Morning Grant - and

to Cable Fourm.
I can't directly answer your question (although there are a few NTL techs on this board who should be able to), but I do know from domestic experience that they are funny enough about cable that they have not installed themselves that they will probably have kittens at the thought of Freeview, digital satellite and cable signals all coming down the same length of user-installed coax.
While I admire your dedication to customer choice ... virtually every other landlord sets rules about what residents can or cannot hook up to, so I can't see the problem with you doing the same. Personally I think having your flats cabled for NTL is the easiest option.
