Legionella bacteria is a common and controllable bacteria that can cause several severe health conditions, including the deadly Legionnaires' disease. 


The risk should be managed by a legionella risk  assessment professional and under an on-going control scheme which include various monitoring and preventive actions bespoke to each type of water system. Due to hazards surrounding this and the potential serious risk to health, it is a legal requirement in the UK that all businesses and rented property conduct regular risk assessments and on-going preventive measures.


All businesses in the UK must comply with the authorities' legal guidance to maintain appropriate water hygiene standards. Envirisk is a leading UK legionella risk assessment  & water sampling company that can manage and assess the risk of your water system and carry out any preventive control measure to keep your water systems safe and compliant.
