Light wiring query

... with those colours and no sleeves.

Are you unsure about the purpose/usage of any of the conductors?

Totally, as this point in time we have absolutely no idea what one of the wires is used for.

Just in case your post is not flippant, they are the wrong colours for new build/new works and without brown or red sleeves this will fail any inspection.
Assuming of course these are all live wires and not neutrals/switched neutrals like I found in one house.

I hope it's not a new build with those colours and no sleeves.

If it were a new build, where would the builder or electrician have got R/Y/B 3C+E cable?

I have.

Why?

and without brown or red sleeves this will fail any inspection.

By a jobsworth? Are the conductors not "identified"?

There are two blue wires; do you think they are neutrals?

I'm guessing its not new build. Those lamps are ancient, and there's an old hole drilled in the mortar in the first picture.
Although the cleating is neat enough. Probably done by a jobbing handyperson.

It's also a disgusting way to supply the lights.

I think that's a tad OTT.

I have seem countless 1000's of installations like that and only seen a handful of cases where the PVC is affected by exposure to the elements.
In some of these cases (installed in the 60's), the sheath had become slightly pitted and the clips were friable.

In the couple of cases I had need to IR these cables, the results were very high.

It is possible that, as this is a newly moved-into house, the connections are faulty at the fitting/s (if a three core goes outside, there could be live feed and a switchwire along with the neutral).

 

[securespark]

There is another possibility I have just thought of.
Unlikely, but possible.

If the middle yellow was the live feed and the middle red with the link was the hall switch wire, when both middle and right hand switches are closed, the outside lights would come on with the hall light.

... but OP says middle switch has no effect on anything.

Exposure damage is irrelevant.

It could be the best cable ever, and last a million years in the harshest environments, but that would still be a disgusting way to install it. It should not be visible.

I hate you.

EFLI:

Ah...ah...ah, but...but......

If he operated it and the hall light was off, it wouldn't.

 

[EFLImpudence]

No, he says right hand switch turns on/off downstairs and outside lights - and centre switch makes no difference, which is why I suggested centre switch is stuck on regardless of rocker position.

Either that - or that is how downstairs and outside lights are supposed to be.

I still want to see the hall light wiring, with that switch configuration I would expect to find the blue wire from the non working switch at the ceiling light not connected to anything, and the live to the outside light connected in with the yellow feeding hall light.

 

[EFLImpudence]

The non-working switch is the centre one with the yellow, but yes (other way round)
