Best London Event Venues for 100–200 Guests

Finding the right London event venue for 100-200 guests can be surprisingly difficult. You need enough space for everyone to feel comfortable, but a venue that is too large can leave an event feeling empty and lacking in atmosphere.

The good news is that London has an excellent choice of venues designed for events of this size, from contemporary conference spaces and private members’ clubs to historic buildings, cultural venues and blank canvas spaces.

Whether you’re organising a conference, product launch, awards dinner, networking event, company celebration or private dinner, here are some of the best London event venues for 100-200 guests to consider.

1. RSA House, The Strand

Hidden just behind the Strand, RSA House is a particularly versatile option for medium-sized corporate events. The Grade II listed Georgian building combines historic character with modern event facilities and has a number of different spaces.

The impressive Great Room is particularly well suited to this size of event, accommodating up to 200 guests for a standing reception and around 120-130 for dinner, depending on the event format. The Benjamin Franklin Room is another attractive option for receptions of up to 150 guests.

For something less traditional, the atmospheric Vaults beneath the building provide an unusual setting for parties, product launches and evening events.

Best for: Conferences, dinners, receptions, awards and corporate events
Location: The Strand, WC2
Nearest stations: Charing Cross, Embankment and Covent Garden

2. The Conduit, Covent Garden

For companies looking for a contemporary London venue with a strong focus on sustainability and social impact, The Conduit is well worth considering. Located in Covent Garden, this private members’ club offers several stylish event spaces.

The Forum is the main conference and event space and can accommodate up to 150 seated delegates. It comes with integrated AV, a large video wall, bar and cloakroom, while additional rooms can be used for breakout sessions.

The venue also has spaces suitable for dinners, networking and receptions, making it a good choice when an event needs to move between different formats during the day or evening.

Best for: Conferences, panel discussions, networking, dinners and purpose-led corporate events
Location: Covent Garden, WC2
Nearest station: Covent Garden

3. 30 Euston Square

Location is often one of the biggest considerations when you’re inviting 100-200 people to an event, particularly when delegates are travelling into London. 30 Euston Square has the considerable advantage of being directly opposite Euston Station and within easy reach of King’s Cross and St Pancras.

Its State Rooms work particularly well for events within this capacity range. The Euston Room can accommodate up to 200 theatre-style or standing and 160 for a seated dinner, while the State Rooms can also be combined with the rooftop terrace for larger receptions.

Modern AV, breakout rooms, catering and accommodation are all available within the building.

Best for: Conferences, meetings, dinners, receptions and corporate events
Location: Euston, NW1
Nearest station: Euston

4. OXO2, South Bank

For an event where the setting needs to make an immediate impression, OXO2 offers spectacular views across the Thames towards St Paul’s Cathedral and the City. Located within the iconic OXO Tower, the venue comprises two interconnecting gallery-style spaces which can be used separately or together.

It can accommodate up to 150 theatre-style or 200 for dinner, making it particularly suitable for events at the upper end of the 100–200 guest range. It’s contemporary blank canvas design also means there is plenty of scope for branding, production and creative styling.

Best for: Product launches, awards, dinners, receptions and brand events
Location: South Bank, SE1
Nearest stations: Blackfriars, Waterloo and Southwark

5. Southbank Centre

For organisers looking for an instantly recognisable London location, Southbank Centre offers a number of event spaces overlooking the Thames.

The rooftop pavilions are particularly interesting for events of this size. The Weston Roof Pavilion, for example, can accommodate around 110 guests for dinner or up to 220 for a reception, while St Paul’s Roof Pavilion can host up to 150 for drinks and canapés.

The combination of cultural surroundings, central location and river views makes Southbank Centre particularly appealing for receptions, dinners and client events.

Best for: Receptions, dinners, networking and corporate hospitality
Location: South Bank, SE1
Nearest stations: Waterloo and Embankment

6. The British Library

The British Library is a useful option when you want somewhere that feels distinctly different from a hotel or conventional conference centre.

Situated next to St Pancras and King’s Cross, it is exceptionally convenient for delegates arriving from outside London. Several spaces suit events within the 100-200 guest range, including areas capable of accommodating up to 200 for receptions. AV support is available and the event spaces are wheelchair accessible.

It is particularly worth considering for academic events, corporate receptions and organisations looking for a venue with a strong cultural identity.

Best for: Receptions, academic events, corporate events and networking
Location: St Pancras, NW1
Nearest stations: King’s Cross St Pancras and Euston

7. Tower of London

If you’re entertaining international guests or need a venue with genuine impact, few London locations are as memorable as the Tower of London.

The New Armouries can accommodate up to 150 guests for a seated dinner, making it an excellent option for corporate dinners, awards and special celebrations within this guest range.

The historic surroundings create an experience in their own right, making this particularly suitable for organisations wanting to give guests a memorable sense of London.

Best for: Gala dinners, awards, corporate hospitality and special occasions
Location: Tower Hill, EC3
Nearest station: Tower Hill

What size venue do you need for 100-200 guests?

Guest numbers are only the starting point when choosing a venue. A room that works perfectly for a standing reception of 180 people may only accommodate 100 for a seated dinner. Similarly, a conference for 150 delegates may require considerably more overall space once you add registration, catering, breakout rooms, AV production and networking areas.

Before comparing venues, consider:

• Your final expected number of guests
• Seated or standing format
• Theatre, cabaret, classroom or banquet layout
• Stage and AV requirements
• Breakout rooms
• Registration space
• Catering areas
• Exhibition or sponsor stands
• Cloakroom requirements
• Accessibility
• Transport links
• Whether you need exclusive use of the venue

It is also worth thinking about event flow. For a conference, for example, having a separate area for refreshments and networking can make a significant difference to the delegate experience.

Is a 200-capacity venue too large for 100 guests?

Not necessarily. Published capacity is normally the maximum number of people a room can accommodate in a particular layout. It doesn’t automatically mean the room will feel too big with fewer guests.

A flexible venue may be able to change the room layout, use screens or staging, adjust furniture or reduce the usable footprint to create a more appropriate atmosphere.

This is one reason why it is important to look beyond the headline capacity when comparing venues.

How much does a London event venue for 100-200 guests cost?

There is no single price because London venue costs vary enormously. A straightforward meeting or conference venue may offer a day delegate rate including room hire, refreshments, lunch and basic AV.

Blank canvas venues may charge separate hire fees with catering, furniture, production and staffing added on top. For parties and receptions, some venues operate on a minimum food and beverage spend instead.

The most useful comparison is therefore not always the initial room-hire figure but the total cost of delivering the event.

Which area of London is best for an event of 100-200 guests?

For events attracting guests from across the UK, locations around King’s Cross, St Pancras, Euston, Waterloo, Liverpool Street and Paddington can make travel considerably easier.

For client entertaining, product launches and evening events, areas such as Covent Garden, the West End, City of London and South Bank offer an enormous choice of distinctive venues.

There isn’t one “best” London location. The right area depends on where your guests are travelling from, the type of event you’re organising and your budget.
