Legionella Training Online

Legionella pneumophila, or legionella bacteria – is the bacteria which causes legionellosis; legionellosis is the collective term for all of the pneumonia-like diseases caused by legionella bacteria including Legionnaires disease, Pontiac fever and Lochgoilhead fever.

If contamination occurs within water systems, these bacteria present a potentially fatal risk to health. While legionella thrives in hot water systems such as spa pools, jacuzzis and hot tubs, the bacteria can also survive at colder temperatures.  

In accordance with health and safety legislation, our online legionella course offers training to individuals on how to “contain the risk of exposure to legionella bacteria in man-made water systems.” 

Basic Legionella Management - Course Overview

Our basic legionella management course teaches delegates about the legionella bacteria, the potential risks associated with hot and cold water systems, and the measures that can be taken to prevent a legionellosis outbreak.

Our certified five-module, online course is designed for individuals with some responsibility for, or an interest in legionella management such as landlords, managers and operational staff. This course does not provide sufficient training to those ‘Responsible persons’ in charge of water supplies – for our advanced course, please see our classroom-based legionella training page. 

Our online legionella course lasts approximately 2.5 hours, and each module is followed by a set of randomised multiple-choice questions. Delegates are required to answer 85% of the questions correctly in order to pass the course. 

Upon successful completion of the online legionella training, delegates will receive a certified qualification from RoSPA.

When Is It Necessary And Who Should Take The Basic Legionella Management Course?

This course is designed for those implementing precautionary measures in the workplace, such as landlords, management and maintenance staff. The HSE ACoP L8 requires that those persons should be adequately knowledgeable and sufficiently trained in legionella management.

Although letting agents and landlords of single-dwelling properties are not required by law to produce a legionella testing certificate, they are required to complete legionella risk assessments. This course will provide the aforementioned individuals with the skills and knowledge required to complete a basic legionella risk assessment to the requirements described in HSE ACoP L8.
