There are two types of Professional indemnity insurance policies sold.
"Any One Claim" and "Aggregated" these are defined as:
If the limit is ‘any one claim’ this means that the most that the insurer will pay out per claim is the limit specified. You could have several claims in the same policy period and whilst each would be subject to the specified limit there would be no overall limit.
If the policy is on an ‘aggregate’ basis then the limit is the maximum that will paid out in the policy period irrespective of the number of claims you may have.
Limits of professional indemnity insurance differ according to each and every trade, and sometimes the difference between the lowest levels is not that much.
