The complete Christmas party marquee kit list
A summer marquee list and a Christmas one share a shape, but winter adds four problems money has to solve: mud, dark, cold and coats. Here is the checklist for a 150-guest office party.
A 150-guest Christmas party marquee typically needs: a 40m-class marquee with an insulated lining and hard floor, trackway for the access route (near-certain in winter ground), a 60kVA generator sized to cover heating as well as lights and music, 25kW-per-100sqm indirect heating, a cloakroom with coat rails for 150 coats, festive interior lighting plus safety lighting on the exit route (it is dark by mid-afternoon in December), 3 toilets plus 1 accessible, a 5m bar, and linens and tableware for a seated meal. Typical hire budget: £8,000 to £18,000 before catering, with many suppliers discounting 15 to 25% against summer rates.
The kit list, line by line
Worked at 150 guests. Every line links to the full category guide with prices.
| Item | Quantity logic | Notes |
|---|---|---|
| Marquee (insulated lining + hard floor) | 1.4 sqm per guest → 40m-class for 150 | Insulated roof lining and a raised boarded floor are what keep it warm, not the heater alone |
| Trackway | Gate-to-marquee distance, near-certain in winter ground | Book alongside the marquee; a wet December field will not wait for a rethink |
| Generator | From the load list including heaters: typically 60kVA at 150 | Heaters pull more than lights and music combined; size for both |
| Heating | 25kW indirect per 100 sqm of lined marquee | Indirect (ducted) heaters keep exhaust fumes outside the tent |
| Tables | 1 round per 8 guests → 19 at 150 | Round tables for a seated Christmas dinner format |
| Chairs | 1 per guest | Chair covers or throws lift a hired chair for the occasion |
| Dance floor | 0.2 sqm per guest → 30 sqm at 150 | Needs the same level boarded base as the rest of the floor |
| Cloakroom (coat rails) | 1 rail per 25–30 coats → 5–6 rails at 150 | The item most first-time organisers forget entirely; coats fill a marquee corner fast |
| Lighting | Festive interior rig + safety lighting on car park, toilet and exit routes | Sunset is mid-afternoon in December: guests arrive and leave in the dark |
| Toilets | 1 per 50 guests with a bar → 3 + 1 accessible at 150 | Insulated or heated units are worth the upgrade in December |
| Bar unit | 1m of frontage per 35 guests → 5m at 150 | A mulled wine or hot toddy station earns its keep at the door |
| Linens & tableware | Cloth per table, setting per guest, +10% napkins | Festive linen colourways book out early in November and December |
Why winter changes the list, not the shape of it
The event itself, a seated meal, a bar and a dance floor for 150 people, is the same brief as any other private or corporate marquee party. What changes is everything underneath it: the ground is wetter, the generator has to carry a heating load on top of lights and music, the marquee needs an insulated lining rather than just a roof, and the day is short enough that guests arrive and leave in the dark either side of the party.
Trackway is the line most likely to be skipped by someone working from a summer checklist and the most likely to be needed: after a wet November or December, a gate-to-marquee route that was firm in July can be a bog by the time the caterers, the marquee lorry and the toilet servicing tanker all need to use it in the same week.
The three things first-timers miss in December
Cloakroom space. A hired coat rail holds roughly 25 to 30 coats, so 150 guests need five or six of them, plus the floor space to put them where they do not block a fire exit or eat into the dance floor. It is a cheap line that is very easy to forget until 150 coats are piled on a chair.
Exit lighting and timing. Sunset in the UK is mid-afternoon through December, so a marquee that looked bright and welcoming on a site visit in September needs its own lit route from car park to entrance, and from marquee to toilets, agreed and installed before the first guest arrives. If the venue is rural, a taxi marshalling point with its own light and signage saves the last hour of the night from becoming the only stressful part.
Heater sizing that accounts for the whole load. A generator specified from lighting and a PA alone will brown out the moment the heaters cycle on. Give the supplier the heater kW figures, not just "the usual," and let them size the set from the combined load, not a guess.
What it costs, honestly
For 150 guests, a full Christmas party marquee (lined and heated structure, trackway, generator, furniture, dance floor, cloakroom, lighting, welfare and bar) typically runs £8,000 to £18,000 before catering and drink, with the marquee and heating together usually the largest share. Many marquee and site services companies discount 15 to 25% against their summer rates for December work, since it is their quieter season outside the party weeks either side of Christmas itself.
The same consolidation logic applies as any other event: a site services supplier covering trackway, generator, heating and toilets from one visit is fewer deliveries onto ground that is already carrying more traffic than it wants to in winter.
Christmas party marquee: the questions that follow
How much does a Christmas party marquee cost for 150 guests?
Typically £8,000 to £18,000 before catering and drink, covering a lined and heated marquee, trackway, generator, furniture, dance floor, cloakroom, lighting, toilets and bar. Many suppliers discount 15 to 25% against summer rates for December bookings.
Do I need trackway for a winter marquee party?
Assume yes unless the site has hardstanding all the way from the gate. UK ground in November and December is routinely too soft for a marquee lorry, a catering van and a toilet servicing tanker to all cross safely, and trackway is far cheaper than a stuck vehicle on the day.
How is the generator sized for a heated marquee?
From the full load list, not guest count alone: heaters typically draw more power than the lighting and PA combined, so the supplier needs the heater kW figure as well as the standard lighting and music load to size the set correctly, usually landing around 60kVA for 150 guests with heating included.
What do people forget when booking a Christmas party marquee?
Cloakroom space is the most commonly missed line: a coat rail holds roughly 25 to 30 coats, so 150 guests need five or six rails and the floor space to site them. Safety lighting on the exit route is the second, since guests arrive and leave in the dark through most of December.
