About Venue

Unique. Out-of-the-box. Extra-ordinary. Welcome to The Mermaid London – the independent home of one-of-a-kind events, and the go-to venue for large-scale events in the City of London.

Five incredible event spaces and a capacity for nearly 2,000 delegates requires an expert team ... One that is dedicated? Yes. Experienced? Of course. Creative? Undoubtedly. Meticulous? It goes without saying. Passionate? Absolutely. All essential, and all characteristics that define The Mermaid London.

Versatile, stylish and contemporary, the Upper River Room is ideal for both corporate and social events including conferences, evening receptions, weddings, gala dinners and award ceremonies. With panoramic views of some of London’s most iconic landmarks, from the Tate Modern and The Shard to Shakespeare’s Globe and Millenium Bridge, our Upper River Room is guaranteed to put your next event on the map.

UNLOCK THE ULTIMATE EVENT EXPERIENCE
Adjacent to the Upper River Room is the Queenhithe. A flexible, extended space accessible via a movable wall, it is the perfect London party venue. Host a dinner in the Upper River Room and party the night away in the Queenhithe – like its namesake, make your event one for the ages.
If you’re looking for a corporate London events venue, the space also caters for smaller conferences and product launches. Directly below you’ll find the intimate Lower River Room where you could host a drinks reception or networking hour after an award ceremony or AGM.
For the ultimate event experience, why not combine these spaces to create one iconic venue that gives guests the wow factor?

Had our company's christmas event here. Spacious auditorium and backstage area where food & drink were served. Facilities were satisfactory and it is pretty easy to get to.

Quite easy to find. Accessible. 3 lifts. Decent toilets. Enjoyed my 2 day conference and training. From Blackfriars stn turn right then immediately right again. 60/80 Meters there's a small underpass

I have been here on a number of occasions for conferences. It's well equipped, things seem to run smoothly and provide everything that you would expect. The lunches are good and this time had gluten free options for mains, but not desert. The cookies at breaks looked delicious though no no gluten free choice, so I had to settle for healthy, fruit option. They really looked after my waistline! The staff are friendly and helpful.

The staff seemed to be intent on preventing delegates from doing things: e.g. "you can only have one type of food on your plate". Thankfully on the second day of the event this was no longer the policy. No coffee available at noon and nowhere to procure it on site (absolute showstopper for some of us).
