Hooper has not represented England at any level. His paternal grandfather William Hooper was raised in the Scottish Borders, and this led to hopes that Hooper could be eligible to play for Scotland. Then Scotland head coach Craig Levein sought clarification as to the place of birth his grandfather's birth certificate recorded, as he had been born in a hospital in the English border town Berwick-upon-Tweed. The possibility was closed off when it was confirmed that his grandfather was included in the English Births Index. On 13 March 2011, Hooper was included by Stuart Pearce in his 31-man squad for the England under-21 team to play Denmark and Iceland. However, Hooper pulled out of the squad due to injury. On 3 May 2011, he was named in the 40-man provisional squad for the 2011 UEFA European Under-21 Championship, but did not make the final selection.
