Legionella risk assessments - a commercial case study

Having a Legionella risk assessment does not automatically mean you're compliant. 


If you ignore suggested actions from your Legionella risk assessment then you're putting people at risk and it's likely to cost you more money in the long-run. 

We recently helped a company become fully compliant. But sadly they learnt the hard way.

Commercial properties Legionella compliance FAQs

Is it really possible to catch Legionnaires disease in an office or other work environment?

Yes. There have been cases in the news where employees have contracted Legionnaires disease and businesses have been found to be non-compliant when it comes to Legionella. In some cases, commercial property owners aren’t aware of the requirements for Legionella risk assessments. This doesn't mean they avoid facing fines. You can catch Legionnaires disease anywhere there is water. The role of a Legionella risk assessment is to see how likely that is and reduce any risk to health. 


Are Legionella risk assessments expensive?

There are a number of things that impact the price. The size and complexity of the water system and how much a business will charge. We like to work with local companies to provide the best value for money. We offer Legionella risk assessments in Oxfordshire, Buckinghamshire, Berkshire and the surrounding areas. See the website footer for more locations. Or ask us for a quote.


If a Legionella risk assessment seems too cheap, then always question what you’re getting. Legionella risk assessments are not an off-the-shelf product and must be carried out correctly to stay compliant. If the assessor doesn’t have enough experience in water safety and hygiene, then they may not be able to help you effectively reduce the risk from Legionella. 


How long does a Legionella risk assessment take?

A Legionella risk assessment will take anywhere from hours to days. It will depend on the size and complexity of the water system in the commercial property. The best way to know how long your Legionella risk assessment will take is to get a quote.


Are property managers responsible for health and safety?

If you use a property or facilities management company, then you need to check your agreement with them. In some cases a management company may take care of Legionella risk assessments, but that's not always the case. If it isn’t clear who is responsible for arranging Legionella risk assessments, then legal duty will fall to the person with ultimate control of the building. 


Do I have to close my business during a Legionella risk assessment 

No, not at all. We will minimise any disruption to your usual business activities. We will need access to your water system but tell us about your business and we can discuss how we can work around you.
