Mobile bar hire in London costs from £350 for a dry hire setup to £6.50–7.50 per person per hour for a full all-inclusive package. The Sesh Bars publishes its pricing openly so you can budget accurately before you enquire. No surprise quotes, no hidden fees. Here is the complete breakdown.
Mobile bar hire in London costs from £350 for a dry hire setup (bar unit, licensed bartenders, glassware, and ice — you supply the drinks) to £6.50-£7.50 per person per hour for a fully all-inclusive package covering premium spirits, cocktails, beer, wine, soft drinks, and all equipment. A typical 80-guest party over four hours costs £2,080-£2,400 all-inclusive. Cash bar packages start from £500 with a £1,500 minimum guest spend. All prices exclude VAT and travel is included inside the M25. This guide covers the full cost breakdown, budget examples by event type, mobile bar vs venue bar cost comparisons, seasonal pricing variation, and regional pricing notes for London and Berkshire. For structured package details, see the packages and pricing page.
Four mobile bar hire pricing models cover every event type. Dry hire is the lowest entry cost — you supply the drinks and we bring everything else. Cash bar transfers the drinks cost to your guests but requires a minimum spend commitment. All-inclusive is the most common choice for private parties: one price covering the bar and all drinks. Bespoke pricing applies to complex multi-bar events, festivals, and large corporate bookings.
| Package | Price | What's Covered |
|---|---|---|
| Dry Hire | From £350 | Bar, staff, glassware, ice — you supply drinks |
| Cash Bar | £500 + £1,500 min | Guests pay per drink, TEN required |
| All-Inclusive | £6.50–7.50/pp/hr | Full bar, drinks, staff, glassware, setup |
| Bespoke | From £1,200 | Multi-bar, festivals, large corporate events |
All prices exclude VAT. Travel included inside M25. Final quote depends on guest count, duration, and specification.
Guest count is the biggest cost driver for all-inclusive bookings — more guests consume more drinks and require additional bartenders. Event duration adds cost linearly: a six-hour wedding bar costs more than a four-hour party bar for the same guest count. Drink specification affects price meaningfully — a prosecco and beer menu costs less than a full premium cocktail list with top-shelf spirits.
Venue access affects logistics cost. Events requiring equipment up flights of stairs, through narrow corridors, or across long distances from a van parking point take longer to set up and sometimes require additional crew. Outdoor events on uneven ground or without mains power add equipment costs (levelling boards, generators). All of these are declared in the quote — not added after you've agreed.
Private parties (house parties, birthdays, garden parties) typically suit an all-inclusive package — one price, no shopping, no running out. Dry hire works best when you already have a drinks supply or a specific brand you want served. Cash bar suits large events (over 100 guests) where the organiser is not covering the full drinks bill.
Birthday, house, garden parties
80 guests, 4hrs, champagne reception
200 guests, outdoor, generator-ready
Venue bars in London charge per-drink prices that add up quickly for larger events. A mobile bar with an all-inclusive package gives you a fixed per-head rate with unlimited drinks — no running total, no surprise bill at the end of the night. Here is how the two models typically compare for a 80-guest, four-hour event.
| Cost Item | Venue Bar | Mobile Bar (All-Inc) |
|---|---|---|
| Cocktails (3 per guest) | £2,880–£3,360 | Included |
| Wine (2 glasses per guest) | £960–£1,280 | Included |
| Soft drinks | £160–£320 | Included |
| Bartender service | Venue staff | Included |
| Glassware | Venue stock | Included |
| Corkage fee | £5–£15/bottle | N/A |
| Estimated total | £4,000–£5,000+ | £2,080–£2,400 |
Venue bar prices based on typical London event venue rates. Mobile bar pricing at £6.50/pp/hr, 80 guests, 4 hours.

The Sesh Bars' package prices stay consistent throughout the year. However, seasonal demand affects availability and venue costs — which in turn affects total event budgets. Understanding the London bar hire calendar helps you plan a cost-effective event.
Peak season (May–September): Wedding and garden party season. Saturday evenings book out 3-6 months ahead. Venue hire costs in Central and West London are at their highest. Fridays and Sundays offer better value with the same bar hire pricing.
December: Christmas party season creates a second demand spike. Corporate bookings dominate weekday evenings. Saturday slots in Zone 1 fill by October.
Off-peak (January–April, October–November): Best availability and widest venue choice. Ideal for engagement parties, milestone birthdays, and corporate events where date flexibility exists.
Bar hire pricing is consistent across London — there is no surcharge for South London, East London, or North London events. Travel is included for all venues inside the M25. Weekend evenings in Central London (W1, WC2, EC2-EC4) carry a £75 surcharge to cover extended parking and Congestion Charge.
Berkshire events (Reading, Windsor, Ascot, Maidenhead, Newbury) carry a mileage supplement of £0.50 per mile beyond the M25. For a wedding in Windsor, this typically adds £15-£25 to the quote. UK-wide bookings are available on request with a bespoke travel supplement.
A 5-hour wedding reception costs roughly £3,250–£3,750 all-inclusive for 100 guests. Compress it to 4 hours and costs drop to £2,600–£3,000 — a £600–£750 saving. This works for events with clear flow: champagne reception (30 min), dinner (90 min), dancing/cocktails (60 min) = 4 hours total. Evening receptions (6pm–10pm) naturally fit 4-hour windows; afternoon events often require 5–6 hours due to ceremonies ending earlier.
A beer, wine, and prosecco menu costs £5.50–£6.50/pp/hr versus £6.50–£7.50/pp/hr for a full premium cocktail list with top-shelf spirits. For 100 guests over 4 hours, this saves £200–£400. Bar staff count also drops: beer-and-wine service requires 1–2 bartenders; cocktails need 2–3. Ideal for lunch receptions, outdoor daytime events, or intimate dinners where lighter service suits the vibe.
Tuesday–Thursday bookings May–September cost the same as Saturdays at The Sesh Bars, but venue hire drops 20–40%, and accommodations (timings, catering) are more flexible. January–March sees lower bar hire demand — while pricing stays consistent, crew availability is higher and you can negotiate add-ons (premium champagne, extra staff hours) into the quote. Winter weddings (Nov–Feb) cut overall event costs by 15–25% compared to summer.
A dry hire package (£350–£450) plus your own curated spirits list (vodka, gin, rum, whiskey, mixers) costs £700–£1,200 total for a 40–80 guest event versus £1,200–£1,600 all-inclusive. You control spirit brands (buy mid-range instead of premium) and wine selection (shop around independent merchants rather than venue suppliers). Requires advance planning and procurement, but delivers 25–40% cost savings for budget-conscious hosts.
A 60-guest event typically needs 2 bartenders + 1 bar back (£500 for 4 hours). Reduce to 1 bartender + 1 bar back (£320) if your event is lower-intensity (garden party, intimate reception) and guest expectations are relaxed. Queue times extend slightly (2–3 min vs 60 sec) but guests rarely mind at casual events. Saves £180–£200 per booking.
If your caterer already supplies wine and beer, hire bar staff only (£180–£220 per bartender, 4 hours = £360–£660 for two staff) to manage drinks service. Coordinate beverage timing with meal service to avoid bar congestion. Combines speed (they focus only on drinks) with cost savings (no full bar unit or glassware hire). Works best for sit-down dinners where drink service is scheduled rather than continuous.
Real example: A couple planning a 70-guest wedding on a Thursday in March could save £800–£1,200 by: (1) compressing 5-hour service to 4 hours (save £150–£250), (2) choosing beer/wine over cocktails (save £200–£300), (3) booking a winter wedding in off-peak season (venue savings, not bar-related but worth considering), and (4) dry hiring and sourcing their own spirits (save £400–£500). Total combined savings: £750–£1,050. Call us to explore which optimizations fit your event without sacrificing quality.
Generator hire is the most common add-on: if your venue or outdoor site has no mains power, expect an additional charge of £80–£150 depending on generator size. Mileage supplements apply to events outside the M25 — London venues are always included. Event extensions past the agreed end time carry an hourly rate agreed upfront in the contract.
A Temporary Event Notice (TEN) costs £21 and is required for cash bar events at venues without a premises licence. Applications need at least 10 working days — do not leave it late. Premium Champagne upgrades (Moët, Veuve Clicquot, Laurent-Perrier Rosé) are the other common upgrade beyond the standard quote. All of the above are declared before you sign. See the full pricing page for itemised add-on rates.
Bar service typically accounts for a meaningful slice of a London wedding or corporate event budget, but it drives a disproportionate impact on how guests experience the day. Unlike a vendor that touches the event once, the bar touches every guest repeatedly over the four to six hours of the event, creating persistent impression points. A polished mobile bar with professional bartenders becomes part of your event's visual identity — it shows up in candid photos and videos, it's a hub for guest conversation, and it's often remembered afterwards as a marker of how well the event was run. In our experience running 900+ events, the quality of the bar is one of the details guests comment on most.
Beyond the guest experience, professional bar service brings tangible operational benefits: faster guest flow (our standard is queues under 90 seconds rather than the long waits common at understaffed or self-serve bars), more time for guests to mingle and dance instead of queueing, and fewer logistical delays — a well-staffed bar keeps the evening running to schedule. For London couples and corporate planners managing tight reception timelines, that matters: a wedding that stays on schedule avoids overtime vendor charges, keeps momentum through the formal moments (first dance, cake cutting, speeches), and delivers a tighter experience that guests perceive as better organised. As a guide, mobile bar hire for a 100-guest event typically lands around £2,000–£3,500 — a modest share of total event spend for something guests engage with all night. That value-to-cost ratio is why more and more London couples and event planners choose a professional mobile bar: it's a high-leverage investment in the overall event experience.
