## 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.

## What Are the Key Differences Between Corgi and Nationwide Umbrella and Excess Liability Insurance?

### Underlying Coverage and Form

Corgi shows an illustrative $5 million per-occurrence and aggregate umbrella layer with no self-insured retention above scheduled underlying limits. Nationwide’s overview describes an added layer but publishes no standard limit or retention. Treat Corgi’s figures as an example, then request an actual quote from both with the same attachment point and scheduled policies. [6](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance") [10](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide")

### Limits, Eligibility, and Buying

Corgi describes its umbrella as occurrence-based and follow-form, attaching after scheduled CGL, hired-auto or EPLI limits are exhausted; it lists six extension scenarios, including products-completed operations and aggregate refresh. Nationwide says the layer sits above underlying policies such as general liability or business auto but leaves terms to the quote. Ask Nationwide to specify which underlying lines it will schedule and compare exclusions and drop-down wording with Corgi’s form. [6](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance") [10](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide")

### Support to Confirm

Corgi lists a 1–14 day turnaround for commercial umbrella, separate from its instant-quote products. Nationwide directs buyers to an agent or quote request. Ask Corgi what information starts the review and ask Nationwide for its expected quote and binding steps; neither route’s public description guarantees a binding date. [6](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance") [10](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide")

## What Should You Confirm in Corgi and Nationwide Umbrella and Excess Liability Insurance Quotes?

- Ask Corgi and Nationwide to identify the actual issuing insurer, required scheduled underlying policies and limits, attachment point, and exclusions in the quote. [6](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance") [10](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide")

## Corgi vs Nationwide Umbrella and Excess Liability Insurance Compared

| Criteria | Corgi Commercial Umbrella Liability | Nationwide umbrella excess (official overview) |
| --- | --- | --- |
| Role in This Line | Corgi sells Commercial Umbrella as excess capacity that sits above a startup's scheduled underlying CGL, HNOA, and EPLI policies rather than as a standalone primary policy. [6](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance") (Evidence: Company-reported; scope: Umbrella product page description..) | Nationwide describes offering umbrella excess for the audience stated on the cited product page. [10](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide") (Evidence: Company-reported; scope: umbrella excess marketed by nationwide; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) |
| Issuing Insurer | The umbrella product page does not name the issuing carrier for this line; Corgi's general disclosures say coverage may be underwritten by affiliated or third-party carriers depending on product and jurisdiction, without identifying which entity covers umbrella specifically. [6](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance") (Evidence: Not publicly disclosed; scope: Umbrella product page as read on 2026-09-23, checked against the site's general underwriting disclosure language..) | Confirm in your quote. |

This is not a policy form or a universal eligibility statement..) |
| Coverage Features | Corgi describes the umbrella as occurrence-based and follow-form: it attaches once a scheduled underlying policy's per-occurrence or aggregate limit is exhausted, matches that policy's terms and exclusions, and can drop down to respond as primary if an underlying policy is unavailable due to insurer insolvency or aggregate exhaustion (but generally not for a coverage exclusion). [6](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance") (Evidence: Company-reported; scope: Umbrella product page glossary and FAQ; actual attachment and drop-down terms are set by the issued policy..)<br><br>Corgi lists six scenarios the umbrella extends to: CGL excess, hired-auto excess, EPLI excess, personal and advertising injury excess, products-completed operations excess, and CGL aggregate refresh. [6](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance") (Evidence: Company-reported; scope: Umbrella product page "Six Scenarios" section; each still requires the matching underlying policy to be in place and exhausted..) | The cited product page describes an added liability layer above underlying policies such as general liability or business auto; the page says terms and quote depend on the insured's business and underlying coverage. Marketing description only; actual coverage, exclusions, conditions, limits, and availability depend on the issued policy and jurisdiction.

| Limits and Retentions | Corgi's illustrative umbrella example shows a $5 million per-occurrence and $5 million aggregate layer with a $0 self-insured retention above the scheduled underlying limits. [6](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance") (Evidence: Company-reported; scope: Illustrative policy structure ('Anatomy of a $5M Umbrella Policy') on the product page; actual limits and retention depend on the issued policy and the schedule of underlying..) | The cited overview does not set a universal limit or retention for this line. Ask for the proposed policy form, limits, retentions, exclusions, and conditions in the quote. [10](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide") (Evidence: Not publicly disclosed; scope: Only the cited marketing page was reviewed for published limit and retention information; no policy-form entitlement is inferred..) |
| Risk Services | The reviewed umbrella page does not describe risk-management or loss-control services tied specifically to the umbrella layer. [6](https://www.corgi.insure/umbrella "Commercial Umbrella Insurance for Startups | Corgi Insurance") (Evidence: Not found in reviewed sources; scope: Umbrella product page as read on 2026-09-23..) | Confirm in your quote. |
| How to Apply | Corgi's homepage lists Commercial Umbrella Liability under specialty coverages with a 1-14 day turnaround, distinct from the policies marked for an instant online quote. [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") (Evidence: Company-reported; scope: Homepage policy-card labeling as of 2026-09-23..) | The page directs prospective customers to contact an agent or request a quote. The page does not establish a quote, bind, or coverage-effective timeline.
