18th Birthday Helium Balloons Delivered

Turning 18 deserves a proper celebration. Send 18th birthday balloons delivered ready-inflated in a box, with ribbon and weight attached, as a surprise gift, or have them sent to the party as instant decoration.

Choose from rose gold, black and gold, navy and silver and bright rainbow designs, giant number balloons, or a personalised 18th birthday bubble balloon with their name. Bunches and larger displays make a bigger statement.

18 helium balloons, ready to float

Every balloon on this page arrives filled with helium, so there's nothing to inflate. Choose a pair of giant 34-inch "1" and "8" number balloons, a single 18th design, or a bunch of 3, cluster of 5, arrangement of 7 or bundle of 9.

How long will they float?

Foil balloons usually float for 3 to 5 days indoors, sometimes up to a week; large foil and number balloons for 5 to 7 days or more; and bubble balloons for up to two weeks. Our guide to how long helium balloons last has tips.

Pick your delivery date on the product page; we recommend the day before the party. Order by 1pm Monday to Friday for next working day delivery. Need decorations too? See our 18th birthday decorations, or 18th balloons to inflate yourself.
