The package includes diverse street food stalls, sustainable wine selection, refreshing cocktails from the bespoke London Essence bar, and exclusive Helles Lager brewed with Braybrooke Brewery. Limited dates remain for July and August.

The Sugar Rooms consist of two interconnecting rooms - the Upper Sugar Room for main events and Lower Sugar Room for separate catering areas. The Retreat courtyard accommodates 30 to 800 guests. Other spaces mentioned include King George III, Queen Charlotte, Smeaton Vaults, and James Watt, though specific capacities for these rooms are not detailed in the available information.

Christmas dates cannot be held due to high demand and operate on a first-come, first-served basis. The venue features a new theme each December - for 2025, it's 'The Midnight Carnival' following 2024's 'Electric Flamingo' theme. Christmas parties run from 6pm in the evenings, with daytime availability from 7am until 5pm.

Security guards/fire marshals are mandatory at £395 excluding VAT per guard. The requirement is typically 1 guard per 100 guests, with multiple guards needed for larger events. For example, events with 250+ guests require 3 security guards at £1,185 excluding VAT total.

There is a minimum AV spend requirement that varies by event size and complexity. Examples from quotes show minimum AV spends ranging from £1,000 to £35,000 excluding VAT depending on the event scale and technical requirements. This covers projectors, screens, lecterns, microphones, mixers, tech support and installation crew.

Events typically run with access from 7am and can continue until 1am the following day. Christmas parties specifically run from 6pm onwards, while daytime events have access from 7am until 5pm. Setup may require access from 6-7am for larger events, and overnight holds are available for multi-day events.

The venue operates on 1st and 2nd option holds. Some dates are offered on 2nd option when another event is holding on 1st option, with updates provided soon after. For high-demand periods like Christmas, dates cannot be held and operate strictly first-come, first-served.

Catering options include standing menus with canapés, three-course seated dinners, food stall lunches, and buffet-style service. Drinks packages range from sparkling wine and cocktail receptions to unlimited house wine, beer and soft drinks for 4.5-5.5 hours. The venue also offers diverse street food stalls through The Retreat package.

Specific dates may be unavailable due to confirmed events, as seen with Wednesday 10th September 2025 being unavailable. The venue can suggest alternative dates when preferred dates aren't available. Some clients prefer avoiding Mondays and Tuesdays, with Wednesdays and Thursdays being popular choices.

Beyond base packages, budget for mandatory security guards (£395 per guard excluding VAT), minimum AV spend requirements, potential overnight holds for multi-day events, and Brewery Technical Support Managers (£900 excluding VAT).
