Williams started his footballing career at his local club Cradley Town in 1990. After impressing in the lower leagues he attracted the attention of Football League sides and joined Welsh side Swansea City in 1991. After having a decent season with Swansea he move on up to Coventry City the following season. He spent three years with the sky blues making 80 league appearances, the most he would acquire in his career. Williams' early goal against Middlesbrough on 15 August 1992 was only the second goal ever scored in the newly formed FA Premiership. Whilst at Coventry Williams had loan spells at Notts County, Stoke City and at his old club Swansea City. He left Coventry in 1995 and joined new league side Wycombe Wanderers to start a somewhat nomadic career. After two years with the chairboys he moved on to unsuccessful spells at Hereford United and Walsall. Williams then went on to have a new club every season starting with Exeter City in the 1997–98 season. He went on to play for Cardiff City, York City, Darlington, two seasons with Swansea City his third spell at the club and his final Football League side Kidderminster Harriers. Known as the "flying postman" due to his speed and career before football, when playing for Kidderminster scored famously against Wolves in the FA Cup 3rd round only for his goal to be equalised in the final minutes. Following the end of his professional career Williams has gone on to have a similar nomadic career in non-league football. These clubs are Bath City, Redditch United, Evesham United, Weston-super-Mare, Stourbridge, Willenhall Town and most recently Boldmere St. Michaels. This has taken his total number of clubs to 22. He joined Willenhall Town managed by Mel Eves, in September 2007. In August 2008, Williams, now aged 40 scored a hat-trick for Boldmere St Michaels against Shifnal Town.
