Leake was born in Small Heath, Birmingham. After leaving school he trained as a blacksmith with Hoskins & Sewell, manufacturers of metal bedsteads, in the Bordesley district of Birmingham, and played for the works football team. He later helped Old Hill Wanderers win the championship of the Birmingham & District League in the 1893–94 season. His success with Old Hill did not go unnoticed, and he signed for Small Heath, newly promoted to the Football League First Division, in July 1894. Leake made his Small Heath debut in October 1895 at left half, but from midway through that season for the following four years he rarely missed a game at centre-half. He was soon appointed captain. When he did suffer an injury early in the 1899–1900 season, inside forwardWalter Wigmore was tried at centre-half, and by the time Leake regained fitness, his position was taken. He played the remainder of his Small Heath career at left-half or occasionally inside-left. He helped the club gain promotion back to the First Division in 1901, but left at the end of the 1901–02 season when they were relegated again. During this season he played in an England trial match and with clubmate Sid Wharton played for an England XI in an unofficial international against Germany. In a 1901 profile of the Small Heath club and players in the Daily Express, C.B. Fry wrote: He joined Aston Villa in July 1902, when he was 31, and stayed five years. In his first season the club were runners-up in the First Division, and in 1905 he played in their 1905 FA Cup Final team which beat Newcastle United 2–0. While with Aston Villa Leake won five official caps for England, making his international debut at the age of 32 on 12 March 1904 in a 3–1 win against Ireland in Belfast. Leake found himself unwittingly at the centre of one of the great scandals of English football. In the last League game of the 1904–05 season, Manchester City needed to beat Aston Villa to win the title. It was a spiteful game, and he had been involved in confrontations, both physical and verbal, with opponents. Afterwards Leake, who had captained the side, claimed that City's Billy Meredith had offered him a bribe of £10 for his team to throw the match. Meredith was found guilty by the Football Association, fined, and suspended from all football for 18 months. Because his club refused to help him financially, Meredith made public the illegal payments Manchester City were making to their players. An FA investigation resulted in life bans for directors, long suspensions for players, and the club being forced to sell its playing staff. An Aston Villa match programme of 1906 describes him as: Burnley manager Spen Whittaker took him to the club in December 1907, by which time he was 36 years old. He stayed with them a further two-and-a-half years, playing a significant part in building a teamfor the future. His arrival has been described thus: When Burnley were promoted to the First Division in 1913, Leake was long gone, but he played his part. At the celebration dinner, the club chairman commented that: In 1910 he returned to the Midlands and played for one season with Wednesbury Old Athletic, newly elected to the Birmingham & District League. He then took up posts as trainer with Crystal Palace, Merthyr Town, and Walsall, and also coached at school level. Leake died in his native Birmingham at the age of 66.
