    The Key Components of Successful Legionella Testing & Monitoring Plans

    Undoubtedly, to ensure a successful Legionella control and prevention plan, it is crucial to have a well-designed monitoring plan in place. Prevention is the key focus, as it involves identifying and eliminating the factors that promote the growth and multiplication of Legionella bacteria. By implementing a comprehensive monitoring plan, you can proactively maintain the safety and cleanliness of your water system. This proactive approach is far more effective than reactive measures taken after an outbreak occurs. Therefore, it is essential to establish a strong and reliable monitoring plan to safeguard the health and integrity of your water system. Some key components of successful Legionella testing and monitoring plans include:

      Monitoring of Hot and Cold Water in Legionella Control

      To prevent the growth of Legionella bacteria, it is important to monitor the temperature of both hot and cold water in your water system. Our services include ensuring that the:

      • Hot water is stored at 60°C
      • Hot water is distributed to reach 50°C (55°C healthcare) at an outlet within 1 minute
      • Cold water is  less than 20°C                                                                                                                                                                                                                                                           By maintaining these temperature controls, you can help prevent the spread of Legionella and ensure the safety of your water system.

      Record Keeping for Legionella Testing & Monitoring 

      It is equally important to have a computerised database to show all your temperatures detailing passes and fails allowing you to take quick preventive action. According to the HSE guidelines, records must be retained for the period they remain current and for at least two years afterwards, with the exception of records kept for monitoring and inspection, which should be kept for at least five years.

Our services encompass these inspections and remedial actions to ensure the safety of your water storage systems. We will:


      • check both the inside and outside of the tank and water stored within it
      • check the tank for a secure tightly fitted tank lid with air breather
      • check for insulation on the tank to avoid heat gain & loss
      • check for ingress screen
      • check your inlet and outlet connections are on the opposite to allow good cross flow
      • check the temperature of the tank is stored below 20°C
      • check the overall condition of the tank

          The Importance of Hot Water Systems Inspections for Legionella Monitoring

          Monitoring and maintaining hot water systems is crucial to prevent the growth of Legionella bacteria. Calorifiers, in particular, can be a potential breeding ground for Legionella. To ensure their proper functioning, it is important to regularly inspect and clean them according to guidelines provided by the Health and Safety Executive (HSE). Internal inspections can be done by removing the inspection hatch or using a boroscope, and cleaning should be done by draining the vessel. These inspections and cleanings should be conducted annually. Additionally, the flow temperature of the Calorifier should be monitored monthly. Our services offer assistance in these areas to help ensure the safety and efficiency of your hot water systems: 


          • check the flow and return temperatures as outgoing should be a minimum of 60°C in order to kill legionella bacteria with a return of 50°C
          • carry out calorifier blowdowns to reduce sediment build-up which can produce a suitable environment for bacteria and reduce efficiency
          • check the pipework is insulated to prevent heat loss
          • check the calorifier internals using a borescope and clean as required, followed by chlorination or a thermal pasteurisation

            The Importance of Shower Head Cleaning for Legionella Monitoring

            Shower head cleaning is crucial for Legionella monitoring and preventing the spread of Legionnaires’ disease. When you take a shower, the water creates a fine mist or aerosol, and if the water is contaminated with Legionella bacteria, it can be inhaled into the lungs. This can lead to the proliferation of the bacteria and the development of Legionnaires’ disease.

            To ensure a safe and clean showering experience, it is important to regularly clean, descale, and flush showerheads. These measures help remove any potential bacteria and reduce the risk of Legionella contamination. By maintaining proper hygiene and cleaning practices, we can minimise the chances of contracting Legionnaires’ disease from a shower. For more information on shower head cleaning for Legionella, please refer to our informative resources.




                  Descaling and chlorination of all water outlets


                  To ensure the prevention of Legionella bacteria growth, it is important to regularly descale water equipment. Limescale build-up creates an optimal breeding ground for these bacteria. Our comprehensive range of services includes the thorough removal of limescale, as well as the cleaning and flushing of various water equipment such as:

                  • taps
                  • shower heads
                  • hoses
                  • water boilers
                  • point of use water heaters
