Risk Assessment

A comprehensive Legionella risk assessment is the starting point to establishing an ongoing control scheme


Stored water, drinking water, process water and closed systems are all covered by the ACoP L8 approved code of practice. It is therefore vital that these water systems are properly assessed to determine the risk of potential Legionella proliferation.

A Legionella risk assessment will enable you to choose the correct course of action for ensuring your water hygiene and management systems comply to the requirements of the ACoP L8.

Employers are required to control the risk of exposure to Legionella bacteria, which in general this requires the employer to conduct the following:

  • Identification & legionella assessment

  • Prevention or minimisation of risk from exposure to Legionella

  • Systems for the management and selection, training and competence of personnel

  • Record keeping of maintenance, temperature checks cleaning and disinfections.

ActionsActions and advice

HSE legislation requires that any property containing a water system (domestic, process or industrial) should have a Legionella risk assessment in place. This Legionella risk assessment should be reviewed every 2 years to identify any significant changes in the system design or operating conditions that may increase the risk from proliferation or exposure. Click here to learn what records should be kept and for how long.

The Legionella risk assessment will define the ongoing control scheme (temperatures checks, tank inspections, outlet flushing, water sampling, shower head cleans) and any remedial actions that may be neccessary to control the risk from Legionella exposure. The control scheme is the most important aspect in preventing the risk from Legionella exposure and ensuring compliance with the guidance.
