Emergency Lighting System Maintenance Checklist

Keep escape routes lit when the power fails — monthly function tests, the annual full-duration test, battery and luminaire checks, and log book records to BS 5266.

What is an emergency lighting maintenance checklist?

A emergency lighting system maintenance checklist is a structured list of the 10 preventive maintenance tasks — covering visual, functional, cleaning and record-keeping checks — that keep an emergency lighting system running safely and reliably. It groups routine checks by frequency, from daily inspections to annual servicing, so FM teams and building engineers can plan and evidence preventive maintenance.

Core emergency lighting checks

  • Confirm each luminaire illuminates on test and the healthy charge LED is lit
  • Carry out a monthly short-duration function test of all luminaires and exit signs
  • Clean luminaire diffusers and exit sign legends for clear output
  • Record monthly and annual tests, failures, and remedial actions in the log book

What is an emergency lighting system?

An emergency lighting system illuminates escape routes and key safety equipment if the normal supply fails. It comprises self-contained luminaires with their own batteries or a central battery system feeding maintained and non-maintained fittings, plus illuminated exit signs. UK systems are designed and maintained to BS 5266-1. Compliance requires a brief monthly function test and a full-rated-duration test annually (typically three hours), both recorded in a log book. The fire risk assessment determines which areas require coverage.

Typical Emergency Lighting maintenance checklist

A practical starting point for planned preventive maintenance. Always refer to the manufacturer's O&M manual and site-specific requirements.

Visual Checks

  • Confirm each luminaire illuminates on test and the healthy charge LED is lit
  • Check exit signs are correctly positioned, illuminated, and unobstructed
  • Inspect batteries for swelling, leakage, or end-of-life indicators
  • Confirm coverage still matches escape routes after any layout or partition changes

Functional Checks

  • Carry out a monthly short-duration function test of all luminaires and exit signs
  • Carry out the annual full-rated-duration test (typically 3 hours)
  • Verify luminaires remain lit for the full rated duration without dropping out
  • Check central battery system charger, alarms, and standby capacity (if fitted)

Cleaning & Housekeeping

  • Clean luminaire diffusers and exit sign legends for clear output

Record Keeping

  • Record monthly and annual tests, failures, and remedial actions in the log book

Typical maintenance frequency

Suggested intervals for emergency lighting system maintenance. Actual frequencies should follow manufacturer guidance and site-specific risk assessments.

Monthly

  • Short function test of all luminaires
  • Confirm exit signs illuminate
  • Log the test

Annually

  • Full 3-hour duration test
  • Battery condition assessment
  • Coverage review against escape routes
  • Issue test certificate

Common faults and issues

Issues to be aware of when maintaining emergency lighting system equipment.

Batteries failing to hold the full three-hour duration as they age past 4 years
Luminaires removed or relocated during fit-out leaving gaps in escape route coverage
Exit signs obscured by signage, stock, or new partitions
Monthly test not carried out or logged — a frequent fire risk assessment finding
Charge LED not checked, so a failed luminaire goes unnoticed until the annual test
Full duration test run during occupied hours leaving routes unprotected while batteries recharge

Safety and compliance notes

Key safety considerations for emergency lighting system maintenance. This is general guidance only — always follow OEM instructions, statutory requirements, and your organisation's safe systems of work.

Run the annual full-duration test when the building can be safely evacuated if needed, and allow batteries to recharge fully afterwards
Do not leave the building occupied with depleted emergency lighting batteries after a duration test
Any change to layout, partitions, or escape routes requires a coverage reassessment
Faulty luminaires on escape routes must be treated as a priority repair
Keep the log book current — it is required evidence under the fire risk assessment
