We are committed to ensure our tenants are not exposed to health risks from our water systems—this includes the risk of Legionella, the bacteria that causes Legionnaires’ disease.
Legionella can grow in domestic hot and cold water systems, especially where water is stagnant or temperatures are poorly controlled. Inhaling contaminated water droplets—such as from showers or communal systems—can lead to serious illness.
Legionella Risk Assessments (LRAs)
A Legionella risk assessment is a legal requirement for anyone who manages or controls premises with water systems. It is our purpose to identify and evaluate potential sources of Legionella bacteria growth and exposure.
By doing this we complete LRAs on a risk based strategy which is outlined in our Water Management Policy below.
Legionella Guidance
Legionella thrives in:
• Hot and cold water systems
• Showers and taps
• Cooling towers and air conditioning units
• Spa pools and hot tubs
• Water storage tanks
• Decorative fountains and water features
• People over 50
• Smokers and heavy drinkers
• Individuals with weakened immune systems or chronic illnesses
• Residents in care homes or hospitals
1. Risk Assessment
• Identify potential sources of Legionella.
• Assess who may be at risk.
• Review regularly and update after any changes.
2. Temperature Control
• Cold water: Keep below 20°C
• Hot water: Store at 60°C, distribute at 50°C minimum
• Avoid temperatures between 20–45°C, where bacteria can grow
3. Flushing Unused Outlets
• Flush all seldom-used taps and showers at least weekly. This is especially important in unoccupied buildings or guest rooms.
4. Cleaning and Disinfection
• Clean shower heads and hoses every 3 months.
• Descale and disinfect regularly.
• Inspect and clean tanks, filters, and strainers.
5. Record Keeping
• Log water temperatures, flushing schedules, and maintenance activities.
• Keep inspection and testing records for at least 5 years.
