What actually changes after the work is done.
Lower heating bills
Less fuel burned every winter, on a building you already own. Envelope work is one of the few upgrades that reduces operating cost without depending on tenant behavior.
Fewer tenant complaints
Cold top-floor units and drafty first floors are the two most common heat complaints in walk-up buildings. Both are envelope problems, not boiler problems.
Better NOI and valuation
Heating is an owner-paid expense in most pre-war multifamily buildings. Lower operating expense flows straight to net operating income, and NOI is what the building is valued on.
Over 25,000 sq ft? Local Law 97 puts a price on every ton of emissions over your cap. See what that means for your building
Three steps, and the paperwork isn't yours.
STEP 01
Share a recent gas bill
Just the account page. The bill confirms which utility serves the building and that the account is active — the two facts that decide which program applies. Nothing else is needed to start.
STEP 02
Eligibility check and walkthrough
Program eligibility is confirmed against the actual building, then a certified program specialist walks it: attic or cockloft access, wall construction, basement conditions, and existing insulation. This costs nothing and carries no obligation.
STEP 03
Paperwork handled, then install
The program application, scope documentation, and post-installation inspection paperwork are prepared and submitted for you. You approve the scope before any work is scheduled.
Independent by design. Here's exactly how.
We are not a utility
This site is not National Grid, Con Edison, or a government program. It reads public city records and published program rules, and explains what they mean for your building.
No contractor is selected at this stage
Checking an address and verifying an estimate involves no contractor. Introductions happen only if you ask for them after seeing your results.
You decide every step
The estimate is free and anonymous. Verification is free and carries no obligation. Whether anything proceeds beyond that is entirely your call.
Your details are not sold
Contact information is used to review your building and answer your question. It is never sold or shared with anyone you didn't ask to hear from.
How we make money
This site is free for building owners. If — and only if — you ask to move forward after your review, we introduce you to certified installation contractors who participate in the utility programs, including firms affiliated with this site's operators, and the site may be compensated for that introduction. That is the entire model: no fees to owners, no selling of your information, no contractor chosen until you ask.
Check our sources
Every figure on this site traces to a public source, last verified July 2026. Building data comes from NYC PLUTO and DOB Building Footprints; program facts from National Grid, Con Edison, and NYC Accelerator. Questions about the service itself go to the contact page; how data is handled is in the privacy policy.

Frequently asked questions.
Does National Grid pay for insulation in New York?
Yes. National Grid's energy efficiency programs pay for most — on some buildings all — of professional insulation and air sealing for gas-heating customers in its New York service territory: Brooklyn, Staten Island, and southern Queens. The programs are funded by an efficiency charge already collected on gas bills, and the incentive is applied against project cost rather than reimbursed later.
How much is the National Grid insulation rebate?
For multifamily buildings, envelope incentives commonly run $4 to $5 per square foot of insulated roof or attic area — enough to cover most or all of a typical insulation and air sealing scope. Smaller 1–4 unit homes go through National Grid's residential program, which prices incentives as a share of project cost instead. Rates are set per program year and confirmed during an eligibility review.
Which New York City buildings can get National Grid rebates?
National Grid delivers natural gas in Brooklyn, Staten Island, and the southern half of Queens, and buildings with an active National Grid gas account in those areas fall under its energy efficiency programs. Manhattan, the Bronx, and northern Queens are Con Edison gas territory, so those buildings go through Con Edison's comparable programs instead. Con Edison is the electric utility in all five boroughs, which is why the gas account — not the electric one — determines eligibility.
Is NationalGridRebate.com part of National Grid?
No. NationalGridRebate.com is an independent eligibility guide — it is not affiliated with, endorsed by, or operated by National Grid, Con Edison, or any government agency. Official program information is published by National Grid at nationalgridus.com. This site's role is to explain the programs, estimate what a specific building may qualify for from public records, and — only if an owner asks — connect them with certified program specialists for verification.
Do tenants have to move out during insulation work?
No. Roof and attic insulation is blown in from above the top-floor ceiling, through the attic or cockloft, so apartments are not opened up. Wall insulation is injected into existing cavities through small access holes that are patched afterward, which means no demolition and no loss of interior space. Most of the work happens in the attic, the basement, and the exterior.
