UK Unfair Dismissal Rights

Alex By Alex · 12-year UK recruiter · Updated April 2026

Unfair dismissal is one of the most-litigated UK employment areas because employers often get the process wrong even when they have a fair reason. After 12 years working with both sides, I can tell you that most successful unfair dismissal claims are won on procedure failures rather than the underlying reason. The candidates who succeed are the ones who document everything during the dismissal process and act within the 3-month time limit.

The statutory floor

Five fair reasons for dismissal under UK law: capability (performance or health), conduct (behaviour at work), redundancy, statutory restriction (where employing you would breach the law), or 'some other substantial reason'. Even with a fair reason, the employer must follow a fair process — usually based on the Acas Code of Practice. Two years of continuous service typically required to claim unfair dismissal, but some grounds have no qualifying period (whistleblowing, discrimination, pregnancy-related, asserting a statutory right). Compensation: basic award (similar to statutory redundancy), compensatory award (capped at lower of 12 months' pay or £105,707 in 2024-25 for unfair dismissal), discrimination awards (uncapped).

What employers often add

Settlement agreements are how most unfair dismissal cases resolve in the UK — typically before tribunal. Employers offer a payment in exchange for the employee agreeing not to pursue a claim. Settlement amounts vary widely but typical patterns: 3-6 months' salary at mid-career, 6-12 months at senior, plus reference letter, accrued holiday, and PILON. The first £30,000 of an ex-gratia settlement payment is tax-free. Settlement agreements require independent legal advice — employer usually pays £500-£1,500 toward this.

What to do if there's a dispute

  1. 1 Document the dismissal — keep dated copies of all communications, meeting notes, performance reviews
  2. 2 Contact Acas for early conciliation — mandatory before any tribunal claim
  3. 3 Take legal advice from a specialist employment solicitor (often free initial consultation)
  4. 4 Consider whether the dismissal might be 'automatically unfair' — these have no 2-year service requirement
  5. 5 Act within 3 months minus 1 day of the effective date of dismissal — strict time limit

Red flags that should worry you

  • !Dismissal during or shortly after asserting a statutory right (whistleblowing, raising health and safety concerns)
  • !Dismissal during pregnancy or maternity leave
  • !Dismissal without a hearing or appeal opportunity
  • !Dismissal followed by your role being filled with someone matching protected characteristics differently to yours
