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

not an expert, just put a circuit chart beside cu and make a note aswell id say, telectrix hel tell ye,

I would make it as clear as possible that this is on the d/s lighting. Circuit chart,diagram,label. And keep it adjacent to the CU.

see, wasnt far wrong, i know me **** , but yes doubt meself too

Any decent spark who may work on your mums house in the future shouldn't just turn the upstairs lighting circuit off and assume that light is on the upstairs lighting circuit. Part of the safe isolation is to test to see if its dead before begining work, so if he does get a belt.....its his own fault

but yeh, would think a clear sign next to cu would be acceaptable!

Doing some work recently, isolated both CU (rewirable).
Bedroom ligt still worked.....
Main fuse fell out....
Bedroom light still worked.....


Looked into it a bit further and it is wired into next doors lighting circuit!!!


Now if ever there was an example for always testing for dead!!!

Shame it wasnt my house as would find a way to run my pool heater on 1mm rubber cables

You will be notifying the LABC and issuing the correct certs will you not?

why stop at just your pool heater?

well joe sometimes the lighting at top of stairs is live from downstairs circuit and neutral from upstairs circuit, so would still prove dead but when you disconnect it becomes live,

borrowed neutral monster?

lol @the pool heater. shove the storage heaters in as well, a bit of extra flex. in response to the op, you will have to put both lighting circuits on the same RCD, as you are, as you say, wet behind the ears, and the job is part pee notifiable, might be an idea to get a local part pee reg. eg elecsa or napit member ( there's anothe scam provider, but i forgot its name) to --- ist and test with you on this job. and I=P/U, i,m not from pakistan

[telectrix]
