EV Charger Installation at Home: What UK Homeowners Need to Know
With electric vehicle adoption accelerating across the UK, home charging is the most convenient way to keep your EV powered. Here's what you need to know before installing a charge point.
Do You Need a Dedicated Circuit?
Yes. A home EV charger requires a dedicated circuit from your consumer unit. A qualified electrician must assess whether your existing installation can support the additional load — typically 7kW (32A) for a standard home charger.
Choosing the Right Charger
The most common home installation is a 7kW tethered or untethered wall-mounted unit, which provides roughly 25–30 miles of range per hour of charging. Consider:
- Tethered vs untethered — tethered units have a fixed cable; untethered accept your own
- Smart connectivity — schedule charging during off-peak electricity tariffs
- Compatibility — ensure the unit works with your vehicle
What Affects Installation Complexity?
Several factors influence how straightforward an installation will be:
- Distance from the consumer unit to the preferred charge point location
- Existing electrical capacity — whether your installation can support a dedicated circuit without upgrade
- Cable routing — internal walls, external runs, and groundworks where required
- Charge point specification — tethered vs untethered, smart features, and manufacturer requirements
