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.

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.
Buyer questions answered
- What is a retroactive date?
A retroactive date is the prior-acts boundary on a claims-made policy: services performed before that date may fall outside coverage even when the claim arrives during the current policy.
- Do architects need professional liability insurance?
Most architecture firms carry professional liability insurance because clients, owners and contracts commonly ask for it and because design-error allegations can arise years after a project closes.
- Does general liability cover design errors?
Generally no: general liability is not a substitute for professional liability when the allegation is a design error.
- Can a client be named as an additional insured on professional liability?
Usually not: additional-insured status is typically a general liability request, and professional liability policies generally do not add clients as additional insureds.
