I still have an advice of refund and refund code sent to me by post. Can I use them to claim a refund after 2 April 2024?

A refund code sent by post will remain valid after 2 April 2024 and can still be used to claim the refund in question. As soon as you use the code, the refund will no longer be displayed in Central Fee Payment for direct claiming. Please note that from now on we will not be issuing codes for refunds which can be directly claimed in Central Fee Payment.
