⚠️ Important Hire Information

❄️ Winter Bookings

October to March

During winter months, inflatables are available for indoor hire only due to weather and safety conditions.

Suitable venues include halls, sports centres, community centres and indoor event spaces.


🌱 Artificial Grass / Astroturf

If your event is on artificial grass or astroturf, we must be able to securely anchor the inflatable.

This usually requires staking through the surface into the ground below.


💬 Not Sure? We’re Happy to Help

If you’re unsure about your setup, surface or venue, please contact us before booking and we’ll be happy to guide you.
