Emergency lighting placement begins with the escape routes and hazards identified in the building's fire-risk assessment. Check exits, stairways, changes of level and direction, and the equipment people may need during evacuation. A competent designer must confirm coverage, spacing and emergency operation for the premises.
Where should emergency lighting be installed?
Check these locations against the building's escape strategy. The list identifies areas to assess; it does not determine the number or spacing of fittings.
- Exit doors, escape routes and corridor intersections.
- Stairways, changes in floor level and changes of direction.
- Final exits and external escape routes.
- Emergency escape signs, fire alarm call points and firefighting equipment.
- Windowless rooms, relevant toilet accommodation and equipment that needs safe shutdown.
The GOV.UK guide for offices and shops explains emergency escape-lighting provision. Other building uses need their relevant guidance and fire-risk assessment.
Exits, stairways and changes of direction
Route lighting and exit signs serve different purposes. A sign identifies the direction of escape; a luminaire provides light to see the route and its hazards. Check both when comparing fittings for corridors, stairs and final exits.
A drawing should show the mounting position and orientation of each luminaire. Doors, beams, bulkheads and changes of level can obstruct light or sightlines, so the actual building arrangement matters. A simple floor-area estimate cannot identify every obstruction or establish a compliant installation.
For dedicated escape lighting, compare emergency downlights with the mounting and distribution needed. Keep exit-sign mounting and visibility separate from the route-lighting calculation.
How many fittings are needed, and how far apart?
Use the exact product's emergency photometric data, mounting height and optic to calculate spacing. Normal-mode lumen output is not a substitute for emergency-mode output. The calculation must also account for the geometry of the escape route, open area or task being assessed.
There is no single spacing distance that suits every emergency luminaire. Two fittings with similar appearance can have different emergency outputs, optics and battery arrangements. Changing the mounting height or rotating an asymmetric optic can change the result.
The emergency lighting calculator provides an initial estimate. Use a competent emergency-lighting designer to confirm the final layout and the applicable performance requirements.
Maintained, non-maintained and emergency conversions
Maintained lighting has a normal-lighting function as well as an emergency function. Non-maintained lighting normally remains off and operates when the normal lighting supply fails. The required mode depends on the location, occupancy and design.
The maintained and non-maintained comparison explains those operating differences. Confirm the selected product's wiring and control instructions with the installer, including response to a local normal-lighting circuit failure.
An emergency conversion may allow a normal commercial luminaire to provide emergency light. Confirm the specific fitting, conversion gear, emergency output, battery position and access. A generic emergency option does not establish that every configuration is covered.
Choosing optics, mounting and exit signs
Compare escape-route and open-area optics using their actual emergency distribution. Narrow corridors and broader spaces can require different distributions; the product's technical information should identify the available optic and mounting choices.
Check ceiling construction, recess depth, fixing method and the space needed for batteries and control gear. Maintenance access matters when fittings are installed over stairs, in high ceilings or in areas that remain occupied.
Exit signs need the correct legend, direction, viewing distance and mounting arrangement. Confirm those choices against the escape strategy rather than selecting an arrow or mounting style from the product photograph alone.
Which UK emergency-lighting standards apply?
BS 5266-1:2025 is the current UK code of practice for emergency lighting of premises. Its revision reflects changes in EN 1838 and EN 50172.
BS EN 1838:2024 addresses lighting requirements; BS EN 50172:2024 addresses emergency escape-lighting systems. Use the applicable current documents, fire-safety duties and building-specific assessment together. A product description or a generic lux table cannot certify the installation.
Fire-safety law and guidance differ between UK jurisdictions and building uses. Confirm the requirements for the premises with the responsible project professionals.
Testing and maintenance after installation
GOV.UK guidance describes a monthly function test and an annual full-discharge test. Keep results and faults recorded, arrange remedial action and plan full-duration testing so that battery recharge does not leave occupied premises without the required protection.
Self-test and DALI-monitored products change how tests and results are managed. They do not remove the need to review faults or maintain the system. Battery replacement must follow the actual product instructions and condition, rather than a universal replacement interval.
Use the maintenance and testing planner to organise the recurring checks. Retain commissioning information, product instructions, test results and fault-resolution records for the people managing the building.
Emergency luminaire information for a quotation
Once the emergency-lighting design is defined, compare the specified luminaires by mounting, optic, emergency output, operating mode, rated duration and test arrangement. Check the exact product datasheet and configuration, including the selected battery and any conversion gear.
