WMSoc Training Courses - Legionella Control & Management for Dutyholders and Responsible Persons - Hot & Cold Water Systems - W250


City & Guilds accredited

ONE-DAY COURSE:  9.15am – 5pm

Lunch and refreshments provided

Printed delegate materials provided



This course is designed for duty holders, legionella responsible persons, and those who are responsible for, use or operate, any water system that is capable of growing and emitting legionella bacteria. The course will provide information on the main aspects of legionella and Legionnaires disease, its implications and the need for controls. 

As well as duty holders and responsible persons, delegates are likely to include factory, site and office managers, and supervisory staff. Site engineers, facilities managers and plant operators may also find the course useful especially if they have had limited training in legionella and the need for its control.


The course assumes no previous knowledge of Legionella, but delegates would benefit by downloading The Approved Code of Practice (L8) and HSG274 Parts 2&3 from the HSE website (free PDF download - click here) and familiarising themselves with these documents.



  • To give detailed legionella training to owners and operators of hot and cold water, and other (not evaporative cooling - see course W251) systems so they understand how to meet the demands of health and safety legislation (and so operate their water systems safely and within the law).
  • To gain an understanding of the management of risk and the degree of control necessary in the most common systems, and an outline of the requirements of the control of other systems, including commercial and industrial water systems (and where that information can be obtained).
  • To ensure the delegates understand how to deal with the regulators, what to expect during an inspection, how to prepare for a visit from them, what powers they have and the types of enforcement they can take.



  • Background, history, microbiology and legislation relating to legionella and Legionnaires disease.
  • Health and Safety law and the hierarchy of Acts, Regulations, Approved Codes of Practice and Legionella guidance, including ACoP the control of legionella bacteria in water systems L8, and technical guidance HSG274 part 2 the control of legionella bacteria in hot and cold water systems and HSG274 part 3 the control of legionella bacteria in other risk systems.
  • Compliance requirements: legionella risk assessment and competence, written scheme and management and control.
  • Selection of sub-contractors
  • Specific controls in domestic hot and cold water systems in the workplace
