Domestic lighting circuit identification problem

[gaz05]

Hi, I'm in the process of sorting out a few things before changing the consumer unit at my moms' house (I only finished college last June so still wet behind the ears and have loads to learn). The bedroom above the garage was built as an extension years ago and the feed for the bedroom light was taken from the landing light, which in turn is on the downstairs lighting circuit. So incorrectly identified at the consumer unit for isolation.
Having checked all the other lighting points upstairs they are wired in singles and at the ceiling rose only switched live, presumably why the extension was taken from the landing... What options do I have? Is labelling with a note on the downstairs breaker good enough? If not would mean re wiring the upstairs lights no?

Thanks for reading and any input

from what you describe, i wouldnt be surprised if the upstairs and downstairs lighting circuit dont share a neutral that feeds the landing light. so you may find that if you put upstairs and downstairs on a different rcd, one of them will trip when you turn the light on. It happened to me last week, and it seems like the same layout as yours, landing light on the downstairs lightingcircuit.
