Legionella Risk Assessment

Legionella is a group of bacteria that easily colonise and live in domestic, commercial, and industrial water systems. It could be hiding in yours and result in an outbreak of Legionnaires’ disease, a form of pneumonia which can have a high mortality rate. Legionella risk exists in all types of water systems, properties, and premises.

What is a Legionella Risk Assessment?

A legionella risk assessment is a process used to assess, remediate, and monitor the risks of Legionnaires disease within a premises. It looks at the water system as a whole, the way in which the building is used, and what the most appropriate control measures may be.
Once your Legionella Risk Assessment has been completed and any sampling required has take place, we will provide you with a written scheme of controls to help you manage your risk.

An essential part of managing risk and putting effective control measures in place is having a record-keeping system. We will also provide log books to help support you in this.

If your assessment suggests action is needed we can provide additional sampling, remedial works and awareness training at a range of premises throughout the UK.

Is it a legal requirement to have a Legionella Risk Assessment?

Yes, Legionella is seen as a biological agent and requires management under the Health & Safety at Work Act 1974 and COSHH Regulations 2002. Duty holders, including landlords, business owners, employers and property managers, are legally obliged to manage any risk from Legionella. As a general rule of thumb, if you have water on site – you have a potential for Legionella.

What systems are checked as part of the Legionella Risk Assessment?

Risk Assessments will cover all areas of your water system, from cold water storage tanks, little used outlets such as taps and showers, but also some of the water sources that might otherwise get forgotten:

  • Water butts
  • Pools
  • Hose reels
  • Fountains
  • Uninspected water tanks
  • Unused shower heads
  • Emergency showers
  • Jet washers
  • Vehicle wash systems.
