What is Legionnaires’ Disease?

Legionnaires’ disease is a potentially serious form of pneumonia caused by inhaling small droplets of water contaminated with Legionella bacteria. These bacteria can develop in man-made water systems such as hot and cold water systems, tanks, showers, and pipework. (HSE)

The risk increases when water:

Is stored or recirculated
Sits between 20°C and 45°C
Contains nutrients like sludge or rust
Produces airborne droplets (e.g. showers or taps) (HSE)

Do You Need a Legionella Risk Assessment?

Under UK law, landlords, employers, and anyone responsible for a property must assess and control the risk of Legionella. This duty falls under:

Health and Safety at Work etc. Act (HSWA)
Management of Health and Safety at Work Regulations
Control of Substances Hazardous to Health Regulations (COSHH) (HSE)

If you own or manage property in Norwich or Norfolk, you are legally required to:

Identify potential sources of Legionella
Assess the level of risk
Implement control measures
Maintain records and review regularly (HSE)

For landlords, even simple domestic properties require a risk assessment, although in many cases the risk is considered low and easy to manage. (HSE)

What Does a Legionella Risk Assessment Involve?

A Legionella Risk Assessment is a detailed inspection of your property’s water systems. It includes:

Identification of water systems (tanks, cylinders, pipework, outlets)
Checking water temperatures and storage conditions
Identifying risk factors such as stagnant water or unused outlets
Assessing the likelihood of aerosol exposure
Reviewing current control measures
Providing a written report with recommendations

The goal is to determine whether conditions exist that allow bacteria to grow and spread, and to create a clear plan to manage that risk. (Occupational Health and Safety Blog)

Common Risk Areas in Properties

In homes and rental properties across Norwich and Norfolk, typical risk areas include:

Hot and cold water systems
Showerheads and taps
Water storage tanks
Dead-leg pipework (unused sections)
Properties left vacant for long periods

Any system that allows water to stagnate or sit at the right temperature can create conditions for Legionella growth. (HSE)

Control Measures & Prevention

Most domestic properties are considered low risk, but simple control measures are still essential:

Keep hot water stored at 60°C and distributed at safe temperatures
Ensure cold water is kept below 20°C
Regularly flush unused outlets
Clean and descale showerheads
Remove redundant pipework
Avoid water stagnation, especially in vacant properties (HSE)

These practical steps significantly reduce the likelihood of bacterial growth.

How Often Should a Legionella Risk Assessment Be Done?

There is no strict legal requirement for annual assessments, but they should be reviewed regularly and updated when:

There are changes to the water system
The property layout is altered
The occupancy changes
Control measures are no longer effective

Regular reviews ensure ongoing compliance and safety.
