The UK CAA tightened the rules on this a few years back, because of exactly the reason you are talking about. The rules here are you may only log P1/s when succesfully completing a flying test, PPL NFT, GFT etc. As you are in Sweden you will have to check with their authorities, our CAA will probably only accept what they say anyway. Hopes this helps! (In the airline world it is a bit different in case anyone is wondering.)
