Aon is a global professional services firm providing insurance and reinsurance brokerage, risk management, retirement, and health consulting services to businesses and organizations.
Aon is a global professional services and insurance brokerage firm headquartered in Dublin, Ireland, with operations in more than 120 countries. The company works primarily with businesses, universities, associations, and other organizations to design and place insurance coverage, manage risk, administer employee benefits, and provide retirement and health consulting. In addition to large corporate accounts, Aon or its subsidiaries may also administer individual policies and programs such as travel insurance, student insurance, professional liability coverage, membership or association insurance plans, and employer-sponsored benefit plans.
A charge from Aon may appear on your bank or card statement when you purchase or renew an insurance policy or enroll in a benefit program administered by Aon or an Aon affiliate. Common scenarios include monthly or annual insurance premiums (for travel, tuition, student health, professional liability, or association-related coverage), payroll-replacement if your employer uses a card-on-file instead of payroll deduction, or self-pay premiums for COBRA or retiree health benefits. You may also see temporary authorization holds when you first set up a payment method, make a change to coverage, or request a quote and choose to bind coverage online—these small or duplicate-looking amounts usually fall off within a few business days. Some Aon programs renew automatically each term unless you cancel, which can result in recurring charges you may not immediately recognize.
To verify an Aon charge, start by reviewing recent insurance enrollments, benefit elections through your employer, university, or professional association, and any travel or event insurance you may have purchased. Check your email for a policy confirmation or certificate from Aon, Aon Affinity, or an Aon-branded program, and compare the billed amount and date to that documentation. If you still have questions, visit aon.com and use the Contact or Support section to locate the specific program or country office associated with your policy, or refer to the customer service phone number or email printed on your policy documents. Having your policy number, employer or school name, and the exact charge details (date, amount, and the billing descriptor shown on your statement) will help Aon support quickly locate your account, explain the charge, adjust coverage, or assist with cancellations and refunds where eligible.

Why am I seeing a charge from Aon on my bank or credit card statement?
Most consumer-facing Aon charges relate to insurance premiums or benefit programs that Aon administers on behalf of employers, universities, associations, or travel providers. Common examples include travel insurance, student or tuition insurance, professional liability coverage, association membership insurance, COBRA or retiree health premiums, or voluntary benefits you elected during enrollment. Review recent enrollments, travel bookings, and benefit elections, as well as emails from Aon or your employer/school, to match the charge to a specific policy or program.
What are typical charge amounts from Aon, and how often will I be billed?
Aon does not have a single standard price, as premiums vary by program, coverage level, age, and location. You may see one-time charges (such as for a single-trip travel policy or a semester-based student insurance plan) or recurring monthly/annual premiums for ongoing coverage like voluntary life, accident, or professional liability insurance. The frequency—monthly, quarterly, per semester, or annually—will be stated in your policy documents or enrollment confirmation. If the amount on your statement differs from what you expected, contact the program-specific Aon support team listed on your policy certificate.
How do I cancel or stop recurring Aon insurance or benefit charges?
Cancellation must be done through the specific Aon program or the organization that sponsored your coverage. In many cases, you can cancel by logging into the online portal linked in your Aon enrollment confirmation email, or by contacting the customer service number shown on your policy or benefits materials. For employer or university plans, you may need to change your elections through your HR or student benefits portal, which then updates Aon’s billing. Be sure to ask whether cancellation is effective immediately or at the end of the current coverage period, and whether any minimum term or non-refundable period applies.
How can I request a refund for an Aon charge I don’t recognize or no longer want?
Refund eligibility depends on the specific policy type and terms disclosed at purchase. Some Aon programs offer a short “free look” period (for example, 10–30 days) during which you can cancel for a full refund if no claims have been filed, while others may permit only partial or no refunds after coverage starts. To request a refund, contact the customer service team listed on your certificate of insurance or confirmation email, provide your policy number and transaction details, and explain why you are disputing the charge. If you cannot locate your documents, you can start at aon.com, select your country and product area (e.g., travel, student, professional liability), and use the contact form or phone number provided.
Why do I see a small or duplicate pending charge from Aon on my account?
Small or duplicate-looking charges from Aon are often temporary authorization holds placed by your bank to verify your card when you enroll in a program, update payment details, or modify coverage. These authorizations may appear as $0, $1, or a small test amount, and should automatically drop off or be reversed within a few business days, never posting as finalized charges. If a pending hold remains for more than 7 business days or posts as a completed transaction you did not authorize, contact both your card issuer and the appropriate Aon support team with a screenshot of the transaction details.
How can I contact Aon about a specific charge or policy on my account?
The fastest way to get help is to use the contact information shown on your policy documents, enrollment confirmation email, or benefits materials, as each Aon program is serviced by a dedicated team. If you don’t have those documents, go to aon.com, select your country, then navigate to the relevant section (such as Health & Benefits, Retirement, or Affinity/Travel/Student Insurance) to find program-specific phone numbers and email addresses. Have ready your full name, sponsoring organization (employer, school, or association), the last four digits of the card charged, the exact amount, date, and any billing descriptor (e.g., “AON INSURANCE,” “AON BENEFITS,” or similar) from your statement.
I thought my premiums would come out of payroll, so why did Aon charge my card directly?
In some situations—such as COBRA or retiree health coverage, leave-of-absence benefits, or certain voluntary plans—your employer or plan sponsor may require you to pay premiums directly rather than through payroll deduction. When this happens, Aon or an Aon affiliate may collect premiums by debit/credit card or bank draft, resulting in a visible charge on your statement instead of a line on your pay stub. Check any letters or emails you received about changes to your employment status or benefits, as they often explain that Aon will handle direct billing, and contact the number listed in those communications if you need to switch payment methods or adjust coverage.
How can I confirm which Aon program my charge belongs to if I have multiple policies?
Start by comparing the exact charge amount and date with your recent policy schedules or renewal notices from Aon, Aon Affinity, or any Aon-branded program you use (travel, student, professional, or association plans). Look at the billing descriptor on your statement—often it includes a clue such as “TRAVEL,” a university name, an association acronym, or a country indicator that narrows down the program. If you still can’t match it, contact Aon with your name, email address used at enrollment, sponsoring organization, and the transaction details; support can search across programs to locate the correct policy and explain the charge.
