Legionella Risk Assessment

Do you own or manage premises with a hot and cold water system?

If so, you have a legal obligation to conduct a robust risk assessment to identify and minimise the risks posed by exposure to legionella bacteria.



And whilst you could attempt to do it yourself, if you want your findings to be reliable, you need:

  • An in depth knowledge of the conditions under which legionella can thrive

  • A sound understanding of how the design and structure of your water system poses a threat

It means if you lack the time, skills and experience, it could be a smart move to enlist the help of a legionella control specialist to conduct the risk assessment for you.

Here’s how Key Environmental can help:

1. Comprehensive legionella risk assessments:

3. Give you peace of mind:



As you know, there are serious implications of failing to conduct a robust legionella risk assessment for your premises.

In addition to the moral obligation you have to staff, customers and the general public, if you fail to identify and rectify a risk that leads to an outbreak of Legionnaires’ Disease, there are serious implications including hefty fines or even imprisonment.

However, if you follow the findings and recommendations outlined in our risk assessment, we guarantee you’ll be compliant. And how much is that peace of mind worth to you?
