Included in this price
- The charger: Supplied new, with the maker's residential warranty in your name.
- Mounting: Fixed to a suitable wall in the spot agreed from your photos: timber-framed, weathertight, ground floor.
- A dedicated circuit: Its own circuit and protection device in your existing switchboard, sized for the charger.
- The cable run: Surface-mounted cable from the switchboard to the charger, up to the length set in your quote.
- Testing and commissioning: The electrician tests the installation and sets the charger up on your phone.
- The Certificate of Compliance: Issued by the registered electrician who did the work, and emailed to you. Your balance is only due after this.
Priced separately, in your quote
- Switchboard work: An older board with no spare capacity, ceramic fuses or no RCD protection needs work before a charger goes on it.
- Extra cable: Anything past the cable length in your quote, priced per metre.
- Brick, block or concrete wall: Harder to fix to and to run cable through than timber framing.
- Trenching: For a detached garage or carport where the cable has to go underground.
- A new or upgraded supply: Going to three phase, or lifting your amperage, involves your lines company and is quoted separately.
Never charged unless it was named and priced before you paid.

Questions about the X22
How much is an X22 installed in New Zealand?
We haven't published ours yet: it needs our installer's written trade price, and we won't post a number we can't honour. For reference, Evnex sells the X22 installed direct for $3,374 as a base estimate, and the published New Zealand range for this kind of job is $2,500 to $5,000. Send your photos and we'll email your fixed price as soon as it's set.
Will the X22 work with my car?
It has a tethered Type 2 connector, which is the standard AC connector on essentially every EV and plug-in hybrid sold new in New Zealand. The thing to check is whether your car's onboard AC charger can actually accept more than 7kW: many can't, in which case a 7.4kW charger charges it just as fast for less money.
Do I need three phase for this?
Yes. The X22 needs a three-phase supply and won't work on a single-phase one. If you don't already have three phase, getting it is a lines-company job with its own fee and lead time, quoted separately. How to tell which you have.
What if my switchboard needs work?
It's priced in the same quote as a named line, not discovered on the day. The published New Zealand range for switchboard work is $1,500 to $3,000, and a photo of your board with the door open tells us in seconds whether you need it. More on switchboards.
Who installs it, and do I get a certificate?
A registered electrician from our partner installer does all the electrical work, tests it and issues the Certificate of Compliance in their own name. We quote the job and hold the contract with you. We are not electricians. What the certificate is.
When do I pay?
A $500 deposit when you accept the price, fully refundable any time before installation starts. The balance is invoiced only after the Certificate of Compliance is issued.
Send your photos. Get one price.
Five phone photos and five minutes. We check them with our installer and email one fixed price for the charger, the install and the Certificate of Compliance. Nothing is charged until you accept it.
