TLDR: Unfair dismissal after six months from January 2027

From 1 January 2027, the Employment Rights Act 2025 cuts the qualifying period for ordinary unfair dismissal from two years to six months — and removes the cap on the compensatory award, currently the lower of 52 weeks’ pay or £123,543.

  • Anyone who started on or before 1 July 2026 is protected from 1 January 2027.
  • What counts is the effective date of termination, so notice can carry a dismissal into the new rules.
  • Day one protections, such as discrimination, are unchanged.

What to do now: hire carefully, shorten probation and review people well before six months, put contracts and disciplinary and capability procedures in writing, and record every performance conversation. A tribunal can add up to 25 per cent to awards where the Acas Code was not followed. General information only — take specialist advice on a specific case.

Client Testimonial

“Having seen John of Legacy Wills present at a property event, it was clear he had both the breadth of knowledge and experience and also the ability to make a very dry subject both understandable and engaging. That’s a tough call when talking about Wills, Trusts and death. John produced Wills and POA’s for myself and my wife in a timely, effective and reasonable manner. I have subsequently recommended him to numerous colleagues and friends to cut out the jargon and challenges surrounding this critical protection, which is too often deferred or neglected.”
