The CU is pretty old (1995 when the house was built). There is a

You appear to already have a cooker circuit there with a 32A MCB on
it. Any reason why you are not using that?
If you use that then its a like for like swap of appliance, and you
don't need to meet new requirements for cable protection.
If you want a completely new circuit, then looking to see if there is
a RCBO that will fit that CU might be a more pragmatic answer.
(especially with the space afforded by removing the water heater MCB -
so even a double module RCBO would be ok).
(Another option for more RCD space would be to get a longer bus bar
for the RCD side, and shorted the non RCD side, so you move the split
to the right a bit - but the RCBO would be a better choice IMHO).
Sorry John but that's not going to work on the Memera 2000.
They are a fixed bus bar CU and that is not a spare way next to the main
switch but a deliberate unusable blank..
ok that makes it harder :-)
Although one could replace the existing cooker and water heater MCBs to
get two free adjacent ways.
That could allow a single double width RCBO to be sized to satisfy the
diverse load of both cookers.
A single module RCBO might work.
I don't recall having those CUs open (at least not the plastic version),
how much height is there available inside?
