Official Course Overview

Legionella Training Written Line by Line Against Irish Law

Legionella bacteria never announce themselves. They multiply quietly in warm, stagnant water, inside a calorifier set too low, a shower head nobody descaled, an outlet in a vacant property that has not run for weeks. Then someone inhales a fine mist of droplets, and what looked like a plumbing detail becomes Legionnaires' disease, a severe pneumonia that puts people in hospital. 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.

Five modules walk you through the whole subject from a duty holder's point of view: what legionella is and how people develop Legionnaires' disease, your legal responsibilities under Irish law, the man-made water systems that pose risks, from cooling towers to hot and cold water systems and spa pools, how to carry out a legionella risk assessment step by step, and the control measures that keep water safe, from storage temperatures and weekly flushing to cleaning, disinfection and record keeping. Real systems and clear photographs keep every lesson practical.

Built on
  • Safety, Health and Welfare at Work Act 2005
  • Chemical Agents Regulations 2001
  • Code of Practice for the Prevention and Control of Legionellosis

The three rules that shape your training

  1. Sections 8 and 19

    Duty holders must assess and control the risk

    The Safety, Health and Welfare at Work Act 2005 requires every employer and person in control of a premises to identify hazards, assess risks and put controls in place, and to provide the information, instruction and training people need to stay safe. Water systems that can expose people to legionella fall squarely under that duty.

  2. S.I. No. 619 of 2001

    Legionella is a hazardous agent

    The Safety, Health and Welfare at Work (Chemical Agents) Regulations 2001 require duty holders to assess the risks from hazardous agents in the workplace, including biological agents such as legionella bacteria, and to prevent or adequately control exposure using measures that are proportionate to the risk.

  3. Code of Practice

    Legionellosis prevention has a rulebook

    The Code of Practice for the Prevention and Control of Legionellosis sets out how duty holders comply in practice: a legionella risk assessment carried out by a competent person, a written scheme for controlling the risks, registration of cooling towers and evaporative condensers with the local authority, and reporting work related cases of legionellosis to the Health and Safety Authority.

Course Curriculum

Your Legionella Training, module by module

Five focused modules take you from what legionella actually is and how people develop Legionnaires' disease, through the laws that apply to your premises and the water systems that pose risks, to the five step risk assessment and the control measures that keep water safe, from storage temperatures and flushing routines to cleaning, disinfection and record keeping. Everything is written in simple, clear language, built around 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 it all counts towards your legionella training certificate.

5 Focused modules, 79 lessons
2 hrs Typical time to finish
15 Exam questions, 75% to pass
3 years Certificate validity

Stop and start whenever you like. Progress saves automatically, retakes are always free, and the whole legionella course is CPD Certified, RoSPA Approved and aligned with Irish health and safety law.

  1. Introduction to Legionella and Legionnaires' Disease

    Foundations

    What legionella is and where it comes from, the water systems that put people at risk, and how people contract Legionnaires' disease by inhaling fine droplets of contaminated water. You will learn the symptoms to watch for, who is most at risk, from people with compromised immune systems to older people and smokers, how the disease is diagnosed and treated, and real case studies that show how quickly an unmanaged water system can turn into an outbreak.

  2. Legal Responsibilities of Duty Holders

    The Law

    The Irish legal framework in plain language: the Safety, Health and Welfare at Work Act 2005 and the duties it places on employers and anyone in control of premises, the Chemical Agents Regulations 2001 that cover hazardous agents such as legionella bacteria, and the Code of Practice for the Prevention and Control of Legionellosis. You will learn who counts as a duty holder, the duties of designers, manufacturers, installers and employees, when cooling towers and evaporative condensers must be registered with the local authority, and when a case of legionellosis must be reported to the Health and Safety Authority.

  3. Legionella Risks in Man-Made Water Systems

    Recognition

    The systems on real premises where legionella multiplies: evaporative cooling systems that release aerosols into the air, hot and cold water systems with calorifiers, taps and showers, and other risk systems such as spa pools, misting devices, vehicle washes and decorative fountains. You will learn the conditions bacteria love, water sitting between 20°C and 45°C, stagnation, and sludge, rust and scale that feed microbial growth, and how to weigh up the risk each system poses to the people who use your premises.

  4. Risk Assessment for Legionella

    Assessment

    Who has the duty to carry out a legionella risk assessment and what a competent person looks like, from an experienced supplier to a specialist consultant. Then the five steps in order: identify the hazards posed by your water systems, using schematic diagrams to see which parts pose risks, determine who might be harmed and how, evaluate the risks and implement controls, record your findings, and monitor, review and update the assessment, at least once a year and sooner whenever systems or the premises change.

  5. Controlling Legionella Risks

    Action

    The control measures that keep water systems safe day after day: the role of the competent person and keeping staffing and knowledge up to date, design and commissioning of water systems by competent specialists, the written scheme for controlling legionella risks, storing hot water at 60°C, flushing outlets weekly in vacant properties, avoiding materials that feed bacterial growth, cleaning and disinfecting systems, monitoring, inspection and record keeping, and training and communication for everyone involved. Finish this module and the final exam unlocks: pass it and your certificate downloads straight away.

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.

What does the Legionella Training Course actually cover?

Legionella bacteria never announce themselves. They multiply quietly in warm, stagnant water, inside a calorifier set too low, a shower head nobody descaled, an outlet in a vacant property that has not run for weeks. Then someone inhales a fine mist of droplets, and what looked like a plumbing detail becomes Legionnaires' disease, a severe pneumonia that puts people in hospital. The course takes that risk apart step by step, then shows you the controls that remove it. Five modules walk you through the whole subject from a duty holder's point of view: what legionella is and how people develop Legionnaires' disease, your legal responsibilities under Irish law, the man-made water systems that pose risks, from cooling towers to hot and cold water systems and spa pools, how to carry out a legionella risk assessment step by step, and the control measures that keep water safe, from storage temperatures and weekly flushing to cleaning, disinfection and record keeping. Real systems and clear photographs keep every lesson practical.

Is Legionella Training a legal requirement in Ireland?

Sections 8 and 19 is the short answer. The Safety, Health and Welfare at Work Act 2005 requires every employer and person in control of a premises to identify hazards, assess risks and put controls in place, and to provide the information, instruction and training people need to stay safe. Water systems that can expose people to legionella fall squarely under that duty. Our course is written directly against that wording, which is why it satisfies the duty rather than merely gesturing at it.

Who needs to take the Legionella Training Course?

Anyone in charge of premises with water systems that could pose legionella risks: employers, self-employed people, landlords, letting agents, facilities and maintenance managers, and building owners in settings like offices, hotels, gyms, care homes, schools and rental properties. It is written at an introductory level, so no previous knowledge is required.

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.

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.

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.

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.

How long is the certificate valid in Ireland?

Renewal is recommended every three years, or sooner if your water systems, premises 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.

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.

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.

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).

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.

What does the legionella training course cover?

Everything a duty holder needs to understand, assess and control legionella risks, across five modules: what legionella is, how people contract Legionnaires' disease and who is most at risk; the legal responsibilities of duty holders 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; the man-made water systems that pose risks, from evaporative cooling systems to hot and cold water systems and spa pools; the five step legionella risk assessment; and the control measures that keep water systems safe, from storage temperatures and flushing to cleaning, disinfection, monitoring and record keeping.

Is legionella training required by law in Ireland?

Duty holders in Ireland must identify and control biological hazards such as legionella under the Safety, Health and Welfare at Work Act 2005 and the Chemical Agents Regulations 2001, and the Code of Practice for the Prevention and Control of Legionellosis sets out how: a risk assessment, a written control scheme and competent, trained people running it. The Act also requires employers to provide the information, instruction and training staff need to work safely. This course delivers and proves exactly that training.

How many questions does the exam have and what do I need to pass?

The final test has 15 multiple choice questions drawn from all five modules, each with three answers to choose from. The pass mark is 75 percent, which means 12 correct answers out of 15. There is no clock running, and if the first attempt falls short you can revisit any module and retake the exam free of charge as many times as you need. The certificate is issued the moment you pass.

How fast do I get the legionella training certificate?

Instantly. The moment you pass the final test, the certificate is generated automatically, emailed to your inbox and saved on the Certificates page of your account. Most learners go from enrolment to a verifiable certificate in a single sitting of about 2 hours, and the certificate stays valid for 3 years.

Who should take the legionella training course?

Anyone in control of premises with water systems, no matter how big or small: employers, self-employed people, landlords and letting agents, facilities and maintenance teams, and owners or managers of hotels, gyms, spas, care homes, schools and offices. If your premises has hot and cold water systems, showers, a cooling tower, a spa pool or even decorative fountains, you are a duty holder and this course explains exactly what the law expects from you.

Does the course cover landlords and vacant properties?

Yes. Landlords and letting agents are duty holders too, and the course covers the risks in domestic hot and cold water systems, why stagnant water in vacant properties is one of the biggest risk factors, the weekly flushing routine that keeps outlets safe, sensible temperature settings for calorifiers and taps, and the simple checks and records that keep a rental property compliant between tenancies.

Can I do the course from Dublin, Cork, Galway, Limerick or anywhere else in Ireland?

Yes. The training is delivered 100 percent online, so a landlord in Tralee gets exactly the same accredited course and the same recognised certificate as a facilities manager in Dublin. Start it on a laptop at work, continue on your phone on the commute and finish at home; progress follows you automatically between devices, and the certificate is accepted by employers across Ireland, the UK and the EU.

How do I train a full team and what discounts apply?

Checkout applies the discounts automatically, no codes needed: 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).
