Having read the replies to my question a while back, I'd like to run the
following calculation before the group:

Appliance maximum power in kW:
Oven = 2.3
Hob = 6.3
Micro = 3
Total = 11600W

11600W / 230V = 50.43A.
...

You can't bring the hob into this equation Antony. The hob will need its
own supply as it is a heavy load appliance. The only types of loading you
should supply with a ring final circuit ate loads which can safely be fused
with up to a 13 Amps fuse.

230 V / 13 A = 2,990 W

The oven and hob make up a total loading of nearly 9kW on their own, which
can safely be supplied through a radial circuit of 10 mm csa' at 40 A safety
breaker.

It can be possible for all these appliances to be on at he same time, so
they should be rated in your design as such where ever possible. Diversity
is only a ruling on a single free standing stove, not separated cooking
appliances.
