What is Professional Indemnity insurance?

Professional Indemnity insurance provides cover should a third party suffer a financial loss as a result of your professional error, omission or negligence. 

What limit of indemnity do I need?

We recommend you check your institute’s guidelines. It is always good practice to review your contracts both pending and current to assess whether your limit of indemnity is sufficient. 

Will my policy cover my past work?

The policies we arrange provide cover retrospectively. 

Would my policy respond if I have a claim for work I undertook 3 years ago before I moved to Aon?

Professional Indemnity is constructed on a claim made basis and it is the policy in force when the claim is made, which would respond regardless of when the work was undertaken, subject to policy terms and conditions.

How do I make a claim?

In the event of a claim, notify Aon Claims Solutions (ACS) as soon as possible. Any notifications must be made to:
