SMUD lists a contractor-installed package. PG&E's rebates page lists no insulation rebate.

- SoCalGas. The rebate table on its Rebates & Incentives page lists no insulation. Its 2026 rebate application lists attic and wall rebates only for customers affected by the 2025 Southern California wildfires in listed ZIP codes, in homes with a natural gas furnace, postmarked by December 31, 2026. See the SoCalGas insulation rebates page.
- SCE. SCE's rebates page lists no insulation rebate and limits Home Performance Plus to single-family detached homes, or units in buildings of up to four units, within Disadvantaged or Low-Income communities. The Home Performance Plus rebates page gives the amounts and requires central air with a gas furnace, a central heat pump, or electric heat with no cooling. See insulation rebates in SCE territory.
- SMUD. The Seal and insulate page lists air-sealing to SMUD program standards, new sealed ductwork, and attic insulation with deep-buried ductwork. You must select a Home Performance Program contractor, who submits the rebate. Neither that page nor SMUD's heating and cooling rebates page states an amount for insulation alone.
How Does the LADWP Insulation Rebate Work?
LADWP pays per square foot for batt or roll attic insulation bought and installed since September 1, 2025, once per residence every 15 years.
LADWP's Attic Insulation Rebate Program page says the rebate cannot exceed 80% of the insulation material, permit and installation costs. The extra $0.25 per square foot is listed as a launch special that has been extended, with no end date given. The home must have air conditioning.
You need a paid invoice, the product rating certificate, before-and-after photos and a finaled Building and Safety permit, postmarked within 12 months of purchase or installation.
The insulation rebates savings guide works through 3 attic sizes, and the Los Angeles page covers the application.
Can I Get Insulation for Free in California?
Possibly, if your household is income-qualified. PG&E's Energy Savings Assistance flyer says common no-cost improvements may include insulation and weatherproofing, for owners and renters.
PG&E's Energy Savings Assistance flyer says the house, apartment or mobile home must be at least five years old. It is marked valid through May 31, 2027.
The state's Low-Income Weatherization Program page describes no-cost solar PV and energy efficiency upgrades for low-income households, with components for farmworker housing and multi-family properties.
The weatherization income guidelines cover the income limits, and the eligibility check shows which programs may fit a household.
Has the Federal Insulation Tax Credit Ended?
Yes. The federal 25C credit, which covered insulation and air sealing, ended for property placed in service after December 31, 2025.
See the federal home energy tax credits that ended. ENERGY STAR's recommended attic levels are in the insulation R-value chart.
