EV charger installation is the process of hardwiring an electric vehicle charging station to a property's electrical supply, sizing the consumer mains and switchboard to handle the load, and commissioning the unit to charge safely overnight. DM Electrical installs all major EV charger brands, including Tesla Wall Connector, Ocular, Fronius Wattpilot, Wallbox, EVSE, ZJ Beny, and other AC chargers, across Sydney's Northern Beaches, North Shore, Inner West, Eastern Suburbs, and CBD, for single-vehicle homes, multi-car households, and workplace destinations.
The Supply Check Comes First
Most EV charger jobs are not actually about the charger. They are about whether the existing switchboard, consumer mains, and service line can support a 7 kW single-phase or 22 kW three-phase load without tripping the main switch every time the dryer runs at the same time. DM Electrical assesses the supply first, recommends whether to upgrade the switchboard or add load management, and installs the unit on a dedicated circuit with the correct RCD type for EV charging (Type B or Type A with DC fault detection, depending on the charger). The work is signed off with a Certificate of Compliance and the install is documented so the charger qualifies for any applicable NSW or vehicle-manufacturer rebate.
EV Charger Installation Services
- Single-phase 7 kW installs. The standard residential install, adds about 40 km of range per hour, suits most single-vehicle households.
- Three-phase 11 kW or 22 kW installs. For multi-EV households or high-utilisation users; requires 3-phase supply, often paired with a consumer mains upgrade. Not sure if you need it? See whether your home needs three-phase power.
- All major charger brands installed. Hardwired installs of Tesla Wall Connector, Ocular, Fronius Wattpilot, Wallbox, EVSE, ZJ Beny, and other AC chargers, including Wi-Fi commissioning and load sharing across multiple units where supported.
- OCPP and app-controlled chargers. OCPP-compatible chargers like Ocular and Fronius Wattpilot configured for app control, time-of-use scheduling, or solar-export-aware charging.
- Load management and dynamic balancing. Smart chargers configured to throttle automatically when the rest of the house pulls high load, avoiding any need for a service upgrade.
- Workplace and strata installs. Multi-bay commercial installs with backend billing, access control, and OCPP integration for property managers and employers.
EV Charger Installation Cost in Sydney
The install price is set by the distance from your switchboard to where you park, whether the board has a spare way and enough capacity, and whether the job stays single phase or moves to three phase. The charger unit itself is usually the predictable part. Every job below is quoted fixed-price after a site visit, with the compliance certificate included rather than added afterwards.
| Install type | Typical cost | What moves the price |
|---|---|---|
| Single phase 7 kW, charger supplied separately | $1,200 to $2,400 | Cable run length from the board to the parking space, and any switchboard work needed |
| Three phase 11 kW or 22 kW | $2,400 to $5,500 | Whether three phase already exists at the property, and consumer mains capacity |
| Install requiring a consumer mains upgrade | $2,400 to $5,500 | Overhead or underground mains, run length, and trenching where underground |
| Workplace, strata, or multi-bay | Quoted on site | Bay count, load management, billing backend, and civil works |
| Charger unit supplied by us | Quoted with the install | Brand, kW rating, tethered or socketed, OCPP capability |
7 kW, 11 kW or 22 kW: Which Charging Speed You Need
Charger speed is limited by two separate things: the supply at your property, and the onboard AC charger inside the car. Paying for a 22 kW charger does nothing if the vehicle caps its onboard charging at 11 kW, which most current EVs do. The practical answer for the large majority of Sydney households is a single phase 7 kW unit, because a car that is parked overnight has twelve hours to recover a commute that took forty minutes.
| Charger | Supply needed | Range added per hour | Best for |
|---|---|---|---|
| 7 kW single phase | Standard single phase | About 40 km | Most households with one EV charging overnight |
| 11 kW three phase | Three phase supply | About 60 km | Two EVs sharing a charger, or high daily distances |
| 22 kW three phase | Three phase with capacity to spare | About 120 km | Workplaces, fleet depots, and vehicles that accept 22 kW AC |
Do You Need a Switchboard Upgrade for an EV Charger?
Not always, and this is where a site visit saves money. A charger needs a dedicated circuit, a spare way on the board, and the correct RCD protection for DC fault current. If the existing board is a modern one with room to spare, the charger goes in beside it and nothing else changes. If the board still runs ceramic fuses, has no RCD protection, or has no spare ways, it has to be brought up to standard first, because adding a continuous 32 A load to a board already at its limit is how you end up tripping the main switch every evening.
The other path is load management, and it is often the cheaper answer. A smart charger can be configured to monitor total household draw and throttle itself when the oven, dryer, and air conditioning are all running, then return to full speed once the house quietens down. That keeps the peak demand inside what the existing mains can carry and avoids a supply upgrade entirely. We assess both options and quote whichever genuinely fits, rather than defaulting to the larger job. Where an upgrade is the right call, we do it in house under our Level 2 accreditation as part of the same visit. See switchboard upgrades for what that involves.
Our Process
- 1Site visit and supply check. We inspect the switchboard, measure the existing consumer mains, confirm single-phase or 3-phase, and recommend whether load management or a supply upgrade is needed.
- 2Fixed-price quote. Quote covers the charger (supplied or BYO), cable run, RCD or Type B protection, switchboard work, and the compliance certificate.
- 3Install and commissioning. Most residential installs complete in a single day, including the Wi-Fi setup, vehicle pairing, and a charge cycle to confirm operation.
- 4Compliance and rebate paperwork. Certificate of Compliance issued and lodged, plus install documentation packaged for any NSW or vehicle-OEM rebate claim.
Why DM Electrical
- Charger-agnostic recommendation. We sell and install the right charger for your car and supply, not the one with the best margin. Tesla, Ocular, Fronius, Wallbox, EVSE, ZJ Beny, and other major brands all installed regularly.
- Level 2 in-house for supply upgrades. If your switchboard or consumer mains need uprating, we do that under the same job rather than handing you to a second contractor.
- Future-proofed installs. Cable runs and switchboard layouts are sized so a second charger or upgrade later is a half-day job, not a full rewire.
Installing an EV Charger at Home
To install an EV charger at home, an electrician runs a dedicated circuit from your switchboard to where you park, fits the correct RCD protection, mounts the unit, and commissions it to charge safely overnight. For most Sydney homes a single-phase 7 kW home charger is the right call. As a Level 2 ASP, DM Electrical handles any switchboard or consumer mains upgrade the load needs in-house, so the whole job is done by one team in a single visit. If you are searching for an EV charger installer near you on the Northern Beaches or across Sydney, home EV charger installation is core work for us. For a full walk-through of charger types, costs, brands, and what to plan for, read our home EV charger installation guide. Running chargers for a workplace, strata car park or depot is a different job, driven by the site's supply capacity: see our guide to commercial EV charger installation.
Frequently Asked Questions
How long does it take to install an EV charger?
Most residential installs are completed in a single day, including pulling cable from the switchboard to the charger location, installing the RCD or Type B protection, mounting and commissioning the charger, and issuing the Certificate of Compliance. Switchboard upgrades or consumer mains work, where required, add half a day to a day.
How much does an EV charger install cost in Sydney?
A straightforward single-phase 7 kW install on a Northern Beaches home with the charger supplied separately typically ranges from $1,200 to $2,400 depending on cable run length and switchboard work. Three-phase installs and jobs requiring consumer mains upgrades typically sit between $2,400 and $5,500. We provide a fixed-price quote after the site visit.
Do I need a 3-phase supply for an EV charger?
No, single-phase 7 kW is enough for most households, it adds about 40 km of range per hour and fully recharges most EVs overnight. Three-phase 11 kW or 22 kW is worth considering for multi-EV households, very high daily km, or workplace installs.
Will an EV charger trip my main switch?
Not if it is installed and configured correctly. Smart chargers can be set to throttle when the rest of the house pulls high load, which avoids tripping the main switch and removes the need to upgrade the service in most cases. We configure load management as part of the install.
Which charger brand should I buy?
It depends on your vehicle, supply, and how you plan to use the charger. Tesla Wall Connector is clean if you own only Tesla vehicles. Ocular, Fronius Wattpilot, Wallbox, and other OCPP units suit households with a mix of EV brands, solar systems, or a desire for app-level control over scheduling. EVSE and ZJ Beny are popular value options. We install all major brands and discuss the trade-offs before recommending.
Can I claim a rebate on my EV charger install?
Eligibility depends on the program and changes regularly. Some vehicle manufacturers offer installer credits, and various NSW and federal programs cycle in and out. We document the install (compliance certificate, photos, serial numbers) so any rebate claim can be lodged without missing paperwork.
