How Long Does Helium Last?

A common question before any event: how long does helium last in balloons? It depends on the balloon type.

Plan your float time

Latex floats for hours and foil for days — inflate close to the event, and we will help you pick the right helium.

Disposable & refillable choice

Grab a single-use canister for a one-off party, or step up to a refillable cylinder for weddings, events and trade balloon work.

Collection & local delivery

Collect from our Kent base and stockist network, or order helium online for local delivery — inflate where the party is.

Float times

How long different balloons hold helium

  • Latex balloons — typically float for around 12 to 24 hours. A Hi-Float coating inside the balloon seals the latex and can extend this considerably.
  • Foil balloons — hold helium far longer, often several days to a couple of weeks, because the foil leaks gas much more slowly than latex.

Temperature matters too: heat expands the gas and speeds up leakage, so balloons fade faster in a hot room or direct sun.

Make them last

Tips for longer float time

A few simple habits keep balloons up longer:

Inflate close to the event rather than days ahead, treat latex with Hi-Float for a longer float, choose foil where you need balloons to last, and keep them out of heat and direct sunlight. Avoid over-inflating — a slightly under-filled balloon copes better with a warm room.

Frequently asked questions

How long does helium last in a latex balloon?

Usually around 12 to 24 hours. A Hi-Float coating inside the balloon can extend the float time considerably.

How long do foil balloons stay up?

Foil balloons hold helium far longer than latex — often several days to a couple of weeks, as the foil leaks gas much more slowly.

How do I make helium balloons last longer?

Inflate just before the event, use foil balloons or treat latex with Hi-Float, and keep balloons out of heat and direct sunlight.
