Do you need a fire alarm system for your business?
Almost certainly, yes. Under the Regulatory Reform (Fire Safety) Order 2005, the "responsible person" for any non-domestic premises in England must carry out a fire risk assessment. They must also make sure there is a suitable way to detect a fire and warn everyone inside. In most commercial buildings, that means a fire alarm system designed to BS 5839-1.
The responsible person is usually the employer, the business owner, or the landlord or managing agent for shared areas. Your fire risk assessment sets out the level of protection your building needs. We design the system to match it.
If you don't have a current fire risk assessment, we can recommend a qualified assessor before we design anything. This avoids paying for a system that is either more than you need or not enough to satisfy your assessor.
Need a fire alarm for a house, flat or HMO rather than a business? See our page on fire alarms for homes and HMOs.
We can also connect your fire alarm to intruder alarms, door access control, lift recall, gas shut-off or music systems. The alarm then shuts systems down or opens doors automatically when it activates.
How a commercial fire alarm installation works
-
Free site survey. We walk the building, review your fire risk assessment and agree access times with you.
-
System design. We design the system to BS 5839-1: detector types and positions, call points, sounders and the panel location. You receive a written, fixed-price quote.
-
Installation. Our engineers install cabling, devices and the control panel, working evenings or weekends where needed so you keep trading.
-
Commissioning and testing. Every detector, call point and sounder is tested. We check sound levels throughout the building and confirm any links to other systems.
-
Handover. You receive design, installation, commissioning and handover certificates, a cause-and-effect matrix, a zone chart fixed at the control panel and a system logbook, in line with BS 5839-1:2025. We also show your staff how to use the panel and run the weekly test.
What changed in BS 5839-1:2025
BS 5839-1:2025 came into effect on 30 April 2025 and replaced the 2017 edition. New systems and planned upgrades should be designed to the 2025 edition. The changes that matter most for business owners:
-
Better handover paperwork. A cause-and-effect matrix is now expected at handover, showing what each device triggers, such as sounders, door releases or lift recall. The zone chart should be fixed at the main control panel.
-
"Handover" replaces "acceptance". The final sign-off stage now has a clearer name and clearer responsibilities.
-
Sleeping areas. Heat detectors should no longer be used in rooms where people sleep in L2 and L3 systems. This affects hotels, HMOs and residential care premises.
-
Alarm signalling. The standard updates its guidance on how alarms send signals to monitoring centres, ahead of the UK phone network moving fully to digital by 2027. Older monitored systems using copper phone lines may need upgrading.
-
Competence. Designers, installers and maintainers are expected to show relevant training and ongoing professional development.
If your system was installed under the 2017 edition, it doesn't automatically become non-compliant. We check it against the 2025 recommendations at your next service and tell you what, if anything, is worth changing.
Will the fire service come when your alarm goes off?
Not always, and most Manchester businesses don't know this. Since 1 August 2020, Greater Manchester Fire and Rescue Service (GMFRS) does not respond to automatic fire alarm activations between 8am and 7pm at premises without sleeping accommodation, unless someone reports a real fire. If there's a fire, always call 999.
This means your system and your procedures have to do more of the work:
-
Have a written alarm procedure. Staff need to know who checks the cause, who calls 999 and when to evacuate.
-
Train someone to reset the panel. GMFRS expects a trained, authorised person on site to do this.
-
Keep monitoring details accurate. If your alarm is monitored, the alarm receiving centre must know your premises type and whether people sleep there.
-
Warn your monitoring centre before weekly tests. This stops a test being treated as a real alarm.
-
Cut false alarms at the design stage. The right detector in the right place, such as heat detectors in kitchens, prevents most unwanted alarms.
We set up the system with these points in mind and can help you write a simple alarm procedure for your staff at handover.

What affects the cost of a commercial fire alarm?
Every building is different, so we price each system after a free site survey. You get a fixed written quote before any work starts, so there are no surprises once the job begins.
The main things that affect the price:
-
Building size and layout. More floors and rooms need more detectors, sounders and cable.
-
The category you need. Your fire risk assessment sets this. An L1 system covers the whole building, so it costs more than an L3 or L4 system.
-
System type. Conventional systems usually cost least for small premises. Addressable systems cost more but suit larger buildings. Wireless costs more per device but saves on cabling and disruption.
-
Access for cabling. Suspended ceilings are quicker to work in than solid walls, high ceilings or listed buildings.
-
Links to other systems. Door holders, access control, lift recall, gas shut-off or music systems add design and installation time.
-
Working hours. Evening, weekend or phased work keeps you trading but can take longer.
-
Your existing system. Reusing sound cabling or devices can reduce the cost of an upgrade.
Every KHL quote includes: design to BS 5839-1:2025, all devices and cabling, commissioning, handover certificates, a cause-and-effect matrix, a zone chart, a logbook and a panel demonstration for your staff. Servicing is quoted separately, so you know the ongoing cost before you commit.
Fire alarm servicing and maintenance in Manchester
BS 5839-1 recommends a fire alarm system is serviced by a competent person at intervals of no more than six months. Between visits, the responsible person should test a different call point each week and record it in the logbook.
Our maintenance contracts include:
-
Six-monthly servicing to BS 5839-1, with a certificate after each visit
-
Testing of every detector, call point and sounder over each 12-month period
-
Battery and panel checks, with replacement parts quoted before fitting
-
Fault and false alarm callouts, 24/7
-
Logbook updates, so records are ready for your fire officer or insurer
We also take over maintenance of existing systems fitted by other installers. We'll inspect the system first and tell you about any defects before you commit.
