From 1 October 2026, the time limit for bringing most Employment Tribunal claims in Great Britain will increase from three months to six months. The change will give employees more time to bring claims and means employers may need to manage the risk of potential disputes for longer.
For employers, this is more than a change to a deadline. A dismissal, grievance, disciplinary process or workplace dispute that appears to have been resolved may remain open to a potential claim for considerably longer than before.
That makes good HR processes, accurate documentation and appropriate record retention increasingly important. If a dispute resurfaces months after an employee has left, employers need to be able to establish what happened, what evidence was considered and why decisions were made.
In this guide, we’ll explain what is changing, which claims are affected, how Acas Early Conciliation fits into the process and the practical steps employers should take to prepare.
What Is Changing With Employment Tribunal Time Limits?
Currently, many common Employment Tribunal claims must generally be brought within three months less one day, subject to the relevant claim rules and any extension resulting from Acas Early Conciliation.
From 1 October 2026, the standard time limit for most Employment Tribunal claims will increase to six months less one day. The change is intended to bring the time limit for the majority of claims in line with the existing six-month period that applies to statutory redundancy and equal pay claims.
The change will affect many common employment claims, including:
- Unfair dismissal.
- Discrimination.
- Harassment.
- Victimisation.
- Unlawful deductions from wages.
- Working time claims.
- A range of other statutory employment rights.
Not every Employment Tribunal claim follows exactly the same limitation rules, so employers should not assume that every potential claim will automatically have a six-month deadline. Some claims already have longer or different time limits.
The change will generally apply where the relevant event or problem occurs on or after 1 October 2026. Issues arising before that date will generally remain subject to the existing three-month limit.
There is also a specific transitional point for breach-of-contract claims: in England and Wales, the six-month period applies where the relevant termination occurs on or after 1 October 2026, while the change for equivalent claims in Scotland begins on 9 November 2026.
For employers, the practical message is straightforward: three months without a claim will no longer necessarily mean that the risk has passed.
Does Acas Early Conciliation Still Apply?
Yes. The extension of the Tribunal time limit does not remove the requirement to notify Acas before bringing most Employment Tribunal claims.
Acas Early Conciliation gives the parties an opportunity to try to resolve a dispute without going to Tribunal. The process can affect the calculation of the relevant limitation period. The underlying process for making a claim is not changing as a result of the move to six months.
This is important for employers because contact from Acas can be the first clear indication that a former or current employee is considering legal action.
Employers should also remember that an internal grievance, disciplinary appeal or ongoing discussion with an employee does not itself stop the statutory Tribunal clock.
Internal HR processes and statutory claim deadlines should therefore be treated as separate issues.
Why Does a Longer Claim Window Matter for Employers?
The change does not simply give employees more time to bring claims. It also means employers may need to defend employment decisions for longer after the original event.
Consider an employee who leaves following a disciplinary process. Several months pass. The manager involved has changed roles, another member of the investigation team has left the business, and everyone assumes the matter has been resolved.
A claim then arrives.
The employer may suddenly need to establish:
- What happened.
- What concerns or allegations were raised.
- What evidence was considered.
- What meetings took place.
- What the employee said in response.
- Why a particular decision was made.
- Whether the appropriate procedure was followed.
Without clear records, reconstructing this information months later can be difficult.
Managers may not remember conversations accurately. Emails may be harder to locate. Witnesses may have left the organisation. Relevant digital messages may have been deleted or become difficult to retrieve.
This is why good documentation becomes even more important as the claim window becomes longer.
Is Your HR Record-Keeping Ready for the New Time Limits?
Employers should review whether their current record-keeping and retention processes are appropriate for the longer potential period during which a dispute may arise.
This could include reviewing how you store:
- Disciplinary and grievance records.
- Investigation notes and supporting evidence.
- Performance and absence records.
- Meeting notes and correspondence.
- Relevant emails and workplace messages.
- Redundancy and dismissal documentation.
- Records explaining how and why employment decisions were made.
- Acas correspondence relating to potential claims.
This does not mean keeping every employee record indefinitely.
Employers still need to comply with UK GDPR and data protection requirements and should have appropriate retention periods for different categories of information.
The objective is to have a clear and consistent retention process so that relevant evidence is not automatically deleted simply because an employee has left or an internal process has been completed.
Businesses should also consider what happens when an employee leaves. Closing an employee’s email account or removing system access should not inadvertently result in the loss of records that may be relevant to an ongoing or potential dispute.
Employment Decisions Need a Clear Paper Trail
Good record-keeping is only useful if the records actually explain what happened.
Employment decisions should therefore be documented as the process takes place rather than reconstructed after a dispute has arisen.
Depending on the situation, this may include recording:
- The original concern or allegation.
- Evidence gathered during an investigation.
- Meetings with the employee.
- The employee’s response.
- Relevant witness evidence.
- The reasoning behind the decision.
- Any disciplinary action taken.
- The outcome of an appeal.
- Any subsequent review or follow-up.
Consistency is also important.
If two employees are involved in similar conduct but receive different outcomes, the employer should be able to explain why. A clear contemporaneous record can help demonstrate that decisions were based on the circumstances of each case rather than arbitrary or discriminatory considerations.
A manager’s memory may seem sufficient when a decision is made today. Six months later, it may not be.
Are Your Managers Prepared?
Many employment disputes begin with everyday management decisions long before they reach HR or an Employment Tribunal.
Managers therefore have an important role in creating reliable records and escalating potential issues early.
Managers should understand when they need to involve HR and should be comfortable with:
- Recording important conversations and decisions.
- Following disciplinary and grievance procedures.
- Keeping clear notes during performance or conduct discussions.
- Escalating complaints and potential disputes.
- Avoiding informal messages that could undermine a later decision.
- Maintaining confidentiality when dealing with sensitive employee matters.
The aim is not to turn every conversation into excessive paperwork.
Instead, managers should understand which decisions and conversations need to be documented and why.
Clear guidance and regular training can help ensure that appropriate records are created as part of the normal HR process, rather than attempting to recreate them once a claim arrives.
Common Mistakes That Can Leave Employers Exposed
The longer claim window makes weak HR processes and poor documentation more difficult to ignore.
Common mistakes include:
Deleting records too soon
Relevant records may be automatically deleted after an employee leaves or once an internal case is marked as closed.
Relying on memory
Managers and witnesses may struggle to remember conversations accurately several months after an event.
Making important decisions informally
Verbal discussions are sometimes appropriate, but failing to document significant employment decisions can leave employers with little evidence of what happened.
Keeping incomplete investigation records
Missing meeting notes, evidence or records of the employee’s response can make it harder to demonstrate that a fair and reasonable process was followed.
Treating an internal process as the end of the matter
Completing a grievance or disciplinary procedure does not necessarily eliminate the possibility of a Tribunal claim.
Ignoring Acas correspondence
Early Conciliation notifications should be escalated promptly so the business can understand the potential claim and respond appropriately.
Forgetting insurance notification requirements
Employment protection or legal expenses insurance policies may have their own notification requirements. These can operate separately from Employment Tribunal limitation periods, so employers should check the terms of their policies.
The common thread is simple: if a business cannot clearly demonstrate what happened and why, defending its position becomes much harder.
What Employers Should Review Now
Employers do not need to wait until October 2026 to prepare.
A practical review should include:
1. Record retention
Check how long important employee and leaver records are retained and when they are automatically deleted.
2. Leaver procedures
Make sure relevant records remain accessible after an employee leaves and their accounts or system access are closed.
3. Disciplinary and grievance procedures
Confirm that investigations, meetings, evidence, decisions and appeals are properly documented.
4. Digital records
Consider how relevant emails, workplace messages and other digital evidence will be preserved when a dispute arises.
5. Manager practices
Make sure managers understand what needs to be documented and when HR should become involved.
6. Acas correspondence
Have a clear process for escalating Early Conciliation notifications quickly.
7. Insurance requirements
Check whether employment protection or legal expenses policies have separate notification deadlines.
8. HR policies and procedures
Review whether disciplinary, grievance, performance and investigation procedures provide managers with enough guidance to deal with employee issues consistently.
The aim is not to create unnecessary administration. It is to ensure that if an employment decision is challenged months later, the business still has the evidence needed to explain and support that decision.
Do the New Time Limits Apply in Northern Ireland?
The general extension from three to six months applies to Great Britain — England, Scotland and Wales.
Northern Ireland has a separate employment law and tribunal framework. However, the position is not simply that the six-month change does not apply at all: official guidance confirms that the changes also affect certain limited industrial tribunal claims in Northern Ireland, including specific claims under legislation relating to minimum wage and working time in particular sectors.
For most employers, the important point is that Great Britain and Northern Ireland should not be treated as having an identical Tribunal time-limit regime.
Businesses operating across both jurisdictions should ensure that HR teams and managers understand which rules apply to the employee and claim in question.
This is another reason why a single “UK-wide” approach to employment disputes can create unnecessary risk.

Frequently Asked Questions
How long do employees have to make an Employment Tribunal claim?
Currently, many Employment Tribunal claims in Great Britain must generally be brought within three months less one day of the relevant event, subject to the specific rules for the claim and the effect of Acas Early Conciliation.
From 1 October 2026, the standard time limit for the majority of claims will increase to six months less one day.
Which Employment Tribunal claims will move to six months?
The change covers many common claims, including unfair dismissal, discrimination, harassment, victimisation, unlawful deductions from wages and working time claims.
However, different claims can have different limitation rules, so employers should not assume that every Employment Tribunal claim automatically follows the same deadline.
Does Acas Early Conciliation still apply?
Yes. Employees generally still need to notify Acas before bringing most Employment Tribunal claims.
The process for notifying Acas is not changing because of the extension to the Tribunal time limit. Early Conciliation can affect how the final limitation date is calculated, so employers should respond promptly to any Acas notification.
Does an internal grievance or disciplinary appeal stop the Tribunal time limit?
No. An internal grievance, disciplinary appeal or other workplace procedure does not automatically stop the statutory Employment Tribunal limitation period.
Employers should therefore manage internal HR procedures and statutory claim deadlines separately.
Do employers need to keep employee records for longer?
Employers should review their retention arrangements to ensure relevant evidence remains available if a claim arises months after an employment decision.
However, this does not mean retaining every employee record indefinitely. Employers must continue to comply with UK GDPR and data protection requirements and should apply appropriate retention periods.
When should employers start preparing for the new time limits?
Employers should start reviewing their processes before 1 October 2026.
In particular, businesses should review record retention, leaver procedures, disciplinary and grievance documentation, manager training and the process for dealing with Acas correspondence.
Do the new time limits apply in Northern Ireland?
The general six-month extension applies to Great Britain. Northern Ireland has its own employment tribunal framework, although certain limited industrial tribunal claims are also affected by the changes. Employers operating across both jurisdictions should check which rules apply to the particular claim.
