What Is Umbrella and Excess Liability Insurance?
Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them. 7,8,9,10,11
Key Differences in Umbrella and Excess Liability Insurance
Exposure Profile and Limit Advice
Relm frames excess liability for businesses with higher-than-average exposure, including large fleets, substantial public interaction or large contracts, and highlights energy, manufacturing and transportation. Liberty Mutual names umbrella/excess on a wholesale industry list, but its reviewed record does not state a comparable exposure profile. Relm’s page gives buyers concrete reasons to discuss excess capacity; confirm that its appetite matches your actual operations. 3 6
Broker Guidance and Product Detail
Relm says brokers advise clients on exact excess limits and describes coverage once underlying liability limits are exhausted. Liberty Mutual lists the coverage option but does not publish limit or attachment details in the cited pages. For both, request the underlying policies and proposed exhaustion point; for Liberty Mutual, also ask which limit layers are available. 3 6
