🔌 So, You’ve Bought an EV — Now Comes the Charger

You’ve taken the leap. You’re driving an electric vehicle, enjoying the silence and skipping petrol stations. But when it comes time to install a home charger… things get complicated, fast.

Suddenly, you’re faced with unfamiliar terms:
Type 1 vs Type 2, tethered vs untethered, OZEV grants, load balancing, single-phase vs 3-phase, smart features, and — perhaps most unexpectedly — a wide range in pricing and performance.

Let’s break it down.


⚠️ The Hidden Traps People Don't Talk About

1. Charger Compatibility Isn’t Always Universal

Not all EVs are created equal — and not all chargers work seamlessly across different makes and models.
Trap: You might install a charger that technically works, but not at the optimal speed or efficiency for your car.

Flare Tip: We assess your EV type, cable spec, and future vehicle plans before recommending a charger.


2. Tethered or Untethered? That “Small Detail” Matters

Tethered = built-in cable
Untethered = bring your own cable
Tethered is often neater and quicker — but less flexible if your next EV uses a different plug type.

💡 Think long term. If you’re planning to upgrade cars often or install at a shared property, untethered may be safer.


3. Smart Features Are Not Just Fancy Extras

Some chargers offer timed charging, solar integration, remote scheduling, or even tariff syncing. These aren’t gimmicks — they can dramatically reduce your bills.

Smart charging systems let you plug in now, and charge later — when energy is cleanest and cheapest.


4. Installation Isn’t One-Price-Fits-All

A “£899 install” might sound appealing — until the installer charges £400 extra for the cable run or consumer unit upgrade. Surprise extras are common.

👷 We give you upfront pricing based on real site conditions — not vague estimates.



💸 The Real Cost of EV Charging
