Legionella Training Courses Guide


‘Walkies, legionella’, ‘heel, legionella’, interesting thoughts to have with the title ‘Legionella Training’. Sadly, we’re not able to train legionella to behave in a certain way: now that would be amazing if we could ‘Out, damned spot*’ [*legionella] [Macbeth, act 5, scene 1].

Hopefully, this article will be able to provide a more practical understanding when it comes to training in legionella. It is perhaps worth starting with the notion that ‘legionella courses’ have been around for decades, the requirement for suitable and sufficient training is a must in order to comply with regulations [Management of Health and Safety at Work Regulations; COSHH Regulations] and guidance documents [HSE ACOP L8; HSG274 Parts 1, 2, 3; HTM04-01, SHTM04-01 and WHTM04-01]. Over time, all documentation has been updated and knowledge of legionella [including other waterborne pathogens, i.e. Pseudomonas aeruginosa] has increased. Needless to say, ‘legionella awareness’ needs to have evolved so that it

“provides employees with suitable and sufficient information, instruction….” [HSE ACOP L8, 4th edition (2014)].

This article will look at why training is needed, the importance of identifying who needs to be trained, what type of training based on their role and responsibilities and when training is to be completed.


How Important is Legionella Training?


(Source: PHE, October 2020.)

The importance of training is a good question to ask! The reality being, how often do you hear about cases or outbreaks of ‘legionellosis’ [the term used to describe any illness caused by exposure to legionella] being reported in the news, either on the TV, radio or printed media? The fact is you hear about cases or outbreaks very rarely, they are deemed not interesting enough compared to a global pandemic or Brexit.

That’s not to say cases or outbreaks are not occurring! Pre-Pandemic, Public Health England (as they were formerly known) did monitor and report on cases of legionnaires’ disease on a monthly basis [that said, throughout 2020 only two reports were produced due to the pandemic, whereas in previous years there have been regular monthly reports]. These reports identify the sources of cases as:

  • Community acquired;
  • Travel UK;
  • Travel abroad;
  • Nosocomial.

The latest data published was October 2020 which details the number and percentage of confirmed cases of Legionellosis by category of exposure for cases with symptom onset from 1 January to 31 October 2020:

"The HSE have detailed in the ACoP L8:

“Inadequate management, lack of training, and poor communication are all contributory factors in outbreaks of legionnaires’ disease.”

Although we don’t get to hear about all these cases and outbreaks of Legionnaires’ disease, they are occurring and occasionally do make the headlines. The largest outbreak of Legionnaires’ disease in the UK occurred in Barrow-in-Furness, in August 2002 with 180 cases and seven deaths. The HSE investigation into the outbreak identified six failings, one of which related to training standards, more so the lack of training for key staff at the Council.

In October 2013 a confirmed case of Legionnaires’ disease was reported to Harlow Council, whereby the Environmental Health Officers were unable to confirm the affected employee had contracted this from the site at which he worked. Although, they did find a “serious lack of compliance” including staff receiving inadequate training in legionella. The employer was fined £1.8m.

More recent outbreaks reported include, Bournemouth, June 2019, at a spa where 39 patrons reported symptoms and nine patrons were admitted to hospital for treatment.

Do I Really Need Further Training in Legionella?


Further legionella training [and water safety] is more than likely going to be needed. The risk of legionella [and other waterborne pathogens] is one that needs continual management within an organisation.

SHTM04-01 Part B para 5.2 provides an overview for the need for ongoing training:

“The rate of change in building service technology is not great, but knowledge of harmful bacteria continues to grow and management should review the competence of staff on a regular basis, and refresher training should be given; records of training attendance would need to be maintained.”

With time, change happens… employees are promoted, some leave, new join and processes may change for documenting tasks completed. Examples of such change require a review of whether more training is needed, it might be that a new building manager has been recruited, who has had legionella awareness training with their previous employer, and this would be helpful! But training that is applicable to the new employer covering roles, governance policy arrangements, processes and documentation will be needed, for example, Legionella Responsible Person training online. A newly recruited Competent Person to assist with temperature monitoring, flushing of outlets will also require this organisational specific training, with additional elements relating to the technical aspect of their role, for example, Legionella Competent Person training.

This is not the end of training. We’ve established that initial training is a necessity and this training must be suitable and sufficient to a level that ensures they can deliver their roles and responsibilities safely and competently. The HSE have further detailed in ACoP L8 paragraph 51:

“… and receive regular refresher training. Keep records of all initial and refresher training.”

And in HSG274 Part 2 paragraph 18:

“Regular refresher training should be given and the responsible person(s) should have a clear understanding of their role and the overall health and safety management structure and policy in the organisation.”

Although, there is no indication of a frequency for ‘refresher training’ detailed in the above referenced documents. Reaching for further guidance on a frequency of training, the HSE HSG65 ‘Managing for Health and Safety details: “competence levels will drop if skills are not used on a regular basis – schedule refresher training at regular intervals.” Yet again, no frequency is detailed.

How Do I Know Who Should Receive This Training?

Identification of those involved in the management of legionella and water safety risk needs to be determined by the Water Safety Group [WSG], who have a responsibility to review training needs and ensure applicable training is then provided. Traditionally, those persons who have received training would have included:

  • Responsible Person [Water];
  • Deputy Responsible Person [Water];
  • Authorised Person [Water].

Although other persons are invariably involved with legionella / water safety precautions including [but not limited to and dependent on the size and type of the organisation]:

  • Competent Persons;
  • Head Teachers;
  • Ward / Department Managers;
  • Property / Building Managers;
  • Infection Prevention Control Managers / Nurses;
  • Cleaners / Domestics / Caretakers and Janitors;
  • Housing Scheme Managers

A few more people than you may have initially thought!

With the WSG having established their ‘training needs analysis matrix’, the process has not ended, HTM04-01 Part B paragraph 6.28 states:

“The WSG should review the competence of staff on a regular basis, and refresher training should be given; records of training attendance need to be maintained.”

One of the responsibilities of the WSG is to review training needs analysis routinely [i.e. possibly each WSG meeting], confirming those involved and whether they’ve completed the applicable training for their role; the date when the training was completed to determine when refresher training is needed; possibly including an anniversary date for training to be refreshed / updated regardless. Industry / best practice tends to have a two to three year frequency for refresher training.

This issue of the right training was touched on in the previous section: ‘the Hotel Manager will require different training compared to a Head of Maintenance or the Cleaners / Domestics’. With this in mind the training needs to be applicable to an individual’s job role, a responsible person needs to look at appropriate management training, maintenance staff need to look at appropriate operational training. It would not be appropriate for plumbers to attend a management course aimed at the responsible person, for sure the plumber will learn a lot, but the training would not have been ‘suitable and sufficient’ for their role and responsibilities.

The established Water Safety Group reviewing a training needs analysis will need to have clearly understood each person’s role and thereby select an appropriate training course for their role and have this documented.

Here at the Water Hygiene Centre, we have developed a host of training courses to cover various roles and responsibilities. To aid the Water Safety Group with the selection of what maybe the most appropriate course, we have prepared a which course is right for me matrix. The next step being documenting training, we’ve created a template ‘legionella training needs analysis which may help start the WSG with defining their own.

Traditionally our training courses have been completed face to face in a classroom environment. However, with the pandemic, we have evolved and our training courses are now available for delivery through Microsoft Teams, as well as our face-to-face sessions. These are small classes of up to nine delegates, and all training material is sent to candidates ahead of scheduled course dates.


To further compliment our training offering, e-learning is available which can be taken 24/7 at a time to suite you! At present we have the following training courses available online:

The Water Hygiene Centre also has its own Academy here you will find a selection of helpful, instruction videos on various practical tasks such as taking a temperature or flushing a little used outlet.

As an employer reading this you would be required to provide adequate information, instruction, and training to your employees. Identification of those involved with legionella awareness/water safety precautions throughout the organisation needs to be documented, with identification of any previous training completed and outlining new / refresher training required. The HSE have documented that outbreaks of Legionnaires’ disease have been attributed to poor staff training. Take this opportunity to review where you and your organisation are with legionella training.


Legionella and water safety by sector


If you are looking for particular advice around the training needs or water safety management for your industry or sector, we have created a series of industry-specific articles that you may want to consult:


I wanted an overall awareness of water safety and the key risks and responsibilities associated with my role as a manager. I wanted an understanding of what is best practice and how you achieve that. After attending the Water Hygiene Centre’s Water Safety: Management Training all my boxes were ticked and this will allow me to understand  the best way of keeping patients and staff safe when using the facilities. Really enjoyable and many thanks. It’s a 10 from me.

Andrew Donegan, Isle of Wight NHS Trust

Unfortunately due to COVID-19 restrictions it was not possible to carry out the training 'face to face' but the training was excellently presented through Microsoft Teams.  The presenter was able to answer all questions from his experience and knowledge.

Stuart Nicol, Isle of Wight NHS Trust

I attended the Water Hygiene Centre's Authorised Person course to support my new job role, I now have a better all-round understanding of water safety.

Lee Russell, CBRE

Due to moving into an Estates Officer role the Water Hygiene Centre’s management course has provided me with the knowledge I need to fulfil the role of responsible person.

Chris Jones, Serco

The Responsible Person training course is really well laid out and the delegate packs are excellent reference material.  The presenter did a great job of covering so much in one day and keeping it interactive as well as sticking to the time schedules.

Sheila Scott, University of Edinburgh

I really learnt a great deal from the Authorised Person training - which surprised me.  The presenter was very good and held my attention all day long.  It highlighted and underlined many of my concerns and gave me the confidence to proceed with remedial actions.

Steve Suckling, Cheltenham Borough Council

I was required to complete an Authorised Persons course by my employer and I was pleased to achieve my objectives by gaining a greater understanding of the laws and applicable regulations regarding water safety and the science behind why we carry out our PPM's on water systems. After attending the Water Hygiene Centre’s course I feel my objectives were achieved and I now have a greater understanding of the responsibilities towards water safety in my role

Lloyd Humby, University Hospitals Dorset

I attended the Responsible Person course to understand the role of the RP and to develop my knowledge and skills to apply this in practice to my IPC role in a healthcare environment.  Excellent training material and overall, a well organised course.

Lydia Rylance-Knight, Oxford University Hospitals NHS Foundation Trust

“As Compliance Manager within our maintenance team, I needed to ensure our contractors are working to meet current regulations and I attended the Water Hygiene Centre’s Responsible Person course to provide me with the confidence of knowledge required to fulfil my role.  My objectives were received and this has enabled me to take this knowledge back to the office and work on processes and procedures to enhance our maintenance being completed and allow us to ensure we are meeting current regulations surrounding water safety”
