Common questions

Emergency Lighting Testing in London — FAQ

What's the difference between monthly and annual tests?

Monthly is a brief function check; the annual test verifies full duration under simulated mains failure — both are required.

How long does the annual test take?

The building needs to run on emergency lighting for the full rated duration, typically 1–3 hours depending on system size.

Do you test battery-backed exit signs too?

Yes, all emergency luminaires on the escape route plan are included.

Questions from London clients

Frequently asked questions

How often must emergency lighting be tested in London?

BS 5266-1:2025 requires a short monthly function test of every fitting and a full rated-duration test (usually three hours) every year, with all results recorded in the logbook.

Who can carry out the annual test?

The annual duration test should be carried out by a competent person. We test outside trading hours where needed because the fittings need time to recharge afterwards.

What do I receive after the test?

You receive an emergency lighting certificate, an updated logbook and a list of failed fittings or batteries with a fixed remedial quotation.

Are you NICEIC approved?

Yes. Polarity Electrics London Ltd is an NICEIC Approved Contractor (#602034000).
