Stop Treating Legionella Compliance Like a Tick-Box Exercise

Traditional monthly checks give you a snapshot in time,

not an understanding of how risk develops between inspections.


Legionella Watch provides continuous, data-driven visibility, so you can manage Legionella risk as an ongoing process, not just demonstrate compliance at inspection points.

Certified member of the Legionella Control Association (LCA) and trusted nationwide by high-stakes sectors like Healthcare and Housing.

The Truth: Your Legionella Compliance

Might Only Look Safe on Paper

For years, Legionella monitoring has followed the same pattern:

the same outlets, the same time each month, the same “all clear” report.


It’s convenient.     It’s predictable.      And it often provides a false sense of certainty.

Built Around Calendars, Not System Behaviour
Monthly Snapshots, Not Ongoing Insight
Tick-Box Evidence, Not Continuous Control

Checks happen when access is convenient, not necessarily when water systems are most vulnerable.

A temperature reading taken once a month shows what happened at that moment, not what occurred during the other 29 days.

Duty holders receive reports that appear compliant, while conditions that allow Legionella to develop can emerge quietly between visits.

No news is not the same as no risk.


It usually just means risk hasn’t become visible yet.

If Buildings Have Moved On,

Why Has Legionella Monitoring Stood Still?

A person examines a complex plumbing system, writing on a clipboard. The system has red and blue pipes in a utility room.

Today’s buildings are complex, dynamic environments: Occupancy patterns change, Systems are extended or reconfigured, Outlets go unused.


Expectations around safety, governance, and ESG continue to rise. Yet many organisations still rely on a monitoring model designed for static systems and predictable use.


Modern Legionella management needs to recognise a simple reality:

Water systems change continuously, risk develops over time.

Effective monitoring should therefore be:

  • Continuous or high-frequency – providing visibility beyond monthly snapshots
  • Risk-led – guided by system behaviour, not diary availability
  • Transparent – giving duty holders ongoing insight, not delayed reassurance
  • Flexible – allowing protection levels to evolve as buildings and usage change

Meet Legionella Watch:

Continuous Visibility for an Ever Evolving System

Legionella Watch replaces routine box-ticking with ongoing, data-driven visibility, so you can see how your water systems behave over time, not just at inspection points. It doesn’t claim to “finish” compliance. It helps you stay oriented as conditions change.

Managing Legionella Risk as an Ongoing Process

Every site is different. What matters is not reaching a finish line, but maintaining visibility as systems change.

1. Discovery & Context

We review your buildings, systems, and current control approach to understand where visibility exists, and where it doesn’t.

2. System Setup & Alignment

Legionella Watch is configured to reflect your systems, risk profile, and reporting needs, designed to evolve, not remain static

3. Monitor, Respond, Evidence

You gain continuous insight, alerts, and defensible evidence, supporting informed decisions as conditions change over time.
