3 Hanover Square

Venue hire fees range from £8,250-£28,750 + VAT depending on dates, timing, and duration, with significant reductions from rack rates of £15,000-£75,000. All quotes include exclusive access to the whole venue, but additional mandatory costs apply: cleaning fee £200 + VAT, external supplier fee £500 + VAT (if using non-approved vendors), and security at £25 + VAT per person per hour. The venue operates as a gallery during the day (10:00-19:00), so later front-of-house access times offer more flexible pricing.

The venue accommodates up to 420 guests for standing receptions across both floors. For seated events: ground floor gallery holds 100 dinner guests or 120 theatre-style, while the lower gallery accommodates 50 dinner guests or 70 theatre-style. The Director's office provides an additional breakout space for 15 seated guests with presentation facilities.

Access times vary by event type and pricing tier, typically ranging from 15:00-01:00 for evening events. Back-of-house access usually begins 3-4 hours before front-of-house access for setup. The venue is closed for Christmas holidays (December 28-29), and availability is limited during December with only select dates remaining. All events must end by 01:00 with derig completed within the access period.

Security is mandatory at £25 + VAT per person per hour. Requirements are: 2 security personnel during setup and derig periods, and 4 security personnel when the event is live. This means minimum security costs of approximately £300-600 + VAT depending on your event duration and timing.

The venue includes a 16KW sound system with wireless microphones, a 3x2m customizable LED screen in the lobby, and track lighting throughout both floors. For larger events, there's also a 6-metre custom LED screen and 32-speaker audio system available. Additional AV requirements can be arranged through approved suppliers, though this may incur the external supplier fee.

All quotes are bespoke and availability operates on a pencil system (2nd pencil, 5th pencil indicating booking priority). Due to high demand, especially for December dates, rates cannot be reduced below quoted prices. The venue requires confirmation of desired dates and timings before providing detailed proposals, and site visits can be arranged to view the space.

3 Hanover Square operates as a dry hire venue with two onsite kitchens available. All catering must be provided by external suppliers, with the venue offering a list of recommended F&B suppliers who can provide everything from bowl food and canapés to luxurious theatre dinners, custom cocktails, and open bars. Using non-approved caterers incurs a £500 + VAT external supplier fee.

Yes, the venue can be transformed into a blank canvas for production-heavy events, with this flexibility being introduced in 2025. The space features post-industrial architecture with premium finishes and can accommodate significant customization. However, any artwork removal requirements and specific production needs should be discussed during the booking process as additional fees may apply.

3 Hanover Square functions as a contemporary art gallery by day and private event space by night, providing a revolving backdrop of contemporary art exhibitions year-round. Located in picturesque Hanover Square in the heart of Mayfair, it offers 6,000 sq ft across two floors that can operate independently, combining state-of-the-art facilities with an ever-changing artistic environment.

The venue can accommodate events requiring loud music, dancing, and entertainment, making it suitable for parties and celebrations. However, as it operates as an active art gallery during daytime hours (10:00-19:00), this affects scheduling and setup times. The venue is positioned between luxury Mayfair boutiques and high-street favorites, making it ideal for upscale corporate events, private dining, and luxury brand activations.
