Demystifying Legionella Risk: A Must-Know Guide for Landlords

In this month's discussion, we tackle a vital yet often perplexing responsibility for landlords: evaluating the risk of Legionella bacteria. Legionella was discovered after an outbreak in 1976. Those who were affected suffered from a type of pneumonia that eventually became known as Legionnaires’ disease. More recently 'The Bibby Stockholm', moored in Portland Port, Dorset, which was intended to house as many as 500 male migrants was shut dwn due to Legionella being detected in its water supply.

While many landlords are well-versed in common property risk assessments, the intricacies of Legionella assessments can be unclear, leading to potential pitfalls for unsuspecting property owners.

Understanding Legionella and its Habitat: Legionella, the bacteria responsible for Legionnaires' disease, thrives in water systems such as hot tubs and hot water tanks, with an optimal temperature range of 20-45 °C. Landlords need to pay special attention to water tanks, pipes, and shower heads, as they provide an ideal environment for Legionella growth.

Legionnaires' Disease Severity: Legionnaires' disease, a lung infection with flu-like symptoms, can escalate into a serious and life-threatening illness. Recognising the symptoms, which may include coughing, chest pains, and gastrointestinal issues, is crucial for early intervention and treatment.

Legal Obligations for Landlords: Under Section 3(2) of the Health and Safety at Work Act 1974, landlords must assess and control the risks of Legionella exposure for tenants, as stated in tenancy agreements.

Frequency of Assessments: While the law mandates periodic assessments, landlords are wise to conduct assessments at least every two years, during void periods, and after any significant work on the water system.

Our Role in Minimizing Legionella Risk: We take proactive measures to minimise Legionella risks, including annual boiler services, regular pipework checks, and can even arrange for the flushing of the systems after void periods. Educating tenants on water system reporting, showerhead hygiene, and temperature control further contributes to risk mitigation.
