Passengers attempting to get to the UK must have a negative coronavirus test within 72 hours of departure. Otherwise they will be denied flying.
Boris Johnson said ministers would take steps to ensure people arriving in the country are free of Coviden.
Government sources told MailOnline that the details of the policy were being "solidified".
An announcement is expected in a few days, with rules expected to be in effect by the end of the week.
It has raised fears that there will be an onslaught of Brits – like Amber Gill from Love Island and Amber Turner from Towie, who are both in Dubai – trying to get home.
But Labor and some senior Tory MPs called for further action when England went through its third national lockdown.
It comes as Home Secretary Priti Patel was accused of leaving the "doors of the nation unlocked" to alert new coronavirus variants.
Meanwhile, ministers have been criticized by the travel industry for having plans to test passengers for Covid-19 before they arrive.

Travelers must have a negative PCR test within 72 hours before being allowed to fly to the UK.
The rules apply in all countries, regardless of whether there are travel corridors.
Those entering ports or airports from “red list” areas where cases are high are expected to be quarantined even if they test negative
Anyone forced to self-isolate on arrival will be disfellowshipped if a second test is negative from day five.
They will be given a passenger tracking form and will face a £ 10,000 fine for not following the rules.
Shadow Home Secretary Nick Thomas-Symonds wrote to Ms. Patel requesting an "urgent review and improvement plan" as he raised concerns about the controls on arrivals
Shadow Home Secretary Nick Thomas-Symonds wrote to Ms. Patel requesting an "urgent review and improvement plan" as he raised concerns about the controls on arrivals.
Mr Thomas-Symonds wrote: "It is particularly worrying given concerns about the mutation of the virus that emerged in South Africa, which the Minister of Health rightly describes as" incredibly worrying ".
However, the lack of a robust quarantine system due to government shortcomings means it is virtually impossible to control this spread or any other variant that could have come from overseas, leaving the UK defenseless and completely exposed The nation's doors have been opened to more Covid mutations. & # 39;
The Home Office defended its "strict measures", pointing to its move to halt direct flights from South Africa to the UK amid concerns about a new variant of the coronavirus that is widespread there.
Mr. Thomas-Symonds stated that Ms. Patel's protection against variant strains arriving from overseas was "virtually non-existent", citing government statements that only 3 percent of arrivals expected to be quarantined in England and Northern Ireland would be successful in the summer contacted by compliance auditors.
A government spokesman replied, “The numbers in this letter are inaccurate. Border Force performed more than three million spot checks and PHE (Public Health England) contacted an additional 1,500 people daily.
& # 39; We are determined to reduce the spread of the coronavirus. Our strict measures, such as mandatory forms for tracking passengers and spot checks both at the border and during the quarantine period, have shown a high level of compliance. & # 39;
Concern about the South African variant is particularly high as it is not only viewed as more contagious, but also fears that it could interfere with current vaccines, unlike the novel strain which has achieved high prevalence in England.
Direct flights from South Africa to the UK were suspended last month and many newcomers who have been there in the past 10 days will not be allowed entry.

Conservative former Health Secretary Jeremy Hunt on Monday called for borders to be closed, and an off-scale winter crisis is brewing inside the NHS.
Ahead of the Prime Minister's lockout on Monday, the chairman of the Commons Health and Social Care Committee wrote on Twitter: "Time to act: thread why we need to close schools and borders and prohibit all household mixing RIGHT AWAY."
The interior minister of the SNP, Joanna Cherry, accused the government of "repeating the same mistakes" by not imposing "effective" restrictions on the border.
She said: "The UK government must stop all but essential travel and put in place a much stricter system of health checks and border quarantine."
The prime minister said Tuesday he would "take steps to ensure we test people who come to this country and prevent the virus from resuming".
Ministers are believed to be considering introducing an obligation for international arrivals to test negative for coronavirus before traveling to the UK to address the growing cases. Freight forwarders would be exempt.
Currently, arrivals to England from countries not exempt from the travel corridor program must be isolated for 10 days.
However, as part of the testing and approval scheme introduced in December, this can be shortened if a private test is carried out five days after their departure and the result is negative.
During the initial lockdown, the government opposed the introduction of border restrictions, while the prevalence in the UK was so high. Experts argued that doing little would help lower infection rates.
However, a quarantine period was introduced in June after the first peak and when the cases were better under control.
Meanwhile, the ministers were criticized by the travel industry last night for having plans to test all passengers for Covid-19 before arriving in the UK.
Industry leaders said they had been calling for such a regime since last summer and accused ministers of trembling.
The measures, which were beaten up by ministers last night, are expected to be announced within a few days.
Sources said there had been a last-minute dispute between the Home Office and the Department of Transportation over whether UK residents should also be tested, with the DfT reportedly only trying to test foreigners.
The plans, which would bring the UK in line with many other countries, mean passengers must provide evidence of a negative PCR test result before boarding a flight, ferry or train to the UK.
It would need to be dated no more than 72 hours prior to their expected arrival on British soil. There will be a limited number of exceptions, including for freight forwarders.
Airport Operators Association Chairman Baroness Ruby McGregor-Smith said: "We have asked for it since early summer and no one has done anything about it."
Lloyd Figgins, Managing Director of Travel Risk & Incident Prevention Group, said, “I think the industry would have welcomed this back in March, and if we look at the countries that have put these restrictions in place, they have benefited longer term to infection and keep the industry going. & # 39;
