If you’re travelling to England for less than 10 days, you will need to quarantine for the whole of your stay. You must still book your day 2 and day 8 travel tests, even if you will no longer be in England on the dates of the tests. You only need to take the tests if you’re still in the country on those dates. You do not need to quarantine or take a day 8 test if you are fully vaccinated in the UK, Europe or USA.
