New to improv?

If you’ve not done any improv at all before and want to try it out, there are a few places we can recommend. Although improv performances are made up on the spot, improv generally works on some loose principles that are well worth understanding before you put yourself in front of an audience. Going to a class/session will help you meet lots of people who have the same desire as you and give you a safe space to find out what its all about. You’ll hopefully have a lot of fun with it too.

Check out classes from these guys



  • Brilliant improvisers who weave witty and hilarious long-form comedy out of thin air

  • C3467X have energy popping out of their ears. Watching a show is like having The Wire/Downton Abbey/The Muppets simultaneously and intravenously fed to you. They are a one-of-a-kind gang of improvisers, so unique no words can describe them; better left to a mash of numbers and letters: C3467X.

    Ella Jean
  • Go to this new improv night in Camden! Went the other week. Didn’t think it’d be my ‘thing’ but LOVED it.

  • Genuinely one of the best improv nights in the UK

    Do Not Adjust Your Stage
  • Yada Yada is a wonderfully warm, funny night at the Camden Head. They consistently show London’s best improv comedy which, on an evening, could be anything from an improvised musical or a made-up fairy tale based on your suggestions. If you’re looking for a fun, open interesting, welcoming night out which showcases diverse talent see this – it’s is guaranteed to move you AND make you laugh.

  • Lost my voice a little bit from laughing and cheering so hard.

  • Will be making this a regular highlight in my calendar. Go!

  • Yada Yada K is a night of London’s best improv comedy acts, in a weird shaped room, on a tiny stage. What’s not to love? With the audience getting the chance to join in on stage it ends up more like a rabble of friends than a crowd of strangers. It’s like a warm custard hug.

    Lewis Harrison Barker

  • A great new night with a warm, enthusiastic and inclusive atmosphere, big crowd, decent acts and a red curtain. And beer.

    Dave Waller
  • Yada Yada K is a great improv comedy night in London. Why great? Performers go to the limit and beyond. Lovely welcome. Upforit Audience! Bam
