If you’ve recently bought (or are planning to buy) an electric vehicle, one of the next big decisions is choosing the right home EV charger.

With so many makes, models, and smart features available, it can be hard to know which charger suits your car, your home, and your budget.
Here’s a simple guide to help you make the right choice — and stay safe, compliant, and future-ready.

1. Check Your Vehicle’s Charging Capability
Every EV supports different charging speeds.
Most UK homes are limited to single-phase power, which means your charger will usually be up to 7.2 kW.
Before buying, check your car’s maximum AC charging rate:
3.6 kW (slow)
7.2 kW (fast — standard for most UK homes)
11 kW or 22 kW (requires three-phase supply, uncommon in domestic properties)
⚙️ Tip: Even if your car only supports 3.6 kW now, installing a 7 kW charger prepares your home for future EVs.

2. Decide Between Tethered and Untethered Chargers
Tethered (Cable Attached)
Comes with a built-in charging lead
Quick and convenient — just plug in
Cable length typically 5–7 metres
Slightly tidier and easier to use daily
Untethered (Socket-Only)
No fixed cable — use your vehicle’s own lead
Cleaner look and more flexible
Compatible with both Type 1 and Type 2 connectors
Ideal if you change cars or lease vehicles frequently
🧰 Most new EVs use a Type 2 connector, which is now the UK standard

3. Choose Between Standard and Smart Chargers
A smart charger connects to Wi-Fi or Bluetooth and gives you more control over your charging:
✅ Schedule charging during off-peak hours to save money
✅ Monitor usage and costs via a smartphone app
✅ Integrate with solar panels or smart home systems
✅ Automatically adjust charging speed based on household load
While smart chargers cost slightly more, they often pay for themselves through energy savings and convenience.

4. Consider Where You’ll Mount the Charger
Location matters for both safety and usability.
Common options include:
-Garage walls (indoor protection and security)
-External house walls near your driveway
-Free-standing posts for car parks or detached garages
Your NAPIT-registered electrician will advise on the safest and neatest cable route, ensuring compliance with BS 7671 wiring regulations.

5. Think About Future-Proofing
EV technology is evolving quickly. To stay ahead, consider:
-7 kW or higher output for faster charging
-Load balancing to protect your home’s supply
-Solar integration if you plan to install panels
-Dual chargers if your household may own multiple EVs
Installing with a professional now can save you costly upgrades later.

6. Typical Costs and Installation Factors
Expect to pay around £600 – £1,200 for installation, depending on:
-Cable run distance from your consumer unit
-Charger model and smart features
-Any required electrical upgrades (e.g. RCD, consumer unit)
Some homeowners may qualify for government EV Chargepoint Grants, especially renters and flat owners.

7. Always Use a NAPIT-Registered Electrician
EV charger installation involves high-power circuits, earthing checks, and RCD protection — so it’s not DIY work
A NAPIT-registered electrician will:
-Ensure your system meets Part P and BS 7671 regulations
-Notify your DNO (Distribution Network Operator)
-Provide a Certificate of Compliance for your records
That means your installation is safe, efficient, and fully insured.
