You walk into a massive hall. It’s buzzing. People everywhere. Suits, lanyards, coffee queues. Someone’s pitching a product on one side. On the other, a crowd is huddled around a demo screen. You’re meant to meet people in large conference venues in London — but where do you even start?
That’s what big conferences in London can feel like. Brilliant, yes. But a bit overwhelming, too.
The biggest and most exciting conference venues in London
London has some of the best venues in Europe. From smart corporate spaces to huge arenas where deals happen between coffee sips. But while the buildings are big, the real magic comes down to small things — like a quick intro, a shared link, or a QR code that makes someone remember you.
That’s where Profyle Digital Business Cards can be helpful. No printed cards to lose. No awkward typing of emails mid-handshake. Just one tap, one scan — done.
In this guide, you’ll find 13 of the best large conference venues in London — along with ways to actually make real connections once you’re there. We’ve also included tips on how to use your Profyle Card to make each event worth your time (and train fare).
Let’s start with the biggest of them all.
What is the largest conference centre in London?
Over 4 million people walk through its doors each year. That’s more than the entire population of Birmingham, Liverpool and Bristol — combined. And they all come to one place: ExCeL London.
If you’ve ever walked into a venue and instantly felt lost, you’ll get it. Large venues can feel like small cities. But ExCeL is built to handle that. It’s London’s biggest conference centre and one of the busiest in Europe.
Quick facts:
- Located in Royal Docks, East London
- 100,000m² of event space
- Hosts over 400 events each year
- Used by global brands, major expos, medical summits, tech conferences, government events
You’ll find everything from Comic Con to fintech launches happening here — often on the same day.
Why ExCeL Stands Out
- Scale: Two massive exhibition halls, plus 45 meeting rooms
- Transport: Right next to the DLR and the Elizabeth Line (custom-built for ExCeL)
- Hotels: 3,700+ hotel rooms within walking distance
- Support: On-site AV, catering, and even security
But here’s what sets it apart — ExCeL London is where deals worth millions get started. Exhibitors and attendees come from 130+ countries. It’s a global hub in a docklands shell.

What is the biggest council house in London?
Some buildings were made for meetings. Others were built for decisions. That’s Kensington Town Hall — the biggest civic space of its kind in London.
This isn’t the kind of “council house” with a flat and a postbox. It’s the seat of local government in one of London’s best-known boroughs. But it’s also a very popular venue for community events, business meetings, trade shows and even weddings.

What is a famous place for public meetings in London?
Some rooms have more stories than a newspaper stand. One of them is Friends House, right across from Euston Station.
It’s known for big public meetings. Political debates. Talks about climate. Education forums. Peace rallies. If people have something to say, chances are they’ve said it here.
It’s run by Quakers — simple space, big impact. And it’s been that way for over 100 years.

What is the biggest concert arena in London?
You don’t forget the sound of 20,000 people singing the same chorus. It shakes the seats. It hits your chest. And it happens every week at The O2 Arena in London.
This place is huge — one of the busiest indoor arenas on the planet. In fact, it’s been named the busiest music arena in the world more than once based on ticket sales. Big artists book it months — sometimes years — ahead.
But it’s not all concerts and screaming fans.
Quick facts
- Where? Greenwich Peninsula, South East London
- How many seats? 20,000
- Who’s played here? Beyoncé, Coldplay, Adele, Elton John, and many more

What is the most famous concert hall in London?
Some stages don’t just host music — they hold history. That’s what the Royal Albert Hall is. A big red circle with a roof that’s seen everything from Beethoven to boxing.
It’s been around since 1871, opened by Queen Victoria, and hasn’t stopped since. Walk past it today and odds are someone’s rehearsing inside.
Quick facts
- Where: South Kensington
- Opened: 1871
- Seats: 5,272
- Famous for: The Proms, Cirque du Soleil, rock concerts, awards, opera, comedy, and charity galas
- Bonus: The Beatles played here. So did Adele.
It’s not just posh either. The hall has hosted wrestling, science talks, and film screenings with full orchestras. Some nights you’ll see school choirs. Other nights? Eric Clapton.
It’s got gold rails, red velvet seats, and round acoustics that make a single violin sound like a full orchestra.
A famous hall, yes — but also a strong space for real work
The Royal Albert Hall also runs:
- Private hire for awards and ceremonies
- Business events and corporate evenings
- Green Room networking and reception spaces
The place feels grand, but the service is smooth. If you want your guests to remember the room as much as the speech, this is where you go.

What is the name of the biggest park in the centre of London?
Need to host a big event that doesn’t feel boxed in? Try a bit of grass. London’s biggest central park is Hyde Park — and it’s not just for tourists, joggers and people feeding squirrels.
It’s also one of the most popular open-air venues in the country.

- Where: Right in the heart of London — between Mayfair, Knightsbridge and Paddington
- Size: 350 acres
- Famous for: Public speeches, huge concerts, community events, charity races, brand activations
- Managed by: The Royal Parks
Hyde Park can host crowds of over 60,000 for large-scale events — including music festivals, marches, memorials, and corporate outdoor activations.
It’s where Queen played in 1976. Where BTS brought London to a standstill. And where locals do yoga next to multi-brand tech showcases.
Want to use the space? You can
Events in Hyde Park aren’t just for global megastars. You can apply to run:
- Wellness festivals
- Green trade fairs
- Fundraising runs
- Cultural or awareness events
- Branded experiences (pop-ups, trials, demos)
You’ll need to go through The Royal Parks and meet their sustainability and safety rules — but it’s very doable, and the location can’t be beaten.
