The Sesh Bars celebrate your engagement with a complete bar service — champagne reception, a bespoke cocktail designed for the two of you, and professional bartenders at any London venue. Gardens, marquees, private dining rooms, members' clubs. All-inclusive packages start from £1,000. This one is worth doing properly.
Engagement party bar hire in London costs from £1,000 for a four-hour all-inclusive package for up to 40 guests, including a champagne or prosecco reception and a bespoke signature cocktail designed for the couple. The Sesh Bars provides a mobile bar unit, licensed bartenders, quality glassware, and complete setup at private gardens, marquees, members' clubs, and hired venues across all London boroughs and Berkshire. Premium Champagne upgrades (Moet, Veuve Clicquot, Laurent-Perrier Rose) are available. Zero-proof cocktails are included as standard for non-drinking guests.
Engagement parties in London span a wide range of venue types. Private gardens in North London (Hampstead, Primrose Hill) and West London (Richmond, Chiswick) suit summer celebrations with 40-120 guests. Rooftop bars and private dining rooms in Central London work well for intimate evening events. Warehouse spaces in Shoreditch and Hackney suit couples wanting a creative, informal setting.
For marquee engagement parties in Berkshire — particularly Windsor, Ascot, and Henley — the countryside setting pairs well with a champagne reception on the lawn followed by cocktail service inside the marquee. Our bar units are marquee-compatible and require no plumbing. See our packages and pricing for full rates, or request a quote.
Every engagement party bar hire booking includes a mobile bar unit, licensed bartenders, a bespoke cocktail menu, quality glassware, ice, garnishes, and full setup and strike. A champagne or prosecco reception service is included on all engagement packages — our bartenders manage glass-charging and top-ups throughout the welcome so nothing falls short.
All-inclusive packages cover every drink from arrival champagne to late-night cocktails: premium spirits, cocktail ingredients, beer, wine, soft drinks, and non-alcoholic options. Upgrades to premium Champagne labels are available. Public liability insurance and personal alcohol licences are included on every booking at no extra cost.
Engagement parties call for a drinks menu that feels celebratory from first glass to last. Our cocktail consultation designs a short list anchored around the couple's signature cocktail — created with your flavour preferences in mind and named after you on the menu card. Popular base menus for engagement parties include the French 75, Aperol Spritz, Velvet Bramble, and Espresso Martini alongside the bespoke signature.
Non-alcoholic cocktails are included as standard on every package — our zero-proof menu covers the same flavour profiles so non-drinking guests, pregnant friends, and designated drivers all have something worth raising. See our full cocktail menu for the complete drinks list and individual prices.

A champagne reception on arrival is the standard opening to every engagement package. Our bartenders pre-charge glasses and manage top-ups throughout the welcome period so guests are never without a glass. The reception flows naturally into the main bar service — we time the transition to match your event schedule.
Prosecco is the default on standard packages. Upgrades to Moët & Chandon Brut, Laurent-Perrier Rosé, or Veuve Clicquot are available at a supplement — confirm your preference at the booking stage. For a pre-wedding feel, this pairs well with our wedding bar hire service, which offers the same champagne reception model for the big day itself.
