Finding a London wedding venue for 200, 300 or 400 guests is not just a matter of looking for a large room. You need enough space for dinner, a dance floor, a drinks reception and the production behind the scenes. A venue may publish a banquet capacity that is much higher than the number it can comfortably seat once a stage and dancing are added.
These seven large wedding venues in London offer very different possibilities, from grand hotels to historic buildings and garden celebrations.
The Dorchester, Park Lane
The Ballroom: around 380 for a comfortable full wedding; 422 published for dinner and dancing
The Dorchester is one of the few hotels in this selection with a ballroom entrance directly onto Park Lane. Its Gold and Silver Rooms give a large guest list somewhere distinct to gather for the reception, while dinner takes place in the main Ballroom.
The hotel lists 422 for dinner and dancing, but the team suggested planning around 380 guests for a more comfortable celebration. For a wedding with substantial staging, the actual seating plan matters more than either headline figure.
Raffles London at The OWO, Whitehall
Whitehall Ballroom: around 400 for dinner and dancing
Raffles offers an unusually production-friendly ballroom within one of Westminster’s great historic buildings. The room can be divided into sections, with a separate reception foyer, smaller support rooms and access for deliveries by vehicle lift.
For an event with elaborate lighting and a substantial stage, that infrastructure is a real advantage. The foyer is not as generously proportioned as the ballroom at its maximum capacity, though, so the layout of a drinks reception needs its own consideration.
The Chancery Rosewood, Mayfair
Grand Ballroom: banquet maximum 510 on rounds, before a stage and dance floor are allowed for
The Chancery Rosewood’s Grand Ballroom has high ceilings and considerable flexibility for production. It can be divided, while the foyer and adjoining salons give couples options for the ceremony, family space, performers and suppliers.
The published banquet figure is not a promise of 510 guests for a full wedding with dancing. Ask the hotel to produce a single plan that includes the ceremony configuration, any turnaround, drinks reception and finished dinner-and-dance layout.
Banqueting House, Whitehall
Main Hall: up to 300 for dinner and dancing
Banqueting House is an alternative to the neutral hotel ballroom: dinner takes place directly beneath Rubens’ painted ceiling. The Undercroft provides an additional space downstairs, potentially allowing different parts of the celebration to have their own setting.
It is a historic building, however, and suppliers need to work within conservation requirements. A large guest list makes early conversations about production, room flow and access especially important.
The Hurlingham Club, Fulham
Broomhouse Suite: around 280 for dinner with a dance floor; up to 350 for dinner without one
The Palm Court and Broomhouse Suite give The Hurlingham Club a natural division between the ceremony and dinner. The Broomhouse Suite then opens onto the terrace and gardens, which is attractive for a summer wedding with a substantial guest list.
The difference between 280 with dancing and 350 without it illustrates why published capacities need context. The club also provides its own catering, rather than working on a dry-hire basis.
London Hilton on Park Lane, Mayfair
Grand Ballroom: up to 1,100 in the hotel’s banquet layout, not a dinner-and-dance count
For couples planning an exceptionally large reception, the London Hilton on Park Lane is worth looking into. The hotel has a very high banquet capacity for its Grand Ballroom and offers adjoining event and foyer spaces.
That figure does not establish how many people can dine comfortably with a large dance floor and stage. For a wedding of this size, request a plan that shows both the room and the circulation space around the production rather than relying on the hotel’s maximum alone.
Hampton Court Palace, East Molesey
Great Hall: up to 220 seated for dinner; larger marquee proposals in designated grounds
Hampton Court Palace offers two quite different routes to a large wedding. Inside, the Tudor Great Hall provides a seated dinner setting for around 220 guests, with other spaces potentially used for arrival, drinks and dancing.
For considerably larger guest numbers, the palace can allow temporary structures in parts of its grounds. This is a bespoke production proposition rather than a standard wedding package. Ask about conservation approvals, supplier access and a weather alternative before making a commitment.
What capacity should you actually compare?
Look first for dinner and dancing rather than banquet, standing or theatre-style numbers. Then check the ceremony and drinks reception separately: a venue needs enough capacity at every stage of the day, not only at dinner. Finally, ask whether the figure includes the stage, entertainment, aisles, accessible circulation and any other installations you want.
If you are still deciding which area of London to choose, our wedding locations guide offers a wider introduction. For a hotel-only comparison, see our London hotel wedding venues. Several of these hotels are on Park Lane, which we cover in our guide to Park Lane wedding venues. For a shortlist across all guest numbers, see luxury wedding venues in London.
Capacities have been labelled by layout wherever known. Do not treat banquet maxima as confirmed capacities for a complete wedding with dancing.
