Birthday party bar hire in London starts from £850 all-inclusive for up to 35 guests. The Sesh Bars turn any venue into a proper cocktail bar for your birthday — bespoke menus, a named signature cocktail for the guest of honour, licensed bartenders, and a bar that looks as good as it pours. We've covered 30ths in Hackney lofts, 40ths in Richmond gardens, 50ths in Mayfair townhouses, and 21sts in Clapham house shares. Indoor and outdoor setups across all London boroughs.
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.
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.

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.

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.
Peak birthday season runs May through September and throughout December. Book at least four weeks ahead for Saturday nights during these months — availability moves fast, especially in central and east London. Weekday birthdays and off-peak months can usually be confirmed within two weeks.
