In force since 30 October 2026. Employers in England, Scotland and Wales must take all reasonable steps to prevent sexual harassment of their employees, and must not permit a third party, such as a customer, to harass them: you permit it if it happens in the course of the job and you failed to take all reasonable steps to prevent it (Employment Rights Act 2025 sections 20 to 22, brought into force by S.I. 2026/1065). The law does not list the steps, and when we checked on 28 October 2026 no regulations listing them had been made.

How we check our work

  1. Written from official sources. We read the legislation and the official guidance, link every source, and say what is law, what is guidance and what is not yet in force.
  2. Dated. Every guide shows when it was last updated and last checked, and a dated list of changes.
  3. Reviewed by a named person, only when that is true. A reviewer is named on a guide only after a person has actually reviewed it.
