Using a 13A socket is not recommended by the government and car manufacturers and is a very slow way to charge your vehicle. Drawing this amount of current on a continual basis can put too much strain on some wiring systems and can be dangerous and create a fire hazard. The use of an extension leads from a 13A plug is definitely not recommended as this can overheat under the continual load.
