What disqualifies you

The rules people find out about after the work is done.

  • Insulation not installed by a licensed insulation contractor, or installed outside 2026.
  • A second heat pump water heater rebate on the same account in the 2024-2026 period.
  • A heat pump water heater without a wireless, programmable timer or controller.

The thing most pages get wrong

TEP's water heater and thermostat rebates run on a 2024-2026 program period: equipment must be bought and installed during 2024-2026, and an account gets one water heater rebate per period. The insulation rebate is for 2026 installations. Waiting until 2027 risks missing the current terms.

Lifeline discount

TEP's Lifeline program takes $20 a month off the bill for customers at or below 200% of the poverty guidelines.

A check, not a discount

Unlike SRP, which applies its insulation rebate on the contractor's invoice, TEP mails a check six to eight weeks after you apply, and its water heater rebate arrives as a credit on your TEP account after a representative has verified the installation.
