SIA-licensed construction site security
Construction site security
Sheffield-based and operating UK-wide, we protect live construction sites from theft, trespass and disruption — controlling access, walking the perimeter and securing plant, materials and copper around the clock. Every shift is GPS-verified, so the cover you commission is the cover you can prove.
What we cover
End-to-end protection for live sites
Construction sites are high-value, high-risk and constantly changing. One day's deliveries can put thousands of pounds of plant, materials and metals on the ground, and an open perimeter is an open invitation. Our construction site security wraps the whole programme — from groundworks to handover — with a trained, visible deterrent and a watertight record of who came and went.
Our SIA-licensed site security guards control the gatehouse, log contractors and deliveries, and walk the hoarding line so weaknesses are found before they are exploited. Whether you need a single static officer or full multi-shift cover across several plots, we scale the team to the site.
- Access and gatehouse control — contractor sign-in and delivery management
- Perimeter and hoarding checks to catch breaches early
- Protecting plant, materials, fuel and copper from theft
- Out-of-hours, overnight and weekend cover when sites stand empty
- Traffic marshalling on site to keep deliveries and pedestrians safe

Tech-enabled
Accountability you can hand to a site manager
On a busy site, "we patrolled overnight" is not good enough. Our officers evidence every shift as it happens, so attendance and patrols are a matter of record — not a matter of trust.
Verified shifts
Clock-in and clock-out is recorded in the TechGuard app with time and location, so you know cover was on site for every hour booked.
GPS patrol checks
Hoarding lines, compounds and plant stores are confirmed by QR scan and GPS geofencing, proving the right areas were checked at the right times.
Lone-worker welfare
Automated welfare check-ins keep solo officers safe on quiet overnight shifts, with missed checks escalated to our control room.
Audit-ready reporting
Incidents, deliveries, patrols and welfare are logged with a timestamped trail you can rely on for site managers, principal contractors and insurers.
Proven on live projects
Trusted on major UK developments
We secure sites for leading principal contractors and developers — including VolkerFitzpatrick — from infrastructure schemes to commercial new-builds. Our teams understand the rhythm of a live programme: phased access, escalating deliveries, partial occupation and the pressure of a fixed handover date. We work alongside your site management to keep the perimeter tight and the programme moving.
Accreditations
Pre-qualified and audit-ready
We arrive with the paperwork your procurement and pre-qualification teams expect. Tech Guarding is a Constructionline Gold Member and holds SSIP Acclaim accreditation, and every officer is vetted to the BS 7858:2019 standard through our Hub before deployment — SIA licence verification, right-to-work, employment history, DBS coordination and sanctions screening. It means faster onboarding to your site and confidence in exactly who is protecting it.
Construction site security FAQs
Do you provide out-of-hours construction site security?
Yes. Out-of-hours, overnight and weekend cover is when most site losses happen, so it is core to what we do. We supply static officers, lock-up and unlock cover, and mobile patrols through the night and across the weekend, all backed by our 24/7 operations team and Alarm Receiving Centre console.
Are your construction security guards SIA licensed and vetted?
Yes. Every officer holds a valid SIA licence and is screened to the BS 7858:2019 standard through our Hub platform before they set foot on site, covering identity, right to work, employment history and criminal-record checks. As a Constructionline Gold Member and SSIP Acclaim holder, our paperwork is ready for your pre-qualification process.
How fast can you deploy to a new site?
Depending on the location, we can mobilise SIA-licensed site security guards within 24 hours, and often the same day for urgent cover such as a breached perimeter or a stand-down at short notice. Our 24/7 operations team handles risk assessment, deployment and any contract changes.
How do you prove patrols were completed on site?
Officers confirm every patrol checkpoint in the TechGuard app with QR scans and GPS geofencing, so you can see the right areas — hoarding lines, compounds, plant stores — were checked at the right times. Every scan, incident and welfare check is timestamped and location-stamped, giving you a complete audit trail for site managers and insurers.
