Bradley has played for England on over 25 occasions since her debut against Austria in August 2010, including appearances at the 2011 FIFA Women's World Cup.

Bradley remained with the club but suffered a severe knee injury in a July 2014 match against Yeovil Town, which caused her to miss the entire 2015 season, including the 2015 FA Women's Cup Final at Wembley Stadium, which County lost 1–0 to Chelsea.

[18] Bradley was named to the 2011 FIFA Women's World Cup squad, and appeared as a late substitute for White in the 1–1 draw with Mexico[19] and the 2–1 win over New Zealand.

[25] She was drafted into the starting line up when Ifeoma Dieke was injured, playing alongside Lincoln teammate Casey Stoney in Team GB's 1–0 win over Brazil.

[28] Although paid by Lincoln and possessing an England central contract worth £16,000 per year, Bradley maintained her part-time job in the care home owned by her family while playing in the WSL.
