Commercial Intruder Alarm Services - Hampshire, West Sussex and the South Coast
Whether you are installing a new commercial intruder alarm system, upgrading an outdated installation, or looking for a reliable maintenance and monitoring contract, our SSAIB-approved engineers provide a complete, end-to-end service.
Every installation begins with a free site survey - we assess your premises, identify vulnerabilities, and recommend the most appropriate system for your risk profile and budget.
We design and install commercial intruder alarm systems for businesses of all sizes across Hampshire, West Sussex and the South Coast. From compact single-zone systems for small offices to multi-site enterprise installations, every system is designed around your specific requirements - the layout of your premises, your opening hours, the nature of your business and the level of protection required by your insurer.
All installations are completed to NSI Gold or Silver standards and certified on completion. We will commission the system, walk you through its operation, and ensure you know how to use it correctly before we leave.

Regular servicing is essential to ensure your intruder alarm system remains fully functional and continues to meet insurance and accreditation requirements. Under NSI standards, commercial intruder alarm systems should be serviced at least annually - and more frequently for Grade 3 systems or high-risk premises. Our maintenance contracts cover scheduled servicing visits, system testing, battery checks, sensor calibration and priority response for faults and emergency call-outs.
We service commercial intruder alarm systems installed by ourselves and by third parties. If your current provider has let you down, is no longer available, or you have inherited a system with no service history, we can carry out a full system audit and set up a maintenance contract going forward.
Already have an alarm that needs servicing? Call 01903 716445 - we cover Hampshire, West Sussex, Chichester, Southampton, Portsmouth and the South Coast.
A monitored intruder alarm provides a critical additional layer of protection - particularly for premises that are unoccupied overnight or at weekends. Your alarm is connected to a 24/7 Alarm Receiving Centre (ARC). When triggered, the ARC notifies you immediately and - if you hold a Unique Reference Number (URN) - can request a police response without delay.
A URN is issued by your local police force and is required for police response to automated alarm activations. To obtain a URN, your alarm system must be installed and maintained to the required standard by an SSAIB-approved company. As an SSAIB-approved installer, we can advise on URN eligibility and the system standard required for your premises.
Ask us about monitored alarm options and URN eligibility when you book your free site survey.
We install and maintain all categories of commercial intruder alarm system:
- Wired intruder alarm systems: the most reliable option for permanent commercial installations. Sensors, detectors and keypads are hard-wired to the control panel, eliminating battery dependency and radio interference. Recommended for new builds and major refurbishments.
- Wireless intruder alarm systems: no cables required - ideal for listed buildings, heritage properties and premises where disruption must be minimised. Modern wireless systems are highly reliable and easily expandable. Also well suited to takeover situations where rewiring is impractical.
- Hybrid systems: combine wired and wireless components on a single panel. The ideal solution for expanding an existing wired installation without full rewiring, or for premises with a mix of new and retrofit areas.
- Smart app-connected systems: control and monitor your alarm remotely via a secure mobile app. Arm and disarm remotely, receive instant notifications on alarm activation, and manage access codes for individual users - including keyholders and contractors.
Commercial intruder alarm systems are graded under PD 6662:2017 and EN 50131, which define the level of security the system must provide:
- Grade 2: the standard grade for most commercial premises. Required by most insurers for commercial buildings. Detects intruders via PIR motion sensors, door/window contacts and vibration detectors. Suitable for offices, retail premises, warehouses and the majority of commercial buildings.
- Grade 3: a higher-security grade required by some insurers for high-value or high-risk premises. Uses more sophisticated detection technology and is harder to defeat than a Grade 2 system. Required for certain police response (URN) applications.
We will advise on the appropriate grade for your premises based on your insurer's requirements, the nature of your business and the findings of your site survey.
If you have an existing intruder alarm that was installed by another company - whether the original installer is no longer trading, your maintenance contract has lapsed, or you have simply changed premises - we provide a full alarm takeover service. Our engineers will audit the existing system, assess its condition and grade, update the maintenance records and set up an ongoing service contract. In most cases, we can bring a well-maintained existing system back into compliance without the cost of a full replacement.
A commercial intruder alarm delivers maximum value when integrated with your CCTV and door access control systems. When your alarm triggers, cameras can automatically focus on the activated zone and begin recording. Access control logs can be cross-referenced with alarm activation times to build a complete picture of any incident. We design fully integrated security systems combining intruder alarms, CCTV and access control - managed through a single contract and a single point of contact.

An unmonitored alarm sounds a local siren and may send an app notification when triggered, but relies on someone nearby hearing it and responding. A monitored alarm is connected to a 24/7 Alarm Receiving Centre that alerts you and - if you hold a URN - can request a police response when your alarm activates. Monitored alarms provide significantly better protection for premises that are unoccupied outside working hours.
A Unique Reference Number (URN) is issued by your local police force and enables police to respond to automated alarm activations at your premises.
