Loss of Invoice or Documents After the Work: Key Steps to Recovering Your LogisVert Grant

When you carry out energy efficiency work, such as installing a heat pump or insulating a roof, you naturally expect to receive the promised grant. But what happens if, after the work is completed, you lose an invoice or a document essential to your LogisVert Grant file? At AirGreen , we have helped many clients in Montreal, Laval, Longueuil, on the North Shore and the South Shore who have found themselves in this stressful situation. Here is our complete guide to help you find your documents and save your financial assistance.

The Critical Importance of Documents in the LogisVert Program

Hydro-Québec's LogisVert program imposes strict requirements regarding the documents that must be provided. Without these requirements, even if the work was carried out according to regulations, your application could be rejected.

Essential documents required for the heat pump:

• Proof of purchase : detailed invoice with customer name, installation address, company name, RBQ number, GST/QST, product description, cost.

• Photo of the exterior nameplate (serial number and model).

• Proof of ownership : municipal tax bill or deed of sale.

Without these elements, no grant will be paid , even if the installed system appears on Hydro-Québec's list of eligible heat pumps.

Step 1: React Quickly – The 9 Month Timeframe

Once the work is completed, you have a maximum of 9 months to submit your application on the official portal www.logisvert.ca . If you lose a document, the countdown continues.

At AirGreen, we recommend that all our clients gather their documents immediately after the work and keep them in digital format (PDF, photo, etc.). If you have exceeded this 9-month deadline, even the best evidence will not be able to reopen your file.

Step 2: Contact the Installer – First Reflex

If you have lost an invoice (often the most critical), your first instinct should be to contact the installation company .

At AirGreen , we keep a secure archive of all our installations, including:

• Official invoices with all required details (RBQ, GST/QST, AHRI, BTU at -8 °C, etc.)

• Photos taken on site

• Proof of receipt of payment

• Exact coordinates of the installation

We can usually reissue a compliant invoice within 24 to 72 hours , even if the work was done several months earlier. If you used another contractor, contact them immediately. Insist on a detailed invoice that includes all the information requested by Hydro-Québec.

Step 3: Find Your Proof of Payment

If you can't find the invoice, but you paid by credit card or bank transfer, your bank statement can be used as additional proof . It doesn't replace the official invoice, but it can help convince the installer to create a duplicate.

Make sure that:

• The company name appears on the payment line

• The amount corresponds to the signed submission or estimate

• The date is well within the admissible period

Step 4: Find the Missing Photo

Hydro-Québec requires a clear photo of the outdoor compressor's nameplate . If you have lost it:

• Go back to the spot and take another photo.

• Check your phone or email (installers often send these photos with the final report).

• Contact AirGreen if we carried out the installation: we systematically take these photos and keep them in our archives.

Step 5: Gather Related Documents

Here is a verified list of other documents you may need to locate:

• Proof of ownership: municipal tax bill or deed of sale.

• Invoice for the roof insulation and air sealing (if this measure is combined in the application).

• NEQ, NAS or GST/QST number (for Relevé 27 required for reimbursements).

• Overall photo of the indoor unit (in some cases requested during the conformity check).

What to Avoid at All Costs

Don't wait until the last minute. An incomplete file or a missing invoice can delay processing for additional weeks (sometimes 12 weeks or more).

Never submit a false bill or an erroneous declaration. Hydro-Québec reserves the right to:

• Decline your request.

• Demand a full refund .

• Prohibit any future access to the Program.

Good to Know: Possible Financial Bonus

If you have carried out several measures (e.g. heat pump + roof insulation with air sealing, or heat pump + heat pump dryer) within the same 9-month period, you can receive a 5% bonus on the total amount. But each measure requires its own set of documents. Losing one of them can wipe out the whole bonus.
