Legionella Testing Services
If your business has five or more employees then the Health & Safety at Work Act 1974 states that you must commission a Legionella risk assessment on your water systems every 2 years or when there are changes to the building or the current measures are no longer adequate.
Any business big or small can be affected by a Legionella outbreak, so whether you feel it will never happen to you, the potential dangers to your staff and customers cannot be ignored.

Legionella Control in Water Systems
Légionnaires’ disease or Legionellosis is a potentially fatal form of pneumonia. People may get infected when they breathe in tiny water droplets or droplet particles left after the water has evaporated contaminated with elevated concentrations of Legionella bacteria.
Legionella bacteria grow best between temperatures of 20°C – 45°C, with optimum growth temperature being 35°C – 40°C. High temperatures usually kill the bacteria.
Legionella bacteria are found in low numbers in natural aquatic environments, for instance, lakes, rivers and ground water. As a result, it is virtually impossible to prevent Legionella bacteria entering man-made water systems.
When Should I Test for Legionella?
Legionella Testing should be carried out when the following takes place;
- Where the legionella control regime in place to treat a hot and cold water system is suspected to be inefficient
- Where ideal temperatures are not always obtained – hot water should be kept hot, and cold water cold
- Where there is doubt over concentrations of disinfectant in the system that could indicate a lack of control
- Where the situation is deemed high-risk for some other reason
