Most EV owners do not think about their home charger until the car arrives in the driveway. By that point, the install is a rush, and rushed installs go wrong.

Home charging is the cheapest, easiest, most reliable way to keep an electric vehicle on the road. Plug in at night, wake up to a full battery, pay residential power rates instead of public-charging prices. Once the install is done well, you never think about it again.
The catch is that a typical 7kW wall charger draws around 32 amps continuously for several hours at a time. That is far more sustained load than most Sydney homes were originally wired to handle on a single circuit. Older switchboards, undersized service mains, and shared driveways all add complications that only show up once an electrician is on site.
Before we put a charger on a wall, we walk through three questions with the homeowner. The answers tell us whether this is a half-day job or a full Level 2 service upgrade.
Cable runs cost money. A charger that sits four metres from the switchboard is a clean, quick install. A charger that needs to run twenty metres around the side of the house, through a brick wall, and into a garage on the other side of the property is a different job entirely. We look at the parking spot, the switchboard location, and what walls or paths the cable can follow before we quote.
Single-phase supply is what most Sydney homes have. It supports up to 7kW chargers comfortably, which adds around 40km of range per hour. Three-phase supply, more common in newer or commercial premises, supports 11kW and 22kW chargers, doubling or tripling that charging speed. If you have a high-mileage EV or two cars to charge, three-phase is worth the conversation.
Ducted air-con, an induction cooktop, a heat pump, a pool pump, and an EV charger all running at once may exceed what your mains can deliver. We calculate the load and either find capacity in the existing supply, recommend a smart charger that throttles based on house demand, or quote a service upgrade. We will tell you upfront which one applies.
If your main service cable, meter, or switchboard cannot handle the additional load of an EV charger, you need a Level 2 ASP. We are accredited, which means we handle the service upgrade in-house instead of subcontracting it out. That keeps the timing tight and the responsibility clear.
A typical Level 2 upgrade for an EV install involves coordinating with Ausgrid, replacing or rerating the service cable, updating the meter, and connecting the new circuit to a modern switchboard. It usually adds a day to the install, sometimes less.
Most residential installs land between two and four hours on site. We arrive, isolate the existing supply, run the new dedicated circuit from the switchboard to the charger location, mount and wire the charger, commission the unit, walk you through the app, and certify the work for NSW Fair Trading. You drive in, plug in, and you are charging.
If we need to upgrade your switchboard or service, we quote that work separately and upfront. It is not a hidden extra. Some homeowners do the upgrade at the same time as the charger; others spread it over two visits. Either way, you know the full picture before we start.
We hand over the Certificate of Compliance for Electrical Work, the manufacturer warranty paperwork, and a quick rundown of the app. We register the install with the manufacturer where possible. If anything plays up in the first twelve months, you call us and we come back at no charge.
Booked the right way, your home charger should be invisible. You plug in at night, you drive in the morning, and you forget the install ever happened. That is the goal, and that is what a properly scoped Sydney install delivers.
If your safety switch is more than ten years old, or it trips for no obvious reason, it is already telling you something.
Federation cottages, post-war fibros, 1970s brick veneers. They share one thing. Their switchboards were not built for 2026.
Sydney's southerly busters and east-coast lows do more damage to home electrical systems than most homeowners realise. Most of it is preventable.
