When does it need to be repeated?

The fire risk assessment process is intended to be a continuous process, and take into account change.

Fire risk assessments should therefore be reviewed periodically which is generally accepted in the industry as at least annually,or if there is a reason to suspect that it is no longer valid, and, in particular, if significant changes take place, such as an increase in the numbers of people in the building or changes to floor layouts.

Fire risk assessments should also be reviewed after a fire.

I will give a suggested date for review in our reports. A review does not necessarily involve repeating the fire risk assessment process. A judgement on this is required based on the significance of the changes but it should be revised within 3 years.
