As pointed out already, you can't put a wrong fuse in a 13A
plug. All appliance cords and appliancs are required to remain
safe when protected at 16A nowadays, so all* BS1362 fuse values
are OK.

*Minor exception, but strictly 1A BS1362 fuses should not be
used in BS1363 plugs because they are not ASTA approved and
would therefore result in a PAT test failure of the appliance.
