Hi again,
If what you describe is true, then here is probably how it should be wired (no promises
)
The two blacks from the bedroom rose and the bathroom rose should be terminated into the neutral (N) connector on your landing rose.
The single black conductor (from the landing light switch), should be terminated into the Line (L) connector on your landing rose.
The two reds from the bedroom rose and the bathroom switch should be terminated in the 'Loop' connector on your landing rose.
And finally, the red from the bathroom rose and the black from the bathroom switch need to be connected together - this is why I asked if there were any connector blocks
This will only work if
1/ your description is correct and
2/ the red conductor from the bedroom rose is a permanent live.
Have you any way of confirming
2/ above?
i have tested the black from the landing switch with my tester screwdriver it seems to be live all the time.when you say join the red from the bathroom rose and the black from the batroom switch which terminal do i put both these wires in
Hope that helps.
