How is Professional Liability (E&O) priced for Directional Boring Contractors?

Inside a specialty trade class, base rates can vary 15-30% between carriers writing the same risk, which is why placement strategy matters.

On top of base rates, underwriters apply experience modifiers (3-year loss history), schedule rating credits/debits, and any state-mandated adjustments. The result is your final premium — and the gap between the cheapest and most expensive carrier on the same risk is often material.
