A fire alarm system detects a fire early and warns everyone in the building in time to get out. We design, install, commission and maintain fire alarm systems for commercial and residential premises, from a single panel in a small unit to networked detection across a large site.

A working fire alarm isn’t optional. For most business premises it’s a legal requirement, and it’s the difference between a small incident and a serious one. Based in Leicester and available nationwide, we make sure yours is specified correctly, installed properly and signed off to the right standard.

What we install

  • Conventional and addressable fire alarm panels
  • Smoke, heat and multi-sensor detectors
  • Manual call points, sounders and beacons
  • Links to door releases, plant shutdown and other systems
  • Systems sized for anything from a small shop to a multi-building site

How we work

We start with a free site visit and a look at your legal obligations, then design a system that meets them without gold-plating it. We supply the equipment, install it to professional standards, and keep you informed at every step. Once it’s in, we commission it properly, show your people how to use it, and hand over the certification you need.

Kept working, not just fitted

A fire alarm is only worth having if it works on the day. We service and maintain systems we’ve installed and ones we haven’t, with scheduled servicing and call-outs when you need them. See Fire Alarm Servicing.

Frequently asked questions

Is a fire alarm system a legal requirement?
For most commercial premises, yes. The Regulatory Reform (Fire Safety) Order 2005 requires a suitable means of detecting a fire and warning people, and the level you need depends on the building and how it’s used. We’ll tell you what you actually need, not sell you more than that.
What's the difference between conventional and addressable systems?
A conventional panel tells you which zone a fire is in. An addressable panel tells you the exact device that’s triggered. Addressable suits larger or more complex buildings; conventional is fine for smaller ones. We’ll recommend the right one for your premises.
Do you service alarms another company installed?
Yes. We service and maintain fire alarm systems whoever fitted them, with regular servicing and call-outs when something needs attention.
