Imperial Security provides SIA-licensed construction site security for developments across Greenwich, from Peninsula tower blocks to smaller residential and refurbishment schemes in Woolwich, Charlton and Eltham.
We work with principal contractors, developers and site managers who need reliable perimeter control, access management and out-of-hours cover for plant, materials and partially built structures. Our guards handle gatehouse duties, visitor and delivery logging, patrols and PPE checks, so your site stays secure and compliant from groundworks through to handover.
Greenwich has several large schemes running at once, which spreads security demand across the borough rather than concentrating it on one site. Knight Dragon's ongoing Peninsula masterplan continues to bring new residential towers through groundworks and superstructure phases, a twin-tower student and co-living scheme is progressing on Millennium Way, and Hill's 558-home development behind Woolwich Waves is due to start on site in spring 2026. Smaller contractors working infill plots in Charlton, Blackheath and Eltham face the same exposure to material theft and unauthorised access as the major Peninsula sites, just with less budget for on-site security management.
Multiple concurrent schemes in one borough mean multiple sites competing for the same pool of subcontractors, deliveries and, unfortunately, the attention of opportunist thieves working the area. A site that stands unguarded overnight, even for a few weeks between fit-out phases, is an easy target once word gets around locally. Our guards are briefed on the specific site layout, delivery schedule and vulnerable points before their first shift, not just given a generic patrol route.

| What Our Greenwich Construction Site Security Service Provides
Whether you are building high-rise apartments on the Peninsula or converting a smaller plot in Blackheath, our guards focus on the six duties that stop most site losses.
Perimeter security and access control
Our guards hold a visible presence at every entry and exit point, logging vehicles, deliveries and site visitors so only authorised people get onto site.
Regular patrols and incident response
Unpredictable patrols of the perimeter and internal areas catch vulnerabilities early, and our guards respond immediately if an alarm activates or intrusion is spotted.
Health and safety compliance
Guards check that everyone on site is wearing the correct PPE and help keep unauthorised people out of hazardous zones.
Theft and vandalism prevention
Constant, visible watch over timber, copper wiring, tools and plant machinery cuts the losses that come from opportunist and organised theft alike.
Delivery and contractor sign-in
With several trades and suppliers moving through a Greenwich site each day, our guards keep an accurate log of who arrived, when and why.
Out-of-hours lock-up and cover
Evenings, weekends and holiday periods are when most Greenwich sites are left exposed, so we cover the hours your own team cannot.
| Who We Provide Construction Site Security For In Greenwich
Our guards work with the full range of parties responsible for a site's security in Greenwich.
Principal contractors
Main contractors on large Peninsula and Woolwich schemes need consistent site security management across long build programmes and multiple subcontractor teams.
Residential developers
Developers building new-build flats and houses across the borough need their sites secured through every phase, from groundworks to final handover.
Refurbishment and fit-out contractors
Smaller teams converting or refurbishing existing buildings in Blackheath, Eltham and Charlton often need short-notice cover without a long-term contract.
Facilities and estate managers
Where construction work sits alongside an occupied building or estate, our guards keep the works area separate and controlled without disrupting residents or staff.
| The Security Problems We Solve In Greenwich
Several concurrent developments across the borough, from Peninsula tower blocks to smaller infill sites, have raised the volume of building materials, tools and plant sitting on Greenwich sites at any given time. That concentration of value, combined with sites that sit quiet overnight or over weekends, is what generates most of the enquiries we receive locally.
Metal and material theft
Copper wiring, lead and structural steel carry high scrap value and are easy to move quickly. We solve this with locked compounds, logged access and guards who know exactly what should and should not be leaving site.
Plant and power tool theft
Excavators, generators and power tools are targeted because they resell fast. Our patrols and access control make an unnoticed removal far harder to pull off.
Vandalism and site damage
Unsecured hoardings and partially built structures attract vandalism that can delay a build and add unplanned cost. A visible guard presence is the most effective deterrent we can offer.
Unauthorised access
Trespassers on an active site are a serious health and safety liability as well as a security risk. Our guards control every access point so only authorised, briefed individuals get near the works.
