The move was confirmed by the UK’s four chief medical officers on Friday (11 December) after Wales cut its self-isolation requirement to 10 days earlier this week.
In a statement, they said: "After reviewing the evidence, we are now confident we can reduce the number of days that contacts self-isolate from 14 days to 10.
"People who return from countries which are not on the travel corridor list should also self-isolate for 10 days instead of 14 days."
Additionally, from 15 December, arrivals into England from non-travel corridor destinations will be able to use the government’s "test and release" scheme to potentially leave quarantine after just five days.
