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

Form and Coverage Scope

Aon describes professional liability as a structure tailored to a firm’s needs, naming law, accounting and consulting practices as its audience. Corgi positions Miscellaneous E&O as a catch-all for service businesses whose professional exposure is not addressed by its technology-, real-estate- or lawyer-specific products. Corgi describes claims alleging negligence, errors or failure to perform services. Buyers should check which Corgi product fits their profession before treating Miscellaneous E&O as a broad default. [1] [2]

Buyer Fit and Policy Terms

Corgi says this specialty product sits outside its instant-quote flow and is typically quoted in one to fourteen days; the reviewed pages publish no limit or policy structure and do not name its carrier. Aon’s page also omits quote limits and leaves the placement insurer to the account. Corgi’s reviewed pages do not describe risk-management or claims services for this product. Request the form, retroactive date, limit and claims contact from either path. [1] [2]

  • Ask Corgi whether your profession belongs in Miscellaneous E&O or a specialized product and who issues it. [1] [2]
  • Ask Aon for the proposed form, limits and expected placement steps for your profession. [1] [2]
