I was intrigued by your question and looked for an answer. I hadn't realised quite how poor the CAA website is. I knew that in the EASA process glider licensing was steadily pushed to the right. Did it ever come to be? Now that the UK and EASA have gone their seperate ways one might have expected reference to it to have been removed from the CAA website but its still there. I tried to simply find out how to obtain a glider licence but I couldn't find a simple satisfactory answer.
