The Landlord Guide to Legionella

There is a legal duty for landlords to assess and control the risk of exposure to Legionella bacteria in their properties. Follow our guidance on Legionella compliance to ensure that your property is operating compliantly and that there is no risk of your tenants catching Legionnaires’ disease – a flu-like pneumonia that can prove fatal if left untreated.

As a landlord, what must I do?

As a landlord, it is your responsibility and legal obligation to have a Legionella risk assessment carried out on every property you are in control of (source: HSE).

A Legionella risk assessment survey is a systematic examination of the potential risks presented by engineered water systems, and seeks to identify and assess the risks of exposure to Legionella bacteria from work activities and water systems.

“All water systems require a risk assessment.  A simple risk assessment may show that there are no real risks from Legionella, but if there are, implementing appropriate measures will prevent or control these risks.  The law requires simple, proportionate and practical actions to be taken, including identifying and assessing sources of risk, managing the risk, preventing or controlling the risk; and periodically checking that any control measures are effective.” (Source: HSE 2.140)
