In 2002, the company acquired the Estonian Monex network from Hansa Bank.

Reviews.
A report by the "Sunday Times" found that ChangeGroup offered the best online exchange rates on euros when it conducted research in July 2011.
In 2002, the company's high street offering was criticised by two newspapers comparing currency exchange rates, the "Sunday Mirror" (who described them as "worst on the High Street") and the "Los Angeles Times" ("the worst deal of my London experiment").
