The Dragon's Den set located at MediaCityUK is in Salford.
MediaCityUK is a large media and broadcasting development at Salford Quays in Greater Manchester. It became an important base for BBC operations and other media organisations, and Dragon's Den has been associated with the site for its later production.
Salford and Manchester are closely linked geographically, which causes the most common confusion. MediaCityUK is in the City of Salford, although it is only a short distance from central Manchester and is commonly described in relation to Greater Manchester.
The move reflects the wider relocation of substantial BBC production from London to Salford. The studio setting is a controlled television environment rather than a real investor's office, but the negotiations shown in the programme are framed as genuine business discussions.
