In March 2010, Harlequins announced that they had signed Smith from the start of the 2010/11 season. Smith said after returning to England from a stint with French club Montpellier: “I am really looking forward to coming back to England and joining such a prestigious club, and one which has so much history. It boasts an exciting and young group of English players, some of whom I have been lucky enough to have played with during my time in the Saxons and the Churchill Cup. Quins is a team which is going in the right direction and I want to be a part of it.
