Upcoming October 2026 implementation dates for Employment Rights Act reforms
With the October 2026 implementation dates now confirmed, the Employment Rights Act 2025 is set to introduce one of the most significant overhauls of UK workplace law in recent years. Employers and HR professionals must prepare for a wave of changes taking effect on 1 October and 30 October 2026.
From 1 October 2026, the standard time limit for bringing most Employment Tribunal claims will double from three months to six months. However, transitional provisions mean this extension only applies where the relevant date—the act or failure to act complained of—occurs on or after 1 October 2026. Employment lawyers have expressed concern this change could significantly increase the current Tribunal backlog, already under substantial pressure.
The most impactful change comes on 30 October 2026, when the duty on employers to prevent sexual harassment will strengthen from taking “reasonable steps” to taking “all reasonable steps”. This means Tribunals will assess whether any further reasonable measures were available that the employer should have taken. Employers failing to meet this enhanced standard face a potential 25% compensation uplift on successful claims.
Notably, the duty will also extend to third-party harassment across all protected characteristics (except marriage and civil partnership, and pregnancy and maternity). The Equality and Human Rights Commission’s recent report highlights that workplaces remain a common setting for harassment, with financial services and hospitality sectors particularly affected. Policies alone are insufficient—they must be implemented consistently and reviewed regularly.
Several measures have experienced delays or remain subject to consultation. Tipping reforms, originally scheduled for October 2026, have been pushed back to “by the end of 2026” following union criticism of the draft Code of Practice. The regulations establishing the Fair Pay Agreement Adult Social Care Negotiating Body are expected in October, with negotiations beginning April 2027 and the first agreement introduced by April 2028.
The two-tier Code, which prevents outsourced private sector employees receiving less favourable terms than public sector transferees, will be reinstated through regulations expected in October 2026, though details remain subject to further legislation.
Meanwhile, the Fair Work Agency, established in April 2026, will enforce statutory holiday pay rights from 2027. A consultation proposes the Agency could investigate claims up to six years in the past, with penalties mirroring national minimum wage breaches—200% of arrears, up to £20,000 per worker.
Acas has also published a draft Code of Practice on disciplinary and grievance procedures for consultation, placing much greater emphasis on early, informal resolution and mediation.
With the high-profile changes to unfair dismissal rights—including reducing the qualifying period to six months and removing the compensation cap—now scheduled for 1 January 2027, employers should view October 2026 as a critical preparatory phase. The reforms demand proactive rather than reactive compliance, particularly regarding harassment prevention.
