When is the deadline for employment tribunal claim (unfair dismissal and most claims)?

The catalogue records a 3 months period from the effective date of termination (or the act complained of). This draft page remains free only until its source, worked example and limits are reviewed.

Source link required
This page is in preparation. It does not offer an automated deadline or a paid record until the missing source or calculator evidence is complete.

In preparation

The existing catalogue does not yet have a registered adapter or source evidence for this exact question. It remains available as a public preparation page only.

Example pending review

A separately reviewed fixture is required before this question can become indexable. The page does not present an unreviewed output as an example.

Calculation basis and source

Period
3 months
Trigger
the effective date of termination (or the act complained of)
Counting
The encoded calculator method must be independently documented before publication.
Rollovers and holidays

This route remains in preparation until a pinpoint official source is recorded.

  • ACAS early conciliation stops the clock; the maximum EC period is twelve weeks for notifications on or after 1 December 2025, with at least one month from the EC certificate to lodge. The full computation, including the extension, runs in the Employment Tribunal calculator on this site.
