WMSoc Training Courses - Practical Legionella Risk Assessment Hot & Cold Water Systems Advanced - W265

Details - UPDATED FOR 2024

City & Guilds accredited

ONE-DAY COURSE:  9.15am – 4.30pm

Lunch and refreshments provided

Printed delegate materials provided


This is a practical risk assessment course suitable for risk assessors who have ideally attended a legionella risk assessment foundation course. They must also possess the required site surveying and legionella risk assessment experience that allows them to be comfortable working individually, at a level to survey and apply risk ratings on small/basic hot and cold water systems, without supervision and minimal support.  The course is designed for personnel who want to further develop their skill sets in this area.  

Candidates must have a very good working knowledge of ACoP L8 and HSG 274 Parts 2 and 3 and the control levels, documentation requirements and management structures outlined within these documents. In addition they should have a good understanding of the microbiology, history and legislation related to the control of legionella.  These aspects will only briefly be covered in an interactive revision session, to reinforce this understanding. 


Students should attend W264 Legionella Risk Assessment of Hot & Cold Water Systems Foundation, or have equivalent theoretical and practical surveying and legionella risk assessment experience. This should allow them to be comfortable working individually without supervision. This is not a course for candidates who have just started out in their risk assessing role, they should attend the previously mentioned W264 foundation course.

For those relying on previous experience rather than W264 course attendance, completion of W201 Legionella Control & the Law and W202 Legionellosis Causes and Impacts of Infection online modules will be required and are included in the course price.

Pre-reading of L8 and HSG274 parts 2 and 3 would be beneficial (available as a free download from the HSE website). 


To discuss and experience the practical aspects of carrying out a risk assessment and producing a report. This includes: 

  •  surveying a water system within the practical training area
  • audit of paperwork and site records
  • identifying non-conforming aspect of both of the above and applying prioritised, credible remedial actions
  • identifying, concluding and recording inherent, residual and ALARP risk levels and ratings
  • developing the content required in risk assessment reports 
  • producing a credible executive summary and remedial actions description
  • developing a technically correct water hygiene monitoring programme

This is achieved by a limited amount of PowerPoint presentation, but primarily through group exercises and classroom discussions on the findings of the exercises. Therefore, candidates should be prepared for the course to be very interactive and that they will be required to be collaborative and provide their contributions to the discussions arising on the day. 


Revision session on current requirements for an effective and compliant legionella control programme.

Group exercises based around surveying water systems plant and legionella control procedures and then applying risk ratings to these findings.

The day includes students working in the Practical Training Area where they will be required to:

  • survey a working water system and extracts from the documentation supplied by site 
  • interview the responsible person 
  • identify system non-conformances 
  • apply the appropriate risk ratings 
  • issue an executive summary of their findings, including suggested remedial actions. 

The justification of how they have developed those remedial action plans and assigned their risk ratings will form the basis for the scoring of the assessment.

The student's ability to follow instructions, work by themselves, work safely in respect to their own safety and the safety of others and account for their actions in a clear unambiguous written record will be observed and assessed. 


The course will be solely assessed on the practical surveying and report writing exercise as final examination. Therefore it should be understood that a retake cannot be undertaken, and re-attendance on a full course will be required, if a successful pass rate is not obtained.

6 CPD points awarded.

Electronic certificates will be sent directly to successful candidates to the email address we hold on file.
