Official Course Overview
Legionella Training for Irish Duty Holders
Legionella never knocks before it arrives. It multiplies silently in a calorifier running too cool, a shower head nobody has descaled, an outlet in an empty flat that has not been run for weeks. Then somebody breathes in a fine mist of contaminated droplets, and a forgotten plumbing detail turns into Legionnaires' disease, a pneumonia serious enough to hospitalise and sometimes to kill. This Legionella Training Course is written line by line against that law, so the certificate you download at the end stands up in a real inspection instead of just looking good in a folder.
This course hands duty holders the full toolkit. Module one explains what legionella bacteria are, how Legionnaires' disease develops and who is most vulnerable. Module two sets out your legal position under Irish law, including registering cooling towers and reporting legionellosis cases to the Health and Safety Authority. Module three tours the water systems that carry risk, from evaporative cooling systems to hot and cold water services and spa pools. Module four teaches the five step legionella risk assessment, and module five covers the controls that keep water safe: temperatures, flushing, cleaning, disinfection, monitoring and records. Real water systems and clear photographs carry every lesson.
Built on
Safety, Health and Welfare at Work Act 2005
Code of Practice for the Prevention and Control of Legionellosis
Chemical Agents Regulations 2001
The three rules that shape your training
01Section 19
Every hazard must be assessed
The Safety, Health and Welfare at Work Act 2005 requires every duty holder to identify the hazards on the premises they control, assess the risks in a written risk assessment and put controls in place. Legionella bacteria in water systems are exactly such a hazard, and the Act also demands the information, instruction and training needed to manage it.
02S.I. No. 619 of 2001
Biological agents are regulated
The Safety, Health and Welfare at Work (Chemical Agents) Regulations 2001 bring hazardous agents, legionella among them, under specific duties: assess the risk from the agent, prevent or control exposure and keep the controls working. For water systems that means temperatures, cleaning, disinfection and monitoring, done on schedule and recorded.
03HSA Code of Practice
Legionellosis control has a named standard
The Code of Practice for the Prevention and Control of Legionellosis spells out what compliance looks like in Ireland: a legionella risk assessment by a competent person, a written scheme for controlling the risks, registration of cooling towers and evaporative condensers with the local authority, and reporting of work related legionellosis cases to the Health and Safety Authority.

Course Curriculum
What the Legionella Training Course covers, module by module
Five focused modules carry you from what legionella bacteria actually are and how Legionnaires' disease develops, through the duties Irish law places on you and the water systems on your premises that carry risk, into the five step risk assessment and the control measures that keep water safe day after day. Every lesson is written in plain, friendly language, mapped to the Safety, Health and Welfare at Work Act 2005, the Chemical Agents Regulations 2001 and the Code of Practice for the Prevention and Control of Legionellosis, and every one of them moves you closer to your legionella training certificate.

01
What is Legionella?
Foundations
The bacteria itself, explained properly: where legionella lives in nature and why man-made water systems suit it so well, the temperature band between 20 and 45 degrees where it multiplies fastest, how people become infected by inhaling fine droplets of contaminated water, and the illnesses it causes, from Pontiac fever to Legionnaires' disease. You will learn the symptoms to watch for and the people most at risk: older adults, smokers, and anyone with a weakened immune system or existing lung condition.
02
Legal Responsibilities
Compliance
Exactly where you stand under Irish law: the general duties in the Safety, Health and Welfare at Work Act 2005 to assess risks and provide training, the Chemical Agents Regulations 2001 that bring biological agents such as legionella under specific control duties, and the Code of Practice for the Prevention and Control of Legionellosis, including the requirement to register cooling towers and evaporative condensers and to report work related legionellosis cases to the Health and Safety Authority. Employers, the self-employed, landlords and letting agents all carry these duties, and this module names each one.
03
Water Systems That Pose Risks
Recognition
A guided tour of the systems where legionella hides: evaporative cooling systems and cooling towers, hot and cold water services, calorifiers and storage tanks, showers and spray taps, spa pools and hot tubs, misting devices and vehicle wash systems. You will learn why stagnant water, scale, rust, sludge and biofilm turn an ordinary system into a breeding ground, and which warning signs, like dead legs, infrequently used outlets and lukewarm storage, deserve your attention first.
04
Legionella Risk Assessment
Assessment
The five step method that turns duty into practice: identify the hazards across every water system on the premises, decide who might be harmed and how, evaluate the risks and settle on precautions, record your findings in a written scheme, and review the assessment whenever systems, occupancy or the law changes. The module walks through real premises, from rental homes and offices to hotels and care settings, and shows when a competent person in-house is enough and when a specialist water treatment company is the right call.
05
Control Measures
Action
The routines that keep water safe for good: storing hot water at 60 degrees and delivering it above 50, keeping cold water below 20, flushing infrequently used outlets weekly, descaling and disinfecting shower heads, cleaning tanks and calorifiers, chlorination and other disinfection methods, monitoring temperatures on schedule and keeping the records that prove it all happened. Finish this module and the final exam unlocks: pass it and your certificate downloads straight away.

100% Real Verified Reviews
A Word Between Friends
Let's be honest with you. The internet is full of scam training websites and reviews no real customer wrote. That's why we do the opposite. Every review we have comes from a real person who took a real course with us. No fakes. No hidden feedback. They are all on Google Maps, where we can't edit or rewrite them. Be especially careful with scam websites showing reviews that appear to come from platforms such as Reviews.io. Reviews displayed on their own website may be fake, because the website owner can add, edit or fabricate them directly in the site code. Always verify the business on Google Maps instead. Today, we hold the No.1 spot across Ireland, with more real reviews than any other health and safety training company, built on 30 years of real work at honest prices. You don't have to take our word for it. Just tap the Verify us on Google button below and read every review. One last thing, friend to friend: scammers have recently created a website with a name very similar to ours. Our official name is Ireland Safety Training, while a website called "Ireland Safety Courses" has appeared in Google Ads. It is not affiliated with us in any way. Our lawyers are already collecting the necessary evidence and preparing legal proceedings. Until then, please stay careful and always verify who you are dealing with.

Questions, Answered Plainly
Legionella Training Course in Ireland, Answered Plainly
The questions workers and employers send us every week about the Legionella Training Course, the certificate and what the HSA expects, answered without the sales talk.
01
What does the Legionella Training Course actually cover?
Legionella never knocks before it arrives. It multiplies silently in a calorifier running too cool, a shower head nobody has descaled, an outlet in an empty flat that has not been run for weeks. Then somebody breathes in a fine mist of contaminated droplets, and a forgotten plumbing detail turns into Legionnaires' disease, a pneumonia serious enough to hospitalise and sometimes to kill. The course takes that risk apart step by step, then shows you the controls that remove it. This course hands duty holders the full toolkit. Module one explains what legionella bacteria are, how Legionnaires' disease develops and who is most vulnerable. Module two sets out your legal position under Irish law, including registering cooling towers and reporting legionellosis cases to the Health and Safety Authority. Module three tours the water systems that carry risk, from evaporative cooling systems to hot and cold water services and spa pools. Module four teaches the five step legionella risk assessment, and module five covers the controls that keep water safe: temperatures, flushing, cleaning, disinfection, monitoring and records. Real water systems and clear photographs carry every lesson.
02
Is Legionella Training a legal requirement in Ireland?
Section 19 is the short answer. The Safety, Health and Welfare at Work Act 2005 requires every duty holder to identify the hazards on the premises they control, assess the risks in a written risk assessment and put controls in place. Legionella bacteria in water systems are exactly such a hazard, and the Act also demands the information, instruction and training needed to manage it. Our course is written directly against that wording, which is why it satisfies the duty rather than merely gesturing at it.
03
Who needs to take the Legionella Training Course?
Everyone responsible for premises with water systems: employers, self-employed people, landlords and letting agents, facilities and maintenance managers, and the owners and managers of hotels, gyms, spas, care homes, schools and offices. The course is introductory, so nobody needs previous training to start.
04
How much does the Legionella Training Course cost?
The Legionella Training Course is €35.00 per person, and that is the full price. Team bookings get a volume discount applied automatically, and any 5 different courses cost just €100 flat (except our premium HACCP Level 3 and Health and Safety for Managers courses, which keep their own price), with one invoice and one account for all your records.
05
Can I do the Legionella Training Course online, on my phone?
Yes, the whole course is online and works on any phone, tablet or laptop. There is no classroom day and no fixed start time: register, log in and begin the Legionella Training Course whenever it suits you, at home or on a break at work. Progress saves automatically as you go.
06
How long does the Legionella Training Course take to complete?
About 2 hours, and you do not have to do it in one sitting. Progress saves as you go, so you can stop after a lesson and pick it back up on another device. Your certificate is ready to download the moment you pass.
07
What certificate do I get, and when do I receive it?
You download your Legionella Training Course certificate as a PDF the moment you pass the exam, day or night. It shows your name, the course, the date and a verification link, so an employer or inspector can confirm it in seconds. A copy stays in your account whenever you need to print it again.
08
How long is the certificate valid in Ireland?
Renewal is recommended every three years, or sooner if your water systems, your role or the law changes. We track the date for you and send a reminder before it lapses, so no certificate in your team expires without anyone noticing. The refresher is the same short online course, so staying compliant never costs a working day.
09
What happens if I fail the exam?
Nothing bad. You can retake the exam as many times as you need at no extra cost, and you can revisit any lesson before trying again. Most learners pass first time, because the questions test exactly what the course just taught.
10
Is the practical assessment included?
This course is assessed by examination rather than by a practical, because the competence it builds is judgement rather than technique. You get unlimited attempts at the exam, at no extra cost.
11
Can I book this course for my whole team?
Yes, and the platform is built for it. One company account covers every employee, shows you at a glance who has finished and who has not, stores every certificate in one place and gives you a single invoice for the lot. Group bookings get the volume discount applied automatically in your cart, and any 5 different courses cost just €100 flat (except our premium HACCP Level 3 and Health and Safety for Managers courses, which keep their own price).
12
Will employers and inspectors accept the certificate?
They do. We are an official accredited provider and the certificate carries a verification link an inspector can check in seconds. It is accepted by employers in Ireland, the UK and across the EU, and behind it stand our accreditations: Irish Legislation Aligned, QQI Assessed, CPD and RoSPA Accredited.
13
What does the legionella training course cover?
Everything a duty holder needs, across five modules: what legionella bacteria are, how Legionnaires' disease develops, its symptoms and the people most at risk; your legal responsibilities under the Safety, Health and Welfare at Work Act 2005, the Chemical Agents Regulations 2001 and the Code of Practice for the Prevention and Control of Legionellosis, including registering cooling towers and reporting cases to the Health and Safety Authority; the man-made water systems that carry risk, from evaporative cooling systems to hot and cold water services and spa pools; the five step legionella risk assessment; and the control measures that keep water safe, from storage temperatures and weekly flushing to cleaning, disinfection, monitoring and record keeping.
14
Is legionella training required by law in Ireland?
The Safety, Health and Welfare at Work Act 2005 requires duty holders to identify hazards, assess risks and provide the information, instruction and training people need to stay safe, and the Chemical Agents Regulations 2001 extend those duties to biological agents such as legionella. The Code of Practice for the Prevention and Control of Legionellosis turns the duties into a concrete standard: a risk assessment by a competent person, a written control scheme, registration of cooling towers and evaporative condensers, and reporting of work related legionellosis cases. Completing this course is that training, evidenced by a verifiable certificate.
15
How many questions does the exam have and what do I need to pass?
Fifteen multiple choice questions, three options each, drawn from all five modules. Passing needs 12 correct answers out of 15, a 75 percent pass mark. Nothing is timed, and a failed attempt costs nothing: review any module and retake the test free, as often as you need. The certificate generates the second you pass.
16
How fast do I get the legionella training certificate?
The moment the pass screen appears. The certificate is created automatically, emailed to you and stored on the Certificates page of your account, carrying a unique code any employer or inspector can verify online. Enrolment to certificate normally fits inside a single sitting of about 2 hours.
17
Who should take the legionella training course?
Anyone in control of premises with water systems, whatever the size. That means employers and the self-employed, landlords and letting agents, facilities and maintenance managers, and the people running hotels, gyms, spas, care homes, schools and offices. If a building has showers, hot and cold water systems, a cooling tower, a spa pool or misting devices, somebody is its duty holder, and this course shows that person exactly what the law expects.
18
Does the course cover rental properties and vacant periods?
Yes, thoroughly. Landlords and letting agents carry the same duty as any employer: tenants must be protected from legionella risks in the water systems of their home. The course explains why stagnant water in a vacant property is one of the biggest warning signs, the weekly flushing routine that keeps outlets safe between tenancies, sensible temperatures for calorifiers and taps, the simple records that prove compliance, and the moments when a specialist water treatment company is the right call.
19
Can I do the course from Dublin, Cork, Galway, Limerick or anywhere else in Ireland?
Yes. Delivery is 100 percent online, so a landlord in Sligo receives the identical accredited course and certificate as a facilities manager in Dublin. Begin on any device, pause when work interrupts and resume exactly where you stopped; progress syncs automatically and the certificate is recognised by employers across Ireland, the UK and the EU.
20
How do I train a whole team and what discounts apply?
The free Employer Dashboard handles the rollout: enrol staff in bulk, assign the Legionella Training Course to each person, watch completions arrive in real time and keep every certificate on one screen for the next audit. Checkout prices itself automatically, no voucher codes: 15 percent off any 3 different courses, 10 percent off 10 or more courses, 20 percent off 50 or more, and any 5 different courses for a flat 100 euro (excludes the premium HACCP Level 3 and Health and Safety for Managers courses).
