About CJS Fire & Security

CJS Fire & Security are a Bristol-based fire alarm and security engineering company serving businesses across Bristol, Bath, Weston-super-Mare and the wider South West.

Founded by a qualified electrician with 14 years of hands-on industry experience in the fire and security trade, CJS was built on a simple principle: that clients deserve honest advice from engineers who actually understand the systems they're installing.

We design, install and maintain fire alarm systems, CCTV, access control, intruder alarms and electric gates for commercial premises across Bristol and the South West. Every job is carried out by our own directly employed engineers — no subcontractors, no national company managing accounts from a distance.

Our engineers hold FIA training and multiple manufacturer certifications. We've been trading for four years, building long-term relationships with clients across manufacturing, schools, HMOs, offices, care homes and commercial premises throughout the Bristol region.
