What changes the cost of installing an EV charger?

November 07, 2026

Five things set the price: the charger, how far the cable has to run, how it gets there, the state of your switchboard, and whether your supply needs work. That's why you won't find a number from us here. Two houses on the same street can need very different jobs, so we come and look first, then give you a fixed price in writing.

If you want a rough idea first, Tesla's Australian support page gives a range for a straightforward Wall Connector install, and the NSW Government gives one for switchboard upgrades. They aren't our prices. Tesla's lists extras separately, and NSW's covers the switchboard only.

What goes into the price?

1. The charger

Prices vary with the brand, and with features like solar charging. Sometimes you don't need one: if you drive short distances, a power point may do. If you've already bought one, we'll check the model and fit it. Here's how to choose.

2. How far the cable has to run

This can make a big difference. Tesla lists a long cable run from the switchboard to the charger as a typical extra. A charger is usually half a day for us, and a long cable run can take most of the day.

3. How the cable gets there

Tesla also lists concealed cabling, trenching or digging for an underground run, and a stand or special mounting as typical extras. A garage with the switchboard on the same wall is a simple job. A carport across the yard isn't.

Stay out of the roof space and sub-floor. You don't need to go up or under to work any of this out. If your house was built or renovated before 1990, NSW Government advice is that it's likely to contain asbestos. So don't drill or cut walls, eaves or switchboard panels until you know what they're made of. In a home built before 1980, stay out of the roof space and sub-floor until testing rules out loose-fill asbestos insulation. Don't touch cables or insulation.

4. Your switchboard

A charger needs its own circuit, so we check your switchboard first. The NSW Government says an EV charger may require an upgrade, and flags homes 25 years or older with the original panel or fuse box. Not every board needs replacing, but old fuse boards usually do. Tesla lists a switchboard upgrade and an extra sub-panel as typical extras. Here's how to tell if yours can stay.

5. Your supply

Ausgrid says that if a licensed electrician finds the supply must be upgraded, that needs a connection application. It also says a home over 20 years old that hasn't been rewired may need a meter upgrade, which goes through your retailer. Moving to three-phase is the big one, and most people don't need it.

How can you keep the cost down?

Ask if a smaller job will do. A 15 A power point on its own circuit is a smaller job than a wall charger, and it may be enough if your portable charger takes 15 A.
Don't buy more charger than your car can use. Check its maximum AC rate first.
Be flexible on where it goes. Closer to the switchboard usually means a shorter cable run.
Ask about a lower setting. Tesla says the Wall Connector can be installed on a lower-rated circuit breaker when power is limited, which may help where a switchboard or supply is tight.
Do it before the car arrives. Tesla recommends installing before delivery, and says finding an installer and booking can take up to two weeks. Booking early means you aren't stuck taking the first date going.

What should a quote show?

The NSW Government suggests getting quotes from licensed electricians with EV charger experience. To compare them fairly, check each one covers:

The charger, any switchboard work and the installation, as separate lines.
The cable route and length, and whether it's hidden.
Who deals with Ausgrid, and whether any supply or meter work is extra.
The Certificate of Compliance for Electrical Work (CCEW). Building Commission NSW says the electrician who tests the work must submit it within seven days of the test.
The contractor's licence number.
Whether the price can change after you say yes.

Ours lists the charger, any switchboard work and the installation as separate lines. The price we quote is the price you pay. Once you say yes, the price doesn't move. If we open something up and find a real surprise, we stop, show you, and quote it before we go any further. A 30% deposit locks in your installation date, and when it's done, you get the certificate.

Is there a rebate for a home EV charger?

We couldn't find a federal rebate for households, as at 7 November 2026, and Evnex's Australian rebate page lists none. NSW's loan page says wall chargers can't be combined with the federal or NSW certificate schemes that discount some other upgrades. But these are worth checking:

NSW Home Energy Saver discounts. NSW has announced discounts that list Level 2 EV chargers, for lower-income households and concession card holders. Applications hadn't opened as at 7 November 2026. If you might qualify, apply for the discount before any loan.
NSW Home Energy Saver loans. Zero-interest loans for eligible owners and landlords, with an income limit. They run through Brighte and Plenti, and each keeps its own list of approved suppliers. We're not on those lists at the moment, so check before you book an installer if you want one of these loans.
Your council. Randwick City Council lists a household rebate that includes EV chargers. Northern Beaches Council's page doesn't. Check yours.
Green loans. The NSW Government says the federal Household Energy Upgrades Fund offers low-interest loans through participating lenders, which may cover home chargers.
A novated lease. If your car is on one, ask your provider how a charger is treated.

Want an actual number for your house? Book a time for us to look. You get the quote in writing, line by line. Once you say yes, the price doesn't move. If we open something up and find a real surprise, we stop, show you, and quote it before we go any further. We work across the Northern Beaches, the North Shore, the Eastern Suburbs and the Inner West.

Common questions

Can you give me a price over the phone?

Not a fair one. Most of what moves the price is at your house, so we look first. If you send photos of your switchboard and where you'd like the charger, we can tell you what we're likely to be looking at.

How long does an install take?

Usually half a day. A long cable run can take most of the day.

What will it cost to run?

That depends on your electricity plan. Ausgrid says charging in off-peak hours saves money on a time-of-use plan, and that some retailers offer EV tariffs. It also says charging from your own solar costs nothing extra. You do give up any feed-in credit for that power.

Do you do the whole job?

Yes. We fit the charger, do the switchboard work and deal with Ausgrid. If a Level 2 service provider is needed, we tell you first and organise them. See our EV charger page.
