Areas of coverage

Harper

  • role: 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. Professional liability page introduction and 'Why Harper' section.company-reportedSource ↗
  • role: 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. Coverage directory listing plus the E&O page's own description; a naming convention Harper states about itself, not a distinction between two products.company-reportedSource ↗Source ↗
  • eligibility: 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. Professional liability page introduction and FAQ distinguishing it from general liability.company-reportedSource ↗
  • coverage: 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. 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.company-reportedSource ↗Source ↗
  • services: 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. Professional liability page 'We know this' section; a described review practice, not an independently verified outcome.company-reportedSource ↗
  • application: 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. Professional liability page quote form and FAQ 'My client contract requires E&O. What now?'.company-reportedSource ↗
  • insurer: 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. Checked both the professional-liability and errors-and-omissions pages on 2026-09-23; neither names a carrier or a limit figure.not-disclosedSource ↗Source ↗

WTW

  • role: Under WTW's North American Corporate Risk & Broking terms, WTW normally acts as the client's insurance intermediary for engagements governed by those terms. 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.company-reportedSource ↗
  • coverage: 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. 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.company-reportedSource ↗Source ↗
  • application: 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. 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.company-reportedSource ↗
  • services: WTW's North American terms describe reviewing binders, policies, and endorsements against the terms negotiated with the insurer. 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.company-reportedSource ↗
  • insurer: The reviewed WTW sources do not identify an issuing insurer for a specific professional errors omissions placement. 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.not-disclosedSource ↗Source ↗Source ↗
  • limits: The reviewed sources do not state a buyer-specific professional errors omissions limit, retention, or deductible. No limit or deductible is inferred from general marketing or WTW's brokerage role; the insurer's quote and issued forms control.not-disclosedSource ↗Source ↗Source ↗

What Are the Key Differences Between Harper and WTW Professional Liability (E&O) Insurance?

Matching the policy to client requirements

Harper says its specialist builds E&O around the applicant's actual services, matches limits to client-contract requirements and reviews policy exclusions line by line before purchase. WTW's terms describe reviewing binders, policies and endorsements against terms negotiated with insurers. If a client requires a particular limit or wording, ask Harper what it will match and ask WTW which contract provisions it will check in the final form. [2] [9]

Timing and placement channel

Harper says it can issue a certificate the same day when a client contract requires E&O, and accepts online or phone quote requests. WTW's terms describe seeking formal insurer commitment, typically a binder, after the client orders binding. Confirm with Harper what information supports same-day issuance and with WTW how quickly the carrier can commit for your risk. [2] [9]

What Should You Confirm in Harper and WTW Professional Liability (E&O) Insurance Quotes?

  • Ask Harper which limits satisfy your client contract and request a copy of exclusions and the certificate deadline. [2]

  • Ask WTW who reviews exclusions and endorsements, and when the insurer can provide a binder. [9]

Harper says it tailors E&O limits to contract requirements and reads exclusions before purchase, with online or phone quotes. WTW identifies professional-liability solutions in FINEX and reviews policy wording against negotiated terms.
