What is a Legionella Risk Assessment (LRA)?

In the UK this type of specialist risk assessment is required by law and is specifically identified by the Health & Safety Executive in their Approved Code of Practice (ACOP) “Legionnaires’ disease. The control of legionella bacteria in water systems”. 

A Legionella Risk Assessment is an essential risk management process and comprises a detailed examination of the risks presented by man-made water systems, and seeks to identify and assess the risks associated with Legionnaires’ disease through exposure to legionella bacteria. 

The Legionella Risk Assessment needs to be completed every two years. Prices may vary depending on the size of the property and the number of bathrooms. Call our office for a quote.

We regret that this places yet another burden upon you, the Landlord, but we cannot ignore compliance issues, particularly in relation to Tenant Health and Safety matters.

What is Legionnaires’ Disease?

Legionnaires’ Disease is a pneumonia like illness caused by the Legionella bacteria, which can be fatal. Infection is caused by inhalation of droplets of water carrying the bacteria, which leads to infection. It is non-contagious.

The bacteria are found in the natural environment and are able to contaminate, grow and thrive in water systems if conditions are not carefully controlled to prevent their proliferation. They survive low temperatures and prosper at conditions between 20-45°C; although they are killed at high temperatures of 60°C or above.

What is my responsibility as a Landlord?

Landlords who provide residential accommodation, as the person in control of the premises or responsible for the water systems in their premises, have a legal duty to ensure that the risk of exposure of tenants to legionella is properly assessed and controlled. This duty extends to residents, guests, tenants and customers.
