Host your event at Summer in the Square, running from 8–13 July 2025 in Portman Square Gardens - normally closed to the public and open exclusively for this week-long festival. With tents, seating, and event facilities already in place, it’s a cost-effective, hassle-free option. Private hires include a roped-off marquee within the main event space, offering a dedicated area for birthdays, anniversaries, summer socials, or corporate gatherings - all while enjoying the energy of the festival around you.

Food and drink packages start at £50 per person, with a range of catering options available. Guests are free to explore festival activities running daily until 8 pm, adding even more to the experience. All private hire revenue helps fund the event, keeping Summer in the Square free and open to the Marylebone community.
