Britton began his playing career with Celtic, making two league appearances and spending time on loan with Reading, where he played the same amount games before beginning the first of two spells at Partick Thistle in 1992. In two years at Firhill, Britton played in over sixty league matches, scoring fifteen times before moving to Dundee. Again, this was to be the first in two spells at a club for Britton, and he managed a similar record at Dens Park before signing for Dunfermline Athletic in 1996. Britton managed thirteen league goals in his first season at East End Park, helping The Pars to fifth place in the league. The following season, Britton only appeared in around half as many matches and scored just three times as the club finished eighth. In 1998–99, Britton began the season in the first team but after just one goal by mid-November, had a month on loan with Raith Rovers, where he scored once in five matches. He returned to the Dunfermline team in December but with only more goal all season, found himself released in the summer. Britton joined Second Division champions Livingston in June and played in around half the club's league fixtures, scoring five times. The following season, he played slightly fewer matches but scored a hat-trick in his final appearance as Livi won the First Division. Rather than move back into the Premier League, Britton stayed in the First Division by returning to Partick Thistle, who had just clinched the Second Division title. Britton hit twelve goals in the league as The Jags won a second successive title, ensuring he also won a second successive First Division title. Thistle finished in tenth place in 2002–03 with Britton netting five league goals. In December the following season, Britton was appointed co-manager with Derek Whyte but the pair could not prevent Thistle from relegation.
