Meanwhile, Thes Sport started its rise in the ranks of Belgian football, promoting to the first provincial division in 2003 and even into the national leagues in 2005, before relegating back in 2009. In 2015, the club again gained access to the Belgian Fourth Division, the lowest level of national football, at which time the merger with VK Penarol Engsbergen did complete and the latter ceased to exist. Following a title in the 2017–18 Belgian Second Amateur Division, the club promoted for the first time ever to the third level of Belgian football. "As of 3 March 2019."
