I suspect that that there is a growing acceptance that 13 amp plugs and sockets can not reliably carry 13 amps long term.

Most new domestic appliances are now limited to about 10 amps. The main exception being kettles, these are used so briefly that a full 13 amps is fine.

Electric immersion heaters often use a full 12.5/13 amps for many hours at a time, and it is now generally accepted that they should not be connected via 13 amp plugs.

Electric cars often have the facility to charge rather slowly from a standard 13 amp socket, it is recommended to limit the input current to 10 amps in such cases to avoid overheating.
