For companies organising a Christmas party for 150–300 guests, London offers a wide choice of landmark venues, luxury hotels, historic buildings and unusual event spaces. The right venue will depend on whether the brief calls for a seated gala dinner, a standing party with entertainment, an exclusive themed event or a more experiential celebration.
Here are 10 London Christmas party venues currently relevant to groups in this size range for Christmas 2026:
- 8 Northumberland Avenue, Trafalgar Square
Located close to Trafalgar Square, 8 Northumberland Avenue is one of the most recognisable central London venues for large corporate Christmas parties. The venue has multiple event spaces and can accommodate everything from smaller private dinners to large-scale celebrations. Its 2026 Christmas programme includes the City of Stars concept, with themed production, seasonal dining and entertainment.
For a company with 150–300 guests, the venue is particularly relevant for a formal dinner followed by entertainment and dancing, or a more immersive Christmas party with substantial production.
- 60 Great Queen Street, Covent Garden
60 Great Queen Street is a central London Christmas party venue close to Covent Garden and the West End theatre district. Current 2026 listings give the venue a maximum capacity of around 350 guests, making it suitable for companies planning an event for 150–300 people.
Its central location makes it particularly convenient for teams travelling from offices around the West End, Soho, Holborn and the City, while the venue can work for dinner-led Christmas celebrations and larger exclusive events.
- Somerset House, Strand
Somerset House is one of London’s best-known event venues and offers several spaces for corporate Christmas celebrations. Its East Wing can accommodate up to 300 guests for a standing event, while other spaces across the building provide different options for receptions, dinners and larger celebrations.
For 2026, Somerset House is offering festive events in partnership with KERB Events and Velvet Living, including a new reception experience in the Embankment Galleries.
The combination of a central Strand location, historic architecture and contemporary event production makes Somerset House particularly suitable for companies looking for a Christmas party that feels distinctly London.
- Kent House Knightsbridge
Kent House Knightsbridge is a historic townhouse offering a more exclusive alternative to a large hotel ballroom. The venue’s 2026 Christmas concept, Showstopper, takes guests through a cinematic celebration combining a glamorous arrival, dinner, awards and an after-party.
With capacity for around 200 seated guests and up to 350 standing, Kent House works particularly well for companies looking for a premium Christmas party for approximately 150–300 guests.
- Park Plaza Victoria London
Park Plaza Victoria London offers a straightforward option for companies that want a traditional corporate Christmas party with dinner, drinks and a DJ. The hotel is only a short walk from Victoria Station and can host events for up to around 400 guests depending on the format.
For a 150–300 person company party, the venue can work particularly well where transport connections, accommodation and a familiar dinner-and-dance format are priorities.
- 30 Euston Square
30 Euston Square combines historic interiors with modern event facilities and is particularly useful for corporate events where production and guest flow need careful planning.
Its Exhibition Hall can accommodate up to 300 guests, while the State Rooms and rooftop terrace provide an alternative multi-space configuration for smaller events. The venue also offers dedicated registration and cloakroom facilities, which can be valuable for larger Christmas parties.
- Landing Forty Two, City of London
Landing Forty Two offers a very different Christmas party setting, with events taking place high above London in the Leadenhall Building.
The venue is designed for medium and large corporate Christmas parties, with capacity for up to 300 guests standing and approximately 220 for a seated dinner. The combination of panoramic London views, modern interiors, lighting and a dance floor makes it suitable for companies wanting a more contemporary Christmas celebration.
Although it is outside the traditional West End, its central City location makes it a useful alternative for companies with offices across London.
- SEA LIFE London Aquarium, South Bank
For companies looking for something more memorable than a hotel ballroom, SEA LIFE London Aquarium offers an after-hours Christmas party surrounded by marine life and underwater exhibits.
The 2026 Christmas programme is available for exclusive events, with capacity of up to 350 guests. Packages can include a drinks reception, three-course dinner, wine, entertainment and dancing.
Its location beside County Hall and close to Waterloo and Westminster also makes it practical for large corporate groups travelling from different parts of London.
- Science Museum, South Kensington
The Science Museum provides an unusual setting for corporate Christmas parties, particularly for companies looking for an experiential event rather than a conventional dinner.
The museum’s Wonderlab can accommodate receptions for up to 400 guests and dinners for up to 200. The space incorporates interactive science experiences, live demonstrations and distinctive visual features, giving event planners opportunities to build entertainment into the venue itself.
For a 150–200 person dinner or a larger drinks-led event, it can provide a memorable alternative to a hotel ballroom.
- Cutty Sark, Greenwich
Cutty Sark is another distinctive London landmark for companies prepared to travel beyond the West End. Royal Museums Greenwich states that the venue can accommodate Christmas parties for up to 400 guests and gala dinners for up to 250.
For a 150–250 person corporate Christmas party, the ship provides a completely different setting from a conventional event venue, with the opportunity to build the evening around one of London’s best-known historic attractions.
Choosing between London Christmas party venues for 150–300 guests
The biggest decision is not simply which venue has enough capacity. A 300-person Christmas party can require significantly more space than a 300-person reception once dining tables, a stage, dance floor, bars, entertainment, production and catering areas are included.
For a seated Christmas dinner, look for venues with approximately 200–250 dining capacity if your guest list is around 200, while a 300-person guest list may require a substantially larger room. For a standing party, consider how much space will remain once bars, food stations, entertainment and furniture have been installed.
It is also worth checking whether the venue offers exclusive hire, what is included in the Christmas package, the permitted finish time, sound restrictions, supplier access, cloakroom capacity and the available loading arrangements.
For companies planning Christmas parties in London for 150–300 guests, starting the venue search early is particularly important. Popular December dates can become committed well before autumn, especially for Thursday and Friday evening events.
The best venue is ultimately the one that matches the guest experience as well as the practical brief: location, capacity, catering, entertainment, production, budget and the way your team wants to celebrate.
