The only problem i had with IBB is that they accepted my application, but never told me that they had no space on the aerials in my area. So i was left waiting for them to contact me to organise my connection, and only when i rang them to find out the delay did they bother telling me that they had no intention of setting me up as they lacked the capacity.

This is i suppose good news for you, as it is clear that they don't go beyond a certain point on an aerial, so the network is less likely to become overcrowded.
