I was in a similar position a couple of years ago, having not flown for almost twenty years. 1 hour trial flight, medical, 3.5 hours further flying skills brush up
AND COMPLETE THEORY AND PRACTICAL FOR ISSUE OF NEW "FLIGHT RADIO TELEPHONY OPERATOR'S LICENCE" (FROTL). I was then signed off by my instructor to go solo (in circuit only), followed by LST. No theory tests required other than the RT stuff, though I did buy the latest books and studied them as if I was going to be tested - in flight is not the best place to realise you've forgotten something! Getting back into flying was the best thing I ever did.
