Most home EV charger installations in the Hills District take between two and four hours from the time we arrive to the time we leave. That’s the honest answer. But what sits inside that window — and what can push a job longer — is worth understanding before you book.
Here’s what’s actually involved, based on jobs we’ve completed across Castle Hill, Rouse Hill, Kellyville, Kenthurst, and the surrounding Hills suburbs.
The Straightforward Installation
The quickest EV charger installations are those where the switchboard has spare capacity, the garage is close to the board, and access through walls or ceiling is clean. In these situations — a modern home, single-phase supply, charger going in near the meter board — two hours is realistic. We run the dedicated circuit, mount the charger, make all connections, test the installation end-to-end, and issue the Certificate of Electrical Compliance.
When the Job Takes Longer
Two things extend installation time more than anything else: cable run complexity and switchboard condition.
Cable run distance and access
In a double-storey home where the garage is on the opposite side of the building from the switchboard, running cable the correct and concealed way takes time. We recently completed a Tesla Wall Connector installation in Rouse Hill exactly like this — double-storey home, garage at the far end of the house from the switchboard. Getting the cable through the house properly, without leaving surface-run conduit across ceilings or walls, added time to the job. But the result was a clean installation with no visible cabling. That’s the standard we hold.
Single-storey homes with a garage adjacent to or close to the meter board are straightforward. The further the distance — and the more obstacles between the switchboard and the charger location — the longer the cable run takes.
Switchboard capacity and condition
Before any EV charger circuit can be connected, we assess the existing switchboard. If the board has spare capacity and is in good condition, we connect directly and proceed. If it’s an older board without safety switches on every circuit, or if it’s already running close to capacity, a switchboard upgrade becomes part of the job.
This isn’t a problem — it’s the right thing to do — but it adds time and cost that homeowners should be aware of upfront. A good electrician identifies this during the quote, not on the day. We always assess switchboard capacity as part of the quoting process so there are no surprises on installation day.
What About App-Connected Chargers?
Smart chargers — like the Ocular, which connects to a smartphone app for monitoring and scheduling — add a configuration step to the installation. Once the charger is wired and tested, we connect it to your home network and walk you through the app setup so you leave the day knowing exactly how to use it. We recently installed an Ocular charger for a homeowner in The Gables and had it connected and configured without adding significant time to the job overall.
If you’re planning to use your EV charger with a solar system to charge from excess solar generation — which is increasingly common in the Hills District — this is worth discussing during the quote. Smart chargers like the Zappi are designed specifically for this and are set up slightly differently than a standard installation.
What Affects Your Specific Installation Time
| Factor | Impact on Time |
|---|---|
| Switchboard close to garage | Faster |
| Switchboard far from garage / opposite end of house | Slower |
| Double-storey with concealed cable run | Slower |
| Switchboard needs upgrading | Longer — upgrade quoted separately |
| Smart charger requiring app configuration | Small additional time |
| Simple single-phase, modern board | 2–3 hours typical |
What You Can Do Before Installation Day
A few things that keep the job moving cleanly:
- Know where your switchboard is located and make sure it’s accessible
- If your home was built before 2000, it’s worth checking whether your switchboard needs upgrading before installation day — it’s better to know upfront than discover it on the day
- If you’re purchasing your own charger, have it on-site before we arrive
- Let us know in advance if you have solar — it may affect the charger recommendation
What Happens at the End
Every EV charger installation we complete is signed off with a Certificate of Electrical Compliance, as required under NSW law. We test the installation fully before we leave, walk you through the charger operation, and clean up the site. The job isn’t done until you’re satisfied with how it looks and how it works.
