Simmons | Holborn

Two floors of neon-lit party infrastructure, a 3am late licence Monday to Saturday, and a location seconds from Holborn station — Simmons Holborn is built for celebrations that run long and loud. The largest venue in the Simmons chain, it holds up to 450 standing across two fully self-contained floors, each with its own bar, DJ booth, toilets, and separate entrance. That independence matters: book one floor for an intimate 200-person party, or take both for a full venue hire that still gives you distinct zones within the same building.

Ground Floor at Simmons Holborn

The ground floor is the bigger of the two rooms, holding 250–300 standing or 80 seated. Neon signage, retro wallpaper, and a resident DJ spinning disco, funk, and 80s hip-hop set the tone without needing a decorator. A projector screen and photobooth are built in. The space has its own private entrance and cocktail bartenders behind the bar — your event stays self-contained from arrival to last orders. For corporate presentations that transition into a party, the projector handles the formal portion before the DJ takes over.

Lower Ground Floor

Below street level, the lower floor holds 200 standing with its own entrance directly from the pavement — a completely separate access point from the ground floor. The mirrorball-skull DJ booth is the centrepiece: a glittering oversized disco ball that the DJ actually plays from inside. Same infrastructure as upstairs — private bar, private toilets, standalone sound system, and a projector screen. For simultaneous events or a two-phase party that moves guests between floors, the layout works without crossover.

Why Simmons Holborn Works for Late-Night Events

The 3am licence is the standout. Most central London bars close at midnight or 1am — Simmons keeps going six nights a week. A five-hour happy hour running 4pm to 9pm daily softens the budget on drinks-heavy events, and the cocktail teapots served in vintage china add a quirky, photographable touch that works as an ice-breaker at team socials. External catering is permitted, BYO DJs welcome alongside the house setup, and air conditioning keeps both floors comfortable at full capacity. Holborn station is a 30-second walk, with Covent Garden and Chancery Lane equally close.
