Burglar Alarm Installation in London

Why Invest in a Professional Burglar Alarm?

According to the Office for National Statistics, London experiences a higher rate of domestic burglary than the national average. A professionally installed, NSI-approved alarm system is one of the single most effective deterrents against break-ins. Homes with monitored alarms are statistically far less likely to be targeted.

Unlike DIY systems purchased online, our alarms are designed by qualified security engineers who assess your specific property layout, identifying entry points, occupancy patterns and any particular vulnerabilities. Every Sure Alarms installation meets BS EN 50131 — the British and European standard for intruder and hold-up alarm systems.

Wired vs Wireless Burglar Alarms

Both wired and wireless burglar alarm systems have distinct advantages. Wired systems are generally more reliable for larger properties where radio frequency interference can be a concern. Wireless systems are ideal for period properties where running cables would be disruptive, and for retrofitting alarms to existing buildings.

Our engineers will recommend the most suitable type after surveying your property. We install systems from leading manufacturers including Texecom, Honeywell and Pyronix — all backed by our 10-year Sure Alarms warranty.

Monitored vs Unmonitored Alarm Systems

Unmonitored alarms sound a siren to deter intruders but rely on neighbours or passers-by to call the police. Monitored alarms connect to our 24/7 Alarm Receiving Centre (ARC), which can dispatch a keyholder or request a police response within minutes — regardless of whether you are at home.

Most London insurers now require a monitored, NSI-approved alarm as a condition of contents and buildings cover. Our monitoring contracts start from competitive monthly rates with no hidden fees.
