Great Hall at One Moorgate Place

Opened in 1970 as an elegant Art Deco extension to the original 1890 building, the Great Hall at One Moorgate Place is the largest event space within the Chartered Accountants’ Hall — a blank canvas with soaring ceilings, grand architectural details, and abundant natural light that creates a striking backdrop without being prescriptive about how it’s used. The neutral design means heavy theming, creative event production, and dramatic lighting transformations all work here, while the underlying Art Deco aesthetic ensures the room carries visual weight even when left undressed.

Capacity and Configuration at One Moorgate Place’s Great Hall

The room takes 400 standing, 270-300 theatre-style, 200 for gala dinners and banquets, and various cabaret configurations. Classroom and boardroom setups are also available — the flexibility is genuine, not theoretical. A sophisticated AV system runs throughout the space and is included in the hire, though AV technicians are mandatory for most events. The standard AV package covers a lectern, microphone, two branding screens, LCD projector and screen, push-to-talk microphones, and a fixed panel for up to five speakers. Wifi, flatscreen TV, and whiteboard round out the technical provision. Air conditioning, a dance floor, and stage are built in. Room hire is VAT-exempt — an unusual detail for a venue at this level — though VAT applies to catering and services.

Events That Suit the Great Hall at One Moorgate Place

Conferences and seminars up to 270 theatre are the Great Hall’s strongest corporate format — the AV infrastructure and professional setup create a presentation environment that feels purpose-built rather than adapted. The fixed panel for five speakers supports panel discussions and multi-presenter formats without ad hoc rewiring. Classroom and boardroom configurations offer alternatives for events where interaction matters more than stage presentation. Awards dinners and gala events for up to 200 banquet gain from the room’s proportions and the Art Deco detailing that elevates formal dining above standard function-room territory. The built-in dance floor and stage mean awards events transition naturally from presentations to entertainment and dancing without mid-event furniture rearrangement. Large-scale celebrations and wedding receptions suit the neutral canvas and late licence — the 1am cut-off with extension capability gives evening events proper duration. Product launches and press events benefit from the theming flexibility and integrated production capability. The neutral design aesthetic absorbs branding and creative builds without fighting them — a meaningful advantage over heritage rooms where ornate interiors impose their own visual identity regardless of what’s layered on top. Christmas parties find a space that transforms dramatically under event lighting — the high ceilings and Art Deco bones respond well to creative production. Guest lectures, presentations, and corporate entertaining all operate comfortably within the Great Hall’s range. The room’s versatility is genuine rather than theoretical — the same space that hosts a 270-person conference on Tuesday can run a gala dinner for 200 on Friday with a fundamentally different atmosphere.

The Great Hall’s Connection to One Moorgate Place’s Heritage Spaces

The Great Hall directly adjoins the Main Reception Room — the building’s domed, chandelier-lit centrepiece with stone columns, stained glass, and George Murray murals. The two rooms together create one of the most effective reception-to-dinner flows in the City: drinks and arrivals in the heritage space, then through to the Great Hall for the main event. The Main Reception Room holds up to 300 for standing receptions in its own right. The wider building includes the Members’ Room (Venetian bridge-style balustrade, up to 45 banquet), a purpose-built Auditorium with 107 tiered seats and dedicated AV, an Auditorium Lounge, Business Centre for up to 70, multiple meeting rooms, a boardroom for 24, and the OMP Club. All spaces sit within the same Grade II listed building.

Catering and Access

Searcys handles all catering in-house on an exclusive basis — fine dining capability across formats from canape receptions to seated banquets. The alcohol licence runs until 1am with extensions available. The venue is wedding licensed. Lift access operates throughout the building for full accessibility. Moorgate station and the surrounding City transport network place the venue at one of London’s best-connected commercial locations. Natural light through the Great Hall’s windows makes daytime conferences and afternoon events particularly effective without heavy artificial lighting.
