Look....knock the supply off to the circuit feeding lamp/s in question and then using a voltage indicator test strappers IN BOTH DIRECTIONS. If theres still a voltage there then you know...........

Nah, mate. i use my trusty neon driver. LOL. seriously, though, there's not always 2 circuits there.the landing light could be on the downstairs circuit. it's a case of if we know what we're doing we check and check again.

So is anyone here...(Tony)? seriously suggesting that it's ok to knock off an mcb labelled downstairs lights and just assume all the downstairs lights/switches will be dead??.....Thats why we have safe isolation proceedures and voltage testers....anyone just assuming deserves a belt.

You NOTIFY IT at the board or on a pir form or an installation cert as this should be the first port of call to anyone (including competent persons) before undertaking any work to be carried out...........

i suupose it's each to his own. if , for example, i fit a FCU with a 3A or 5A fuse (say for security lights) i always label the FCU "3A FUSE" (or 5A).

you note it on a PIR, you code it. What as? you do not need to notify it at all. so you are telling me that on every PIR you do or installation cert you note that there is a 2 gang switch with 2 feeds! i've been through assesments with NIC and ECA, and this has never been mentioned. It is just one of them things that does not need to be done. And you cant say they wern't thorough because they even noted down that i should not be brown sleeving the switchwire on smoke detectors and that was about 10 years ago and i still see people doing it now.

telectrix that is fair enough because you are giving somebody/homeowner information they need to know because changing a fuse is within there capabilitys, but anybody who is removing the switch should have sufficient knowledge.

unless competent in the task you are undertaking do not proceed it is simple, so are you telling me you see a problem with a 2 gang switch? so you note every 2 gang switch on a PIR, move into a large scale property and your PIR will turn into war and peace. it does not need noting or labeling end of, lets not wrap our job into anymore red tape than it already is.

so you dont have a duty (moral or otherwise) to forwarn anyone else coming after you (competent persons) of this scenario?..........

it is within the capability of most home owners to replace a light switch. the sensible ones will isolate the CU before attempting this. then get confused with the switch wiring if there's more than 2 wires, so we come in and it's a case of "£40 to fix it, £60 if you watch, £80 if you've had a go yourself"

not sure how everyone else feels on this subject but i think it is exhausted now, so in a nutshell, some leave borrowed netrals on one mcb, some replace the strapers and remove the borrowed neutral, some label switches, some label back boxes some dont label at all, some think homeowners can change switches and some think they cant, some note it on the PIR some note it on an install cert and some dont note it all, some think the homeowner has the final decision and some believe they dont, so now that is all sorted i'm off to :banghead:

I would just like to say that its up to the competent person (sparky and/or homeowner) as to the action to take....BS7671 and anything seconded to it are after all only guidance notes.....

so..................... who's going to start a thread about an outbuilding with TNC-S exported from a CU with RCD front end protecting the whole installation, where the outbuilding neutral is taken from the upstairs lighting and the line directly from the RCD via a BS88?
