The Residential High Efficiency Rebate Program provides rebates to residential owners and customers of Laclede Gas Company and Missouri Natural Gas Company for the installation of high efficiency heating systems and thermostats:


Programmable setback thermostats purchased and installed prior to February 26, 2011 must be ENERGY STAR® qualified.

Rebates on water heating equipment valid for units purchased and installed on or after February 26, 2011.

Owners of, or customers living in, an individually metered dwelling unit, are eligible to participate in this program and must apply for rebates through Energy Federation Incorporated (EFI) with or without the assistance of your heating, ventilating, and air conditioning (“HVAC”) contractor.

Rebate Limit: Individual dwelling units, as determined by account number, whether owner-occupied or rental property, are eligible for a maximum of two heating system rebates, two programmable setback thermostat rebates, and one water heater rebate under this program.

Owners of multiple individually metered dwelling units are limited to a maximum of 50 heating system rebates, 50 programmable setback thermostat rebates, and 50 water heater rebates during one program year.
