Back in March, France had relaxed the rules for Brits and other EU citizens.
But starting Monday "compelling reasons will be required for non-EU foreigners who are not residents in France and who come to France from the United Kingdom", the ministry said in a statement.
However, the ministry added that there would be "no systematic checks" to ensure compliance with the requirement, "given the low incidence of Covid in Britain".
"There is a new situation with the progression of the so-called Indian variant in the United Kingdom," said government spokesman Gabriel Attal. "(France) will set up compulsory isolation for people coming from the United Kingdom."
It comes just days after France added the UK to its mandatory quarantine list with arrivals from the UK being required to self-isolate for seven days over fears of the Indian variant.
France had previously warned the UK of potential travelling restrictions due to the rise in Covid-19 cases.
It had said the country would not introduce an outright ban but would ensure extra measures would be in place.

"We hope that the variant can be controlled in a country which experienced real failures during the pandemic.
"However, the arrival of the Indian variant and the increase of cases of Indian variant in the United Kingdom pose a problem and so we are vigilant about this [and] in contact with the British authorities."
The French government's announcement will have a great impact on the tourism industry, which is desperate for a return to normalcy ahead of the summer season.
"It's reasonable in terms of saving the French summer but will be very punishing for those regions which depend on British holidaymakers," said Ge Kusters, owner of Le Paradis campsite in the Dordogne area and president of the regional campsite union.
"More financial support is going to have to follow."
Currently France has only full vaccinated 15.4 per cent of its population and administered 34.3m jabs in total, according to Our World in Data.
