Dalén took his design to Britain in 1929, where it was first manufactured under licence in the early 1930s. The cast iron components were first cast at the Coalbrookdale foundry in the 1940s, where they are still made today by the Aga Rangemaster Group. Its popularity in certain parts of English society (owners of medium to large country houses) led to the coining of the term "AGA Saga" in the 1990s, referring to a genre of fiction set amongst stereotypical upper-middle-class society.
