How Much Money to Put Behind the Bar at a Wedding?

If you are deciding how much money to put behind the bar at a wedding, begin by choosing which drinks you want to host and for how long. In the UK, many couples provide a welcome drink, wine with the meal and a toast, then let guests buy further drinks at a pay bar. This gives guests a generous experience without making the final bill impossible to predict.

For planning purposes, a 100-guest example using 2025 UK benchmark figures comes to about £2,700 for those hosted moments. A two-hour capped period could add roughly £1,200, bringing the total to about £3,900 before staffing or venue charges. These are illustrations, not fixed prices.

What does putting money behind the bar mean?

Putting money behind the bar normally means prepaying a tab or agreeing a hosted package. It does not have to mean unlimited drinks all night. You can set a fixed amount, pay for selected moments, or cover a defined time window. Once that allowance ends, the venue can switch to a pay bar.

Guests generally understand paying for evening drinks when the couple has provided drinks during the reception and meal. Explain on your wedding website or information card whether the bar is cashless and when guests begin paying. Offer alcohol-free beer, wine, soft drinks and mocktails throughout.

A simple way to set your budget

Break the budget into three parts: hosted drinks, any open-bar period, and service costs. Start with guest numbers and planned drinks, then allow for a controlled window, such as one drink per guest per hour. Finally, ask about staffing, glassware, ice, setup, clear-down, VAT, service charges, corkage and travel.

For 100 guests, a typical illustration could look like this: two welcome glasses at about £6 each total roughly £1,200; half a bottle of house wine per guest at about £18 a bottle is about £900; and a £6 toast drink adds around £600. A two-hour open bar at one drink per guest per hour, using a £6 average drink price, adds roughly £1,200, giving a planning total of about £3,900 before staffing or venue fees.

An open bar for three to four hours after dinner is often estimated at £1,000 to £2,000 for 100 guests when the menu is limited, but staff may be extra. Venue prices can be higher than pub averages, particularly in London or at exclusive venues.

Three ways to structure the bar

Host the key moments, then run a pay bar

This is predictable for many UK weddings. You cover a welcome drink, wine with the meal and a toast, then guests pay for evening drinks. It keeps the shared moments generous without funding the whole night.

Offer a limited open bar

Host drinks for a short period, such as the reception or first two hours of the evening. Keep the menu focused on beer, wine, soft drinks and one or two signature cocktails. A fixed number of tokens can be fairer than an open tab because every guest receives the same allowance. Agree in advance what happens when a spending cap is reached.

Fund a full open bar

A fully hosted bar is welcoming but hardest to predict. House brands, single measures, no shots or doubles, and a clear closing time can help. Check for a minimum spend, service charge or overtime rate before committing.

How to make a capped bar feel fair

An unexplained cap can make guests rush or feel surprised when the arrangement changes. Tell people what is included and when the pay bar begins. For example: “We’re hosting welcome drinks, wine with the meal and a toast. A card/contactless bar will be open for additional drinks from 7pm.”

Tokens can cover a beer, glass of wine, soft drink or single spirit and mixer, while preventing a few early orders from using the whole budget. Make sure the bar team knows the rules and that guests can see the alcohol-free choices.

When a mobile bar is the better option

If your venue does not have a suitable staffed bar, a professional mobile bar for weddings can help coordinate the setup. Ask whether the quote includes bartenders, the bar unit, glassware, ice, mixers, clear-down, card payments, insurance and licensing support. A dry-hire arrangement may let you buy alcohol yourself, while an all-inclusive package may combine drinks and service. Compare the full cost, not just the headline fee.

For a barn, marquee or other unlicensed site, ask the venue or bar provider whether a Temporary Event Notice or other permission is needed. Requirements differ by location and by whether alcohol is sold or supplied, so confirm this early.

Ways to keep the bill under control

Beer and wine usually cost less than a full spirits menu. One or two signature cocktails add personality without a large stock of bottles and mixers. If the venue allows outside alcohol with little or no corkage, buying your own stock may reduce the bill, although you will still need staff and equipment. An off-peak date, a shorter hosted window and venue-supplied glassware can help. Budget for good alcohol-free drinks too.

Questions to ask before signing

• Is the quote based on a per-person price, a per-drink tab or a minimum spend?

• Does it include VAT, staff, setup, clear-down, glassware and ice?

• Are corkage, travel, equipment or late-night fees charged separately?

• Who is responsible for buying alcohol, mixers, garnishes and soft drinks?

• Is the bar cashless, and what licensing and insurance does the venue require?

There is no single answer to how much money to put behind the bar at a wedding; it depends on your guest list, venue and priorities. For most couples, host welcome drinks, meal wine and the toast, then run a card bar, with a short capped period if the budget allows. Get a written quote separating drinks, staffing, setup and extras, and tell guests how the bar will work before the day.
