good practice for lighting circuit: kitchen separate to rest downstairs lighting?

[jfb]

As the title suggest - would it be viewed as good practice to put the kitchen lights on a separate circuit to the rest of the downstairs lighting circuit?

It is a small 2 bed only 40m2 downstairs so not a huge amount going on. Kitchen lights only equate to couple LED strips under cupboards and some downlights. All open plan downstairs.

 

Is it just to allow some light to be turned off if something trips a circuit?

On a small property there is no real benefit to splitting lighting circuits up. If you have dark corridors etc. Then it would be prudent to leave some lights on if breaker trips

I would not bother.

 

If you are worried about a single fault tripping multiple circuits, the best design change you could make is an all RCBO consumer unit rather than a more common dual RCD split load board.

My electrician split our house left to right so if a trip went it left some light on the same floor, not heard of that before but made sense.

If you are going with a split load board, a good split is upstairs lights and downstairs sockets sharing same rcd and vice versa.  So something tripping the downstairs sockets does not trip the downstairs lights.

 

All RCBO is still much better.

I’ll have a look as it sounds good. 
As an aside, what size breaker/cable would be sensible future proofing for an electric car charging point?
