Security Guard Service Cost: What You Really Pay in 2026 (and the Cheaper Alternative)

A manned security guard service typically costs €4,000–6,000 per month for a single guarded post, and that figure multiplies fast the moment you need genuine 24/7 coverage. Because one human cannot legally or practically stand watch around the clock, continuous cover for one location usually demands four to five rotating guards — pushing a single site well past €15,000–20,000 per month. This is exactly why forward-looking operators now benchmark security guard service cost against autonomous security robots (from €78,000) and mobile video surveillance towers (from €14,800), which deliver uninterrupted vigilance without shift rotas, sick leave or overtime.

What does a security guard service actually cost per month?

The headline hourly rate rarely tells the whole story. In the UK and across Western Europe, a static guard is charged out at roughly €22–35 per hour once employer costs, licensing, training, insurance and agency margin are included. A "single post" covered only during nights and weekends already lands around €4,000–6,000 per month. True 24/7/365 cover — the standard for construction sites, logistics hubs and critical infrastructure (KRITIS) — requires a full shift pattern of multiple guards to respect working-time limits and rest breaks.

Industry bodies report that labour accounts for over 80% of the total cost of any manned guarding contract. That means almost every euro you spend is consumed by wages and administration rather than by the security outcome itself. It also means the price only ever moves in one direction: upward, tracking minimum-wage rises and labour shortages year after year.

Why is manned guarding so expensive to run?

The 24/7 problem

A single guard covers roughly 40 hours a week. A week contains 168. To hold one post continuously you therefore need at least four to five trained officers on a rolling rota, plus cover for holiday, sickness and training days. Each additional guarded location repeats that multiplier from scratch.

The reliability problem

Human performance degrades on long, quiet night shifts — vigilance drops, patrols get skipped, incidents get missed. Studies of watch-keeping consistently show attention falling sharply after the first 30–45 minutes of a monotonous task. A machine, by contrast, does not tire, does not look away and does not negotiate its rota.

How do robots and video towers compare on cost?

Autonomous systems convert a recurring, ever-rising operating cost into a predictable, one-off capital investment. The comparison below sets classic manned guarding against BOSWAU + KNAUER hardware over a representative three-year horizon for a single site.

| Solution | Upfront price | Typical monthly equivalent* | 24/7 coverage | Scales without extra staff | |---|---|---|---|---| | Manned guard (single post) | — | €4,000–6,000 | No — needs 4–5 guards | No | | Manned guard (true 24/7) | — | €15,000–20,000+ | Yes | No | | Mobile video surveillance tower | from €14,800 | ~€470 over 36 months | Yes | Yes | | Autonomous security robot | from €78,000 | ~€2,170 over 36 months | Yes | Yes |

*Monthly equivalent shown for comparison only, spreading the one-off price across 36 months and excluding financing, connectivity and optional monitoring. Manned figures are recurring and rise with wage inflation; hardware figures do not.

Over a three-year period, a single continuously guarded post can exceed €500,000 in labour costs. One mobile surveillance tower covers the same perimeter for a fraction of that — and a fleet of towers or robots secures multiple zones simultaneously without adding a single payslip.

When should you keep human guards — and when replace them?

Manned guarding still makes sense where you need discretionary judgement, access control at a busy reception, or physical intervention. But for detection, deterrence and documentation across perimeters, yards, car parks and construction sites, autonomous systems now outperform humans on both cost and consistency.

• Mobile video surveillance towers deliver rapid-deploy, solar-capable overwatch with AI analytics, live streaming and thermal imaging — ideal for construction sites, events and temporary compounds.
• Autonomous security robots patrol on a defined schedule, detect intrusions, and escalate verified alarms to a control room — replacing the endless night patrol that no human enjoys.

Both are engineered and manufactured in Germany by BOSWAU + KNAUER, a name that has stood for durable security since 1892, and both are KRITIS-capable for critical-infrastructure environments.

Frequently Asked Questions

How much does a security guard service cost per hour?

Expect €22–35 per hour for a fully loaded static guard in the UK and Western Europe. True 24/7 cover requires four to five guards on rotation, which is why a single continuously manned post routinely exceeds €15,000 per month.

Is a security robot really cheaper than a guard?

Over a typical three-year horizon, yes. An autonomous robot from €78,000 or a tower from €14,800 is a one-off cost, whereas a single 24/7 manned post can surpass €500,000 in wages over the same period. Hardware also scales across sites without additional headcount.

Can these systems replace a guard entirely?

For detection, deterrence and evidence-grade documentation, they replace the routine patrol function outright. Many operators run a hybrid model — machines for continuous overwatch, a small human team for intervention — cutting cost while improving coverage.

Are the systems suitable for critical infrastructure?

Yes. Both the robots and the mobile towers are KRITIS-capable and operate 24/7, making them appropriate for energy, logistics, utilities and other regulated sites.

The modern alternative to classic guarding

Security guard service cost is no longer a fixed constraint you simply absorb. By shifting from rising monthly wages to predictable, one-off hardware, you gain continuous 24/7 vigilance, effortless multi-site scaling and consistent, tireless performance — backed by more than 130 years of German engineering.
