During the First World War UK activities were switched to aircraft production, and the UK business was bought by The Aircraft Manufacturing Company which was based at Hendon near London. In 1917, Vanden Plas (1917) Ltd. was incorporated. After the war it seems to have been a struggle to get back into coachbuilding and in 1922 that company was placed in receivership. The exclusive UK naming rights seem to have been lost, because in the early 1920s the Belgian firm was exhibiting at the London Motor Show alongside the British business. In 1923 the rights to the name and the goodwill were purchased by the Fox brothers, who incorporated Vanden Plas (England) 1923 Limited. They moved the business from Hendon to Kingsbury and built on the contacts that had been made with Bentley. Between 1924 and 1931, when Bentley failed, Vanden Plas built the bodies for more than 700 of their chassis.
