Adequate indoor lighting is crucial for both health and safety, as well as the prevention of issues like Sick Building Syndrome


Employers have a duty to ensure that lighting is safe and does not pose a health risk to employees and others who may use their premises.

The Management of Health and Safety at Work Regulations 1999 (MHSW) require employers to have arrangements in place to cover health and safety. This includes lighting which needs to be suitable and adequate to meet the requirements of the Workplace Regulations 1992.

Furthermore a number of building certification organisations such as BREEAM, Fitwel, WELL and LEED offer credits for indoor environments that are fitted with optimal circadian lighting which promotes occupant health.

The quicker and easier it is to see a hazard, the more easily it is avoided. The types of hazard present at work therefore determine the lighting requirements for safe operation.

Poor lighting can not only affect the health of people at work causing symptoms like eyestrain, migraine and headaches, but it is also linked to Sick Building Syndrome in new and refurbished buildings. Symptoms of this include headaches, lethargy, irritability and poor concentration.


ActionsActions and advice

Concerning health and safety in the workplace, the primary aim of a lighting level assessment is to gauge and evaluate the illumination conditions specific to each workstation. This assessment is conducted to ensure alignment with the guidelines outlined in HSG38 in the United Kingdom, and it provides recommendations for enhancements if necessary. A comprehensive HSG38 assessment encompasses the following crucial elements:

  • Identification and management of health and safety risks associated with lighting in the workplace.
  • Best practices for lighting in the workplace.
  • Establishment of minimum recommended illumination levels to uphold health and safety standards in the work environment.

In instances where an evaluation of lighting levels is mandated for a building's indoor environment certification, the assessment should adhere to specific criteria. This includes the examination of factors such as glare, flicker, and illumination levels to meet the certification standards
