a disciplinary matter, grievance, redundancy, discrimination complaint or dismissal should keep appropriate records and deal with issues properly at the time. It is not sensible to assume that a dispute will disappear simply because the employee has not brought a claim within the old three-month period. For employers, the longer time limit may also mean that settlement discussions and internal procedures need to be handled with greater awareness of the potential litigation window. What Claims Will Have the Six-Month Time Limit? The reform is intended to increase the time limit for the majority of Employment Tribunal claims. The change is broad, but there are different rules for particular claims and jurisdictions, so it would be unsafe to assume that every employment-related claim will have exactly the same deadline. Some claims already have longer limitation periods. For example, statutory redundancy pay and equal pay claims currently have six-month-minus-one-day time limits under the existing rules. There are also special rules around certain contractual claims and claims involving particular categories of workers. The safest approach is to identify the specific legal claim first and then calculate its limitation period. A Simple Example of the New Rules Imagine an employee is dismissed on 10 October 2026. Because the dismissal takes place after the new rules come into force, the six-month limitation period will generally apply to an ordinary unfair dismissal claim. The employee should still notify Acas within the applicable limitation period and then take account of the Early Conciliation rules when calculating the final deadline for presenting the Tribunal claim. Now consider a different employee who was dismissed on 10 September 2026. The fact that the new 6-month rule comes into force a few weeks later does not generally mean that the employee  can simply wait until March 2027 to bring their claim. The existing rules will generally apply to the earlier event. This is why the transition between the old and new rules needs careful attention. What Should You Do If You Are Considering an Employment Tribunal Claim? Do not start with the calendar alone. Start by understanding what has happened and what legal claims may potentially arise. You should consider: Identify the relevant event Was it a dismissal, discriminatory act, unpaid wages, redundancy or something else? Check the applicable limitation period Do not assume every claim has the same deadline. Keep your evidence Save relevant emails, letters, messages, contracts, payslips, meeting notes and other documents. Consider internal procedures A grievance or appeal may be appropriate, but remember that it does not automatically extend the Tribunal deadline. Get legal advice where necessary A solicitor can help you identify the potential claims and calculate the relevant deadlines. How KLG Law Can Help Employment Tribunal deadlines can look straightforward until you have an actual dispute in front of you. A single workplace situation can potentially involve more than one claim, and each may have its own rules. The position can become even more complicated when there are continuing acts, internal appeals, Early Conciliation or transitional rules involved. At KLG Law, our employment solicitors advise employees and employers on employment disputes, Tribunal claims and limitation issues. We can help you understand the legal position, assess your options and make sure you are approaching the matter with the relevant deadlines in mind. If you are unsure about employment tribunal time limits, do not wait until the deadline is approaching before getting advice. Final Thoughts The move from three months to six months is one of the more significant changes to employment tribunal time limits in 2026. From 1 October 2026, most Employment Tribunal claims will have a six-month limitation period instead of three months. But the change does not apply retrospectively to every existing workplace dispute, and the exact deadline can depend on the type of claim and the date on which the relevant event occurred. The safest approach is still to act promptly. If you believe you have an employment claim, do not assume that having six months means you can leave the matter until the final few weeks. Get advice, understand the claim, protect your evidence and establish the correct limitation date as early as possible.
