Legionella Assessment

It is a legal requirement to carry out a legionella assessment of water services in any work place or business-connected premise! Failure to carry out a legionella assessment could leave you exposed to the risk of litigation and potential prosecution. If you would like to book your Legionella risk assessment, contact us

The Health and Safety Executive is the Enforcing Body. They will undertake any prosecution under the relevant legislation regarding legionella infection.

Whether you are in a rented, services, or manager office there is still a legal obligation, as the employer, to protect employees.

Why do you need a Legionella Assessment?

Legionellosis is a very old disease and one that few people are aware of. Although its name may be unfamiliar, legionnaires’ disease is more common than many people realise. Whilst the disease is not contagious, or spread through drinking infected water, it can be spread by inhaling droplets that allow bacteria to reach the lungs directly.

This means that many people could unknowingly contract the disease. In its most serious form; Legionnaires’ disease can be fatal.

Legionella bacteria can multiply at a rapid rate. This is particularly the case in complex water systems. This is why larger public buildings are especially at risk of this bacteria presenting itself.

Legionnaires disease presents itself in the form of flu-like systems. This means it is difficult to diagnose and is often missed. Water vapour can appear and be inhaled from sources such as showers, hot tubs, taps and air conditioning units.

With the bacteria being present in all these water sources, it makes it easy to infect multiple people all at once. It also means that frequent exposure can occur. With frequent exposure to legionella bacteria, the more severe the symptoms can become.

What does the assessement cover?

A legionella assessment identifies the pipework and individual assets that make up the water system. This includes taps, showers and water tanks. These assets are then evaluated to identify the risks associated with each element. The legionella assessment is reviewed at least every two years. Unless there has been a change to the system or in management/responsible person.

There are further pieces of technical guidance and support documentation, although not all may apply to your business. These include:

  • Approved Code of Practice L8 (Fourth Edition)
  • Health Technical Memoranda 04-01 (Part A, B C & Supplement D 08)
  • Health & Safety Guidance 274 (Part 1, 2 & 3)

Legionnaires’ disease tends to affect:

  • Men more frequently than women
  • Middle-aged or the elderly more than younger people
  • People who are already ill, particularly with chest or respiratory diseases, or kidney disease
  • Smokers and heavy drinkers

    Should you be unfamiliar with the scary and serious world of health and safety but need a professional but practical assessment of your situation, I cannot recommend Emma at Walker Health and Safety highly enough. While she provided me with a detailed report, she took considerable effort to tackle my many detailed questions afterwards, all of which were delivered with professionalism and a smile. For her, nothing was too much trouble.

    We are a start-up business and came to Walker Health and Safety Services with little to no knowledge of what we needed to do ensure that our business maintained the highest standards of HSE. Emma guided us through the process and made recommendations which we implemented to ensure that we adhere to the higher of best practice and legal standards (at our request). We have been audited by two international customers who were unable to identify any shortcomings and requested sight of multiple documents all of which we were immediately able to provide. It was satisfying to be able to show that we took HSE seriously and were a well prepared and a professional organization. I definitely felt that Emma's services were money well spent and we value her advice which is always proportionate and sensible.

    The Battery Box
    As a voluntarily run recreation ground, with several sporting clubs, a social club and significant general amenity use by the public, the prospect of updating our inadequate H&S provision was daunting. Emma helped and guided us and, thankfully, told us to keep it simple but thorough. This gave us the encouragement we needed and knowing Emma was on hand as and when required was very reassuring. We would recommend her services to you: competent, professional, and understanding.

    Walker Health and Safety have helped us with getting our ISO 45001. Emma is very professional and helpful plus very friendly to work with. We get a lot of guidance and advice on improving our business system.

    It was a pleasure to work with Emma, she assisted in helping us get Chas up and running. Or should I say that she pretty much sorted it all for us, as we didn't know what we were doing. She was very knowledgeable, kind and helpful, and she brought biscuits! ;-) I would highly recommend this firm.
