Sheffield's Biggest Monday Student Night Returns

It's finally time to reunite under the lights of Tank the wait is over. SuNKeN returns to launch a brand new season with the Freshers Opening Party part two, one of the most anticipated events of Sheffield Freshers Week 2026.
Now in its 13th year, SuNKeN has earned its reputation as Sheffield's biggest and most loved Monday student night, and this year promises to be our biggest yet. Expect sell-out crowds, next-level production, and an energy you'll only find in the underground setting of the iconic Tank.
Featuring top student DJ talent plus a surprise special guest headliner, the Opening Party is your first taste of the madness that takes over Tank every Monday throughout the semester and a must for any Sheffield fresher's 2026 calendar.
