Insulation Rebates

Where to look

• United States: ENERGY STAR keeps a page on federal tax credits for home improvements, and states and utilities run their own programs. Start at ENERGY STAR and follow links to current tax credit pages, and check your state energy office and electric or gas utility.
• Canada: Natural Resources Canada lists federal programs and links to provincial and territorial ones. Utilities and some municipalities run their own.

We deliberately do not name programs, amounts or deadlines because they change and we cannot keep them current.

Common requirements

Programs often require one or more of:

• A pre-retrofit energy assessment by a registered or certified advisor.
• A post-retrofit assessment to confirm work.
• Work completed after the program's start date and before its deadline.
• Approved products, sometimes with specific R-value levels.
• Installation by a qualified contractor, or rules for DIY.
• Original receipts, product labels or bag counts, and photos.
• Applying before work starts.

Avoiding scams

• Real programs are listed on government or utility websites; verify any phone or door-to-door offer independently.
• Be wary of anyone guaranteeing a rebate amount or asking for upfront fees to "secure" funding.
• Do not share personal financial details with unverified callers.
• Read contracts carefully; some sellers bundle financing with high interest.

Tax credits

Tax credits reduce income tax rather than paying you cash at purchase. Eligibility depends on your tax situation and on program rules. Talk to a tax professional and keep records.

Planning around incentives

1. Find current programs and read the rules.
2. Book any required assessment before work.
3. Get quotes that match the program's requirements.
4. Do the work and keep documentation.
5. Book any post-assessment and submit claims promptly.

Use the cost calculator without incentives first, so the project makes sense even if a program changes.

Worked example

Figures below are illustrative examples (2026-10-29), not quotes or guarantees.

Assumptions: a project estimated at $2,690 before incentives (from the attic insulation cost example). If an official program you find covers a portion, subtract that amount only after confirming eligibility in writing. We show no rebate figure here because any number we picked would be invented.

Vermiculite and incentives

Some programs exclude homes with vermiculite until it is professionally assessed or removed. If you suspect vermiculite, do not disturb it, and ask the program what it requires.

Keeping records that programs ask for

• Dated photos before and after, including depth markers.
• Invoices showing product, R-value and area.
• Bag counts or labels.
• Assessment reports.
• Contractor details.

Store them digitally and on paper until the claim is paid and any audit period has passed.

Utility programs

Many electric and gas utilities run efficiency programs, sometimes including insulation rebates, free assessments, or discounted contractor networks. Check your utility's website or bill inserts, and confirm the program is current.

Low-income and community programs

Some governments and non-profits offer free or low-cost weatherization for eligible households. Eligibility usually depends on income and location. Contact your local or regional energy office.

Combining programs

Some programs can be stacked; others cannot. Read the rules, because claiming two incompatible incentives can lead to clawbacks.

When a program ends mid-project

Programs can close or change with little notice. Apply as early as allowed, keep confirmations, and budget so the project still works without the incentive.

Our policy

We link only to official government and recognised agency pages. We do not publish amounts, accept payment from programs, or promise eligibility.

How to verify a program is real

Scams can mimic rebate programs. Verify by going directly to official government or utility websites, not links in unsolicited emails or calls. Real programs do not ask for payment to apply. Be wary of contractors who claim a program pays for everything or pressure you to sign on the spot. If unsure, call the program's official phone number listed on its website. Never share banking details with an unverified caller. In Canada, start from Natural Resources Canada pages; in the U.S., start from ENERGY STAR and your state energy office. Keep a note of the date and source of each piece of program information you rely on, because programs change. If a contractor says a step is required by a program, ask them to show you where the rule is written in official program materials before you agree.

Tax credits

In some places, efficiency upgrades may qualify for tax credits rather than rebates. Rules, limits and documentation differ; check official tax authority guidance or ask a tax professional. We do not give tax advice or amounts.

Before you sign a contract

Ask the contractor whether they are registered with any program you plan to use, whether they will provide documents the program needs, and who files the claim. Confirm in writing. Do not assume a contractor's statement about eligibility is correct; check with the program directly.

Bottom line

Check official sources, follow program steps in order, keep records, and treat any incentive as a bonus rather than a guarantee.

Quick checklist

1. Find current programs on official sites.
2. Read eligibility and required steps.
3. Book any required assessment before work.
4. Use eligible contractors and products if required.
5. Keep photos, invoices and labels.
6. Submit the claim before the deadline and save confirmations.

Programs change frequently, and some have limited funding, so check again just before you start work rather than relying on what you read months earlier.

Never pay a fee to apply.
