Ventura County homeowners have one regional program that pays for insulation in 2026: 3C-REN, the regional energy network for Ventura, Santa Barbara and San Luis Obispo counties. Income-qualified SCE customers can also get weatherization at no cost.
3C-REN doesn't publish its incentive amounts on its website, so this page doesn't either. Here's what each official page showed on October 10, 2026.
Is There an Insulation Rebate in Ventura County?
Yes. 3C-REN says its incentives are available as of January 1, 2026, and its Single-Family program covers efficiency upgrades including insulation, heat pump water heaters and heat pump heating and cooling. It serves single-family homes of 1–4 units in Ventura, Santa Barbara and San Luis Obispo counties.
To take part, submit 3C-REN's interest form to get connected with enrolled contractors, or pick a contractor from its directory. 3C-REN's pages don't list dollar amounts; the contractor or 3C-REN can tell you what your project qualifies for.
Is the Double Incentive Still Available?
No. 3C-REN's August 2026 newsletter said single-family participants could receive up to double the incentives for Ventura County projects completed by September 30, 2026. That date has passed.
The same newsletter said incentives are higher for customers who meet equity criteria. Ask 3C-REN what applies to your household now.
Can I Get Free Insulation Through SCE?
Possibly, if your household is income-qualified. SCE's Energy Savings Assistance page lists weatherization services among the upgrades it may provide free to homeowners and renters who qualify. SCE notes that services may not be available in all areas.
After income qualification, an SCE-approved contractor walks through the home to see which upgrades fit.
Do SCE or SoCalGas Have an Insulation Rebate?
Not on their rebate pages. On October 10, 2026, neither SCE's marketplace page nor SoCalGas's rebates page listed an insulation rebate. The federal 25C credit, which covered insulation, ended for property placed in service after December 31, 2025.
