Frequently Asked Questions (FAQs) about PI insurance for the industry: 

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 PI insurance for accountants 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 claim?
