Our Core Service

Intruder alarms,
done properly

Install, maintain, monitor and take over any alarm system. London, Surrey and West Sussex.

Specialists since 2002

London's most trusted
alarm company

Intruder alarms are not a sideline for us - they are our core service, and have been since we opened our doors in 2002. Every alarm we install is specified around the individual property, not pulled from a standard kit list.

Over two decades of doing this the right way means we have hundreds of loyal clients across London, Surrey and West Sussex. We still answer the phone ourselves. We still know your name when you call.

Wired & wireless systems
Every installation is specified around your property - its size, construction, and how you use it. We don't do one-size-fits-all.
ARC 24/7 monitoring
Connected to an approved alarm receiving centre. When your alarm activates, a professional operator responds immediately - police URN available.
System takeovers
Already have an alarm installed by someone else? We'll inherit it regardless of brand, then service, re-code and monitor it going forward.
Annual servicing
We visit every year to test every sensor, check every siren, replace any batteries and update your compliance certificate.

Monitoring & response

Always watched.
Always ready.

Your alarm is only as good as what happens next. We offer three layers of response - from professional ARC operators to your own phone - so there's always someone paying attention.

ARC Monitoring
24/7 alarm receiving centre staffed by professional operators. When your alarm activates, they respond immediately - verifying, logging and escalating to police where needed. Police URN available.
App Notifications
Get alerted directly to your phone the moment your alarm activates. View system status, arm and disarm remotely, and check zone activity - all from compatible smart alarm systems.
Annual Certification
We visit every year as standard. Every sensor tested, every siren checked, batteries replaced where needed. You receive an updated certificate keeping your system compliant and your insurer happy.
