It is generally possible to cancel your application for shares/bonds at any point before the closing date of an offer, unless the business in which you have invested has already accepted your investment during the course of their fundraise. If the business has already 'drawn down' your money and issued you with shares/bonds it will not be possible to cancel your investment and receive a refund.  To cancel any application please send a request by email Please note that if you have paid by debit card then any transaction fee cannot be refunded upon cancellation.
