If you’ve been treated unfairly at work, an employment tribunal is where you can seek justice. Here’s how the process works.

What Is an Employment Tribunal?

Note on upcoming changes: The Employment Rights Act 2025 is being introduced in phases through 2026 and 2027. As of September 2026, the standard 2-year unfair dismissal qualifying period and 3-month tribunal time limit are both still current law. The qualifying period for unfair dismissal is due to fall to 6 months (with the compensatory award cap removed) for dismissals from 1 January 2027, and an extension of the standard tribunal time limit to 6 months is expected no earlier than October 2026. Check gov.uk or ACAS for confirmation before relying on either change.

Compensation

Unfair Dismissal

ComponentHow it’s calculated
Basic awardSame formula as statutory redundancy: age factor × years of service × weekly pay (capped at £751/week, 2026/27, max 20 years)
Compensatory awardActual financial loss — lost earnings, loss of pension, loss of statutory rights. Capped at £123,543 or 52 weeks’ gross pay (whichever is lower), for dismissals from 6 April 2026
Maximum basic award£22,530 (2026/27)
ReductionsTribunal can reduce for contributory fault (e.g. you were partly to blame)

The Employment Rights Act 2025 is due to remove the compensatory award cap entirely for dismissals from 1 January 2027 — this guide reflects the position up to that date.
