Easily identify and control risk factors and keep your facility safe and disease-free
Published 4 Jun 2021
A Legionella risk assessment is a tool used by landlords, employers, and property managers to identify Legionella-related risk factors in a property, workplace, or facility and to control the risks of Legionnaires’ disease, a pneumonia-like illness caused by Legionella. Legionella risk assessment is a legal requirement for landlords and employers.
This Legionella Risk Assessment Template can be used by the Legionella-responsible person to assess the premises of a property. This template has been built according to the Residential Landlords Association (RLA) Legionnaires Disease Risk Assessment & Guidelines. Use this template to record cold and hot water temperatures, check if maintained properly, and evaluate if air conditioning and water systems are clean and disinfected.

Property managers or competent individuals responsible for the control of Legionella bacteria should ensure a safe and disease-free workplace or residential accommodation for occupants. Legionella risk assessment templates aim to guide assessors perform thorough inspections of water systems and prevent the growth of Legionella bacteria which can cause serious harm or fatality from Legionnaires’ disease.
According to the Health and Safety Executive (HSE), anyone with the necessary skills, knowledge, and experience to manage health and safety can do a Legionella risk assessment.
Most landlords, employers, and property managers can do a Legionella risk assessment on their own. But if they are not comfortable with doing it on their own or if they are unable to do the Legionella risk assessment, they can appoint someone else to do it on their behalf.
Though the HSE has not given a specific timeframe for how often Legionella risk assessments need to be done, based on the Approved Code of Practice for Legionnaires’ disease (ACOP L8), records of significant findings must be kept for the period that they are current and at least 2 years after the Legionella risk assessment.
While recording significant findings during Legionella risk assessments is only a legal requirement for UK employers with five or more employees, given that such records of risk assessments are required to be retained for at least 2 years, it is recommended that Legionella risk assessments are reviewed and, should there be changes that could affect the risk, be done at least every 2 years.
Landlords, employers, and property managers can use the following steps as a guide in performing a Legionella risk assessment and in managing Legionella risks:
The first step in carrying out a Legionella risk assessment is to determine if there is risk. Check if any of the top 3 Legionella-related risk factors are present. Also check for other Legionella-related risk factors such as:
If there is currently no risk, determine if there is a possibility that a risk will occur. If there is no reasonably foreseeable risk, according to the HSE, the Legionella risk assessment is complete.
If there is risk, determine the risk level. If the risk level is low and risk is being properly managed to comply with law, according to the HSE, the Legionella risk assessment is complete. Indications that the Legionella risk level is low (based on examples given by the HSE):
For domestic hot and cold water systems, though Legionella testing is not usually required, it can be helpful in cases where control measures do not seem to be effective. To test for Legionella, the HSE recommends doing the following:
Aside from cases where control measures do not seem to be effective, Legionella testing is typically only carried out for cooling tower systems, though it is also recommended for other open systems such as evaporative condensers and spa pools. Additionally, the HSE states that these systems should be tested for Legionella at least quarterly. However, take note that UK law does not require a Legionella test certificate, nor does the HSE recognize it.
Under the Notification of Cooling Towers and Evaporative Condensers Regulations 1992 (NCTEC), the local authority must be notified in writing if there is a cooling tower or evaporative condenser on site and details about where it is located should be included. The local authority must also be notified when such devices are no longer in use.
Under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR), cases of Legionellosis (Legionnaires’ disease) in employees who have worked on cooling towers or on hot and cold water systems that are likely to be contaminated with Legionella must be reported.
For properties that are left vacant, water should not be allowed to stagnate within the water system and outlets on hot and cold water systems should be used at least once a week.
According to ACOP L8, a Legionella risk assessment should be reviewed when there is reason to believe that it is no longer valid. Examples of when a Legionella risk assessment should be reviewed (taken from HSE guidance for ACOP L8):
In Michigan, Flint’s water crisis spawned one of the largest outbreaks of Legionnaires’ disease in U.S. history. Here are the most common factors that make a facility more susceptible to Legionella bacteria and how landlords, employers, and property managers can effectively control them:
Dead legs are improperly removed or rarely used outlet pipes without regular water flow, and such redundancy in pipeline systems lead to stagnant water, a primary breeding ground for Legionella. For example, if a sink has been removed and the piping that once led to it has been capped off, this creates an area for water to stagnate. Easily manage redundant pipework by surveying the hot and cold water system and updating its full schematic diagram, including the water flow, water treatment program, and a written scheme for controlling Legionella.
Another condition for legionella to rapidly multiply is the lack of residual disinfectants like chlorine in cold water storage tanks. Routine cleaning and disinfection of cooling towers and the hot and cold water system should take place at least once in every six months. The procedure should cover the initial concentration of oxidizing biocide in use for the pre- and post-cleaning disinfection stages, contact time for each stage, and methods for carrying out the cleaning, including the removal of packing.
The temperature of hot and cold tap water should remain 50 degrees Celsius (122°F) or above and 20 degrees Celsius (68°F) or below, respectively, while the water temperature inside the boiler should be kept at or above 60 degrees Celsius (140°F). Legionella exponentially grows in warm water temperatures, ranging from 25-42 degrees Celsius (77°-108°F). Proactively guard the premises against Legionnaires’ disease by installing temperature sensors.
Property managers can effectively prevent Legionellosis in their premises by regularly maintaining the condition, cleanliness, and correct temperature of hot and cold water systems. Turn your paper Legionella risk assessment forms into digital templates and record your significant findings with the convenience of using iAuditor, the world’s most powerful mobile risk assessment app.
This legionnaires risk assessment template is according to the Health and Safety Executive (HSE) Control of Legionella Bacteria in Water Systems for auditing cooling towers. Use this template to efficiently inspect an unlimited number of cooling towers and evaluate a site’s water treatment program and written scheme for controlling the risk from exposure to legionella bacteria. The landlord or any competent legionella-responsible person can easily customize this template according to the design and construction, operation and maintenance, monitoring, and cleaning and disinfection of their cooling tower systems.
This legionella risk assessment form is based on the Centers for Disease Control and Prevention (CDC) Legionella Environmental Assessment Form used to gain a thorough understanding of a facility’s water systems and assist facility management with minimizing the risk of legionellosis. This smart form automatically shows you required questions according to previous answers such as “Does occupancy vary throughout the year?” and if YES is answered, the next question would be for selecting the season(s) with the lowest occupancy.
A health and safety risk assessment template is used to help businesses identify on site hazards before things go wrong. Site managers and safety officers can use this template to identify potential and existing hazards, evaluate each hazard’s risk level, and provide preventive control measures. Monitor and review planned control measures and advise if further measures are required. Lastly, provide overall recommendations to avoid and manage risk hazards. Capture photos of commonly ignored hazards and assign actions to notify your managers of immediate risks.
