Emergency Lighting
Servicing & Maintenance
Emergency lighting is one of those systems you only notice when it fails — usually at the worst possible time. In a power cut, fire alarm activation, or smoky escape route, emergency lights guide people to safety, reduce panic, and help staff manage an evacuation safely.
In the UK, emergency lighting should be designed, installed, and maintained in line with BS 5266-1 (Emergency lighting – Code of practice for the emergency lighting of premises). For most businesses, staying compliant isn’t complicated, but it does rely on two things: regular testing and a maintenance programme that’s actually followed.
We provide professional emergency lighting servicing and maintenance delivered by ICEL Accredited Competent Engineers, covering design, installation, inspection, certification and ongoing support.
Your responsibilities as the building user
Emergency lighting is a life safety system, so the dutyholder (often the Responsible Person, landlord, facilities manager or managing agent) needs to make sure routine checks are completed and recorded.
BS 5266-1 expects that:
Regular functional checks are carried out (to confirm the fittings operate on emergency mode)
A full rated-duration test is completed (commonly a 3-hour discharge test for most systems)
Results are recorded in an emergency lighting logbook, including defects and remedial actions
Faults are acted on quickly so the system is always ready
What should emergency lighting cover?
Emergency lighting isn’t only about “a few green exit signs”. BS 5266-1 expects suitable provision for:
Final exits and exit doors used in an emergency
Escape routes and corridors, including changes of direction
Stairs and level changes
Open areas (anti-panic lighting) where people need to orientate themselves and find routes out
High-risk task areas, where work processes need to be safely shut down (for example machinery operations)
Locations of fire fighting equipment (such as extinguishers and hose reels)
Locations of fire alarm call points
Areas containing electrical switchgear, plant rooms and control panels, where safe isolation or shutdown might be required during an incident
If your building layout changes, your use changes, or new equipment/processes are introduced, coverage should be reviewed.
What happens during an emergency lighting service visit?
A proper service visit is more than a quick look to see if lights are “on”.
During our inspection and maintenance visit, we typically:
Carry out a visual inspection of fittings, diffusers, lenses, signs and mountings
Confirm the correct type of fitting is installed in the correct location for the risk
Check charging indicators and (where accessible) examine battery and internal components for deterioration or overheating signs
Test the full system to confirm the lights switch to emergency mode and remain lit, and work after their test.
Complete the partial or full duration discharge test where scheduled, then confirm recharge and correct restoration
Identify failed lamps, dim output, poor spacing, damaged signs, missing legends, or fittings obstructed by storage/stock
Update your logbook and provide service certification / reporting with defects and recommended actions
We’ll also highlight any trends — for example repeated failures in a zone that suggest age-related battery decline or poor environmental conditions.
Why emergency lighting maintenance matters
Emergency lighting is a consumable system.
Even if it looks fine day-to-day, performance can drop off quietly over time.
Battery life (often around 5 years)
Most emergency light batteries have an expected service life of around 5 years, but this varies with temperature, charge cycles, fitting quality and environment.
A system may still “switch on” during a quick test but fail to achieve the required duration when fully discharged. Battery deterioration is one of the most common reasons emergency lights fail a 3-hour test.
Lamp and LED output deterioration
Light sources degrade. Older fluorescent-based emergency fittings and even LEDs can become dimmer over time, which affects compliance with required illuminance levels on escape routes and in key areas.
Dust and debris build-up
Warehouses, workshops, plant rooms, kitchens, and even offices can accumulate dust that reduces light output and can affect heat dissipation.
Part of good maintenance is cleaning lenses, diffusers and signage so the system performs as designed.
Emergency lighting risk assessment and building changes
Emergency lighting isn’t “fit and forget”. If anything changes in the building, the emergency lighting provision may no longer be suitable.
A review (or an emergency lighting risk assessment) is particularly important when:
Escape routes are altered (new partitions, doors, changes to corridors)
The building is extended or refurbished
Storage racking is installed or moved
A space changes use (e.g., office becomes a workshop or treatment room)
Higher-risk activities are introduced (machinery, welding, heat processes)
Occupancy patterns change (evening use, sleeping risk, public events)
A short review can prevent a situation where the system is maintained perfectly — but no longer matches the premises risk.
One-off visits vs compliance through a maintenance contract
We can carry out one-off inspections, fault investigations, and certification — especially useful if you’ve taken over a building, had failures during testing, or you’re preparing for an audit.
However, ongoing compliance is achieved through a maintenance contract, because emergency lighting needs consistent testing, documentation, and timely repairs. It can easily be combined with our fire alarm servicing visits.
A planned contract keeps you on schedule, reduces disruption, and gives you a clean compliance trail for internal governance, insurers, and enforcing authorities.
Book emergency lighting servicing and certification
If you’re unsure when your last full duration test was completed, you’ve got fittings failing, or you’re concerned your system no longer reflects the building layout, we can help you get it back to a reliable, compliant standard.
Get in touch to arrange a one-off visit, an emergency lighting risk assessment or set up a maintenance contract.
How often does emergency lighting need servicing and testing?
BS 5266-1 expects routine user testing and periodic inspection by a competent person.
In practice, most premises complete weekly functional tests and an annual full rated-duration test (commonly a 3-hour discharge test) by an engineer, with results recorded in a logbook.
What’s included in an emergency lighting service visit?
A service visit typically includes a visual inspection of fittings and signs, checks of charging indicators and (where accessible) batteries, functional testing to confirm changeover to emergency mode and back, and scheduled full-duration discharge testing.
You’ll receive updated logbook entries and a service report identifying any defects and remedial actions.
How long do emergency light batteries last?
As a rule of thumb, emergency lighting batteries often have a life expectancy of around 5 years, but this varies with temperature, usage, fitting quality and environment.
Batteries can “appear” to work during short tests yet fail a full duration test as they age.
Why do emergency lights fail even when they look fine day-to-day?
Common causes include battery deterioration, reduced lamp/LED output over time, damaged diffusers, and dust or debris reducing light output.
Regular cleaning and proper testing are essential to prove the system will perform during an actual power failure.
When should we review or carry out an emergency lighting risk assessment?
Any time the building changes — new layouts, partitions, racking, changes in use, new processes, or altered escape routes — your emergency lighting provision may need reviewing.
This includes ensuring coverage for exits, escape routes, high-risk task areas, fire fighting equipment points, and plant rooms/control gear locations.
