Insulation Rebates and Incentives in 2026: What Virginia, Maryland & DC Homeowners Can Still Check For

If you last read about a 30 percent federal insulation tax credit and are planning work for 2026, the important update is this: that credit ended. The Energy Efficient Home Improvement Credit, Section 25C of the tax code, applied only to qualifying property placed in service before December 31, 2025. Insulation installed in 2026 does not qualify, and a contractor who tells you otherwise is working from out-of-date information.

That does not mean incentives have disappeared. Utility rebate programs from Dominion Energy, Pepco and BGE have their own rules and funding, and some homeowners may qualify for income-based programs. This guide explains what changed, what to check before you sign a contract, and what a realistic project cost looks like without the federal credit.

Section 01What Happened to the Federal 25C Credit

From 2023 through 2025, Section 25C gave homeowners a credit worth 30 percent of the material cost of qualifying insulation, up to an annual limit, for existing principal residences. The IRS states that the credit is allowed for qualifying property placed in service on or after January 1, 2023, and before December 31, 2025.

In practical terms: if insulation goes in during 2026, there is no federal credit to claim for it. Older articles, including earlier versions of this one, said the credit ran through 2032. That was wrong for current work, and we have corrected it here and across our site.

For the current rules, check the IRS page on the Energy Efficient Home Improvement Credit or ask your tax professional. We are not tax advisors, and this page is general information.

Section 02If Your Work Was Completed in 2025

Homeowners whose insulation was installed and paid for during 2025 fall in the last year of the credit and may still claim it on the 2025 federal return using IRS Form 5695. Keep the itemized invoice, proof of payment, and the manufacturer certification statement for the product.

The credit is non-refundable, so it can only reduce tax you owe. If your liability is small, you may not be able to use the full amount. A tax professional can confirm how it applies to your return.

Section 03Dominion Energy Rebates (Virginia)

Dominion Energy has operated residential energy efficiency programs in Virginia, funded through a rider on electric bills, that include rebates for measures such as insulation, duct sealing and smart thermostats.

Eligibility: The home must be served by Dominion Energy for electric service. Customers of Northern Virginia Electric Cooperative (NOVEC) or other electric utilities are not eligible for Dominion rebates but may have separate cooperative programs.

Insulation rebates: Amounts for insulation work have typically ranged from $300 to $1,500 depending on scope, home type and program rules in effect. Attic, wall, basement and crawl space insulation and air sealing may qualify under different sub-programs. Treat these as historical ranges and confirm the current figure before you commit.

Approved contractor requirement: Most Dominion insulation rebates require the work to be performed by a contractor on Dominion's approved list, and we file rebate paperwork on behalf of homeowners where the program allows it.

Pre and post documentation: Some programs require a pre-installation home energy assessment and a post-installation verification.

For more on the kind of work these programs cover, see our Virginia insulation energy efficiency guide.

Section 04Pepco and BGE Rebates (Maryland and DC)

Maryland and DC homeowners are served primarily by Pepco (DC, Montgomery and Prince George's counties) and BGE (the Baltimore-Washington corridor, Anne Arundel, Howard and parts of Prince George's). Maryland insulation rebates run under the EmPOWER Maryland framework overseen by the Maryland Public Service Commission.

Structure: Historically these programs have paid a per-square-foot rebate for qualifying attic insulation and separate amounts for air sealing and duct sealing, with annual program caps. Dollar amounts are reset by program year, so ask for the current schedule.

Pre-approval and contractor: Most rebates require approval through the utility before work begins and use of an approved contractor.

Audits: Some utility programs include a discounted or free home energy assessment that can identify additional qualifying measures.

Section 05Other Programs to Ask About

Income-qualified households should ask whether any state-administered home energy rebate or weatherization program is currently open. The Virginia Department of Energy and the Maryland Energy Administration are the places to check. Availability, income limits and timing change, so we do not list figures here.

Historic-home owners and HOA members should also confirm any local approval steps before work starts. Those are permit or design-review issues, not incentives, but they affect timing.

Section 06The Math Without the Federal Credit

Here is an illustrative whole-house spray foam project with no federal credit in the picture:

Project cost: $14,000.

Utility rebate (if eligible): $750, a mid-range figure for a multi-measure project. Your actual rebate may be higher, lower or zero.

Net cost: $14,000 - $750 = $13,250.

Annual energy savings: $1,400, typical for a complete envelope retrofit on a 2,400 square foot home. Actual savings depend on the home, its starting condition and energy prices.

Simple payback: $13,250 / $1,400 = about 9.5 years. Closed-cell spray foam has a long service life, and comfort, moisture control and resale appeal add value that a payback figure does not capture.

Smaller, targeted projects such as an attic top-up plus air sealing often pay back faster than a whole-house retrofit, because they capture the biggest losses first.

Section 07What Utility Rebates Typically Cover

"Often" and "Sometimes" reflect how these programs have generally worked. The utility's current program sheet is the authority on what your project qualifies for.

Section 08Program Risk and Timing

The federal credit's end is a reminder that incentives are not permanent. Utility rebate programs are funded through state regulatory processes, reviewed periodically, and can change in amount and scope from one program year to the next.

If a rebate matters to your decision, get its current terms in writing, confirm whether pre-approval is required, and do not start work before approval if the program requires it. A rebate that you have to gamble on is not a reason to rush a project that is otherwise sound.

Section 09Practical Steps

Step 1: Get a walk-through quote from a contractor who will tell you plainly which incentives are still current.

Step 2: Ask the utility (or the contractor filing for you) whether your project needs pre-approval, and get that before work begins.

Step 3: Confirm the rebate amount and deadline in writing.

Step 4: Get an itemized invoice with square footage, R-values and product names.

Step 5: Keep proof of payment and photos of the finished work with your home records.

Step 6: File the rebate application within the utility's post-installation window.

Section 10Rebate Paperwork Mistakes

Rebate programs reward homeowners who document their work correctly and penalize sloppy paperwork. These are the mistakes we see most often.

Starting before pre-approval

Some programs will not pay for work that began before the utility approved it. Ask before the crew arrives.

Using a lump-sum invoice

Rebate reviewers want scope, square footage and R-values. An itemized invoice makes the application clean. We itemize every project.

Missing the filing window

Utilities generally have strict post-installation filing windows, often 60 to 90 days. Miss the window and the rebate can be lost, so note the deadline the day the job finishes.

Section 11Get Started

Most projects start with a fifteen-minute phone consultation. We will quote the work, tell you which rebates look current for your utility and address, and lay out the paperwork you would need.
