Quick answer
Assess whether people can see the task, hazards and routes clearly in the conditions they actually work in. Correct poor visibility, glare and defects through suitable design and maintenance. General lighting and emergency lighting need coordinated but distinct checks.
Why a bright room can still have unsafe lighting
The GB workplace framework requires suitable and sufficient lighting. HSE’s workplace welfare ACOP explains task visibility, movement and the use of natural light so far as reasonably practicable. A room can look bright overall while a work surface, staircase or loading point remains poorly lit.
Consider the person, task and surroundings together. Reflections can obscure a screen; a worker’s body can cast a shadow across a cutting surface; changing daylight can make a previously usable desk uncomfortable. Check actual working positions rather than judging the room from the doorway.
Inspect during representative tasks and working hours
| Location or task | What to observe | Useful action to investigate |
|---|---|---|
| Detailed work and labels | Whether information and hazards are visible without awkward posture | Suitable task lighting and work-position changes |
| Screens and shiny surfaces | Reflections, glare and changing daylight | Reposition equipment and review blinds or light distribution |
| Steps, corridors and outside routes | Dark patches, abrupt changes and failed lamps | Improve coverage and prioritise defects affecting safe movement |
| Store rooms and automatic lighting | Whether people can see before entering and while remaining still | Review controls and timing for the way the area is used |
| Cleaning and maintenance | Dirty fittings, damaged covers and difficult access | Plan suitable competent maintenance with safe access |
Ask workers about headaches, difficulty seeing or tasks they avoid in poor light. Record the situation and investigate it without treating a symptom report as a diagnosis. Include early, late and night work where relevant.
Trial the improvement at the actual work position
For example, a packing bench has a new overhead fitting, but the shelf above the bench creates a shadow over labels. A suitable task-lighting solution is assessed with workers using the bench. The check includes glare, safe positioning, cleaning needs and whether any new cable creates another hazard.
In an office, coordinate the review with HSE’s workstation assessment guidance. A brighter fitting alone may worsen screen reflections. Use a competent lighting assessment when the task, environment or unresolved problem requires it; do not treat one generic lux figure as a universal legal answer for every workplace.
Give defects an owner, priority and completion check. Staff should report failed or flickering lights rather than attempting electrical repair or unsafe access themselves.
Keep failure scenarios and national scope visible
The workplace ACOP also addresses appropriate emergency lighting where failure of ordinary lighting would expose people to danger. An ordinary lighting inspection does not replace the assessment, testing and maintenance needed for the emergency system and applicable fire arrangements.
Ask what happens if the area loses its normal light: can people stop the task and reach safety? Feed that information into the appropriate emergency and fire review. Avoid relying on a phone torch as the workplace’s planned lighting solution.
The legal ACOP reference here is GB-specific. For NI workplaces check HSENI’s welfare guidance and the corresponding NI requirements, including the relevant fire framework.

Does replacing every lamp with a brighter one resolve the assessment?
No. Distribution, glare, shadows, task position and controls can matter as much as brightness. Recheck the work after the change and confirm that it has not introduced a new problem.
Next steps
Choose one poorly lit task or route, observe it during normal use and record the proposed improvement. Recheck visibility and any new hazards after the work is complete.
