All sponsorship monies will be retained by the National Autistic Society unless your sponsors request in writing that the charity return it to them within one month of your cancellation (not applicable for online donations). If you choose to defer your place to a future event after the official console deadline has passed, you must pay a deferral fee of £50 to secure your place in a future event.
