What does an EV charger cost to install? About $2,000 — but the charger isn't the variable.

For a standard 7 kW single-phase home charger professionally installed, most households pay roughly $1,200 to $2,300 all-in, with industry data putting the median complete installation around $2,150 and the full range running from about $800 to over $5,000. City figures reported in 2026 sit inside that band — Sydney roughly $1,100–$2,200, Melbourne $1,200–$2,200, Brisbane $1,400–$2,200 — with the Solar Choice EV Charger Price Index putting the NSW average near $2,309 including GST. The charger hardware is $600–$3,000 (a good 7 kW smart unit is roughly $700–$1,300), cable runs cost about $30–$50 per metre, and a switchboard upgrade adds $1,200–$2,500. Around 30–45% of homes need some electrical upgrade work, and that is what turns a typical job into an expensive one. Always get a site inspection before accepting a fixed price.

Because the charger is the predictable part of the bill and the house is not. The two variables that dominate are the distance from your switchboard to where the car parks, charged at roughly $30 to $50 per metre and much more if the cable has to cross a driveway, penetrate a slab or reach a detached garage, and whether your switchboard can take the load. Roughly 30 to 45% of homes need electrical upgrade work, and a switchboard upgrade adds $1,200 to $2,500 on its own. A quote that looks unusually cheap frequently has no switchboard allowance in it at all, which is not a saving, just a variation you have not been shown yet. This is why quotes given over the phone from a photo of the meter box are unreliable. Insist on a site inspection, or at minimum a quote that states its allowance and spells out exactly what triggers a variation.

For almost every Australian household, yes. A 7 kW single-phase charger adds very roughly 40 km of range per hour, so a ten-hour overnight charge delivers around 400 km — far more than typical daily driving. The upsell to 11 kW or 22 kW three-phase usually fails on two counts. Most homes do not have three-phase power and adding it often costs more than the charger itself. More importantly, the limit is usually the car rather than the wallbox: many popular EVs cap their onboard AC charging at 7 to 11 kW, so a 22 kW unit would deliver an identical overnight result at a higher price. The right question is not how fast the charger can go but whether it finishes by morning. If 7 kW does, faster hardware buys you nothing you will notice. Spend the difference on solar-surplus matching and proper scheduling instead.

Yes. Home EV chargers are designed for outdoor installation and carry an ingress protection rating for exposure to rain and dust — look for an IP rating appropriate to the position, and check the manufacturer's stated operating temperature range if the wall gets full afternoon sun. Practical considerations matter more than whether it is technically permitted. Mount it where the cable reaches the car's charge port comfortably without stretching across a walkway, at a height that is convenient to plug in, and ideally where it is not baking in direct western sun all summer, since heat shortens the life of any power electronics. If the location is exposed or public-facing, consider a unit with a lockable holster or app-based access control. Your electrician will also factor the outdoor run into the cable cost, which is charged roughly by the metre, so a charger on an external wall far from the switchboard costs more than one directly behind it.

Five things. A licensed electrician and a certificate of electrical safety issued on completion, because EV charger installation is licensed electrical work under AS/NZS 3000. A dedicated circuit with its own correctly rated breaker and RCD protection, rather than a spur off an existing circuit. A load assessment confirming your supply can carry the charger alongside other major loads such as ducted air conditioning, an induction cooktop or heat pump hot water. Network notification or approval where your distributor requires it for a charger above a given rating, which your installer should handle and confirm. And commissioning — the app set up, scheduling configured, and someone showing you how to charge off-peak or from your solar surplus. That last item is worth more than it sounds, because a charger that is never scheduled properly will quietly charge at peak rates for years.

Most EVs come with a portable emergency cable that plugs into an ordinary 10 amp power point. It works, and for a plug-in hybrid or a very low-kilometre household it can genuinely be enough. But it is slow — typically around 2 to 2.4 kW, so roughly 10 to 15 km of range per hour, meaning an overnight charge might add only 100 to 150 km. It also draws near the continuous limit of a standard power point for many hours at a time, so it should never be run through a domestic extension lead or a piggyback adaptor, and an old or shared circuit is worth having an electrician check. A dedicated 7 kW wallbox is roughly three times faster, safer for daily use because it is on its own protected circuit, and is the only option that supports solar-surplus matching and proper scheduling — which is where the actual running-cost saving comes from.
