How Much Does EV Charger Installation Cost in Perth?
Thinking about charging your EV at home in Perth? One of the first questions is cost. The honest answer is: it depends - but this guide from Volt Hub Electrical explains exactly what affects the price so you know what to expect, and how the Charge Up WA grants can help.
What affects the cost of EV charger installation
- The charger itself - 7kW single-phase units are the most common for homes; 22kW three-phase units cost more
- Cable run distance - how far the charger is from your switchboard
- Switchboard work - older boards may need an upgrade or a dedicated circuit
- Mounting and trenching - wall-mounted is simplest; longer or underground runs add labour
- Load management - sometimes needed so the charger doesn’t overload your supply
7kW vs 22kW chargers
Most Perth homes have single-phase power and use a 7kW charger, which fully charges a typical EV overnight. Homes with three-phase power can use a faster 22kW unit. We’ll recommend the right option for your car and your home’s supply.
Don’t forget the rebate
Eligible WA organisations may be able to reduce costs through the State Government’s Charge Up program. Read our Charge Up WA guide for details.

Frequently asked questions
- How much does it cost to install an EV charger in Perth?
- Most home EV charger installations in Perth vary with the charger chosen, the cable-run distance from your switchboard to the parking spot, and whether the switchboard needs an upgrade to handle the extra load. A licensed electrician assesses these on site before providing a written quote, so there are no surprises on the day.
- What affects the price of an EV charger installation?
- The main cost drivers are the charger unit itself (a 7kW single-phase unit versus a 22kW three-phase unit), the distance and mounting between the switchboard and the car space, any switchboard or RCD upgrade needed to meet AS/NZS 3000, and whether cabling has to run through walls, a roof space, or a trench.
- Do I need three-phase power for a home EV charger?
- No. A 7kW single-phase charger suits most Perth homes and adds roughly 40km of range per hour of charging. A three-phase charger (up to 22kW) charges faster but needs a three-phase supply and a compatible vehicle. A licensed electrician can confirm what your home's supply already supports.
- Does EV charger installation in WA need a licensed electrician?
- Yes. EV charger wiring must be installed by a licensed electrician and comply with AS/NZS 3000, and the electrician lodges the required electrical notification. Volt Hub is a licensed electrical contractor (EC16248) and handles the compliance and safety testing as part of the installation.
