Fully-vaccinated passengers returning to England, Scotland and Northern Ireland from France will no longer need to quarantine after Sunday.
Under widespread changes to the traffic light system for travel, France is being moved from amber-plus to amber.
It was added to the list last month amid concerns about the Covid Beta variant, which scientists believe may be more resistant to vaccines.
However the travel industry says the government has not gone far enough.
Germany, Austria and Norway are among seven nations being added to the green list as part of the changes.
Bahrain, Qatar and the United Arab Emirates have been moved from the red list to the amber list. But Mexico is among four countries now considered to be among the highest risk destinations going on to the red list.
The changes from 04:00 BST on 8 August raise the total number of countries or territories on the green list – where all travellers can return from without having to quarantine – from 29 to 36.
