Britain reported just four deaths in latest daily Covid-19 figures on Monday, the lowest number of deaths since September, according to government statistics.
Death totals are often lower on Mondays due to delays in reporting deaths over the weekend.
There were 2,963 new Covid-19 cases reported, with 32.93 million people receiving a first Covid-19 vaccine dose.
More than 10 million in the UK people have now received two doses of a Covid-19 vaccine.
The figures come as the country imposes its strictest travel curbs on India after a surge of coronavirus cases there.
Prime Minister Boris Johnson also called off a trip to New Delhi.
It would have been Johnson's first major foreign visit since he took power in 2019.
"In the light of the current coronavirus situation, Prime Minister Boris Johnson will not be able to travel to India next week," the two governments said in a joint statement.
Health Secretary Matt Hancock said that effective from 3am on Friday, India was being added to Britain's "red list" of countries, banning all arrivals from India except for UK or Irish nationals.
Those nationals, as well as foreigners resident in the UK, must pay hefty amounts to stay in a government-approved quarantine hotel for 10 days on their return from red list nations, which include Pakistan and Bangladesh.
"We've made the difficult but vital decision to add India to the red list," Hancock told parliament, after the government had faced days of criticism for holding off the decision, pending Johnson's trip.
