What do you mean "just recently heard about the new requirement for a new radio license" Surely all licences have a requirement for a valid FRTOL. I just had a quick look at the CAA website, and don't see anything 'new'. Emails should be followed up with letter if item is important. You do not say if you are employed or not. Never rely on a phone call get what you need in writing in good time direct from the CAA. I am not sure that I can help you but your post has not been replied to probably because it is missing important detail.
