463.1.3 Functional Switching (Control).

Could it be argued that 463.1.3 requires a separate switch for items like an oven, hob, refrigerator or washing machine etc. where the appliance has no means of external isolation/control except those on itself? Or are functional controls on the appliances adequate and sufficient?

surely you mean 'within reach' or 'rapidly and safely accessible', rather than a distance spec like less than 1m and not less than 150mm or something - being too specific will find all the impractical corner cases and invites ridicule. - after all 30cm away but on the other side of the wall is not so useful as 1m away but within reach of where you would actually stand.

But , if the CU is in the same room, why not the MCB ?

I really see no need to add a new requirement at all.
