Fire & Security Specialists

The best fire alarm system depends on the size, layout, and risk level of your premises. For most London and Kent businesses, addressable fire alarm systems offer superior protection — they identify the exact detector triggered, reducing response time during an emergency. Smaller offices or retail spaces might benefit from conventional fire alarms, which are cost-effective and easy to maintain.

At Sigma Fire & Security, we carry out detailed fire risk assessments across London and Kent to recommend systems that comply with BS 5839 standards and local authority regulations. We design, install, and maintain systems tailored to your building type and occupancy level.

UK law (specifically the Regulatory Reform Fire Safety Order 2005) requires regular inspection and maintenance of all fire protection systems. Fire alarms should be serviced at least twice a year, and extinguishers annually by a competent technician.

Regular servicing ensures compliance, prevents faults, and guarantees that equipment performs effectively in an emergency. Sigma Fire & Security offers scheduled fire alarm maintenance across London and Kent, ensuring your systems meet insurance and safety standards all year round.

If you want 24/7 protection for your property, a monitored security system is strongly recommended. With live monitoring, any alarm activation automatically alerts our remote response centre or the police — reducing false alarms and response time.

Monitored systems are particularly important for London commercial premises, Kent homeowners, and vacant properties, where response delays can lead to theft or damage. Sigma Fire & Security provides SSAIB approved monitoring for intruder alarms, CCTV, and fire systems, giving you peace of mind around the clock.

An integrated fire and security solution connects all your safety systems — fire alarms, access control, CCTV, and intruder alarms — into one unified platform. This improves communication between devices and streamlines emergency response.

For example, when an alarm is triggered, access control doors can automatically unlock, CCTV can record the event, and fire services can be notified instantly. In busy London offices or Kent industrial sites, integration enhances both compliance and operational efficiency while reducing downtime and maintenance costs.

All commercial premises must comply with the UK Fire Safety Order 2005, which mandates a fire risk assessment, proper detection and warning systems, clear evacuation procedures, and regular staff training.

Property owners and managers — known as the Responsible Person — must ensure fire alarms, extinguishers, emergency lighting, and signage are correctly installed and maintained. Sigma Fire & Security assists London and Kent businesses with compliance audits, installations, and documentation to ensure full legal conformity and insurance approval.

CCTV systems act as both a deterrent and an evidence tool. In London and Kent, where urban density and foot traffic are high, HD CCTV cameras help prevent crime and identify incidents quickly.

Modern systems offer remote access, allowing you to monitor your site from a smartphone or PC in real time. Sigma installs IP-based CCTV systems with smart analytics, motion detection, and cloud recording — ideal for businesses, schools, and residential properties seeking reliable, modern security protection.

Yes. Modern technology allows full integration between fire alarms, intruder systems, CCTV, and smart devices through a central management platform.

For example, your fire system can send instant alerts to your mobile device, activate emergency lighting, or even trigger automatic door release for safe evacuation. At Sigma Fire & Security, we specialise in designing smart, networked fire and security systems for clients across London and Kent — combining safety, convenience, and cutting-edge control.

A proper fire risk assessment identifies potential fire hazards, evaluates who might be at risk, and determines whether existing fire precautions are adequate. It should include:

• Identification of ignition sources and materials.
• Review of escape routes and emergency lighting.
• Testing of alarms and signage.
• Recommendations for upgrades or corrective actions.
  Under UK law, all non-domestic premises must have a documented fire risk assessment. Sigma Fire & Security provides professional fire risk assessments in London and Kent, ensuring your business remains safe and compliant.

False alarms can be costly and disruptive. To prevent them:

• Keep detectors and sensors clean and well maintained.
• Ensure installation is carried out by certified engineers.
• Train staff on correct system operation.
• Use intelligent detection technology that differentiates between real threats and environmental factors like dust or steam.
  Sigma Fire & Security uses advanced systems designed to minimise false activations while maintaining high sensitivity — ideal for London offices, retail units, and Kent homes.
