Construction security
Construction site security that stops theft and trespass
FCS Group provides construction site security for housing developments, commercial builds and infrastructure projects across the UK. All our security guards are fully SIA licensed and trained. Our construction site security guards control the gate, check deliveries and patrol the site out of hours to protect plant, tools and materials.
Building sites change every week, so your security should too. We plan construction security around your programme, site layout and risks, and adjust cover as the build moves on. You get a named account manager, clear reporting and one number to call.

The basics
What is construction site security?
Construction site security means protecting a building site, its plant and its materials with trained, SIA-licensed officers. Sites are open, busy by day and empty at night, which makes them a target for theft of tools, fuel, cable and machinery, as well as trespass by the public. For practical tips, read our construction site security guide.
Building site security officers control the gate, check deliveries and workers, and patrol fences and compounds after hours. Many clients combine site guards with security dog teams and out-of-hours patrols to cover the whole programme.
