Emergency Lighting Maintenance Checklist: Monthly & Annual

A failed emergency light during a power cut or fire isn't just an inconvenience, it's a serious safety hazard that can put lives at risk. Yet many building owners and managers overlook routine checks until an inspection flags a problem. Having a clear emergency lighting maintenance checklist helps you stay on top of both monthly and annual testing requirements, so your system works exactly when it matters most.

UK regulations, including BS 5266-1, set out specific obligations for how often emergency lighting must be tested and what each test should involve. Whether you're a landlord, facilities manager, or business owner, understanding these duties is essential to keeping your building compliant and your occupants safe.

At Electrical Testing London, we carry out emergency lighting testing across London and the South East for commercial and residential properties. This guide breaks down every step you need to follow, from quick monthly function checks to full annual duration tests, so you can maintain a reliable system year-round or know exactly what to expect when you bring in a qualified engineer.

What emergency lighting is and what UK rules require

Emergency lighting is any dedicated lighting system that activates automatically when the mains power supply fails. Unlike standard lighting, it runs on a self-contained battery or backup power source, giving occupants enough light to evacuate a building safely along designated escape routes. You'll find emergency luminaires above fire exits, in stairwells, and in corridors, but they only do their job if the batteries and bulbs are in working order.

The two main types of emergency lighting

Most buildings use one of two types: maintained luminaires, which stay on continuously and switch to battery when the mains fails, and non-maintained luminaires, which only illuminate during a power cut. Your building type and use will determine which category applies. A busy commercial office, for example, typically requires maintained fittings, while a residential property might use non-maintained units in communal areas.

The type of emergency lighting you install or inherit affects how you test it, so confirm which system you have before you follow any checklist.

What the UK regulations actually say

BS 5266-1:2016 is the British Standard that governs emergency lighting in non-domestic premises, and it sets out your testing, recording, and maintenance obligations in detail. The Regulatory Reform (Fire Safety) Order 2005 also places a legal duty on the "responsible person" for a premises to ensure escape routes are adequately lit at all times. Together, these mean that letting your emergency lighting system sit untested is not just poor practice; it exposes you to enforcement action, insurance complications, and real risk to life. Your emergency lighting maintenance checklist needs to reflect both the monthly functional test and the annual full-duration test that these standards require.

Step 1. Prepare your site and logbook

Before you run any test, you need two things in place: a physical walk of your site to locate every emergency luminaire, and an up-to-date log book to record your findings. Without both, you have no baseline and no evidence of compliance if an inspector visits.

What your logbook must include

Your logbook is the [central record](https://www.electricaltestinglondon.co.uk/blog/emergency-lighting-log-book-requirements--bs-5266-1-rules) for your emergency lighting maintenance checklist and should capture every test, fault, and repair. Keep it on-site or in a secure digital format that your team can access at any time.

A missing or incomplete logbook is one of the most common reasons buildings fail fire safety inspections, even when the lights themselves are working correctly.

Label each fitting with a unique reference number before your first test so you can track individual units consistently across all future records.

Step 2. Run the monthly functional test

The monthly functional test checks that each emergency luminaire activates correctly when the mains supply is cut. This test should take no longer than a few minutes per fitting and forms the most frequent entry in your emergency lighting maintenance checklist.

How to carry out the monthly test

Use the key switch or test facility on each luminaire (or your central testing panel if you have one) to simulate a mains failure. Hold the test long enough to confirm the lamp illuminates, then restore the mains supply and check the charging indicator returns to normal.

Never leave a battery-powered luminaire discharged for longer than the manufacturer's recommended test period, as this shortens battery life.

Work through every fitting using this sequence:

1. Trigger the test mode on the luminaire or panel
2. Confirm the lamp lights up within 5 seconds
3. Check the light output covers the intended escape route
4. Restore the mains supply
5. Verify the charge indicator is active after restoration
6. Log the pass or fail result against the fitting's reference number in your logbook

Step 3. Run the annual full-duration test

The annual full-duration test runs each luminaire on battery power for a full three hours (or the rated duration for the fitting), proving that batteries hold sufficient charge to sustain lighting during a prolonged emergency. This is the most demanding entry on your emergency lighting maintenance checklist and requires careful scheduling to avoid disrupting building occupants.

How to conduct the full-duration test

Choose a time when the building is unoccupied or when occupants have been briefed, since the test cuts mains power to the emergency circuit for the full duration. Work through each luminaire using this sequence:

1. Record the start time and date in your logbook
2. Activate the test mode or isolate the mains circuit supplying the emergency lighting
3. Confirm every luminaire illuminates immediately and stays lit
4. At the three-hour mark, check that all fittings are still lit at adequate brightness
5. Restore the mains supply and confirm charge indicators return to active within the manufacturer's stated recharge period
6. Log a pass or fail for each fitting against its reference number

Allow at least 24 hours for batteries to recharge fully before the building returns to normal operation.

Step 4. Fix faults and keep compliant records

When a luminaire fails either test, you must act on it promptly. A fault logged but left unrepaired does not protect you legally and leaves your escape routes unreliable. Your emergency lighting maintenance checklist is only useful if the remedial side gets the same attention as the testing side.

Prioritising and fixing faults

Treat every failure as urgent, not a job to schedule for next month. Replace faulty lamps or batteries within the same working week where possible, and retest the affected fitting once the repair is complete. If a fitting repeatedly fails, arrange for a qualified engineer to inspect the wiring and fitting itself, as the fault may be deeper than a worn battery.

A repaired luminaire must be retested and its result logged before you consider the fault closed.

Keeping records that satisfy inspectors

Your logbook entry for each fault should capture the fault description, the corrective action taken, the date the repair was completed, and the retest result. Use this template for each fault entry:

Quick recap and next steps

Your emergency lighting maintenance checklist covers four clear steps: prepare your site and logbook, run the monthly functional test, carry out the annual full-duration test, and fix faults with complete records. Each step builds on the last, and skipping any one of them leaves gaps that inspectors will notice and that can compromise safety in a real emergency.

Staying consistent with these checks protects your occupants, keeps you compliant with BS 5266-1 and the Regulatory Reform (Fire Safety) Order 2005, and gives you a documented history that holds up under scrutiny. The logbook and fault records you build over time are as important as the tests themselves.
