Health assessments

Employers must offer workers a free health assessment before they become a night worker. Workers do not have to accept.

The assessment must be written by a qualified health professional. It can be a questionnaire.

Employers must take into account that night work might increase a worker’s stress levels.

The worker must get a follow-up examination by a health professional when an employer is unsure if the worker is fit for night work.

A repeat assessment must be offered regularly.

The employer must offer suitable other work where possible if a worker has health problems that a doctor says are related to night work.

Keep records

Employers must keep confidential records of:

  • the health assessments (keep for 2 years)
  • dates when assessments were offered (if a worker did not want one)
