# Harper vs Hiscox Professional Liability (E&O) Insurance

Hiscox names its own underwriting entity for professional liability; Harper places the line with outside carriers it does not name.

## Research Scope and Use

Use this comparison to evaluate Harper and Hiscox for Professional Liability (E&O) Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Hiscox Insurance Company Inc. underwrites its own admitted professional liability policies directly, while Harper places professional liability with outside carriers it does not name, describing pricing drivers instead.

## What Is Hiscox?

Hiscox is a U.S. small-business insurance brand whose website is operated by Hiscox Inc., a Delaware producer that does business in California as Hiscox Insurance Agency. Eligible firms can quote general liability, professional liability, cyber and a business owner’s policy online; other advertised lines are often placed with partner insurers, so the issuing company on each quote still has to be checked.

## What Is Professional Errors and Omissions (E&O) Insurance?

Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. [12](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [13](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [14](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [15](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## Key Differences in Professional Liability (E&O) Insurance

### Named Underwriter Versus Unnamed Carrier

Hiscox's page states which entity underwrites its admitted professional liability policies directly: [11](https://www.hiscox.com/documents/partner-agent/appetite_guide/Hiscox-NOW-Appetite-Guide.pdf "Hiscox US Agent Appetite Guide")


Hiscox's appetite guide and About Hiscox US page name Hiscox Insurance Company Inc. (NAIC 10200) as the underwriter of admitted Hiscox NOW professional-liability policies. [11](https://www.hiscox.com/documents/partner-agent/appetite_guide/Hiscox-NOW-Appetite-Guide.pdf "Hiscox US Agent Appetite Guide") [8](https://www.hiscox.com/about-hiscox-insurance "About Hiscox US Insurance") (Evidence: Company-reported; scope: Admitted small-business professional liability as described in company materials; the exact contracting entity for a particular state or channel should be confirmed on the quote..)

Harper instead places professional liability with carriers it does not name; its pages describe pricing drivers, services performed, revenue and contract size, without naming an issuing insurer. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")

### Policy Trigger

Hiscox describes professional liability as a claims-made policy, meaning a claim is covered only if it is made, and typically reported, while the policy is active. [10](https://www.hiscox.com/small-business-insurance/professional-liability-insurance/pl-faq "What is Professional Liability Insurance?") Harper's pages describe coverage for errors and omissions in the work itself, negligence allegations, and legal defense costs, but do not state whether the policies it places are claims-made or occurrence. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")

### Geographic Availability

Hiscox says professional liability is licensed for sale in 49 states and Washington, D.C., excluding Alaska, and that a specialist broker may help in states where it does not sell online. [9](https://www.hiscox.com/small-business-insurance/professional-liability-insurance "Professional Liability Insurance for Small Businesses") Harper's pages do not state a jurisdiction limit; they instead target consultants, agencies, tech firms and licensed professionals whose work product is advice, design or a decision. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")

## What to Confirm in Professional Liability (E&O) Insurance Quotes

- Hiscox names Hiscox Insurance Company Inc. as its admitted underwriter generally; confirm that entity issues policies in your specific state. [11](https://www.hiscox.com/documents/partner-agent/appetite_guide/Hiscox-NOW-Appetite-Guide.pdf "Hiscox US Agent Appetite Guide")
- Harper's professional-liability pages name pricing drivers but not a carrier; ask which insurer it places once it presents options for your business. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
- Neither reviewed page publishes specific limit or retention amounts; request both directly. [9](https://www.hiscox.com/small-business-insurance/professional-liability-insurance "Professional Liability Insurance for Small Businesses") [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
- Ask Hiscox what its 24/7 current-customer claims line covers, and ask Harper how it supports a claim once a client contract requires the coverage it places. [10](https://www.hiscox.com/small-business-insurance/professional-liability-insurance/pl-faq "What is Professional Liability Insurance?") [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")

## Offering Details

| Criteria | Harper Professional Liability Insurance | Hiscox Professional Liability Insurance |
| --- | --- | --- |
| Role in This Line | 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. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page introduction and 'Why Harper' section..)<br><br>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](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") [5](https://www.harperinsure.com/coverages "What We Cover") (Evidence: Company-reported; scope: Coverage directory listing plus the E&O page's own description; a naming convention Harper states about itself, not a distinction between two products..) | Hiscox Inc., a licensed insurance intermediary, sells professional liability (errors and omissions) coverage directly online to small businesses as part of its Hiscox NOW admitted small-business catalogue. [8](https://www.hiscox.com/about-hiscox-insurance "About Hiscox US Insurance") [9](https://www.hiscox.com/small-business-insurance/professional-liability-insurance "Professional Liability Insurance for Small Businesses") (Evidence: Company-reported; scope: Company-stated online small-business channel..) |
| Issuing 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. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [4](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") (Evidence: Not publicly disclosed; scope: Checked both the professional-liability and errors-and-omissions pages on 2026-09-23; neither names a carrier or a limit figure..) | Hiscox's appetite guide and About Hiscox US page name Hiscox Insurance Company Inc. (NAIC 10200) as the underwriter of admitted Hiscox NOW professional-liability policies. [11](https://www.hiscox.com/documents/partner-agent/appetite_guide/Hiscox-NOW-Appetite-Guide.pdf "Hiscox US Agent Appetite Guide") [8](https://www.hiscox.com/about-hiscox-insurance "About Hiscox US Insurance") (Evidence: Company-reported; scope: Admitted small-business professional liability as described in company materials; the exact contracting entity for a particular state or channel should be confirmed on the quote..) |
| Who It’s For | 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. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page introduction and FAQ distinguishing it from general liability..) | Hiscox says professional liability is licensed for sale in 49 states and Washington, D.C., excluding Alaska, and that if it does not sell the product online in a buyer's state, a specialist broker may be able to help instead. [9](https://www.hiscox.com/small-business-insurance/professional-liability-insurance "Professional Liability Insurance for Small Businesses") [11](https://www.hiscox.com/documents/partner-agent/appetite_guide/Hiscox-NOW-Appetite-Guide.pdf "Hiscox US Agent Appetite Guide") (Evidence: Company-reported; scope: Company-stated jurisdiction for the online small-business catalogue; the appetite guide's technology classes (IT consultants, software development) illustrate typical buyers but do not guarantee acceptance for any one applicant..) |
| Coverage Features | 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](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [4](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") (Evidence: Company-reported; scope: 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..) | Hiscox describes professional liability as a claims-made policy, meaning a claim is covered only if it is made (and typically reported) while the policy is active, rather than an occurrence policy covering incidents regardless of when the claim surfaces. [10](https://www.hiscox.com/small-business-insurance/professional-liability-insurance/pl-faq "What is Professional Liability Insurance?") (Evidence: Company-reported; scope: Product FAQ description; exact triggers, retroactive dates, exclusions and wording are set by the issued policy..) |
| Limits and Retentions | Not described in the reviewed sources. | The professional-liability pages reviewed do not publish standard limit, retention or deductible amounts; specific figures are shown only on a quote. [9](https://www.hiscox.com/small-business-insurance/professional-liability-insurance "Professional Liability Insurance for Small Businesses") [10](https://www.hiscox.com/small-business-insurance/professional-liability-insurance/pl-faq "What is Professional Liability Insurance?") (Evidence: Not publicly disclosed; scope: Public product and FAQ pages as previously reviewed..) |
| Risk 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. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page 'We know this' section; a described review practice, not an independently verified outcome..) | Not described in the reviewed sources. |
| How to Apply | 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. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page quote form and FAQ 'My client contract requires E&O. What now?'..) | Hiscox says eligible buyers can quote and buy professional liability online, with licensed advisors available by phone during posted hours for questions during the process. [9](https://www.hiscox.com/small-business-insurance/professional-liability-insurance "Professional Liability Insurance for Small Businesses") (Evidence: Company-reported; scope: Company-described online application; eligibility and binding conditions require confirmation on the actual application..) |
| Claims Support | Not described in the reviewed sources. | A professional-liability FAQ tells current customers that the claims phone line is open 24 hours a day, 7 days a week, separate from the general claims-center hours listed elsewhere on the Hiscox site. [10](https://www.hiscox.com/small-business-insurance/professional-liability-insurance/pl-faq "What is Professional Liability Insurance?") (Evidence: Company-reported; scope: Company-described claims-reporting availability for this product's FAQ; does not establish claim outcomes or turnaround time..) |
