How Much Does a Commercial Intruder Alarm Cost?
Introduction
One of the first questions business owners ask when considering an intruder alarm is: “How much will it cost?” The answer depends on several factors – from the size of your premises to the level of monitoring required.
In this article, we’ll outline typical price ranges, what influences costs, and the key considerations when specifying an intruder alarm system for your business.
Typical Prices for Installation
While every site is unique, the following ranges are common for commercial installations in the UK:
Small office or retail unit – from £1,500–£3,000
Medium warehouse or manufacturing unit – from £3,500–£7,500
Large or multi-site premises – £10,000+
Ongoing monitoring and maintenance usually cost £300–£600 per year, depending on system size and response requirements.
What Influences the Price?
Size and layout of the premises
– More doors, windows, and internal areas mean more sensors and cabling.System grade
– Commercial insurers often require Grade 3 or Grade 4 systems, which are more robust and therefore more expensive than domestic setups.Monitoring type
– A simple bells-only alarm is cheaper, but monitored systems with police response or a 24/7 control room carry higher costs.Technology choice
– Wired systems are typically more reliable but can be more expensive to install in older buildings. Wireless systems reduce cabling but may require more maintenance.Integration with other systems
– Linking alarms to CCTV, access control, or fire detection adds value but also increases cost.Quality of components
– Higher-end sensors and control panels last longer and reduce false alarms – a worthwhile investment in the long run.
Key Considerations When Specifying Your System
Insurance requirements – Always check what your insurer mandates in terms of alarm grading and monitoring.
Future expansion – Choose a system that can grow with your site. It’s often cheaper to build in capacity upfront.
Maintenance contracts – A service agreement ensures compliance, reliability, and rapid fault response.
Accredited installers – Only SSAIB or NSI-approved companies should install commercial systems. This safeguards compliance and reliability.
Cost vs Value
While it can be tempting to shop around for the cheapest installation, the true cost of an alarm is in its performance when it matters most. An unreliable system can cost more in downtime, insurance claims, and disruption than any upfront savings.

Commercial intruder alarm pricing varies widely, but by understanding the influencing factors and planning your specification carefully, you can make a decision that balances budget, compliance, and long-term value.
