Five more countries have been added to the quarantine exemption list – Estonia, Latvia, Slovenia, Slovakia and St Vincent and the Grenadines.
The so-called "travel corridors" pose “a reduced risk to the public health of UK citizens”, according to the Department for Transport.
However, the list remains “under constant review”.
Announcing the new additions, the Government said anyone who arrived in England from the destinations before Tuesday will still need to self–isolate.
It comes after the UK removed Spain from its catalogue of safe countries after fears were raised that the European country was experiencing a second wave of coronavirus infections.
It means those returning from the country, including the Balearic and Canary islands, will have to self-isolate for two weeks upon their return to the UK.
