Birthday Party Bar Hire London.

Birthday party bar hire in London starts from £850 all-inclusive for up to 35 guests.

01 — What's Included

What Birthday Bar Hire Includes.

Every birthday bar hire booking includes a mobile bar unit, a licensed bartender, a bespoke cocktail menu, quality glassware, ice, garnishes, and full setup and strike. We arrive 60 minutes before your first guest so the bar is ready when the party starts. All waste and equipment leaves with us.

All-inclusive packages cover spirits, mixers, beer, wine, soft drinks, and a non-alcoholic cocktail option as standard. Champagne and prosecco toasts are available as add-ons for milestone moments. Dry hire is available from £350 if you're supplying the drinks yourself. Public liability insurance and personal alcohol licences are included on every booking at no extra cost.

02 — Cocktail Menu

Birthday Party Cocktail Menu.

Birthday parties consistently call for big, crowd-pleasing cocktails. Our most-requested birthday menu runs the Espresso Martini, Pornstar Martini, Aperol Spritz, Velvet Bramble, and a house G&T. We batch the most popular serves so the queue never backs up — a birthday bar should feel effortless, not like a slow pub.

For milestone birthdays — 30th, 40th, 50th, 60th — we design a named signature cocktail for the guest of honour. Named after them, built around their favourite flavours, printed on the menu card. Non-alcoholic cocktails are included as standard so every guest has something worth celebrating with. See our full cocktail menu for drinks, prices, and seasonal options.

03 — Milestone Birthdays

30th, 40th, 50th Birthday Bars.

Milestone birthdays justify a proper upgrade. For 30ths and 40ths in hired London venues — Shoreditch warehouses, Brixton arches, private dining rooms in the City — we size the bar setup to the space and match the drink selection to the crowd. Larger guest counts (80–150) include two bartenders and a bar back as standard.

50th and 60th birthday packages often include a champagne or prosecco reception on arrival followed by a full cocktail bar through the evening. We coordinate the drinks schedule to match your event timeline — welcome drinks, dinner service, and dancing-until-close all have different pace requirements. See our house party bar hire page if you're hosting at home.

04 — Venue Ideas

London Birthday Venue Ideas.

The best birthday venue depends on your guest count and vibe. For 20–40 guests, a house party with our compact indoor bar works perfectly — living rooms in Clapham, Balham, and Brixton are our most-booked residential birthday setups. For 40–80 guests, a hired hall or function room gives more space — community halls in Islington, Hackney, and Camberwell offer good value and flexible access.

Summer birthdays suit garden party setups — large gardens in Richmond, Dulwich, and Hampstead with enough space for a bar, seating, and a dancefloor under a marquee. For premium milestone birthdays, rooftop venues in Shoreditch and Bermondsey, private dining rooms in Soho and Mayfair, and warehouse conversions around London Fields and Victoria Park all work well with our full mobile bar setup. Planning a wedding bar alongside a birthday celebration? We handle both.

We've served birthday bars at The Hoxton Basement, Hackney Wick warehouse spaces, The Ivy private rooms, garden venues near Kew, pubs with function rooms across South London, and rooftop terraces overlooking Tower Bridge and the Shard. If your venue has its own bar but you want our cocktail menu and professional bartenders, we can staff it directly — see our bar staff hire page.

08 — FAQ

Birthday Party Bar Hire FAQ.

How much does birthday party bar hire in London cost? +
Birthday party bar hire in London starts from £850 for a four-hour all-inclusive package for up to 35 guests. Events for 50–100 guests range from £1,300 to £2,800 depending on the drinks menu, duration, and bar configuration. Dry hire — bar unit, bartenders, and glassware only — starts from £350 if you supply the drinks.
Can you do a surprise birthday party bar setup? +
Yes. We can coordinate a silent setup before guests arrive — no early arrivals spotting the bar before the birthday person. Share your venue access time when you enquire and we'll schedule arrival and build to fit. We've set up inside hired halls, garden marquees, and private members' clubs for surprise events across London.
What cocktails are most popular for birthday parties? +
Espresso Martini, Pornstar Martini, and Aperol Spritz top our birthday bookings consistently. For milestone birthdays — 30th, 40th, 50th — we often create a named signature cocktail for the guest of honour. Champagne and prosecco toasts are available as add-ons to any birthday package.
Can you cater for a birthday party at a hired venue rather than a house? +
Yes. We've served at hired halls, private members' clubs, rooftop bars, garden venues, and restaurants across all 32 London boroughs. For venues with their own bar, we operate alongside it or staff it directly — see our bar staff hire page. For dry venue hire spaces, we bring the complete mobile setup.
Do you need mains power for a birthday party bar setup? +
Our bar units can operate on a standard 13 amp UK plug socket — most houses, halls, and hired venues are covered. For outdoor setups without mains access, we hire in a generator. Power requirements are confirmed when you send your enquiry.
How many guests can you serve at a birthday party? +
We serve birthday parties from 20 to 300 guests. For 20–50 guests, one bartender handles the bar independently. At 50–100 guests, we add a second bartender. Above 100, a head bartender coordinates the crew with bar backs for restocking. The largest birthday events we've staffed used three bar points with six staff across a warehouse venue in Hackney.
Can you create a custom cocktail for the birthday person? +
Yes. We design a named signature cocktail built around the birthday person's favourite spirit, flavour profile, or a theme. The cocktail appears on the printed menu card with their name. This is included free on all milestone birthday packages (30th, 40th, 50th, 60th). For standard birthdays, it's a £50 add-on that includes recipe development and a tasting before the event.
