The hall was bought by Nottingham Council in 1925, and opened as a museum in 1926. In 2005 it was closed for a two-year refurbishment and re-opened in April 2007. The prospect room at the top of the house, and the kitchens in the basement, were opened up for the public to visit, though this must be done on one of the escorted tours. The latter can be booked on the day, lasts about an hour, and a small charge is made.
