Overview
Construction Site Security across the UK.
Construction sites are most exposed out of hours, when plant, tools, fuel and cable are left behind fences that intruders test every night. We provide construction site security in London and across the UK: gatehouse officers, night and weekend guarding, randomised mobile patrols, CCTV towers linked to 24/7 operations, and traffic marshals for busy gates.

During working hours, officers verify contractors and deliveries at the gate, check inductions and permits, keep accurate site logs and support the site manager’s emergency procedures. Out of hours, the priority is deterrence and fast escalation: lock-up checks, perimeter patrols and a clear route to the key holder, the police or the fire service.
Cover changes with the programme. We plan it alongside the principal contractor, scale it up for high-risk phases such as fit-out and first fix, and step it down at handover. Officers are SIA-licensed and BS 7858-vetted, and are briefed on site rules, PPE and the construction phase plan.

The Risks Facing London Construction Sites
Construction sites in London are prime targets for crime and disruption. Theft alone costs UK projects an estimated £800 million to nearly £1 billion annually.
Typical threats include targeted theft of plant, copper cabling, and fuel; vandalism, fly-tipping, and graffiti; unauthorised access by trespassers or joyriders; and staff safety risks out of hours. A layered plan that combines trained personnel with physical…

Security Options For Each Build Phase
Early groundworks and enabling works often benefit from mobile patrols supported by a rapid-deploy CCTV tower. As structures rise and materials accumulate, manned guarding at the gatehouse with strict access control becomes the anchor, with targeted patrols…
High-risk locations or sites with repeated attempts can justify K9 security support for stronger deterrence. During fit-out, when tools and copper are on site, but activity varies by unit or floor, remote-monitored cameras combined with timed internal patrols…
FAQs
Construction Site Security: questions.
How much does construction site security cost?
It depends on the size of the site, the hours, and whether you need a static officer, patrols, CCTV towers or a mix. A night guard costs more than a set of randomised patrols, and towers can reduce the hours you need a person on site. We price after a site visit.
Do I need a security guard or a CCTV tower for my site?
Many London sites use both: a tower for constant coverage of the perimeter and plant, and an officer or patrols to respond and to control the gate during working hours. We advise on the mix after looking at the site, the risk and the programme.
Can your officers manage the site gate during working hours?
Yes. Gatehouse officers check contractors, inductions and permits, record vehicles and deliveries and stop unauthorised visitors, working to the site manager’s rules.
