Legionella Risk

LEGIONNAIRES’ DISEASE GUIDANCE FOR LANDLORDS

AMK Safety Consultancy Limited offers comprehensive Legionella Risk Assessment services to property management companies, private landlords, commercial premises, and offices.

Legal Responsibilities of Landlords:

Health and safety laws require landlords to conduct Legionella Risk Assessments to identify and control risks that could lead to Legionnaires’ Disease. While most rental properties are generally low-risk due to regular water usage, the landlord must assess risks and implement necessary control measures to protect tenants.

Section 3(2) of the Health and Safety at Work Act 1974 (HSWA) imposes a duty of care on landlords to ensure their tenants’ safety.

Understanding Legionnaires’ Disease:

Legionnaires’ Disease is a potentially fatal pneumonia-like illness caused by inhaling water droplets contaminated with Legionella bacteria. It is not transmitted from person to person. Legionella bacteria thrive in water systems, particularly at temperatures between 20°C and 45°C, but are destroyed at 60°C or higher.

Landlord Responsibilities for Legionella Risk Assessments:

Landlords must ensure that risks associated with Legionella are properly assessed and managed for tenants, residents, and visitors. While domestic properties often require straightforward assessments, more complex commercial premises need detailed evaluations.

Key factors in a landlord’s Legionella Risk Assessment include:

Storage or circulation of water in distribution systems.
Hot water maintained between 50-60°C and cold water below 20°C.
Presence of nutrients such as rust, sludge, or scale support bacterial growth.
Assessing if any occupants are more vulnerable to infection due to age, health conditions, or weakened immune systems.

If risks are found to be minimal and control measures are in place, no further action is needed beyond periodic reviews to ensure continued compliance.

What is a Legionella Risk Assessment?

A Legionella Risk Assessment evaluates the likelihood of Legionella bacteria developing within water systems, identifying risks and recommending control measures to prevent outbreaks.

Steps in a Legionella Risk Assessment:

Site Survey:A qualified assessor inspects water systems, including hot and cold-water tanks, showers, and cooling towers, to identify potential sources of Legionella growth.
Hazard Identification:The assessor looks for conditions that promote Legionella growth, such as stagnant water, biofilms, or temperatures between 20°C and 45°C.
Risk Evaluation:The level of risk is determined based on potential exposure to contaminated water droplets and the vulnerability of individuals in the building.
Review of Control Measures:Existing maintenance, cleaning procedures, temperature control, and water flow management are evaluated.
Remedial Actions:Recommendations are provided to mitigate risks, such as improving temperature controls, removing stagnant water areas, or modifying system design.
Monitoring and Records:Guidance is given on implementing regular monitoring, water testing, and maintaining detailed records.
Documentation:A comprehensive report summarising findings, risks, control measures, and ongoing monitoring plans is prepared.

Legionella Risk Assessments in the UK must be carried out by qualified professionals familiar with regulations such as the Health and Safety Executive’s Approved Code of Practice (ACOP) L8.

Legionella Risk Assessment Costs:

Small Commercial Properties(e.g., dental practices, offices, gyms, shops): £180 to £480, depending on system complexity.
Larger Premises(e.g., hotels, care homes, hospitals, schools): £480 to £1,580, depending on the size of the water system and associated assets.
