Aon Reviews 2026
Public ratings for Aon are low: Trustpilot shows 1.2 out of 5 from 782 reviews, and BBB shows 1.6 from five. Aon is a global firm, so those pages mostly reflect other parts of the business, not large U.S. commercial accounts.[4][6][7]

| Trustpilot | 2.4/ 10 Original: 1.2 / 5 782 reviews Excluded from Review Score: The merged global profile mixes pensions, travel, professional indemnity and an Australian quotation service with other Aon businesses; it does not measure a comparable commercial-brokerage population. | 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.

- 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.
Trustpilot shows 1.2 from 782 reviews
The Aon page on Trustpilot has 782 reviews, 198 of them in the past year. It mixes pensions, travel, professional indemnity and an Australian business quoting service, so it isn't a clean picture of Aon as a commercial broker.[4]
Trustpilot says Aon hasn't recently invited reviews, so the page may not be representative. Aon replies to about 4% of the negative ones.[4]
BBB gives Aon a B-
The Better Business Bureau of Chicago lists Aon with a B- grade. It gives failing to respond to two complaints as the reason. That grade reflects how the business handles BBB complaints, not customer stars, though it counts toward the Review Score.[6]
A separate BBB page shows 1.6 out of 5 from five customer reviews, some about employee benefits and medical expenses. It counts toward the Review Score.[7]
A 2017 study ranked Aon third
J.D. Power's 2017 study of large commercial brokers scored Aon 822 out of 1,000, third place. It surveyed decision-makers at large organizations in the U.S. and Canada.[2]
That study is nine years old and covers big companies, so don't read it as a current score for a small business.[2]
What Did Spot Not Find for Aon?
NerdWallet doesn't rate Aon, and says it doesn't rate online brokers that don't underwrite. ConsumerAffairs shows no page for Aon's commercial brokerage, and the NAIC consumer page shows no complaint record for it.[1][5][3]
What Counts Toward the Aon Review Score?
Aon's Review Score is 6.1 out of 10. It averages the 2017 J.D. Power score of 822 out of 1,000 (about 8.2), the BBB B- grade (about 6.8) and the BBB customer review average of 1.6 out of 5 (3.2). The Trustpilot page is left out because it mixes many unrelated services.[4][6][7][2]
Limitations of Aon Review Data
- Trustpilot mixes several Aon businesses in several countries.
- BBB's average rests on only five reviews.
- The J.D. Power result is from 2017 and covers large organizations.
- We found no complaint record for the specific Aon entity that would serve you.
