BS EN 12464-1

Lux Lighting Level Testing

Measured lux readings across your workspace, confirming lighting meets the recommended level for the task being carried out — and that escape routes meet minimum illuminance.

What lux testing measures

Lux measures how much light actually falls on a surface — a desk, a workbench, a warehouse floor, an escape route. BS EN 12464-1 sets recommended lux levels for different tasks and areas: a stairwell needs far less than a fine assembly bench, and both need less than a surgical work area. We take readings with a calibrated lux meter at working height across the space and compare them to the level required for that use.

Tell us the space and what it's used for and we'll confirm a fixed price before booking — often combined with an emergency lighting visit.

Where it's requested

  • Workplace lighting audits — offices, warehouses, workshops
  • Escape route illuminance, alongside emergency lighting testing
  • Disputes over inadequate lighting raised by staff or a union
  • Fit-out sign-off, confirming installed lighting meets design spec
  • Retail and hospitality, where task lighting affects both safety and presentation

How the survey is carried out

We take a grid of readings across the relevant area at the height the task is performed — desk height for office work, floor level for escape routes — and record results against the recommended lux level for that use. Where readings fall short, we can advise on fitting positions, lamp output or additional fixtures to close the gap.

What you receive

A lux survey report showing measured readings against the relevant recommended level for each area, with any shortfalls flagged and practical remediation options.

Frequently asked questions

What's a typical recommended lux level for office work?

General office tasks are commonly recommended in the region of 300–500 lux at the working plane, though the exact figure depends on the specific task — BS EN 12464-1 sets different levels for different activities, and we confirm the correct target for your space before testing.

Is lux testing the same as emergency lighting testing?

No, but they're closely related. Emergency lighting testing (BS 5266-1) checks that lighting switches on and lasts long enough during a power failure; lux testing confirms the actual light level achieved meets the minimum needed on the escape route or task area. We often carry out both in the same visit.

Can lux testing help resolve a workplace lighting complaint?

Yes — an independent, measured lux survey gives an objective reading against the recognised standard, which is often exactly what's needed to resolve a dispute over whether lighting in a work area is adequate.
