Briggs made his debut for the under-19s on 13 October 2008 in a 4–1 European Under-19 Championship qualification defeat by Serbia at The Showgrounds in Newry, Northern Ireland. Briggs was a key member of England's squad that reached the tournament final in Donetsk, Ukraine in 2009. He was a late addition to the squad, having to fly back from Fulham's pre-season tour of Australia to link up with his teammates in Ukraine.
