Yes, 2.5 with 20 mcb is fine. I do most my house rewires in radial, one for the kitchen, one for down stairs and another for upstairs. We are using less power now in the energy saving world. Not all of the 11 sockets will be used at the same time continuously. You could have 50 sockets and end up using 2. Rcbo seem more practical as with a split load it will turn off more circuits.

And Strima has a good point.

20 amp is tight for a kitchen in my opinion depending on what’s in it say a couple of sockets above worktop for toaster, kettle then you’ve got washer, dishwasher, dryer (constantly on in my gaff) so 20 amp I think is too low.

I would be putting a 32amp supply to any kitchen. Too many larger appliances, ie toaster, kettle, DW etc etc

If you don't want to work with 4mm but want 32a why not wire a good old fashioned ring in 2.5mm? Seems like an obvious solution.

Testing is the only way to be certain.

I can't completely agree with that statement. There is a reason inspection comes first in the phrase inspection and testing - it's because it is inherently far more important than testing. Testing merely supplements the inspection. So just because test equipment does not show any issue with cables (much of which is probably concealed in containment or the building fabric or buried or whatever) does not mean that they are necessarily in a safe condition.
