The Foreign Office (FCDO) said that arrivals in Italy from the UK would have to “show evidence that you tested negative in a test administered in the 72 hours before your travel”.

“You should not use the NHS testing service to get a test in order to facilitate your travel to another country. You should arrange to take a private test,” said the FCDO in its travel advice to Italy, which was updated on Thursday (8 October).

But, rather confusingly, the FCDO advice added: “Alternatively, you can get a free test on arrival at some airports, or at a testing facility in Italy shortly after you arrive. If you test positive within Italy, you will be required to quarantine.

“The time spent in quarantine can vary greatly from a few days to several weeks. Travellers should be prepared for this eventuality.”

Italy currently has a travel corridor with the UK meaning that those returning from the country do not have to quarantine for 14 days when they get back to the UK. But this could change when transport secretary Grant Shapps gives his latest update.
