Can I get a 22 kW charger at home?
A 22 kW AC charger normally needs a suitable three-phase electrical supply and a vehicle that can accept three-phase AC charging.
Most UK homes have a single-phase supply, so a 22 kW charger is not usually available without a three-phase supply upgrade or a property that already has three-phase power.
What your installer will check
Your installer may check:
- whether the property has single-phase or three-phase supply
- available supply capacity
- main fuse or service head details
- earthing arrangement
- consumer unit and circuit design
- cable route and installation method
- whether the vehicle can actually charge at 22 kW AC
Vehicle compatibility matters
Some vehicles cannot accept 22 kW AC even when connected to a 22 kW charge point. The vehicle's onboard charger sets the maximum AC rate it can take.
For example, a vehicle with a 7 kW onboard AC charger will not charge at 22 kW from an AC charge point.
When 22 kW makes more sense
22 kW charging is more common for:
- commercial premises
- fleet sites
- workplaces
- sites with existing three-phase supply
- shared charging locations with suitable electrical capacity
