Insulation Rebates Brooklyn NY

2026 guide · Updated October 2026 · 5 min read

Spray foam insulation already pays for itself in three to six years on energy savings alone. Rebates and tax credits make the math even better — we've seen Brooklyn customers cut their net project cost by 15–30% by stacking the available programs. Here's what's out there, how each one works, and how to actually claim the money. Programs change, so treat this as your map and confirm the current details during your free estimate.

National Grid Energy Efficiency Programs

National Grid is the gas utility for most of Brooklyn, and its energy efficiency programs have historically offered rebates for insulation upgrades that reduce heating load. These programs typically work through approved contractors and require documentation of the work — the insulation type, the area covered, and the before/after efficiency improvement. The exact rebate amounts and qualifying measures change from year to year, so the smart move is to ask us what's current before you schedule: we track the active programs and will tell you whether your project qualifies and what paperwork you'll need.

Federal Tax Credits for Insulation

The federal 25C energy-efficient home improvement tax credit has covered insulation upgrades at 30% of the project cost up to annual caps. Spray foam attic, wall, and basement insulation in a primary residence has qualified under this credit in past tax years. Important caveats: tax law changes, caps and percentages shift, and your eligibility depends on your tax situation. Confirm the current rules with the IRS or your tax preparer — and keep your contractor's itemized invoice, because you'll need it to claim the credit.

Con Edison and NYSERDA Programs

Con Edison, which handles electric service across the borough, has run efficiency programs aimed at reducing peak electric demand — relevant if your insulation project cuts summer cooling load, which spray foam absolutely does. NYSERDA (the New York State Energy Research and Development Authority) periodically offers incentives for residential energy improvements as well. These programs come and go; a quick check of current offerings before your project starts can surface money most homeowners never hear about.

How to Claim: The Paperwork That Gets You Paid

• Get an itemized invoice — foam type, thickness in inches, square footage, and total cost. Rebate programs and the IRS both want specifics, not a one-line total.
• Apply before or right after the work — some utility programs require pre-approval or enrollment before installation. Ask first.
• Keep everything — invoices, program application confirmations, and your tax documents for the year you claim the credit.
• Stack programs where allowed — utility rebates and federal credits can often be combined, which is how customers reach that 15–30% net savings.
• Confirm current rules — programs, amounts, and eligibility change. What was true last year may not be true this year.

The Bottom Line on Net Cost

A $6,000 attic-and-basement job that qualifies for a utility rebate plus a federal tax credit can land closer to $4,200–$5,100 out of pocket — and then the 30–40% energy savings start paying down the rest. That's why we bring up incentives at every estimate instead of waiting to be asked.
