Legionella risk assessment

Legionella bacteria poses a potential risk to human health. Controlling its presence within water systems is a major priority in health and safety management. A legionella risk assessment will identify any shortfalls in management controls and required remedial actions, providing reassurance that the health and safety of building occupants complies with legislative requirements.   

Developing safe water systems

Undertaking a legionella risk assessment is an important first step towards achieving legislative compliance – this is where we support our clients in identifying the water systems that present a risk from legionella bacteria. The second step is to develop a water management programme where we outline the tests, checks and inspections required to achieve legislative compliance across all water systems including cooling towers, domestic hot and cold water, water features and process water. 


We have been helping clients achieve compliance with legionella and wider water quality legislation for decades. With expertise across all risk water systems and locations, from complex manufacturing sites through to commercial offices, residential, educational, retail and healthcare premises, we provide clients with the reassurance that they are maintaining safe water systems that minimise the risk presented by the legionella bacteria - the cause of Legionnaires’ disease.
