How to Choose the Right Emergency Lighting System for Your Building
Emergency lighting is one of the most important life safety systems within any commercial, industrial or public building. During a power failure or emergency, occupants rely on emergency lighting to find escape routes safely, avoid hazards and evacuate the premises efficiently.
Choosing the right emergency lighting system is not simply about installing a few illuminated fittings. Every building has different layouts, occupancy levels, risks and legal obligations, making professional design and installation essential.
At William Hale Fire & Security, we design, install, commission and maintain premium emergency lighting systems throughout the UK. Our tailored approach ensures every property receives a system designed specifically for its needs while helping clients remain compliant with current British Standards.
Why Emergency Lighting Matters
Emergency lighting provides illumination whenever the mains electrical supply fails.
This may happen because of:
- Fire
- Electrical faults
- Storm damage
- Power outages
- Planned maintenance
- Accidental cable damage
Without emergency lighting, occupants may struggle to find exits, stairs or escape routes, increasing the risk of injury and delaying evacuation.
Emergency lighting is designed to:
- Illuminate escape routes
- Highlight emergency exits
- Reduce panic
- Allow safe evacuation
- Help emergency services operate safely
- Maintain compliance with UK legislation
What Does Emergency Lighting Actually Include?
Many people assume emergency lighting only refers to illuminated exit signs.
In reality, a complete emergency lighting system includes several different components.
| Emergency Lighting Type | Purpose |
|---|---|
| Escape route lighting | Illuminates corridors and exit routes |
| Open area lighting | Prevents panic in larger spaces |
| High-risk task lighting | Allows dangerous equipment to be shut down safely |
| Exit signs | Clearly identify escape exits |
| Stairwell lighting | Illuminates changes in floor level |
| External escape lighting | Continues illumination outside final exits |
Every Building Has Different Requirements
One of the biggest mistakes property owners make is assuming every building requires the same system.
The ideal emergency lighting design depends upon numerous factors including:
- Building size
- Floor layout
- Occupancy
- Fire risk assessment
- Ceiling heights
- Available natural light
- Escape route complexity
- Working environment
For example, a warehouse has completely different requirements compared to a hotel, school or office.
Professional assessment ensures every area receives appropriate protection.
Types of Buildings That Require Emergency Lighting
Emergency lighting is required across numerous sectors.
| Building Type | Typical Requirements |
|---|---|
| Offices | Escape routes, stairwells, toilets |
| Schools | Corridors, classrooms, halls |
| Warehouses | High-risk task areas and exits |
| Retail stores | Customer escape routes |
| Hotels | Bedrooms, corridors, staircases |
| Apartment blocks | Communal escape routes |
| Care homes | Enhanced evacuation lighting |
| Factories | Machinery shutdown areas |
| Healthcare facilities | Patient evacuation routes |
| Leisure centres | Large open areas and changing facilities |
Understanding Maintained and Non-Maintained Emergency Lighting
One of the first decisions is selecting between maintained and non-maintained fittings.
Maintained Lighting
Maintained emergency lights remain illuminated all the time.
When mains power fails, they automatically switch to battery power.
These are commonly installed in:
- Theatres
- Cinemas
- Shopping centres
- Hotels
- Entertainment venues
Non-Maintained Lighting
These fittings only illuminate when mains power fails.
During normal operation they remain switched off.
They are commonly used in:
- Offices
- Industrial buildings
- Warehouses
- Plant rooms
- Storage facilities
Combined Maintained Systems
Some buildings require a mixture of both depending upon the specific area.
Professional designers calculate exactly which fittings should be installed throughout the premises.
Self-Test or Manual Testing?
Modern emergency lighting systems offer different testing options.
| Feature | Manual Testing | Self-Test System |
|---|---|---|
| Weekly checks | Manual | Automatic |
| Monthly checks | Manual | Automatic |
| Annual tests | Manual recording | Automated reports |
| Labour costs | Higher | Lower |
| Human error | Greater | Reduced |
| Compliance records | Manual logbook | Electronic records |
Self-testing systems usually cost more initially but often reduce maintenance costs over the lifetime of the installation.
LED Emergency Lighting
Older emergency lighting often used fluorescent lamps.
Modern systems almost always use LED technology.
Advantages include:
- Lower electricity consumption
- Longer lifespan
- Brighter illumination
- Reduced maintenance
- Better reliability
- Lower replacement costs
Although premium LED systems may have a higher installation cost, they generally provide better long-term value.
Battery Backup Duration
Emergency lighting operates using rechargeable batteries.
Most systems provide:
| Duration | Suitable For |
|---|---|
| 1 hour | Some low-risk applications |
| 3 hours | Most commercial buildings |
| Longer durations | Specialist environments |
Three-hour emergency lighting is the most commonly specified solution because it provides sufficient evacuation time even during prolonged power failures.
Building Layout Makes a Huge Difference
The internal layout has a significant influence on emergency lighting design.
Factors include:
- Long corridors
- Dead-end routes
- Open plan offices
- Multiple staircases
- Basement areas
- Roof access
- Lift lobbies
- Mezzanine floors
Every change in direction, level or hazard requires careful consideration.
Poorly positioned fittings can leave dangerous dark spots.
Areas That Often Require Additional Lighting
Certain locations usually require extra emergency illumination.
These include:
| Area | Reason |
|---|---|
| Staircases | Prevent falls |
| Fire alarm call points | Easy identification |
| Fire extinguishers | Quick access |
| First aid stations | Medical assistance |
| Refuge areas | Safe waiting points |
| Final exits | Safe building evacuation |
| Plant rooms | Equipment shutdown |
| Electrical switch rooms | Safe isolation procedures |
Occupancy Levels Matter
Buildings with high occupancy require particularly careful emergency lighting design.
Examples include:
- Shopping centres
- Schools
- Sports halls
- Hotels
- Restaurants
- Event venues
Higher occupant numbers often require additional fittings to maintain appropriate light levels during evacuation.
Open Areas Need Different Lighting
Large open spaces present unique challenges.
Examples include:
- Warehouses
- Reception areas
- Distribution centres
- Sports halls
- Exhibition centres
These spaces require anti-panic lighting designed to help occupants identify escape routes quickly.
High-Risk Task Areas
Some workplaces contain machinery or hazardous equipment.
Emergency lighting must allow employees to:
- Shut down machinery safely
- Isolate electrical equipment
- Stop dangerous processes
- Avoid injury during power failure
These systems often require higher illumination levels than standard escape routes.
Ceiling Height Influences Design
Higher ceilings usually require:
- More powerful fittings
- Wider beam angles
- Additional units
- Professional light level calculations
Warehouse lighting differs considerably from office lighting due to installation height.
Existing Fire Safety Systems
Emergency lighting should complement other life safety systems.
These often include:
- Fire alarms
- Smoke detection
- Fire extinguishers
- Fire doors
- Fire compartmentation
- Disabled refuge systems
- Security systems
A coordinated approach provides the highest level of protection.
Choosing Quality Over Cheap Installations
Emergency lighting is not an area where cutting costs is advisable.
Very low-cost installations may involve:
- Inferior batteries
- Poor quality fittings
- Shorter lifespan
- Reduced reliability
- Inadequate coverage
- Minimal documentation
A professionally designed premium installation often proves significantly better value over many years.
Typical Factors Affecting Installation Cost
Every project is different.
Pricing depends upon:
| Cost Factor | Effect on Price |
|---|---|
| Building size | Larger buildings require more fittings |
| Number of escape routes | More fittings needed |
| Ceiling height | Specialist access equipment may be required |
| Existing wiring | May reduce installation time |
| Testing system | Self-test systems cost more |
| Battery duration | Longer duration systems may increase costs |
| Specialist environments | Additional design requirements |
Rather than choosing the cheapest quotation, building owners should consider long-term reliability, compliance, maintenance requirements and overall quality.
Professional Design Is Essential
Emergency lighting is not simply installed wherever there is available ceiling space.
Professional designers consider:
- Escape route distances
- Light level calculations
- Beam distribution
- Uniformity
- Emergency exit visibility
- Obstructions
- Ceiling construction
- Future maintenance access
Every fitting should contribute towards a fully compliant evacuation strategy.
Ongoing Maintenance Is Equally Important
Installing emergency lighting is only the beginning.
Routine servicing helps ensure:

Emergency Lighting for Building Refurbishments
Building refurbishments provide an ideal opportunity to review and improve existing emergency lighting. Even if the original system was compliant when it was installed, changes to the building layout may mean it no longer provides adequate coverage.
Refurbishment projects that often require an emergency lighting review include:
- Office reconfigurations
- Warehouse extensions
- Retail refits
- School renovations
- Hotel refurbishments
- Factory alterations
- New partition walls
- Loft or mezzanine conversions
Adding new walls, relocating doors or changing escape routes can all affect how emergency lighting performs during an evacuation.

|---|---|
| New internal walls | May block light coverage |
| Additional offices | Extra escape routes required |
| Warehouse expansion | More fittings may be needed |
| Staircase alterations | Existing lighting may become insufficient |
| New exits | Additional exit signage required |
| Ceiling replacements | Opportunity to upgrade fittings |
Rather than attempting to adapt an outdated system, many building owners choose to install modern LED emergency lighting throughout the refurbished areas to improve reliability and reduce future maintenance.
Future-Proofing Your Emergency Lighting System
When investing in emergency lighting, it is worth considering the future needs of your building rather than only its current use.
Businesses frequently expand, reconfigure office layouts or increase occupancy over time. Choosing a flexible system can make future upgrades far simpler and more cost-effective.
Examples of future changes include:
- Additional staff
- New production areas
- Warehouse racking alterations
- Office extensions
- New meeting rooms
- Changes in building use
- Increased public access
A professionally designed system allows for expansion without needing to replace the entire installation.
Planning ahead can reduce disruption and help avoid unnecessary costs when modifications become necessary.
Common Mistakes Building Owners Make
Emergency lighting is highly specialised, yet several common mistakes continue to appear in older installations.
These include:
- Installing too few fittings
- Ignoring changes to escape routes
- Failing to replace ageing batteries
- Blocking emergency lights with shelving or equipment
- Forgetting external escape routes
- Not recording routine testing
- Assuming standard lighting is sufficient during a power failure
Even relatively small changes to a building can have a significant impact on emergency lighting effectiveness.
Regular professional inspections help identify issues before they become compliance problems.
Why Documentation Matters
A professionally installed emergency lighting system should always be supported by comprehensive documentation.
Accurate records make future maintenance much easier and demonstrate that the system has been properly commissioned.
Typical documentation may include:
| Document | Purpose |
|---|---|
| System design drawings | Shows fitting locations |
| Commissioning certificates | Confirms correct installation |
| Test records | Demonstrates ongoing maintenance |
| Maintenance schedules | Helps plan future servicing |
| Asset registers | Identifies installed equipment |
Keeping documentation organised can save considerable time during inspections, maintenance visits or future building alterations.
