Upcoming employment law changes 2025–2027: What UK employers need to know

SECTION GUIDE

Introduction

The Employment Rights Bill 2025 (ERB) represents the most sweeping package of employment law changes in decades. Once the Bill gains Royal Assent in autumn 2025, reforms will roll out across three years.
From unfair dismissal and sick pay to harassment prevention and union law, employers will need to adapt quickly. Below we’ve summarised the key changes, with references to the proposed legislation where possible.

    Public sector outsourcing protections

    • A new statutory “two-tier code” will be introduced to prevent worse terms and conditions for staff transferred out of the public sector.
  • 2027: Final Phase of Reforms

    • Following their voluntary introduction in 2026, these will become mandatory reporting obligations under the ERB.

    Collective redundancy thresholds widened

    • Amendments to TULRCA will require employers to consider redundancy numbers across the whole organisation, not just individual workplaces.

    Further trade union protections

    • Additional reforms will extend anti-blacklisting protections and modernise the UK’s industrial relations framework.

    • The ERB will expand the definition of “agency” in the Employment Agencies Act 1973 to include umbrella companies, bringing them into the enforcement regime.
