Due to a restructuring of elite-level women's football in England in 2014, the WPL had doubled in size from three divisions to six. With this in mind the league opted to introduce a new cup competition to run alongside their existing League Cup competition, the Premier League Cup, to cater for the increased number of teams. Seventy teams were entered into the Determining Round of the FA WPL Cup, with the 35 match losers being eligible for the Plate, but two teams withdrew from the competition, meaning only 33 teams took part.

Huddersfield town reached the final of a major cup competition for the first time in their history thanks to a 4–1 victory over Isle of Wight side Shanklin, witnessed by a small crowd of just 40 people at the West Yorkshire club's Storthes Hall ground. It was their second cup semi-final win in quick succession, having recently also reached the final of the Sheffield & Hallamshire Women's Challenge Cup. Emily Heckler scored twice for Huddersfield, and Kate Mallin and Debbie Hastings each scored once. Rowan Treagus scored Shanklin's consolation goal. Midfielder Alarna Fuller was named Huddersfield's Player of the Match. Preston North End earned their place as Huddersfield's opposition in the final through a 1–0 victory over West Ham United. The only goal of the game was scored by Preston's Chelsea Flanagan. West Ham, who were missing a number of regular first team players, rarely threatened the Preston goal, and eventually conceded the winning goal ten minutes from time.
