UK employment law: what's changing and when

Every Employment Rights Act 2025 reform and adjacent UK employment-law change on one page, with confirmed dates where they exist, and who handles it if you hire through Teamed.
The Employment Rights Act 2025 received Royal Assent on 18 December 2025 and is commencing in stages through 2027. As of 28 October 2026, measures already in force include trade union reforms, day-one family leave, Statutory Sick Pay reform, electronic trade union balloting and, since 1 October 2026, a six-month time limit for employment tribunal claims. The strengthened harassment duties start on 30 October 2026, a date fixed in law by SI 2026/1065. The biggest wave is 1 January 2027 (unfair dismissal reform); fire-and-rehire restrictions moved to March 2027 in the government's timeline update of 22 October 2026. Of the measures still without a fixed date, the timeline puts bereavement leave in April 2027 and flexible working reform in October 2027, while guaranteed hours has no stated timing.

How to read this
Status reflects whether a measure is already in force, has a confirmed commencement date, has only an expected timeframe, or is still under consultation. Commencement dates for the Employment Rights Act 2025 have moved before, most recently in a revised roadmap, so this page is reviewed regularly and figures are checked against primary sources on the dates shown.
Every one of these changes lands on your contracts, policies or payroll eventually. When Teamed is your legal employer, we track the roadmap and update what you need, when it actually commences, so a slipping date is never your problem to catch.
