Understanding and Reducing the Risk of Legionella in Your Property

Legionella bacteria, responsible for the potentially fatal respiratory condition known as Legionnaires' disease, pose a silent but significant health threat in residential properties. With an estimated 200-250 confirmed cases each year in England and Wales, and possibly many more undiagnosed, understanding and mitigating the risks associated with this bacteria is crucial for property owners, especially residential landlords.

What is a Legionella Risk Assessment (LRA)?

A Legionella Risk Assessment (LRA) is a critical evaluation designed to identify the potential presence of Legionella bacteria in a property. Given that 10% of those infected with Legionnaires' disease may succumb to it, conducting an LRA is not just a safety measure—it's a vital action that could potentially save lives. This assessment checks environments where Legionella could thrive, particularly in water systems that are ideal breeding grounds for these harmful bacteria.

Common Sources of Legionella in Residential Properties

Legionella bacteria typically thrive in water systems that are not frequently used or poorly maintained. In residential settings, the most common sources include:

  1. Showers and Taps: Where stagnant water can provide a perfect environment for Legionella if not regularly used and flushed.

  2. Hot Tubs: Especially those that are not regularly drained or adequately disinfected.

  3. Decorative Fountains and Water Features: Where water is kept at temperatures conducive to bacterial growth.

  4. Hot Water Tanks and Heaters: If not maintained at the correct temperatures.

  5. Large Plumbing Systems: Especially in older buildings where water stagnation is more likely.

Why Residential Landlords Need an LRA

Landlords have a legal responsibility to ensure the safety of their tenants. This includes assessing and controlling the risk of Legionella as mandated by the L8 Approved Code of Practice (ACOP) issued by the Health and Safety Executive in 2001. Compliance not only helps prevent the occurrence of Legionnaires’ disease but also ensures that landlords meet their legal obligations, protecting them from potential liabilities.
