This week, the UK Government is expected to announce a ‘green list’ of destinations to kickstart summer holidays. Overseas travel has been off the cards for months, but the traffic light system – due to come into effect on May 17 – will make them possible once again. British holidaymakers will be able to travel home from the ‘green’ countries without needing to enter quarantine. It is expected that only a small number of countries will feature on the green list. The majority of Europe is expected to fall on the ‘amber’ list (meaning home quarantine on return to the UK) and the 40 countries on the ‘red’ list will likely remain the same. So when will the green list be announced? And which countries are likely to be ‘green’? How will the traffic light system work? Green Holidaymakers returning from green destinations will have to take a negative Covid-19 test within 72 hours of departure, and then pay for a PCR test on or before the second day of their return to the UK (even if fully vaccinated). They will not have to quarantine. Amber Holidaymakers returning from “amber” countries will have to self-isolate at home for 10 days. Amber travellers will also have to have a pre-departure test and book and pay for two PCR tests on days two and eight of their home quarantine. If they want to release quarantine early, they can pay for a PCR test on day five (but will still have to take the test on the eighth day, as well). Red British people returning from “red” countries have to quarantine for 10 days in government-approved hotels at a cost of £1,750 per person, with pre-departure tests and tests on days two and eight.
