Outdoor Event Planning Checklist

Outdoor events in the UK require more planning than indoor ones. This checklist covers equipment, weather contingencies, power supply, welfare facilities and everything else you need for a successful outdoor event.

Outdoor events in England and Wales demand a wet-weather plan before anything else. July remains no exception. Securing the right outdoor event planning hire equipment dictates the success of your site layout. The checklist below covers shelter, seating, power, welfare facilities, and the quantities that trip organisers up most often.

Start with shelter for outdoor event planning hire

For any outdoor gathering with more than 30 guests, a covered area for all attendees remains mandatory. At minimum, you need somewhere guests can move to if the weather turns during the proceedings. For weddings and sit-down meals, assume you need full cover from the start.

Marquee sizing guide:

  • Seated dinner: allow 1 sqm per person plus 20-25% for a catering area, bar, and any stage or dance floor
  • Standing reception: 0.7 sqm per person as a minimum
  • Mixed seated and standing: 0.85 sqm per person

For smaller events, large gazebo hire options or connected canopy systems work well. For anything above 50 guests, a proper marquee gives you more control over layout, lighting, and weather protection.

The master checklist

Shelter and shade

  • Marquee or gazebo sized to cover all guests
  • Groundsheet or matting for the marquee floor, especially on grass
  • Parasols or umbrellas for lounge and drinks areas outside the main marquee
  • Side panels for wind and rain (most marquees have these as add-ons)

Seating and tables

  • Tables suitable for outdoor surfaces (folding trestle tables and beer benches both work on grass)
  • Chairs with rubber foot pads or wider bases to stop narrow 4-leg chairs digging into soft ground
  • Tablecloth weights or clips for any tables in exposed areas
  • A hard surface under the bar and catering areas in case the ground becomes soft

Browse our outdoor event hire, chair hire, and table hire ranges for outdoor-suitable options.

Power

  • Generator or confirmed mains extension in case on-site power falls short
  • All electrical equipment PAT tested before the event
  • Cable covers or matting over any cables crossing walkways
  • Patio heater hire for evening events, planning one per 10-15 guests near seating areas
  • Fuel supply confirmed in advance for running a generator or gas patio heaters

Catering area

  • Covered prep area for the catering team, separate from guest areas
  • Wind breaks around any open burners, BBQs, or induction hobs
  • Additional staff for outdoor service because food cools faster than indoors and service needs pace
  • Ice supply at 30% more than you would order indoors because it melts significantly faster in sun or warm weather
  • Waste bins and bag changes planned for during the event, not just at the end

Welfare facilities

  • Toilets: minimum 1 per 50 guests for events under 4 hours; 1 per 35 guests for full-day events
  • Separate facilities for catering staff depending on numbers
  • Handwashing stations adjacent to toilet facilities
  • First aid kit in an accessible location known to all staff

Lighting

  • Festoon lights or LED string lights for any evening event
  • Path lighting for uneven ground, steps, or areas guests will walk after dark
  • Battery-powered options in case mains power falls short across the full site

Ground and access

  • Visit the site after rain to assess ground conditions before you commit to a layout
  • Confirmed delivery vehicle access: width, weight limit, and turning space for collection
  • Matting or flooring for the marquee entrance, catering area, and any heavily trafficked routes

Booking and delivery timeline

For summer events (May to September), book hire equipment at least 4 to 6 weeks ahead. Popular weekends in July and August book out significantly earlier, particularly for marquee packages, large furniture quantities, and outdoor heaters.

Allow a full morning for delivery and setup when receiving multiple hire orders. For larger events, request morning delivery and plan for a 4 to 6 hour setup window before guests arrive.

Confirm delivery vehicle access requirements with the hire company before the event. A large marquee delivery may require a 7.5 tonne vehicle. Some rural and residential venues need advanced notice or alternative access arrangements.

Weather contingency

Have a named person responsible for the weather call. Set a decision point, typically 48 hours before the event, at which you confirm your move to plan B. This might involve pulling down parasols, putting up extra side panels, or moving the reception inside. A clear decision point prevents last-minute panic and means suppliers and staff receive their briefings in time.

Brief all staff on the contingency plan before the event, not during it.
