Home EV charger question

Just sorting out the installation of the EV charger for my Skoda Enyaq and wanted to ask a quick question or 2.

I had the garage converted into a room and that's where the fuse box is.

When they install the EV charger,  what sort of work am I looking at connecting the charger?

I appreciate that it's not going to be an exact answer but I wanted a rough idea. The house was built about 25 years ago and had the standard fuse box. Will it mean another box next to the fuse box? I don't want a cable running along the inside wall so is it that the just drill through and run the cable outside? Any pics of the install inside and out?

Any recommendations on a charger as well? Looks like a bit of a minefield with issues people are having re charging levels etc

Thanks
