A mobile bar is a portable bar unit brought to any location with professional bartenders, glassware, ice, and a fully customisable drinks menu. A venue bar is a fixed installation at a function room, hotel, or pub, tied to the premises licence with a set drinks list and venue pricing. Our open bar is £6.50 per adult per hour without alcoholic cocktails and £7.50 with, for the first four hours, from 100 adults. Dry hire is quoted individually. The Sesh Bars is based in Reading and operates across Berkshire and the Thames Valley, with any travel cost shown in your quote.

02 - Cost Per Head

Real Cost Comparison.

Venue bars charge retail prices per drink. The bill depends on what guests drink and how many they have. Our open bar covers unlimited drinks from a set menu at £6.50 per adult per hour without alcoholic cocktails or £7.50 with, for the first four hours, from 100 adults. That is £26 or £30 per adult for four hours. No VAT is added on top of these rates, and pub and bar menu prices already include VAT, so the figures compare like for like.

The venue prices come from published sources. The average UK draught pint was £5.34 in April 2026 (Morning Advertiser pint price survey, May 2026). A pint of Guinness in Reading averaged £5.05 in March 2025 (rdg.today, March 2025). Cocktails start at £11.00 on the Be At One drinks menu, cost £13.75 to £14.25 at Slug and Lettuce Riverside Reading and £14.50 at the Royal Berkshire in Ascot for 2026 weddings. Slug and Lettuce Reading also lists wine from £5.65 for a 175ml glass and prosecco at £7.15 for 125ml. Its two-for-one cocktail deal brings cocktails to £6.88 to £7.13 each when bought in pairs.

Some venues sell by the bottle or by the head instead. Windsor Guildhall lists prosecco from £22, wine from £20 and champagne from £38 per bottle, plus VAT. Wokingham Town Hall charges £8.00 per head plus VAT (£9.60 including VAT) for a prosecco drinks reception. That covers a welcome drink rather than four hours of drinking.

Venue drinks bill at four drinks each, by drink mix

Venue figures include VAT. Per-drink prices are the cited figures above. Our open-bar rates have no VAT added on top, and we show them for 100 adults, the standard minimum. The half pints, half cocktails mix is (£5.34 + £11.00) / 2 = £8.17 up to (£5.34 + £14.50) / 2 = £9.92. The bottle row assumes six glasses a bottle, so £20 x 1.2 / 6 = £4.00 up to £22 x 1.2 / 6 = £4.40.

Drink mix Per drink Per head 50 guests 80 guests 100 guests
Bottle fizz or wine£4.00-£4.40£16.00-£17.60£800-£880£1,280-£1,408£1,600-£1,760

The Sesh Bars, open bar with alcoholic cocktails (4 hours) Unlimited £30.00 per adult Quoted individually Quoted individually £3,000

A venue bar can be cheaper. When guests mostly drink pints, wine or bottled fizz, the venue bill is at or below our £26 rate at four drinks each, apart from the top of the pints, wine and prosecco range (£28.60). On an even mix of pints and cocktails the venue costs more than our £30 with-cocktails rate, by £2.68 to £9.68 per head (£32.68 against £30, and £39.68 against £30). The mobile bar is cheaper for cocktail-led events, by £14.00 to £28.00 per head (£44.00 less £30, and £58.00 less £30).

The break-even point depends on the mix, not the guest count. For pints at £5.34 and cocktails at £11.00 to £14.50, the venue costs the same as our with-cocktails rate at roughly 3.0 to 3.7 drinks each: £30 / £9.92 = 3.0 drinks at the top of the cocktail range, and £30 / £8.17 = 3.7 drinks at the bottom. Above that point the mobile bar costs less. For a dry hire option where you supply your own drinks, pricing is quoted individually.

What the package includes that a venue drinks price does not show

  • Dedicated bartenders for your event
  • Bar setup and strike
  • Glassware and ice
  • A fixed budget known in advance, instead of a bill that grows with every round

Venue figures are drinks only; staffing, glassware and setup at a venue are charged separately and are not priced here. The bottle row is a lower bound for a venue bar. Mobile bar pricing from The Sesh Bars' current packages.

03 - When to Choose Mobile

When a Mobile Bar Wins.

Mobile bar hire is the better choice when you want full control over drinks, pricing, and presentation. It is essential where there is no bar: marquees, gardens, warehouses, rooftops, and private land. It is also the smarter option at venues with a bar when your guests will be drinking cocktails, or when the venue's drinks list does not match your event. For mobile bar hire in Reading, we cover Berkshire and the Thames Valley.

Outdoor or marquee events

No fixed bar exists, so a mobile bar is the only option

Weddings with a custom menu

Signature cocktails, specific wine, branded presentation

Corporate events with sponsors

Serve the sponsor's brands from a branded bar

Cocktail-led events

A fixed rate per adult beats cocktails at £11.00-£14.50 each

For wedding bar hire, mobile bars let you serve signature cocktails that match your theme, something most venue bars cannot offer. Corporate events benefit from branded bar wraps and sponsor-specific drinks menus. Garden parties and festival-style events need a bar that can go wherever the party is.

04 - When a Venue Bar Works

When the Venue Bar Makes Sense.

A venue bar is the right choice when your guests mostly drink pints, wine or bottled fizz, when the venue's drinks menu matches what you want, or when the venue contract prohibits external bars. If a venue's per-head or per-bottle price works out lower than a mobile bar quote, the venue wins on cost.

The downside is lack of control. You are locked into the venue's drinks selection, their pricing, and their staff. If the venue bar is understaffed on a busy night, your guests wait. With a mobile bar, your bartenders are dedicated exclusively to your event.

05 - How to Decide

How to Choose Between a Mobile Bar and a Venue Bar.

Ask three questions: Does my venue allow external bars? What will most guests drink, and how many drinks each? Do I want to control the drinks menu? If the venue allows it, your guests will be drinking cocktails, and you want menu control, a mobile bar is likely the better option. If your guests mostly drink pints and wine and you are happy with the venue menu, use the venue bar.

08 - FAQ

Mobile Bar vs Venue Bar FAQ.

What is the difference between a mobile bar and a venue bar? +
A mobile bar is a portable bar unit brought to your event by an external supplier, complete with bartenders, glassware, ice, and setup. A venue bar is a fixed bar already installed at a function room, hotel, or licensed premises. Mobile bars offer full menu control and follow you to any location; venue bars are tied to the premises and subject to the venue's drinks list, pricing, and licensing terms.
Is a mobile bar cheaper than using a venue bar? +
It depends on what your guests drink. The average UK draught pint was £5.34 in April 2026 (Morning Advertiser), and cocktails on published Reading and Ascot menus run from £11.00 to £14.50. Our open bar costs £26 per adult for four hours without alcoholic cocktails or £30 with (£6.50 or £7.50 per adult per hour, from 100 adults), with no VAT added on top. If your guests mostly drink pints, wine or bottled fizz, a venue bar can cost less. If many of them order cocktails, a mobile bar usually costs less. On a mix of pints at £5.34 and cocktails at £11.00 to £14.50, the with-cocktails rate costs the same as the venue at about 3.0 to 3.7 drinks each.
Can I bring a mobile bar to a venue that already has its own bar? +
Yes, but check the venue's terms first. Some venues allow external bars as long as they receive a corkage fee or minimum spend commitment. Others restrict external alcohol on their premises licence. We can advise whether your specific venue allows external bars when you enquire.
Do I need a licence for a mobile bar at a private event? +
Events where guests pay for drinks, including donations, may require a Temporary Event Notice (TEN). Licensing requirements are checked for each event, and we can arrange a Temporary Event Notice where required and agreed. We carry public liability insurance to £5 million on every booking.
What events suit a mobile bar over a venue bar? +
Marquee weddings, garden parties, festivals, warehouse events, and any venue without an existing bar are natural fits. Mobile bars also suit events at licensed venues where the host wants a custom cocktail menu, branded bar setup, or simply a fixed price per adult instead of a bill that grows with every round. Corporate events with sponsorship deals often use a mobile bar to serve the sponsor's brands.
Can a mobile bar serve the same drinks as a venue bar? +
A mobile bar can serve anything a venue bar can, and more. We carry a full cocktail menu, premium spirits, draught beer via mobile taps, wine, Champagne, and a dedicated mocktail range. Unlike most venue bars, our menu is fully customisable: you choose the drinks, the brands, and the presentation.
