As electric vehicles become increasingly common across Castle Hill, Kellyville, Baulkham Hills and the rest of the Hills District, the question we’re hearing most is: how much is this actually going to cost?
The short answer: $1,500–$3,000 for most homes, but the range is wide and there are a few things that drive it up. Here’s an honest breakdown.
What Affects the Cost
1. Your Switchboard
The single biggest variable. A modern switchboard (post-2000, with RCD protection) makes installation straightforward. An older switchboard — particularly those in homes built before 1980 — may need upgrading before a charger can be safely connected, adding $800–$2,000 to the job.
Roughly 35–40% of Sydney homes built before 1980 require some switchboard work for an EV install. A site assessment will tell you before you commit.
2. Cable Run Distance
The distance from your switchboard to where you want the charger matters. Under 10 metres is easy. A 25-metre run through the house (common in terrace homes or when the garage is far from the board) significantly increases material and labour costs.
3. Charger Type
A standard 7.4kW single-phase charger suits most Hills District homes. Three-phase chargers (faster, but requiring three-phase power) cost more to install. As at 2025, most Hills District homes have single-phase — but it’s worth checking before you buy a charger.
4. The 2025 NSW Demand-Response Requirement
This one surprises people. From 2025, any EV charger above 20 amps single-phase installed in NSW must be demand-response capable. A standard 7.4kW charger runs on a 32-amp circuit — so almost every new home install is affected.
In practice: your charger needs to be OCPP-capable (a smart charger that can communicate with the grid). Older “dumb” chargers don’t qualify. This isn’t optional — it’s a legal requirement for new installs.
Typical Costs — Hills District Homes
| Scenario | Typical Cost |
|---|---|
| Modern home, short cable run, no board work needed | from ~$1,500 |
| Standard install, up to 10m run, no board upgrade | $1,500–$3,000 |
| Long cable run (10–25m) or minor board work | $2,500–$4,000 |
| Older home with switchboard upgrade needed | $3,000–$5,000+ |
All figures are for supply and installation of a standard 7.4kW OCPP-capable charger. Hardware costs vary by brand and model.
Are There Any Rebates?
The NSW state EV charger rebate ended in January 2024. However, some local council grants (ranging from $250–$5,000) are available for Hills District households and strata properties — worth checking with your council before you book.
Federal DRIVEN rebates of up to $2,500 are available for eligible businesses.
Why Get a Site Assessment First
The only way to get an accurate quote for your home is a site assessment. It takes 30–60 minutes, costs nothing (no call-out fee), and means you get a fixed price before any work starts — not a “from” price that blows out when the electrician opens your switchboard.
