Discussions on whether France should be placed on the red travel list are active in Whitehall under pressure to make a final decision within a few days.
Some health numbers are understood to push to make the change, which will mean that everyone returns from France having to pay thousands of pounds for mandatory 10-day hotel quarantine on return.
However, ministers have in the past been reluctant to impose too much disruption across the British-French border because it is such an important point of trade and travel.
Negotiations are ongoing and a positive decision to place France on the red list will require ministerial agreement across the government.
Sources have told Sky News that a decision must be made within a few days and before the end of the school term, which ends for most English public school students next Friday.
If a decision is made after this point, there may not be enough hotel room capacity to handle the numbers that need to carry out mandatory quarantine when they return.
Case rates in France are far lower than in the UK, although they are rising.
According to our world in data, in the week to 14 July there were 244,691 UK COVID cases, while in France in the same period there were 27,713 cases.
France has 44% Alpha cases – more than any other type – followed by Delta, which accounts for 28% of cases. Almost every case in the UK is Delta.
A Downing Street spokesman said they were constantly monitoring the situation.
On Thursday, it was announced that The Balearic Islands, which includes tourist hotspots from Ibiza, Mallorca and Minorca, is moved back to the yellow travel list from kl. 4 Monday.
On the same day, the rules on travel change, which means that people who are fully vaccinated and under the age of 18 do not have to isolate themselves after returning from countries on the yellow list.
Although they still have to take a test three days before returning and have a PCR test on day two back in the UK – but not on day eight.
The move to the Balearic Islands will primarily affect younger adults, as they are more likely not to have received two COVID-19 vaccinations.
People arriving in the UK from green countries do not need quarantine but must take a private PCR test two days after returning.
However, some holiday destinations have their own quarantine rules, so travelers may have to isolate themselves on arrival even if they do not in the UK.
