Fire alarm maintenance in London is bought as a contract and judged on two things: what it proves over a full cycle, and what it leaves for the building to do. Article 17 requires the fire safety measures to be kept in efficient working order by a suitable system of maintenance. A visit that samples a few devices and signs the log has not discharged that, whatever the invoice says.
What the contract should prove over a cycle
Every detector and call point function tested, sounders audible where the design says they must be, standby batteries tested under load, cause and effect verified so the right things happen on the right signal, and faults recorded with what was done about each. Over the cycle means every device, not a rotating sample that never completes. Ask how many visits it takes to get round the whole system once.
What stays with the responsible person
The weekly user test, the log book, and acting on what the engineer reports. Those are the building's, not the contractor's, and they are the first things an inspecting officer asks to see because they show the system is being watched between visits. A building that assumed the contract covered the weekly test can be months untested without anybody noticing.
Multi-tenant and managed buildings
A London office block or a mixed use building often has one alarm system, several occupiers and a managing agent in the middle. The contract has to say who calls the engineer, who gets the report, who pays for remedial work and who tells the tenants when the system is on test. Where that is unwritten, faults sit open because each party assumes another has it.
Comparing quotes that look the same
Put them side by side on four things: the number of visits, whether every device is proved over the cycle or only a sample, what happens to faults found on the day, and the call out response time with the rate that applies out of hours. Those four separate quotes that otherwise differ only in the headline figure.
A new fire alarm, and the four decisions before anybody quotes
Four decisions set the price and the system, and a quote given without them is a guess. The CATEGORY, which is what the system is for: life protection in the parts of a building people escape through, life protection throughout, or property protection, written as an L or a P grade with a number, and it comes from the fire risk assessment rather than from preference. Whether it is wired or wireless, which is a question about the building's fabric and the disruption you can tolerate rather than about quality. Whether it is conventional, where a zone tells you roughly where, or addressable, where each device identifies itself, which matters as soon as the building is large enough that searching a zone wastes minutes. And the interfaces, meaning door releases, dampers, plant shutdown, lift homing and any link to a monitoring centre, which are usually the part left out of the cheapest quote. Settle those four in writing and two quotes become comparable.
Questions people ask about fire alarm maintenance London
How many maintenance visits a year does a London building need?
There is no statutory number. The recognised approach spreads periodic inspection and servicing through the year rather than doing it in one sitting, and how many visits suits a building comes out of its fire risk assessment.
Is the weekly test part of the contract?
Usually not. The weekly user test is a duty holder task and the contract covers the engineer visits. Assuming otherwise is a common way for a building to go untested for months.
Who arranges maintenance in a multi-let building?
Whoever controls the system, usually the landlord or managing agent for a shared system. The contract should still name who reports faults and who authorises remedial work, because that is where the delay happens.
What does a fire alarm system inspection cover?
Function testing devices, checking the panel and its standby supply, proving cause and effect, and recording faults with what was done. Over a full cycle it should reach every device rather than a rotating sample that never completes.
