Crashpad,
More info please.....Doing a postcode and line check on all the majors indicates they don't provide in his area....Only BT and TT....If I could get him something unlimited for the same price TT are offering with phone and BB then result all round....
Quite simple really.
There are two ways ADSL to end up in your house. LLU Backhaul (using copper provided by BT Openreach) and BT Backhaul (by enabling ADSL signal on your common BT Retail PSTN - a.k.a "phone" - line).
Therefore, by definition, anyone who isn't a LLU operator will be using BT backhaul. LLU operators being : AOL, Be, Bulldog, Talk Talk, Sky/Easynet, Edge, Tiscali, Orange.
(Alright, perhaps a little bit of a over-simplification in the above paragraph because LLU operators can easily also operate BT backhaul in parallel in order to capture customers that they would otherwise miss ... and most do this. The other over simiplification is you've got to weed out the LLU resellers ... who are just middle-men).
Might be worth you trying the broadband checker at SamKnows....

If SamKnows shows any of the BT Wholesale products as being available to you, then the above statement about non-LLU operators applies.
