Travel from the Philippines, Pakistan, Kenya, and Bangladesh is to be banned from next week, the government says.
They are being added to England’s “red list” amid concerns about the spread of new Covid-19 variants.
From 04:00 on 9 April, international visitors who have traveled from or through those countries in the previous 10 days will be refused entry.
An exception is made for British or Irish passport holders or people with UK residence rights.
But they must first pay to quarantine in a government-approved hotel for 10 days.
No direct flight bans from the four countries will be put in place, but passengers are advised to check their travel plans before departing for England.
Under the current rules, foreign travel from the UK is banned apart from for exceptional reasons.
The earliest date people from England will be able to travel abroad for a holiday is 17 May, when the government hopes to move to step three of its lockdown exit plan.
