A Complete Guide to Emergency Lighting Requirements for Businesses
Emergency lighting is a vital life safety system for commercial and public buildings. If normal lighting fails during a fire, power cut or emergency, emergency lighting helps people evacuate safely by illuminating escape routes, exits, stairwells, and key safety points.
Whether you manage a school, university, warehouse, factory, office, healthcare setting, hospitality venue, or multi-state estate, understanding your emergency lighting responsibilities is essential.
In this emergency lighting guide, we explain exactly what emergency lighting is, where it’s needed, how it works, and what businesses need to know when it comes to emergency lighting testing, maintenance, and compliance.
What is emergency lighting?
Emergency lighting is a backup lighting system that automatically activates when the normal mains power supply fails. It provides enough illumination to help occupants leave a building safely and allows key safety procedures to continue during an emergency.
Emergency lighting is often commonly installed across:
- Escape routes
- Corridors
- Stairwells
- Final exits
- Open areas
- Plant rooms
- High risk areas
- Places where fire safety equipment needs to be visible
Without suitable emergency lighting, a sudden loss of power could leave occupants disorientated, delay evacuation, and increase the risk of injury.
What are the current emergency lighting regulations in the UK?
Emergency lighting requirements in the UK are shaped by a combination of fire safety legislation, British Standards, and the findings of a suitable fire risk assessment.
Under Article 14 of the Regulatory Reform (Fire Safety) Order 2005, emergency routes and exits that require illumination must be provided with emergency lighting of adequate intensity if normal lighting fails.
As well as that, BS 5266 gives recommendations for the design, installation, and wiring of emergency lighting systems when normal lighting supply fails. The latest BS 5266-1 guidance aims to support a consistent approach so people can safely leave, remain in, or continue essential safety actions within a building during an emergency.
The exact level of emergency escape lighting required will depend on the size, type, and risk profile of your premises. Government fire risk assessment guidance for offices and shops also states that the complexity of emergency escape lighting will vary depending on your building and the risks to occupants.
Where should emergency lighting be installed?
Emergency lighting should be installed wherever people may need guidance or illumination if normal lighting fails. This is usually determined through your fire risk assessment and a professional system design.
Some typical areas emergency escape lighting is installed include:
- Corridors
- Escape routes
- Staircases
- Changes of direction
- Final exits
- Open areas
- Windowless rooms
- Toilets without natural light
- Basements
- Plant rooms
- Fire alarm call points
- Fire fighting equipment locations
In larger or more complex buildings, additional emergency lighting may be needed in high risk task areas, production areas, loading bays, teaching spaces, laboratories, workshops, or areas used by visitors unfamiliar with your layout.
How often should emergency lighting be tested?
Carrying out regular emergency lighting testing is essential to confirm that your system will operate correctly in an emergency. Your testing schedule should reflect your building type, system design, and fire risk assessment.
As a general guide, businesses should carry out:
- Routine visual checks – to check for damage, faults, indicator lights, or obstruction.
- Monthly functional tests – a short test to confirm fittings illuminate when mains power is interrupted.
- Annual full duration test – a full rated discharge test, usually three hours, to confirm batteries can sustain emergency operation.
It’s important to remember that all testing should be recorded, with any faults investigated and repaired promptly.
How do you test emergency lighting?
Emergency lighting should be tested carefully to ensure the system remains reliable and properly documented.
A monthly functional test usually involves:
- Simulating a mains power failure
- Checking that each emergency light activates
- Confirming that exit signs remain visible
- Recording any failed fittings or battery issues
An annual full duration test is much more detailed because it checks whether the system can remain illuminated for the required period. This should be planned carefully, as batteries need time to recharge afterwards.
For larger buildings, multi-site estates, schools, factories, and facilities managed properties, professional testing helps ensure the system is checked consistently and records are kept correctly.
Who can test emergency lighting?
Basic monthly checks can be carried out in house by a trained responsible person, such as as facilities manager, caretaker, or maintenance team member.
However, annual servicing, fault diagnosis, and full duration testing should be carried out by a competent fire safety provider, like Hoyles Fire & Safety, or a trained emergency lighting contractor. This helps ensure that testing is completed correctly, faults are identified properly, and documentation is suitable for audits, inspections, and fire risk assessment reviews.
Who is responsible for ensuring emergency lighting compliance?
Responsibility for emergency lighting compliance usually sits with the ‘Responsible Person’ as per fire safety legislation. This may be the:
- Employer
- Building owner
- Occupier
- Landlord
- Managing agent
- Anyone with control over the premises
Their responsibilities include ensuring suitable fire safety measures are in place, maintained, and reviewed. This includes emergency lighting where it’s required to support safe evacuation.
In practice, facilities managers, site managers, and health and safety teams often manage emergency lighting testing and maintenance day to day. However, the legal responsibility remains with the person or organisation in control of the premises.
What are some common emergency lighting faults found during inspections?
When we carry out emergency lighting inspections here at Hoyles Fire & Safety, there are a few common faults we often find, such as:
- Failed batteries
- Damaged fittings
- Missing test records
- Poor positioning
- Obstructured luminaires
- Outdated units
- Inadequate coverage following layout changes
These problems can reduce the effectiveness of your system and create compliance risks. For example, if a corridor layout has changed or new internal partitions have been added, the original emergency lighting design may no longer provide suitable coverage.
That’s why keeping up with regular emergency lighting maintenance is key because it helps identify these problems before they become serious safety issues.

Emergency lighting FAQs
- Why are emergency lights provided?
- Emergency lights are provided to support safe evacuation when normal lighting is no longer available. In a fire or power failure, people need to identify escape routes, follow exit signs, and move safely towards a place of safety. They’re especially important in buildings with larger floor areas, internal corridors, stairwells, limited natural light, or complex layouts. Emergency lighting also supports fire wardens, facilities teams, and emergency responders by keeping important routes and safety points visible.
- How do emergency lights work?
- Emergency lighting systems are connected to the mains power supply and include a battery backup. During normal operation, the mains supply powers the fitting and keeps the battery charged. If the mains supply fails, the emergency light automatically switches to battery power, providing temporary illumination. Some emergency lights are maintained, meaning they stay lit during normal operations and continue working during a power failure.
- How long should emergency lights last?
- Most commercial emergency lighting systems are designed to provide illumination for a rated duration, most commonly three hours. The correct duration will depend on the building, its use, and the emergency lighting design. A three hour duration is often used because it allows time for evacuation, emergency response, and possible delays before the normal lighting supply is restored.
- Why does professional emergency lighting support matter?
- Working with a professional fire safety provider, like Hoyles Fire & Safety, or an emergency lighting contractor can help ensure your system is properly designed, installed, tested, and maintained. Professional support can cover new installations, system upgrades, monthly and annual testing, fault finding, repairs, compliance reporting, and recommendations following fire risk assessments. This is particularly valuable where buildings are complex, older, recently refurbished, or used by large numbers of people.
- Can emergency lighting be added to an existing building?
- Yes, emergency lighting can usually be added, upgraded, or reconfigured in existing buildings, especially where the layout, occupancy, building use, or fire risk assessment has changed. A professional assessment can identify where lighting is required, whether existing coverage is suitable, and what improvements are needed to meet current emergency lighting requirements and relevant British Standards.
- What happens if my emergency lighting fails an inspection?
- If your emergency lighting fails an inspection, the fault should be recorded, investigated, and repaired as soon as possible. Issues such as failed batteries, damaged fittings, poor coverage, or missing test records can affect safe evacuation and may leave the building non-compliant until remedial work is completed.
