The best time to plan an EV charger is before garage walls, driveway surfaces and electrical routes are finished. You do not need to choose the fastest charger available. You need an arrangement that suits the vehicle, daily driving, parking position and the home’s assessed electrical capacity.
A renovation can make installation easier because other electrical and building work is already being coordinated. It can also create competing demands from new cooking, heating and hot water appliances. Have a licensed electrician assess the whole renovation, rather than treating the charger as an isolated accessory.

Start with the energy you need to replace between trips and the hours the vehicle is normally parked at home. Those two facts often provide a more useful brief than the car’s maximum battery size.
Define the household’s charging routine
Record typical daily driving and any regular longer journeys. Note when the car arrives home, when it leaves and whether it is parked at home during solar-generation hours. Include the possibility of a second EV only if it is a realistic plan.
A car used for a short commute and parked overnight has different needs from one returning late after long daily trips. The same battery size can therefore lead to different charging requirements in different households.
The Australian Government’s EV charging equipment guidance explains that charging speed depends on both the charging equipment and the vehicle’s capabilities, along with operating conditions. Buying a higher-rated wall unit does not automatically make every vehicle charge at that rate.
Use energy demand rather than a full-battery habit
You may not need to replace the entire battery’s energy every night. Ask the vehicle manufacturer about recommended charging practices and limits for the model. Use the household’s actual driving pattern to establish the normal replenishment need.
Keep an illustrative calculation transparent
Suppose a vehicle uses an assumed 18 kWh per 100 kilometres and travels 40 kilometres in a day. That represents 7.2 kWh of driving energy before charging losses. The example helps define an ordinary day’s demand; it is not a consumption claim for every EV or a recommended charging limit.
Check the vehicle before selecting the charger
Provide the electrician or charging specialist with the vehicle model and relevant manufacturer information. Confirm the supported AC charging rate, connector arrangement and any requirements for the intended equipment.
If the vehicle has not yet been purchased, identify a realistic shortlist and ask what infrastructure can sensibly be prepared. Avoid installing expensive equipment on the assumption that every future vehicle will use the same features in the same way.
For two vehicles, discuss whether one shared point, two managed points or another arrangement suits the parking routine. The right answer depends on simultaneous use, available capacity and whether cars can easily swap positions.
Assess the home’s electrical installation
The electrician should inspect the relevant supply, switchboard and proposed circuit route. Existing equipment condition and the renovation’s other loads can influence the scope. Do not assume a spare space in the board means a charger can be added without further assessment.
The Australian Government’s guidance on charging at houses and strata buildings states that a dedicated charger needs installation by a licensed electrician and may require switchboard or supply changes. Those are project-specific possibilities, not an automatic requirement for every house.
Coordinate the charger with the switchboard assessment. Give the electrician the same appliance schedule used for the kitchen, hot water and air conditioning work.
Choose a location around the parked car
Draw the vehicle footprint, charging-port position and the route people use through the garage or carport. A charger near the switchboard may be inexpensive to connect but awkward to use if the cable cannot reach comfortably.
Consider how the car is normally parked. Reversing in may place the charging port differently from driving in, and a future vehicle may have its port elsewhere. Some flexibility is useful, but avoid a cable route that crosses a doorway or regular walking path.
Plan a place to store the cable and connector. The arrangement should keep them protected and easy to use without creating a trip or vehicle-impact hazard. Have the installer assess suitable mounting, exposure and protection for the actual location.
- Normal parking direction and vehicle position.
- Charging-port location and usable cable reach.
- Doors, paths and access to storage.
- Exposure to rain, sun and cleaning water.
- Potential vehicle impact.
- Future maintenance and equipment replacement.
Coordinate cable routes before finishes close
Ask the electrician to identify the practical route from the relevant electrical equipment to the charger. The route may pass through roof space, walls, external areas or ground works. The contractor determines suitable methods and requirements.
If a driveway or path is being rebuilt, discuss any required service route before concrete or paving is installed. Existing underground services must be identified and the work planned appropriately. Homeowners should not dig a trench based on a guessed straight line between the house and parking area.
Where the garage is being altered, keep the charger location coordinated with shelving, workbenches and doors. The guide to power point planning helps organise other garage uses so the new charging equipment does not compete with everyday access.
Consider load management in practical terms
Some charging arrangements can adjust demand in response to other household loads. Ask the electrician whether this is suitable for the project and which equipment supports the proposed method.
Have the operation explained with an ordinary example: the car is plugged in while the cooktop, oven and heating are in use. What happens to charging, and will the vehicle still receive the required energy before departure?
Also ask how the system behaves if communications fail or a controller is unavailable. A feature described as smart should have a clear operating explanation and an appropriate fallback, not simply a list of connected functions.
Match solar charging to when the car is home
Solar can contribute to charging when generation is available and the car is connected. If the vehicle is away throughout most weekdays, the benefit may be concentrated on weekends or other days at home. A financial model should reflect that routine.
Ask whether the proposed charger can respond to available solar surplus and what additional monitoring or control equipment is required. Compatibility with the existing solar system needs confirmation for the exact arrangement.
If a home battery is also planned, discuss priorities between household storage and vehicle charging. The guide to battery retrofits for existing solar explains why capacity, power and household use must be considered together.
Do not assume that adding a battery is necessary for solar charging or that charging an EV from a home battery is always the most economical arrangement. Ask for a comparison based on the actual tariff, equipment and usage pattern.
Choose controls that remain convenient
Useful features may include scheduling, access control, energy monitoring and load management. Rank them according to the household’s needs. A private garage may have different access-control requirements from an exposed shared parking area.
Ask whether charging can begin through a straightforward local action and what happens without internet service. Confirm whether ongoing subscriptions, accounts or third-party services are needed for any important feature.
If different household members use the charger, keep operation simple. A system that requires one person’s phone for every session can become inconvenient. Have the installer demonstrate the normal routine before sign-off.
Handle strata and shared-property approvals early
In apartments, townhouses and other shared properties, charging can involve common electrical infrastructure, shared areas and billing arrangements. Obtain the required owners corporation or body corporate approval before installation.
The Australian Government’s strata charging guidance notes that relevant laws are set by states and territories. The building’s own arrangements also matter. Do not assume another resident’s installation provides automatic approval for yours.
Ask who pays for electricity, how usage is measured and how future chargers will be accommodated. A private installation should not undermine a coordinated building-wide plan. Read apartment renovation rules alongside the specific charging proposal.
Build the full installed budget
A charger supply price may exclude circuit work, load-management equipment, switchboard changes, trenching and restoration. Ask for a site-assessed quotation identifying each component and any external approval dependency.
For illustration only, a project might allow AUD $1,200–$2,000 including GST for charging equipment, AUD $1,000–$2,000 for assessed electrical installation and AUD $500–$1,500 for route preparation or repairs. The combined illustrative allowance is AUD $2,700–$5,500.
These are invented planning ranges, not current Australian market prices. They exclude major supply upgrades, substantial switchboard work, unusual access and unconfirmed incentives. A simple installation may differ greatly from a detached garage reached across a finished driveway.
Use a like-for-like quotation comparison. Confirm the exact charger, cable arrangement, controls, commissioning and making good before deciding which offer is better value.
Estimate charging costs from energy and tariff
Charging cost depends on energy drawn and the applicable electricity price. Time-of-use tariffs, solar self-consumption and charging losses can change the calculation. A car’s driving consumption does not necessarily equal energy measured at the charger.
For an explicitly illustrative example, a session drawing 10 kWh from the grid at AUD $0.30 per kWh including GST costs AUD $3.00. At a different assumed tariff of AUD $0.45, the same measured energy costs AUD $4.50.
These figures are not current tariff offers or a forecast of daily driving cost. Use the actual electricity plan and vehicle data. If a supplier claims a precise annual saving, ask for the assumed distance, charging times, losses and comparison fuel price.
Do not assume vehicle-to-home capability
Some emerging charging arrangements can support energy flows beyond ordinary vehicle charging, but compatibility, approvals and availability are product- and location-specific. A standard home charger should not be assumed to provide household backup.
If bidirectional capability matters, ask for confirmation covering the exact vehicle, charger, electrical installation and applicable requirements. Treat an uncertain future feature as a separate consideration rather than a guaranteed benefit included in today’s purchase.
The renovation can still preserve sensible service routes while the technology choice is resolved. Ask the electrician what provision is useful without committing to unsupported equipment assumptions.
Plan commissioning and household handover
The installer should complete the required testing, documentation and any approval steps for the work. Ask for the selected charging limits, schedules and load-management settings to be recorded.
Have the normal connection and storage routine demonstrated safely. Know how to identify a fault, stop a session through the intended controls and contact the installer. Do not open the charger or attempt electrical repairs yourself.
Keep the product warranty, installation documents and account information in an accessible household record. If the property will be rented or sold later, clear instructions make the equipment easier to manage.
Check use with the garage fully occupied
Before finalising the position, consider the garage with the car, bicycles, bins and stored equipment in place. A charging cable that reaches easily in an empty garage may become awkward when everyday storage returns. Check access to the connector with the vehicle doors open and allow a practical place for the cable when charging is finished.
For an outdoor position, consider how the household connects the vehicle during rain and darkness. Suitable lighting, a clear walking surface and protected equipment storage can make daily use easier. The electrician still determines the appropriate electrical equipment and installation for the exposure.
Separate infrastructure preparation from equipment purchase
If the EV purchase is several years away, ask whether the current renovation should provide an assessed route and other useful preparation rather than installing a charger immediately. Product features and vehicle choices may change. Document what has been prepared and what remains necessary before use. This preserves practical options without describing an unfinished provision as a ready-to-use charging installation.
Choose a charger that fits the renovation and routine
A useful home charging installation supplies the energy the household needs within the available parking time, without awkward cables or unsupported electrical assumptions. It should remain accessible, understandable and compatible with the chosen vehicle.
Plan the route before finishes are complete, coordinate all new loads and compare complete proposals. Put the work into the renovation timeline so charging becomes a considered part of the home, rather than a difficult addition after the garage is finished.
