Marquee Weddings in More Depth: Flooring, Power, and Wet-Weather Planning

Choosing a venue type covers marquees as one option among several; this goes into the infrastructure questions specifically, because a marquee is the one venue type where you're essentially building a temporary building from scratch rather than hiring a finished space - and that brings decisions an indoor venue simply makes for you.

Flooring is not optional, whatever the ground looks like in July. Grass that looks perfectly firm during a site visit can turn genuinely difficult underfoot after a wet week, and UK weather makes no promises about your specific date. A proper flooring system - not just a groundsheet - matters for guests walking in heels, for accessibility (see accessibility considerations), and for protecting the marquee company's own equipment. Budget for it as a near-certain cost rather than a contingency you might skip.

Power needs planning further ahead than most couples expect. A marquee in a field usually has no mains supply, which means generator hire - and a generator sized correctly for catering equipment, lighting, a band or DJ rig, and heating all running at once, not just enough for a few string lights. Ask your marquee supplier or caterer directly what load you're planning for; undersizing this is a genuine on-the-day failure risk, not a minor inconvenience.

Heating and lighting matter more in a marquee than almost anywhere else, because you're entirely responsible for both rather than inheriting a building's existing systems. A summer marquee wedding can still get cold once the sun goes down, particularly in the evening in a British summer that isn't reliably warm after dark - patio heaters or proper marquee heating are worth budgeting for even for a July date, not just fully winter weddings.

On wet-weather planning specifically: have an actual plan, not just hope, for guest arrival in the rain - covered walkways from parking to the marquee entrance, umbrellas on hand, and a groundsheet or matting at the entrance itself to stop the first few metres of marquee floor becoming mud-tracked within the first hour. Winter weddings in the UK covers the colder end of this in more depth, but rain contingency genuinely applies to any UK date, any season.

What I'd actually do: ask your marquee supplier directly what's included versus what you need to separately hire (flooring, lighting, heating, and generator are the ones most often assumed rather than confirmed), and get all of it confirmed in writing well before your final headcount is due.
