Our construction site security services in London are trusted by builders, developers and contractors.
SIA-licensed guards, CCTV towers, and mobile patrols are designed to keep your site safe, compliant and operational 24/7.
Our SIA-approved officers deliver specialist construction site security in London, trusted by building contractors, developers and property managers across the capital. With proven experience in construction security, we provide robust security solutions, including visible guard presence, remote CCTV, mobile patrols and rapid emergency response, keeping your construction site safe, secure, and operational 24/7.
London construction sites face unique challenges. The risks do not end when the workforce leaves. Every night, thieves, vandals and trespassers target valuable assets, plants, copper, tools, fuel, and machinery. Construction theft costs the UK nearly £1 billion a year, with over 6,000 break-ins annually and 1 in 5 London sites targeted by criminals. Our mission is to make sure your project does not become another statistic.
We do more than simply provide security guards, we build security plans and implement site-specific security solutions around your site’s layout, access points, and operational needs. Our skilled security guards and security experts create tailored solutions around your construction site security needs and wider construction security needs.
Every member of our security team is an SIA-licensed security officer, BS 7858-vetted, and trained in construction-phase safety, conflict management, first aid, and emergency response, combining physical security and technology for complete protection.
We provide 24/7 site security and manned guarding. Officers maintain a visible presence at gates, perimeter lines and vulnerable areas, delivering firm perimeter control and reporting suspicious activity in real time.
Static guarding is combined with scheduled and randomised patrols to cover all access points and deter unauthorised access, theft or vandalism.
We perform gatehouse duties and access control, maintaining tight site management. We screen all workers, visitors, and deliveries with ID checks and visitor logs, and we verify permits to ensure only authorised personnel enter.
Our asset and materials protection focuses on high-value tools, materials and plant equipment. We advise on secure storage, complete regular checks of designated areas, and align patrol routes to current risk.
Our mobile security patrols are ideal for larger footprints or phases that do not require full-time guarding. Our trained officers carry out perimeter checks and inspections at unpredictable times, log activity and report issues quickly.
Your project deserves more than hope.
It deserves protection.
Put trained professionals between your site and the threats waiting in the dark.
We protect residential developments and new builds, office and commercial sites, industrial and warehouse projects, rail, road and infrastructure works, power, utilities and energy sites, refurbishments and fit-outs, high-rise schemes, demolition and groundworks, vacant properties and retail shops.
Whether you manage a single build in Tower Hamlets, a city-centre project in Westminster or multiple sites across Greater London, our services can scale to match complexity and risk. We support construction companies delivering time-critical construction projects across London’s building 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. Around 1 in 5 London sites are targeted each year, roughly 40 per cent of site fires are deliberate, and 73 per cent of theft occurs outside working hours. The result is delay, higher insurance costs and avoidable safety hazards.
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 and electronic protection is essential to keep work moving.
CCTV cameras and surveillance systems add coverage day and night. We install rapid-deploy CCTV towers where cabling is not practical, deploy high-definition and thermal options with motion sensors for detection, and link them to our 24/7 operations room for monitoring and escalation, with recorded evidence to support investigations. These advanced security systems work alongside officers to strengthen deterrence.
Access control systems log every entry and exit, manage vehicle movements and help prevent unauthorised access to secure zones.
Alarm and emergency response is built in. Our officers handle alarm activations, coordinate evacuations, and liaise with police, local authorities, or fire services as needed, following agreed escalation procedures, supported by our key-holding and alarm response service.
Security dogs add visible deterrence and quick area searches where the risk profile and site rules justify K9 deployment.
We review your plan as the build progresses. As phases change, we adjust patrol routes, camera positions and access rules so protection always matches current risks.
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 to protect vulnerable zones and storage areas.
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 maintain cover without overspending. We plan these shifts in advance so that cover changes smoothly as the project moves through each phase.
SIA Approved Contractor Status covers Security Guarding and Keyholding, and every one of our officers is SIA licensed and screened to BS 7858 standards. Our ISO 9001, 14001 and 45001 management systems support quality, environmental responsibility and health and safety control.
Local knowledge and coverage span central, inner and Greater London, including Westminster, Camden, Tower Hamlets, Islington, Croydon and more. We operate 24/7 and support rapid deployment, from single night shifts for vacant plots, including empty property security and k9 dog security, through to long-term teams for complex builds.
Every one of our clients benefits from a free risk assessment and site survey, a plan shaped around project needs, clear assignment instructions, documented reporting, active supervision, quality control and responsive support, with same-day options available where resources allow.
You receive clear daily occurrence logs, patrol records and incident reports with time-stamped evidence. Patrol verification can include NFC or QR checkpoints so you can see when routes were completed.
Incidents are recorded with photos where appropriate, then escalated through an agreed call tree to your nominated contacts. Supervisors complete welfare checks and site visits, and our operations team is available 24/7 to support officers, manage handovers and update assignment instructions.
Our regular service reviews track actions, access issues and any change in risk so the plan stays aligned with the build.
We provide construction site security throughout Central, Inner and Greater London, supporting building contractors, developers, civil engineering companies and property owners.
Our coverage includes Westminster, Camden, Islington, Tower Hamlets, Croydon, Barking and Dagenham, Hackney, Lambeth, Hammersmith and Fulham, and the City of London, as well as surrounding London boroughs.
Our officers can support city-centre developments, residential building projects, commercial refurbishments, infrastructure works and sites in industrial areas. Security can be arranged for a single phase of construction or maintained throughout the project, with duties adjusted as access points, working hours and site risks change.
Every construction site has different access points, working patterns, assets and security risks. Our team can assess your requirements and recommend a practical level of protection without adding unnecessary services or costs.
During the initial discussion, we will ask about your site location, operating hours, project stage, valuable plant and materials, existing security measures and any previous incidents. This helps us determine whether you need static guarding, mobile patrols, access control, CCTV monitoring, dog handlers or a combination of services.

Because construction sites hold high-value tools, copper, plant machinery and materials that attract thieves, especially overnight. Without trained security on-site, even a small breach can lead to huge financial losses, insurance issues and project delays. A professional security presence prevents most incidents before they even begin.
