# UK third-party harassment employer liability > Live situation record from CLSTR: https://clstr.news/situations/uk-third-party-harassment-employer-liability > Updated: 2026-10-21T05:15:00.000Z. Sources: 4. Developments: 2. New regulations under the Employment Rights Act 2025 are set to take effect on October 30, 2026, expanding the liability of UK employers. Under these laws, businesses must take ‘all reasonable steps’ to prevent employees from being harassed by third parties, including customers, clients, contractors, or members of the public. Legal experts and the Equality and Human Rights Commission (EHRC) indicate that mere written policies or training may be insufficient to meet these new preventative duties. Instead, employers may need to implement formal risk assessments and proactive measures to protect staff from behavior that violates dignity or creates a hostile environment. The regulatory shift follows a significant increase in discrimination-related tribunal claims, which rose by 59% year-on-year between October and December 2025. Failure to comply with the new standards may result in employment tribunals and legal action by the EHRC, carrying both financial and reputational risks. ## Timeline ### 2026-10-21: UK employers face new third-party harassment liability UK businesses will face new legal liability for third-party harassment of staff starting 30 October 2026, requiring proactive risk assessments and preventative measures. 2 sources. https://clstr.news/cluster/uk-employers-face-new-third-party-harassment-liability ### 2026-10-14: UK employers warned of new third-party harassment liability UK employers must comply with new third-party harassment laws by October 30, taking proactive steps to protect staff from harassment by customers, clients, or the public to avoid legal action. 2 sources. https://clstr.news/cluster/uk-employers-warned-of-new-third-party-harassment-liability --- Cite as: UK third-party harassment employer liability.
