Understanding the Employment Rights Act 

Widespread change is on the horizon. 

The Employment Rights Bill received Royal Assent on 18 December 2025, becoming an Act of Parliament (Employment Rights Act).  

Reforms are set to roll out in phases across 2026 and 2027, with the first set of changes happening throughout February and April. 

While the phased approach aims to minimise the burden placed on employers, immediate action and preparation are required to ensure compliance.

The measures will be implemented on a phased basis, with the majority of changes being brought into force on 6 April 2026, with further updates on 1 October 2026.  

Additional changes are currently subject to consultation and are expected to follow in 2027.
