FAQs

Frequently asked questions

Do fire alarm systems need to be serviced regularly?+

Yes. BS 5839-1 recommends servicing at least every six months, and more frequently for higher-risk premises. Regular servicing is also a legal requirement under the Regulatory Reform (Fire Safety) Order 2005.

What happens during a fire alarm maintenance visit?+

Our engineer tests a proportion of detectors and call points, checks sounders, batteries and the control panel, updates your logbook and issues a service certificate. Any faults found are reported clearly.

How long does a maintenance visit take?+

Most routine visits take between 60 and 120 minutes, depending on the size and complexity of your system.

What if a fault is found during maintenance?+

Faults are diagnosed on site and repaired immediately where possible. If parts are required, we explain the issue clearly before any further work is agreed.

Can you take over maintenance from another provider?+

Absolutely. We begin with a full system health check to establish its condition, then take over your servicing schedule seamlessly.
