Transport secretary Grant Shapps has promised "certainty" of the government’s travel corridor list over the Christmas and New Year period.
Shapps said on Thursday (17 December) countries would only be removed from the list in an emergency during the next two weeks.
The next travel corridor update will be on Thursday 7 January.
He additionally announced Uruguay, Namibia and the US Virgin Islands are to be removed from the travel corridor list.
Arrivals from any of the three destinations will have to self-isolate for 10 days as of 4am on Saturday (19 December).
Shapps announced the latest changes to the travel corridor list in a string of tweets posted shortly after 5pm.
It comes after the Canary Islands were removed from the list last week, while Saudi Arabia and Botswana were added.
"Latest data means we must remove Uruguay, Namibia and [the] US Virgin Islands from the travel corridor list," said Shapps.
"From 4am Saturday 19 December, if you arrive into the UK from these destinations you will need to self-isolate.
"Providing certainty to those travelling over Christmas, we will only make emergency removals to the travel corridor list if needed for the next two weeks. Next regular update 7 January."
