Do I need a home wallbox to own a Chinese EV?
Updated 2026-05-186 min read
Home charging is the single biggest determinant of EV ownership economics.
01
Wallbox vs granny cable
Wallbox 7 kW: adds ~45 km per hour, full charge overnight.
3-pin 'granny cable': adds ~10 km per hour, best for topping up only.
02
Installation cost UK/EU
UK: £800–1,400 supply and fit for standard install; grants available in Scotland (up to £400) and for renters (OZEV grant).
EU: €900–1,500 depending on country and installation complexity.
03
Cost economics
Home electricity ~£0.25/kWh UK average; overnight tariffs ~£0.07.
Public DC ~£0.65–0.80/kWh at fast chargers.
