Things to Do in in London in September

Book A Guided Walking Tour

This post is our list of the best things to do in London in September, including free, family-friendly, as well as nighttime activities, updated for 2021.

Let's get started!



If you are considering visiting many top attractions, taking a cruise, or a bus tour, then you should consider a tourist discount card or a bus tour combo ticket

These tickets and bundles could save you some serious money.

London is full of music venues and you can be sure that no matter which month you’re in town there will be a big-name artist or group performing.

This September is no different, with multiple big tours coming through London.

Take a look to see all the concerts happening in London.

2) See a Sporting Event

3) Go to a Comedy Show

Although theatrical shows might be starting back up around this time, schedules are still up in the air due to the pandemic.

One thing we do know for sure is that there are a few comedians scheduled to make an appearance in London during September, including a rare opportunity to see Trevor Noah.

London is well-known for attracting the best design companies and talent.

The LDF showcases designers from around the globe and allows London the chance to show-off its status as a leader in the creative industries.

Expect talks and lessons, tours, and exhibitions, as well as special events at museums and galleries all around London. 

Many of the events and gallery showings are free to attend! You can find events from September 18th-26th, 2021.

9) BBC Proms & Proms in the Park 2021 

BBC Proms is famous for providing lots of high-quality classical and contemporary concerts at an affordable price.

10) Save with a Tourist Attraction Discount Pass 

You can save both time and money by getting a tourist discount pass for your trip to London! Passes work by bundling entry tickets to multiple attractions or tours and passing the discounts on to you.

This means you can get into some attractions for free, and many will have a 20% or 50% discount depending on the pass.

Most of these passes include skip-the-line entry, which will save you valuable time waiting in line.
