Fire Alarm Installation
A professional fire alarm system is one of the most important safety measures in any commercial or industrial building. Whether you’re responsible for a busy office, warehouse, factory, retail unit, or multi-site organisation, high-quality fire detection protects your people, your premises, and your business continuity.
At City Fire Protection, we deliver a complete fire alarm installation service for businesses across the UK. From system design and supply through to commissioning and long-term servicing, we support you at every stage of your compliance journey. As experienced fire alarm installation contractors, we install systems that meet current safety expectations and are delivered in line with BS 5839 standards.
Based in London and operating nationwide with the support of the LS Fire Group, we’re trusted by organisations that need reliable protection, expert workmanship, and a fire alarm system that performs when it matters most.
Commercial and industrial fire alarm system installation
Every building presents different risks, which is why a “one size fits all” approach to fire detection rarely works. Our team carries out tailored commercial fire alarm system installation and industrial fire alarm installation based on your premises layout, risk profile, occupancy levels, and operational requirements.
Whether you need a replacement for an ageing system or you’re installing a fire alarm system as part of a new build or refurbishment, we’ll ensure your system is designed to provide clear warning, effective coverage, and full compliance.
We support a wide range of sectors, including:
- Industrial and manufacturing sites
- Warehouses and distribution facilities
- Offices and commercial premises
- Retail and mixed-use properties
- Plant rooms, workshops, and high-risk environments
Fire alarm installation that supports fire safety compliance
Fire alarm systems are not only a vital safety feature, but they’re also a legal requirement for most commercial and industrial premises. As the responsible person for a building, you must ensure appropriate fire detection and warning systems are in place, maintained correctly, and suitable for the risks within your premises.
At City Fire, our fire alarm installation service is built around compliance. We install systems in line with recognised fire safety standards, including BS 5839, ensuring your alarm system is designed, fitted, and commissioned to meet current regulatory expectations. Whether you’re fitting a system in a new industrial unit or upgrading detection within an active commercial site, our engineers ensure every stage of the installation is carried out to a high professional standard.
We don’t just install the equipment and leave you to manage the rest. At City Fire, we support you with clear documentation, commissioning certification, and practical guidance on what happens next, including servicing schedules and ongoing maintenance. This gives you peace of mind that your system is compliant, ready to perform in an emergency, and properly supported for long-term fire safety management
Our end-to-end fire alarm installation services
We provide complete fire alarm installation services from start to finish. This means you don’t need to coordinate multiple suppliers or contractors; everything is managed through one experienced team, with clear communication and reliable delivery.
Our service typically includes:
Planning and system design based on your premises and risk level, ensuring the alarm meets operational needs as well as compliance requirements. We then supply and install the most suitable system type for your building, followed by full testing, commissioning, and certification to confirm that everything is functioning correctly. We also provide guidance on ongoing maintenance and servicing to keep your system operating reliably long after installation.
This end-to-end approach makes us a trusted choice for business fire alarm installation, particularly for organisations that need long-term reliability and clear compliance support.
Types of fire alarm systems we install
Conventional fire alarm systems
Conventional systems are commonly used in smaller commercial premises where a straightforward zone-based system provides effective coverage. They offer a cost-effective solution while still delivering clear fire detection and warning signals across key areas.
Addressable fire alarm systems
Addressable systems are ideal for larger commercial and industrial buildings where more advanced detection and monitoring are required. They provide precise information on the location of an activation and support improved response times, particularly in multi-storey and complex premises.
Aspirating systems
Aspirating (air sampling) systems provide high-sensitivity smoke detection and are often used in environments where early detection is critical. These systems are particularly beneficial for higher-risk areas, specialist environments, and sites where traditional detectors may not be suitable.
Wireless fire alarm systems
Wireless systems can be an excellent choice for buildings where cabling is difficult, disruptive, or impractical. They help reduce installation time while still supporting robust detection, making them suitable for a wide range of commercial applications.
Installation of fire alarms designed around your building
The success of any alarm system comes down to more than just equipment; it’s about correct design, correct installation, and correct ongoing support. As experienced fire alarm system installers, we take time to understand your building’s risks before recommending a solution.
During a typical installation, we’ll assess the building layout, escape routes, fire hazards, usage patterns, and any high-risk operational areas. This ensures that your system is designed for effective coverage, reliable activation, and a smooth evacuation response if an alarm is triggered.
Our team will also consider how your site operates day to day, helping reduce false alarms and ensuring your system supports both safety and continuity.

Fire Alarm Installation FAQs
- What does a commercial fire alarm system installation typically include?
- A professional commercial fire alarm system installation is more than fitting devices to ceilings and walls. It should include the full process from initial design through to commissioning and handover. We start by understanding how your building is used, where the key fire risks are, and how occupants will be alerted and evacuated. We then recommend the most suitable system type and design the layout so that detectors, call points, sounders and visual indicators provide effective coverage throughout the premises. Once installed, the system is tested thoroughly, commissioned, and supplied with the relevant documentation so you have evidence of compliance. A proper handover also includes practical guidance on user testing, what common panel messages mean, and how ongoing servicing will be managed so your system stays reliable long after installation.
- Do businesses have a legal requirement to install a fire alarm system?
- In many commercial and industrial settings, yes, businesses are expected to have appropriate fire detection and warning arrangements in place as part of their wider fire safety duties. The exact requirements depend on your building type, occupancy, layout, and risk profile, which is why a fire risk assessment is so important. If a fire alarm system is required, it must be suitable for the premises and installed to a recognised standard. At City Fire, we support compliance by delivering fire alarm installation services aligned with BS 5839, ensuring your system design, installation, and commissioning follow the expectations that apply to commercial properties. Where you’re upgrading an older system or changing building use, we can also help you ensure your alarm category and device coverage remain appropriate for the risks on site.
- What’s the difference between commercial and industrial fire alarm installation?
- Both fall under professional installation of fire alarms, but the risks and environments can differ significantly. A business fire alarm installation in an office or retail unit is often focused on good audibility, clear escape route coverage, and detection suited to typical occupancies and layouts. Industrial fire alarm installation may involve additional complexities such as higher ceilings, dust or airborne particles, temperature extremes, loud ambient noise, and areas where early detection is critical due to high-risk processes or materials. Industrial sites may also require careful zoning, robust equipment choices, and specialist detection methods such as aspirating systems where standard point detectors aren’t suitable. We design and install systems around the real conditions in your building, ensuring the alarm performs reliably and reduces false alarms caused by environmental factors.
- How do I choose the right fire alarm installation company or contractor?
- Choosing between fire alarm installation companies and fire alarm installation contractors should come down to competence, standards, and the ability to deliver a compliant end-to-end service. A reputable provider should be able to explain what system type is suitable for your building, install it to recognised standards such as BS 5839, and provide full commissioning and documentation. They should also be able to support you after installation with servicing, maintenance, and fault response. At City Fire, we offer a complete installation service delivered by experienced fire alarm system installers, including design, supply, installation, commissioning, and ongoing care. This gives you continuity and peace of mind that your system won’t just be installed quickly, but installed correctly, documented properly, and supported long-term.
- What should I expect during the installation of a fire alarm, and will it disrupt my business?
- The level of disruption depends on the size and complexity of your system, whether cabling is required, and how your site operates day to day. When installing a fire alarm system, we plan work carefully around your operational needs, particularly in live commercial environments where access, noise, and working hours must be managed. We’ll agree on access requirements upfront and schedule work to reduce disruption where possible, including phased installation across zones if needed. After installation, we complete testing and commissioning to ensure that detectors, sounders, call points, and the control panel function correctly. We then provide the handover documentation and explain how the system should be managed on an ongoing basis. The result is an installation that supports compliance without unnecessarily impacting your staff, customers, or operations.

- At City Fire, we’re headquartered in London and deliver professional fire alarm installation across the capital, as well as nationwide support through the wider LS Fire Group network.
