Futcher started his professional career with hometown club Chester in the Fourth Division, appearing in four first-team games under Ken Roberts in 1973–74. He moved with twin brother Paul on to Harry Haslam's Luton Town for a joint £125,000 fee in June 1974. He scored seven goals in 17 games in the First Division relegation campaign in 1974–75, including a hat-trick against Wolverhampton Wanderers. The "Hatters" remained in the Second Division in 1975–76. He bagged 13 goals in 1976–77 to become the club's joint-top scorer (with Jimmy Husband). He hit 10 goals in 1977–78, as did Phil Boersma, to again become the club's joint-highest scorer. He left Kenilworth Road after David Pleat was appointed manager. In August 1978, Futcher transferred back to the top-flight with Manchester City and played at Maine Road for the 1978–79 campaign, scoring seven goals in 17 league games for Tony Book. This included a hat-trick in a 4–1 win over Chelsea at Stamford Bridge on 17 September.
