MORE ABOUT Legionella Risk Assessment

What is Legionella Risk Assessment?

A Legionella risk assessment involves evaluating your water systems to identify and control any risk of Legionella bacteria developing. This bacteria thrives in warm water environments, such as those found in cooling towers, hot tubs, air conditioning units and domestic water systems. Without proper control measures, Legionella can spread through water droplets and lead to serious health problems.

Why is Legionella Risk Assessment important for compliance?

Under UK law, particularly the Health and Safety at Work Act 1974 and the Control of Substances Hazardous to Health (COSHH) Regulations, employers have a duty to assess and manage risks from Legionella. Failure to do so can lead to prosecution, hefty fines, and potential prison sentences, not to mention reputational damage.

By conducting a Legionella assessment, you ensure that your business meets the regulatory requirements in the HSE’s ACoP L8. This not only protects your business from legal consequences but also shows that you prioritise the safety and well-being of your staff and visitors

Who needs Legionella Risk Assessment?

Businesses across various sectors are required to conduct Legionella risk assessments. You need a risk assessment if your business:

  • Operates a water system with storage tanks or cooling towers
    This includes industrial sites, hotels, gyms, hospitals, and care homes.
  • Uses hot or cold water systems that are used by the public or employees
    For example, office buildings, schools, leisure centers, and spas.
  • Has air conditioning or refrigeration systems
    Even smaller systems can be a source of contamination if not properly maintained.


If you’re unsure whether your business needs a Legionella risk assessment,
Office Test can guide you through the requirements and assess your current situation.

How often should Legionella Risk Assessment be done?

The frequency depends on the type of water systems in use and the level of risk involved. As a general rule, it’s recommended that assessments be done:

  • The frequency depends on your water systems and risk level — there’s no fixed legal interval, but you should review the assessment regularly and update it whenever circumstances change or the previous findings are no longer valid.
  • When there are significant changes
    If your business expands, your water systems are modified, or you introduce new equipment, a new risk assessment may be required.
  • Following any Legionella outbreak or increased risk discovery
    Immediate reassessment is crucial to ensure no further health risks.
