Ask five mobile bar companies for a price and you'll get five answers structured five different ways. That isn't evasiveness — a bar can genuinely be paid for in several different ways, and the right one depends on your guest count, your venue, your running order and whether you or your guests are buying the drinks. This guide walks through every commercial model, every factor that moves a quote, and how to compare two very different-looking prices fairly.
The six ways a mobile bar is paid for
Complimentary hire against a minimum spend: there's no hire fee at all, because the bar earns its money over the counter. You agree a realistic bar take, and if guests spend it, the hire costs you nothing. It suits larger events — typically 100 guests and up with a full evening bar — where you're confident the bar will be busy.
Flat paid hire with a guest-pay bar: you pay an agreed fee to have the bar on site and guests buy their own drinks. This is the most predictable model for smaller, shorter or daytime events where a minimum spend would be a gamble.
Hosted bar or open tab: you buy the drinks on behalf of your guests, usually up to an agreed cap, after which the bar switches to guest-pay. Common at weddings for the drinks reception and at corporate events all evening.
All-inclusive drinks packages: a per-head price covering an agreed drinks list for an agreed window. Easiest to budget for, because the number doesn't move once your guest count is confirmed.
Dry hire: you supply the stock under your own or the venue's licence and hire the bar itself, with or without our team. Cheapest on paper, but you carry the buying, the chilling, the transport and the leftovers.
Profit share: for festivals, public events and ticketed nights, we run the bar at our own risk and split the take on agreed terms. No cost to the organiser, but it only works where footfall is high enough.
What actually moves the number
Guest count is the single biggest lever. It sets how many bartenders you need, how much stock is chilled, and how much kit comes on the van. A well-staffed bar runs roughly one bartender per 50–75 guests for a standard service, and closer to one per 40 for a cocktail-led menu.
Service hours come second. A two-hour drinks reception and an eight-hour wedding day are different jobs, and the difference is mostly staff time — plus set-up and breakdown either side, which should always be quoted as part of the day rather than billed separately.
Travel matters more than people expect. Within 30 miles of base it should be included; beyond that it should appear as a stated figure on the quote, not a surprise afterwards. Overnight crew accommodation applies on very late finishes at distance.
Drinks choice changes the per-head figure considerably. Beer, wine and a couple of house cocktails is a very different stock bill to a full craft cocktail list with fresh garnish and premium spirits.
Glassware versus premium plastics, whether the venue provides power and water, late-night curfews and noise limits, marquee versus indoor set-up, and whether a Temporary Event Notice is needed all shift the total too.
Season and date carry a premium of their own. Peak Saturdays between May and September are the most contested dates in the calendar; midweek and off-peak events are consistently better value.
Which model suits which event
Weddings of 100+ with an evening bar usually land best on a minimum spend, because the bar is busy for long enough to cover itself and there's no hire fee on your budget sheet.
Smaller weddings, birthdays and daytime celebrations tend to work better on flat paid hire — you know the number up front and guests buy what they want.
Corporate events, launches and Christmas parties almost always run hosted or all-inclusive, because nobody wants staff queuing with a card at a company event.
Festivals, markets and ticketed public events fit profit share, where volume does the work and the organiser carries no cost.
If your venue insists you use their licence, dry hire is often the only option available — and it's a perfectly good one when you have access to trade pricing.
What should always be included
Professional, uniformed bartenders for the full service window, plus set-up and breakdown time either side.
The bar unit itself, delivery to site, fridges, ice, garnish, service equipment and either premium plastics or glassware where specified.
Public liability insurance, personal licence holders on site, and support with a Temporary Event Notice where your venue isn't already licensed.
A bespoke drinks menu designed around your event, agreed in advance rather than pulled off a standard list.
How to compare two quotes fairly
Put both quotes side by side and check what's actually included: staff, glassware, ice, garnish, delivery, set-up, breakdown, insurance and licensing support should all be written down, not assumed.
Check the staffing ratio against your guest count. A cheap quote with one bartender for 150 guests isn't cheap, it's a queue.
Check whether travel, overtime and late finishes are inside the price or outside it, and at what rate.
Check whether the price is fixed or indicative, and what happens if your numbers change. Ours are quoted individually and confirmed in writing.
Check for bundling. Booking the bar alongside sound, lighting or event styling from one supplier removes duplicated travel and crew, which is why our packages come in below the sum of their parts.
Common questions about mobile bar costs
Is a mobile bar cheaper than a venue bar? Usually yes on drinks pricing, and almost always better on flexibility — but the real saving is that you choose the model, the menu and the hours.
Do I pay for the bar if nobody drinks? Under a minimum spend, you cover the shortfall between what guests spend and the agreed figure. Under flat paid hire, the fee is the fee regardless.
How far in advance should I book? Peak weekends between May and September go 6–12 months ahead. Off-peak and midweek dates are often available at much shorter notice.
Is a deposit required? Yes — a booking deposit secures your date, with the balance due before the event. Terms are set out on your quote.
Getting a real number
Prices are always quoted per event, because no two running orders are the same. Send us your date, venue, guest count and rough timings and you'll get an itemised quote within 24 hours, with a recommendation on which commercial model works out best for your event — including when that means we earn less.
