Employment Rights Act 2025 Doubles Tribunal Claim Window to 6 Months as Backlogs Stretch to 2029

Summary
From Oct. 1, 2026, most UK Employment Tribunal claims — including unfair dismissal, discrimination and whistleblowing — can be filed within six months instead of three.
A 40% rise in Acas Early Conciliation receipts between July 2023 and September 2025, alongside a doubled 12-week conciliation period and more AI-driven disputes, has added pressure to a system already listing complex cases into 2029 and beyond.
For employers, the longer timeline means disputes can stay live for months before a claim is issued, increasing the risk that records degrade, witnesses leave and memories fade before hearings begin.
The reform is meant to improve access to justice and reduce protective filings, but it also raises the importance of early investigations, stronger document retention and contemporaneous decision records.
