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.

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.
