Does My Business Need Emergency Lighting? UK Requirements Explained

If the normal lighting in your workplace suddenly failed, could employees, customers or visitors still find their way safely out of the building?

That is the basic purpose of emergency lighting. It provides illumination when the normal lighting supply fails, helping people identify escape routes, changes in level, exits, fire safety equipment and other important points on the way to safety.

For many businesses, emergency lighting is not simply a useful backup. It forms part of the fire safety measures required for the premises. However, exactly what is needed depends on the building, how it is used and the findings of its fire risk assessment.

Portcullis Power Solutions provides electrical compliance testing across Cheshire, including emergency lighting inspections and testing for commercial and industrial premises.

Is Emergency Lighting a Legal Requirement for UK Businesses?

In many commercial and non-domestic premises, yes.

Under UK fire safety requirements, the person responsible for a business or other non-domestic premises must assess fire risks and put appropriate fire safety measures in place.

Government guidance states that a fire safety and evacuation plan must consider emergency lighting where it is needed. More detailed government guidance explains that where escape routes and exits require artificial illumination, adequate emergency lighting must be provided where necessary.

You can read the official GOV.UK guidance on workplace fire safety and evacuation plans.

That does not mean every business needs exactly the same number or type of emergency lights. The requirements should be determined by the premises and its fire risk assessment.

Who Is Responsible for Emergency Lighting?

Fire safety law refers to the person with responsibility for the premises as the responsible person.

Depending on the circumstances, this can include:

• An employer
• A business owner
• A landlord
• An occupier
• A facilities or building manager
• Another person who has control of the premises

Where responsibility is shared between several people or organisations, they need to cooperate to ensure the relevant fire safety responsibilities are met.

For a typical small business, this means emergency lighting should not simply be assumed to be the landlord’s problem or something that was dealt with when the building was originally fitted out. The current responsible person needs to make sure appropriate measures remain in place and are maintained.

What Does Emergency Lighting Actually Do?

Emergency lighting is designed to operate when the normal lighting supply fails.

During a fire or power failure, a familiar workplace can become surprisingly difficult to navigate. Smoke may reduce visibility, people may be unfamiliar with the building and the loss of normal lighting can make stairs, corridors and changes in floor level considerably more hazardous.

Emergency escape lighting helps people move towards a place of safety rather than leaving them dependent on the normal lighting system.

It can also help make important fire safety equipment and alarm points visible during an emergency.

Where Does Emergency Lighting Need to Be Installed?

The exact layout should be determined for the individual building, but government fire safety guidance identifies a number of locations that may need to be covered by an emergency escape lighting system.

These commonly include:

• Escape routes through the building
• Exit doors used during an emergency
• Corridor intersections where people need to identify the correct route
• Stairways so individual flights can be used safely
• Changes in floor level that could present a trip or fall hazard
• Outside final exits and relevant external escape routes
• Emergency escape signs
• Fire alarm call points
• Firefighting equipment
• Windowless rooms where appropriate
• Areas where equipment needs to be shut down safely during an emergency
• Larger open areas where normal lighting failure could leave occupants without adequate illumination

This does not necessarily mean a separate emergency light is required directly beside every item. The system needs to provide sufficient illumination for relevant routes, hazards, signs and equipment to remain visible and usable.

Does a Small Shop or Office Need Emergency Lighting?

Being a small business does not automatically exempt a premises from emergency lighting requirements.

There are circumstances where a very small premises may not require a dedicated emergency lighting system, particularly where there is sufficient reliable illumination from another source. However, this should not simply be assumed because a building is small.

A small shop, for example, may still have a rear stockroom, staff area, internal corridor or toilet with no useful natural light. A first-floor office may rely on an internal staircase to reach the final exit. In either situation, losing the normal lighting could create a significant problem during an evacuation.

The decision therefore needs to be based on the fire risk assessment and actual escape route, not simply the floor area or number of employees.

What About Warehouses and Industrial Premises?

Emergency lighting can be particularly important in warehouses, workshops and industrial buildings.

These premises may contain large open spaces, racking, machinery, separate work areas, loading areas and long routes to final exits. Some areas may receive little or no natural light even during normal working hours.

Industrial environments can also contain equipment or processes that need to be shut down safely during an emergency.

Portcullis Power Solutions provides commercial and industrial electrical services for businesses, including electrical installations, maintenance, compliance testing and system upgrades.

What Is Maintained Emergency Lighting?

Not every emergency light operates in exactly the same way.

Maintained emergency lighting is illuminated during normal operation and remains illuminated if the normal electrical supply fails.

Non-maintained emergency lighting normally remains off and switches on automatically when the normal lighting supply fails.

Which arrangement is appropriate depends on the premises and how the area is used. Certain venues and public-facing environments may require a different approach from a straightforward office or warehouse.

The system should therefore be specified around the building rather than simply choosing emergency light fittings and installing them wherever there is available wall or ceiling space.

Are Illuminated Fire Exit Signs the Same as Emergency Lighting?

They are closely related, but they should not simply be treated as interchangeable.

An illuminated exit sign helps occupants identify an escape route or final exit. Emergency escape lighting provides the illumination needed to travel along that route safely if the normal lighting fails.

Depending on the premises, an emergency lighting system may therefore include illuminated signs as well as emergency luminaires positioned around escape routes, stairs, exits and other important areas.

The important question is not simply whether there is a green exit sign above the door. It is whether someone can safely get from their location in the building to that exit if the normal lights go out.

What Standard Applies to Emergency Lighting?

Emergency lighting systems are covered by recognised British and European standards, including BS 5266 and BS EN 50172.

The Health and Safety Executive lists BS 5266 and BS EN 50172 among the standards relating to emergency lighting.

These standards help establish how emergency lighting systems should be designed, installed and maintained. The correct application depends on the premises, its use and the relevant fire safety requirements.

Does Emergency Lighting Need to Be Tested?

Yes. Installing emergency lighting and then forgetting about it defeats the purpose of having the system.

Emergency lighting depends on components such as batteries, luminaires, charging systems and electrical supplies continuing to operate correctly. A fitting can appear perfectly normal from the outside while failing to provide the required illumination when the mains supply is interrupted.

GOV.UK workplace fire safety guidance specifically states that regular checks should be carried out to make sure emergency lighting is working and that faults in fire safety systems and equipment are recorded.

Portcullis provides emergency lighting testing and electrical compliance services for commercial and industrial premises, with appropriate documentation provided on completion.

How Often Should Emergency Lighting Be Tested?

Emergency lighting systems require regular checking and periodic testing rather than waiting for a power cut to discover whether they work.

Different tests serve different purposes. Routine checks can identify obvious faults or failed indicators, while more comprehensive testing confirms that the system can continue operating for its required duration.

The testing regime for your premises should follow the relevant standards, the system manufacturer’s requirements and the fire safety arrangements for the building.

Businesses should also keep appropriate records of testing, maintenance and any faults or remedial work identified.

What Happens if an Emergency Light Fails a Test?

A failed emergency light should not simply be ignored until the next scheduled inspection.

The cause may be relatively straightforward, such as a failed battery or light source, but it can also indicate a problem with the charging circuit, electrical supply or the fitting itself.

Where a failed fitting affects an escape route or another important location, remedial work should be arranged so that the emergency lighting provision remains effective.

Repeated failures may also indicate that older equipment is reaching the end of its useful life and that replacing individual components is becoming less practical than upgrading part of the system.

Do I Need Emergency Lighting After Changing My Premises?

This is an important point that businesses can easily overlook.

An emergency lighting system may have been appropriate when it was originally installed, but the building may no longer have the same layout or use.

For example, you may have:

• Added partition walls or created new offices
• Changed the route employees use to reach an exit
• Converted storage space into working areas
• Installed new machinery or racking
• Changed the location of fire safety equipment
• Added or altered stairways and corridors
• Changed the number of people using the premises
• Taken over neighbouring commercial space

Changes like these can affect the original fire risk assessment and the suitability of the existing emergency lighting.

If your premises has changed significantly, it is sensible to review the fire risk assessment and consider whether the emergency lighting still covers the correct areas.

What If I’ve Just Taken Over a Commercial Property?

Do not assume that an existing emergency lighting system is automatically compliant simply because lights and exit signs are already installed.

Before relying on the system, it is worth establishing:

• When it was last professionally inspected
• Whether regular tests have been recorded
• Whether all emergency fittings operate correctly
• Whether the layout has changed since the system was designed
• Whether escape routes are adequately covered
• Whether previous faults have been rectified
• Whether appropriate certification and maintenance records are available

This is particularly important when moving into older commercial premises where several different tenants may have altered the internal layout over time.

Emergency Lighting and Your Fire Alarm System

Emergency lighting and fire alarms perform different jobs, but both contribute to safe evacuation.

The fire alarm warns occupants that they need to act. Emergency lighting helps them see how to get out if the normal lighting is unavailable.

A fire safety review should therefore consider the complete evacuation process rather than treating each system in isolation.

If your fire detection also needs reviewing, Portcullis provides fire alarm installation and maintenance for commercial premises across Cheshire.

Common Emergency Lighting Problems to Look Out For

You do not need to wait for a complete system failure before taking action. Warning signs can include:

• Emergency fittings that do not illuminate during a test
• Damaged or missing exit signs
• Warning indicators showing a fault
• Lights that operate initially but fail quickly
• Older fittings with deteriorating batteries
• Escape routes that have changed but the lighting has not
• New partitions blocking illumination from existing fittings
• Dark areas around stairs, corridors or final exits
• No recent testing or maintenance records

If you are unsure when the system was last inspected, arranging a proper emergency lighting check is considerably better than discovering a problem during an actual power failure or emergency.

Quick Emergency Lighting Checklist for Business Owners

If you are responsible for a commercial property, ask yourself:

• Has the premises got a current fire risk assessment?
• Does the escape route depend on artificial lighting?
• Are stairs, corridors and final exits adequately illuminated during a power failure?
• Can fire exit signs still be identified if the normal lighting fails?
• Are fire alarm call points and firefighting equipment visible?
• Has the emergency lighting been tested recently?
• Are testing and maintenance records available?
• Have alterations been made since the system was installed?
• Have any failed fittings or faults been left unresolved?

If you cannot confidently answer those questions, it is worth having the emergency lighting inspected.
