It is almost inexplicable that BT have one more major category of premise that they have declined to deliver high speed Infinity to.

If your premises are part of a large development, are part of medium scale multi-occupancy development or have premises that somehow prevent BT from linking to you on and individual basis, BT might declare that they are still trialling those types of installations.

This can be interpreted as meaning that BT will defer this type of installation until they are ready and not before.
