The man band set up company TT5 three months after being reunited as a five-piece in July, 2010 and have since accumulated more than £2.5million in the bank and are owed a further £5.1million, according to The Mirror.
The money is thought to be a result of their album, Progress, which was released last November, and their record-breaking sell-out tour which saw 1.34 million tickets sold in less than 24 hours.
A source said, “Touring has seen the band’s finances rocket. It was very, very lucrative and it’s little wonder they have so much in the bank between them.”
