    Looking for a local business security company?

    For the last 30+ years we have been designing, installing and maintaining integrated security and fire systems for businesses and establishments across the whole of London and the South East including Kent, Surrey and Sussex.

    Professional Advice, No Obligation

    Following a free survey of your business we recommend a bespoke suite of intruder alarms, CCTV, Fire Protection and Access Control to match your needs to ensure the safety and security of your staff.

    Our systems are integrated, reliable, easy to control and can be monitored for 24 hour peace of mind.

    System Maintenance & Monitoring As Standard

    Our maintenance contracts ensure your system remains intact and operational 365 days a year.  Our yearly remote and on-site inspections pick up on any potential issues before they arise and in rare cases where problems do occur, we’re the first to know and quick to fix.

    They also come with a guaranteed 4 hour response time 365 days a year, technical support over the phone, cheaper rates on parts and materials and can often lead to a reduction in your home insurance premium.

    Optional Eyes & Ears on Your Property

    Did you know we offer an intruder & fire monitoring service? Time is of the essence with intrusions, vandalism and especially fire damage to your business.

    Our monitoring services triggered by motion, fire, heat & smoke detectors send alerts to our response team (and the police/fire services) as well as your phone so that potentially catastrophic situations and the accompanying financial loss are mitigated as much as possible – even when the business is closed or the premises is empty.

    Don’t forget: All of our products are insurance approved to potentially save you money on your business insurance!
