Imperial Security provides SIA-licensed construction site security guards for developers, main contractors and property managers building in Marble Arch, covering everything from basement and superstructure works to fit-out and final handover.
Our guards control site access, protect plant and materials, patrol the perimeter and support your team's health and safety routines, working days, nights or around the clock depending on the programme. Marble Arch sits at the western end of Oxford Street, a dense mix of retail, office and residential buildings where space is tight and footfall is constant, so a site here needs guards who can manage the public interface as carefully as the compound gate.
The approved Marks & Spencer redevelopment at the Marble Arch end of Oxford Street, alongside ongoing work around the Portman Estate, means several large sites are active or preparing to mobilise in this immediate area, sitting directly against live retail frontage and some of London's busiest pavements. That combination of high-value materials, restricted laydown space and constant passing trade is exactly the setting where a gap in access control or an unattended gate turns into a loss.
Westminster City Council's own guidance for building sites in the borough asks operators to secure scaffolding and ladders out of hours, light upper levels at night and keep a visible contact board at the hoarding, and to arrange onsite security guards during non-working hours where the site warrants it. Our teams are built to deliver exactly that standard, alongside the wider access, patrol and incident duties a live site in this part of Westminster needs.

| What Our Marble Arch Construction Site Security Service Provides
Marble Arch sites typically run tight boundaries against live retail units, basements beneath busy pavements and shared servicing routes, so our guards work to the following duties.
Site access control
Our guards run the gate, checking every visitor, delivery driver and subcontractor against your permit system before they set foot past the hoarding.
Asset and materials protection
Tools, plant, fuel and fit-out materials are watched overnight and at weekends, when a site backing onto Oxford Street is at its most exposed.
Perimeter and hoarding patrols
Regular checks of hoarding, scaffold access points and fire exits catch damage, tampering or attempted entry before it becomes a bigger problem.
Delivery and servicing management
With loading windows tightly controlled in this part of Westminster, our guards marshal vehicles in and out safely without blocking the surrounding streets.
Health and safety support
Guards flag hazards such as unsecured scaffold, blocked escape routes or unauthorised climbing, helping your site manager keep HSE compliance on track.
Emergency response
Our guards are trained to act on fire, medical incidents or intrusion and to liaise directly with the emergency services when they attend.
| Who We Provide Construction Site Security For In Marble Arch
Our guards cover the full range of building projects around Marble Arch, from major mixed-use schemes to smaller refurbishments.
Main contractors
Leading firms delivering large mixed-use and office schemes need a security partner who can staff a rolling programme without disrupting the build.
Property developers
Developers investing in high-value Marble Arch sites need cover that protects the asset from the first hoarding panel to practical completion.
Retail and office fit-out teams

Residential and mansion block refurbishments
Refurbishment projects on the area's period mansion blocks need guards comfortable working around residents while the building work continues.
| The Security Problems We Solve In Marble Arch
Sites here sit hard against some of London's busiest pavements, with retail units trading either side of the hoarding and constant pedestrian traffic past the gate. That combination drives most of the enquiries we get from this postcode.
Opportunist theft from laydown areas
Tight sites often store materials close to the hoarding line where passers-by can reach them. We position static guards and patrol routes to keep laydown areas out of easy reach.
Trespass and unauthorised scaffold access
Scaffolding on a busy frontage attracts climbers and rough sleepers overnight. Our guards check ladder access and hoarding integrity on every patrol and secure any breach immediately.
Public interface and pedestrian conflict
Narrow pavements shared with shoppers mean deliveries and plant movements can quickly cause conflict. Our guards manage the crossover point so vehicles and pedestrians pass safely.
Out-of-hours vulnerability
Evenings and weekends leave a site unattended just as footfall on Oxford Street continues. We provide overnight and weekend guarding so the site is never left unwatched.
