Key Differences in Employment Practices Liability Insurance

Placement and Buyer Fit

WTW’s corporate risk terms describe its role as an insurance intermediary, and its annual report lists employment-practices liability among FINEX solutions. Aon likewise describes arranging or advising on EPL for professional-services firms. The available WTW evidence confirms line placement within a broader practice rather than product terms; buyers should identify the specific engagement terms and service team before comparing policy recommendations. 3 9

Published Coverage and Service Detail

WTW’s terms say a quote is not confirmation of coverage: when asked to bind, WTW seeks an insurer commitment, usually a binder, and reviews binders, policies, and endorsements against negotiated terms. Aon’s offering page does not describe those document checks. These steps affect placement administration, not coverage itself, so ask both brokers who verifies the issued wording against the agreed quote. 3 9

What to Confirm in Employment Practices Liability Insurance Quotes

  • Ask WTW which engagement terms govern your account and how policy discrepancies are escalated. Ask Aon whether its service includes binder and endorsement review; request carrier and final wording from both. 3 9

Aon vs WTW: Employment Practices Liability Insurance: documented features by provider

CriteriaAon Employment Practices Liability brokerage and risk-advisory offeringWTW Employment Practices Liability Brokerage
Role in This Line

Aon presents Employment Practices 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.

Under WTW's North American Corporate Risk & Broking terms, WTW normally acts as the client's insurance intermediary for engagements governed by those terms. 9Company-reported. Terms for applicable North American Corporate Risk & Broking engagements. WTW also discloses separate insurer-side services in some arrangements; this does not determine the role in a specific engagement.

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.

The reviewed WTW sources do not identify an issuing insurer for a specific employment practices placement. 9,8Not publicly disclosed. This is a gap in the cited marketing, annual-report, and brokerage materials; it does not mean WTW lacks insurer markets. Confirm the carrier on the quote and issued policy.

Who It’s For

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.

Confirm in your quote.

Coverage Features

Aon describes EPL as addressing specialized liability risks arising from actual or alleged workplace wrongdoing and says it provides customized coverage solutions for professional-services firms. This does not establish any specific policy grant. 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.

WTW's FY2024 annual report lists employment-practices liability insurance among its FINEX solutions. 8Company-reported. Historical group-level service description only; current U.S. placement, insurer, policy wording, and buyer eligibility are not established.

Limits and Retentions

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 reviewed sources do not state a buyer-specific employment practices limit, retention, or deductible. 9,8Not publicly disclosed. No limit or deductible is inferred from general marketing or WTW's brokerage role; the insurer's quote and issued forms control.

Risk Services

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.

WTW's North American terms describe reviewing binders, policies, and endorsements against the terms negotiated with the insurer. 9Company-reported. Broker document-review process under the cited terms, when WTW handles this line's placement. It does not certify that a policy covers a claim or replace the issued wording.

How to Apply

Confirm in your quote.
