Why You Need a Home EV Charger (And Why Right Now)
Let me be straight with you: if you own an electric vehicle in South Africa and you’re still relying on public chargers, you’re literally throwing money away. Here’s what most EV owners discover within their first few months:
The Public Charging Reality Check
- 🚗 Detours waste time: Average 15-20 minutes extra per charging stop
- 💸 Costs are brutal: R5.50/kWh at fast chargers vs R1.50/kWh at home off-peak
- ⏰ Queues during load shedding: Sometimes 30+ minute waits
- 😤 Broken chargers: Roughly 15-20% are out of service at any time
- 🔌 Incompatibility issues: Not all chargers work with all payment methods
What Home Charging Actually Looks Like
Compare that nightmare to this: You pull into your garage at 6 PM. Plug in your car. Go inside, have dinner, watch TV, sleep. Wake up at 7 AM to a fully charged vehicle. Every. Single. Day.
Real Owner Experience: Cape Town Homeowner
“I was spending R650-800 per month on public fast charging for my daily 60km commute. After installing a home charger, my monthly cost dropped to R240. That’s R6,000+ saved in the first year alone, and the charger paid for itself in 3.5 years. Best decision I made.”
— Michael T., BMW i3 owner, Constantia
The Numbers Don’t Lie: What You’ll Actually Save
Let’s do some real math based on actual South African prices (December 2025):
Annual Charging Cost Comparison

Frequently Asked Questions
Can I install an EV charger myself to save money?
Short answer: No, it’s illegal and dangerous.
South African law requires all fixed electrical installations to be performed by a licensed electrician (Electrical Installation Regulations, 2009). DIY installation:
- Voids all warranties on the charger
- Violates insurance policy conditions
- Creates serious fire and electrocution risks
- Is punishable by fines up to R100,000
- Makes your home uninsurable
Professional installation pays for itself through: Guaranteed safety, warranty protection, insurance validity, proper load calculations, and certified compliance.
Will my electricity bill skyrocket?
Reality check: Your bill will increase, but far less than you’d spend on petrol.
Real numbers (15,000 km/year driving):
- Electricity cost increase: R280-R400/month (off-peak charging)
- Petrol you’re no longer buying: R1,925/month
- Net monthly saving: R1,525-R1,645

What about load shedding?
Smart solutions exist:
- Scheduled charging: Set charger to run during your load shedding schedule gaps
- Battery backup integration: Charger can draw from home battery during outages
- Solar + battery: Charge independent of Eskom completely
- Opportunity charging: Top up whenever power is available
Reality: Most EV owners charge overnight (10 PM – 6 AM) when load shedding is less frequent. A 7.4kW charger adds ~40km range per hour, so even partial charging sessions provide plenty of range.
I live in a complex/estate. Can I still install a charger?
Yes, but you need approval.
Process:
- Get quote and installation plan from us
- Submit to body corporate/trustees with technical specs
- Address any concerns (we can attend meetings to explain)
- Obtain written approval
- Schedule installation
Success rate: ~95% of applications approved. Most objections are due to aesthetic concerns (easily addressed) or fire safety worries (we provide certificates).
We help with: Application letter templates, technical documentation, answering trustee questions, suggesting compromises.
Can I use my charger with any EV brand?
Yes! All chargers are universal.
In South Africa (and Europe), the Type 2 connector is standard. Every EV sold here either has:
- Native Type 2: BMW, Audi, Jaguar, Mercedes, Volvo, etc.
- Type 1 with adapter: Older Nissan Leaf models (adapter included with car)
- Tesla with adapter: All Tesla vehicles include a Type 2 adapter
One charger works for: Your current EV, future vehicle upgrades, guest vehicles, multiple household EVs.
What if I sell my house?
Good news: EV charger adds property value.
Options when selling:
- Leave it installed (recommended): Increases property value R15,000-R30,000. Major selling point for EV owners and future-conscious buyers
- Include in sale: Add charger value to asking price
- Remove it: Technically possible but requires electrical work to make safe. Usually not worth the effort
Estate agents report: Homes with EV chargers sell 15-25% faster in major metros and command 2-3% price premiums.
