So two 3kW kettles in a double socket is not acceptable?

It's not desirable, but in a domestic environment (and I've lived in
shared houses with two kettles, to cater for the home-from-work tea
stampede) they're only going to be used occasionally.

In a commercial kitchen (which could include a house doing B&B) more
appropriate provision should be made. Ring circuits should only be
installed where they are *suitable for the load*.

Yup. Commercial installations where continuous loads can be accurately
calculated are likely to use radial circuits - even if fitted with 13 amp
outlets.

If you intended heating every room in a house with a fan heater etc on all
the time to give 'central' heating, a ring wouldn't be appropriate.

Load diversity is the key, and it's applied to things normally fed via a
radial in the home like cookers and hobs too.
