From 1 December 2025, the Acas early conciliation period for potential employment tribunal claims will double from six weeks to twelve weeks.

Why the Change Matters

The extension aims to reduce the pressure on employment tribunals and give parties more time to resolve workplace disputes through Acas before formal proceedings begin. However, both employers and employees must understand how this affects claim deadlines and conciliation strategy.

Key Implications

  • Longer resolution period: Parties will now have up to 12 weeks to attempt settlement before a tribunal claim is lodged.
  • Paused limitation periods: The early conciliation process continues to pause statutory deadlines — meaning claim time limits may be extended.
  • Greater flexibility, but longer uncertainty: Employers may face extended waiting times before knowing if a claim proceeds.

 

For Employers

  • Review your HR and dispute procedures – ensure internal grievance and disciplinary processes are clear and compliant.
  • Train HR and management – ensure they understand how Acas early conciliation works and how to respond effectively.
  • Seek early legal advice – engaging solicitors during conciliation can lead to quicker, cost-effective settlements.

 

For Employees

  • Don’t delay action – even with more time, deadlines still apply once conciliation ends.
  • Understand your rights – conciliation can be a useful step to achieve resolution without going to tribunal.
  • Get advice early – a solicitor can help you use the extra time strategically and protect your claim.
