First-Time Installer Certification

  • Installer certification went into full effect Jan. 1, 2018.
  • This requirement applies to the following energy efficiency measure criteria:
    • Any measure that requires an electrical connection
    • Any measure that will receive an incentive of $300 or more
  • Certified installers agree to comply with building and electrical codes and manufacturer's installation instructions.
  • Certification is only required when applicable measures are installed by a third-party external contractor; self-installed measures (those installed by an internal employee or staff member) are excluded from the certification requirement.
  • Incentives cannot be paid by the Program unless a certified installer is used. The Program must wait for confirmation of Ally certification before issuing payment to the Ally or the customer.

Installer Recertification

All 2018 ICC Certified Installers must become recertified by May 31, 2019 to avoid late fees. For information on how to become recertified, please visit

Recertification Reports are due to the Commission before June 1 of each year beginning in 2019. Please use the recertification report template found on the Illinois Commerce Commision Energy Efficiency Measures Installer Webpage.

As part of the recertification process, you will need to provide updated proof of insurance (made out to the Illinois Commerce Commission) and a number of business and residential measures installed in the previous year. This document must also be notarized.

If you became certified in 2019, you will not need to recertify by May 31, 2019. Your due date will be May 31, 2020. If you're unsure if you became certified in 2018 or 2019, your ICC-provided docket number will begin with the year (17, 18, or 19) in which you became certified. Please refer to the instructions below to find your docket number.

The recertification application will ask you for your ICC docket number. To find your docket number, please go to the ICC's website and search for your company name. On the search page, the last line of your listing will say the following: Activated *Docket Number* *Date*.

Additional Information

The Future Energy Jobs Act signed into law by the State of Illinois in December 2016 requires contractors who are installing energy efficiency measures to be certified. Per the legislation, only a "qualified person" may install select measures.

What if I am a Sole Proprietor instead of an LLC or Corporation and don’t have a listing on the Illinois Secretary of State website?
If you are a sole proprietor and are not registered with the State but rather a county or municipality, please provide proof of registration with your local government agency and the contact information for the agency. Please include this with your application sent to our program.

On the Certificate of Insurance, to whom do I make out the certificate holder section?
Please make the certificate holder out to:
Illinois Commerce Commission
527 E. Capitol Avenue
Springfield, IL 62701

We cannot submit any applications that do not have the Illinois Commerce Commission in the certificate holder section.

Our company has two different business names — which one do we need to include on the application?
You must apply under the exact company name that appears on the Secretary of State's website. If you have two companies registered with the State, you must submit separate certification applications for each company listed.

The recertification application asks for my docket number. Where do I find this?

Please see the recertification instructions dropdown on this page for information on how to find your docket number.
