Frequently Asked Questions About Legionella Risk Assessment & Water Safety
What is Legionella and why is it dangerous?
Legionella is a type of bacteria found in water systems that can cause Legionnaires’ disease – a potentially fatal form of pneumonia. It poses particular risk in man-made water systems like cooling towers, hot and cold water tanks, and spa pools.
Who needs a Legionella risk assessment?
Any person or business responsible for a building where water is stored or circulated – such as landlords, employers, and property managers – has a legal duty under UK law (e.g., Health and Safety at Work Act 1974 and ACOP L8) to assess and control the risk of Legionella.
Is a Legionella risk assessment a legal requirement?
Yes. UK regulations (including HSE’s ACOP L8 and HSG274) require duty holders to carry out a Legionella risk assessment and take appropriate precautions to prevent exposure.
How often do I need to carry out a Legionella risk assessment?
Typically, risk assessments should be reviewed at least every two years, or sooner if there are changes to the water system, building use, or management responsibilities. Annual reviews are recommended in high-risk environments.
What does a Legionella risk assessment involve?
A legionella risk assessment involves inspecting water systems, identify potential sources of risk, assessing current control measures in place, and providing a detailed report with any recommended actions. This includes temperature checks, schematic diagrams, and maintenance advice.
Do I need a Legionella assessment for a residential property?
If you are a landlord, yes – you have a duty of care to ensure your tenants are not at risk from Legionella. A simple risk assessment may suffice for most residential properties, especially if water systems are low-risk.
How long does a Legionella risk assessment take?
For an average-sized building, it usually takes 2 – 6 hours. Larger or more complex buildings may take longer. You will receive the report via email upon completion of the typed report.
