Louey was born in
Melbourne on 7 July 1909 to the son of a
Chinese Australian. He returned to China when he was young and was educated at the Holy Trinity College in
Guangzhou when his father and his uncle founded the
Kowloon Motor Bus Company (KMB) in Hong Kong in 1922. After he graduated, Louey joined the KMB as an assistant manager and rose to Chief Manager in 1933. At that time, there were several independent bus operators. William Louey bought a few of them and applied for the franchise of the bus service in 1933. He won the franchise to operate bus services in
Kowloon and the
New Territories, while
China Motor Bus (CMB) secured the rights to provide services on Hong Kong Island. Together with
Tang Shiu Kin, Lui Leung, Tam Woon-tong and Lam Ming-fan, William Louey renamed the company 'Kowloon Motor Bus Company (1933) Limited' (KMB). KMB services stopped operating during the
Pacific War and
Japanese occupation. After the war, Louey largely expanded his company from about 100 vehicles to more than 700. Before his death, he ordered more than 100 buses from the United Kingdom, bringing the fleet size to 895. Louey also experienced a few new company's change of policies. In early December 1962 when the workers took industrial action, Louey announced to raise the wage of the bus drivers. ==Public service==
