Legionella Advanced Awareness Training - Target Audience

Legionellosis is the collective name given to the pneumonia-like illness caused by legionella bacteria. This includes the potentially fatal legionnaires’ disease, as well as the similar but less serious conditions.

Any water system that has the right environmental conditions can become a source of legionella bacteria. Cooling towers, evaporative condensers and whirlpool spas are particularly susceptible but all water systems can pose a risk.

This online course is aimed at legionella duty holders, nominated legionella responsible persons and those with operational responsibility for the management of the services of a building. It meets the training and awareness requirements of relevant legislation and regulations including L8, HSG 274, HTM 04-01, COSHH and the Health and Safety at Work Act 1974.

Meets the requirements of HSE, CHAS, SafeContractor, ConstructionLine, Exor, SMAS and other SSIPs.

Advanced Legionella Training - Course Structure

The course comprises 5 interactive modules and a final assessment. Links to recommended reading and additional resources may be provided within the training modules. These links are not mandatory and will not be tested for in the final assessment.


It takes approximately 2 hours to complete the course in full. This can be spread out over multiple sessions or completed in a single session. There is no time limit for completion.


All candidates must complete a multiple choice assessment after working through the training material. The candidate will be asked 20 multiple choice questions, randomly chosen from a larger question pool, and need to answer a minimum of 15 correctly to pass. Candidates will be given instant feedback after completing the assessment stating whether they have passed or failed. The assessment can be re-taken as many times as is required to pass at no additional cost.
