The Mazda motor manufacturer has its UK head office at the large Thames-side Crossways Business Park. Thomas Walter Jennings created the Vox musical brand, with products such as the AC15 and AC30 amplifiers originating in Dartford. In early 2006, the since-closed South East England Development Agency (SEEDA) purchased the former Unwins (an off-licence chain that went into administration in 2005) depot on the edge of the town. The warehouse was demolished and a business centre, The Base, built in its place. The Base will be managed by Basepoint Centres and funded by the non-departmental public body, HCA.
