What is a Surety Letter of Bond Ability?

Author: Mathew Manol

Contractors who are new to the world of performance bonding will often approach us when a project owner or general contractor wants to hire them on a project. As part of this process a project owner or general contactor will sometimes ask for a Letter of Bond Ability (also called a pre-qualification letter).

A letter of Bond Ability is a formal document provided by a bond company that indicates your firm has a performance bonding facility in place. It might also say what project limits the bonding company is comfortable supporting.

Owners and general contractors ask for this document to get comfortable that you have a performance bonding facility in place and can secure bid bonds, performance bonds and labour and material payment bonds, if needed.

Unlike a bid bond, performance bond or labour and material payment bond, a Letter of Bond Ability does not provide the owner or general contractor any protection and is instead just an indication of your ability to secure bonds, if needed.

It is also important to note that there is no cost for each Letter of Bond Ability. As part of establishing a surety facility, your firm will be charged an annual fee. This fee covers all the Letters of Bond Ability, Bid Bonds and Surety’s Consents. A premium will only be charged if you are awarded a project and require a performance bond and/or labour and material payment bond.
