Night worker health legislation

According to the Working Time Regulations 1998, a ‘night worker’ is an employee whose regular work hours includes at least three hours of the night time.

Under this legislation, night time is between 11 pm to 6 am unless otherwise agreed upon by the employer and employee.

While working at night doesn’t necessarily pose any significant health risks, it may worsen some existing health conditions including epilepsy, depression, anxiety and diabetes.

You’re required to offer all night workers health assessments. It must be free and carried out before they become night workers.

This piece explores the health assessment as well as some tips for ensuring the health and safety of your night workers.

The Health and Safety Executive (HSE) enforces the night worker health assessment requirement detailed in the Working Time Regulations 1998.

This health assessment helps employers to identify where night shifts are causing workers health risks. After completion, it also helps to decide how best to make reasonable adjustments.
