Fuel Storage
High-value fuel stores are easy targets out of hours, leading to immediate operational disruption and costly replacement.
Cable & Copper
Copper and cabling are frequently targeted for resale, causing major delays, safety risks, and expensive repairs.
Plant & Machinery
Unsecured equipment can be quickly removed from site, resulting in downtime, project delays, and significant financial loss.
Tools & Materials
Stored tools and materials are vulnerable overnight, impacting productivity and increasing replacement costs.
Trespass & Intrusion
Unauthorised access exposes your site to theft, damage, and liability risks, often going unnoticed without active patrols.
Vandalism & Arson
Deliberate damage and fire-setting can halt operations entirely, causing severe financial and reputational impact.
What a Security Dog Handler Adds On Site
A trained dog and handler bring a visible, mobile presence to your site. Patrols can adapt as the layout, activity or risk level changes and work alongside CCTV, alarms and existing guarding where passive monitoring alone is not enough.
Changing Site Layouts
Patrols can be adapted as access points, storage areas, boundaries and work phases change.
Repeated Theft or Trespass
A stronger on-site presence can be introduced when incidents continue despite existing controls.
Unauthorised Access or Occupation
A visible team can support site management where traveller activity, trespass or unauthorised occupation is a concern.
Valuable Assets Remain on Site
Useful where plant, tools, fuel, cabling, materials or vehicles remain exposed outside working hours.
Active and Unoccupied Periods
Cover can be planned around live operations, reduced activity and the hours when fewer people are present.

Questions About Site Security Cover?
Quick answers about pricing, deployment, qualifications, night cover, site coverage and working safely around people.
How much does a security dog handler service cost?
Pricing depends on your site size, risk level, required hours and the number of teams needed. We review the requirement first, then provide a clear quotation for the cover your site needs.
How quickly can you deploy security dog handlers?
Deployment depends on your location, site requirements and team availability. For urgent requests, we will confirm what cover can be arranged and when before the team starts.
What qualifications do your security dog handlers hold?
All handlers hold a valid SIA licence and are vetted before deployment. Our dog teams are NASDU trained and assessed for controlled operational work. Supporting credentials can be supplied during procurement where required.
Are security dog handlers more effective than static security guards?
It depends on the site. A dog-handler team adds visible deterrence, active patrol coverage and earlier detection, but it is not an automatic replacement for a fixed number of guards. We recommend the right combination after reviewing your layout, duties and risk level.
Can you provide out-of-hours and night security?
Yes. Night, weekend, temporary and ongoing cover is available subject to location and team availability. These are often the periods when exposed sites face the greatest risk of theft, trespass, vandalism and unauthorised access.
What is the advantage of using a security dog handler over CCTV alone?
CCTV can monitor and record activity, but it cannot physically patrol blind areas or provide an on-site human response. A dog-handler team adds visible deterrence, active checks, earlier detection and controlled escalation. Some sites benefit from using both.
Are security dogs safe around workers and visitors?
Dogs remain under the control of their trained handler, with deployment planned around site activity, access points and public areas. The agreed response procedure also sets out how concerns are reported and escalated.
