Hi, In that case, you have a licence for life I believe. You just need to revalidate your Class Rating. This page seems to cover it: https://www.caa.co.uk/General-aviation/Pilot-licences/Applications/Ratings/Keeping-your-ratings-valid/ You'll probably also want to consider converting to an EASA licence (this used to be just a paperwork exercise, I'm not sure about the procedure now). Note, I am note an Instructor or Examiner, so don't take what I say as read. A lot more knowledgeable people hang out at the other Internet Forum, so you may get more authoritative answers there. Andy
