Aon vs Gallagher: 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.

Gallagher's Executive and Financial Risk practice places fiduciary liability coverage with outside carriers and advises on limits; it does not underwrite the policy. ⁶Company-reported. Group-level executive-and-financial-risk practice page.

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.

The executive-and-financial-risk page does not name the insurer that would issue a given client's fiduciary liability policy. ⁶Not publicly disclosed. Checked the group-level executive-and-financial-risk practice page.

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.

Gallagher targets this coverage at corporations sponsoring retirement or welfare benefit plans, since the described exposure is tied specifically to ERISA fiduciary duties. ⁶Company-reported. Group-level executive-and-financial-risk practice page.

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.

Gallagher describes fiduciary liability as protecting a corporation's Employee Retirement Income Security Act (ERISA) fiduciaries, fiduciary committees and personnel who design or implement 401(k) or pension plans for employees and retirees. ⁶Company-reported. Group-level executive-and-financial-risk practice page; a service description, not a specific policy's insuring agreement or exclusions.

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 page does not publish specific fiduciary liability limits or premium ranges beyond describing its proprietary limit-selection models. ⁶Not publicly disclosed. Checked the group-level executive-and-financial-risk practice page.

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.

Gallagher says it has proprietary models to measure fiduciary risk and assist clients in selecting coverage limits. ⁶Company-reported. Group-level executive-and-financial-risk practice page.
