How to do a monthly emergency lighting test

The monthly function test — often called a flick test — proves every emergency luminaire and exit sign comes on under battery. Keep it short, walk every fitting, and write the result down before you leave.

This is the how-to for the person on the floor. For the schedule (monthly vs annual), see how often to test emergency lighting. Not a substitute for BS 5266 or legal advice.

Before you start

You need a list of fittings you trust more than a blank corridor. Without one, you will miss a store room.

  • A living site register (the fitting list you update between visits instead of rewriting from scratch) — or at least last month’s list with locations.
  • Access to the test key, inhibit switch, or central test facility for that installation.
  • Somewhere to note failures by ID or location before you restore supply.
  • The site logbook (or digital equivalent) ready for the entry.

Step by step

  1. Simulate mains failure with the test key, inhibit switch, or central test facility — whichever that building uses. You are putting the emergency fittings onto battery, not killing the whole site’s lights unless that is how the system works.
  2. Walk the route. Check every luminaire and illuminated exit sign on the register. Do not skip plant rooms, cupboards, or late additions that never made it onto last year’s spreadsheet.
  3. Confirm each fitting lights and looks normal — not dim, flickering, or missing a head. Seconds are enough; you are proving it comes on, not running a duration test.
  4. Note failures immediately by location or fitting ID. Do not rely on memory after you restore supply.
  5. Restore mains / cancel the test. Confirm the system is back to normal operation.
  6. Record the outcome in the logbook — date, who tested, pass or failures listed, any remedial action arranged.

Keep it short

Function only

Brief flick — confirm every fitting comes on. Leave duration to the annual.

Logbook entry

Date, tester, result. Gaps between annuals are still a compliance problem.

What “pass” looks like

  • Fitting illuminates promptly when put onto battery.
  • Light looks steady and adequate for that fitting’s purpose — not obviously dim or flickering.
  • Exit signs show the legend clearly; no missing or dead sections.
  • After restore, the fitting returns to its normal (mains) state as expected.

Anything that fails gets logged and fixed. A fitting that “usually works” but failed today is a fail — record it.

What not to do

  • Do not leave fittings on battery for ages while you chat or hunt for a key. You will drain packs that need to be ready for a real emergency.
  • Do not skip rooms because they are locked or awkward. Arrange access or note the omission — an incomplete test is not a clean pass.
  • Do not treat the monthly as a three-hour duration test. That is a different job — see how to run an annual duration test.
  • Do not leave without writing it down. If it is not in the logbook, next month’s tester (and the inspector) will assume it never happened.

What to record

For a routine monthly, the logbook is usually enough. Note:

  • Date and that it was a monthly function / flick test
  • Who carried it out
  • Clear pass, or failures listed by ID / location
  • Remedial action and when it will be (or was) completed

Some clients want a visit report every month as well. Ask them. Free blank forms live on our templates page if you still work on paper.

Frequently asked questions

How long should a monthly emergency lighting test take?

Keep each fitting on battery only long enough to confirm it lights and looks normal — typically seconds, not minutes. How long the whole test takes depends on the size of the building, but you should not drain the packs.

Do I need a visit report after every monthly test?

Usually the logbook entry is enough for a routine monthly flick test. Some clients still want a visit report every time — ask them. Always record the result.

What if I find a dead fitting on the monthly test?

Note the location or fitting ID, restore supply, log the failure, and arrange remedial work. Do not leave the system on battery while you hunt for a spare.

Can Beacon record monthly flick tests?

Yes. Beacon is built for monthly function tests on the same living site register you use for the annual — the fitting list you update between visits instead of rewriting from scratch — defects stay on the fitting. Free in open beta.
