Design Firm Insurance

I run a small design firm and have had a terrible time securing insurance for a multi service design agency. I offer ID, Graphics, Interior and Web.
The insurance companies I have found only seem to offer policies for single disciplines. As a result my current policy technically only covers the interior design that my firm offers.
Anyone found otherwise?

All help much appreciated.
Thank you.

Have you tried IDSA?
I’m not sure how insurance companies (as you’ve discovered) cover multi disciplinary consultancies, but I do know they offer/have sources of industrial design insurance .
