House Wiring, With Shower

[krazaq]

What consumer unit would anyone recommend and is the wiring correct below

Downstairs Ring Circuit B32
Downstairs Ring Circuit Kitchen B32
Upstairs Ring Circuit B32
Attic Ring Circuit B32

Downstairs Lighting B6
Upstairs Lighting B6
Attic Lighting B6

Cooker Cable 6mm Direct B32 (or not?)

Shower 1 Cable 10mm Direct B40
Shower 2 Cable 10mm Direct B40

1.5 mm Fire Alarm 2 Core Cable B6 (or not)

Can someone help me out on the MCB's, are they correct.

The consumer Unit will have two RCB's, and can the Cooker MCB be outside the RCB????

And any recommendations on how many MCB's on each RCB????


I hope this is not too much for you guys...

One more thought I have had, why not get rid of all MCB's and RCB's and replace all on a RCBO system, with each circuit having its own RCB... Would that be recommended?

Thank you guys..
