LOL, what a paper chase!
Ha indeed, really appreciate your help as well as the others who contributed.
So reading around on the link you shared it seems like the orange bell wire is surplus and can be disconnected...this also has a chance of improving ADSL speeds right?
So my options are I re-wire this myself but from what has been said this is really a "no no" and I should get BT out to do the job properly :-\
