Mickey Kayes' answer is corect for the UK but in Florence it will be a little more complicated. You will need an EASA medical certificate as a Medical Dec will not be valid in Italy. As you have a UK issued licence you will need to convert it to an EASA licence to use it in Italy, SRG 1104 is the form. Probably the simplest option is to do a SEP Proficiency Check with an Examiner authorised by the UK, could bel at an Italian Club, you will also need a SRG 1199 signed by a UK Examiner for English Language Proficiency, and a certification of all documents before sending the SRG1104 to the UK for the issue of an EASA licence.
