Aon vs Kinro: Professional Liability / E&O Insurance

What Are the Key Differences Between Aon and Kinro Professional Liability (E&O) Insurance?

Professional Class and Product Scope

Aon describes professional liability as a structure tailored to professional-services firms’ needs and names law, accounting and consulting as its practice audience. Kinro says E&O fit depends on the operation and carrier appetite; to quote, it gathers the services performed, client types, revenue, contract terms, prior claims and retroactive dates. That intake gives buyers a clear list of materials to prepare and makes the carrier-matching role explicit. [1] [4]

Placement Detail and Buyer Decisions

Kinro often reviews E&O alongside cyber, general liability and D&O, while Aon’s overview describes professional-services advisory support without naming a specific placement workflow. Kinro’s page does not publish limits, retentions or premiums; Aon also leaves account terms open. Both routes require a quote to establish coverage. Ask how each broker will treat regulated or technical advice and whether the retroactive date preserves prior work. [1] [4]

Ask Kinro which markets will consider your services and what retroactive date and limits are available. [1] [4]
Ask Aon for the application details, carrier and how it coordinates E&O with cyber and D&O. [1] [4]

eligibility: Kinro says this coverage commonly fits consultants, agencies, tech services and professional firms, and typically comes up when clients rely on the business's professional advice or deliverables, or a contract requires E&O or professional liability.
