What Is Errors & Omissions (Professional Liability) (E&O)?
Errors & Omissions (E&O), also called Professional Liability, covers claims that your professional advice, design, or service caused a client financial loss. It is essential for consultants, engineers, brokers, and other advice-based businesses.
Where CGL responds to physical injury or property damage, E&O responds to economic loss from your professional work — a missed deadline, a flawed design, or a recommendation that did not perform. Many contracts and professional bodies require it.
