This City & Guilds Accredited Legionella Awareness course is designed to cover basic training requirements for any personnel involved in hot and cold water supplies. It covers the basics of the Approved Code of Practice (Acop) L8 guidance on Legionnaires Disease and HSG274, as well as covering what Legionella is and what effects Legionella disease can cause to a person.

We offer this Legionella Awareness course in 4 different delivery methods,

Classroom, Virtual Classroom on onsite delivery is suitable for anyone involved in water systems hygiene control, who may be exposed to aerosols or needs a refresher on Legionella guidance and regulations. This delivery will also focus on the key aspects of legionella bacteria control

Legionella Responsible Person Training

Hydro-X Training offers a City & Guilds Accredited responsible person course designed for delegates that are involved in the management of Legionella bacteria in hot and cold water systems, or those who may be appointed as Legionella Responsible Person, Legionella Deputy Responsible Person or as a Legionella Duty Holder.

This course goes deeper into the legislation and guidance than the Awareness Course covering the importance of the Heath and Safety at Work Act 1974, RIDDOR, COSHH, ACop L8, and HSG274. Furthermore, this course covers what roles and responsibilities Legionella’s Responsible person would have and looks at the risk of the moral, legal, and financial implications that come as part of poor Legionella management.

This does cover risk assessments of Legionella, with the aim to minimize the risk of the bacteria in hot and cold water systems. For a more in-depth Risk Assessment course, we offer a course that covers hot and cold water systems.

This additional course covers additional legislation such as Consultation with Employees Regulations 1996 and Notification of Cooling Towers and Evaporative Condenser Regs.


Classroom and onsite sessions are done back to back with the Responsible Persons Course, however, if using the virtual classroom method, you need to book BOTH the Responsible Person session AND the cooling towers session to receive a City & Guild Accredited Programme Certificate for Hot and Cold Systems with Cooling Towers.

What is Legionnaires Disease and how can you get it?

Legionnaires disease is a form of lung disease that can range from a severe form of pneumonia to the milder Pontiac fever, which is caused by the water bourne bacteria Legionella. This disease is easily spread into man-made water systems, including cooling towers and pipes. 

At the correct temperatures, Legionella bacteria can multiply very quickly, and furthermore are easily spread through droplets (aerosols) in the air, with common sources including spa pools and hot & cold water systems.

Whilst Legionella disease isn’t contagious between humans it is easily spread through infected water systems. Doing a Legionella Training course with Hydro-X will cover risk management and how to become a competent person maintaining water systems and minimising the risk of Legionnaires Disease. 

The legislation covered in our Legionella courses 

All our accredited Legionella training courses cover all the essential legislation so you have a full understanding of the legal side of water management, including ACoP L8 Compliance, HSG 274 Guidance and HTM 04 – 01

Why do you need to complete an ACoP L8 Course? 

The ACoP L8 (Approved Code of practice (ACoP) L8) is the UK’s primary legionella bacteria control document, approved by HSE. It offers guidance on controlling the bacteria in water systems. 

The ACoP is supported by HSG274 which provides additional guidance and practical advice on the control in different areas of the water hygiene industry regarding Legionella.   

These pieces of guidance work in conjunction with the Health and Safety at Work Act 1974 and the Control of Substances  Hazardous to Health 2002. 

ACoP L8 as a piece of guidance isn’t compulsory to follow, however, it is important to be aware that ACoPs have special legal status:

“If you are prosecuted for breach of health and safety law, and it is proved that you did not follow the relevant provisions of the Code, you will need to show that you have complied with the law in some other way or a Court will find you at fault.”

Do you legally need a legionella training course?

There is no legal requirement to comply with the Approved Code of Practice ACoP L8 and HSG 274. In the same way, the law does not state to comply with the Highway Code. Therefore, it is not a legal requirement to go through a legionella training course.

Although you don’t legally need to take a legionella training course, you must be able to prove your understanding of your legal responsibilities. In addition, you will be able to demonstrate that you have the appropriate level of knowledge to be competent to do the job required. It is nearly impossible to be able to show this without having the training to ensure you reach those levels. Furthermore, the ACoP L8 guidelines, issued by the HSE, mention the need for regular refresher courses.
