Construction & Commercial Site Security: Nationwide Protection by Guaranteed Security

Your sites hold more than materials and machinery — they carry deadlines, delivery schedules, reputations, and livelihoods. From live building projects and industrial estates to office complexes and retail parks, you need security that prevents loss, keeps people safe, and keeps work moving.

At Guaranteed Security, we provide specialist construction and commercial site security across the UK. Our SIA-licensed officers, mobile patrol units, and technology-led solutions protect projects at every phase — groundworks to handover — with rapid deployment, 24/7 cover, and transparent digital reporting for total peace of mind.

Why Site Security Matters Now

Construction and commercial premises face a unique mix of risks:

  • Theft of plant, tools, fuel, and cabling that can halt work and inflate project costs.
  • Vandalism and unauthorised access, including trespass, squatters, and urban explorers.
  • Fire safety challenges on cladding-risk buildings or during impairment of alarms/sprinklers.
  • Health & Safety compliance at busy, evolving sites with multiple contractors and deliveries.

The impact is real: project delays, spiralling budgets, insurance issues, and reputational damage. A proactive security partner doesn’t just guard gates — we reduce risk, protect timelines, and support compliance.

What We Do

Guaranteed Security delivers a complete, scalable package for construction and commercial environments:

  • SIA-licensed, BS7858-vetted officers trained in construction H&S, conflict management, and emergency response
  • 24/7 guarding and mobile patrols to deter theft and trespass across large, changing perimeters
  • Fire Patrols / Waking Watch for cladding-risk buildings or when fire systems are impaired
  • Keyholding & alarm response to keep your teams safe and your site covered around the clock
  • Temporary & permanent CCTV with remote monitoring, audio challenge, and video evidence bundles
  • Asset & plant protection — tagging, verification, storage controls, and fuel bowser oversight
  • Real-time digital reporting — photos, patrol scans, incident logs, and KPI dashboards for managers and insurers

Services for Construction & Commercial Sites

1) Manned Guarding & Gatehouse Control

Your gatehouse sets the standard for the entire site. Our uniformed officers:

  • Control access, check CSCS cards/permits, and uphold PPE/H&S rules
  • Verify and route deliveries; manage visitor and contractor sign-in/out
  • Enforce one-way systems, speed limits, and loading bay protocols
  • Provide reception/front-of-house cover for offices and mixed-use sites
  • Maintain shift handover logs, contractor registers, and incident reports

2) Mobile Patrols & Perimeter Checks

For large or multi-plot sites, marked patrol vehicles provide a visible, unpredictable deterrent:

  • Randomised patrols at varying times and routes
  • Checks on fencing, hoardings, lighting, locks and gates
  • “Lock & unlock” routines for buildings, compounds, and plant rooms
  • Hazard spotting: fuel spills, broken panels, unsafe stacking, water leaks
  • Immediate escalation via our 24/7 control room

3) Keyholding & Alarm Response

We hold keys securely and attend alarms so your staff don’t face lone-worker risk:

  • SIA-licensed responders dispatched to verify alarms and secure premises
  • Coordination with police/fire services as required
  • Reset, re-secure, and report with time-stamped evidence
  • Optional void property checks for unoccupied buildings

4) Fire Patrols / Waking Watch (Cladding & System Impairment)

When detection systems are down, or cladding risks apply, our trained fire wardens:

  • Conduct documented patrols and verify fire doors, alarms, and AOVs
  • Identify obstructions on escape routes and keep routes sterile
  • Lead swift, safe evacuations and liaise with the Fire & Rescue Service
  • Provide compliance logs aligned to UK guidance and insurer requirements

5) CCTV Installation & Remote Monitoring

We deploy temporary CCTV towers or integrate with your existing system:

  • Rapid-deploy solar/mains towers with motion analytics & audio challenge
  • 24/7 ARC monitoring with escalation to officers or police
  • Video evidence packs for insurers and investigations
  • Integrations with access control, turnstiles, and time & attendance

6) Asset, Plant & Materials Security

Protect the items that keep your project moving:

  • Tagging & verification of high-value plant and small tools
  • Secure storage plans for fuel, copper, and cabling
  • Delivery checks against POs and chain-of-custody documentation
  • Controlled access to compounds, roof spaces, risers, and M&E areas

Sectors We Secure

  • Construction & civil engineering (new build, infrastructure, highways)
  • Demolition & fit-out (strip-out, re-clad, refurbishment)
  • Industrial & warehousing (logistics parks, distribution hubs)
  • Office & business parks, corporate campuses and mixed-use schemes
  • Retail parks & shopping centres (open, closed, or under renovation)
  • Vacant / void properties pending redevelopment or disposal

Our Process

1) Free Risk Survey
We review local crime patterns, site layout, fencing/hoardings, access points, lighting, blind spots, fire safety constraints, and insurer obligations.

2) Tailored Security Plan
A clear, costed plan covering manned guarding, patrol routes, CCTV, alarm response, lighting, and signage, by phase (enabling works, main build, fit-out, practical completion).

3) Mobilisation
Site-specific induction, RAMS compliance, escalation chain, post and patrol set-up, emergency procedures, and communications testing.

4) Live Reporting & Reviews
Digital patrol logs, NFC/RFID scan points, photo evidence, incident and near-miss reporting, and monthly KPI reviews with your PM team.

5) Continuous Improvement
We adapt as your site evolves — revising patrol routes, adding/removing towers, adjusting guard hours, and updating risk controls as buildings come out of the ground.

Standards & Compliance

  • BS7858 – Staff screening & vetting

What Our Officers Do Day-to-Day

  • Act as a visible deterrent and first point of contact for safety concerns
  • Challenge unauthorised access and manage visitor/contractor flow
  • Document incidents with photos, timestamps, and actions taken
  • Escort high-value deliveries, supervise loading/unloading
  • Monitor hot works, fuel storage, and hazardous areas
  • Conduct out-of-hours building checks and secure all access points
  • Coordinate with your site manager, principal contractor, and H&S leads

Technology That Reduces Cost & Risk

We blend people and tech for a smarter, more efficient security model:

  • Patrol verification via NFC/RFID scan points and GPS breadcrumbs
  • CCTV analytics to cut false alarms and speed intervention
  • Audio challenge to deter intruders before damage occurs
  • Dashboards & exports for insurers, QS, and project stakeholders
  • Body-worn video (where appropriate) to capture evidence and improve safety

The result? Fewer incidents, faster response, better evidence, and measurable ROI.
