Hire Period Information

Hire Charges. *Daily hires charges are based on units being delivered between 9am - 11am and collected between 5pm - 6pm, Beyond 6pm the late collection/overnight charges will apply. Our standard daily rates also apply when only hiring the equipment for 2 -3 hours (i.e. having a party in a hall, etc)

Winter season bookings. We always aim to provide our customers with the best quality equipment. For this reason we do not hire our inflatables OUTSIDE between 1st November and 31st March. We can thus ensure that all castles booked for parties indoors during this period are dry and clean every time

Village hall bookings. Although hire charges are based between 9am - 6pm, we can deliver and collect at any time to suit your plans. If you have a hall booked for 2 - 3 hours we can fit in with your plans and have the castles delivered and set up before the children arrive, and then collect just after they have gone home. (Please note specific times are on a first come, first served basis)
