Just out of interest, how much did the sparky charge to fit the the type B and socket. I've got a friend that's currently getting quotes for a charger, and unfortunately hit, what I like to call, the "wedding cake situation" with installers ..... you want a cake? £10. Ohhh it's for a wedding £50!. He's getting quoted £350+ install if he supplies all the hardware (the charger is going on the other side of the wall to the consumer unit) And he's even tried offering to install the the charger on the wall, so it's just connecting wires and testing
. I'm wondering if you ask for a 32A commando and a type B RCD, and don't mention a car, you won't hit the £200+ "it's a EV charger" surcharge
