What Are the Key Differences Between Alliance Risk and Chubb Professional Liability (E&O) Insurance?

Start With Your Professional License

Chubb’s Pro ERM is aimed at professional-services firms that are not licensed professionals:

Chubb says Pro ERM is available to non-licensed professional-services firms of all sizes, naming examples including associations, consultants, business process administrators, event planners, interior and graphic design firms, marketing and PR firms, printers, staffing firms, travel agents and trustees. ²Company-reported. Pro ERM Target Clients list.

Alliance Risk lists accountants and tax professionals, architects and engineers, and real estate and insurance agents among its target professions. If your work requires a professional license, check with Alliance Risk about eligibility before pursuing Chubb’s product. ¹

Contract Requirements and Claims-Made Support

Chubb lists automatic additional-insured status for clients when a contract requires it, plus disciplinary-proceedings defense. Alliance Risk describes broker services such as contract review and help structuring claims-made terms, including tail coverage and retroactive dates. The practical difference is built-in policy provisions versus help shaping the placement; ask which contract obligations each quote satisfies. ² ¹

How You Apply

Chubb routes Pro ERM through agents and brokers using its Cyber Central or Marketplace platforms. Alliance Risk offers a quote request but does not list a submission checklist for E&O. Ask each what information it needs so you can estimate the application work. ² ¹

What Should You Confirm in Alliance Risk and Chubb Professional Liability (E&O) Insurance Quotes?

Ask Chubb to confirm that your business meets the Pro ERM eligibility definition. ²
Ask Alliance Risk which carrier will issue your policy and whether it accepts your specific licensed work. ¹
Request the limit and retention on Chubb’s quote; its reviewed page does not publish a standard limit. ²
Ask Alliance Risk what documents it needs for submission. ¹
