Apply to join QCN contractor network
Contractors can now apply to join the Qualified Contractor Network. The application is live only takes a few minutes to complete.
Commerce will review each application and notify you within 14 business days. Please be sure to include all the required documentation:
- Copy of your business license
- Trade license and certifications for the type of work you want to do
- Insurance and surety bond documentation
Once the statewide rebate administrator is onboarded, they will reach out to you to schedule training and get your payment information. They will also add you to the Find-a-Contractor list.
Our search for a rebate administrator is over
We're one step closer to having a rebate administrator. Commerce has asked the Department of Energy for approval to contract with the rebate administrator selected through the state procurement process.
Why it matters: The rebate administrator is responsible for accepting rebate applications from households, training and paying contractors.
What’s next: Commerce has submitted for federal approval to contract with the rebate administrator. Once approval is received, the public will be notified. If you have any questions about the QCN, please contact us through our new support form.
