Building closure or reduced occupancy can increase the risks of Legionnaires’ disease.

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 was closed or has reduced occupancy during the coronavirus (COVID-19) outbreak, water system stagnation can occur due to lack of use, increasing the risks of Legionnaires’ disease. This may particularly affect:

• Hot and cold water systems
• Cooling towers and evaporative condensers
