What is remote monitoring?

Remote monitoring provides a smarter, safer, and more sustainable way to manage your water systems across multiple buildings. Using clip-on temperature sensors and cloud-based technology, it continuously tracks water temperatures, flow, and usage patterns in real time.

This proactive approach allows you to identify risks such as stagnation, temperature non-compliance, or system underuse before they develop into serious issues. Temperature control remains the most effective strategy for managing Legionella risk — and with continuous digital monitoring, Responsible Persons can evidence compliance, optimise maintenance, and protect people without relying solely on manual testing.

At Complii, our intelligent remote monitoring systems give you complete visibility of your water network — providing real-time assurance that every outlet, circuit, and system remains safe, compliant, and efficient.

Why choose Complii?

How we can help.

Protect your people, property, and business. Here’s why we’re the right choice for remote monitoring.

Prove compliance with confidence

Our systems automatically capture and record temperature and flow data, providing indisputable evidence of flushing regimes, compliance levels, and system performance. This digital record-keeping removes the risk of missed visits or misplaced paperwork — making audits simpler, faster, and more reliable.

Reduce your carbon footprint

By replacing manual temperature checks and unnecessary flushing, remote monitoring helps cut water waste, energy use, and travel emissions. It’s a sustainable, low-impact solution that supports your environmental and compliance goals simultaneously.

Simplify maintenance and management

Continuous data collection enables predictive maintenance rather than reactive repair. Our systems provide actionable insight to help you plan remedials, identify underused outlets, and manage water safely and efficiently.

Real-time data, visualised your way

With Complii’s connected monitoring dashboards, you can view system performance anytime, anywhere. Interactive charts and automated reports make interpreting data simple — eliminating the need for manual spreadsheets or paper-based systems.

Immediate alerts and fast response

When water temperatures fall outside safe or compliant ranges, automated alerts notify your team instantly. This allows you to take swift corrective action, minimising downtime and maintaining system integrity.

Minimise site disruption

Remote monitoring dramatically reduces the need for frequent site visits, limiting disruption to staff, residents, or patients. It also optimises resources and budgets, allowing your maintenance teams to focus on proactive system improvements.

Your questions answered.

  • It provides continuous temperature data that shows how your system performs during use and at rest. This helps identify stagnation, flow issues, or outlets that require flushing before conditions support bacterial growth.

  • We use reliable clip-on temperature sensors, typically installed on key sections of pipework. Data is transmitted securely to a cloud-based logging platform, where it can be accessed and reviewed at any time.

  • In many cases, yes. Remote systems can either replace or complement manual monitoring, depending on site requirements. For critical systems, combining both approaches often delivers the most robust compliance control.

  • Our technology provides full visibility of system performance, automated alerts for non-compliance, and downloadable compliance records. It reduces risk, saves time, and supports sustainable water management.

  • Complii’s systems are suitable for a range of environments, including hospitals, schools, offices, and industrial sites. They can be permanently installed or temporarily deployed for commissioning, risk assessment, or troubleshooting.
