Harper vs WTW: How Do They Compare for Professional Liability (E&O) Insurance?

Harper places professional liability coverage as a broker, writing the policy around the applicant's actual services rather than underwriting it, and describes a specialist handling the placement. ³Company-reported. Professional liability page introduction and 'Why Harper' section.

Harper markets the identical policy under two catalogue entries, "Professional Liability" and "Errors and Omissions"; the E&O page states it is the same policy, just named what a given industry calls it. ^4,5Company-reported. Coverage directory listing plus the E&O page's own description; a naming convention Harper states about itself, not a distinction between two products.

Under WTW's North American Corporate Risk & Broking terms, WTW normally acts as the client's insurance intermediary for engagements governed by those terms. ¹¹Company-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.

The reviewed pages name pricing drivers (services performed, revenue, contract size) but do not name the issuing insurer or publish specific limit, retention or premium figures for this line. ^3,4Not publicly disclosed. Checked both the professional-liability and errors-and-omissions pages on 2026-09-23; neither names a carrier or a limit figure.

The reviewed WTW sources do not identify an issuing insurer for a specific professional errors omissions placement. ^11,10,9Not 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.

Harper targets consultants, agencies, tech firms and licensed professionals whose work product is advice, design or a decision, since general liability doesn't cover a client claiming that work caused a financial loss. ³Company-reported. Professional liability page introduction and FAQ distinguishing it from general liability.

Confirm in your quote.

Harper describes coverage for errors and omissions in the work itself, negligence allegations about professional judgment, and legal defense costs, with limits it says are matched to the client contracts that require the policy. ^3,4Company-reported. Professional liability page's four coverage tiles; the E&O page adds that claims often surface a year or more after the work was delivered. The issued policy and its exclusions control actual scope.

WTW's FY2024 annual report describes professional-liability solutions within FINEX; its residential practice lists errors-and-omissions among financial lines for residential real-estate stakeholders. ^10,9Company-reported. The report is historical and group-level; the residential E&O reference is segment-specific and based on retained official indexed text. Neither establishes current terms or eligibility outside that segment.

Confirm in your quote.

The reviewed sources do not state a buyer-specific professional errors omissions limit, retention, or deductible. ^11,10,9Not publicly disclosed. No limit or deductible is inferred from general marketing or WTW's brokerage role; the insurer's quote and issued forms control.

Harper says it reads a policy's exclusions line by line before a client buys, because two E&O policies with the same limit can respond very differently to the same claim. ³Company-reported. Professional liability page 'We know this' section; a described review practice, not an independently verified outcome.

WTW's North American terms describe reviewing binders, policies, and endorsements against the terms negotiated with the insurer. ¹¹Company-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.

You request a quote online or by phone; if a client contract requires E&O, Harper says it places coverage matching that requirement and issues the certificate the same day. ³Company-reported. Professional liability page quote form and FAQ 'My client contract requires E&O. What now?'.

WTW's North American terms say an insurer quote is not confirmation of coverage; if the client orders binding, WTW seeks a formal insurer commitment, typically a binder. ¹¹Company-reported. Applies to placements governed by the cited North American Corporate Risk & Broking terms. It does not establish a self-service quote route or promise coverage availability for this line.
