A clear, modern breakdown of home EV outlet installation costs in Australia — including 10A, 15A, 32A and 20A/32A three‑phase setups, what affects pricing, and when you can avoid installation entirely with a portable charger.
Key Takeaways
- 10A outlets require no installation — every Australian home already has them.
- 15A outlet installs typically cost $150–$800 depending on wiring and distance.
- 32A single‑phase outlets cost $600–$1,200 and require a dedicated circuit.
- 20A/32A three‑phase outlets cost $1,200–$2,500 depending on supply and switchboard capacity.
- Portable chargers can use any of these outlets, often avoiding installation entirely, if the outlet already exists.

One of the most common questions new EV owners ask is: “How much does it cost to install a home charging outlet?”
Whether you’re considering a 15A upgrade, a 32A single‑phase outlet or a full three‑phase setup, installation costs can vary widely depending on your home’s wiring, switchboard capacity and cable run length.
This guide breaks down typical Australian installation costs for each outlet type — and explains when you can avoid installation altogether by using a portable charger.
Quick Cost Summary (Australia)
| Outlet Type | Typical Cost | Notes |
|---|---|---|
| 10A outlet | $0 | Standard in every home — no installation needed. |
| 15A outlet | $150–$350 (existing wiring) / $400–$800 (new wiring) | Good for moderate charging. |
| 32A single‑phase outlet | $600–$1,200 | Requires a dedicated circuit and licensed electrician. |
| 20A/32A Three‑phase outlet | $1,200–$2,500 | Fastest AC charging — depends on existing supply. |
These ranges cover most Australian homes, but final pricing depends on switchboard capacity, cable run length and installation complexity.
10A Standard Outlet (2.4kW)
Cost: $0
Every Australian home already has 10A outlets. No installation is required.
Best for: light daily driving, overnight charging, renters and apartments.
A portable charger is all you need — no electrician, no upgrades, no extra cost.
15A Outlet (3.3kW)
Cost: $150–$350 if wiring is suitable; $400–$800 if new wiring is required.
A 15A outlet has a larger earth pin and can deliver more stable charging than a standard outlet.
What affects the price:
- Distance from switchboard
- Existing circuit capacity
- Need for new cabling
- Wall type (brick vs plaster)
32A Single‑Phase Outlet (7.2kW)
Cost: $600–$1,200
A 32A outlet requires a dedicated circuit, which is why installation costs are higher.
Best for:
- Faster overnight charging
- Homes with longer daily driving
- EVs with larger batteries
- People wanting wall‑charger speeds without installing a wall charger
What affects the price:
- Switchboard capacity
- Cable run length
- Need for RCD or breaker upgrades
- Installation complexity
20A or 32A Three‑Phase Outlet (11kW–22kW)
Cost: $1,200–$2,500
Three‑phase outlets offer the fastest AC charging available in Australian homes — but only if your EV supports 11kW or 22kW AC charging.
Most homes with three‑phase supply will have either a 20A or 32A 5‑pin outlet. They look almost identical, but the charging speed differs:
-
20A 3‑phase → up to 11kW
-
32A 3‑phase → up to 22kW
Both require a licensed electrician and a dedicated circuit. The main difference is simply how much current the circuit can safely deliver.
What affects the price:
-
Whether your home already has three‑phase supply
-
Switchboard capacity and available space
-
Cable run length
-
Roof access and installation complexity
-
Need for RCD or breaker upgrades
If your home already has three‑phase supply, installing a 20A or 32A outlet is usually straightforward. If you don’t have three‑phase, upgrading can cost significantly more depending on your electricity provider and the distance from the street to your switchboard.
When a 20A outlet is enough
If your home already has a 20A 3‑phase outlet, you can still charge at up to 11kW with a compatible portable charger — no need to upgrade to 32A unless you specifically want the full 22kW capability.
When You Don’t Need Installation at All
Portable chargers can plug into:
- 10A outlets (standard)
- 15A outlets
- 32A outlets
- 20A or 32A Three‑phase outlets (with the correct plug type)
This means many homes can avoid installation entirely if a suitable outlet already exists.
Portable chargers offer:
- 6A–32A adjustability
- Smart scheduling
- Solar‑aware charging
- App control
- IP66+ weather ratings
- RCM compliance (when purchased from reputable Australian suppliers)
What Affects Installation Cost?
Electricians price installations based on:
- Distance from switchboard
- Cable run length
- Roof access difficulty
- Wall type (brick, block, plaster)
- Switchboard capacity
- Need for RCD or breaker upgrades
- Whether three‑phase supply already exists
Which Setup Should You Choose?
Choose 10A if: you drive short distances and charge overnight.
Choose 15A if: you want faster charging without major installation costs.
Choose 32A if: you want the best balance of speed, cost and flexibility.
Choose 20A/32A three‑phase if: your home already has three‑phase and your EV supports 11–22kW AC charging.
Final Thoughts
Understanding installation costs makes it much easier to choose the right home charging setup. For many Australian homes, a portable charger paired with an existing 10A, 15A, 20A or 32A outlet is the simplest and most cost‑effective solution.
