Mobile security patrols in London send an SIA-licensed officer to your premises to check it is secure, lock or unlock, and report what they find, without paying for a guard all night. Across Central London, a patrol officer is usually on site within the hour for an alarm or an unplanned visit. There is no contract, and every update arrives on WhatsApp.
On a typical visit, the officer will:
If the officer finds a break-in in progress, they call the police first. Patrol officers have the same legal powers as any member of the public.
| Patrol type | What happens | Suits |
|---|---|---|
| Scheduled patrol | Visits at agreed times, such as 10pm and 3am | Empty shops, offices closed at weekends |
| Randomised patrol | Visits at varied times within a window | Sites where intruders watch for a routine |
| Lock and unlock | An officer opens up or secures the building | Premises with no keyholder nearby |
| Alarm response | An officer attends when the alarm activates | Monitored alarms, absent owners |
| Follow-up visit | A check after a break-in or a repair | Sites waiting for a glazier or locksmith |
Patrols give you a regular presence for far fewer hours than a static guard, but nobody is on site between visits. If a site holds high-value stock or has people coming and going, manned guarding is stronger. Patrols work well for:
Shutters down and a doorway that attracts fly-tipping.
A Saturday night check that doors are locked and nothing is running.
A managing agent with blocks in Camden and Islington books one visit to each rather than two guards. See apartment block security.
See vacant property security for inspections and squatter deterrence.
Most patrols check the outside only. For internal checks, lock-ups or alarm resets, the officer needs keys or codes. Holding a client’s keys is licensable key holding work under SIA rules.
Use WhatsApp, Facebook Messenger or the Sparta Guard app.
Give each address, the best access point and any hazards.
Tell us how many visits, at what times or within what window, and on which days.
Local SIA-licensed, DBS-checked officers attend and you get updates on WhatsApp.
For a one-off visit rather than a recurring patrol, see property security checks.
A ground-floor unit has been empty for two months and someone has tried the shutter lock. Two randomised visits a night start that evening.
The owner is abroad for a fortnight. An officer unlocks for the cleaner on Mondays and locks up afterwards.
The alarm keeps activating overnight. An officer attends and traces it to a faulty sensor for the alarm engineer.
You pay per visit. The price depends on the number of visits, the time of day, whether internal checks are included and how far apart your sites are. Regular customers can ask about membership plans.
A mobile security patrol is a series of visits by a licensed officer who checks that premises are secure, rather than staying on site all shift. The officer inspects doors, windows and perimeters and reports back. Patrols suit empty buildings, sites closed overnight and owners with several small properties.
They can be, but they do not have to be. Scheduled visits suit lock-ups and routine checks. Randomised visits within an agreed window are harder for anyone watching the site to predict, which makes them a better deterrent for empty or targeted premises.
Yes. Alarm response is one of the services you can book. An SIA-licensed officer attends, checks the premises and tells you what triggered the alarm. Across Central London, the officer is usually on site within the hour, and you get updates on WhatsApp.
A patrol is priced per visit, while a static guard is priced by the hour. For a quiet site that needs checking two or three times a night, patrols usually cost less than a full shift. Message us your sites and pattern and we will confirm the price before booking.
Only if you want internal checks, lock-ups or alarm resets. External patrols of doors, shutters, fencing and yards need no keys at all. Where keys or codes are needed, we agree in advance how they are handed over, stored and returned.
Message us now and local SIA-licensed responders are alerted straight away.
Simple. Discreet. Always local.
