Professional intruder alarms across Letchworth
Letchworth Garden City is the world's first garden city, with a unique mix of heritage commercial buildings, modern business parks, and educational establishments. We regularly work across Letchworth and nearby Baldock, providing solutions suited to both modern and period buildings.
Letchworth's Heritage Foundation manages a stock of architecturally protected buildings — including the Spirella Building and Broadway Studios — alongside modern industrial units at Letchworth Gate. The split means we move between conservation-grade installations and standard commercial fit-outs depending on the address.

Local context — intruder alarms in Letchworth
Letchworth's Heritage Foundation manages a stock of architecturally protected buildings — including the Spirella Building and Broadway Studios — alongside modern industrial units at Letchworth Gate. The split means we move between conservation-grade installations and standard commercial fit-outs depending on the address.
The Letchworth Garden City Heritage Foundation's design code restricts external alterations on protected buildings, so external CCTV and signage placement requires Foundation sign-off in addition to standard planning consent.
