Does a commercial property need a fire alarm?

Under current UK law, all commercial properties must have what’s defined as an “appropriate fire detection system.” In practice, this means that every business property should have a fire alarm in place because it is the most effective detection system available.

Legally, small, open-plan and single-storey properties where fires can be easily seen from any point are exempt from the rules. However, fire can spread surprisingly quickly, meaning a fire detection and alert system is critical to protecting your employees and customers even in these environments.

Types of commercial fire alarm systems

Commercial fire alarm systems are a must-have for any commercial premises in the UK; but which alarm system is right for you?

At Wells Electrical, we understand how overwhelming the sheer amount of choice can be. Generally, you can split commercial fire alarm systems into four distinct categories, which are:


Conventional – These are simple, stand-alone systems with hard-wired devices that detect fires and alert all building occupants. These are inflexible but are also the simplest, most cost-effective option to install.

Addressable – Addressable fire alarm systems are networked systems using sensors and detectors connected to a central control panel. Each device within the system has its own unique address, which is why these systems can tell you exactly where a fire is located. Compared to a conventional system, these offer far greater precision.

Analogue Addressable – These fire alarm systems consist of field devices connected to a control panel via cabling. Although more expensive, these alarm systems offer more accurate fire detection and are more adept at telling the difference between real fires and false alarms.

Wireless – These fire alarm systems are similar to analogue addressable systems but without the need for cabling. Instead, it relies on radio frequencies to connect the detectors to the rest of the system. Offering frictionless, fast installation, these are the most flexible commercial alarm systems available today.

Fire alarm regulations for commercial buildings in the UK

All fire alarm regulations for commercial facilities are part of The Regulatory Reform (Fire Safety) Order 2005, abbreviated as the RRO.

Additionally, UK government recommendations state that fire alarm and detection systems should be installed and regularly maintained to the standards of BS 5839.

How much does it cost for commercial fire alarm system design and installation?

Business owners should never view commercial fire alarm system design and installation as a box-ticking exercise. Instead, businesses must be prepared to provide the maximum amount of safety possible.

However, the key to any sound fire alarm system is to design and install it based on the building. No two commercial premises are the same.

With that in mind, Wells Electrical provides tailored quotes based on your business and current Fire Review Assessment.
