Fire Alarm Installation in West London
Fire detection and alarm systems designed, installed and commissioned for businesses and homes across Uxbridge, Hillingdon and West London, with reference to BS 5839.

Fire alarm installation for commercial and domestic premises
A fire alarm system only does its job if it is designed around the building it protects. Ignis Secure Limited surveys your premises first, then designs and installs a fire detection and alarm system that reflects the layout, the way the building is used and the findings of your fire risk assessment. We work with reference to BS 5839, the British Standard for fire detection and fire alarm systems, and we hand over the documentation you need for your own records.
We install new systems, replace ageing ones and extend existing systems when buildings change. Our clients across West London include offices, shops, restaurants, schools, warehouses, landlords with HMO properties and homeowners who want detection beyond a basic smoke alarm.

Types of fire alarm system we install
Conventional systems
A cost effective choice for smaller premises. The building is divided into zones, and the panel tells you which zone an alarm has come from. Well suited to small offices, shops and similar units.
Addressable systems
Each device has its own address, so the panel identifies the exact detector or call point that triggered. Addressable systems suit larger or more complex buildings where finding the source quickly matters, and they make fault finding and servicing faster.
Wireless systems
Radio linked devices that avoid long cable runs. Useful in finished buildings where cabling would be disruptive, in temporary setups, and in buildings where the fabric should not be disturbed.
Domestic systems
For houses, flats and HMOs we install systems with reference to BS 5839-6, which covers fire detection in dwellings, including the grades and categories typically requested by local authorities for licensed HMOs.
Who we install fire alarms for
Most of our installation work falls into a few familiar building types, each with its own requirements:
- Offices and commercial units, where the system needs to fit around working hours and existing fit outs.
- Shops and restaurants, where kitchens, storerooms and public areas each need the right type of detection.
- HMOs and rented properties, where landlords need systems that satisfy licensing conditions and keep tenants safe.
- Schools and community buildings, where phased work and clear communication around term times matter.
- Warehouses and industrial units, where high ceilings and dust call for carefully chosen detection.

Our installation process
-
Site survey
We visit your premises, look at the layout and how the building is used, and discuss what your fire risk assessment calls for. The survey is free and there is no obligation.
-
Design and quotation
You receive a written quotation with the proposed system type, device locations and costs set out clearly, so you can compare it on a like for like basis.
-
Installation
Our engineers install the system tidily and work around your hours where needed. We keep you informed as the work progresses.
-
Commissioning and handover
The system is tested, commissioned and certificated. We walk you through the panel, set up your logbook and explain the routine testing the system needs.
How much does fire alarm installation cost?
It depends on the size of the building, the category of system required and whether wired or wireless equipment is the better fit. Rather than quoting a misleading flat rate, we survey first and give you a fixed written quotation, so there are no surprises once work begins. The survey and the quotation are free.
After installation, keeping the system maintained protects both the equipment and your compliance records. We offer ongoing fire alarm maintenance and servicing, and our guide on how often a fire alarm should be serviced explains what routine testing and servicing involve.
Frequently Asked Questions
How long does a fire alarm installation take?
It depends on the size of the building and the type of system. A small office or shop can often be completed in one to two days, while larger or multi floor premises take longer. We confirm a realistic timescale in your quotation and agree working hours that suit you.
Does my business legally need a fire alarm?
In England and Wales the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person for a non domestic premises to have appropriate fire detection and warning arrangements in place. What is appropriate depends on your fire risk assessment. We can survey your premises and explain what your assessment is likely to call for, but the fire risk assessment itself remains the deciding document.
Will the installation disrupt my business?
We plan installations to keep disruption to a minimum. That can mean working outside your opening hours, phasing the work area by area, or using wireless equipment where running cables would be intrusive. We agree the approach with you before work starts.
Can you extend or take over an existing fire alarm system?
In many cases, yes. If your existing panel and devices are serviceable we can often extend the system to cover new areas, replace faulty devices or take over routine servicing. We start with an inspection of the current system and give you an honest view on whether extending it or replacing it is the better value option.
What category of fire alarm system do I need?
BS 5839-1 describes categories of system for non domestic buildings, from category M manual systems through to L1, which provides automatic detection throughout the building. The right category for your premises is normally identified by your fire risk assessment. During the site survey we explain the options in plain English and design the system to match.
