Berwick sits on a different electricity network from the bayside suburbs around our Beaumaris and Brighton premises, and we raise it early in every EV charger installation Berwick enquiry. Postcode 3806 is supplied by AusNet, not United Energy, so supply upgrades go through AusNet’s own portal and assessment. The suburb is in the City of Casey, one of the two municipalities in Melbourne’s south-east growth corridor, and its housing is overwhelmingly family homes: 89.0% separate houses at the 2021 Census, more than half with four or more bedrooms.
Our nearest base to Berwick is the Beaumaris premises at 125 Charman Rd, roughly 27 km away in a straight line. We are upfront about that distance, and we plan around it so your job is done in as few visits as possible. Our A-grade electricians supply and install chargers, fit units provided by your car dealer, and handle any switchboard or supply work the charger needs.
EV charger installation Berwick on the AusNet network
In CitiPower and Powercor’s postcode lookup, Berwick and neighbouring Harkaway both come up as AusNet. AusNet describes its distribution network as serving “the fringe of the northern and eastern Melbourne metropolitan area and the eastern half of rural Victoria”. For a charger on an existing supply, the work is ours to design, install and certify. When the supply itself has to change, the application goes through AusNet’s EnergyConnect portal, which AusNet calls its portal “for all electricity service applications, including supply, major connection, solar and metered connections”.
AusNet does not appear to publish a dedicated home EV charger page, so we work from the Victorian Service and Installation Rules that all Victorian networks use, plus AusNet’s connection requirements for each application. Where the rules give advisory limits for large single-phase loads, such as a 32 A charger, we check what applies before we fit it rather than assuming. AusNet’s page on how to manage the existing electricity supply for your home sets out the application side.
Growth corridor demand and what it means for upgrades
AusNet’s 2026 to 2030 distribution annual planning report describes the south-east growth corridor, covering Casey and Cardinia, as “a rapidly developing region”. It lists Berwick North among the seven zone substations on its Eastern Cranbourne 66 kV sub-transmission loop, and says AusNet has identified increasing energy at risk on that loop because of rapid demand growth in the corridor.
None of that stops a household fitting a charger. It does mean bigger requests, such as a three-phase upgrade for two fast chargers, are assessed by AusNet against local capacity rather than rubber-stamped. Our view is that most Berwick households are better served by a smart 7 kW charger scheduled overnight or to follow rooftop solar than by chasing the biggest possible supply. If your driving genuinely needs more, our three-phase upgrades page explains the process, and we lodge the AusNet application early so it does not hold up the install.
Four-bedroom homes and two-car garages
Berwick’s housing makes the charging itself fairly straightforward. Most homes are separate houses, 52.8% have four or more bedrooms, and the average household had 2.1 vehicles in 2021, with 23.4% running three or more. A double garage with an internal wall close to the switchboard is about the easiest site there is: a short run, a protected spot for the charger, and room for a second unit later.
The details still matter. A newer switchboard may have space for a dedicated circuit but not the right protection for it, because Type AC safety switches can’t be used in new work any more, and they may not pick up the DC leakage an EV charger can produce. Two EVs on one single-phase supply usually call for load sharing so both cars charge overnight without overloading the house. Our home EV charger installation page covers charger choices, and a switchboard upgrade for EV charging is quoted at the same time if the board needs it.
Bigger homes also carry bigger loads. Ducted heating and cooling, a pool pump and induction cooking can already use a large share of a supply before a car is plugged in. On a large all-electric home we therefore run the maximum demand calculation before recommending a charger size, because the Victorian Service and Installation Rules require demand-limiting devices once an installation’s calculated maximum demand exceeds 100 A per phase.
The old township: tall trees and the landscape overlay
Around the original village and High Street, trees define the streetscape. Schedule 4 to the Significant Landscape Overlay in the Casey Planning Scheme covers “Berwick Township and Environs” and describes its character as coming from “a predominance of tall, mature Australian and exotic trees on both private properties and the roadway”, with deep front setbacks, few front fences and wide verges.
Under the Berwick Township and Environs landscape schedule, removing, destroying or lopping a tree whose trunk circumference exceeds 0.5 metres (or whose diameter exceeds 16 centimetres) one metre above the ground needs a permit, apart from pruning and dead wood. Clause 62.02-2 generally takes the charger itself out of the buildings-and-works permit net. So on a treed township block, we design the cable route around the big trees and their drip lines, favour the house side of the driveway, and avoid any trench that would put a significant tree’s roots at risk.
Heritage on High Street and around Gloucester Avenue
Casey’s Heritage Overlay schedule includes dozens of Berwick places. Along High Street there are the Berwick Inn at 1 to 9 High Street, the Mechanics Institute and Free Library at 13 to 15, the former post office and courthouse at 102 to 104, and the High Street Avenue of Honour. Nearby are St Margaret’s School on Gloucester Avenue and several houses and gardens on Brisbane Street, while Wilson Botanic Park on the Princes Highway and the Old Cheese Factory on Homestead Road are also listed.
If your home is one of them, the Heritage Overlay’s test is simple: a charger visible from the street, or from a public park, needs a planning permit under clause 43.01-1, although a lane does not count as a street for this purpose. Such applications skip public notice and third-party review, yet the simplest path is still a position out of street view: inside the garage, on a rear wall, or behind the line of the house. We check the overlay before we quote so there are no surprises.
Planning a job about 27 km from our Beaumaris base
Distance is the reason we front-load the planning. Photos of the switchboard, meter box and parking spot let us arrive for the site visit already knowing most of the answers. At the visit we measure the cable route, check the planning overlays and confirm whether AusNet needs to be involved. The written quote spells out the charger, the circuit and any upgrades. On install day the circuit and charger go in and are put through Energy Safe Victoria’s six mandatory tests, after which we issue your Certificate of Electrical Safety (DUKE EV is REC 35838).
Our hours run Monday to Saturday, 7am to 7pm, so ask about a Saturday booking if you commute during the week. Building or renovating? Ask for a dedicated cable or an empty conduit from the switchboard to the garage while the walls are open; it is much simpler than retrofitting, and it leaves the choice of charger for later.
Solar, scheduling and the evening peak
Family homes with big roofs suit solar, and a smart charger can follow the panels’ output so the car soaks up daytime generation. As Solar Victoria points out, energy the car takes during the day is energy the house cannot use that evening, and a home battery is one way to hold midday solar for overnight charging. For households away during the day, scheduling the charger for off-peak hours under a time-of-use tariff is the practical alternative. Our solar-aware EV charging page covers both set-ups.
Bidirectional charging, where the car can power the house or export to the grid, is now provided for in the Australian inverter standard. It only works when the car and the charger are both bidirectional, though, and like any grid-connected inverter it needs the network’s approval. For most Berwick homes it is a future option, so we size the circuit and leave room at the switchboard rather than asking you to pay for bidirectional hardware today.
Frequently asked questions before a Berwick install
Is Berwick on the same network as the bayside suburbs?
No. Berwick is supplied by AusNet, while suburbs such as Beaumaris and Mentone are on United Energy. The charger installation is the same; supply upgrades follow AusNet’s process.
Do I need a permit for a charger under the Berwick landscape overlay?
Not for the charger itself, which is generally exempt under clause 62.02-2. A permit is needed if the work would remove, destroy or lop a tree above the overlay’s size threshold, so we route cables to avoid that.
Is a home charger in Berwick eligible for a state rebate?
Not that we could find: as at October 2026 we found no Victorian Government rebate for home EV chargers. If one appears before you book, we will point it out in the quote.
How can I check that an electrician is licensed?
Energy Safe Victoria keeps a public register of licences and registrations. DUKE EV is a registered electrical contractor, REC 35838.
Can you pre-wire a home that is still being built?
Yes, if the builder gives us access at the right stage. We can run the circuit, or an empty conduit, to the garage so the charger can be added later without opening walls.
Which DUKE premises looks after Berwick?
Our Beaumaris premises at 125 Charman Rd, roughly 27 km from the centre of Berwick in a straight line, so we collect photos first and make the site visit count.
Whether your home is a new build with a double garage or a weatherboard on a treed township block, the first step is the same: a few photos and a site visit. Send an enquiry through our contact page and reply to our email with the photos; if you would rather talk it through, phone 1300 003 853 on any day from Monday to Saturday, 7am to 7pm. Our Beaumaris premises page has more about the base our electricians travel from.
