Legionella testing should be performed regularly as part of a comprehensive water management plan. It is particularly important when there are changes to the water system, such as new installations, repairs, or after periods of inactivity

All water systems that have the potential to generate and disseminate aerosols, such as hot and cold water systems, cooling towers, and spa pools, should undergo Legionella testing. This includes domestic, commercial, and industrial buildings in Kent.

Legionella bacteria can cause Legionnaires’ disease, a severe form of pneumonia, and Pontiac fever, a milder flu-like illness. These diseases can lead to hospitalisation and, in some cases, be life-threatening, especially for individuals with weakened immune systems or underlying health conditions.

The turnaround time for Legionella test results depends on the laboratory and the testing method used. It typically ranges from a few days to a week. Some of our laboratories offer expedited services for urgent cases.

The frequency of Legionella testing in Kent should align with regulatory requirements and industry best practices. Typically, regular testing is recommended, such as monthly, quarterly or annually, depending on the type of water system, its usage, and the level of risk involved.

Legionella testing should be conducted by a certified water hygiene company – preferably a UKAS accredited body, with expertise in microbiological analysis. They have the necessary equipment, trained staff, and quality control procedures to provide accurate results. Hiring a professional also ensures reliable and unbiased testing.

If Legionella is detected during testing, immediate action should be taken to mitigate the risk. This may involve implementing control measures, such as temperature adjustments, disinfection or tank & pipe chlorination procedures, or system modifications. 

In Kent, Legionella testing is governed by national regulations, including the Health and Safety at Work Act and the Control of Substances Hazardous to Health (COSHH) regulations. Local authorities and the HSE provide guidance on Legionella control and testing requirements.

Preventing and controlling Legionella contamination requires implementing a comprehensive water management plan. This includes regular monitoring and maintenance of water systems, controlling water temperatures, ensuring proper disinfection, minimizing stagnation, and conducting Legionella testing and risk assessments.

Following established guidelines and working with professionals experienced in Legionella management is crucial.
