Aon Reviews and Ratings
The sources reviewed do not provide one comparable measure of Aon’s U.S. commercial brokerage service. Trustpilot’s global aon.com profile showed 1.2/5 from 782 reviews, while J.D. Power’s 2017 large-commercial study ranked Aon third at 822/1000. BBB separately showed a B− business grade tied to two unanswered complaints and 1.6/5 from five customer reviews. These sources have different populations, dates and measures; none is a current commercial-placement outcome study.[4][2][6][7]
Review sources describe different Aon entities and services; none isolates outcomes for U.S. commercial insurance placements.

This is historical and should not be presented as a current score.[2] Source detailsHistorical 2017 large-commercial-broker study; U.S. and Canada commercial insurance decision-makers at large organizations.

| Trustpilot | 1.2/5TrustScore 782 reviews | The profile showed 1.2/5 from 782 reviews, including 198 in the preceding 12 months. Trustpilot says the profile has no recent history of asking for reviews and reviews may not be representative; its profile is merged and replies to 4% of negative reviews. Visible reviews include a professional-indemnity claim-delay allegation and an Australian business quotation-service allegation; Aon’s response to the latter acknowledged the reported delays and communication. These individual accounts are unverified and do not establish U.S. commercial-placement outcomes or insurer fault.[4] Source detailsGlobal www.aon.com profile merged with other Aon profiles; mixed experiences include pensions, travel, professional indemnity and Australian business quotation service. The two latter complaints are individual unverified allegations, not evidence of U.S. commercial-placement outcomes or insurer fault.

| BBB | B−BBB business grade | The profile showed a B− BBB business grade and stated reason: failure to respond to two complaints filed against the business.

- NerdWallet
No Aon broker rating was located on the reviewed page. NerdWallet says it does not rate online brokers that do not underwrite policies.[1]
NerdWallet small-business insurance recommendation page reviewed 2026-09-29; its stated review framework excludes online brokers that do not underwrite. This is one editorial page, not an exhaustive directory or proof that NerdWallet never discusses Aon.
- NAIC
No Aon broker-level rating or complaint index was located on the reviewed NAIC consumer page. This does not mean an agent complaint does not exist; the exact producing entity and state were not searched.[3]
NAIC consumer complaint guidance reviewed; the page refers problems with an insurance company or agent to the relevant state department. No state complaint search was completed for Aon or a placement-specific producer.
- ConsumerAffairs
No exact Aon commercial-broker review profile was located in the reviewed ConsumerAffairs search. Related Aon/Aon-affinity travel-policy references are not treated as evidence about Aon’s U.S. commercial brokerage. This is a bounded search outcome, not proof of absence.[5]
ConsumerAffairs insurance index and site-restricted searches for Aon insurance reviews, checked 2026-09-29. Search did not surface an exact Aon U.S. commercial-broker profile; no complete directory export or exhaustive archive search was done.
Different Measures and Dates
Trustpilot’s global www.aon.com profile showed 1.2/5 from 782 reviews, including 198 in the preceding 12 months, when checked on September 29, 2026. Trustpilot says the profile has no recent history of asking for reviews and reviews may not be representative; the profile is merged and includes pension and travel-insurance experiences. Visible reviews also include professional-indemnity claim-delay and Australian quotation-service allegations. These individual accounts are unverified and do not establish outcomes for U.S. commercial placements; Aon’s response to the Australian quotation review acknowledged the reported delays and communication. It does not isolate U.S. commercial placements.[4]
J.D. Power’s 2017 Large Commercial Insurance Study ranked Aon third among large commercial brokers with a score of 822/1000. The study is historical. Its study-wide evaluation count is not an Aon-specific customer-review count, and the release does not supply an Aon response count.[2]
BBB Grade and Customer Reviews
BBB’s Chicago & Northern Illinois business profile is for Aon plc and displays a B− letter grade. BBB gives the reason as failure to respond to two complaints filed against the business. The profile describes the business as handling reinsurance for AON Corp; this is not a commercial-broker performance score or an insurer financial-strength rating.[6]
A separate BBB customer-review page shows an average of 1.6 from five reviews. Keep that customer rating separate from the B− business grade. The visible review material includes employee-benefit and medical-expense contexts and does not establish a U.S. commercial insurance placement sample.[7]
What These Sources Do Not Show
The reviewed NerdWallet business-insurance page says it does not rate online brokers that do not underwrite policies; no Aon broker rating was located on that page. The NAIC consumer page directs people with an issue involving an insurance company or agent to the relevant state department, but no placement-specific agent or state search was completed. ConsumerAffairs site searches did not surface an exact Aon U.S. commercial-broker review profile; that bounded search is not proof no profile exists.[1][3][5]
Limitations
- The Trustpilot profile is global, merged and spans multiple products and services; Trustpilot itself says the sample may not be representative.
- The J.D. Power result dates to 2017 and concerns large commercial brokers; it is not a current score or a customer-review average.
- BBB’s company grade, stated complaint-response reason and separate customer-review average are distinct measures. The profile’s listed entity and business description do not establish placement-specific commercial brokerage outcomes.
- No reviewed platform supplies a comparable, current sample isolated to Aon’s U.S. commercial insurance placements. Do not pool platform measures into a consumer average.
Questions to Ask
- Which Aon legal entity will produce the proposed policy, and what insurer will issue it?
- What compensation will Aon receive for this placement, including any contingent or other compensation?
- Who must notify the insurer of a claim, and what claims advocacy or preparation services are included in the engagement?
