Savings for Home Insulation Upgrades

Through the Ameren Illinois Energy Efficiency Program, eligible customers can get discounts on home insulation upgrades to decrease energy usage, improve home comfort and reduce energy costs.

The first step to take towards energy savings for home upgrades starts with a Home Energy Assessment. During the Assessment, a trained and certified Program Ally contractor is looking at your home for energy-saving opportunities and common home improvements including insulation, air sealing, ventilation and more.

Depending on the results of the Assessment, the Program Ally contractor may provide you with an energy efficiency project application that estimates project discounts and out-of-pocket costs.

Once you and your Program Ally agree to a home efficiency project right for your home, the Program Ally finishes the project. Finally, relax comfortably knowing you’ve taken control of your energy usage and reduced your energy costs.

How to Get Started

You are eligible if you meet the following qualifications:

  • Live in a single-family home. (A single-family home is a free-standing residential building. Single-family homes are designed to be used as a single-dwelling house or duplex.)
  • Must be an Ameren Illinois residential customer heating your home with gas or electricity delivered by Ameren Illinois.
    Must be an Ameren Illinois residential electric customer heating your home with propane.
