You sound as if you are UK tax resident and so can invoice from the UK (even if the work is performed in Italy) and pay tax there. Unless you are tax resident in Italy, it should not require any official documents etc in Italy. Of course, if you are employed on a permanent contract in Italy it would be more complicated.
