Commercial Fire Alarm Installation Done Properly
A fire alarm system should do more than tick a box. It needs to suit the building, support the fire strategy, and provide reliable detection and warning when it matters most.
We install fire alarm systems across Hull and East Yorkshire for offices, retail units, industrial premises, communal residential buildings, warehouses, hospitality venues and mixed-use properties — with every installation designed around how the building works in practice.
Every installation is approached with the building’s specific layout, occupancy, fire risk and day-to-day use in mind — not a generic specification applied across the board.

We provide a full service from initial design through to commissioning and handover, including extensions and upgrades to existing systems.

Frequently Asked Questions
The cost depends on the size of the building, the system type, the level of coverage required and whether this is a new installation, a like-for-like replacement, or an extension to an existing system. We provide a clear, itemised quotation following a site survey so you know exactly what you’re getting and what it will cost before any work begins.
That depends on your building layout, fire risk, occupancy and the system category required. We can advise on whether a conventional, addressable, wireless or hybrid system is the best fit as part of your site survey, taking into account your fire risk assessment and how the building is actually used day to day.
This varies depending on the size and complexity of the building, the system type and the scope of works. A small conventional system in a single-floor unit may be completed in a day, while a larger addressable installation across multiple floors could take several days. We’ll give you a realistic programme as part of your quotation.
There’s no legal requirement to use a third-party certificated installer, but your insurer may ask for one, and a fire risk assessor will expect evidence of competence. What matters is that the system is designed, installed and commissioned to BS 5839-1 by engineers who know the standard, and that you receive the documentation to prove it. We provide full design, installation and commissioning certificates on every fire alarm installation.
