What Are the Regulations for Emergency Lighting in the UK?

Emergency lighting regulations in the UK are in place to ensure that people can safely evacuate a building if the normal lighting fails due to an emergency.  These regulations apply to the majority of non domestic premises such as offices, warehouses, schools, and other public buildings.

The main UK standard governing emergency lighting is BS 5266 which is supported by fire safety legislation such as the Regulatory Reform (Fire Safety) Order 2005.  These rules place responsibility on building owners; employers, landlords, and anyone else that could be defined as “responsible persons” to ensure suitable emergency lighting is installed, maintained, and tested properly in these public buildings.

What Is Emergency Lighting?

Emergency lighting is a backup lighting system that is designed to automatically turn on when the normal mains power supply fails.

Its purpose is to:

• illuminate escape routes,
• help occupants evacuate safely,
• identify fire fighting equipment,
• highlight emergency exits,
• reduce panic during emergency situations.

Emergency lighting systems usually contain rechargeable batteries that power the lights automatically during a power outage.

What are the Regulations Apply to Emergency Lighting in the UK?

Regulatory Reform (Fire Safety) Order 2005

This is the primary fire safety legislation in England and Wales.  It requires the “responsible person” for a building to carry out fire risk assessments, make sure appropriate emergency procedures are put in place and to ensure adequate emergency lighting within the necessary areas.

BS 5266 – The Main Emergency Lighting Standard

BS 5266 is the regulation for British Standard which covers emergency lighting design; installation, testing, and maintenance.  It is widely recognised as the benchmark for compliance in UK buildings for emergency lighting.

BS 5266 provides guidance on:

• where emergency lighting should be installed,
• minimum light levels,
• testing requirements,
• system duration,
• maintenance procedures.

Where Is Emergency Lighting Required?

Emergency lighting is usually required in:

• escape routes,
• stairwells,
• corridors,
• fire exit routes,
• open areas,
• high risk task areas,
• locations where occupants may be unfamiliar with the building.
• changes in floor level,
• intersections in corridors,
• toilets larger than 8m²,
• plant rooms,
• lift lobbies,
• areas housing fire safety equipment.

The exact requirements will depend on the building’s fire risk assessment.  Once this has been done you should have clear advice on where emergency lighting must be installed.

Minimum Emergency Lighting Duration

In most non domestic premises emergency lighting systems are required to operate for three hours after mains power failure.  This ensures that occupants can evacuate safely and that any emergency services required will have visibility.  

One hour systems may still be acceptable in certain low risk buildings where immediate evacuation occurs but three hour duration systems are considered to be the best practice.

Minimum Light Levels

BS 5266 and EN 1838 also specify minimum illumination requirements.  Some examples of this would be at least 1 lux along escape route centre lines and 0.5 lux in open anti panic areas.  Emergency exit signs and fire safety equipment must also remain clearly visible during power failure.  

Emergency Lighting Testing Requirements

Emergency lighting systems must be tested regularly to ensure they will work during an emergency.  A short functional test should be done once a month to confirm that the lights operate correctly and a yearly test should be done to ensure the system operates for the full duration.  This should be a full discharge test and you will need to confirm that the system lasts for the full 1-3 hours depending on the building's requirements.

Record Keeping Requirements

Building owners or responsible persons should keep a record of the below:

• testing records,
• maintenance logs,
• inspection reports,
• and repair documentation.

You may be asked to provide these records during fire inspections; insurance assessments and any investigations that occur following an incident.

Who Is Responsible for Compliance?

The “responsible person” referred to within emergency lighting and fire legislation may include:

• employers,
• landlords,
• facilities managers,
• building owners,
• managing agents.

They are responsible for ensuring that the emergency lighting is suitably maintained, regularly tested, and compliant with current regulations.

What Happens If The Emergency Lighting Is Non-Compliant?

Failure to comply with emergency lighting regulations can result in enforcement notices, prosecution, problems getting insurance, fines and a risk of increased liability following accidents or fire incidents.

Most importantly inadequate emergency lighting can put occupants at serious risk during evacuation.

Summary

Emergency lighting regulations in the UK are primarily governed by the Regulatory Reform (Fire Safety) Order 2005 and the BS 5266 British standard.  These regulations ensure buildings remain safely illuminated during emergencies and power failures so occupants can evacuate quickly and safely when needed.

The majority of public buildings that these legislations apply to will require emergency lighting systems to illuminate escape routes, operate for at least three hours, undergo regular testing and for to be properly maintained and documented.
