Employment Tribunal Time Limits Double on 1 October 2026: Scope and Preparation

Reviewed and updated: 28 September 2026. This guide covers the main changes in Great Britain, with the limited Northern Ireland scope noted below. It corrects earlier statements about unfair-dismissal dates, tribunal volumes and record-retention requirements.

From 1 October 2026, the primary time limit for most employment tribunal claims increases from three months minus one day to six months minus one day. The change depends on the claim's relevant starting date and type. It does not automatically give every existing dispute a new six-month deadline.

Which claims and dates are affected?

The government's time-limit guidance confirms the main October change and the transitional rules. For claims within the reform, the relevant event or starting date must fall on or after commencement. A pre-October dismissal does not gain the new limit simply because a claim is submitted later.

Claim or circumstance	What to check
Most claims covered by the reform	The new primary limit applies where the relevant starting date is on or after 1 October 2026.
Breach of employment contract in Scotland	The change takes effect on 9 November 2026, based on the applicable termination date.
Statutory redundancy pay and equal pay	These already have a six-month primary period; they are not newly doubled from three months.

The change applies across England, Wales and Scotland. In Northern Ireland it applies only to specified industrial-tribunal claims under minimum-wage, maritime-hours and civil-aviation working-time legislation. The official guidance links to the relevant scope; do not apply this summary to every Northern Ireland claim.

How does Acas early conciliation affect the deadline?

Acas explains how to identify the starting date, including the effective termination date for unfair dismissal and the relevant act for pay or discrimination claims. Continuing conduct, multiple claims and exceptions can make the calculation more complex. Some applications, such as interim relief, have much shorter deadlines.

Claimants usually need to notify Acas before making a claim. Taking part in early conciliation is voluntary. Timely notification can pause the limitation clock; pursuing an internal grievance or appeal does not. Check the official calculation rules and get advice on an individual deadline rather than assuming six calendar months is the final filing date.

How does this relate to other employment-law changes?

The tribunal filing period and the qualifying service for ordinary unfair dismissal are different rules. Government employer guidance puts the reduction in the ordinary unfair-dismissal qualifying period from two years to six months at 1 January 2027, for dismissals from that date. It did not take effect in July 2026.

This concerns eligible employees, not a new universal day-one right for all workers. Existing protections against discrimination and automatically unfair dismissal remain distinct. The same guidance confirms removal of the compensatory-award cap from 1 January 2027; it does not promise a particular award.

The separate harassment reforms are scheduled for 30 October 2026, rather than 1 October. See the Acas overview of Employment Rights Act changes for the distinction between tribunal time limits and other reforms.

What do the tribunal workload figures show?

The Ministry of Justice's April–June 2026 statistics report 14,000 new single claims during that quarter. The 70,000 figure was the outstanding single-claim caseload at the end of June. Total open single and multiple claims were 537,000 at that date. These are different measures; none is a current count of newly filed claims.

What should employers review?

1. Brief the people handling disputes. Distinguish the event date, claim type, qualifying service and filing deadline. Refer individual deadline questions for appropriate advice.
2. Keep usable records. Record reasons for decisions, relevant correspondence, meetings and appeals while events are fresh. Follow the Acas disciplinary and grievance Code.
3. Review retention by record type. Consider the purpose, relevant legal duties and disputes. The time-limit change does not create a universal two-year or three-year retention rule for all HR information. The ICO's employment-record guidance explains how to justify retention.
4. Check access and responsibility. Make sure the appropriate people can locate records securely and know who will respond to a dispute.

These are practical preparation steps, not a new blanket documentation deadline or a guarantee of a tribunal outcome.
