I had this with a student who was in the same situation. I asked Fred Cross at The Belgrano as I couldn't find the answer. He came back with 2 hours and a skills test, after that it is 2 hours a year including LPC. that will then cover you for all SET providing you have done 2 hours in other types. You now do not need to do alternate tests according to EASA
Hope that helps
Now if you were to renew SET on a type on your licence you will need to do 2 training sessions ( not necessarily flying) and an LPC
