# Chubb vs Relm Insurance Professional Liability (E&O) Insurance

Chubb targets non-licensed professional-services firms with one bundled policy; Relm's E&O family targets emerging sectors like space and AI.

## Research Scope and Use

Use this comparison to evaluate Chubb and Relm Insurance 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

Chubb underwrites Pro ERM as a single policy bundling professional liability with media and cyber cover for non-licensed professional-services firms. Relm lists a family of E&O products, including specialized versions for accountants and financial institutions, aimed at emerging sectors like space, digital assets, AI and biotech, distributed through brokers. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance")

## What Is Chubb?

Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company.

## What Is Relm Insurance?

## 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. [8](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [9](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [10](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [11](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 Bundled Product Versus a Product Family

Chubb underwrites Pro ERM as a single policy that combines professional liability with media and cyber exposures. Relm instead lists a family of separate professional-liability products under one page, distinguishing a general E&O line from specialized versions for accountants, consultants, financial institutions, and other niches, each distributed for placement through brokers. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance")

### Who Each One Targets

Chubb names a defined set of non-licensed professional-services buyers for Pro ERM: consultants, event planners, design and marketing firms, staffing firms and travel agents. Relm instead frames its E&O eligibility around emerging sectors such as space, digital assets, AI and biotech, and offers a Miscellaneous E&O entry for niche fields like robotics consulting and space logistics that don't fit an established category. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance")

### Regulatory Context

Chubb's reviewed page does not address whether professional-liability coverage is legally required for any of its target buyers. Relm's page, in contrast, flags a regulatory driver behind two of its sub-products:

Relm notes that some professionals, including attorneys, are required by federal or state law to carry errors and omissions insurance, and that Financial Institutions Professional Indemnity is mandated by some regulators, including the UK's Financial Conduct Authority. [7](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance") (Evidence: Company-reported; scope: Professional Lines page; general regulatory context, not a jurisdiction-specific legal determination for a particular buyer..)

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

- Ask Relm's broker which of its E&O sub-products, general, accountants, consultants or financial institutions, applies to your business. [7](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance")
- Ask Chubb for the Pro ERM liability limit and retention beyond its stated 100% worldwide defense-cost coverage. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")
- Ask Relm's broker to name the issuing insurer for your specific E&O placement, since the reviewed page does not disclose one. [7](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance")
- Confirm whether your sector fits Chubb's non-licensed professional-services list or Relm's emerging-sector framing, since the two describe eligibility differently. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance")
