That is what I said in my first post. But as you can see there is no standard way to wire so without being on site and being able to test we can only guess.
power off and Remove both and check switching operations with a multimeter
One grey is a switchline the other grey is the feed i would assume.
As in drawing one.
The light is Possibly via an unlocated joint somewhere, the light wires and the greys appear ok as the light goes on and off .
It is the two way switching bit , that is giving you problems.
right il have a look when i get in from work today, don't get as long to look as it seems to get dark up here quiet early now especially with the weather...
Thanks for all the comments and help, il let you know the results or if i need any more help (im sure i will)
go buy a new cheap switch..
change it for one of the existing switches and see if it works properly.. if it does then the switch was knackered..
if it doesn't, put the original switch back and swap the other one for the new one..
if it doesn't work with either switch swapped, buy another new one and try swapping BOTH of them..
AHHHHH looks like it was the switch that was originally left intact upstairs...it was a very old thing took it out swapped with new and its working fine now, so i can turn it off or on upstairs or down...now to sort the missing landing light :s
