For economy's sake, ASLEF initially chose to be managed by its Leeds branch, as a result of which its first head office was at the Commercial Inn, Sweet Street, Holbeck. It moved to 17 Mill Hill Chambers, Leeds, in 1885, and again to 8 Park Square, Leeds, in 1904. In 1921, it moved to London by buying a house at 9 Arkwright Road, Hampstead, from the family of the late Sir Joseph Beecham, Bt. For a period in the second half of the 20th century ASLEF also owned the next-door house at 7 Arkwright Road.
