London property security decisions
Manned guarding or mobile patrol? Choose by coverage, not labels.
Manned guarding and mobile patrol solve different coverage needs. A consistent on-site presence may suit some premises, while planned checks may suit others. The appropriate model depends on the property, operating hours, access arrangements, priorities and agreed assessment.
A measured approach
Start with what the property needs at each point in time.
The right question is not “which service is better?” It is which arrangement fits the premises and the client’s purpose. A busy reception, an access-controlled office, a vacant commercial unit and a managed estate may each need a different pattern of presence, observation, access support and communication.
Static coverage and mobile patrol are not interchangeable. They can also be combined when a site needs a consistent on-site role at certain times with planned checks or additional support at others. SSS can discuss this through Manned Guarding, Mobile Patrol Security and Corporate Security Services.
Understand the distinction
Compare the operating model, not the job title.
Use these differences to shape the first discussion. The exact duties and coverage will be confirmed only when the property and its operating arrangements are understood.
Manned guarding
May suit a requirement for a consistent, agreed on-site role during defined hours or across a defined operating period.
Mobile patrol
May suit premises that need planned, visible checks without a permanent on-site presence at every point in the day.
Combined approach
May suit a property that needs different coverage patterns across opening, peak, closed or handover periods.
Site-specific scope
The final model should reflect access, visitor flows, occupancy, site layout, responsibilities and agreed priorities.
Decision matrix
Ask what needs to be present, planned and visible.
The matrix is a conversation tool, not a promise of a particular outcome. It helps property teams explain why the coverage pattern matters.
| Decision area | Manned guarding may suit | Mobile patrol may suit |
|---|---|---|
| On-site role | A continuous or defined-hour on-site role is needed for an agreed set of responsibilities. | The property needs scheduled or agreed checks rather than continuous static cover. |
| Access and visitors | A consistent front-of-house or access-support presence is part of the required operating model. | Access arrangements are largely managed by the client, with security checks planned around the site brief. |
| Property rhythm | The site has predictable daily activity, handovers or occupancy periods that need a sustained presence. | The property’s priority is a flexible pattern around closed, lower-occupancy or defined checking periods. |
| Information and handover | A regular on-site handover and visible service interface is important to the client. | Information can be agreed through the client’s contacts, site instructions and planned reporting arrangements. |
| Mobilisation inputs | The role needs detailed site instructions, contacts and day-to-day responsibilities. | The patrol scope needs clear access, visit, contact and exception-handling information. |
Four questions before you ask for a quotation.
Giving a provider these inputs will make the discussion more useful than starting with a generic service label.
When does the site need support?
Map normal, peak, closed and exceptional operating periods without assuming one coverage model fits all.
What must happen on site?
Identify agreed duties such as access support, visitor interface, checks, handovers or incident escalation.
Who owns each decision?
Clarify site contacts, property/facilities responsibilities and how the security team should raise exceptions.
What evidence is useful?
Agree the operational records, handover notes and review points that help the client oversee the service.
A proportionate approach
Security should fit the property’s actual operating rhythm.
SSS can help a client discuss a suitable model around the premises, agreed responsibilities and how the service will be overseen. It is not responsible to promise a universal coverage pattern before those facts are known.
Questions answered
Useful answers before you make contact.
These answers are general operational guidance. The final scope should be agreed through a site, event or client-specific discussion.
Is manned guarding always more suitable than mobile patrol?
No. The appropriate model depends on the premises, coverage objective, operating hours, access arrangements and written brief. Some properties may use a combination of approaches.
Can mobile patrol replace every on-site security role?
No. Where a site requires a continuous agreed on-site role, regular front-of-house support or specific responsibilities during operating hours, a planned patrol model may not meet the same need.
How do I decide which model to request?
Start with the site’s daily pattern, the activities that need support, ownership of decisions and the reporting or handover information the client needs.
Guide notes
Clear guidance. Sound boundaries.
Reviewed 23 September 2026. Protective-security decisions should be proportionate to the property and its agreed operational requirements. This page does not assess a specific site or set a universal standard for staffing, patrols or response.

Start with a practical conversation
Clarify the coverage, then choose the model.
Talk to SSS about the property’s operating pattern and prepare a security scope that can be discussed sensibly.
