If you manage or own a building, whether it’s a residential complex, office space, hotel, or healthcare facility, protecting your occupants from health hazards is a top priority. One threat that’s often overlooked—but extremely serious—is Legionnaires’ disease.
This potentially deadly respiratory illness is caused by Legionella bacteria, commonly found in building water systems. The good news? It’s preventable with a proper Legionella risk assessment.
What Is Legionnaires’ Disease?
Legionnaires’ disease is a type of pneumonia caused by inhaling small droplets of water contaminated with Legionella bacteria. These bacteria thrive in warm water environments such as:
Hot and cold water systems
Cooling towers
Hot tubs and spas
Air conditioning units
Decorative fountains
While not everyone exposed will become ill, elderly individuals, people with compromised immune systems, and those with chronic lung conditions are particularly vulnerable.
Why Are Legionella Risk Assessments Important?
A Legionnaires’ risk assessment is a legal and proactive way to prevent an outbreak before it happens. It helps you:
Identify and evaluate potential sources of Legionella in your water systems
Implement control measures to minimize risk
Comply with UK regulations such as ACOP L8 and HSG274
Protect staff, tenants, customers, and your business reputation
Failing to carry out an assessment can lead to serious health risks, legal consequences, and financial penalties.
Real-World Impact of Legionnaires’ Outbreaks
Outbreaks of Legionnaires’ disease have occurred in hotels, hospitals, office buildings, and even cruise ships. In addition to the human cost, these incidents often result in massive compensation claims, HSE investigations, and irreparable damage to brand trust.
Who Needs a Legionella Risk Assessment?
If you are:
A landlord or property manager
Responsible for business premises
Operating a care home, school, gym, or hotel
Running a facility with any form of water system
...then you are legally required to assess and manage the risk of Legionella.
