DAP: our quicker service, usually taking 5-10 days. Customs charges are payable on delivery, and your courier will contact you to arrange payment.

Returns & Exchanges
We’re unable to accept returns or exchanges as each piece is made to order. If your item arrives damaged in transit we can offer a return or replacement. Photographic evidence is required and we’ll open an investigation with the courier before processing the claim.

Important Safety Information:

All inflatables are not flame-proofed as standard. For indoor events requiring fire safety compliance, we recommend purchasing synthetic fire retardant spray online, which can be easily applied before use. When properly treated, these props will typically meet British Standards certification requirements. Always check your venue's specific fire safety regulations.
