The Workplace (Health, Safety and Welfare) Regulations 1992 oblige employers to provide workplace lighting that is "suitable and sufficient", which should be natural light, so far is "reasonably practicable".

No regulations exist that prescribe lighting levels in the workplace. The regulations do not define what is "suitable and sufficient" so to provide guidance the Chartered Institute of Building Services Engineers, CIBSE, provide a SLL LIGHTING GUIDE 7: Office Lighting which gives lighting requirements for office area. This is also replicated in BS EN 12464-1:2002 Light and lighting - Lighting of work places - Part 1: Indoor work places.

In section 5.3 of the british standard document, it provides a very thorough and detailed list of the recommended lighting levels in many different industries and locations. We have summarised a few of the more relevant suggestions

 

Area Illuminance (lux)
Circulation areas and corridors 100
Circulation areas with stairs or similar 150
Canteens and other busy areas 200
Exercise areas 300
General office space, rooms for medical attention 500
Detailed work such as the drawing offices 750
Very detailed work such as quality control 1000
Fine work or colour matching 1000 +
