## 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

### One Catalogue Entry Versus Two

Gallagher lists a single Errors and Omissions Insurance page in its small-business catalogue. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") Harper instead markets the same underlying policy under two separate catalogue names:

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. [10](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") [11](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..)

### Market Commentary

Gallagher's page adds a market-conditions section saying the E&O market has seen consistent rate increases that have started to moderate, driven by higher claim frequency, litigation costs and more selective underwriting. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") Harper's professional-liability and errors-and-omissions pages do not include comparable market-trend commentary; they instead describe reading a policy's exclusions line by line before a client buys. [9](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")

### Who Each Page Names as a Fit

Gallagher recommends E&O for small businesses in technology, insurance, accounting, tax, wealth management and legal services, naming doctors, lawyers, accountants, nurses, caregivers, counselors, social workers and engineers as example professionals. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") Harper instead targets consultants, agencies, tech firms and licensed professionals whose work product is advice, design or a decision, distinguishing the line from general liability in its FAQ. [9](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")

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

- Neither Gallagher's nor Harper's pages name an issuing insurer; ask both which carrier would underwrite your policy. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") [9](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
- Ask Gallagher how its stated market conditions, rate increases and more selective underwriting, affect pricing for your specific profession. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance")
- Ask Harper for its exclusions review in writing before binding, since it describes reading exclusions line by line as part of its process. [9](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
- Neither page publishes E&O limits or premiums; request specific figures from both. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") [9](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")

## Offering Details

| Criteria | Gallagher Small Business Errors and Omissions Insurance | Harper Professional Liability Insurance |
| --- | --- | --- |
| Role in This Line | Gallagher Small Business arranges errors and omissions (E&O) coverage with partner carriers rather than underwriting the policy itself. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") (Evidence: Company-reported; scope: Gallagher Small Business's direct-to-small-business E&O product page..) | 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. [9](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. [10](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") [11](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..) |
| Issuing Insurer | The E&O product page does not name the insurer that would issue a given business's policy. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") (Evidence: Not publicly disclosed; scope: Checked the E&O product page on 2026-09-23..) | 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. [9](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [10](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..) |
| Who It’s For | Gallagher recommends E&O for small businesses that provide a specific professional service, naming technology, insurance, accounting, tax, wealth management and legal services, and lists doctors, lawyers, accountants, nurses, caregivers, counselors, social workers and engineers as example professionals; it also notes that many client contracts require carrying E&O. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") (Evidence: Company-reported; scope: Product page eligibility and recommended-professions lists; actual acceptance depends on underwriting..) | 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. [9](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..) |
| Coverage Features | Gallagher describes E&O as protecting against client charges of negligence or injury tied to professional services, covering losses, attorney fees and court costs regardless of fault, and specifically responding to alleged or actual negligence, personal injury, copyright infringement, punitive damages, and claims against past work, temporary staff or independent contractors. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") (Evidence: Company-reported; scope: Product page coverage description; the issued policy and its exclusions control. Note this record excludes medical malpractice, which the page treats as a separate specialized coverage covered under its own line..)<br><br>Gallagher's small-business team says the E&O market has seen consistent rate increases that have started to moderate, driven by higher claim frequency, litigation costs and a more litigious environment, and that insurers are more selective and require more detailed underwriting information. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") (Evidence: Company-reported; scope: Product page market-commentary section; a general market view, not a quote for any specific business..) | 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. [9](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [10](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..) |
| Limits and Retentions | The E&O product page does not publish limits, deductibles or premiums; it directs prospective buyers to request a quote instead. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") (Evidence: Not publicly disclosed; scope: Checked the E&O product page on 2026-09-23..) | Not described in the reviewed sources. |
| Risk Services | Not described in the reviewed sources. | 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. [9](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..) |
| How to Apply | Gallagher offers an online quote form, a small business advisor phone line (1-833-292-9441, Monday through Friday, 8 a.m. to 5 p.m., continental U.S.), and a scheduled callback request to start an E&O quote. [6](https://www.gallaghersmallbusiness.com/insurance-products/professional-liability-eo/ "Errors and Omissions Insurance") (Evidence: Company-reported; scope: Product page "Get Covered Now" section..) | 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. [9](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?'..) |
