Legionella Risk Assessments

Legionella is the bacteria responsible for legionnaires disease, an uncommon but potentially fatal lung infection. Legionnaires disease is contracted through exposure to and inhalation of tiny water droplets and vapour from water systems containing high levels of the legionella bacteria. The bacteria thrives in warm and hot water, however, in warmer climates, even cold water systems may reach temperatures sufficient for legionella to grow.

Who Needs Legionella Risk Assessments?​

Business owners, employers, landlords and persons in control of premises are responsible for managing the risk of legionella within water systems and water storage tanks. According to the Health & Safety Executive (HSE), the aforementioned individuals must:

  • Identify and assess sources of risk
  • Manage any risks
  • Prevent or control any risks
  • Keep and maintain the correct records
  • Carry out any other duties required.

All water systems should be monitored for legionella bacteria, however, particular attention should be paid to:

  • Hot and cold water systems  
  • Air conditioning systems and evaporative condensers 
  • Hot tubs, jacuzzis and spa pools 
  • Showers 
  • Fountains 
  • Sprinklers and car wash stations.

At ARA Environmental, our comprehensive legionella risk assessments include:

  • A thorough and careful inspection of the site 
  • Water temperatures analysis from various locations within the premises 
  • Review of all site assets eg. water systems, pipework and identification of risks 
  • Review of pipework configurations and water sources and identification of risks 
  • Detailed scheme of legionella control actions 
  • WRAS compliance check 
  • Site assets and associated risks are photographed

A Legionella risk assessment is only the first step in preventing legionnaires disease and achieving full ACoP L8 compliance. In addition to the initial assessment, further action is required to achieve compliance. Full AcoP L8 compliance is achieved through provision of additional water hygiene services.  

As members of the LCA, ARA Environmental offers a comprehensive package of measures designed to ensure the duties of the ‘responsible persons’ are fulfilled, and any risk of a legionnaires disease outbreak is managed through the appropriate legionella control measures.

How Often Do I Need A Legionella Risk Assessment?

According to new ACoP L8 regulations, a legionnaire’s testing certificate must be a ‘live document’ which is regularly reviewed, updated and maintained. At minimum, a legionella risk assessment should be reviewed every 2 years. It should also be reviewed any time there is a significant change made to your water systems.

Legionella Risk Assessments for Landlords and Letting Agents

Health and safety legislation does not require landlords to perform legionella water quality analysis at residential properties, however, it is a legal requirement that the landlord or letting agent in charge of the domestic property ensure any risk of exposure to legionella is properly mitigated and managed.

Under UK law, landlords and letting agents of single dwellings are permitted to carry out legionella risk assessments themselves, as long as they have the appropriate training and required knowledge to do so.

Legionella training is an essential and mandatory component of any legionella risk management programme. Here at ARA Environmental, we offer bespoke water hygiene training packages to business, landlords, individuals and ‘responsible persons’.

Our legionella risk course provides our customers detailed information on the subject of legionella, the control of legionella bacteria and its causes, including current and up-to-date legislative requirements. Delegates will:

  • Develop a knowledge of how to meet the risk assessment requirements of the Fourth Edition Approved Code of Practice (ACoP L8) and associated Technical Guidance Document HSG 274 Part 2.
  • Study BS 8580-1:2019 Water Quality – Risk Assessments for Legionella Control – Code of Practice.
  • Understand the procedure to follow throughout the risk assessment.
  • Learn how to create and develop risk assessment templates

In order to remain compliant with legislation, we recommend that legionella risk training is renewed every two years.
