Welcome. Others will chime in as I do not have a home charger and live in US. There are a couple of UK members. I just use available public chargers but am jealous of those who have installed charger at home or work.
First, you all are on 220v so I don't know how this affects our answers from the US.
- the typical charger that comes with cars in US have a US plug and only charges at 110v or 1.2 KwH, so a full charge takes 18+ hours. Not sure what your provided charger can do. Hopefully, 220v. If so, then full charge time will be as you said, 4-5 hours.
- any licensed electrician can install.
- depends on ability to use 220v supply.
- no known issues using home charger in US.
- others can opine, dunno.
Yes, when I visited UK on holiday, was impressed with roll out of charging stations. Even the London black taxis are to be all electric. Depending on your driving needs, perhaps you, like me, can get along without putting in a home charger. An 8 hour overnight charge using provided charger could work assuming it works on 220v (BIG QUESTION). You must have a dedicated line though or nothing else running overnight.
Enjoy the ride.
