A home EV charger in Australia costs between $1,200 and $3,000 fully installed, depending on the charger type and how much electrical work your house needs.
That range covers a standard 7kW single-phase wall charger on a house with a modern switchboard and a short cable run. Add a switchboard upgrade, a long cable route, or a three-phase 22kW unit and the EV charger installation cost climbs from there.
This article breaks down where the money goes, what pushes the price up, and how to keep costs reasonable. If you are on the Mid North Coast and want a quote from a local CEC-accredited installer, contact SolaXs for a site assessment.
If you already have solar panels, adding an EV charger to your existing system can mean charging your car with power you are already generating. SolaXs installs EV chargers alongside solar and battery systems on the Mid North Coast.
EV Charger Installation Cost Breakdown
The total cost splits into two parts: the charger unit itself and the electrical installation. The charger hardware ranges from $600 for a basic untethered unit to $2,000+ for a smart charger with load management, an integrated cable, and an app. Installation labour and materials add $500 to $1,500 depending on your switchboard condition and the distance between the meter board and the charging location.
| Component | Typical Cost Range |
|---|---|
| Charger unit (7kW single-phase) | $600 – $1,800 |
| Charger unit (22kW three-phase) | $1,500 – $3,500 |
| Dedicated circuit and RCD | $300 – $600 |
| Standard installation labour (1-2 hours) | $200 – $500 |
| Switchboard upgrade (if required) | $500 – $1,500 |
| Extended cable run (20m+) | $300 – $800 |
| Three-phase supply upgrade | $1,000 – $3,000 |
A straightforward install on a house with a modern switchboard, single-phase supply, and the meter board near the garage typically lands at $1,200 to $1,800 all up. That is the sweet spot most homeowners hit.
What Affects Your EV Charger Installation Cost
Every house is different, which is why quoting over the phone without seeing the property is unreliable. The factors below are what electricians assess during a site visit, and each one can shift your total by hundreds of dollars.
- Switchboard condition: older switchboards without spare capacity need an upgrade before they can handle a dedicated 32A circuit. This is the most common surprise cost.
- Cable run distance: the further the cable travels from the switchboard to the charger location, the more cable and labour required. Runs over 20 metres add meaningful cost.
- Single-phase vs three-phase: a 7kW single-phase charger suits most households. A 22kW three-phase unit charges roughly three times faster but requires three-phase supply at the property.
- Charger brand and features: basic units with no connectivity are cheapest. Smart chargers with load management, solar integration, and scheduled charging cost more but save money over time.
- Mounting surface: brick and concrete walls are straightforward. Weatherboard, rendered foam, or corrugated steel may need additional mounting hardware.
- Existing solar system: if you already have solar, a charger with solar integration can prioritise charging during peak generation hours, reducing grid draw.
The single biggest cost variable is the switchboard. If your home was built before the mid-2000s, budget an extra $500-$1,500 for switchboard work.
Single-Phase vs Three-Phase EV Charger Costs
Most Australian homes have single-phase power, which supports a maximum 7kW EV charger. A 7kW charger adds roughly 40-45km of range per hour of charging. For a typical daily commute of 40-60km, overnight charging on single-phase covers it easily.
Three-phase power supports 22kW chargers, adding around 120-130km of range per hour. Three-phase is standard in newer homes and some rural properties, but older suburban homes usually need a supply upgrade from the distributor.
| Factor | Single-Phase 7kW | Three-Phase 22kW |
|---|---|---|
| Charger unit cost | $600 – $1,800 | $1,500 – $3,500 |
| Installation cost | $500 – $1,000 | $800 – $1,500 |
| Supply upgrade needed? | Rarely | Often (if not already 3-phase) |
| Charge speed | ~40km range/hour | ~130km range/hour |
| Typical total installed | $1,200 – $2,500 | $2,500 – $5,000+ |
| Best for | Daily commuters, overnight charging | High-mileage drivers, fast turnaround |
Our opinion: unless you are driving 150+ km daily or running a business vehicle, single-phase 7kW is more than enough. The money saved on a three-phase upgrade is better spent on solar panels to offset your charging costs.
Hidden Costs to Watch For
The quote you receive should be fully itemised. If it is a single lump sum with no breakdown, ask for one. Here are the costs that catch people off guard.
- Metering board relocation: in some older homes, the meter board is inside the house or in an awkward location. Moving it is a separate job and a separate cost.
- Trenching for underground cable: if the charger is in a detached garage or carport, the cable may need to run underground. Trenching adds $50-$100 per metre.
- Network approval: chargers above 5kW on some networks require approval from the local distributor (Ausgrid, Essential Energy, Endeavour). The approval is free but can delay the install.
- Load management devices: if your switchboard is at capacity, a load management device can prevent the charger from overloading the supply. This avoids a full switchboard upgrade but adds $200-$400.
On the Mid North Coast (Essential Energy network), chargers over 5kW may require a connection agreement. Your installer should handle this paperwork. SolaXs manages the full process including network approvals for all EV charger installations.
Can You Use a Regular Power Point Instead
Technically, yes. Every EV comes with a portable charger (often called a granny charger) that plugs into a standard 10A power point. It charges at roughly 2.3kW, adding about 10-12km of range per hour. For a 60kWh battery, a full charge from empty takes over 24 hours.
The maths works if you have a short commute and charge every night. But there are practical problems with relying on a power point long-term.
- Standard power points are not designed for sustained high loads over 8+ hours
- Heat builds up in the plug and socket over time, increasing fire risk
- No safety features like residual current protection or temperature monitoring
- Many Australian strata and body corporate rules prohibit EV charging from general power outlets in shared garages
A dedicated EV charger on its own circuit with an RCD is the safe, permanent solution. The Energy Safe Victoria guidelines recommend dedicated circuits for any sustained high-load appliance, and EV charging falls squarely in that category.
How Solar Panels Reduce Your Charging Costs
Charging an EV from the grid costs roughly $15-$20 per 100km at current NSW electricity rates (around 30-35c/kWh). Charging from your own solar panels costs effectively nothing once the system is paid off. Even before payoff, solar-generated power costs roughly 5-8c/kWh when you factor in the system cost over its lifetime.
A 6.6kW solar system on the Mid North Coast generates around 25-30kWh on a good day. A typical EV uses 15-20kWh per 100km. That means a single day of solar generation covers 120-200km of driving, well beyond most daily commutes.
- Charge during the day when solar production peaks (if you work from home or have flexible charging)
- Use a smart charger with solar diversion to automatically charge only when excess solar is available
- Add a home battery to store daytime solar for overnight charging
- Time your charging to avoid peak grid rates (typically 2pm-8pm)
SolaXs installs EV chargers alongside solar and battery systems, so the whole setup is designed to work together from day one. Get in touch for a combined solar and EV charger quote on the Mid North Coast.
How to Get the Best Price on Installation
The cheapest EV charger installation is not always the best value. A poor install with undersized cable, no load management, or a charger mounted in direct sun will cost more in the long run. Here is how to get a fair price without cutting corners.
- Get 2-3 quotes: compare itemised quotes, not lump sums. Make sure each quote includes the same scope.
- Choose a CEC-accredited installer: the Clean Energy Council accreditation means the electrician has specific training in EV charger and solar installations.
- Bundle with solar: if you are getting solar panels or a battery at the same time, the installation cost for the EV charger drops because the electrician is already on site and the switchboard work overlaps.
- Check for rebates: some state governments and local councils offer EV charger rebates or incentives. The Australian Government energy website lists current programs.
- Pick the right charger size: do not pay for a 22kW three-phase charger if 7kW single-phase covers your needs.
