A sticker with a lighthouse and the word watch on it

At LCS, we know that you want to be confident that the water systems you manage and are responsible for are continually safe . In order to do that, you currently need the time each month to process monthly temperature reports and analyse data to determine if there are issues from a single temperature taken. 


The problem is you have limited time and expertise to be able to make this judgement, which makes you feel overwhelmed. Leaving your building and business reputation vulnerable to a Legionella incident. We believe that access to live data readings and our expert support services is a perfect balance to save you time, whilst achieving higher health and safety standards.


We understand, the current economic climate dictates an urgency for improvements in efficiency and automation, with a tangible ROI. Which is why over the last 7 years, we've developed a cost effective and robust Legionella control method 'Legionella Watch', which is used by countless blue chip companies to enhance their Legionella compliance strategies and ensure water safety. 



You too can have access to live data readings and our expert support network, who are monitoring your systems continually, alerting you to any change in conditions that could lead to a Legionella incident or heating system breakdown.

6 ways to revolutionise Legionella compliance

for your business

The Invisible Risk Needs Smarter Solutions

Traditional methods of Legionella risk management - manual checks, infrequent sampling, and paper-based records are no longer enough. While they were once standard practice, these outdated approaches leave buildings vulnerable to compliance gaps, unexpected outbreaks, and unnecessary operational costs.

Common Failures in Traditional Legionella Mitigation


❌ Infrequent Checks

Manual inspections (often monthly) leave long gaps between data points, allowing risks to build undetected.

❌ No Real-Time Monitoring

Without continuous oversight, water temperature, stagnation, or flow changes go unnoticed until it's too late.

❌ Human Error

Logbooks, spreadsheets, and paper trails are prone to missed entries, inconsistency, and even falsification.

❌ Reactive, Not Preventative

Issues are only addressed once they become visible problems—by then, health and legal risks may already be present.

❌ Static Risk Assessments

Outdated reports often ignore changes in building use, occupancy, or system layout—meaning your mitigation plan may no longer match reality.

❌ High Costs, Low Insight

Routine testing and flushing can be expensive, but often provide little actionable intelligence or return on investment.

The Smarter Alternative
