What the features table shows

Each cell links to the carrier document it came from. Blank or unverified features appear as Ask us, because carriers publish different levels of detail.

Use the pair comparisons for a closer look at two carriers at a time, then request quotes so underwriting can confirm terms for your firm.

Which policy terms should you understand before comparing carriers?

Two terms change how every row in the table reads. Policy form decides which claims a policy answers: see claims-made vs occurrence for design professionals. Defense treatment decides whether legal costs reduce the limit available for damages: see defense inside vs outside policy limits.

Frequently asked questions

Which architects and engineers insurance company is best?

We do not rank carriers. The right fit depends on disciplines, revenue, contracts and claims history, and we quote multiple carriers from one application.

Where do these policy features come from?

Only from each carrier's own published product pages, fact sheets or brochures, cited in the table.

All buyer questions

What are the sources?

Policy forms and endorsements control; this is not legal advice or a coverage decision.

Carrier names identify markets quoted through our agency. Availability depends on underwriting, state, policy wording and endorsements; this is not an offer of coverage.
