​Protecting People, Assets and Progress Across UK Construction Sites

Construction sites face constant operational pressures: high‑value equipment, fluctuating workforce numbers, strict safety regulations and tight project timelines. KeyNet delivers integrated security and commercial cleaning services designed specifically for UK construction and development environments — ensuring your site remains safe, compliant and productive from day one to handover.

Security Services for Construction Sites

• SIA‑Licensed Construction Security Officers - Our officers provide visible, reliable protection across live sites, compounds and multi‑phase developments. Trained for high‑risk, high‑value environments, they manage safety, access and incident response with professionalism.
• CCTV Towers, PIDS, Wireless Detection Systems - Regardless of the site size , we have an electronic solution to keep plant, people and properties safe. From compound or plant specific, to whole perimeter protection. Our weekly hire is a flexible solution for your site.
• Plant, Machinery & Material Protection - Construction sites hold valuable assets that are prime targets for theft. We provide static guarding, patrols and monitored access to safeguard tools, machinery, fuel stores, copper, cabling and other high‑value materials.
• 24/7 Mobile Patrols & Perimeter Security - Our patrol teams secure large or multi‑plot sites, checking fencing integrity, lighting, storage areas and vulnerable access points. This reduces trespass, vandalism and out‑of‑hours risks.
• CCTV Monitoring & Remote Surveillance - We integrate manned guarding with CCTV towers, remote monitoring and motion‑activated alerts to provide round‑the‑clock visibility across the site.
• Emergency Response & Incident Reporting - Keynet officers follow strict escalation procedures, delivering rapid response to alarms, breaches, accidents or safety concerns — with full digital reporting for audit trails.

Commercial Cleaning for Construction Sites

• Builders’ Cleans (Multi‑Phase) - We support construction progress with phased cleaning throughout the build, removing debris, dust and waste to maintain safe working conditions.
• Welfare Facility Cleaning - Clean welfare areas reduce sickness, improve morale and support compliance. We maintain canteens, drying rooms, toilets, washrooms and site offices daily or multiple times per day.
• Pre‑Handover Sparkle Cleans - Before client inspection or handover, we deliver detailed sparkle cleans covering fixtures, fittings, glazing, flooring, kitchens, bathrooms and high‑touch surfaces.
• Site Office & Cabin Cleaning - We keep administrative areas clean and presentable for project managers, QS teams, planners and client representatives.
• Waste Removal & Environmental Hygiene - Our teams manage waste points, segregated recycling, skip areas and general site hygiene to support environmental compliance and tidy‑site standards.
