What's Included in the Price
- Supply and install of a Level 2 (7kW) wall-mounted charger
- Dedicated circuit from the switchboard with RCD protection to AS/NZS 3000 Wiring Rules
- Cable sized to AS/NZS 3008 for continuous load rating
- Cable run, conduit, and weatherproofing
- Testing, commissioning, and Electrical Safety Certificate
In Brisbane, outdoor and carport installs are more common than in southern cities, which means weatherproofing is often a standard part of the job rather than an add-on.
What Affects the Cost
- Carport vs garage mounting. Carport installs need weatherproof enclosures and UV-rated components, adding to material costs compared to an enclosed garage. For carport installs, look for IP65 minimum. Fully exposed locations in subtropical weather — no roof cover at all — should use IP66-rated units.
- Cable run length. Queenslanders with the switchboard under the house and the car parked in a separate carport can mean longer runs. Sub-floor routing is often straightforward, but detached carports add distance.
- Switchboard capacity. If your board is already handling solar, split system air conditioning, and a pool pump, you may need a switchboard upgrade to fit the charger circuit.
- Dynamic load balancing (DLB). Especially relevant in QLD homes already running solar, pool pump, and aircon simultaneously. DLB uses CT clamps at the switchboard to monitor total consumption and automatically throttles the charger when other loads spike. This can avoid a switchboard upgrade entirely — a significant saving.
- Heat management. Chargers in direct sun need shading or heat-rated enclosures to maintain efficiency and longevity. West-facing walls are the worst offenders.
- Solar integration. With Queensland's high solar penetration, smart chargers that prioritise solar power are a popular and worthwhile upgrade. Smart chargers like the Zappi offer "Eco" and "Eco+" modes — Eco+ only charges from surplus solar, while Eco tops up from the grid if solar isn't enough. Fronius Wattpilot integrates natively with Fronius inverters for seamless solar charging.
- Charger unit selection. The charger itself ranges from roughly $750 to $1,800 before installation, depending on brand and features. Popular units in Australia include Fronius Wattpilot, Zappi, ABB Terra, and Wallbox Pulsar Plus.
- Single vs three phase. Three-phase supply is less common in older Brisbane homes but allows faster 22kW charging.
A straightforward install on a shaded garage wall with the switchboard nearby, no board upgrade needed, and single-phase supply sits toward $1,350. A detached carport 20 metres from the house, a full switchboard requiring upgrade, three-phase wiring, and extensive weatherproofing pushes toward $3,150.
Brisbane-Specific Considerations
Queenslander-style homes present a unique setup for EV charging. The switchboard is often located in the sub-floor area beneath the house, while cars park in a carport to the side or rear. This can make for a straightforward cable run in some layouts (straight through the sub-floor to the carport) or a more complex one if the carport is detached.
Brisbane's subtropical climate means outdoor charger placement needs more thought than in cooler cities. Direct afternoon sun on a west-facing wall can push a charger's operating temperature past its optimal range, reducing charging speed and shortening the unit's lifespan. A shaded wall or covered carport location is preferable.
Queensland has the highest rooftop solar penetration of any state, and this is where Brisbane EV charging gets genuinely compelling. If you are already generating solar power, a smart charger that coordinates with your inverter is one of the most effective ways to use excess generation. Many Brisbane homeowners charge their EV almost entirely from solar during the day — a full 60kWh charge from solar costs $0, compared to $4–8 from the grid depending on your tariff. That is effectively driving on free electricity.
For homes without solar, or for overnight charging, EV-specific tariffs help. Origin's EV Power Up plan offers a flat 8c/kWh rate. Queensland already has lower electricity costs than NSW or Victoria, so even standard rates are more favourable for EV charging.
Energex manages the distribution network across the Brisbane metro area and may require notification for high-draw charger installations (typically 22kW three-phase). Check their connection requirements before your electrician starts work.
Hiring a Licensed Electrician in QLD
Queensland electricians must hold a licence issued by the Electrical Safety Office (WorkSafe Queensland). EV charger installations require an Electrical Safety Certificate lodged after completion.
Ask your electrician about their experience with EV-specific installs. The continuous load requirements for charging circuits differ from standard power circuits, and proper cable sizing under AS/NZS 3008 for a 7kW or 22kW continuous draw is where mistakes happen most often.
