Initially, the NLAC was affiliated to the Motor Union (MU), a subsidiary of the Automobile Club of Great Britain (as the RAC was known at that time). However, at the end of 1907, the MU broke away from the RAC due to internal frictions. The RAC then announced a scheme whereby local clubs could become associates of the RAC, with representation on its committee. In January 1908, the NLAC changed its name to the North Middlesex AC (NMAC) and, on 1 January 1909, joined the RAC Associates scheme.
