sounds like you have 2 way swiching there, but you haven't found all the wires, are sure there isn't some more tucked up in the ceiling, or maybe a loop behinf the switches (unusual)?

The grey wire i found is coming from the com on the switch then into the rose but i cant seem to find any wires tucked behind the ceiling i find it it a bit odd myself.

your boib to need to remove the switch plates then buzz these wires out with a continuity tester to try and work out what feeds what.

I think I can see what is happening with the cables you have (This is probably the last light on the lighting radial circuit) which explains why you don't have too many cables but I am confused by the bedroom light coming on. One of the reds shold be your live feed to the switch, they should go into the same block. one of the blacks is your switch live (should be sleeved with red or brown tag, but often isn't!) and connects to the live on your lamp. the other black is your neutral, but that leaves your grey wire. you don't have enough left for there to be 3 core feeding 2 way switching. can you see the grey disapearing into some grey or white insulation with some other cables or is it running as a single?
This is tricky without seeing it and being able to Buzz it out, don't know if KB can help, I think he's a bit more experienced than me in the layout of strange lighting set ups!!!

The grey wire is a single one but when i took the single switch off the grey wire is going from the common terminal then up to the rose.
Is it possible it might go with the black switch cable and put the brown lamp wire with the reds because ive tried putting the grey wire with the reds and getting no light but when its with neutral im getting some light.
But what happens is when i put the bedroom light on im getting full light in the landing and i bit dimmed in the bedroom the same with the toilet and in the back bedroom there is a little bit light.

mate, you've got issues!!
time to get a spark in I'm afraid. also that grey doesn't meet the regs if it's a single with only single insulation along it's length. sounds like you've got a major bodge on your hands there.

yes the cables are singles- 2 reds 2 blacks with one being the switch cable i think, and this single grey wire which is a touch thicker than the rest.
im totaly lost on this one.
