Britain reported 94,326 new COVID-19 cases on Tuesday and 439 more deaths within 28 days of a positive test, official data showed.
The figures compared to 88,447 cases and 56 deaths reported on Monday.
The number of deaths is the highest recorded since Feb. 24 last year. The figure are often higher on a Tuesday when most deaths at the weekend are included in the tally. Last Tuesday, 438 deaths were reported.
Overall case numbers, deaths and hospital admissions have been slowly falling from a peak after Christmas.
Meanwhile, France posted 501,635 new cases of coronavirus for the past 24 hours on Tuesday, a new daily record and the first time the headline number has surpassed half a million.
The country is currently recording the highest daily infection rates of any major European nation, with an average of more than 360,000 over the past week.
More than 30,000 people are in hospital with coronavirus across France in the highest such tally since November 2020, official figures showed.
But only a little more than 3,700 were in intensive care, less than during previous periods of high infection.
The highly contagious omicron variant that is fueling the latest wave is believed to be less dangerous than the previous dominant strain delta.
Some 364 people died of the virus in the past 24 hours, bringing the total number of deaths from COVID in France to 129,489.
The latest figures came after new COVID rules came into force in France on Monday.
People are now required to be vaccinated against COVID-19 to enter bars, restaurants, trains and planes.
A negative coronavirus test will no longer be enough to access leisure activities, some work events and long-distance travel.
More than 77 percent of France's population has received 2 shots of an anti-Covid vaccine.
How France emerges from the current wave is seen as crucial in April presidential elections, in which President Emmanuel Macron is widely expected to run although he has yet to declare his candidacy.
Despite the high caseload, Prime Minister Jean Castex last week announced a timetable for lifting Covid restrictions in France from February 2. — With an Agence France-Presse report
