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

ProBiz Revenue and Industry Fit

Markel’s miscellaneous E&O offering is described for small businesses in its ProBiz target industries, with the source identifying businesses up to $5 million in revenue. Insureon describes professional liability for service businesses but does not set an equivalent revenue threshold; eligibility depends on its application and carrier appetite. A business near Markel’s stated revenue boundary should confirm whether the class and size fit before requesting comparable terms through Insureon. [4] [3]

Published E&O Limit Ceiling

Markel states a maximum E&O limit of $2 million, while warning that the product-page maximum is not a promise that each buyer can obtain it. Insureon’s overview gives no limit figure. If a client contract sets a required limit, ask both providers for the available per-claim and aggregate amounts, deductible, and any sublimits rather than comparing the stated cap to an unspecified quote. [4] [3]

Contact for Placement

Markel invites prospective buyers or brokers to contact its team, while Insureon provides an online quote request. Neither overview names the insurer for an individual proposal or establishes binding timing. Request the proposed form and insurer alongside the quote. [4] [3]
