Legionnaires’ Risk Assessment

What are Legionnaires’ Risk Assessments?

A Legionella risk assessment is a detailed inspection of your water systems to identify anything that could increase the risk of Legionella bacteria growing or spreading.

At Focus On Testing, our assessments are carried out as part of our water hygiene services, and we are proud members of the Legionella Control Association, supporting our commitment to safe, practical and professional Legionella control.

During the assessment, we look at how your water system is designed, used and maintained, including any areas where water may be stored, become stagnant, or sit at temperatures where bacteria can grow.

Key risk areas include:

  • Water temperatures between 20°C and 45°C
  • Stored or re-circulated water
  • Evidence of rust, sludge, scale or organic matter
  • Showers, spray taps or other aerosol-producing outlets
  • Little-used outlets or areas where water can stagnate
  • Poor access for inspection, cleaning or maintenance

A clear report is then provided, outlining any risks found and the practical steps needed to help keep your water systems safe and compliant.

Legionnaires' Risk Assessment FAQs
Do I need a Legionnaires' Risk Assessment?

Yes, if you own or manage a property with a water system, it is highly advisable to have regular Legionnaires' Risk Assessment conducted. This is especially important if your property is a workplace or rented accommodation, as it is a legal requirement for you to take effective control measures against Legionella bacteria.

What are my responsibilities?

As an employer, landlord, or commercial property manager, you must appoint a competent person to help you meet your health and safety duties, and take responsibility for controlling any risk from exposure to Legionella. This is a legal requirement, as Legionnaires’ disease can be fatal - and should not be taken lightly.

What are the symptoms of Legionnaires’ Disease?

The symptoms of Legionnaire’s disease begin similarly to the flu. If you’ve contracted the illness, you’re likely to suffer from:

- High temperature, feverishness and chills
- Cough
- Muscle aches
- Pneumonia
- Diarrhoea
- Signs of mental confusion

Who is most at risk from Legionnaires’ Disease?

Whilst many people will make a full recovery from Legionnaires’ disease, in some cases, it can sadly be fatal. The risk of suffering from Legionnaires’ disease increases with age, but some people are at a higher risk than others. Including the following:

- People over 45 years of age
- Smokers and heavy drinkers
- People suffering from chronic respiratory or kidney disease
- Diabetes, lung and heart disease
- Anyone with an impaired immune system

How often do I need a Legionnaires' Risk Assessment?

The industry standard is every 2 years, but, how long is a piece of string? There is no definitive guideline for how often you should have a Legionnaires' Risk Assessment carried out. This is because some water systems are at much higher risk than others, and individual circumstances will vary. We advise taking a risk-based approach to assessment frequency.

What happens during a Legionnaires' Risk Assessment?

There are three main steps involved during an assessment. The first involves reviewing your records and checking any previous assessments to ensure that all remedial work has been completed. Secondly, we’ll conduct a thorough physical assessment of your water systems and sampling of your water system. After this, we’ll create a detailed report of our findings.
