Construction Site Security Services
Construction sites remain vulnerable to theft, vandalism, and trespassing due to valuable equipment, materials, and limited off-hours supervision.
The Chartered Institute of Building reports that the UK construction industry loses over £800 million annually to theft and vandalism, with significant additional costs from project delays and insurance claims.

Advanced Construction Site Security Technology
We enhance manned guarding with construction-specific security technology designed for challenging outdoor environments and temporary installations.
Our solutions include CCTV with motion detection and remote monitoring capabilities, wireless alarm systems that require no fixed infrastructure, sophisticated motion sensors calibrated to filter environmental triggers, thermal imaging for nighttime surveillance, and comprehensive remote monitoring capabilities integrated with rapid response protocols.
These solutions provide exceptional protection for large sites, remote locations, and projects with specialized security requirements against increasingly sophisticated theft operations targeting high-value construction materials and equipment.
Tailored Construction Security Solutions
From commercial developments to residential projects, infrastructure works to renovation sites, we tailor security services to your specific project requirements and risk profile.
We adapt our strategies to address evolving security needs through different construction phases from groundbreaking to handover, ensuring continuous protection while accommodating changing site conditions, contractor requirements, and material deliveries.
Our flexible staffing models can adjust security presence based on project phases, with enhanced coverage during high-risk periods such as equipment delivery or finishing stages when valuable materials are on site.
What Construction Site Security Involves
Construction site security protects plant, tools, materials and fuel, keeps people who should not be there off site, and gives you a record of what happened and when. On most sites it is a mix of:
- Site guarding: SIA-licensed officers on site, including 24/7 cover where the risk calls for it, through our manned guarding service.
- Access control: checking contractors, visitors and deliveries at the gate against the day's list, and keeping a signed record.
- Perimeter checks: regular checks of hoarding, fencing, gates and compounds, with damage reported the same shift.
- Monitored CCTV: camera towers with 4G connectivity can be monitored remotely without mains power or broadband, and moved as the build progresses.
- Incident reporting: written reports and evidence you can share with the principal contractor, your insurer or the police.
How Cover Changes Through a Build
Risk is not the same from groundworks to handover. Early phases often need a strong perimeter and protection for plant. As the frame and envelope go up, deliveries and stored materials need watching. Near completion, fitted kitchens, boilers, copper and cabling make the site most attractive to thieves. We review cover with you at each stage so you are not paying for more than the phase needs.

Frequently Asked Questions
Common questions about our construction site security services.
What does construction site security include?
It usually combines SIA-licensed site guarding, access control at the gate, regular perimeter checks, monitored CCTV and written incident reports. The mix depends on the site, its location and the build phase. We agree it with you after a free site survey and adjust it as the project moves from groundworks to handover.
Do construction sites need 24/7 security?
Not always. Many sites are most at risk overnight and at weekends, when nobody is working. Where plant, materials or fit-out stock make the risk high, we can provide 24/7 manned guarding with SIA-licensed officers on site around the clock. Lower-risk phases may only need monitored CCTV or cover outside working hours.
Can you monitor CCTV on a site without power or broadband?
Yes. Rapid-deployment camera towers with 4G connectivity can be monitored remotely without mains power or broadband, and moved as the build progresses. Our CCTV operatives check alerts on live video and follow the response plan agreed for your site. See our CCTV monitoring services for how monitoring works.
How much does construction site security cost?
Our security guard cost guide puts construction guarding at typically £20 to £35 per hour, with overnight and weekend shifts costing more. A single guard on a 12-hour overnight shift typically costs £280 to £420 a night, and 24/7 cover £5,500 to £10,000 a month, depending on site size and risk.
Do you provide construction site security in Crawley?
Yes. We are based at the Innovation Centre in Manor Royal, Crawley, and protect sites across the town, Gatwick and the surrounding area, as well as across Sussex, Surrey and London. See construction site security in Crawley for how we work with local sites and principal contractors.
