Installing an EV charger at home in Sydney isn’t just bolting a unit to the wall — the cost and the approach depend on your switchboard, your supply, and where the car parks. This guide breaks down what actually drives the price, the difference between 7kW and 22kW charging, single- vs three-phase, and when your installation needs a Level 2 electrician. Sydney Electrical Service installs home and business EV chargers across Sydney.

What’s involved in an EV charger installation?

A compliant home EV charger installation typically means a dedicated circuit run from your switchboard to the charger, its own protective device (an RCBO or equivalent), and a charger mounted where you park. The variables that change the job — and the price — are the distance from the switchboard to the parking spot, whether your switchboard has spare capacity, and whether your supply can handle the extra load.

7kW vs 22kW: which charger do you need?

Most Sydney homes install a 7kW single-phase charger. On a typical car that’s roughly a full overnight charge — more than enough for daily driving. A 22kW charger charges faster but requires three-phase power, which many older homes don’t have. Going to 22kW often isn’t about the charger at all; it’s about whether your property has (or can get) three-phase supply. For most households, 7kW is the practical, cost-effective choice.

Single-phase vs three-phase — and why it matters for cost

If your home is single-phase (most are), a 7kW charger usually fits within your existing supply, provided the switchboard has room and capacity. If you want faster charging or you’re adding other high-draw loads (a battery, ducted air conditioning), you may need to upgrade to three-phase — which is network-side work. That’s where a consumer mains upgrade and a switchboard upgrade can come into the picture, and where the job becomes Level 2 work.

What affects the cost of an EV charger installation in Sydney?

Rather than a single sticker price, the cost is driven by a handful of factors:

Cable run distance — a charger next to the switchboard is cheaper than one at the far end of the property or in a detached garage
Switchboard capacity — if your board is full or lacks an RCD, it may need work before the charger goes in
Supply capacity — whether your consumer mains can take the extra load, or need upgrading
Single vs three-phase — three-phase chargers and supply cost more
Charger model — tethered vs untethered, smart/load-managed features, and brand
Mounting — surface, pedestal, or weatherproof outdoor mounting

The honest answer is that a proper quote needs a quick look at your switchboard and parking setup. We provide a fixed-price quote before any work starts.

Smart charging and load management

Many modern chargers offer load management — the charger automatically limits its draw so it doesn’t overload your supply, and some can prioritise charging from rooftop solar or during off-peak periods. If you have solar or you’re worried about supply capacity, a load-managed charger is often what lets you install without a full supply upgrade.

Frequently asked questions

Can I install an EV charger on a single-phase home?

Yes — a 7kW single-phase charger suits most Sydney homes, as long as your switchboard has capacity and an RCD. It delivers a full overnight charge for typical daily driving.

Do I need a Level 2 electrician for an EV charger?

Not always. A straightforward 7kW install on an adequate single-phase supply is standard electrical work. You need a Level 2 ASP if the job requires upgrading your consumer mains or moving to three-phase — that’s network-side work.

Should I get a tethered or untethered charger?

A tethered charger has the cable permanently attached (convenient, no cable to carry); an untethered unit is tidier and lets you use your own cable. It comes down to preference — both are fine when installed correctly.
