Imperial Security provides corporate security guards for offices, embassies, law firms and mixed-use commercial buildings in Marylebone, covering reception access control, out-of-hours patrols and front of house cover for facilities managers, landlords and tenant businesses.
Marylebone's mix of Georgian townhouse offices, medical premises around Harley Street and larger commercial blocks along Baker Street and Marylebone Road means every site has different entry points, visitor volumes and out-of-hours requirements, so our guards are briefed on your building specifically rather than working from a generic script.
Marylebone is currently working through a run of overlapping office refurbishments and new-build schemes, coordinated in part by the Baker Street Quarter Partnership business improvement district, including the redevelopment at 50 Baker Street and the refurbishment of 43-45 Portman Square due to start in the third quarter of 2026. Buildings that share a street, service yard or scaffold line with an active construction site need guards who understand contractor access, hoarding lines and the extra foot traffic this brings, not just a static presence on the front desk.
Alongside the construction activity, Marylebone remains home to established occupiers who need consistent, low-key cover: consultancies and financial firms around Portman Square, medical practices and clinics on Harley Street and Wimpole Street, and independent businesses around Marylebone High Street. Our guards work with your existing office manager or facilities team rather than replacing them, adjusting shift patterns around your actual visitor flow and delivery schedule.

| What Our Marylebone Corporate Security Service Provides
Marylebone's period office conversions and larger commercial blocks each bring their own access points and visitor patterns, so our cover is built around the six duties below rather than a fixed template.
Access control and front of house monitoring
Our guards manage reception desks, verify visitor and contractor credentials, and log entries for buildings with multiple tenants or shared entrances, which is common in Marylebone's converted townhouse offices.
Surveillance and incident response
Continuous monitoring of entrances, lobbies and car parks means unusual activity is spotted and dealt with quickly, particularly useful where a site borders an active construction hoarding or service yard.
Staff and visitor safety assurance
Our guards look after your team and their visitors as much as the building itself, keeping meeting room floors, waiting areas and shared lobbies calm and well managed throughout the working day.
Emergency evacuation procedures
Trained in emergency planning, our guards can lead evacuation of period buildings with narrow stairwells or converted floorplates, coordinating with emergency services where needed.
Asset protection and loss prevention
We work proactively to secure IT equipment, confidential documents and business-critical resources, particularly during refurbishment or fit-out periods when a building is more exposed.
Concierge-level customer service
We blend security expertise with a genuinely helpful presence, assisting staff, clients and couriers with directions and day-to-day queries at the front desk.
| Who We Provide Corporate Security For In Marylebone
Marylebone's business mix means our corporate guards work across several types of occupier, often within the same street or block.
Professional services firms
Consultancies, wealth managers and legal practices around Portman Square and Marylebone Road need discreet reception cover that reflects well on their clients.
Medical and clinical premises
Practices on and around Harley Street and Wimpole Street need calm, professional front of house cover that keeps waiting areas orderly without feeling clinical.
Mixed-use office landlords
Buildings combining office floors with ground-floor retail or residential units need a single point of accountability for who comes and goes.
Facilities and building managers
Managing agents responsible for multi-tenant blocks need guards who can represent the building professionally to every tenant, not just one.
We also support retail units and short-term event spaces within the same Marylebone buildings when a corporate contract calls for it.
| The Security Problems We Solve In Marylebone
The area's ongoing office refurbishments, high footfall from Baker Street and Marylebone High Street, and its mix of tenant types all generate specific enquiries from local facilities managers.
Unauthorised access through shared entrances
Buildings with multiple tenants or a shared street entrance can attract people who are not visiting anyone in particular. A staffed reception with a clear sign-in process closes that gap without making legitimate visitors feel unwelcome.
Disruption from nearby construction and public activity
Ongoing schemes such as the 50 Baker Street redevelopment bring extra deliveries, contractor traffic and passing footfall to neighbouring buildings. Guards briefed on the current site boundaries can keep your own entrance clear and manage any spillover confusion.
Internal threats and after-hours exposure
Confidential documents, IT hardware and client information left out after hours are a genuine risk in offices without overnight cover. A guard patrol or lock-up check closes the building down properly at the end of each day.
Protest activity and public-facing pressure
Businesses on higher-profile streets can occasionally face protest or unwanted attention at the entrance. Our guards are trained to manage these situations calmly, protecting staff and visitors without escalating the encounter.
