Introduction All international arrivals to England must quarantine for 10 days, unless they have a job that qualifies for an exemption. All international arrivals in quarantine are required to take a test on or before day 2 (of their quarantine period), for variant surveillance, and a test on or after day 8 (of their quarantine period). Private providers may provide tests for day 2 and day 8 testing for international arrivals travelling from countries that do not have a travel ban (non ‘red list’ countries). From 26 April, private providers may provide tests for day 2 and day 8 testing for international arrivals who have been in or transited through a ‘red list’ country in the 10 days before their arrival.
