## What Are Surety Bonds?

A surety bond guarantees that your business meets a specific obligation to a customer, contracting party or government agency. If a contract, license or permit requires one, get its exact form and amount; a bond is not insurance for your own losses. [10](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [11](https://www.sba.gov/funding-programs/surety-bonds "Surety bonds") [12](https://www.law.cornell.edu/uscode/text/40/3131 "40 U.S. Code § 3131 — Bonds of contractors of public buildings or works") [13](https://www.chubb.com/us-en/surety.html "Surety Bonds") [14](https://www.harperinsure.com/coverages/surety-bonds "Surety Bonds Insurance")

## What Are the Key Differences Between Gallagher and Marsh McLennan Agency Surety Bonds?

### Commercial and Contract Bond Categories

Gallagher separates commercial surety—license-and-permit, court, public-official, and customs bonds—from contract surety for construction. Marsh McLennan Agency’s page names both contract surety and commercial license-and-permit programs, but does not enumerate the same commercial bond types. If your requirement is a court, customs, or public-official bond, Gallagher’s overview identifies those categories explicitly; ask MMA whether it places that exact form before assuming the broad commercial label covers it. [6](https://www.ajg.com/insurance/commercial-surety-bonds/ "Surety") [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk | MMA")

### Letters of Credit and Placement Support

Gallagher says its surety team can work with an existing program, facilitate collateral release, and replace letters of credit with bonds; it cites a client transaction supporting $60 million in power-purchase obligations. MMA describes customized support for complex risks but does not specify letter-of-credit replacement in the reviewed overview. For a business trying to free bank capacity, Gallagher’s documented service is directly relevant; ask both brokers how the obligee would accept a bond and what collateral or indemnity the surety requires. [6](https://www.ajg.com/insurance/commercial-surety-bonds/ "Surety") [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk | MMA")

- Does MMA place your exact commercial bond form, and can its proposed surety replace the existing bank instrument? [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk | MMA")

## Gallagher vs Marsh McLennan Agency Surety Bonds Compared

| Criteria | Gallagher Commercial Surety Bonds | Marsh McLennan Agency surety bonds (official overview) |
| --- | --- | --- |
| Role in This Line | Gallagher places commercial surety bonds as a three-party arrangement between the client (principal), the party requiring the bond (obligee) and a surety company; Gallagher brokers the bond rather than acting as the surety itself. [6](https://www.ajg.com/insurance/commercial-surety-bonds/ "Surety") (Evidence: Company-reported; scope: Group-level commercial surety practice page..) | Marsh McLennan Agency describes arranging surety bonds for the audience stated on the cited product page.

This is not a policy form or a universal eligibility statement..) |
| Coverage Features | Gallagher says it places license and permit bonds, court bonds, public official bonds and customs bonds under its commercial surety practice, distinct from contract (construction) surety bonds, which it treats as a separate related product. [6](https://www.ajg.com/insurance/commercial-surety-bonds/ "Surety") (Evidence: Company-reported; scope: Group-level commercial surety practice page; a service-menu description, not a specific bond's terms..) | The cited product page describes contract surety and commercial license-and-permit bonds, with the source describing customized support for complex risks. Marketing description only; actual coverage, exclusions, conditions, limits, and availability depend on the issued policy and jurisdiction.

[6](https://www.ajg.com/insurance/commercial-surety-bonds/ "Surety") (Evidence: Not publicly disclosed; scope: Checked the group-level commercial surety practice page..) | 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. [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk | MMA") (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 | Gallagher says its surety team can help replace letters of credit with bonds, work with a client's existing surety program, and facilitate collateral release, citing a case where it placed commercial surety bonds in place of letters of credit to support $60 million in power-purchase obligations for an energy-company client. [6](https://www.ajg.com/insurance/commercial-surety-bonds/ "Surety") (Evidence: Company-reported; scope: Group-level commercial surety practice page case study; a single company-reported example, not independently verified..) | Confirm in your quote. |

The page does not establish a quote, bind, or coverage-effective timeline.
