Specialist Legionella Risk Assessments Maidstone

Commercial landlords are required by law to ensure that all tenants are protected from the health risks associated with legionella bacteria. Legionella is a pathogenic bacteria that causes the potentially deadly legionnaires’ disease and other pneumonia-like illnesses such as Pontiac fever and Lochgoilhead Fever.  

Legionella occurs naturally, in low numbers, in rivers, lakes and reservoirs; although does not usually pose a risk to health in such low quantities. The bacteria is also found in purpose-built water systems such as cooling towers, air conditioning systems, evaporative condensers, spa pools and hot tubs, as well as hot and cold water systems. 

Legionella thrives in temperatures between 20-45°C, and reaches optimum growth at 37°C. The bacteria becomes dormant in temperatures below 20°C and cannot survive temperatures exceeding 60°C.   

Anyone can develop legionnaires’ disease, however the elderly are most at risk, along with smokers, alcoholics, cancer patients, those with diabetes and chronic respiratory or kidney diseases.  

Residential landlords are not required to produce or obtain a legionella test certificate, however they are liable for the health and safety of their tenants and protecting them from the risk posed by legionella.
