The government's 'travel corridors' list is ever-changing with quarantine rules for travellers changing rapidly.
Visitors from other countries are permitted into England and the rest of the UK but may have to quarantine depending on the country they travelled from - and they will be required to adhere to national restrictions.
The introduction of 'regional travel corridors' means the list has become more complex, with islands now being considered separate to their mainlands.
The government reduced the length of self-isolation for people arriving from nations that were not exempt from the list from 14 days to 10 days on December 11.
Popular destinations such as France and Spain are among the countries which were once considered safe, but have been removed from the list following spikes in coronavirus cases.
Approved destinations pose “a reduced risk to the public health of UK citizens” but the list will be kept “under constant review”, the Department for Transport said.
The Foreign and Commonwealth Office are keeping travel destinations under review, meaning the list is subject to change.
The full list of countries for which quarantine will not apply to people arriving back in England:
Antigua and Barbuda
British Antarctic Territory
British Indian Ocean Territory
