Lighting risks in restaurants and commercial kitchens
- Cuts and burns where prep benches and cooking lines are shadowed by canopies, shelving or the chef's own body.
- Food safety errors: misread labels and date codes, undercooked food, and missed dirt or residue during cleaning.
- Slips on wet or greasy floors that are hard to see in dim wash-up and store areas.
- Grease and heat damage to luminaires, so output falls quickly and canopy lights fail.
- Dining room trips on steps, raised areas and changes in floor level under low atmosphere lighting.
Standards and lux values
Retained food hygiene law (Regulation (EC) No 852/2004 as it applies in the UK) requires food premises to have adequate lighting. For staff, regulation 8 of the Workplace (Health, Safety and Welfare) Regulations 1992 and HSE guidance HSG38 apply. BS EN 12464-1:2021 is the recognised benchmark.
| Area (BS EN 12464-1:2021) | Maintained illuminance |
|---|---|
| Kitchen | 500 lx |
| Cashier desk | 300 lx |
| Buffet | 300 lx |
| Self-service restaurant | 200 lx |
| Store rooms | 100 lx |
| Restaurant and dining areas | Designed for atmosphere |
The kitchen value comes with colour rendering of Ra 80 or better, so food colour and doneness can be judged correctly, and a glare limit to stop bright fittings reflecting off stainless steel. Wash-up and prep areas should be assessed as part of the kitchen rather than as stores. Dining rooms have no fixed figure, but steps and routes must stay visible, and lighting must be raised enough for cleaning and closing down safely.
Who asks about restaurant lighting
Environmental health officers
EHOs inspect restaurants under the Food Hygiene Rating Scheme in England and Wales. The structural compliance element of the score covers the condition of the premises, including lighting, alongside cleanliness, layout and ventilation. Poor kitchen lighting can count against the rating, and it makes cleaning harder to do and harder to demonstrate. EHOs also enforce health and safety in most restaurants.
Licensing
Restaurants that serve alcohol or late-night refreshment hold premises licences under the Licensing Act 2003, which can include lighting conditions for public areas and external spaces. A lux survey supports new applications, variations and reviews.
Fire safety, landlords and insurers
The Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment and adequate emergency lighting. BS EN 1838:2024 sets a minimum of 1 lx along escape route centre lines and 0.5 lx in open areas such as dining rooms. Landlords and insurers may also request evidence after an incident or at lease events.
What we measure in a restaurant survey
- Prep benches, cooking lines and pass, measured at worktop height.
- Under-canopy readings, noting failed or grease-coated canopy lights.
- Wash-up, dry stores, walk-in chillers and freezers.
- Bar back and cashier positions.
- Dining room steps, ramps and level changes, with atmosphere lighting set as in service.
- Escape routes, open-area emergency lighting and exit signs.
- External seating, entrances and bin stores where they are used after dark.
We work around service, usually between lunch and dinner or before opening, and follow your kitchen hygiene rules.
Quick wins in kitchens
Degreasing canopy lights and diffusers, replacing failed lamps and adding under-shelf task lighting over prep benches often brings a kitchen up to 500 lux without a redesign. If your kitchen has been reconfigured, check that new equipment and shelving have not created shadowed work positions. Our common lighting failures guide covers other quick fixes.
Dark kitchens and small sites
Delivery-only dark kitchens and small takeaways often occupy converted industrial units or basements with little or no daylight. Lighting installed for a previous use is rarely suitable for food preparation, and multiple operators may share a single unit with partitions that block light. A survey at fit-out confirms each kitchen meets 500 lux at the working surface before the first EHO visit, and gives you evidence to put on file. The same applies to pop-ups and seasonal sites where temporary lighting has been installed quickly.
Book a restaurant or kitchen survey
We survey restaurants, cafés, pubs and dark kitchens across London and the South East. Commercial kitchen surveys start from £140 and premises licensing surveys from £160, with prices confirmed before booking. See our commercial lux surveys and emergency lighting checks, or book a kitchen survey before your next inspection.
Frequently asked questions
What lux level is required in a commercial kitchen?
BS EN 12464-1:2021 recommends 500 lux maintained illuminance for kitchens, with colour rendering of Ra 80 or better. UK food hygiene law requires adequate lighting, and this standard is the usual benchmark.
Does kitchen lighting affect my food hygiene rating?
It can. The structural compliance part of a Food Hygiene Rating Scheme inspection covers the condition of the premises, including lighting, and poor lighting also makes effective cleaning harder.
Is there a minimum lux level for a restaurant dining room?
BS EN 12464-1:2021 treats dining rooms as atmosphere spaces without a fixed value. Steps and routes must still be visible, emergency lighting must meet BS EN 1838:2024 and any licence conditions must be met.
