5 Unforgettable London Conference Venues That Wow in 2025
Let’s be honest — not all conference venues are created equal.
Some are just rooms with projectors. But others? They’re statements. Spaces that inspire, impress, and elevate everything you’re trying to say. Spaces that make people lean in when they walk through the door.
At Lotus Events, we’re lucky to work in London — a city packed with incredible venues. And in 2025, these five are not just “good” — they’re unmissable. From riverside icons to raw, industrial playgrounds, here are the places we love bringing events to life in.
1. Exhibition London — White City’s Industrial Showstopper
Tucked behind Westfield in White City, Exhibition London is what happens when you take a historic engine house, restore every detail beautifully, and then fit it out with world-class sound, staging, and lighting.
The space feels electric. With its soaring ceilings, original brickwork, and built-in stage, it’s a dream for creative conferences, fashion-forward events, or product launches that want to go BIG.
- Up to 1,500 guests standing, or 780 seated
- 2 mins from the Central Line
- Effortlessly cool, totally professional
This is not a beige-carpet-and-bad-coffee venue. This is a “let’s make an impact” venue.
2. The Londoner — A Super Boutique Masterpiece
Picture this: you’re in the heart of Leicester Square, stepping into the world’s first super boutique hotel. It’s sleek, polished, and impossibly stylish. Welcome to The Londoner.
Everything here is luxurious — from the grand ballroom with soft lighting and velvet finishes, to the rooftop bar with skyline views. Hosting an executive summit? A creative leadership retreat? This is where you impress the people who aren’t easily impressed.
- Ballroom holds 850 for receptions, 700 theatre-style
- Top-tier rooms, dining, and service under one roof
- Perfect for: high-end conferences with sparkle
Bonus: when the conference ends, Leicester Square’s buzz is right on your doorstep.
3. The Pelligon — Canary Wharf’s Hidden Gem
If your event has ambition, The Pelligon is your canvas. This waterfront warehouse in Canary Wharf has become one of London’s most exciting venues — and for good reason.
It’s raw, modern, and versatile. There’s a massive glass dome (yes, really), exposed textures, and enough flexibility to shape the space exactly how you want it. Want theatre-style with dramatic lighting? Or standing cocktails with digital installations? This place eats creativity for breakfast.
- 750+ capacity, plus outdoor terrace
- For bold ideas and big thinkers
- Ideal for: innovation forums, tech launches, and edgy brand events
We love this venue for clients who say: “We don’t want the usual.”
4. InterContinental — The O2’s Crown Jewel
Let’s talk scale. InterContinental London — The O2 is not playing around. We’re talking Europe’s largest pillar-free ballroom, panoramic river views, Michelin-level dining, and seamless access to the O2 Arena next door.
It’s the kind of place where global brands host annual conventions. Where keynote speakers get standing ovations. Where every tech requirement is met without blinking.
- Over 3,000 guests in one room? No problem.
- Luxury hotel, spa, and restaurants all onsite
- Ideal for: major international conferences and award shows
Yes, it’s big. But it’s also beautifully executed. Scale and style? Yes, please.
5. The Beams — London’s Most Creative Blank Canvas
If you’re dreaming big, let’s talk about The Beams. Nestled in East London’s Royal Docks, this former industrial site is now a creative playground for large-scale, experiential events.
It’s not polished. It’s powerful. Think 55,000 square feet of exposed beams, concrete drama, and space to build anything. LED tunnels, immersive zones, theatre seating, dance floors — you name it, we’ve built it here.
- Space One alone fits 4,000 standing
- Fully customisable — from raw to radical
- Ideal for: immersive brand takeovers, fashion shows, or tech summits
We love The Beams because it gives our designers the freedom to really go wild.
