Charging Range Rover to household socket?

By chance I read today that the charging cable for the household socket must not be connected to a multiple connector or an extension, because this can lead to damage or fire. Good to know. But: I have found out on the Internet that household sockets should not be used at all for charging. Although this charging is more gentle, there is fire risk! It is questionable whether this is covered by the insurance. I am very much concerned about this. wondered and wanted to ask you what you know about it or if it is current. Thank you!
