Services
Keyholding & Alarm Response
Our SIA-approved keyholding service provides 24/7 emergency response for commercial and domestic properties. Trained officers attend premises within 20 minutes of alarm activation, resolving issues while maintaining strict BS7858 compliance. This service reduces client liability and ensures continuous property protection.
Mobile Security Patrols
Uniformed patrols in marked vehicles deter crime through visible presence. Conducted at random intervals, these inspections cover vacant properties and operational sites, offering cost-effective security equivalent to on-site guards without fixed staffing costs.
Vacant Property Inspections
Regular inspections for unoccupied properties prevent vandalism and theft. Services include mail collection, leak detection, and security checks, meeting insurance requirements while maintaining property integrity during owner absences.
Temporary CCTV Systems
Rapid-deployment CCTV systems protect construction sites and vacant properties. Monitored from our 24/7 control room, these systems enable real-time threat detection and evidence collection, reducing project downtime and asset risks.
Security Guarding
Fully vetted SIA-licensed guards provide on-site security for events and permanent installations. With over 20 years' experience, our guards combine professional training with local knowledge to deliver tailored security solutions for diverse client needs.
