Holidaymakers returning from Switzerland, Jamaica and the Czech Republic must quarantine for 14 days upon their return to the UK from 4am on Saturday.
Transport secretary Grant Shapps said the three countries had been removed from the travel corridors list, while Cuba had been added meaning returning tourists would not have to self-isolate.
He tweeted: “Quarantining on return from a non-Travel Corridor country is a legal requirement and you commit a criminal offence if you break that quarantine. Fines, as well as a criminal record can result.
“The decision on whether to add or remove a country is carefully made after research from the Joint Biosecurity Centre. A lead indicator is 20 cases per 100k over 7 days but they take into account a wide range of factors, including level, rate & speed of change in confirmed cases.”
