Until the 1980s, the foundation behind Regensen, Kommunitetet, provided free housing and a scholarship for students chosen for admission.

Because of financial difficulties, a small fee was introduced, which helps to contribute toward the cost of utilities, which today is around DKK 1,600 per month.

Many of Denmark's major social and political debates through the ages have taken shape in the college, through the many prominent alumni ranging from scientists to dramatists, novelists, poets and politicians.

Regensen is also characterised by an intricate calendar of special feast days that are observed in the Great Hall with a complex array of festive traditions.
