Recent cases of Legionnaires’ disease in the Midlands are a powerful reminder that employers, the self-employed and people in control of premises (such as landlords) have a duty to identify and control risks associated with legionella.

If your building has been closed or had reduced occupancy during the coronavirus (COVID-19) pandemic, water system stagnation can occur due to lack of use, increasing the risks of Legionnaires’ disease.
You should review your risk assessment and manage the legionella risks when you:
reinstate a water system or start using it again
restart some types of air conditioning units
If the water system is still used regularly, maintain the appropriate measures to prevent legionella growth.
