Book a 10kW PA with at least 8 wired and 4 wireless mics, two mixing consoles, plus DJ inputs and four large-format screens or a 10,000-lumen projector. Include a dedicated sound engineer and a lighting rig with programmable LED uplighters.

What power supply is needed for a 300-person party?

Demand at least a 63A three-phase supply with multiple 32A outlets for DJ decks and lighting. If your total load exceeds 20kW, arrange a backup generator. Confirm power plans with the venue’s technical team two months before.

How many toilets should a 300-person event venue have?

UK guidelines recommend one toilet per 75 guests. For 300 people, provide at least four female cubicles and two male cubicles plus two urinals. Consider hiring portable units if the venue’s facilities fall short.

How can I ensure crowd comfort for 300 guests?

Maintain 10–15 air changes per hour with climate-control HVAC. Create breakout zones (around 10% of total floor area) for socialising and install clear wayfinding signage. Staff at a 1:50 ratio for efficient service and safety.

How long in advance should I book a West End party venue for 300 guests?

Secure your venue 6–9 months ahead to access the best dates and negotiate terms. Pay a 25% deposit on booking, confirm final guest numbers three months out and settle the balance four weeks before your event.

How central should a West End venue be for 300 attendees?

Choose a location within 0.2–0.5 miles (5–10 minutes’ walk) of Leicester Square, Covent Garden or Piccadilly Circus. This ensures easy arrival via Tube, bus and night-tube lines, and keeps post-event taxis under £10 for most central zones.

What licences are required for a 300-person West End party?

A premises licence covering late-night alcohol, live music and dancing is essential. A Temporary Event Notice isn’t suitable for events over 499 guests. Apply to Westminster City Council 6–8 weeks ahead and ensure your venue’s existing licence meets your hours.

What is the typical hire cost for a 300-person party venue in West End?
