License Renewal

Information About Renewal Applications for All Licenses

Plumbing/HVACR licenses expire on October 31 of even years (e.g., 2018, 2020).

Several weeks before the permit expiration date, a renewal notice will be sent to the email address on the record. This notice will explain how to access the online renewal application. To complete the online renewal application, you must use a credit card to pay your renewal fee.

Please keep your contact information in our records up-to-date so that notices we send will reach you.  To check and update your contact information online, click Change Contact Information.


Renewing a Lapsed License

If you fail to complete renewal by the expiration date, your license will expire. It is illegal to practice in Delaware while your license is lapsed.

You may file a late renewal application for up to one year after the expiration date. You must pay a late fee in addition to the renewal fee. Even though you can file a late renewal application, it is illegal to practice until the license is actually renewed. The late period is not a “grace period.”

If you fail to renew by the end of the one-year period, your license will terminate. To resume practicing in Delaware after termination, you must reapply for licensure.


Requesting Inactive Status/Reactivating

If you are not practicing in Delaware, you may request inactive status. To place your license in inactive status, submit a written request and the required status change fee to the Board. Your license may remain in inactive status for up to five years. You are not permitted to practice in Delaware while your license is inactive.

To reactivate an inactive Plumber license, see 24 Del. C. §1812(d). To reactivate an HVACR license, see 24 Del. C. §1825(d).
