What Are the Key Differences Between Markel Insurance and WTW Professional Liability (E&O) Insurance?
A Product Offer and a Brokerage Practice
Markel describes its miscellaneous E&O product for targeted small businesses, including a stated $5 million revenue ceiling and $2 million maximum limit. WTW's reviewed record describes professional-liability solutions within FINEX and E&O among financial lines for residential real-estate stakeholders; it does not present a comparable standard small-business product or limit. The distinction is useful when deciding whether to request a defined small-business offer or a broker-designed placement for a particular sector. 3 8 7
Negotiation Through Issued Policy
WTW's North American terms say an insurer's quote is not confirmation of coverage; after a client orders binding, WTW seeks a formal insurer commitment, typically a binder, and reviews binders, policies, and endorsements against negotiated terms. Markel's public product page invites contact but does not describe a comparable brokerage document-review process. For a complex E&O placement, ask who checks the final issued policy against the proposal and who resolves discrepancies. 9 3
Limit and Market Questions
Markel gives buyers a public maximum of $2 million, whereas WTW's reviewed professional-liability sources do not publish an E&O limit. Ask WTW which insurer and form it would approach for your profession and whether its proposal can match the Markel limit; confirm both retention and retroactive date before weighing the offers. 3 8
