Milestone birthday sets for Knebworth weddings and parties
A milestone birthday deserves a moment. Our milestone sets bring together our giant light-up numbers, a personalised backdrop with the birthday name and a balloon garland styled in your colours, so you have one stunning display for photos, the cake and the big reveal.
Knebworth is famous for big nights, and we bring the same energy to weddings and parties here: LED dancefloors, DJs, selfie pods and cold spark machines, delivered, set up and collected by our own team.
Go elegant with gold, ivory and chrome, glam with black and gold, or fun with a theme like a casino night. Joint birthdays work beautifully too, with both names on the backdrop.
