A very small amount of merchandising has been produced for "Star Cops". To coincide with the broadcast of the series in 1987, BBC Enterprises released Justin Hayward's theme song "It Won't Be Easy" as a 7-inch and 12-inch single. The 7-inch included the track "Outer Space" by Hayward and Tony Visconti, which was one of the incidental music tracks written for "An Instinct for Murder", on the B-side. The 12-inch had an extended version of "It Won't Be Easy" on the A-Side and the 7-inch version of "It Won't Be Easy" and "Outer Space" on the B-Side. "It Won't Be Easy" was later released on compact disc as part of the compilation "The Best of BBC TV's Themes".
