If WWF is forced to cancel sessions for reasons outside of our choice/control or a participant requires a refund after booking then WWF have the right to retain the booking fee of up to £4 (depending on the cost of the activity, £1 booking fee + 2.6%) when making refunds. Cancellation would be the last resort and would often be due to a key partner influence such as either a school or venue cancelling our delivery/booking.
