I didn't renew my C1 when I did my licence on turning 70 ( no MH at the time) Now we're considering upping the plate because of all the kit carried. Can anyone explain ( simply!) what I need to do to get the C1 back. Does it involve medicals, retests etc. or is it a paper exercise with just forms filled in by a GP. I've looked at the .GOV website and am now more confused than ever
