How long has it been since your last Legionella Risk Assessment?

May 2021

Are you confident that your Legionella Risk Assessment is up to date?

It maybe some time since your last Legionella Risk Assessment. Are you unsure how often this needs to be updated?


The Health & Safety Executive L8 Approved Code of Practice states that a Legionella Risk Assessment should be a living document that must be reviewed to ensure it stays up to date.

The assessment should be reviewed regularly (at least every two years) and specifically if it is suspected to be no longer valid. An indication of when to review the assessment and what to consider should be recorded. This may result from, eg:

(a) changes to the water system or its use;

(b) changes to the use of the building in which the water system is installed;

(c) the availability of new information about risks or control measures;

(d) the results of checks indicating that control measures are no longer effective;

(e) changes to key personnel;

(f) a case of legionnaires’ disease/legionellosis associated with the system.

In addition the HSG274 Part 2 outlines: “It is a legal duty to carry out an assessment to identify and assess whether there is a risk posed by exposure to legionella from the hot and cold water system or any work associated with it.”
