Fire Alarm Fault Finding & 24/7 Call Outs in London

Rapid diagnosis and repair of fire alarm faults across London — 24 hours a day, 7 days a week, by FIA-trained engineers carrying spares for every major panel.

Fast, accurate fault diagnosis you can trust

A fault on a fire alarm system is more than an inconvenience — it leaves your property non-compliant and your occupants exposed. Guardian Fire Solutions provides 24/7 fire alarm fault finding across London, with rapid dispatch to commercial premises, residential blocks and HMOs.

Our engineers carry diagnostic equipment and a wide range of spares for Fike, Advanced, Apollo, Kentec, Honeywell and other major manufacturers, so most faults are resolved on the first visit. We trace the root cause — wiring, detectors, batteries, panel programming or environmental factors — rather than simply resetting the panel.

Every call out is documented with a clear written report and logbook entry, ready for insurers, the Responsible Person and the London Fire Brigade.
