I started the application process with the online application; however, I have not received my paper copy of my rebate application in the mail. Can I request another one?

Yes. Please call 800-356-5467 to request another copy of your rebate application.

I enrolled for one rebate, but I actually installed two qualifying products. Can I fill in the information for both products on the same application and submit the receipt for both qualifying products in the same envelope?

No. Each product must have its own application. Please note that the deadline to sign up for the Home Energy Rebates Program was March 31, 2018.

How will I receive my rebate?

Once your application is approved, a rebate check will be mailed to the service address on file with LG&E and KU. A rebate cannot be used as a credit toward your LG&E or KU account.

How long does it take to receive my rebate?

Once your application is approved, a rebate check will be mailed within six to eight weeks to the service address on file with LG&E and KU.

Can you mail my rebate check to another address?

No. Program requirements state that the rebate check must be mailed to the service address on file with LG&E and KU at the time the check is mailed.

How can I check on the status of my rebate?

You may sign in to My Account or call 800-356-5467 to check on the status of your application. If you call, follow the prompt for Home Energy Rebates and select '2' for questions about an existing rebate.

Are there proof of purchase requirements?

Yes. Retail purchase receipts must be legible and must include the following:

  • Retailer/Contractor name, address and phone number.
  • Itemized listing of product(s), including description(s), manufacturer(s), model number(s) or other identifying information. The receipt information must match the product information from the rebate application.
  • Product purchase price and proof that full payment has been made.
  • Purchase date and date product delivered or installed (if installed by a contractor).

Additional documentation is required for central air conditioner and air-source heat pump and replacement window and window film rebates.

What is the effective purchase date to be eligible for a rebate?

Qualifying appliances and products purchased between November 9, 2011 and March 31, 2018 that meet the proof of purchase requirements may qualify for rebates.

I am a builder or landlord who purchased an eligible product or appliance that was installed at the service address of a current LG&E or KU residential electric customer. Can I receive a rebate for this purchase?

Yes. As a builder or landlord, you may be eligible for a rebate through our third-party application process. Rebated items may be subject to on-site verification. To request a third-party application, please call 1-800-356-5467.

Where can I find the solar heat gain or shading coefficient for my window film?

If the coefficient is not found on the packaging and you self-installed the product, you may contact the manufacturer directly or visit the manufacturer's website to find the coefficient under the product specifications for your particular model. The Solar Heat Gain must be less than or equal to 0.45 or the Shading Coefficient must be less than or equal to 0.5.

I replaced my windows. Am I eligible for a rebate?

Not all replacement windows, even double and triple-pane windows, are eligible for rebates. To qualify, high-efficiency replacement windows that have a solar heat gain coefficient that is less than or equal to 0.45 or a shading coefficient that is less than or equal to 0.50. Additionally, your application must include a copy of the National Fenestration Rating Council (NFRC) certificate or label that can be obtained from the installation contractor. The NFRC certificate or label must list model numbers for the window. While many replacement windows can help seal your home, the payback period is very lengthy so often times it is not economical to make this investment.

I installed double- or triple-paned windows. Am I eligible for a rebate?

Regardless of how many panes your new windows have, they must meet the required solar heat gain or shading coefficient to qualify for this program. Windows or window film purchased since November 9, 2011 must have a solar heat gain coefficient that is less than or equal to 0.45 or a shading coefficient that is less than or equal to 0.50. If you are unsure if your windows meet these qualifications, check the National Fenestration Rating Council (NFRC) certificate or label which should have been provided by your window installer. This document is required to apply for our rebates.

I would like to apply for a high-efficiency window rebate. What is the required National Fenestration Rating Council certificate?

Window manufacturers are required to evaluate and rate their products according to a number of efficiency specifications. A couple of these ratings are known as the SHGC, or the Solar Heat Gain Coefficient, and the SC, or the Shading Coefficient.

The NFRC certificate or label, prepared by the independent, third-party laboratory called the National Fenestration Rating Council (NFRC), is the document that provides the most accurate ratings for your new windows.

Check with the contractor who installed your windows and request your NFRC certificate or label if it is not readily available in your documentation.

To learn more about the National Fenestration Rating Council, visit the NFRC official website.

I installed new windows, but they do not qualify for rebates. Why not?

Our rebate program is designed to help customers offset the purchase of high-efficiency products, so your windows must meet the required solar heat gain or shading coefficient with the specified documentation. We honor qualifying rebates for installations made after the date our program began, which was November 9, 2011.

To save energy and money, does LG&E and KU recommend installing new windows?

Old-fashioned, single-pane windows leak up to half of your heating and cooling energy, so upgrading to triple-, double- or even single-pane with qualifying window film is a way to keep heat in during the winter and heat out during the summer. That said, while many replacement windows can help seal your home, the expense is high and the payback period is lengthy so may not always be economical to make this investment. A low-cost way to save energy with your existing windows is to install high-efficiency window film or use interior drapes in winter and summer, particularly for windows located on the west and south sides of the house. For a recommendation that is customized for your home and a review of your specific energy usage, we recommend our Home Energy Analysis.

What is a rebate verification?

We perform random rebate verifications to ensure our rebates are properly awarded. If your rebate application is selected for verification, our program partner, MaGrann Associates, will call to schedule an appointment at your convenience. Someone from your home over the age of 18 will need to accompany our program partner during the appointment. The visit will last 10-15 minutes and the representative will confirm the make, model and serial numbers of the high-efficiency equipment you installed. We appreciate your understanding and patience if you are asked to participate in the rebate site verification process.

For high-efficiency replacement window rebates, why is an itemized receipt needed?

The rebate amount for the customer is based on the material cost of the windows before tax. Labor cost is not included in the rebate amount. For this reason, the receipt must be itemized and specify the material cost versus the installation cost.

What if I do not provide the NFRC label?

If a customer does not provide the NFRC label with the rebate application(s), a letter will be sent to the customer asking him or her to obtain this information from the vendor/ retailer. 

What if my window invoice doesn't include the model numbers of the replacement windows?

If an invoice with the itemized model numbers matching the NFRC label cannot be provided, it is acceptable to provide a message from your window retailer on company letterhead detailing the model number installed that directly ties to the NFRC label or specification data.
