As temperatures rise, so does the risk of Legionella bacteria growing in your water systems. Summer is the perfect time to review your water tank maintenance and make sure your property is protected. Whether you’re a landlord, letting agent or business owner, understanding how to prevent Legionella is key to keeping people safe and staying compliant.
Why Summer Increases Legionella Risk
Legionella bacteria thrive in warm, stagnant water, typically between 20°C and 45°C. This makes the summer months a higher risk period, especially for properties with underused taps or poorly maintained water tanks. If left unchecked, Legionella can lead to Legionnaires' disease, a serious form of pneumonia.
Key Signs Your Water System Needs Attention
- Tanks are not insulated - Hot weather can raise water temperatures, encouraging bacterial growth
- The system hasn’t been used regularly - Empty or low-use properties are especially at risk
- You haven’t had a risk assessment in over a year
- Cold water isn’t cold enough - It should stay below 20°C at outlets
- Hot water takes too long to heat - It should reach at least 50°C within a minute
5 Steps to Reduce Legionella Risk This Summer
-
Book a Legionella Risk Assessment
This is the first step in identifying potential hazards in your system. Red Peak Compliance can help you spot risks before they become real problems. -
Flush Unused Outlets Weekly
Stagnant water is a breeding ground for bacteria. Flush taps, showers and outlets that aren’t in regular use. -
Clean and Inspect Water Tanks
Check for signs of debris, scale or corrosion. Tanks should be covered, insulated and easy to access for inspections. -
Check Temperature Controls
Your system should maintain hot water above 50°C and cold water below 20°C. If not, your tank or heating system may need adjusting. -
Keep Records
Record all checks, maintenance and assessments. This helps you prove compliance and spot patterns before issues develop.
Who Is Responsible?
If you’re a landlord, letting agent or duty holder, you have a legal obligation to assess and control the risk of Legionella in your properties. That applies to commercial buildings, residential lets, HMOs and even small office spaces.
