> QuickAnswer: The security robot platforms worth considering for UK commercial property patrols in 2026 are Boston Dynamics Spot (with security integration, £90,000–£120,000), Cobalt Robotics (lease-based, £4,000–£7,000/month), Unitree B2 (£15,000–£22,000 with custom payload), and Ascento Guard (wheeled indoor/outdoor, available via EU distributors). None can detain or intervene physically. All must comply with ICO surveillance guidance and GDPR. The ROI case is strongest for large sites running multiple night shifts where a robot replaces two or more human guard positions.
Security robots for commercial property are no longer a future concept. They are being deployed now at logistics hubs, data centres, construction sites, and car parks across the UK. The technology is real, the legal framework exists, and the economics are starting to work for the right applications.
This guide is written for facilities managers, security directors, and commercial property teams evaluating whether a patrol robot makes sense for their site. It covers what the technology can actually do, which platforms are genuinely available in the UK, the legal constraints that matter, and an honest assessment of when the numbers work.
What Can a Security Robot Actually Do on a UK Commercial Property?
Security robots are sensing, alerting, and deterrence platforms. They are not enforcement tools.
What a patrol robot can do:
- Patrol a defined route autonomously, 24 hours a day, seven days a week
- Record continuous video and audio for CCTV-equivalent monitoring
- Detect anomalies: open doors, broken glass, unusual heat signatures (with thermal payload), unauthorised vehicles, people in restricted zones
- Alert human operators in real time via a central monitoring dashboard
- Act as a visible deterrent that affects the behaviour of would-be intruders
- Conduct perimeter checks in conditions that are hazardous or unpleasant for human guards: extreme cold, rain, chemical environments
What a security robot cannot do:
- Detain any person
- Make access control or enforcement decisions
- Intervene physically in any situation
- Replace a human response to an alert
- Exercise judgment in complex social situations
This distinction matters for procurement. A security robot is best understood as a mobile CCTV system with autonomous navigation, not as a robotic security guard with enforcement powers. Sites that need 24/7 visual coverage and anomaly detection are good candidates. Sites that need human presence for deterrence or response capacity are not.
Which Security Robot Platforms Are Available in the UK?
The UK security robot market in 2026 is early-stage but commercially real. These are the platforms with verified UK availability or active UK distribution:
| Platform | Type | UK Availability | Indicative Cost | Best Suited For |
|---|---|---|---|---|
| Boston Dynamics Spot + security payload | Quadruped | Yes, via integrators | £90,000–£120,000 (hardware + integration) | Industrial sites, construction, uneven terrain |
| Cobalt Robotics | Wheeled indoor robot | Yes, via UK distribution partners | £4,000–£7,000/month managed service | Office buildings, data centres, indoor logistics |
| Unitree B2 + custom payload | Quadruped | Yes, direct and via resellers | £15,000–£22,000 + integration | Warehouses, outdoor yards, R&D deployments |
| Ascento Guard | Wheeled bipedal outdoor | Yes, EU distribution, UK available | £35,000–£55,000 | Car parks, perimeter patrols, outdoor hard standing |
| Knightscope K5 | Wheeled indoor/outdoor | Limited UK presence | US pricing: $7–9/hour lease | Primarily US-deployed; limited UK commercial availability |
Boston Dynamics Spot is the most capable and most expensive option. Its quadruped locomotion allows it to navigate stairs, rough terrain, and construction sites that would stop a wheeled robot. Security integrations are delivered by third-party system integrators who attach camera and sensor payloads and configure monitoring dashboards. According to Boston Dynamics, Spot is deployed in over 50 countries for inspection and monitoring applications. The UK price for a security integration project typically runs £90,000–£120,000 all-in for hardware, payload, software, and commissioning.
Cobalt Robotics operates a managed-service model in which the robot is leased rather than owned, with Cobalt providing remote monitoring staff who watch the robot's feed and respond to alerts. This reduces the capital cost but increases ongoing expense and places monitoring staff outside the client's direct control.
Unitree B2 is a significantly lower-cost quadruped with comparable locomotion to Spot, available directly in the UK at £15,000–£22,000. It does not have a mature commercial security ecosystem, so deploying it as a security platform requires custom integration work. For organisations with technical teams, this is achievable. For those without in-house robotics capability, the total cost of integration brings it closer to Spot territory. See the used Unitree B2 UK buyers guide for more on the platform.
What Does UK Law Require for Security Robot Deployments?
Security robots conducting patrols on commercial property are classified as surveillance systems under UK law. The Information Commissioner's Office surveillance camera code of practice applies in full.
Key legal requirements for UK deployments:
GDPR compliance. Video and audio recorded by a patrol robot is personal data under UK GDPR. Organisations must have a lawful basis for processing this data, typically legitimate interest for security purposes, and must document their data retention policy, data subject access procedures, and any third-country data transfers (relevant if using a US cloud monitoring platform).
Surveillance camera code. The ICO recommends organisations using surveillance follow the Surveillance Camera Commissioner's code of practice. This requires signage informing people they are being recorded, proportionality assessments, and regular reviews of whether surveillance is still necessary.
SIA licensing. The Security Industry Authority licence requirement applies to persons, not machines. The robot itself does not need a licence. However, human operators who respond to robot alerts and undertake security duties on a commercial basis still require the appropriate SIA licence category.
Monitoring obligations. A robot that records but is monitored by no one is a liability. If a robot records an incident but no one watches or responds, it has not improved security outcomes and has created a data processing obligation with no corresponding benefit. All deployments should include defined monitoring and response protocols.
When Does the ROI Case Actually Work?
The comparison point is straightforward: a full-time human security guard in the UK costs approximately £28,000–£35,000 per year fully loaded (salary, NI, holiday cover, uniform, training). A guard covers one eight-hour shift. Three-shift 24/7 coverage requires three FTE, costing £84,000–£105,000 per year.
A security robot patrols 24 hours a day, seven days a week, with downtime only for charging (typically two to four hours per 24-hour period depending on platform) and maintenance. A single Cobalt Robotics lease at £5,000/month costs £60,000/year and covers continuous monitoring that would otherwise require three human positions.
The ROI calculation works when:
| Condition | Why It Helps ROI |
|---|---|
| Site requires multi-shift or overnight coverage | Robot replaces two to three FTE, not one |
| Site is large enough that patrol coverage per guard is thin | Robot covers more ground per hour than a human |
| Environment is unpleasant or hazardous for humans | Cold, wet, chemical, noisy environments increase staff turnover and cost |
| Site has defined, predictable patrol routes | Robots perform best on structured routes; unstructured environments need more integration work |
| Organisation has in-house monitoring capability | Removes dependency on managed-service providers |
The ROI calculation does not work when:
- The site primarily needs a human presence for deterrence and response rather than detection
- The environment is complex, public-facing, or socially dynamic
- The organisation lacks technical capability to integrate and maintain the system
- The site has significant infrastructure barriers: stairs, narrow doors, non-hardstanding surfaces (for wheeled platforms)
What Should You Check Before Buying or Leasing a Security Robot?
Before committing to a platform, UK security and facilities teams should answer these questions:
Site survey. Does the robot navigate your specific environment? Request a site survey from any vendor before signing. Wheeled platforms struggle with kerbs, gravel, and gradients above approximately 15 degrees. Quadrupeds handle these but are slower and more expensive.
Data sovereignty. Where is video footage stored and processed? EU/UK data centres are preferable under UK GDPR. US-based cloud processing may require a data transfer impact assessment.
Integration with existing systems. Can the robot feed into your existing security operations centre or CCTV monitoring platform, or does it require a separate dashboard? Fragmented monitoring increases operator workload and reduces response speed.
Maintenance contract. Who provides maintenance and what is the response time for a robot that is out of service? A robot that is down for two weeks waiting for a part from Asia is not providing security coverage.
Liability. If the robot injures someone (a rare but non-zero risk), who is liable? Establish this clearly with your insurer before deployment. Standard public liability policies may not cover autonomous robot operations and may require an endorsement.

Frequently Asked Questions
What can a security robot legally do on a UK commercial property?
Patrol, record, detect, and alert. It cannot detain, intervene, or make enforcement decisions. All surveillance must comply with ICO guidance and UK GDPR.
Do security robots need an SIA licence in the UK?
No. The SIA licence applies to persons, not machines. Human operators who respond to alerts and perform security duties still require appropriate licensing.
What is the cost of a security robot in the UK?
Purpose-built platforms cost £35,000–£80,000 to buy or £4,000–£8,000 per month as a managed service. Spot-based integrations typically run £90,000–£120,000 all-in. Compare against £84,000–£105,000 per year for three-shift human coverage.
Which sites are best suited to security robot patrols?
Large logistics warehouses, data centres, car parks, construction sites after hours, and industrial facilities with defined patrol routes. Avoid high-footfall public spaces and environments requiring human judgment.
Which security robot platforms are available in the UK?
Boston Dynamics Spot (via integrators), Cobalt Robotics (managed service), Unitree B2 (direct), and Ascento Guard (via EU distributors). Knightscope has limited UK commercial presence.
