EV Electrical Readiness – Melbourne
Why This Matters
Most homes aren't designed for the electrical demands of EV charging. Installing a charger without preparation can overload your system and create safety risks.
- Continuous high electrical loads
- EV charger demand
- Modern energy usage patterns
Common Problems We Solve
EV charger installation rejected
Purchased EV charger but installer refused to connect it due to insufficient switchboard capacity. Now facing unexpected upgrade costs before charger can be used.
Switchboard can't handle continuous load
Home's electrical system designed for intermittent loads. EV charger runs for hours at high power, exceeding switchboard capacity and creating safety risk.
Unclear upgrade requirements
Multiple quotes with conflicting advice about what's needed. No clear understanding of costs or whether existing system can support EV charging.
Unexpected costs after EV purchase
Bought EV assuming home was ready for charger. Discovered electrical system needs $3,000+ upgrade. Should have assessed readiness before EV purchase.
Why This Matters in Melbourne
EV adoption is growing rapidly in Melbourne's middle-ring suburbs. Many homes in Hawthorn, Kew, Camberwell, and Glen Iris have off-street parking but outdated electrical systems. Inner-city apartments face additional challenges with shared meters and body corporate approvals. Older homes (pre-1990) almost always require switchboard upgrades before EV charger installation.
Standards & Requirements
- AS/NZS 3000:2018 — Load calculations required for continuous high-power loads
- EV chargers typically draw 7.4kW (32A single-phase) or 11kW+ (three-phase)
- Dedicated circuit required — cannot share with other appliances
- RCD protection mandatory on EV charger circuit
- Switchboard must have spare capacity for continuous load
- Supply cable from street may need upgrade if insufficient capacity

20 minsInspect switchboard size, available spare ways, existing circuit loading, and main switch rating. Determine if capacity exists for EV charger circuit.
Load Calculation & Analysis
15 minsCalculate total connected load, assess diversity factor, determine maximum demand, and verify if EV charger can be added within safe limits.
Charger Location Evaluation
15 minsAssess proposed charger location, measure cable run distance, identify routing path, check for obstacles, and evaluate installation complexity.
Supply Cable & Meter Check
10 minsInspect incoming supply cable size and condition, check meter capacity, assess if supply upgrade needed from distributor.
Written Report & Recommendations
15 minsPrepare detailed report with findings, upgrade requirements (if any), cost estimates, and recommended next steps for EV charger installation.

Frequently Asked Questions
Should I get this assessment before buying an EV?+
Strongly recommended. Knowing your home's readiness and upgrade costs (if any) before EV purchase prevents unexpected expenses. Assessment takes 1-2 hours and provides clear cost picture.
What information do I need to provide?+
Property address, whether you have off-street parking, preferred charger location, and EV model (if already purchased). Photos of your switchboard helpful but not required.
Do you assess apartments and townhouses?+
Yes — but apartments may require body corporate approval and shared meter assessment. Townhouses typically simpler if you have dedicated meter and parking. We assess both scenarios.
How long does the assessment take?+
Typically 1-2 hours including switchboard inspection, load calculations, charger location assessment, and report preparation. You receive written report same day or next business day.
Do you install the EV charger?+
We focus on electrical readiness — preparing your home so any charger can be safely installed. We do not sell or install charger units. Once system is ready, any licensed installer can connect your chosen charger.
What if my home needs upgrades?+
Assessment report clearly explains what's needed and why. We provide fixed-price quotes for required work (switchboard upgrade, dedicated circuit). You decide whether to proceed. No obligation.
Can I use the report with any charger installer?+
Yes — report is independent and can be provided to any charger installer or electrician. Shows your home is ready (or what's needed to make it ready).
Is this assessment required by law?+
Not legally required, but strongly recommended for safety and compliance. Many homes — especially pre-1990 — do not have capacity for EV charger without upgrades. Better to know before purchasing charger.
What's included in the assessment price?+
Switchboard capacity assessment, load calculations, charger location evaluation, supply cable check, written report with recommendations, and upgrade cost estimates (if needed). No hidden fees.
How much do upgrades typically cost?+
Switchboard upgrades: $950-$4,500. Dedicated circuit installation: $800-$1,500. Supply cable upgrades (if needed): varies by distributor. Assessment report provides specific pricing for your situation.
