I have a toothbrush charger that is supposed to have a standard UK bathroom plug, but when I'm trying to plug it into the socket, it is very loose, and I'm not sure if it is charging as there is no indicator on the charger. See the images below. Is it the plug that is non-standard or is it the socket?
Note this is not a standard European plug - I have a EU extension cord so I checked. The span of the pins is too narrow. It is a BS4573 plug.
