That should generally happen, as long as the feed cable has a higher current mcb/rcbo than 32A, i/t curves will generally result in discrimination.

I dont see why it would be.

In this case it is the feed for all of the kitchen, lights, cooker, sockets everthing.

Indeed, but thats a very different thing to the whole exercise being pointless

I thought there was lighting on another 2 core circuit. If thats retained along with the new circuits, lighting isnt lost from a trip. Losing all the lighting is what should be avoided.

No. You are not wrong.
Of course fuses/MCBs sometimes seem to disagree with me with regards to discrimination. Old fuses are often not up to the job.
