Prove compliance.
Prevent risk.

Remote water 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, you 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.

One trusted partner. Five specialist divisions.

Through our specialist divisions, covering water and air hygiene, fire and security, electrical compliance, and lifts and escalators, we bring together essential compliance services under one supplier.

This approach helps organisations reduce complexity, improve visibility and gain greater confidence in their compliance position — whether managing a single site or a complex multi-location estate.

By providing compliance solutions in one place, we support better planning, clearer reporting and more informed investment decisions. Our approach helps organisations prioritise spend, reduce risk and demonstrate compliance with confidence.
