While most workers had an increase in earnings in 2021, the gender pay gap also grew, the Office for National Statistics said.
Latest figures showed the gap between male and female earners was 7.9 percent for the month of April.
The ONS pointed to the fact this was greater than the seven percent gap seen in April 2020, and stressed it had been driven by the pandemic.
It said the figures were caused by men’s pay rebounding after being hit worst in 2020.
Unions warned that the gender pay gap remained a serious injustice in the UK.
TUC general secretary Frances O’Grady said: “Women are still getting a raw deal at work when it comes to pay.
“At this rate, it will take decades to close the gender pay gap.”
