An update from the Office for National Statistics (ONS) covering the first three months of 2020 showed gross domestic product (GDP) fell by 2.2% compared to the previous quarter.
It had previously given an initial reading of 2%.
The number-crunchers said the revised figure meant the economy had endured its worst quarterly fall since 1979.
Jonathan Athow, deputy national statistician at the ONS, said: “Our more detailed picture of the economy in the first quarter showed GDP shrank a little more than first estimated.
“This is now the largest quarterly fall since 1979.
“Information from Government showed health activities declined more than we previously showed.
