BBC Radio 4 Extra is broadcast from Broadcasting House in central London, although due to the nature of the channel very little of the channel's content is broadcast live from there with even the continuity announcements being pre-recorded. The channel uses ten continuity announcers to link between programmes. Notable announcers include Wes Butters, Kathy Clugston, Jim Lee, David Miles, Susan Rae, Alan Smith and Zeb Soanes. Previous presenters, including those presenting Radio 7, include Penny Haslam, Helen Aitken, Rory Morrison, Steve Urquhart, Alex Riley and Michaela Saunders.
