Legionella advice

Legionella controls during the Covid-19 pandemic

As the government is now advising home working and certain businesses have been required to close, it's important to be aware of the legionella risks in vacant or less frequently used properties. This is particularly important if there is a risk of stagnation within water systems.

As a general principle, all outlets on hot and cold water systems should be used at least once a week to maintain a degree of water flow and to minimise the chances of stagnation.

To manage the risks during non-occupancy, consideration should be given to implementing a suitable flushing regime and other necessary measures. Below are useful links with more detail:

In addition, consideration is required of other water systems no longer in use, such as leisure, sports, swimming and spa pool facilities. We suggest that for these facilities you should follow the procedures described in the Pool Water Treatment Advisory Group Code of Practice.
