There are so many different options, it's confusing. But a "proper" 7 kW charger can cost over £2000 to install if your house isn't wired in a convenient way, while installing an ordinary socket outside might cost about a tenth of that and give you 2.3 kW. You might get about 4.5 miles per kWh, so potentially more than 80 miles from an 8-hour overnight charge from an ordinary 230 V socket, which can deliver 10 A for a long time if it's a modern one and properly installed though you need to be a bit careful because it's not normal to take that much current from an ordinary socket and you'd be doing this at night so you should worry a bit about something overheating and catching fire. Worth getting someone competent to take a look at the wiring, I'd say.
Basically, as far as I can tell, you can take 10 amps off lots of places in an ordinary modern house, but to get 32 amps for a "proper" EV charger you probably need to go back to where the power supply enters the house and start there afresh with new and rather more expensive equipment and cables.
(US readers note that I'm talking about GB where domestic wiring is all 230 V.)
