Keep one folder — paper, digital or both — with six things: the permit and inspection record, the electrician’s invoice, the charger receipt, a photo of the nameplate with the serial number, photos of the finished installation, and the warranty details. How long you keep each piece depends on what it protects, and the sections below tie the timing to events (a warranty claim, a house sale, a question from your insurer or tax adviser) rather than to made-up deadlines.
Key Takeaways
- One folder: permit and inspection record, electrician’s invoice, charger receipt, nameplate photo, installation photos, warranty terms.
- Keep warranty papers past the warranty’s end, permit records while you own the home, and photos indefinitely.
- Scan everything the week the job is finished and store a copy with your property documents.
- For anything tax-related in the file, your tax adviser — not a rule of thumb — sets the retention period.
The Installation File, Item by Item
| Document | Why you keep it | When you will need it |
|---|---|---|
| Permit and inspection sign-off | Proves the circuit was approved by your local authority. | Insurer questions, house sale, any later electrical work on the same panel. |
| Electrician’s invoice | Shows who did the work, the circuit size and the date. | Warranty disputes about installation, insurer questions, future upgrades. |
| Charger receipt and order confirmation | Proves purchase date and price — the start of the warranty clock. | Warranty claims and any credit or deduction paperwork. |
| Nameplate photo (model and serial) | Identifies the exact unit without taking it off the wall. | Warranty claims, recall checks, manufacturer support calls. |
| Photos of the installation and panel schedule | Shows how and where it was installed, and which breaker feeds it. | Troubleshooting, upgrades, a buyer asking what they are inheriting. |
| Warranty card or terms | States what is covered and for how long. | The day something stops working. |

How Long to Keep Each Piece
There is no single retention rule for a home charger file, so keep documents for as long as the thing they protect:
- Warranty documents: at least until the warranty expires. EVDANCE’s standard warranty is 3 years; other brands differ, and our comparison of EV charger warranties shows the range.
- Permit and inspection records: for as long as you own the home. They describe wiring that stays in the walls, and a buyer’s inspector may ask about them years later.
- Receipts and invoices: as long as any tax, insurance or resale question about the installation could still be open. Your tax adviser can tell you what that means for a credit or deduction you claimed — see our overview of whether charger installation is tax deductible.
- Photos: indefinitely. They cost nothing to store and answer questions no document can.
Digital Copies, Stored Where You Will Find Them
Paper folders get lost in moves and clean-outs. Scan or photograph every document the week the installation is finished, and store the set in two places: a cloud folder named for the house, and a copy alongside your other property documents. Export your charger app’s session history once in a while as well — app accounts change when you replace a phone or a charger, and the history is part of the file. If you sell the house, this folder becomes the handover pack, which supports the points in our article on EV chargers and home value.
Equipment That Keeps Its Own Records
A smart wallbox keeps dated session records you can export, which is one less thing to reconstruct by hand. The EV-ACT3204PE is a 22 kW three-phase wallbox with RFID and app control, so session history, user access and the unit’s identity are all in one place. Whatever you install, photograph the nameplate before the first charge — that photo anchors the whole file.
Frequently Asked Questions
My installer did not leave me a permit copy. How do I get one?
Ask the installer first — they filed it. If that fails, your local permitting office can usually provide the record for your address. File whatever you receive with the invoice.
Do I really need a photo of the nameplate?
Yes. Model and serial number are what warranty and recall checks run on, and the nameplate is awkward to read once the unit is mounted. One clear photo solves it permanently.
I bought a house with a charger already installed. What should I do?
Build the file from what exists: photograph the nameplate and installation, note the breaker that feeds it, and ask the seller or their agent for any permit or invoice copies. Anything missing is worth a line in an electrician’s inspection visit.
