Running an EV Charger Installation Business in Australia
The client wants a charger on the garage wall by Friday. You quote the charger and the cable run. Then you open the switchboard and it's a 1980s meter box with no spare positions, dodgy wiring, and an upgrade that'll cost $1,800. The client says "you didn't mention that." This is EV charger installation — a fast-growing niche with genuine demand, but one where scope definition at the quote stage is everything.
What an EV charger installation business looks like
What EV charger installers deal with
Scope creep — switchboard upgrades swallow the margin
The most common EV charger dispute is a switchboard upgrade the client didn't expect. Clients see "EV charger installation" as the whole job. Operators who quote the charger without inspecting the switchboard first set up the conversation where the client feels ambushed by a surprise variation.
The fix is a site assessment before quoting. Inspect the switchboard, confirm spare capacity, check the earth and neutral bonding, and quote the full job — charger plus any switchboard work — in one document as distinct line items. Clients who understand the breakdown accept it. Clients hit with it after the fact don't.
Compliance documentation — three certificates, not one
Every EV charger installation needs: an Electrical Safety Certificate (Certificate of Compliance for Electrical Work in most states), grid connection notification to the local network operator where required, and the manufacturer's commissioning documentation for warranty purposes. Operators who issue the ESC and walk away are leaving the network notification and manufacturer commissioning incomplete.
Build all three into your job completion checklist inside your job management system. The job isn't closed until all three documents are issued. Missing documentation is a liability when the charger is involved in an insurance claim or a vehicle fault.
Residential vs commercial — different products, different compliance
A residential Level 2 wall charger is a straightforward install. A commercial car park with 10 bays, load management hardware, network connectivity, and a charging network agreement is a project. Operators who price commercial installs off residential rates lose money. And operators who install commercial hardware without understanding the network operator's technical requirements for grid-connected charging infrastructure create compliance issues. Know before you quote which type of job you're pricing.
Where EV charger installers lose compliance protection and margin
| Stage | What You Need | What's Actually Happening |
|---|---|---|
| Quoting | Site assessment before quoting. Switchboard inspection included. Charger install + switchboard work quoted as separate line items. Compliance documentation listed in scope. | Quote sent over phone based on description. Switchboard not inspected. Client gets a variation on the day. Dispute begins. |
| Job Management | ESC, network notification, and manufacturer commissioning documented. Photos of install. All three certificates issued before job closed. | ESC issued. Network notification forgotten. Manufacturer commissioning not done. Warranty claim rejected 18 months later. |
| Invoicing | Invoice on completion. Variations documented and approved before work commenced. Compliance docs attached to invoice. | Variation done verbally. Client disputes the price. Invoice delayed while negotiating. |
| Payments | 50% deposit on booking for residential. Progress claims on commercial. Balance on completion with docs attached. | Full payment requested after completion. Client delays while reviewing. Cashflow pressure on a high-material-cost job. |

Not always, but frequently. A Level 2 AC charger draws significant load. If the switchboard is at capacity or lacks spare positions, an upgrade is required. Always quote charger and switchboard as separate line items so clients understand the breakdown — it prevents the surprise-variation conversation on the day.
Every install requires an Electrical Safety Certificate, network operator notification where applicable, and the manufacturer's commissioning documentation. Build all three into your job completion checklist. Missing documentation creates liability when a charger is involved in an insurance claim or vehicle fault.
For publicly accessible or managed commercial charging, a network partnership (Chargefox, Evie, NRMA) changes the commercial model — you install the hardware, they manage billing. Clarify at quote stage whether the client wants private or networked charging. They require different hardware and different compliance processes.
