Any gotchas or is this a genuine question?

Apologies; genuine question! :-)

Doing a fair bit of DIY (including wiring) and have decided to replace
the current whole-house RCD'd CU and so with everything out thought I'd
ask for suggestions.


My suggestion is to put the kitchen sockets on their own RCBO and
consider doubling up the smokes with a lighting circuit of your choice.

My general suggestions are that fridge, freezer, central heating
(frost protection), and life support systems (such as tropical fish)
should not share an RCD with anything (or even each other).
Outdoor circuits should not share an RCD with indoor circuits.

Personally, I only ever install RCBOs, never an RCD covering multiple
circuits. They're cheap enough now (and I did this even when they
were expensive).

40 years ago, when I put the CU in this house, I'm not sure RCBOs even
existed
