EV Ready Before You Even Buy the Car: The Cheap Provisions to Make During Any Reno

How do you make a home EV ready before you even own an EV? By spending small money while the walls and trenches are already open: a conduit run from the switchboard to where the car will park, spare space on the board, and supply with enough headroom to add a charger later. Done mid-renovation these provisions cost a fraction of what the same work costs as a standalone job years later.

⚡ Quick Answers: EV ready renovations

• What is the single cheapest provision? Empty conduit from the switchboard to the garage or carport while walls are open or trenches are dug. Pulling cable through later is easy; cutting into finished walls is not.
• Do I need three phase power for an EV? Not necessarily. Plenty of Sydney homes charge comfortably on single phase, but if you are upgrading supply for other reasons anyway, it is the moment to consider a three phase upgrade.
• Will an EV charger overload my house? Only if nobody checks the numbers. Maximum demand is the calculation that answers it, and load management can solve most tight cases.
• Does adding a charger involve my electricity network? Sometimes. A significant load increase can trigger a Notification of Service Work to Ausgrid or Endeavour Energy.
• What does getting EV ready cost during a reno? Usually a minor line item: conduit, a bigger board, and an hour of planning. The exact scope comes out of a site assessment.

1. Run the conduit while everything is open

The most expensive part of many EV charger installs is not the charger, it is the cable route: getting a heavy cable from the switchboard to the parking spot through finished walls, ceilings or paving. During a renovation that route is sitting wide open. A length of conduit with a draw wire, from the board to the garage wall, costs very little and turns a future install into a simple pull-and-connect job.

If your renovation includes any trenching for services, run a spare conduit to the carport at the same time. Our post on what the Wiring Rules mean for your renovation covers the other decisions worth making while the walls are open.

2. Leave room on the switchboard

A dedicated EV charging circuit needs physical space on the board for its protection. If your renovation already includes a switchboard upgrade, ask for spare ways rather than a board sized exactly to today's circuits. The difference in cost is small; the difference when the charger arrives is a connection job instead of a second board upgrade.

3. Check your maximum demand headroom

Every home has a supply capacity, and every appliance you add eats into it. Maximum demand is the calculation electricians use to work out whether the supply can take another major load, and an EV charger is one of the biggest loads a house can gain. Get the number checked during the reno, while fixing a shortfall is cheapest. You can get a feel for it yourself with the maximum demand calculator on our free tools page, and for apartment buildings and tight cases, power logging measures what your supply really has left.

4. Decide the single versus three phase question once

Single phase charging suits most commuting patterns: overnight charging adds plenty of range even at modest power. Three phase charges faster and future-proofs a household heading all-electric, but it is a supply upgrade with real cost. The renovation is the right time to decide, because a three phase charger upgrade done later repeats work your reno could have included. If you are weighing it up, our guide to what changes in a three phase upgrade shows what the job involves end to end.

5. Plan around where the car actually parks

Chargers work best short and close: mount the unit near the car's charge port side, keep the cable run from the board as direct as possible, and think about a second conduit if a two-EV future is plausible. Off-street parking behind the house, a detached garage or a long driveway all change the answer, and they are all cheaper to solve during landscaping than after it.

6. Sort the metering while the sparky is there

Charging overnight on the right tariff is where EV running costs get genuinely cheap. A smart meter upgrade during the renovation sets you up for time-of-use charging later.

Why it's Level 2 ASP work

Adding a large load can push a home past what its existing connection was assessed for. Under the Service and Installation Rules of NSW, a significant load increase can trigger a Notification of Service Work to your distributor, and any resulting power supply upgrade, consumer mains work or three phase conversion is Level 2 ASP territory. Our post on when a load increase triggers a NOSW explains the trigger points, and you can check your network area in seconds with our postcode checker to see whether Ausgrid or Endeavour Energy covers your street.

How High Demand Electrical helps

We fold EV readiness into renovation electrical work so it costs provisioning money, not retrofit money: conduit runs and draw wires while walls are open, boards sized with spare ways, maximum demand checked against your real plans, and the supply upgrade or NOSW handled in-house because we are Level 2 accredited. When the car eventually arrives, the install is a short visit instead of a project.

EV ready home FAQs (Sydney)

Is it worth getting EV ready if I have no plans to buy an EV?

If you are renovating anyway, yes. Conduit and board space cost little, and buyers increasingly ask about EV readiness, so the provisions carry value even if you never plug a car in.

Can I just use a normal power point in the garage?

You can trickle charge from a standard outlet, but it is slow and the circuit needs to be in good condition. A dedicated circuit is the safe, fast option, which is exactly what the conduit provision makes cheap.

How do I know if my supply has enough headroom?

A maximum demand assessment answers it. Try the calculator on our free tools page for a first pass, then have it confirmed on site.

Does an EV charger need network approval?

The charger itself does not, but the load increase it creates can require a Notification of Service Work, and some larger or managed setups involve the distributor.
