The In & Out Naval and Military Club London Corporate Functions & Events

The In & Out Naval and Military Club London is a historic and distinguished venue in central London, offering an impressive space to host a range of corporate functions — including meetings, conferences, presentations, workshops, and seminars.

Within this elegant venue are multiple event rooms, ranging in size from modest and relaxed to grand and luxurious. 

Depending on the type of event you’re planning, you might like to book The Coffee Room; this space is regal, sophisticated, and ideal for events with larger guest lists. 

For smaller, less formal meetings, we recommend the charming Canning Room; this delightful room is a laidback space and features plenty of coffee tables and comfy lounge chairs. 

If you’re planning a longer event, you may want to think about ordering the venue’s working lunch catering option, which will give you the choice of sandwiches, hot finger food, fruit, an assortment of desserts, and, of course, tea and coffee. 

Alternatively, you might like to book one of the venue’s convenient delegate packages, which contain all the food and resources you’ll need to host a seamless work event, including WiFi, a flipchart, lunch, AV equipment (upon request), refreshments, and stationery. 

Central and conveniently-located, this historic venue, set adjacent to St James’s Square, is close to two tube stations, which are just a short walk away — perfect for commuters.
