Key Differences in Professional Liability (E&O) Insurance
Profession range and buying model
Aon names law, accounting and consulting firms for its professional services practice; Mylo compares offers across insurers and gives examples from app development to beauty services. Ask Aon about its advisory placement if your firm fits its named practice, and ask Mylo which carriers consider your specific work. 3 6
Claims-made and occurrence forms
Mylo explains that E&O can be claims-made or occurrence-based and that tail coverage can extend reporting after a claims-made policy ends. Aon says it tailors coverage structures but does not set out those form choices in its reviewed summary, so request each offered form and retroactive date before comparing. 3 6
Quote comparison and customization
Aon describes tailored professional-liability structures; Mylo says it compares quotes and recommends coverage customized to the business. Ask each which insurer, limits and reporting terms are in the proposal, since Mylo does not underwrite and Aon’s summary does not name a carrier. 3 6
