Light fitting and switch problem

[Jurassicspark]

It could be, but as I said earlier, with only a red, blue and yellow wire into both ceiling switches, we seem to be missing something!

Nothing wrong with that.

My money is on the COM terminal missing a live feed from the other gang of the switch. A common mistake is people missing to put a link between COM 1 and COM 2.

As I said above, testing would confirm this.

Nothing wrong with that.

No nothing wrong with that, if the red, blue and yellow were coming from different cables.
It appears in both pictures that the red, blue and yellow are coming from the same cable; another connection/junction box would be required, hence the "missing something".

Does it?

Does it?

Well, shall we ask the OP?
@weehoose , is it possible to see if the red, yellow and blue wires come from the same cables, at both switches?

I'm going for a circuit arrangement like...

Yes agreed, this version often pops up too using a 4 terminal junction box with the earths joined together using a terminal block, either inside the juntion box or around the outside.

Unfortunately I can't get into the ceiling void at the moment. I would need to cut a hole in the plasterboard in the ceiling. Could it be as simple as a lose wire in the junction box? I think the previous owners were keen DIYers but nothing seems to have been done too great.

Really ?
You live in a dwelling with a "ceiling void" which cannot be accessed ?

How was the wiring installed, initially?

There should be a "Person Access" Hole (trapdoor) - somewhere.

The cable in the second switch goes down the way. I'm guessing to these in the cupboard where the fuse box is.

I still don't see a cable with red, yellow and blue wires in your last photo.
Would it be possible to confirm...

Yeah, lost count over the decades how many junction boxes I've seen where all the CPCs come back out to a terminal block, or even worse, they're just twisted together...

It's the downstairs so no access

Yes there is red, yellow and blue in the 2nd socket

as this is the hallway I guess the 'ceiling void' is covered with floorboards and carpet or laminate flooring. Pretty much like all standard properties.

My apologies.

I was considering a "Ceiling Void" to be a "Roof Space",
which (I think) is evident from my comment concerning a "Person Access" Hole (trapdoor).

However,
this was written (by the OP)

?!?!?

I was the first to mention "ceiling void" in post #12 - I meant it to be ambiguous, as I was not sure whether the hallway was on the ground floor, or first.
Mentioning a "ceiling void", would cover both scenarios, as in the space, hole, or cavity above the ceiling.
Cutting a hole in the plasterboard, would be an adequate way to reach a junction box within the ceiling void - I think there may be something lost in translation!

Thank you.

It is always "difficult" when "New" (or even "Experienced") posters POST that which they may think is "sufficient information".
However,
that is not always so!

It is then necessary to "interrogate" them (as politely as possible)
to determine the actual situation.
