From 1 October 2026, employees will have longer to bring a number of claims before an Employment Tribunal, with many of the current three month time limits increasing to six months. For employers, this is an important change because workplace disputes may remain capable of becoming Tribunal claims for considerably longer than they do under the current rules.
The change certainly does not mean that every workplace disagreement will result in legal proceedings, but it does mean employers may need to retain evidence, manage unresolved concerns and consider potential legal risks over a longer period. A matter that appears to have gone quiet after a few months may still develop into an Acas early conciliation notification or Tribunal claim later.
Contractual Claims Will Have a Longer Time Limit in England and Wales
One of the changes taking effect on 1 October 2026 comes through the Employment Tribunals Extension of Jurisdiction (England and Wales) (Amendment) Order 2026. This extends the time limit for bringing certain Employment Tribunal claims relating to an employee's contract of employment from three months to six months.
These claims can include wrongful dismissal and disputes concerning payments or other sums that an employee believes are due under their employment contract. Wrongful dismissal should not be confused with unfair dismissal because the two claims deal with different issues. Wrongful dismissal will usually concern whether an employer breached the employment contract when ending somebody's employment, such as by failing to provide the contractual notice or notice pay they were entitled to receive.
From October, an individual in England or Wales who believes their employment contract has been breached may therefore have up to six months to present the relevant claim, subject to the applicable rules and the effect of the Acas early conciliation process.
The Changes Extend Beyond Contractual Disputes
Contractual claims are only part of the picture because separate regulations extend the time limits for several other types of Employment Tribunal complaint from three months to six months. These include certain claims involving part time workers, fixed term employees, collective redundancy consultation, zero hours contract exclusivity clauses, blacklisting and particular NHS recruitment and whistleblowing protections.
Unlike the contractual claims Order, these regulations apply across England, Scotland and Wales. The broader reforms introduced through the Employment Rights Act 2025 will also increase the primary time limit for many other Employment Tribunal claims from three months to six months, making the longer claims period increasingly important across employment law.
For employers, the practical message is that the familiar three month period can no longer be treated as the point at which many potential employment disputes have necessarily passed.
The Date of the Workplace Issue Will Matter
The move to six months does not mean that every claim presented after 1 October 2026 will automatically benefit from the longer period. The new time limits will generally apply where the relevant act, omission, treatment or infringement takes place on or after 1 October 2026, while an event that occurred before that date will normally remain subject to the previous three month limit.
This distinction will be particularly important during the transitional period because employers could be dealing with potential claims under different time limits at the same time. The date on which a claim is presented will not necessarily determine which deadline applies, so employers should avoid assuming that every claim made after October automatically receives six months.
The position can become more complicated where a complaint concerns a continuing course of conduct or a series of connected events rather than one clearly identifiable incident. In those circumstances, specialist advice may be needed to establish which rules and time limits apply.
Employers Operating in Scotland Need to Be Particularly Careful
There is also an important geographical distinction within the changes because the Order extending the time limit for contractual Employment Tribunal claims applies only to England and Wales.
Employment Tribunals can hear certain contractual claims in Scotland, but the power to amend the relevant Scottish legislation rests with Scottish Ministers. A separate Scottish Order will therefore be required to introduce an equivalent six month period for those contractual claims.
The wider regulations covering matters such as fixed term workers, part time workers, collective consultation and zero hours exclusivity clauses do apply across England, Scotland and Wales from 1 October 2026. Businesses operating across different parts of Great Britain should therefore be careful not to assume that every aspect of the reforms takes effect in exactly the same way or at exactly the same time.
Acas Early Conciliation Will Still Affect the Deadline
The longer claims period does not remove the requirement to notify Acas before most Employment Tribunal proceedings can begin. Acas early conciliation remains an important part of the process and can affect how the final deadline for presenting a claim is calculated.
The early conciliation process can pause the normal Tribunal time limit while conciliation is taking place, which means calculating the actual deadline can be more complicated than simply counting six months from the date of the incident. Employers should therefore be cautious about calculating deadlines themselves where there is uncertainty about whether a claim remains in time.
The existing rules that allow Employment Tribunals to consider whether certain claims presented outside the usual deadline should still be accepted will also continue to apply, so the six month period should not necessarily be treated as an absolute cut off in every situation.
Why the Longer Claims Window Matters for Employers
Under the current three month time limit, employers often find out relatively quickly whether a former employee or worker intends to pursue a workplace dispute formally. Once the longer time limits take effect, that period of uncertainty will increase considerably.
An employee who initially decides not to take further action will have more time to obtain advice, collect information, attempt to resolve the issue internally or simply reconsider their position. Employers could therefore receive Acas early conciliation notifications or Tribunal claims concerning matters that happened several months earlier.
The difficulty is that workplace evidence does not always become easier to find with time. Managers may have forgotten important details, employees who witnessed events may have moved to another organisation and relevant emails, messages, meeting notes or other documents may be more difficult to locate. What appeared obvious to everybody involved at the time can become much harder to establish several months later.
This is why good record keeping will become even more important once the longer time limits take effect.
Employers Should Review Their Records Before October
Businesses should use the period before October to consider how workplace concerns, grievances, disciplinary matters, dismissals and contractual disputes are currently recorded. Managers should understand the importance of keeping clear and factual notes of significant conversations and decisions rather than relying on memory if an issue resurfaces months later.
The reasons behind disciplinary action, changes to employment terms and decisions to dismiss should also be properly documented when those decisions are made. Trying to reconstruct the reasoning several months later can be extremely difficult, particularly if the manager responsible has moved role or left the organisation.
Document retention arrangements should be reviewed at the same time. Evidence relating to an employment decision should not automatically be deleted simply because three months have passed without hearing anything further from the individual concerned. Employers may need to reconsider how long they retain investigation notes, meeting records, correspondence, payroll information and documents supporting disciplinary or dismissal decisions.
This does not mean businesses should retain every document indefinitely, and appropriate data protection requirements will still need to be considered. It does mean retention practices should reflect the fact that relevant Employment Tribunal proceedings may now begin considerably later than employers have previously been accustomed to.
More Time Does Not Mean Employers Should Wait to Resolve Problems
Although extending Tribunal time limits increases the period during which an employee may bring a claim, the additional time can also create a greater opportunity for workplace disagreements to be resolved before formal proceedings become necessary.
Addressing concerns early, following fair procedures and communicating clearly with employees can help prevent misunderstandings from developing into larger disputes. Employers should therefore avoid seeing the longer claims window as a reason to delay dealing with workplace problems, because prompt action supported by good documentation will remain one of the most effective ways of protecting both the organisation and its employees.
The key date for employers is 1 October 2026, and preparation should focus on making sure managers understand that potential claims may remain live for longer than they have previously expected. Employment records should be complete, important decisions should be properly documented and retention practices should reflect the longer period during which a workplace issue could return as an Acas notification or Employment Tribunal claim.
Ultimately, the change is not simply about giving employees another three months to bring certain claims. For employers, it changes how long workplace decisions may need to be explained, evidenced and defended, which makes clear processes and reliable records more important than ever.
