How we work
A fire alarm is only compliant if it is maintained. We service fire alarm systems across London on planned schedules — twice a year for commercial premises under BS 5839-1, annually for domestic and HMO systems under BS 5839-6 — and issue the certificate your insurer, fire risk assessor or licensing officer will ask to see. We take over systems installed by anyone.

- Cause-and-effect testing and fault log review
- Certificates issued on every visit for insurers and licensing officers

What you get from working with us
Compliance, Not Just a Visit
Every service produces a certificate and a written test record. That is what your insurer, fire risk assessor and — for HMOs — your licensing officer will actually ask to see. A service without paperwork is worth very little when someone asks for evidence.
We Never Let It Lapse
Servicing intervals slip because nobody is tracking them. We hold the schedule and contact you before each visit is due, so your certification stays continuous rather than restarting every time it is forgotten.
Takeover Without a Rip-Out
You do not need to have bought the system from us. We survey what is there, report honestly on its condition, and take it onto contract. Obsolete panels can usually be repaired or replaced individually rather than renewing the whole installation.
Faults Fixed, Not Just Logged
Beeping panel, fault light or false alarms? Our engineers are across London every day, so a fault between visits usually gets same-day attention rather than a week's wait, and we repair any make of panel.
How Often Your System Needs Servicing
Commercial premises — every 6 months
BS 5839-1 sets a minimum of two service visits a year for panel systems in offices, shops, restaurants, warehouses and industrial units. Devices are tested in rotation so that everything is covered annually, and the panel, batteries and cause-and-effect programming are checked each time.
HMOs and rented homes — annually
Grade D interlinked systems under BS 5839-6 need a professional check once a year. For licensed HMOs this certificate is normally part of what the council asks for at inspection, alongside emergency lighting and the fire risk assessment.
Blocks of flats — communal systems
Communal detection, smoke ventilation and emergency lighting in purpose-built and converted blocks are usually scheduled together. AOV systems carry their own requirement under BS 7346-8 of at least two visits a year, which is the item managing agents most often discover has been missed.
Weekly testing — your responsibility
Between our visits, the responsible person should test a different call point each week and record it in the logbook. We set this up at handover and leave the logbook ready to use — it takes about two minutes and it is the first thing a fire officer looks at.
Frequently Asked Questions
How often should a fire alarm be serviced?
BS 5839-1 recommends commercial fire alarm systems are serviced at least every six months by a competent person, split into two visits a year. Domestic and HMO systems under BS 5839-6 should be professionally checked annually. In both cases the responsible person should also carry out a weekly user test of a different call point each week.
How much does fire alarm servicing cost in London?
An annual service of a Grade D interlinked system in a domestic or HMO property typically runs £80–£150 per property, often combined with other compliance checks on the same visit to save on call-out costs. Commercial panel systems are priced by the number of zones and devices, quoted after a survey.
Can you service a system another company installed?
Yes, and it is a large part of what we do. We survey the existing installation, give you an honest condition report and a list of any remedial work needed, then take it onto a maintenance contract. There is no requirement to replace equipment that is working.
What happens during a fire alarm service visit?
We test a proportion of the detectors and call points so that every device is covered across the year, check the panel for faults, test sounders and any linked systems such as door releases or smoke vents, inspect batteries and power supplies, review the fault and event log, and complete the logbook. You receive a certificate and a written record of everything tested.
What happens if my fire alarm servicing has lapsed?
It can be brought back into date. We carry out a full inspection, identify anything that has failed since the last service, quote for the remedials and then recertify. Insurers and licensing officers generally want to see that a lapse has been corrected and a schedule resumed, rather than that it never happened.
Do you cover emergency lighting and extinguishers too?
Yes. Emergency lighting, extinguisher servicing under BS 5306 and AOV smoke ventilation under BS 7346-8 can all sit on the same schedule and the same visit, so you deal with one contractor and one set of certificates instead of three.
