Legionella Risk Assessments

Legionella risk assessments are a vital part of ensuring the safety of any water system within residential and commercial properties. At Greenleaf Assessments Ltd, we carry out comprehensive, compliant inspections to help landlords, property managers, and business owners meet their legal responsibilities and protect occupants from the risks of Legionnaires’ disease.

Legionella is a type of bacteria found in natural water sources, but it can grow and spread in man-made systems such as hot and cold water tanks, taps, showers, and cooling towers. When inhaled in water droplets (such as from a shower or tap spray), it can cause Legionnaires’ disease—a potentially fatal form of pneumonia.

Under UK Health and Safety Law, all landlords and duty holders must assess and control the risk of Legionella in their properties. This includes:

• Domestic landlords (even for a single rental property)
   
• Commercial property owners
   
• Letting agents and housing providers
   
• Businesses and organisations with water systems
   

• A physical inspection of the water system
   
• Identification of potential Legionella breeding areas
   
• Temperature checks and system performance review
   
• A detailed, easy-to-understand report
   
• Practical recommendations to reduce or eliminate risks
   

We assess typical risk areas such as:

• Cold water storage tanks
   
• Hot water cylinders
   
• Taps, showers, and dead legs in plumbing
   
• Little-used outlets (e.g. in vacant rooms or extensions)
   

• Experienced and qualified assessors
   
• Fast and efficient service with clear, actionable reports
   
• Ideal for landlords, letting agents, and commercial operators
   

Whether you're managing a single rental flat or a portfolio of commercial units, Greenleaf Assessments Ltd provides the confidence that your water systems are safe, compliant, and risk-free.
