🚨 IMPORTANT HIRE INFORMATION 🚨

To keep our inflatables and equipment in the best possible condition for all customers, please ensure the following items are never used on or near the hire equipment:

  • Food or Drink

  • Cigarettes / E-Cigarettes

  • Face Paints

⚠️ Balloons

All balloons must be removed from the inflatable before collection.
If your hire is overnight, please ensure no balloons are left on the equipment. Balloon colours can run, especially in damp or wet conditions, which may cause permanent staining. For this reason, balloons should not be placed on inflatables in wet weather.

Understanding Sizing Measurements

  • Unit Size: This is the manufacturer’s listed size of the inflatable, showing the minimum flat grass space required. Example: A 12ft x 12ft bouncy castle will need a 12ft x 12ft grass area for safe setup. For full dimensions, see the size tab on each product listing.

  • Required Space: This refers to the overall clear space needed for safe operation, free from obstacles. Example: A 12ft x 12ft castle that requires 16ft x 16ft means you’ll need the 12ft x 12ft base area plus 2ft of clear space on every side, away from walls, fences, washing lines or posts.
