Rowville sits on the boundary between two electricity networks, and both of them supply homes in the 3178 postcode. That is the first thing we pin down for any EV charger installation Rowville homeowners ask us to quote, because it decides whose portal the paperwork goes through and who carries out any supply upgrade. We cover Rowville from our Beaumaris premises at 125 Charman Rd, about 18 km away as the crow flies, and our A-grade electricians do the work under REC 35838.
EV charger installation Rowville starts with your network
The postcode network locator published by CitiPower and Powercor lists both United Energy and AusNet against Rowville 3178. Its data stops at the suburb level, so we never guess from a street name. We confirm the network for your address at the site check, from the meter and supply details.
The electrical work itself is the same on either side of the line. What changes is the administration around it:
| Step | Home on the United Energy network | Home on the AusNet network |
|---|---|---|
| Registering the wall charger | Wall and fast chargers must be registered through United Energy’s myEnergy service | We confirm AusNet’s current connection requirements before the job |
| Supply upgrade, such as single-phase to three-phase | Lodged through myEnergy, United Energy’s online connection service | Lodged through EnergyConnect, AusNet’s portal for electricity service applications |
| Wiring, testing and certificate | AS/NZS 3000 Wiring Rules, six mandatory tests, Certificate of Electrical Safety | Identical |
United Energy sets out its charger rules in its home EV charging guidance, and AusNet explains its upgrade route on its page for managing an existing electricity supply. We handle the applications either way, so you do not need to learn two systems.
The network matters most when a job involves the supply itself. Under the Victorian Service and Installation Rules, the distributor needs advance notice of that work, and it reconnects or alters the supply only once it receives the Certificate of Electrical Safety. Where a network crew has to attend, the appointment is booked with whichever network owns your street’s supply, so knowing it early saves time.
Big households, no railway station
Rowville is built around the car. At the 2021 Census, 91.8% of occupied dwellings were separate houses and fewer than 1% were flats or apartments. Some 44.8% of households had two vehicles and 28.3% had three or more, an average of 2.2 per home, while just 2.2% had none.
Geography explains a lot of that. There is no railway station in Rowville. Knox’s public transport network includes the Belgrave line, SmartBus and local bus routes, and Knox’s planning policy for the Rowville activity centre supports a new and expanded bus interchange at Stud Park. EastLink runs along the suburb’s western edge in the Dandenong Creek flood plain, and part of Churchill National Park lies in its south. For an EV household here, the driveway is the main refuelling stop.
The good news is that an ordinary home charger keeps up. CitiPower’s published figure for a 7 kW single-phase wall charger is 30 to 40 km of range for every hour of charging, so an eight-hour overnight session adds roughly 240 to 320 km.
That shifts how we plan. In our view, a Rowville house with three cars should be wired for two chargers from the start, even if only one goes on the wall this year. A second cable or empty conduit to the other side of the garage, and a charger that supports load sharing, cost far less effort now than a second visit later. Our home EV charger installation process includes that planning conversation.
Houses from the 1970s onward and their switchboards
Rowville’s undulating grazing land attracted housing from about 1970, and the Stud Park shopping area followed in 1989. A house from the 1980s or 1990s may have picked up air conditioning, a pool pump or a home office since it was built, each drawing on the same switchboard. If the roof already carries solar panels, a charger that can follow solar output lets a car parked at home soak up daytime generation.
Say your switchboard is in the garage, a few metres from where the car parks. The run is short, but the board may still need work. We give a new charger circuit its own Type A or Type B safety switch, because Type AC devices were ruled out for new installation work from 1 May 2023. If there is no room, or the board is old enough that adding to it would be poor practice, our switchboard upgrade for EV charging work brings it up to date. A main switchboard replacement is prescribed work, inspected by a Licensed Electrical Inspector before it is switched on.
If you are adding a carport for an extra car, Knox’s neighbourhood character policy asks for single crossovers and for car storage that does not dominate the street, so check the design before you commit to a location for the charger.
A terminal station nearby is not spare capacity at your meter
Rowville is centred roughly on the corner of Wellington and Stud Roads, where an electricity terminal station and the Stamford Hotel were built in the 1950s and 1960s, and state mapping still shows Rowville and East Rowville terminal stations today. It is tempting to assume all that infrastructure means a house nearby can take any charger. It does not work like that.
Terminal stations feed the high-voltage network. What your home can draw is set much closer to home: the service cable, the main switch, the switchboard and the local distribution network in your street. We calculate the home’s maximum demand before choosing a charger, because a figure above 100 amps per phase triggers the limiting-device requirement in the Victorian Service and Installation Rules. If you need more than a single-phase supply can give, the three-phase power upgrade goes through whichever network supplies your address.
United Energy says plainly that some homes may need upgrades to their power supply to manage the load of EV charging, and the same physics applies on AusNet’s side. An upgrade usually means new consumer mains from the point of supply to your switchboard, which is prescribed work, then the network connecting the new supply once it has the certificate.
Knox Council, public chargers and Stud Park
Knox City Council adopted an Electric Vehicle Charging Infrastructure Policy at its 10 June 2025 meeting. The Knox EV charging infrastructure policy guides public chargers on council land, names shopping centres and community hubs as examples of preferred locations, and requires council chargers to run on 100% renewable energy. Charging fees started on 1 July 2025 through the Exploren app.
When the policy was adopted, the council’s five public chargers were at the Knox Civic Centre in Wantirna South and at Fairpark Reserve and the Knox Regional Netball Centre in Ferntree Gully, so none was in Rowville. By 2028 the policy aims to help expand public charging across Knox’s priority sites, in line with a Climate Response Plan that targets net zero community emissions by 2040. Until that happens, a home charger is the practical everyday option.
The centre of the suburb is changing too. Knox’s activity centre policy supports expanding Stud Park Shopping Centre, turning Fulham Road into a main street, and adding apartments in the commercial core. In the surrounding Local Living area the policy supports two and three dwellings on a lot, so a knock-down and rebuild is the right moment to run a charger circuit to every garage. Residents of future apartment buildings will need shared charging, which our strata and apartment charging service is set up for. Off Stud Road, the Stamford Park Homestead, built in 1882 and restored by Knox Council, is a reminder of how recently this was grazing country.
Frequently asked questions about EV charging in Rowville
How do I find out whether my Rowville home is on United Energy or AusNet?
The postcode locator lists both networks for Rowville 3178, so it cannot settle the question for a single address. We confirm it from your meter and supply details during the site check, before any application is lodged.
Does the network change which charger I can install?
The wiring standard, testing and certificate are the same on both networks. Network requirements and the application route differ, so before a 32 amp single-phase charger goes on the wall, or a supply upgrade is lodged, we confirm what your network expects at that address.
Are there council-run public chargers in Rowville?
None were on the list Knox published when it adopted its EV charging policy in June 2025: its five public chargers were in Wantirna South and Ferntree Gully. The policy now guides where future public chargers on council land should go.
We have three cars. Can the house charge two EVs at once?
Usually, with planning. With 28.3% of Rowville households running three or more vehicles in 2021, we can fit the first charger with a spare conduit for the second, then set the pair to divide the current the supply has available. If the house is already close to its maximum demand, we discuss a supply upgrade through your network.
Is a 22 kW charger worth it on a three-phase Rowville home?
Only if your car can use it. A 22 kW wall unit needs three-phase power, as United Energy’s guidance points out, but the car’s onboard charger sets the real limit on AC charging. If your car’s onboard charger accepts less than 22 kW, a wall unit matched to that limit charges it just as fast.
Is Rowville too far from your Beaumaris premises?
No. Our premises at 125 Charman Rd, Beaumaris, is about 18 km from the middle of Rowville in a straight line, and our phone line takes bookings for site checks Monday to Saturday, 7am to 7pm.
When you are ready, ask for a Rowville charger quote on our contact page, or speak to us on 1300 003 853. Our EV charger installation Beaumaris page describes the premises we work from, and for Wheelers Hill, which meets Rowville across the Dandenong Creek, see EV charger installation Wheelers Hill.
