Temporary Plumber or HVACR

Title 24 § 1831 entitles Plumbing or HVACR businesses to designate either an owner or employee to temporarily continue providing the plumbing or HVACR services when they suffer a loss of its sole license holder due to a death or loss of employment. The maximum time for this temporary license is 100 days.

If you can answer “yes” to both of the questions below, the designated owner/employee may be eligible to apply for a temporary license.

  1. Has your firm suffered the loss of its sole license holder? AND
  2. Are you either an owner or an employee who wishes to temporarily continue providing the plumbing or HVACR services for the firm?

DELPROS allows you to save your incomplete application and return to it later to finish the process. You only have six (6) months to submit your application once you begin.

  • If you do not submit your application within six months of starting it, you will be required to restart the entire online application again.

You may check the status of your application online throughout the entire application process by using the “View Application Status” feature in DELPROS on your e-License dashboard.


  1. Know the requirements for the license you are pursuing.
  2. Request and gather all documents required to upload on the Attachments page. All information and forms are located on your profession’s webpages.


On the ATTACHMENTS page of your application, you may be instructed to:

  • either “attach” or “upload” the required document(s) directly to your application. This means you will find the document(s) saved on your computer or device and upload it to your application.
  • click “acknowledge.” This means you will either have to mail the documents yourself or request the “third-party” mail the document(s) directly to the Board office.
    • Examples of “third-party forms” are transcripts from schools, employment verifications from a supervisor, and license verifications from another state.
  • Forms requiring a supervisor signature, seal, or notary may have to be MAILED to the Board office directly UNLESS the document specifically indicates to UPLOAD the document.

The requirements for this license type are provided in the following section(s).


In addition to submitting the Temporary Plumber or HVACR application and fee in DELPROS, you must submit:

  • A “non-temporary” Plumber or HVACR application and fee
  • A death certificate or termination of employment document
  • A Notice of Loss (explanation about firm’s loss of sole license holder)

The applicant must take the next available examination. Click on Examinations for the Delaware exam schedule. If the applicant either fails to take the next available examination or fails to pass the examination, the temporary license expires immediately.

The temporary license expires in 100 days or when full Plumber or HVACR licensure is issued, whichever is earliest.
