To get the most from your gas cylinder learn to size your balloons - here.

All cylinders purchased from 'balloon.co.uk' are on hire. The above prices include 1 months rental.

THE CYLINDERS MUST BE RETURNED OR YOU BE CHARGED FOR RENTAL. You are paying for the helium inside the cylinder - you do not own the cylinder.

We try to give a realistic number for the amount of balloons each cylinder will inflate. Other suppliers may show different inflation quantities than above but we feel 750, 500 & 250 is a realistic number of 10" balloons for each cylinder.

Cylinders can be delivered and collected anywhere in mainland Britain for £35+vat (some areas in Scotland are restricted).
