How exactly do you do that? Is a 3 pin plug suppled with the car? How long does it take? I didn’t know this was possible!
PHEVs are supplied with a charging cable that has a normal 3-pin plug on the end, so you just plug it in to a normal socket and connect the other end to the cars charge point. Motability won’t pay for a home charger (they only do for full electric cars) but you don’t really need one with a PHEV. It would be pointless going to the expense of fitting one yourself as PHEVs mostly charge at a much slower rate than EVs and the limited electric range you get doesn’t warrant one.
Do keep in mind though that for a PHEV to be right for you it is essential that you can charge at home, as public charging isn’t viable (cost or time wise). Also, they are only really worth having if 90% of your journeys are within the (limited) electric only range. As PHEvs are very heavy, they aren’t economical when the battery is depleted.
