When emergency lighting is first installed and commissioned, it is in its best condition. From that day on, batteries begin to age, fittings face knocks and wear, and the building around them changes. Without planned maintenance, a system that was fully suitable at handover can drift into a state where several lights would fail at the moment they are needed.
Emergency lighting maintenance is what stops that drift. It brings together routine checks, scheduled testing, repairs, battery and component replacement, record keeping and periodic reviews into one programme. At William Hale, we design, install and maintain emergency lighting systems for residential and commercial clients, and maintenance is the part of the job that keeps every installation dependable year after year.
This complete guide for UK businesses explains what emergency lighting maintenance covers, how to plan a programme, how to deal with faults and ageing equipment, and what to look for in a maintenance provider.
Why Emergency Lighting Maintenance Matters
Emergency lighting can save lives by helping people find safe passage out of a building during a fire or a power cut when the main lighting has failed. It only does that if it is in working order on the day.
In England and Wales, the Regulatory Reform (Fire Safety) Order 2005 places duties on the responsible person to maintain fire safety measures, including emergency lighting where it is required, in an efficient state, in efficient working order and in good repair. Scotland and Northern Ireland have their own legislation with equivalent duties.
Maintenance is therefore not an optional extra. It is part of the responsibility that comes with having emergency lighting in the first place.
What Emergency Lighting Maintenance Covers
A full maintenance programme is broader than testing alone. It usually includes:
- Routine visual checks of fittings, signs and indicators.
- Monthly functional testing to confirm lights operate on mains failure.
- Annual full-duration testing to confirm lights run for their rated duration.
- Fault investigation and repair whenever a problem is found.
- Battery and component replacement as equipment ages.
- Record keeping in a logbook.
- Periodic review of the installation against the building as it is now.
BS 5266-1, BS EN 1838 and BS EN 50172 are among the standards commonly relevant to emergency lighting design, performance, inspection and maintenance. The applicable editions and the manufacturer’s instructions should guide the programme for each installation.
Planning a Maintenance Programme
A good programme is planned rather than reactive. These steps provide a practical structure.
Step 1: Know What You Have
Start with an accurate picture of the installation. Which areas are covered? Where is every luminaire and exit sign? Is the system made up of self-contained fittings, a central battery system or a mix? Is there a commissioning certificate and a drawing?
If no drawing exists, a survey is the right first step. Where a previous contractor left no records, we survey the building, plot every existing luminaire, identify gaps against the current standard and issue a schedule showing what needs to be added and what can be retained.
Step 2: Assign Responsibilities
Decide who carries out routine checks, who reviews records and who arranges specialist work. In shared or leased buildings, write down how duties are split between landlord, tenant and any managing agent. Appointing a contractor does not automatically remove the responsible person’s own duties.
Step 3: Set the Schedule
Put monthly test dates and the annual duration test in a shared calendar. Allow time after duration tests for batteries to recharge, and plan around periods when the building is occupied. Include backup cover for holidays and absence.
Step 4: Decide How Testing Will Be Done
Monthly checks can be done manually by instructed staff or automated through self-test fittings. If monthly tests depend on someone remembering a key switch in a cupboard and keep getting missed, we recommend self-test fittings or a scheduled service visit so the routine no longer relies on goodwill.
Step 5: Arrange Specialist Support
Annual duration testing, fault diagnosis and repairs are best handled by a competent emergency lighting specialist. A clear service agreement makes it easier to track dates, manage defects and keep records consistent.
Routine Maintenance Tasks
Visual Checks
Regular visual checks pick up obvious issues between tests. Where the system has central indicators, these should be checked daily. Walk-rounds should look for:
- Damaged, loose or missing fittings.
- Cracked or damaged covers and diffusers.
- Fault indicators or units not showing they are charging.
- Exit signs that are blocked, faded or pointing the wrong way.
- Stock, furniture or displays obstructing lights.
Monthly Functional Tests
Using the designated test facility, the normal supply is briefly interrupted so the relevant emergency lights and signs can be checked. Results, including any failures and their locations, should be logged straight away.
Annual Full-Duration Tests
Once a year, the system runs on its backup supply for its full rated duration, which is three hours for many installations. This is the test that reveals batteries which have lost capacity, even if they have passed every monthly check.
Maintenance by System Type
The type of system affects how maintenance is carried out in practice.
Self-Contained Luminaires
Self-contained fittings carry their own battery, charger and control gear. They are quick to install, need no fire-rated supply cabling, and a single failure affects only one unit, which is why they are common in small and medium installations. Maintenance is spread across every fitting, because each one has its own battery to test and eventually replace.
Central Battery Systems
Central battery systems place one large battery bank in a plant room and feed every luminaire from it. Testing and battery replacement happen in one place and runtime is easier to guarantee. However, the distribution must be fire-rated, and the design is less forgiving of later changes to the building, so alterations need careful planning.
Maintained, Non-Maintained and Sustained Fittings
Maintained fittings, including most exit signs, are lit all the time. Non-maintained fittings only light on mains failure. Sustained fittings contain both a mains lamp and an emergency lamp. Each needs functional and duration testing, and knowing which type is installed helps the person maintaining it understand what to expect.
Dealing With Faults
Faults are inevitable over the life of a system. What matters is how quickly and thoroughly they are resolved.
Common Faults
| Fault | Possible cause | Typical response |
|---|---|---|
| Light does not come on during a test | Battery, lamp, charging or connection fault | Investigate and repair |
| Light fails before the end of a duration test | Deteriorated battery or charging problem | Check battery and charging circuit |
| Warning indicator stays on | System or battery fault | Follow the manufacturer’s fault-finding procedure |
| Exit sign damaged or hard to see | Impact, wear or poor positioning | Repair or replace and review position |
| Repeated failures in one area | Underlying equipment or electrical issue | Detailed technical investigation |
A Sound Repair Process
- Record the fault and its exact location.
- Assess its effect on safe evacuation.
- Put temporary precautions in place if an important route is affected.
- Repair the underlying cause rather than simply clearing a warning.
- Retest the fitting and record the result.
Urgent and Out-of-Hours Faults
Some faults cannot wait until the next working day. Our out of hours call out service provides a dedicated manned telephone line, with engineer response 24 hours a day, 365 days a year, a highly skilled and experienced engineer on call and a four-hour response time.
Batteries and Ageing Equipment
Batteries are at the heart of most emergency lighting systems, and they naturally deteriorate over time. Signs that batteries may need attention include fittings failing quickly during testing, repeated duration test failures, warning indicators and slow or incomplete charging.
Repair, Replace or Upgrade?
There is no single replacement interval for every system. Equipment life depends on design, battery type, operating conditions, maintenance history and manufacturer recommendations. Decisions should be based on condition and performance rather than age alone.
Replacement or upgrade may be the better option when:
- Batteries repeatedly fail duration tests.
- Fittings are damaged or components are no longer supported.
- The installation no longer gives suitable coverage after building changes.
- Multiple fittings across the building keep failing.
An upgrade can also be an opportunity to improve reliability and introduce newer emergency lighting technology. A professional assessment can help decide whether a system should be maintained, upgraded or replaced.
Maintenance After Building Changes
Emergency lighting positions are designed around the building’s escape strategy. When the building changes, the lighting may need to change too.
Open-plan offices that are split into smaller rooms may need extra coverage. Retail refits move partitions and displays. Warehouses that add racking may find that spacing designed for an empty floor no longer delivers the required lighting once stocked. Extensions add new escape routes.
Emergency lighting should be considered as part of any refurbishment, not after the work is finished. A review after significant changes confirms the system still covers every point of emphasis, including stair flights, changes of level, corridor junctions, changes of direction, fire alarm call points, firefighting equipment and final exits.
Minimising Disruption During Maintenance
Businesses cannot usually close a floor for maintenance or upgrade work. Duration tests also leave the emergency lighting below full capacity while batteries recharge.
For this reason, we phase work and carry it out in evenings, weekends or agreed windows where the building demands it. Testing large sites in sections can also help, so not every area is discharged at the same time.
Maintenance Records
A logbook is the backbone of a maintenance programme. It should contain:
- The commissioning certificate and installation drawings.
- Monthly test dates, results and defects.
- Annual duration test dates, durations and results.
- Faults found, repairs completed and components replaced.
- Follow-up tests confirming repairs.
- Outstanding actions and who is responsible for them.
Review the logbook periodically. Repeated failures in one area or frequent missed tests are signs that the programme needs adjusting.
Emergency Lighting as Part of Wider Fire Safety Maintenance
Emergency lighting works alongside other fire safety systems, so it makes sense to plan maintenance together. Our service maintenance packages cover fire alarm, emergency lighting, intruder alarm, VSS (CCTV) and access control systems installed by us, with our Emergency 24/7 Call Out Service included as standard.
Through our additional services, we also provide Fire Risk Assessments, dry riser maintenance, AOV maintenance and fire extinguishers, and we design, install and maintain fire detection systems.
Choosing an Emergency Lighting Maintenance Provider
When comparing providers, consider:
- Experience with emergency lighting and with premises like yours.
- Which tests and inspections are included in the service.
- The quality and clarity of records after each visit.
- How faults are reported, prioritised and repaired.
- Whether there is an out-of-hours route for urgent faults.
- Whether the provider can take over a system installed by someone else.
- Whether work can be scheduled to suit your building.

Frequently Asked Questions
What does emergency lighting maintenance include?
Visual checks, monthly functional tests, annual full-duration tests, fault repairs, battery and component replacement, record keeping and periodic review of the installation.
Can you maintain a system another company installed?
Yes. We can take over the service maintenance of existing systems, starting with a survey where no drawings or records exist.
How do I know if my emergency lighting needs upgrading?
Repeated battery failures, damaged or unsupported fittings, coverage gaps after building changes or widespread faults can all indicate that an upgrade is worth considering.
Will maintenance disrupt my business?
Work can be phased and carried out in evenings, weekends or agreed windows to keep disruption to a minimum.
What happens if a fault occurs outside office hours?
Our out of hours call out service has a dedicated manned line, engineer response 24/7, 365 days a year, and a four-hour response time.
Do self-test fittings remove the need for maintenance?
No. They can automate routine testing and record keeping, but results still need reviewing, faults still need repairing and the system still needs periodic review.
Keep Your Emergency Lighting Dependable
Emergency lighting maintenance is what keeps a system ready for the day it is needed. A planned programme, regular testing, prompt repairs, sensible decisions about ageing equipment and complete records give UK businesses confidence that escape routes will stay lit when the normal lighting fails.
