The death toll, based on mentions of Covid-19 on death certificates, reached 1,273 on 16 January – the highest number of deaths to take place on a single day in the second wave so far.
But the figures could rise even higher once all deaths have been registered for the second half of the month.
The provisional data has been published by the Office for National Statistics (ONS).
It shows that a total of 117,378 deaths had occurred in the UK by 22 January, where coronavirus was mentioned on the death certificate.
For the 14 days from 7 to 20 January, the daily death toll was above 1,000.
During the first wave of the virus in April 2020, there were 23 consecutive days when the death toll was above 1,000.
