For daytime events, try the historic Nash Conservatory, a 19th-century glasshouse in Greek temple style, with space for 200 theatre-style.
The Trafalgar Hotel
The Trafalgar in London has doubled the size of its rooftop Vista bar. Total capacity is 200 and the al fresco space has been furnished with monochrome furniture and splashes of pink throughout.

The Terrace, Jumeirah Lowndes Hotel
For small events in the heart of the city, try the Belgravia hotel's Terrace restaurant, which opened for private hire for the first time this year. It is available between May and September for up to 60 delegates to enjoy al-fresco dining.

Former corporate clients using the venue include Lloyds Banking Group, Orient Express and EDF Energy.
AUTUMN AND WINTER
Tucked away in Mayfair, Rocco Forte's historic London property has a variety of cosy spaces to welcome delegates in the colder months.

For a more indulgent affair, the 60-delegate Roosevelt Room's features include ornate ceilings, chandeliers, high windows and antique furnishings.
Sea Life London Aquarium
Make the most of rainy days with a water-themed event at Sea Life London Aquarium. Ideal for large events, it can hold up to 500 for cocktails across its various zones, where delegates can view more than 500 species of marine life, including sharks, rays and penguins. Areas can also be booked for smaller events, with space for up to 200 for sit-down dinners. Highlights include the refurbished Shark Walk.
Gladstone Library, Royal Horseguards Hotel

The space can be interconnected to The Reading and Writing Room to hold up to 450.
With event space both above and below deck, the three-masted ship is ideal for turn-of-the-season events in Britain's changeable climate. The maritime icon relaunched this year, fully restored following a fire in 2007. All three decks will be available for exclusive hire from October onwards, in addition to a new space in the dry berth. Now raised 3m above the dock, a 1,000m2 gallery directly beneath the ship's hull can hold more than 200 for dinner or 300 for receptions.
Ideal for small groups, the Gore Hotel provides a cosy 19th-century setting near Hyde Park.
