About Us

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.
