There’s no fixed timescale for this – but there are six key indicators which will help you decide if your current risk assessment needs to be updated.
Six reasons you may be due for an update
Your Legionella risk assessment must be updated as soon as you believe it’s no longer valid or current. If you have a low risk property where nothing has changed, you may not need to have an update for a number of years. However, if you have a high risk system, it will need to be done more regularly.
When you have your initial risk assessment carried out, you’ll be given a suggested timeframe for an update. But even so, should any of the following six changes occur in the meantime, your risk assessment will need to be updated straight away.
The water system has been changed or is being used differently.
The building use changes.
New information becomes available about the risk or control measures.
Monitoring shows that the control measures set out in your risk assessment are no longer effective.
There’s a change to key personnel such as the duty holder or person identified in the legionella risk assessment.
There has been an outbreak of legionnaires’ disease associated with the system.
