Managing rental properties involves many responsibilities, and one critical area is ensuring water safety. Legionella bacteria can pose serious health risks if not properly controlled. Understanding and following legionella risk assessment guidelines is essential for landlords to protect tenants and comply with legal requirements. In this post, I will guide you through the key points of landlord legionella compliance, practical steps to take, and how to maintain a safe water system.


Understanding Landlord Legionella Compliance


Legionella bacteria thrive in water systems that are not properly maintained. These bacteria can cause Legionnaires' disease, a severe form of pneumonia. As a landlord, you have a legal duty to manage the risk of exposure to legionella in your properties. This responsibility includes carrying out regular risk assessments and taking action to control any identified risks.


Key points about landlord legionella compliance:


  • Legal duty: Landlords must comply with health and safety regulations related to legionella control.

  • Risk assessment: A thorough inspection of water systems to identify potential legionella hazards.

  • Control measures: Implementing steps to reduce or eliminate risks, such as temperature control and system cleaning.

  • Record keeping: Documenting assessments, actions taken, and maintenance schedules.


By following these guidelines, you reduce the risk of legionella growth and protect your tenants' health.

Key Steps in Conducting a Legionella Risk Assessment


A legionella risk assessment involves a detailed review of your property's water systems. Here are the main steps to follow:


  1. Identify water systems

    Locate all water storage tanks, pipes, taps, showers, and cooling systems that could harbour legionella.


  2. Assess the risk of legionella growth

    Check for conditions that encourage bacteria growth, such as stagnant water, temperatures between 20°C and 45°C, and the presence of rust or scale.


  3. Evaluate the risk of exposure

    Consider how tenants or visitors might come into contact with contaminated water, especially through aerosols from showers or taps.


  4. Decide on control measures

    Based on the risk level, decide what actions are necessary. This might include flushing unused outlets, cleaning tanks, or adjusting water temperatures.


  5. Record findings and actions

    Keep a written record of the assessment, risks found, and control measures implemented.


  6. Review and update regularly

    Risk assessments should be reviewed periodically or when changes occur in the water system or property use.


Using a professional service can help ensure the assessment is thorough and compliant with current regulations.


How often do we need a legionella risk assessment?


The frequency of legionella risk assessments depends on the property's size, complexity, and risk level. Generally, landlords should:


  • Conduct a full risk assessment at least every two years.

  • Review the assessment annually or sooner if there are changes to the water system or building use.

  • Carry out regular monitoring and maintenance between assessments to keep risks under control.


If the property has a low-risk water system, assessments might be less frequent, but regular checks remain essential. High-risk properties, such as those with complex water systems or vulnerable occupants, require more frequent assessments and monitoring.


Practical Tips for Managing Legionella Risks in Rental Properties


Managing legionella risks can seem daunting, but breaking it down into manageable tasks helps. Here are some practical tips:


  • Keep water temperatures outside the danger zone

Hot water should be stored above 60°C and distributed at a minimum of 50°C. Cold water should be kept below 20°C.


  • Avoid water stagnation

Regularly flush taps and showers, especially in unused rooms or during tenant turnover.


  • Maintain water systems

Clean and descale tanks, pipes, and showerheads regularly to prevent biofilm buildup.


  • Install thermostatic mixing valves

These devices help control water temperature safely, reducing scalding risk while preventing legionella growth.


  • Train staff or contractors

Ensure anyone involved in property maintenance understands legionella risks and control measures.


  • Keep detailed records

Document all inspections, maintenance, and actions taken to demonstrate compliance.


By following these steps, you can effectively manage legionella risks and provide a safe environment for tenants.
