Automate Legionella monitoring to protect people and ensure compliance.

Manual temperature checks are time-consuming, inconsistent, and prone to error. By automating Legionella risk management, you can:

  • Reduce manual checks: Replace routine site visits and paper logs with continuous, automated monitoring.
  • Ensure compliance: Achieve full alignment with ACoP L8 and HSG 274 using digital records and configurable compliance summaries.
  • Improve safety: Detect and respond to risk conditions instantly with automated alerts and escalation workflows.
  • Lower operational costs: Cut time, travel, and maintenance with long-life sensors and remote visibility.
  • Scale with confidence: Manage compliance across multiple sites globally from one intuitive dashboard.
Legionella compliance status
Legionella Alert Notifications

Instant alerts.
AI-driven compliance.
Continuous monitoring.

Sensors installed at key points in your water system continuously capture live temperature data.

This information is securely transmitted via LoRaWAN® to the Live by Invisible Systems platform, where AI algorithms detect anomalies, identify risk conditions, and issue alerts before non-compliance occurs.

  • Continuous Temperature Monitoring: Tracks live temperature data across multiple water points to detect potential Legionella growth conditions.
  • AI-Driven Insights: Machine learning identifies patterns and at-risk assets, enabling proactive maintenance.
  • LoRaWAN Connectivity: Long-range, secure wireless communication independent from your IT network, ideal for complex buildings.
  • Real-Time Alerts: Automated notifications ensure swift response to potential issues.
  • Digital Audit Trail: Every reading is timestamped, encrypted, and stored for complete compliance evidence.

All data is securely stored and fully auditable, giving you a permanent digital record for inspections and reporting.

Trusted across industries where water safety matters.

Our Legionella Monitoring Solution supports compliance and occupant protection in:

  • Facilities Management: Automate Legionella checks across diverse building portfolios.
  • Healthcare: Safeguard patients and meet strict water safety regulations.
  • Education: Protect students and staff with proactive monitoring in schools and campuses.
  • Residential & Care: Maintain safety for vulnerable residents while reducing maintenance workload.

Legionella monitoring

How can I see the system in action?

You can book a live demo to explore the dashboard, review alert workflows, and see how automated Legionella monitoring transforms compliance management in practice.

What kind of support and training are provided?

Invisible Systems offers full onboarding, training, and ongoing technical support, ensuring your team can manage and interpret data with confidence from day one.

How is installation carried out?

Installation is simple and non-invasive. Sensors are mounted at key points in your water system, and the devices connect wirelessly to the LoRaWAN network. Our team or approved partners can provide full setup and configuration support.

How secure is the system?

All communications are end-to-end encrypted, and the system is designed to operate independently from your main IT infrastructure to minimise cybersecurity risks.

What happens if internet connectivity is lost?

Because the system uses LoRaWAN, data is securely stored and transmitted once connectivity resumes. No data is lost, and alerts automatically sync when communication is restored.

Can multiple sensors be connected to one device?

Yes. Each unit supports up to four temperature sensors, allowing multiple monitoring points per device to simplify installation and reduce hardware costs.

How are alerts and reports delivered?

All alerts, insights, and compliance reports are available through the central dashboard. Users can view live system status, download audit-ready reports, and configure automated notifications for risk conditions or compliance events.

How long do the sensors last before needing maintenance or replacement?

Each device is designed with low-power technology, offering up to 3.25 years of battery life, which significantly reduces maintenance frequency and total cost of ownership thanks to our flexible subscription based payments.

What connectivity does the system use?

Devices communicate via LoRaWAN®, a secure, long-range wireless protocol that operates independently of your existing IT network, ensuring reliable data transfer even in large or complex buildings.

What are the benefits of automated Legionella monitoring compared to manual monitoring?

Automated Legionella monitoring provides continuous, real-time tracking of water temperatures and automated alerts, reducing the risk of missed data and delayed responses. It eliminates manual temperature checks and paperwork, improving accuracy, efficiency, and consistency. This approach enhances safety, lowers operational costs, and provides digital records that are always audit-ready. Manual monitoring, by contrast, relies on periodic checks and manual data entry, which can be time-consuming, inconsistent, and prone to human error.

How does the system detect Legionella risk conditions?

Sensors measure water temperatures in real time. If readings fall within the temperature ranges where Legionella bacteria could grow, the system automatically sends alerts and flags affected assets for immediate action.

What types of buildings or industries can use this system?

Our Legionella monitoring solution is ideal for hospitals, schools, care homes, commercial offices, residential developments, and facilities management providers. It is suitable for any environment where water safety and compliance are a legal or operational priority.

How does this solution help with compliance?

The system supports full compliance by providing continuous temperature data, automated alerts for non-compliance conditions, and a complete digital audit trail of all readings and reports.

What is Legionella and why is it dangerous?

Legionella is a type of bacteria that can grow in water systems, particularly when water temperatures are between 20°C and 45°C. If inhaled through water droplets such as from showers or taps, it can cause Legionnaires’ disease, a serious form of pneumonia that can be fatal, especially for vulnerable individuals. Regular monitoring and control of water temperatures are essential to prevent its growth and protect building occupants.
