After appearances around the country, including at the JMA in Reading earlier this month, fans have been logging on to buy a copy of the band's debut single, All Time Low.
The Wanted, made up of Tom Parker, Siva Kaneswaran, Max George, Jay McGuiness and Nathan Sykes, spoke to Matt Wilkinson on Capital Radio last night.
They said: "We can't say thank you enough to everyone, thank you to everyone who's gone out and bought it."
All Time Low was this weeks highest new entry.
Yolanda Be Cool & D Cup scored the number one spot with We No Speak Americano.
