Emergency escape lighting helps people leave a building safely if normal lighting fails during a fire, power cut or other emergency. It supports safe evacuation by illuminating escape routes, exits, stairways, changes in level and key fire safety points when visibility may be reduced.
Quick Answer: When Is Emergency Escape Lighting Needed?
Emergency escape lighting is needed where people could be at risk if normal lighting fails during a fire, power cut or evacuation. Whether it is required depends on the fire risk assessment, building layout, occupancy, escape routes and use of the premises. Systems should be tested and maintained, with records kept in the fire safety logbook.
What Is Emergency Escape Lighting?
Emergency escape lighting is lighting that operates automatically when normal lighting fails, allowing people to safely move along escape routes and reach a place of safety.
Its primary purposes are to:
- Illuminate escape routes and exits
- Highlight changes in level, direction, or hazards
- Make fire safety equipment visible
- Reduce panic and confusion during evacuation
Emergency escape lighting is particularly important where buildings are occupied by people unfamiliar with the layout or where evacuation may occur in reduced visibility conditions, such as smoke or power failure.
When Is Emergency Escape Lighting Needed?
Emergency escape lighting may be needed where people could be at risk if normal lighting fails. This is especially relevant in premises with internal escape routes, staircases, windowless areas, basements, public access, sleeping accommodation, complex layouts or out-of-hours use.
Under the Regulatory Reform (Fire Safety) Order 2005, the Responsible Person must provide appropriate fire safety measures to support safe evacuation. Emergency escape lighting should therefore be considered as part of the fire risk assessment, rather than treated as a one-size-fits-all requirement.
Government guidance expects emergency lighting where escape routes are complex, unfamiliar, used outside daylight hours, or where people may need assistance to evacuate. The exact provision should reflect the premises, the evacuation strategy and the risks identified.
Design Standards and Best Practice
Emergency escape lighting systems in the UK are commonly designed, installed, and maintained in accordance with BS 5266-1.
While British Standards are not law, BS 5266-1 is widely recognised as best practice and is frequently used by enforcing authorities to judge whether emergency lighting arrangements are appropriate and defensible.
BS 5266-1 provides guidance on:
- Lighting levels along escape routes
- Locations where emergency lighting should be provided
- System types and duration
- Testing and maintenance expectations
Where Emergency Escape Lighting Is Typically Required
Emergency escape lighting is normally provided along escape routes and in areas where failure of normal lighting would increase risk, including:
- Escape routes, corridors, and stairways
- Changes in floor level or direction
- Final exits and external escape routes
- Fire alarm call points
- Fire-fighting equipment
- Windowless rooms and enclosed spaces
- Large open areas and circulation spaces
- Intersections of corridors and escape routes
Not every area requires a dedicated emergency luminaire. However, all parts of the escape route must be adequately illuminated to allow safe use.
Borrowed lighting is rarely sufficient on its own and should only be relied upon where it can be demonstrated, through risk assessment, that it provides consistent and adequate illumination during evacuation.
UK government guidance on emergency lighting explains that emergency escape lighting should be provided where the absence of normal lighting would create a risk during evacuation, particularly where escape routes are complex or unfamiliar.
Types of Emergency Escape Lighting
Emergency escape lighting systems generally fall into two main categories:
Maintained Emergency Lighting
- Remains illuminated at all times
- Common in public buildings, entertainment venues, and areas where normal lighting may be dimmed
Non-Maintained Emergency Lighting
- Operates only when normal lighting fails
- Common in workplaces and general circulation areas
Emergency lighting units are typically designed to operate for one to three hours, with three-hour duration being the most widely used, as it provides resilience during extended evacuations or power outages.
Systems may be:
- Stand-alone self-contained luminaires
- Integrated into normal lighting fittings
- Powered by central battery systems or generators
Emergency Escape Lighting and Wayfinding
Emergency escape lighting may be supplemented by wayfinding measures to support evacuation, particularly in complex or multi-storey buildings.
These may include:
- Internally illuminated exit signs
- Low-level or path-guidance lighting
- Highlighted stair nosings and handrails
Such measures can be particularly helpful where visibility may be reduced by smoke or where occupants are unfamiliar with the premises.
Special Considerations for Stairways and Changes in Level
Stairways and changes in level present a higher risk during evacuation and must be adequately illuminated.
Emergency escape lighting should ensure that:
- Each flight of stairs receives sufficient illumination
- Changes in level are clearly visible
- Handrails and landings are identifiable
Highlighting stair nosings or edges may be appropriate where lighting alone is insufficient.
Emergency Lighting Testing and Records
Emergency lighting should be checked, tested and maintained so that it remains available when needed. Records should be kept with the premises fire safety logbook and reviewed during fire risk assessment updates.
| Check | Typical record |
|---|---|
| Routine visual checks | Obvious defects, damaged fittings, missing signs, charging indicators or reported faults. |
| Monthly functional test | Short test confirming emergency lights operate when the normal lighting supply is interrupted. |
| Annual duration test | Full-rated duration test by a competent person, with faults, remedial actions and completion evidence recorded. |

Role of the Fire Risk Assessment
The need for emergency escape lighting, its type, extent, and positioning must always be determined through a fire risk assessment.
A suitable and sufficient fire risk assessment will consider:
- Building layout and complexity
- Occupancy type and familiarity
- Likelihood of lighting failure
- Evacuation routes and strategies
Emergency escape lighting should never be installed, removed, or modified without reference to the fire risk assessment and its findings.
Need Emergency Lighting Reviewed?
If your fire risk assessment has raised emergency lighting issues, your records are incomplete, or you are unsure whether your escape routes are adequately covered, Fire Risk Assessment Network can help arrange suitable fire safety support.
Conclusion
Emergency escape lighting is a fundamental life-safety measure that supports safe evacuation when normal lighting fails. It must be appropriate to the building, informed by a suitable and sufficient fire risk assessment, and maintained so it will operate when needed.
When correctly designed and managed, emergency escape lighting reduces risk, supports compliance, and helps protect occupants during an emergency.

Frequently Asked Questions
Are emergency escape lights a legal requirement?
Emergency escape lighting is required where failure of normal lighting would present a risk to people evacuating the premises. Under the Regulatory Reform (Fire Safety) Order 2005, the Responsible Person must provide appropriate fire safety measures, which may include emergency escape lighting where necessary to ensure safe evacuation.
What is the purpose of emergency escape lighting?
The purpose of emergency escape lighting is to illuminate escape routes, exits, and key fire safety equipment if normal lighting fails. This helps reduce confusion, prevent injury, and support safe evacuation during a fire or other emergency.
Where is emergency escape lighting usually required?
Emergency escape lighting is typically provided along escape routes, stairways, corridors, final exits, changes in level, fire alarm call points, fire-fighting equipment, windowless rooms, and external escape routes where lighting failure would increase risk.
Does every building need emergency escape lighting?
Not every building requires emergency escape lighting in all areas. The need for emergency lighting depends on the building layout, occupancy, complexity, and risk profile. This should always be determined through a suitable and sufficient fire risk assessment.
What is the difference between maintained and non-maintained emergency lighting?
Maintained emergency lighting remains illuminated at all times and is commonly used where normal lighting may be dimmed. Non-maintained emergency lighting only operates when normal lighting fails and is commonly used in workplaces and circulation areas.
How long should emergency escape lighting operate for?
Emergency escape lighting systems are typically designed to operate for between one and three hours. Three-hour duration systems are the most common, as they provide greater resilience during extended evacuations or power failures.
Do emergency escape lights need to be tested and maintained?
Yes. Emergency escape lighting must be regularly tested and maintained to ensure it will operate correctly in an emergency. Testing and maintenance should follow recognised guidance such as BS 5266-1, and records should be kept as part of fire safety management.
Can photo-luminescent signs replace emergency escape lighting?
No. Photo-luminescent signs may be used as a supplementary measure but must not be relied upon as a substitute for emergency escape lighting where such lighting is required.
Who is responsible for emergency escape lighting?
The Responsible Person under the Regulatory Reform (Fire Safety) Order 2005 is legally responsible. This may be an employer, building owner, landlord, managing agent, or organisation with control of the premises. Responsibility cannot be delegated away.
Is emergency escape lighting assessed as part of a fire risk assessment?
Yes. The need for emergency escape lighting, its type, extent, and positioning must be determined through a suitable and sufficient fire risk assessment. Emergency lighting should always reflect the findings of that assessment.
