One Great George Street

What One Great George Street does

One Great George Street is a Grade II listed Edwardian conference, event, and wedding venue located at 1 Great George Street in Westminster, London, operating from the headquarters building of the Institution of Civil Engineers (ICE). The venue was first used commercially in the early 1980s and rebranded under its current name in 1991. It offers 21 function rooms with capacities ranging from 6 to 400 guests, anchored by the Great Hall (394 sq m), Telford Theatre (240 fixed seats), and the Library, plus a café bar (Kendal's) operating weekday breakfast and lunch service. The venue serves corporate clients, professional associations, government bodies, charities, wedding couples, film and TV production companies, training organizers, and festive/seasonal event hosts across both UK and international markets. Its technology stack centers on an in-house audio visual team using Analog Way, Panasonic, D&B, and Allen & Heath equipment, Sennheiser and DPA microphones, Matterport-powered 3D virtual tours, and a hybrid event platform connecting physical and virtual attendees. Add-on services include in-house award-winning catering led by an Executive Chef and Head Chef, and preferred hotel partnerships with Conrad London St. James, St. Ermin's Hotel, and The Westminster London Curio Collection.

Revenue is generated through four streams: per-event room and venue hire (starting at £11,500+VAT for external-caterer weddings, quote-based for corporate hire), in-house catering (including a £120+VAT per-person Post-Wedding Celebration wedding package), AV services priced as separate packages and hourly rates, and walk-in café trade. Go-to-market is direct enterprise field sales with a dedicated event coordinator per client, supported by downloadable rate cards and brochures, an interactive floorplan, social media channels, blog content, quarterly newsletters, and a steady cadence of industry award participation (AIM Gold for 12 consecutive years, multiple Conference & Events Awards, Memcom Excellence Awards, Prestigious Star Awards, Lux Life Magazine, and the Cateys Best Accessible Venue award). The venue is wholly owned by the Institution of Civil Engineers, a UK nonprofit professional body and the world's first professional engineering society, and operates with a staff of approximately 25.
