When this tool helps

About Tribunal Deadline Calculator

ToolsWebPro Unfair Dismissal & Employment Tribunal Deadline Calculator is a free, privacy-first legal timeline utility designed for employees and employers in England, Wales, and Scotland. Enacted under the landmark Employment Rights Act 2025 and commencement regulations (SI 2026/954, SI 2026/758, SI 2026/759), the UK employment regime undergoes dual major reforms: the tribunal limitation period increases from 3 months to 6 months (less one day) for events on or after 1 October 2026, and unfair dismissal qualifying continuous service reduces from 2 years to 6 months for dismissals where the effective date of termination (EDT) is on or after 1 January 2027. This tool harmonizes both transition rules, factors in Acas Early Conciliation pause math under ERA 1996 s.207B and the binding Luton Borough Council v Haque EAT decision, applies statutory minimum notice extensions under s.97(2), and exports iCalendar (.ics) alerts with 14-day and 3-day filing reminders. Explore our detailed guides on the 6-Month Qualifying Period (1 Jan 2027) and Tribunal Time Limits & Acas Conciliation, or create custom reminders with our ICS Calendar Generator.

England, Wales & Scotland. Updated for the Employment Rights Act 2025. Work out whether you have enough service to claim unfair dismissal and calculate your tribunal claim deadline, including Acas early conciliation pause rules, statutory minimum notice extensions, and worked examples.

ToolsWebPro provides this tool free with no account required. Each tool explains its supported formats, processing limits and privacy behavior.

Frequently asked questions

How long do I have to bring an employment tribunal claim?

Most claims have six months less one day from the relevant date where it falls on or after 1 October 2026; earlier dates keep three months less one day. You must go through Acas early conciliation first.

Does the six-month limit apply to a dismissal on 30 September 2026?

No, the change is not retrospective, so three months less one day applies.

When does the unfair dismissal qualifying period drop to six months?

Where the EDT is on or after 1 January 2027. Before that, two years. Employees employed on or before 1 July 2026 will already have six months' service on 1 January 2027.

What is the effective date of termination?

With notice, the day notice expires; without notice, the day termination takes effect.

Does notice or pay in lieu change my qualifying service?

It can: the statutory minimum notice (one week in the first two years) can be added when you were dismissed without notice, except for gross misconduct.

Do I need qualifying service for discrimination or automatically unfair dismissal?

No. Claims under the Equality Act 2010 (discrimination, harassment) and automatically unfair dismissal claims (whistleblowing, health and safety, pregnancy, asserting statutory rights) are Day-1 rights with no qualifying period.

How does Acas early conciliation change my deadline?

The days between Day A and Day B stop the clock, and you always get at least one month after Day B (worked through step by step per the Luton Borough Council v Haque decision).

Do I have to contact Acas before the deadline?

Yes, Acas must be contacted within the primary limit, then you claim by the extended date.

Is the cap on unfair dismissal compensation changing?

It is due to be removed from 1 January 2027; this tool does not calculate compensation.

Does this cover Northern Ireland, and is this legal advice?

No to both. Northern Ireland operates under separate devolved legislation (Industrial Tribunals Order 1996), and this tool provides general informational guidance only, not formal legal advice. Always speak to Acas, Citizens Advice, a trade union, or an employment solicitor before relying on a date.
