What is mobile patrol security?
Mobile patrols provide visible security presence via scheduled visits by officers who check premises, report issues, and deter crime.
Mobile patrol security is a cost-effective alternative to static manned guarding. Rather than stationing an officer on your premises full-time, SIA-licensed officers visit your site at scheduled intervals throughout the day or night, arriving in marked Vigil vehicles. Each visit involves comprehensive external and internal checks covering doors, windows, gates, perimeters, car parks, and alarm systems. Officers use our digital patrol system to scan NFC checkpoints at agreed locations, generating GPS-timestamped proof of attendance.
A typical overnight patrol service involves 2-4 visits between 20:00 and 08:00. Officers arrive at randomised times within agreed windows (e.g., between 22:00-23:00, 00:00-01:00, 03:00-04:00) to prevent predictability. Each visit lasts 15-30 minutes depending on site size. Officers inspect all external access points, walk the perimeter, check for signs of forced entry or trespass, test door locks, inspect windows, confirm alarm systems are set, and report any maintenance issues, lighting failures, or suspicious activity.
Mobile patrols are widely used across offices, warehouses, industrial estates, retail premises during closure periods, construction sites outside working hours, and vacant properties awaiting sale or redevelopment. They provide visible deterrence — marked vehicles and uniformed officers reduce opportunistic crime — at a fraction of the cost of 24/7 manned guarding.
How mobile patrols work
Scheduled visits, site-specific routes, digital checkpoints, and automated reporting via client portal.
Before deployment, we conduct a site survey to identify all access points, perimeter boundaries, high-risk areas, and locations requiring inspection. We agree a patrol route with you and install NFC checkpoint tags at key locations (e.g., main entrance, rear gate, loading bay, perimeter corners). Officers scan these checkpoints during each visit using our patrol management app, which records the exact time and GPS location of each scan.
Visit frequency and timings are tailored to your risk profile. A standard overnight service might include 2 visits (e.g., 22:30 and 03:30) or 3 visits (21:00, 00:00, 04:00). Higher-risk sites such as construction sites with valuable plant or warehouses with high-value stock may require 4+ visits per shift. Daytime patrols are also available for retail premises, car parks, or office complexes requiring regular checks during trading hours.
Visit times are randomised within agreed windows to prevent predictability. For example, if your contract specifies a visit between 22:00-23:00, the officer will arrive at a different time within that hour each night. This randomisation prevents criminals from observing and predicting patrol patterns.
At the end of each visit, the patrol app automatically generates a report listing all checkpoints scanned, the time spent on site, observations made, and photographs of any defects or concerns. The report is uploaded to our client portal within 30 minutes of the visit completing. You receive an email notification for each patrol and can log into the portal at any time to review historical reports or download them for insurance or audit purposes.
Mobile patrols vs manned guarding — which is right for your site?
Mobile patrols suit lower-risk sites requiring periodic checks; manned guarding suits high-footfall sites needing continuous presence.
Mobile patrols are ideal if your premises are unoccupied for extended periods (e.g., offices closed overnight, warehouses operating single-shift, retail stores after trading hours), your site has robust physical security (e.g., perimeter fencing, alarm systems, CCTV) but benefits from periodic verification, you want visible deterrence without the cost of full-time guarding, or you need security coverage for vacant properties, construction sites outside working hours, or industrial estates with multiple tenants.
Manned guarding is better if your premises operate 24/7 or have high footfall requiring access control, you hold high-value stock or equipment that makes you a target for organised crime, you require continuous CCTV monitoring or visitor management, regulatory or insurance requirements mandate on-site security presence, or your site has experienced repeated security incidents or is located in a high-crime area.
Many clients combine both services. For example, a construction site might have manned guarding during the day for access control and welfare supervision, plus mobile patrols overnight to check perimeters and deter theft. A retail chain might use manned guarding for flagship stores in central London and mobile patrols for suburban branches. We can structure a hybrid solution tailored to your operational hours and risk profile.
What officers check during each patrol visit
External doors, windows, gates, perimeters, car parks, alarms, lighting, and CCTV — reported via GPS-tracked checkpoints.
External access points: Officers test all doors and gates to confirm they are locked and secure. If a door is found insecure, the officer investigates whether it was left open accidentally or shows signs of forced entry, secures it if safe to do so, and escalates the issue immediately.
Windows and glazing: Officers inspect ground-floor windows and any accessible upper-floor windows for damage, forced entry attempts, or breakage. Photographs are taken of any defects.
Perimeter and boundaries: Officers walk the site perimeter checking fencing, gates, and boundary walls for breaches, gaps, or signs of trespass. This is particularly important for construction sites and industrial premises.
Car parks and loading bays: Officers check for unauthorised vehicles, suspicious persons, or vehicles with windows smashed. Many break-ins occur via car parks and rear loading areas that are less visible from the street.
Alarm systems: Officers confirm that alarm panels show the system is set correctly. If an alarm is not set when it should be, or shows a fault condition, this is reported immediately.
External lighting and CCTV: Officers check that security lighting is operational and CCTV cameras are positioned correctly. Criminals often disable or reposition cameras before attempting entry.
Internal checks (if access is provided): If you provide a key or access code, officers can conduct internal patrols checking reception areas, corridors, stairwells, and any specified rooms or storage areas.
Mobile patrols for construction sites
Overnight patrols to deter theft of plant, tools, and materials from London construction sites.
Construction site theft costs the UK industry over £800 million annually according to HSE data. Mobile patrols provide a visible deterrent at a lower cost than 24/7 static guards. Officers patrol the site perimeter, check hoarding and gates for security, inspect welfare units and site offices for signs of forced entry, confirm that plant machinery such as excavators and telehandlers are immobilised and secured, and report any suspicious vehicles or persons loitering near the site.
For high-value sites or those in high-crime areas, we often recommend 3-4 patrols per night combined with visible signage warning that the site is under patrol. Many contractors also use our construction site security manned guarding service during high-risk phases such as fit-out when valuable materials are on site.
All officers assigned to construction site patrols are briefed on CDM 2015 site safety requirements and wear appropriate PPE including hard hats, hi-vis vests, and steel-toe boots when conducting patrols.
Alarm response and key holding
Mobile patrol officers can respond to alarm activations if combined with our key holding service.
If your premises are protected by an intruder alarm monitored by an alarm receiving centre (ARC), you are required to nominate keyholders who can attend within a specified time if the alarm activates. Many businesses struggle to maintain a list of staff willing to attend callouts at 3am, particularly if false alarms are frequent.
Vigil offers a dedicated key holding and alarm response service. We hold copies of your keys in a secure, audited key safe. If your alarm activates, the ARC contacts our 24/7 control room. We dispatch the nearest available officer to your premises — typically within 20-30 minutes for Greater London sites. The officer attends, unlocks the premises, conducts an internal search, identifies the cause of activation (e.g., faulty sensor, open window, genuine intrusion), secures the premises, resets the alarm if appropriate, liaises with police if a crime has occurred, and produces a detailed incident report.
Many clients combine mobile patrols with key holding and alarm response to create a comprehensive overnight security solution at lower cost than manned guarding. See our Key Holding & Alarm Response page for full service details.
Mobile patrol coverage across Greater London
Greater London coverage with response times of 20-30 minutes for most locations.
Vigil operates a fleet of marked patrol vehicles based strategically across Greater London to ensure rapid response times. We cover all Greater London boroughs including central London (Westminster, City of London, Camden, Islington), east London (Tower Hamlets, Hackney, Newham, Barking & Dagenham), south London (Southwark, Lambeth, Croydon, Bromley), west London (Ealing, Hounslow, Hillingdon), and north London (Barnet, Enfield, Haringey).
For routine patrols, we guarantee visits within your contracted time windows. For alarm response callouts, we aim for 20-30 minute attendance for most Greater London locations, with faster response for central and inner London sites. Response times are tracked and reported in your monthly KPI summary.
If you operate multiple sites across London, we can provide mobile patrols under a single contract with one account manager, consolidated invoicing, and unified reporting. This simplifies procurement and ensures consistent service standards across your portfolio.
Patrol reporting and client portal
Automated reports with GPS timestamps, checkpoint scans, photographs, and observations uploaded within 30 minutes of each visit.
Every patrol visit generates a detailed report accessible via our secure client portal. Reports include the date and time of the visit, the name and SIA licence number of the attending officer, GPS-stamped location data confirming the officer attended your site, a list of all checkpoints scanned with individual timestamps, observations made during the patrol, photographs of any defects or security concerns, confirmation that the site was left secure, and the total time spent on site.
You receive an email notification each time a new patrol report is uploaded. You can log into the portal at any time to review reports, download them as PDFs for insurance or audit purposes, or set up custom alerts (e.g., notify me immediately if a patrol identifies an insecure door or suspicious activity).
If an urgent issue is identified during a patrol — such as a door left insecure, signs of attempted break-in, or suspicious persons on site — the officer will call you directly before leaving site in addition to logging the issue in the patrol report. This ensures you are aware of critical issues immediately rather than discovering them the following morning.
Pricing and contract terms
Fixed monthly fee based on visit frequency and site location — no hidden charges for reports, checkpoints, or callouts.
Mobile patrol pricing is typically structured as a fixed monthly fee based on the number of visits per night or week and your site location. For example, a standard overnight service with 2 visits per night across 7 nights per week might cost £200-£350 per month depending on your London borough and site size. Adding additional visits or weekend-only coverage adjusts the price accordingly.
There are no hidden fees. The quoted price includes unlimited patrol reports, GPS tracking, client portal access, and NFC checkpoint installation. If you add alarm response or key holding, there is a small additional monthly retainer plus a per-callout fee (typically £45-£65 per attendance).
Contracts are typically rolling monthly agreements with 30 days' notice for termination, or fixed-term contracts for 6 or 12 months. We do not impose long tie-ins. If your requirements change — for example, increasing visit frequency during a closure period or pausing the service during a refurbishment — we can adjust the contract with 7 days' notice.
