EV charger installation cost is not one number, because no two homes present the electrician with the same job. The charger itself is usually the smallest variable. What moves the figure is the distance from the switchboard to the parking space, the spare capacity in that switchboard, and whether the property runs on single phase or three phase power. Clean Earth Solar quotes every EV charger installation after looking at those three things, because a quote given over the phone without them is a guess.
What Are You Actually Paying For in an EV Charger Installation?
Four things sit behind every quote: the charger unit, the cabling and containment between the switchboard and the charger, any switchboard work needed to supply it safely, and the electrical testing and paperwork that make the install compliant. Homeowners tend to price the first item and forget the other three.
- The charger: A wall-mounted unit, either a plain 7kW single-phase charger or a smart charger that talks to your solar and your phone.
- The cable run: The length, the route, and whether it can be surface-mounted or has to go through a wall cavity, a ceiling, or underground to a detached garage.
- The switchboard: A dedicated circuit, its own breaker, and the correct RCD protection. Older boards often have no spare space to give.
- Compliance: Testing, a certificate of compliance, and where required, notifying the network operator that a new load has been added.
A short run onto a garage wall directly behind the switchboard is a straightforward day’s work. The same charger, thirty metres away at the end of a rural Hawkesbury driveway, is a different job entirely.
7kW Single Phase or 22kW Three Phase?
For most households a 7kW single-phase charger is the right answer. It adds roughly 40 kilometres of range per hour of charging, which fills almost any EV overnight on an off-peak window.
When a 7kW Charger Is Enough
If the car sits at home from six in the evening until seven the next morning, 7kW covers a daily commute several times over. Most Australian homes are single phase, so this option also avoids any supply upgrade.
When Three Phase Is Worth It
Three-phase 11kW or 22kW charging suits households with two EVs, high daily kilometres, or a vehicle that only takes a fast charge on three phase. The catch is that the vehicle’s onboard charger sets the ceiling, many EVs cap at 11kW even when plugged into a 22kW unit, so the extra capacity does nothing.
If the property already has three-phase supply, stepping up is mostly a matter of cabling and a larger breaker. If it does not, bringing three phase to the property is a network job with its own timeline and cost, and it rarely pays for itself on charging alone.
How Cable Run and Switchboard Capacity Change the Price
Distance and switchboard condition are the two biggest swing factors in any home EV charger installation. They are also the two things a homeowner can check before the electrician arrives.
Cable Run Distance
Cable is sized to the load and the length. A long run needs a larger conductor to keep voltage drop inside the limits set by the wiring rules, so a 25-metre run to a detached shed costs more than double a 10-metre run, the cable is both longer and thicker. Routing matters too: a surface-mounted conduit along a garage wall is quick, while trenching across a driveway is excavation work.
Switchboard Capacity and Age
An EV charger needs its own dedicated circuit with RCD protection. Boards installed before the 2000s frequently have no spare ways, rewireable ceramic fuses, or no main switch arrangement that suits a new high-continuous load. In those cases a switchboard upgrade is part of the job, not an upsell.
Where the existing supply is already close to its limit, dynamic load management is often the cheaper path. A load-managing charger monitors the whole-of-house draw and throttles the car back when the oven, air conditioner and hot water are all running, which can avoid a service upgrade altogether.
What Does a Compliant EV Charger Installation Look Like?
A compliant install is a dedicated circuit, correctly sized cable, RCD protection suited to the charger’s DC leakage characteristics, secure mounting at a sensible height, and a certificate of electrical safety issued at the end. Every Clean Earth Solar install is carried out by SAA-accredited electricians, the company employs electricians and electrical apprentices only, with no subcontracted labour on any job.
The rules governing this work sit in the AS/NZS 3000 wiring standard published by Standards Australia, alongside the manufacturer’s installation instructions for the specific charger. Anything installed outside those, a caravan socket pressed into service, an extension lead through a window, an unprotected circuit, is a fire risk and a warranty problem.
- Dedicated circuit and breaker, not a shared or borrowed one
- RCD protection appropriate to the charger type
- Cable sized for the load, the run length and the installation method
- Certificate of compliance and network notification where required
Asking for the compliance certificate before final payment is the simplest quality check a homeowner has.
Can You Charge an EV From Your Solar System?
Yes, and it is the reason a lot of Hawkesbury households install both. A smart charger can be set to draw only surplus solar, the energy that would otherwise be exported for a small feed-in credit — and step the charging rate up and down as production changes through the day. Households with a solar battery can extend that into the evening rather than charging from the grid after dark. Our comparison of home vs public charging cost per kilometre shows how much that shift is worth over a year of driving.
Getting the sizing right matters here. An EV can easily add more annual consumption than a hot water system, so a solar system designed before the car arrived is often undersized once it does. Reading past bills alongside expected charging kilometres is the honest way to work out whether the array needs expanding, and the difference between kW and kWh is worth understanding before that conversation.
For homes running solar, battery and EV charging together, a hybrid solar system keeps all three on one platform, and real-time monitoring shows exactly how much of the car’s charge came from the roof rather than the grid.
Getting an Accurate Quote
An accurate quote needs a look at the switchboard, the intended charger position, and the path between the two. Photographs of the switchboard and the parking space usually get a homeowner most of the way there, with a site visit confirming the run. Clean Earth Solar quotes are fixed before work starts, and the consultation is with an installer rather than a salesperson.

Frequently Asked Questions
How much does it cost to install an EV charger at home?
There is no standard figure, because the price follows the property rather than the charger. Contact Clean Earth Solar directly for an accurate quote — all pricing is confirmed before any work begins, with no obligation to proceed.
Why is level 2 EV charger installation cost higher on some homes?
Level 2 EV charger installation cost rises when the cable run is long, when the switchboard needs upgrading to take a dedicated circuit, or when the route involves trenching or a wall cavity. Two identical chargers on two neighbouring houses can quote very differently for exactly those reasons.
Do I need a switchboard upgrade for an EV charger?
Only if the existing board has no spare capacity, lacks suitable RCD protection, or is too old to safely take a continuous high load. An electrician can tell from a photo of the board whether it is likely, and confirms it on site.
What are the EV charger installation requirements in Australia?
Home chargers must be installed by a licensed electrician on a dedicated, RCD-protected circuit sized to AS/NZS 3000 and to the manufacturer’s instructions, with a certificate of compliance issued afterwards. Some network operators also require notification that a new load has been connected.
Can I install an EV charger myself?
No. Hard-wired EV charger installation is licensed electrical work in every Australian state and territory, and a non-compliant install voids both the charger warranty and, potentially, home insurance cover.
How long does a home EV charger installation take?
A straightforward install near the switchboard is usually finished in a day. Jobs involving a switchboard upgrade, a long underground run or a three-phase supply change take longer and are scheduled accordingly.
