Best Team Building Activities for Large Groups in London

Organising a team building event for a large group can be tricky. Activities that work well for small teams often struggle when the group size grows beyond 30 or 40 people.

For companies planning events for 50, 80 or even 120 employees, the best activities are those that allow everyone to participate without splitting the group into multiple sessions.

Here are some of the best team building activities for large groups in London, and what makes each one work well.

1. Corporate Game Show Experiences

A corporate game show experience is a live hosted team event inspired by television game shows.

Teams compete across interactive rounds using buzzers, scoreboards and puzzles, with a host guiding the event from start to finish.

Because the whole room plays together, game shows work particularly well for large groups of 20 to 120 people.

Typical rounds might include:

• survey-style questions
• word puzzles
• card prediction games
• price guessing challenges
• strategy and bluffing rounds

The format is fast paced and energetic, making it a popular choice for company socials, conferences and team celebrations.

2. Scavenger Hunts

Scavenger hunts are another popular option for large teams.

Participants are split into smaller groups and sent around a city solving clues, completing challenges and competing to earn points.

London works particularly well for scavenger hunts because teams can explore well-known locations such as:

• Covent Garden
• Soho
• South Bank
• Shoreditch

Scavenger hunts combine teamwork, problem solving and movement, making them ideal for outdoor team building events.

3. Cooking Classes

Cooking classes can be a great option for teams that prefer a more relaxed and social activity.

Participants work together to prepare dishes under the guidance of a professional chef.

Popular options include:

• pasta making classes
• sushi workshops
• cocktail and food pairing events

Cooking events are particularly popular for client entertainment and team socials.

However, large groups often need to be split across multiple cooking stations.

4. Quiz Nights

Quiz nights are a classic team activity and easy to organise for large groups.

Teams compete by answering questions across different categories, often with themed rounds and bonus challenges.

Quiz events work well in:

• pubs
• private venues
• conference spaces

While quizzes are familiar and easy to run, some teams prefer activities with more interaction and movement.

5. Outdoor Adventure Activities

For teams looking for something more physical, outdoor activities can be a great option.

Examples include:

• obstacle courses
• survival challenges
• outdoor problem-solving tasks
• sports-based competitions

These events are often held outside London in dedicated activity centres.

They can be excellent for team bonding, but require more travel and logistics compared with indoor activities.

What Makes a Good Team Building Activity for Large Groups?

When planning events for large teams, the most successful activities usually share a few key characteristics.

Everyone can participate
Activities should allow everyone to take part rather than leaving some people watching from the sidelines.

Clear structure
Well organised events with a clear format keep the energy high and prevent confusion.

Shared experience
Activities that involve the whole group at once often create stronger memories than events split into separate sessions.

Choosing the Right Activity for Your Team

The best team building activity depends on your team size, location and the type of experience you want to create.

If you’re organising a social event where the goal is to bring everyone together and create energy in the room, hosted activities such as game shows or quizzes often work particularly well.

Outdoor and smaller group activities can also be effective, but they may require more planning for large teams.

The Show Time Game Show Experience

Show Time’s Game Show Experience is a fully hosted TV-style team building event designed specifically for corporate groups.

The show includes five rounds:

• Spin the Wheel
• Our Survey Says
• Higher or Lower
• Right on the Money
• Carrot in a Box

The experience runs for around 90 minutes and works particularly well for groups of 20 to 120 people.

The full setup includes the Big Wheel, podiums, buzzers, lighting and a professional host, transforming offices and venues into a live game show environment.

Final Thoughts

London offers a wide range of team building activities, from outdoor challenges to interactive indoor experiences.

For large groups, the most successful events are those that allow everyone to participate and create a shared experience across the whole team.

Choosing the right format can turn a simple team event into something people will remember long after the event is over.
