Aon vs HUB International: How Do They Compare for Fiduciary Liability Insurance?

Aon presents Fiduciary Liability as a line its Professional Services Practice helps arrange or advise on for professional-service firms. Aon is describing a global brokerage and advisory service, not issuing the underlying policy. The producing legal entity and carrier for any particular placement are not named on this page. ³Company-reported. Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement.

HUB brokers fiduciary liability insurance for employers that sponsor health-care and retirement benefit plans, rather than underwriting the coverage itself. ⁷Company-reported. Fiduciary liability product page, read 2026-09-23. The page does not name an issuing insurer.

The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. ³Not found in reviewed sources. Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement.

No insurer is named for fiduciary liability on the product page; the carrier depends on the placement. ⁷Not found in reviewed sources. Checked the fiduciary liability product page on 2026-09-23.

Aon identifies law, accounting and consulting firms as the audience for its global Professional Services Practice. That audience scope does not establish eligibility for every firm or other business. ³Company-reported. Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement.

HUB targets fiduciary liability brokerage at employers offering health-care or retirement benefit plans who face potential litigation from plan participants, the Department of Labor or the Pension Benefit Guaranty Corporation. ⁷Company-reported. Product-page target-audience description; not a published underwriting appetite.

Aon lists Fiduciary coverage within the professional-services practice’s property-and-casualty coverages. The page does not describe covered fiduciary acts, plans, exclusions or policy terms. ³Company-reported. Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage.

HUB lists fiduciary liability claim scenarios it covers as including a plan's insurer, mutual fund or third-party administrator making bad choices, plan administration errors or conflicts of interest, benefits denial, changes or reductions, bad advice or improper counsel, insufficient plan funding, poor investment selection and incorrect plan termination. ⁷Company-reported. Product-page list of covered claim scenarios; the issued policy's insuring agreement and exclusions control an actual claim.

HUB states that fiduciary liability exposure "is not covered by director's and officers' liability policies," positioning fiduciary liability as a separate line from D&O rather than a bundled coverage. ⁷Company-reported. Product-page statement distinguishing fiduciary liability from D&O.

The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. ³Not publicly disclosed. Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed.

The product page does not publish specific policy limits or retentions; it references that combined defense and settlement costs on fiduciary claims can exceed $1 million as a risk statistic, not a policy limit. ⁷Not publicly disclosed. Checked the fiduciary liability product page on 2026-09-23; the $1 million figure describes potential exposure, not an offered limit.

Aon says its professional-services advisors use industry knowledge, insights, data and tools to support risk-management and human-capital decisions. This is a company-described advisory service, not a claim outcome or policy benefit. ³Company-reported. Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated.

HUB publishes a video on preventing fiduciary liability claims and administrative-error best practices on the product page, but the page does not describe a formal fiduciary risk-management or plan-review service. ⁷Company-reported. Product-page educational video reference.

HUB directs fiduciary liability prospects to "Connect With a Broker" or "Contact a HUB broker" rather than an online quote or bind flow. ⁷Company-reported. Product-page calls to action.
