Imperial Security provides licensed guards for construction sites across Barnet, from major regeneration plots to single building projects. We work with developers, main contractors and site managers who need cover for access control, perimeter checks, asset protection and out-of-hours patrols. Guards are briefed on your site layout, delivery schedule and current build stage before their first shift.
Barnet is one of London's busiest boroughs for construction, driven by long-running regeneration at Brent Cross Town and Colindale alongside estate renewal at West Hendon, Dollis Valley and Grahame Park. Brent Cross Town alone is delivering 6,700 homes on a phased basis, with Brent Cross West station open since December 2023 bringing more footfall and public access close to live works. Colindale has already delivered over 3,400 homes through several housebuilders working side by side, so many separate sites share access roads, hoardings and storage compounds at the same time.
That density changes the security picture. A site inside a wider regeneration area rarely sits in isolation. Public footpaths, temporary road layouts and neighbouring plots at different stages of build all affect where a fence line needs to hold and where a guard needs to be visible. We plan cover around the stage your site is actually at, not a generic checklist.

| What Our Barnet Construction Site Security Service Provides
Across regeneration plots, estate renewal schemes and smaller residential builds, our guards focus on six core duties.
Access control
All entries and exits are checked against an authorised list, so only people who should be on site get through. This matters most on multi-phase sites in Colindale and Brent Cross Town, where several contractors can be working the same plot at once.
Perimeter patrols
Guards walk the boundary on a set schedule, checking fencing, gates and hoardings for damage or gaps. On sites bordering public paths or new road layouts, this also covers checking that pedestrian diversions are still in place and safe.
Asset protection
Plant, tools and building materials are kept under close watch, particularly overnight and at weekends when a site is otherwise empty and most exposed to opportunist theft.
Health and safety monitoring
Guards stay alert to hazards such as unsecured excavations, blocked fire routes or damaged barriers, and flag anything that needs the site manager's attention before the next shift starts.
Incident reporting
Every incident, from a forced gate to a near miss, is logged and passed to site management the same day, giving you a clear record for insurance or contract purposes.
CCTV monitoring and alarm response
Where a site already has cameras and alarms installed, our guards can monitor feeds and respond to triggers directly, useful for sites that need round the clock cover without a guard walking the perimeter constantly.
| Who We Provide Construction Site Security For In Barnet
Barnet's construction activity spans several types of buyer, each with a different security need.
Regeneration developers
Large phased schemes such as Brent Cross Town need cover that can move as the build progresses, with new compounds, hoardings and access points opening every few months.
Estate renewal contractors
Work on the borough's housing estate schemes involves building close to residents who are still living nearby, so guards need to manage access without disrupting daily life on the estate.
Small and medium building contractors
Single-plot developments and extensions in areas like High Barnet and East Barnet often need shorter-term, flexible cover rather than a long-term contract.
Site and facilities managers
Managers responsible for vacant land awaiting development need patrols to stop fly-tipping, trespass and informal access before groundworks even start.
We also cover the warehouses, logistics units and new office space that follow behind these residential schemes once they are built and occupied.
| The Security Problems We Solve In Barnet
Barnet's construction sector has changed shape over the past few years. Instead of isolated single projects, contractors are now working across dense, multi-phase regeneration areas where several sites operate side by side. That creates specific risks.
Unmanned sites overnight and at weekends
Plant and materials left on an empty site over a weekend are an easy target. We provide overnight and weekend guards who patrol on a fixed schedule and respond immediately if an alarm triggers, cutting the window when a site is vulnerable.
Shared access on multi-phase regeneration sites
Where several contractors share the same access road or compound, as at Colindale and Brent Cross Town, it becomes harder to tell who should be on site at any given time. Our guards check credentials at every entry point rather than relying on a single gate.
Public routes running close to live works
New pedestrian bridges, diverted footpaths and temporary road layouts bring the public closer to active construction than on a typical standalone site. Guards manage that boundary so pedestrians stay clear of works without needing permanent fencing everywhere.
Vacant plots awaiting development
Land cleared ahead of a future phase can sit empty for months. Left unpatrolled, it attracts fly-tipping and informal access. Scheduled patrols keep the plot secure and give you an early warning if something changes before groundworks begin.
| Why Choose Imperial Security In Barnet
Local operating knowledge
We keep track of where Barnet's major schemes stand, from the phased delivery of homes at Brent Cross Town to the housebuilders working side by side in Colindale and the estate renewal under way at West Hendon, Dollis Valley and Grahame Park. That means guards arrive already familiar with how multi-site regeneration areas operate, rather than learning the site layout from scratch.
We cover construction sites across the EN4 and EN5 postcodes, including High Barnet, New Barnet, East Barnet and Totteridge, and further into the wider North London construction market.
Guards briefed for every stage of the build
Barnet's Local Plan sets a target of over 2,300 new homes a year across the borough, which means multiple sites are live at any one time, each at a different stage from groundwork to fit-out. We brief guards on the specific stage your site has reached, rather than applying the same generic patrol to every job.

Every guard we place on a Barnet assignment meets our company standards.
- Valid SIA licensing: appropriate to the role & verified qualifications
- BS 7858 compliant vetting: five-year employment & education history
- Enhanced DBS checks: The level appropriate for your sector
