What Affects the Cost
Detached garage cable runs. Melbourne's Victorian and Edwardian homes often have garages at the rear of the property, connected by a laneway. Cable runs of 20 to 30 metres are common and significantly increase cost.
Switchboard capacity. Older homes may need a
board upgrade before the charger circuit can be added, particularly if the board is already running solar and ducted heating.
Underground vs overhead cable routing. Getting cable to a detached structure means either trenching across the yard or running along fences and overhead. Trenching through an established garden or paved courtyard is the more expensive option.
Three-phase availability. Some newer Melbourne homes have three-phase supply, enabling faster 22kW chargers without additional supply work.
Dynamic load balancing (DLB). If your home already runs ducted heating,
split system air conditioning, or
ducted air conditioning, DLB lets the charger auto-reduce its draw when other loads kick in. CT clamps at the switchboard monitor total consumption and the charger adjusts in real time. This can avoid a switchboard upgrade entirely — a significant saving.
Smart charger features. Load management, solar integration, and app control add to the unit cost but reduce running costs.
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. Higher-end models include DLB and solar integration out of the box.
IP rating for outdoor installs. If your charger is going on a detached garage facing a rear laneway, exposed to Melbourne weather, look for IP65 minimum. This ensures protection against rain, dust, and hose splash.
Heritage overlays. Inner-suburb homes under heritage overlay may have restrictions on visible conduit runs. Surface-mounted conduit can be colour-matched to the facade and routed discreetly along cornices or down edges to minimise visual impact. Check with your local council before finalising the install plan.
A straightforward install with the charger on an attached garage wall within 10 metres of the switchboard and no board upgrade needed sits toward $1,500. A Victorian terrace in Carlton or Richmond with a detached rear garage, a 25m cable run requiring trenching, and a switchboard upgrade pushes toward $3,600.
Melbourne-Specific Considerations
Melbourne's housing layout creates a distinctive challenge for EV charger installation. Victorian and Edwardian terraces in suburbs like Fitzroy, Carlton, and Richmond typically park in rear laneways, with the garage (or car space) separated from the house by a courtyard or garden. The cable run from the switchboard, usually inside the house near the front, to the charger at the back can be 20 metres or more.
The routing options matter. Running conduit along fence lines or external walls is cheaper but needs to be weatherproof and UV-rated. In heritage overlay zones, visible conduit on the front of a building may not be permitted. Discuss this with your electrician and check with your local council before booking.
Melbourne's EV adoption is growing fast, and some inner-city apartment buildings are now installing shared charging infrastructure. If you are in a building with existing EV charging provisions, connecting to the shared system may be cheaper than a standalone install. CitiPower and Powercor cover most of metropolitan Melbourne's distribution network — and may require notification for high-draw charger installations (typically 22kW three-phase), so check their connection requirements early.
EV-specific electricity tariffs can dramatically reduce charging costs. Origin's EV Power Up plan offers a flat 8c/kWh rate, and AGL's Night Saver EV plan drops to around 8c/kWh for overnight charging (midnight–6am). If you are charging at home most nights, the tariff you are on matters as much as the install cost. A 60kWh charge at 8c/kWh costs about $4.80 — a fraction of petrol.
Hiring a Licensed Electrician in VIC
Victorian electricians must hold a licence registered with Energy Safe Victoria (ESV). EV charger installations require a Certificate of Electrical Safety (CES) lodged with ESV after completion.
Look for an electrician who has done multiple EV installations. The continuous load rating requirements for EV circuits are stricter than standard power circuits, and incorrect cable sizing under AS/NZS 3008 is one of the most common mistakes in charger installs.
