The Bell Legacy: Protecting What Matters Since 1970

More than security, we build trust.

Founded in 1970 by Graham Bell, Bell Security Systems began with a simple philosophy: use the best equipment at an honest price and treat customers like family. This ethos has driven our success, growing from a small team into a trusted name with offices across London, Essex, and Hertfordshire. Though we’ve grown, our commitment to top-tier security, fire safety, and unparalleled customer care remains the same. We don’t just protect homes and businesses—we protect peace of mind.

"The team installed 2 wired smoke alarms and 1 heat alarm to meet the requirements of an HMO license in a rental property. The work done was of an excellent quality with the trunking and wiring barely visible and done in a very tidy manner.
