According to the BBC, travel corridors were introduced in the summer to allow people travelling from some countries with low numbers of COVID-19 cases to come to the UK without having to quarantine on arrival.
The closure now means anyone flying into the country from overseas will have to show proof of a negative COVID-19 test before setting off.
The UK has been one of the hardest-hit countries by the pandemic, with over 84,000 people already dead.
Meanwhile, restrictions continue to cost the UK economy.
The economy slumped 2.6 percent in November on coronavirus restrictions, official data showed Friday, stoking fears that the current virus lockdown could spark a double-dip recession.
