Landlords’ Guide: Best Practices for Legionella Control
As a landlord, ensuring your property is safe for tenants goes far beyond fixing leaky taps or broken boilers. One of the most critical areas that often goes overlooked is legionella control. Legionella bacteria, the cause of Legionnaires’ disease, can thrive in poorly maintained water systems, putting tenants at risk and landlords in legal hot water.
This guide will walk you through everything you need to know about legionella control as a landlord—why it matters, what the law requires, and practical steps landlords can take to protect tenants and stay compliant.

Why Legionella Control Matters
Legionella bacteria can grow in water systems, particularly where water is stored or recirculated at temperatures between 20°C and 45°C. Inhalation of contaminated water droplets—often from showers, taps, or cooling systems—can lead to Legionnaires’ disease, a severe form of pneumonia.
While the risk is higher in large or complex properties, every landlord has a responsibility to manage legionella control. Ignoring it can result in serious health consequences for tenants, financial penalties, and potential legal action.
Legal Responsibilities for Landlords
The Health and Safety Executive (HSE) sets out clear guidance for landlords regarding Legionella management:
- Risk Assessment
Landlords must carry out a thorough assessment of the property’s water systems to identify potential Legionella hazards. - Implement Control Measures
Once risks are identified, landlords need to take steps to prevent bacterial growth. This may include temperature control, flushing unused outlets, and regular maintenance of tanks and pipes. - Keep Records
Documenting assessments, maintenance, and remedial actions is essential. In the event of an incident, detailed records demonstrate compliance with legal obligations. - Review Regularly
Water systems change over time, so risk assessments and control measures should be reviewed periodically, especially after renovations or if a property is vacant for an extended period.
Best Practices for Legionella Control
Following best practices helps landlords reduce risks and keep tenants safe. Here’s a practical approach:
1. Conduct Regular Risk Assessments
- Inspect all water systems, including tanks, pipes, and outlets.
- Identify areas where water may stagnate, such as unused taps, showers, or storage tanks.
- Determine which areas pose the highest legionella risk and require more frequent monitoring.
2. Maintain Safe Water Temperatures
- Hot water: Keep storage tanks at 60°C or higher, and outlets at 50°C+ to prevent bacterial growth.
- Cold water: Keep below 20°C to reduce the chance of Legionella proliferation.
- Use thermostatic mixing valves to ensure water reaches safe temperatures at the point of use.
3. Flush and Clean Water Systems
- Regularly flush outlets that are seldom used to prevent stagnation.
- Clean and disinfect tanks, showers, and taps periodically.
- Consider professional cleaning for complex systems to ensure thorough decontamination.
4. Regularly Inspect and Maintain Appliances
- Boilers, water heaters, and filtration systems should be serviced according to manufacturer guidance.
- Check for leaks, corrosion, or limescale buildup, which can encourage bacterial growth.
5. Provide Tenant Guidance
- Educate tenants on safe water use, including running taps after long periods of inactivity.
- Encourage tenants to report any issues with water temperature, quality, or pressure promptly.
6. Keep Detailed Records
- Record all risk assessments, inspections, and maintenance work.
- Note any corrective actions taken and the date they were completed.
- Keep records for future reference and to demonstrate compliance if needed.
Common Mistakes to Avoid
Even conscientious landlords can make mistakes. Common pitfalls include:
- Assuming Legionella is only a concern in large buildings
- Failing to document risk assessments or maintenance
- Neglecting unused outlets, leading to stagnation
- Relying solely on tenants to manage water safety
Avoiding these mistakes ensures your property is safe, compliant, and your tenants remain healthy.
