About Us.

Security Alarm Services was established over 35 years ago in November 1984, when Robin Swan-Liddell left West Mercia Constabulary making the move into the security industry.

From its offices in Ross-on-Wye, Security Alarm Services quickly established an unrivalled reputation as the area’s leading supplier of alarm, CCTV and monitoring equipment through its professional yet friendly service.

Its wide spectrum of both business and domestic customers can be found throughout Herefordshire, Gloucestershire, Forest of Dean, Monmouthshire, Worcestershire and the surrounding areas. Some key clients who trust Security Alarm Services with their security alarm requirements include, PGL, MF Freeman, Nationwide Crash Repair, Spar and Co-op.
