The BT Tower was given Grade II listed building status in 2003. Several of the defunct antennae attached to the building could not be removed unless the appropriate listed building consent was granted, as they were protected by this listing. In 2011, permission for the removal of the defunct antennas was approved on safety grounds as they were in a bad state of repair and the fixings were no longer secure. In December 2011, the last of the antennas was removed leaving the core of the tower visible.
