Good lighting in the workplace is about more than just visibility!
it's a legal requirement, a key to employee wellbeing, and essential for productivity. Poor lighting can cause discomfort, eye strain, and even trigger health conditions such as migraines or light sensitivity.
Here’s everything UK employers need to know about lighting obligations under current legislation, the benefits of getting it right, and what to do if your office lights are already installed but causing discomfort.
✅ Legal Responsibilities Under UK Law
Under the Workplace (Health, Safety and Welfare) Regulations 1992, employers must ensure that lighting is “suitable and sufficient” and that “undue glare” is avoided.
Additionally, the Equality Act 2010 requires that employers make reasonable adjustments for employees with health conditions or disabilities — including those with photosensitivity, migraines, or sensory processing issues. Inappropriate lighting that causes discomfort could lead to non-compliance if reasonable changes are not made.
💡 Why Good Lighting Benefits Everyone
Reduces fatigue and headaches — Adjustable, glare-free lighting helps prevent eye strain and improves overall comfort.
Boosts productivity — Well-lit spaces have been linked to higher concentration and reduced error rates.
Supports wellbeing — Employees feel better in comfortable environments, and good lighting plays a key role in mental alertness and mood.
Saves energy — Dimmable LED panels reduce energy use, especially when paired with smart controls or daylight sensors.
🛠 Best Practice When Specifying New Office Lighting
If you're upgrading or refitting lighting in your office, consider the following recommendations:
Install dimmable LED panels
Choose panels with 0–10V, TRIAC or DALI-compatible drivers that allow adjustable brightness. This gives flexibility for different tasks and reduces glare.
Include darker or low-light areas
Create designated spaces with lower lighting levels for employees who are light-sensitive. These can serve as quiet breakout zones or flexible desks.
Use colours and textures to absorb light
Avoid white walls and desks that reflect harsh light. Instead, opt for mid-tone paint colours, soft furnishings, acoustic panels, or textured surfaces to minimise glare.
Apply window tinting or solar films
Natural daylight can worsen glare. Tinted films on windows reduce excessive brightness without blocking the benefits of natural light.
😣 Already Installed Bright Lighting? Here’s What You Can Do
If you already have fixed LED panels that are too bright and not adjustable, you can still make cost-effective changes to improve comfort and protect employee wellbeing:
1. On Desks and Workstations
Anti-glare desk mats — Placing non-reflective mats on glossy or white desks will reduce reflected light and visual discomfort.
Light Shields and screen filters — These reduce brightness from both artificial light and nearby windows.
2. At the Light Source
Apply light-dimming film — These adhesive films stick directly to the LED panel diffuser and reduce light output by 15–30% per layer. Multiple layers can be added for further reduction.
Clip-on diffusers or louvres — These help spread light more evenly and cut harsh glare.
3. In the Room Layout
Reposition desks and screens so they are not directly under or facing harsh lighting.
Use freestanding partitions or soft-finish furniture to break up reflective areas and provide visual relief.
4. Medium-Term Upgrades
Replace LED drivers with dimmable versions — In many cases, the light fitting itself is fine and only the driver needs replacing to allow dimming.
Introduce task lighting — Reduce overhead lighting and allow individuals to control their own lighting levels at their desk with desk lamps.
📝 Practical Tips for Facilities & HR Teams
Carry out a lighting survey to identify glare hotspots or areas where brightness can be reduced.
Use a simple lux meter to check light levels — general office spaces should aim for around 300–500 lux at desk height.
Include lighting preferences and sensitivities in your staff wellbeing assessments or access needs forms.
Make sure lighting is part of your organisation’s disability and accessibility policy in line with the Equality Act.
