Ready Support
How long does EV charger installation take?
Most standard installations take around 2–4 hours. Jobs involving extended cable runs, switchboard upgrades or more complex electrical work may take longer. We’ll assess the job beforehand and give you an estimated timeframe so you know what to expect.
Are your technicians licensed and insured?
Yes. Our electricians are fully licensed and insured, and all work is carried out in accordance with applicable Victorian electrical safety requirements and standards.
Do you provide free quotes?
Whether a quote is free depends on the scope of the job. Get in touch with our team to discuss your installation and find out more about the quoting process.
What areas of Victoria do you service?
We cover Melbourne and surrounding suburbs across the greater Victoria region. Get in touch if you’re unsure whether we service your area.
Do you offer warranties on your work?
Yes, we offer warranties on our installation and repair work and stand behind the quality of our services.
Do I need a switchboard upgrade for an EV charger?
Not always. Many properties can accommodate an EV charger using their existing switchboard. However, older switchboards or systems with limited electrical capacity may require an upgrade. We’ll assess your existing setup and explain any recommended changes before proceeding with the installation.
How much does an EV charger installation cost?
The cost depends on the charger you choose, its distance from the switchboard and whether any electrical upgrades are needed. Most standard home installations are relatively straightforward. Let us know about your setup and we’ll provide a price before getting started.
Can I install an EV charger on single phase power?
Yes. Most Melbourne homes have single-phase power, which can generally support a 7kW charger, providing around 40km of range per hour. Properties with three-phase power can support chargers up to 22kW, provided the vehicle is compatible.
Do you supply the charger or do I buy it myself?
You can choose either option. We can supply and install a charger that suits your vehicle and budget, or install one you’ve already purchased. If you’re unsure which model to choose, we can help you compare your options.
Which EV chargers do you install?
We install a range of leading EV charger brands available in Australia, including Tesla, Zappi, Fronius, Wallbox and Ocular. If you have a particular model in mind, let us know and we’ll check whether it’s suitable for your property.
How far can the charger be from my switchboard?
We can accommodate most locations, including garages, carports and driveways. Longer cable runs may increase the cost and require thicker cabling to manage voltage drop. We’ll assess the distance and recommend a suitable setup before installation.
Can I get a charger installed in an apartment or townhouse?
Yes. Although strata installations may require additional planning and approval from your owners’ corporation. We’ll also need to assess the power supply and how electricity usage will be measured and billed. Our team can help you understand what’s involved.
Do I need council approval to install an EV charger?
A standard home EV charger installation in Victoria generally doesn’t require council approval. However, the work must be completed by a licensed electrician and comply with applicable electrical safety requirements, including AS/NZS 3000. We’ll take care of the electrical work and compliance requirements.
Can my EV charger run off solar?
Yes. A compatible smart charger can use electricity generated by your solar panels to charge your vehicle during the day. If you already have a solar system, let us know your inverter model so we can recommend a charger that works with your setup.
Why not just use the cable that came with my car?
The portable charging cable supplied with most EVs plugs into a standard power point and charges much more slowly, often taking 15–20 hours to fully charge a battery. It’s useful for occasional charging, but a dedicated wall charger offers faster charging and is designed for regular use.
How long does it take to charge an EV at home?
A 7kW wall charger can charge most EVs from nearly empty to full overnight. The actual charging time depends on the battery capacity and its current charge level. Most drivers simply top up their vehicles as needed rather than waiting for the battery to run flat.
Can the charger be installed outside?
Yes. Many EV chargers are designed for outdoor installation and have weather-resistant enclosures suited to Melbourne’s conditions. We’ll choose a practical mounting location near your parking space and make sure the charging cable can comfortably reach your vehicle.
Do you install chargers for businesses?
Yes. We install EV chargers for workplaces, fleet depots, apartment buildings and retail premises. Larger installations may require load management to distribute available power across multiple chargers, which we’ll factor into the installation plan.
Can you fix or replace an existing EV charger?
Yes. We can diagnose faults, repair chargers, replace faulty units and assess existing installations that may not have been completed correctly. If your charger keeps disconnecting or tripping the circuit, get in touch and we’ll investigate the issue.
Do I need to be home during the installation?
Someone aged 18 or over needs to be present to provide access and confirm the charger’s preferred location. You don’t need to stay with our electricians throughout the job. Before leaving, we’ll explain how the charger works and provide the relevant paperwork.
Will I get a Certificate of Electrical Safety?
Yes. We provide a Certificate of Electrical Safety for every installation where required under Victorian regulations. It confirms that the electrical work has been completed in accordance with the applicable requirements. Keep a copy for your records, as your insurer may request it.
