Information About Renewals

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

A few months before the expiration date of your license, a renewal notice will be sent to the email address on the record. This notice will explain how to access your online renewal application in DELPROS, our online professional licensure system. To complete the online renewal application, you must log-in to your account, answer questions, and use a credit card to pay your renewal fee.

All notices about professional licenses, such as renewal and audit notices, will be sent by email only. It is important to keep your contact information up-to-date so that all the notices we send reach you. To check and update your contact information online, click on Manage Profile link in DELPROS.

Renewing an Expired License

If you do not renew your license by the expiration date, your license will expire. It is illegal to practice in Delaware while your license is expired.

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 within one year after the expiration date, your license will terminate. To resume practicing in Delaware, you must reapply in DELPROS as a new applicant.

For more information on renewing an expired license, see section §1812 in the Plumbing License Law or section §1825 in the HVACR License Law.

Inactive and Reactivating Licenses

If you hold an active license but are not practicing in Delaware, you may request to place your license on inactive status by submitting a Service Request in DELPROS. You must request inactive status before your late renewal period ends (October 31 of odd years).  You cannot practice in Delaware while your license is in inactive status. Your license may remain in inactive status for up to five years.

To resume practicing in Delaware, you must reactivate your license by submitting a Service Request in DELPROS, see DELPROS Service Requests Guide.

If you fail to reactivate during the five-year period, your license will terminate. If you wish to resume practicing after your license has terminated, you must reapply in DELPROS as a new applicant.

For more information on inactivation/reactivation, see section §1812 in the Plumbing License Law or section §1825 in the HVACR License Law.
